The electrical power supply for railway systems requires

circuit-breakers with special features. Not only are theresingle-pole circuit-breakers in normal operation, but also

the high requirements regarding operational reliability

and number of operating cycles reach far beyond thestandards of other applications.

The vacuum circuit-breaker series 3AH47 offers – both for

162/3 Hz at a rated voltage of 17 5 kV and for 50/60 Hz at

3AH47 vacuum circuit-breakers control up to 60,000

operating cycles Minimum maintenance work such as

The 3AH47 vacuum circuit-breaker consists of the pole

assembly (1) and the operating mechanism box (2). The pole

assembly is fixed to the operating mechanism box via post

insulators (3). The switching movement is transferred by

means of operating rods (4) and levers.

Switching medium

The vacuum switching technology, proven and fully

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

principle by using vacuum interrupters.

Pole assembly

A pole assembly consists of the vacuum interrupter (6) and

the interrupter supports. The vacuum interrupter is air-

insulated and freely accessible. This makes it possible to clean

the insulating parts easily in adverse ambient conditions.

The vacuum interrupter is mounted rigidly to the upper

interrupter support (5). The lower part of the interrupter is

guided in