DescriptionGeneral


3TL vacuum contactors are three-pole contactors

with electromagnetic operating mechanism formedium-voltage switchgear. They are load breaking

devices with a limited short-circuit making

and breaking capacity for applications with high

switching rates of up to 1 million electrical operatingcycles or 3 million mechanical operating cycles.

Switching medium

The vacuum switching technology, proven and fully

developed for more than 30 years, serves as arc-quenching

principle by using vacuum interrupters.

Construction

3TL vacuum contactors consist of a medium-voltage and alow-voltage part. Together with the main conductor

terminals, the vacuum interrupters constitute the

medium-voltage part. All components required to operate

the vacuum interrupter, such as the operating mechanism,

closing latch and control unit make up the low-voltage part.

These components can be arranged either one behind the

other (3TL6) or one above the other (3TL7 and 3TL8).

Application examplesThe vacuum contactors are suitable for operational switching

of alternating current consumers in indoor switchgear, and

can be used, e.g., for the following switching duties:

Motor starting

Plugging or reversing the direction of rotation of motors

Switching of transformers

Switching of reactors

Switching of resistive consumers such as electrical

furnaces

Switching of capacitors.

With these duties, the contactors are used in conveying

and elevator systems, pumping stations, air conditioning

systems as well as in systems for reactive power

compensation, and can therefore be found in almost every

industrial sector.

In contactor-type reversing starter combinations (reversing

duty), only one contactor is required for each direction of

rotation if HV HRC fuses are used for short-circuit protection.

Construction of the 3TL6 vacuum contactor(front view)


Mode of operation

The atmospheric pressure exerts a force on the metal

bellows of the vacuum interrupter. Without the influence of

the operating mechanism, this would close the contact gap.

The opening springs (6) keep the moving interrupter contact

in open position via the integral rocker (10). To close the

vacuum contactor, the compressive force of the opening

springs (6) is overcome by the magnet system (2). The

magnet armature (4) is attracted, thus moving the integral

rocker (10), which releases the moving interrupter contact

from the open position. The atmospheric pressure closes the

contacts. The integral rocker (10) compresses the contact

pressure springs (16), thus generating the necessary contact

force. When the magnetic excitation is de-energized, theopening springs (6) open the contact gap via the integral

rocker (10) and the moving interrupter contact. The DC

magnet system operates as an economy circuit, proving a

high mechanical endurance and a low pickup and holding

power.


The latch (7) holds the vacuum contactor in closed position

even without excitation of the magnet system. When themagnet system is energized, the integral rocker is latched

mechanically in the CLOSED position through a lever and

roller system. The vacuum contactor is released electrically

by means of a latch release solenoid (9) or mechanically by

the tripping bolt (8).

Mechanical closing lock-out

The mechanical closing lock-out (5) prevents unintentional

closing of the vacuum contactor, e.g. due to vibrations orwhile racking the withdrawable part. During operational

switching, the closing lock-out is inactive.

3TL6 vacuum contactor (continuation)

Adjustment to the site altitude

At the factory, the vacuum contactor is adjusted to a site

altitude of 200 m to + 1250 m above sea level. For other

site altitudes, the contactor must be adapted to the

corresponding site altitude range by means of adjusters

located on the rear side of the device (see figure on the

right).

Blocking element to interlock two contactors

To interlock two contactors mutually for reversing duty,

a mechanically operating blocking element is available on

request (for 3TL61 only). The blocking element is fixed

between the two contactors, blocking the movement of the

operating rocker of the two contactors alternatively. This

excludes a phase short-circuit that could occur when the two

directions of rotation are activated simultaneously as a result

of mechanical impact and electrical maloperation.


Construction

3TL7 vacuum contactors have two slim pole shells abovethe operating mechanism. The vacuum interrupters (2) are

fixed between two pole half-shells (1). This design enables

easy and universal installation on the different switchgear

and frame structures. The low-voltage part contains the

magnetic drive, auxiliary contactor and auxiliary contacts.

Mode of operation

The magnetic drive of the 3TL7 vacuum contactor opens and

closes the contacts of the vacuum interrupters. Due to theuse of a special double coil, the magnetic drive is designed

for the closing and holding process.

Mode of operation

3TL8 vacuum contactors open and close the contacts of the

vacuum interrupters (2). Due to the use of the electronic

economy circuit (12), the magnet system (11) is to a large

extent independent of the voltage type and level.


The mechanical closing latch (6) holds the vacuum contactor

in closed position even without excitation of the magnet

system (11). The latching module of the mechanical closing

latch (6) is accommodated in the mechanism section.

When the magnet system (11) is energized, the vacuum

interrupter (2) is latched mechanically in CLOSED position

through a lever and roller system. The vacuum contactor is

released electrically by means of a latch release solenoid or

mechanically by a tripping bolt (customer control required).

The command duration for the latch release coil must range

between 100 ms and 1 s. De-energizing must be provided

externally.

Utilization categories

In IEC 60470, power contactors are divided into different

utilization categories. According to these categories, 3TL

vacuum contactors are dimensioned for different electrical

consumers and operating conditions. The opposite table

shows typical applications in accordance with the respective

utilization categories.

Application

3TL vacuum contactors are 3-pole contactors with

electromagnetic operating mechanism for medium-voltageswitchgear. They are load breaking devices with a limited

short-circuit making and breaking capacity for applications

with high switching rates (> 10000 operating cycles).

Vacuum contactors are suitable for operational switching of

alternating-current consumers in indoor switchgear, and can

be used e.g. for the following switching duties:

Switching of three-phase motors in AC-3 or AC-4 operation

Switching of transformers Switching of reactors

Switching of resistive consumers

Switching of motors

3TL vacuum contactors are especially suitable for frequent

operation of motors. As the chopping currents of the

contactors arew 5 A, no unpermissibly high overvoltages are

produced when accelerated motors are switched during

normal operation. However, when high-voltage motors with

starting currents ofw 600 A are stopped during start-up,switching overvoltages may arise. The magnitude of these

overvoltages can be reduced to harmless values by means of

special surge limiters. 3EF surge limiters can be arranged in

parallel to the cable sealing ends, preferably in the cable

compartment. The surge limiters consist of non-linear

resistors (metal-oxide varistors SIOV) and a series-connected

spark gap. During installation it must be observed that the

surge limiter is flexibly mounted on one side for mechanical

reasons.

Switching of transformers

When inductive currents are interrupted, current chopping

can produce overvoltages at the contact gap. Such

overvoltages can be controlled with a protective circuit

composed of 3EF surge limiters.

Switching of capacitors

3TL vacuum contactors can interrupt capacitive currents upto 250 A up to the rated voltage of 12 kV without restrikes,

and thus without overvoltages.

Surge protection via limiters

Overvoltages can arise as a consequence of multiple

restrikes or by virtual current chopping, e.g. when motors

are switched in braked condition or during start-up. Motors

with a starting currentw 600 A are endangered. Safe protec-

tion against overvoltages is ensured by surge limiters; circuitexamples are shown above.

Short-circuit protection via HV HRC fuses

At high short-circuit currents, HV HRC fuses have a

current-limiting effect, i.e. the fuse limits the short-circuit

current to the let-through current. When selecting the fuses,

the type of consumer must be observed, e.g. motor, trans-

former, capacitors.

The diagram shows an example for the coordination of a

HV HRC fuse with an overcurrent-time protection.

Co-ordinating the components of the motor circuit:

The time-current characteristic must be located on the

right of the motor starting current (point A).

The rated current of the HV HRC fuse-link must exceed the

normal current of the motor.

The current corresponding to the intersection B of theHV HRC fuse-link characteristic and the characteristic of the

overcurrent-time protection must be higher than the

minimum breaking current of the HV HRC fuse-link.

If this is not feasible, it must be ensured that overload

currents that are smaller than the minimum breaking current

of the HV HRC fuse-link are interrupted by the switching

device via the striker. This prevents thermal overloading of

the HV HRC fuse-link, which would otherwise be destroyed.

The selected HV HRC fuse link limits the sustained

symmetrical short-circuit current Ik to the let-through current

ID shown in the diagram for the current-limiting

characteristics (ID as a function of IK for HV HRC fuse-links

with different rated currents). The maximum permissible

let-through current is ID = 50 kA.

Requirements

The let-through currentI

D must not exceed 50 kA to 7.2 kV In case of low-voltage supply via a control transformer,

short-circuit currents ranging above the limit switching

capacity must be interrupted within 80 ms This requirement

Short-circuit protection for class E2 controllers

according to UL 347/CSA C22.2

For using 3TL6 and 3TL8 vacuum contactors as class E2

controllers for 7.2 kV, Siemens fuses of type 3GD1 150-4D

(7.2 kV/250 A) or other fuses with a comparable current-

time characteristic are specified for short-circuit protection.

If two fuse-links are connected in parallel, the symmetrical

short-circuit current determined has to be divided by two,

and the associated let-through current for one fuse-link must

be stated. This value must then be multiplied by two in order

to obtain the total let-through current, which must not

exceed the permissible value for the vacuum contactor.

The parallel connection should ensure that the resistance

values in the two branches are almost the same. When the

fuses operate, the vacuum contactor must be switched off.

A suitable device, actuated by the striker of the HV HRC

fuse-link, should be provided.

Fuse monitoring

To prevent a three-phase load (e.g. a motor) from being

supplied only by two phases when a fuse has operated, the

fuse-bases can be equipped with a fuse trip indicator. This

device can be used either to energize a warning signal or to

switch off the vacuum contactor.Short-circuit protection by circuit-breakers

Consumers for which no suitable fuses are available can also

be protected by circuit-breakers. Due to the longer break

time of the circuit-breakers (max. permissible 120 ms), the

symmetrical short-circuit current must not exceed the

maximum permissible value (e.g. 20 kA at 7.2 kV for 3TL6

vacuum contactors). As a consequence of the longer

opening time, the interrupters should be replacedimmediately by new ones after carrying the maximum

permissible symmetrical short-circuit current, as their service

life has been considerably reduced.

Standards

3TL vacuum contactors are designed in open construction,

with degree of protection IP00 according to IEC 60529 and

DIN EN 60529. They conform to the standards for

high-voltage alternating current contactors above 1 kV and

up to 12 kV:

IEC 60470

UL Standard 347

CSA C22.2

As there are no standards available for 24 kV, 3TL7 vacuum

contactors are designed according to

IEC 60470, Edition 05.2000 / DIN EN 60470 Edition

01.2002

DIN EN 62271-100 Edition 01.2004.
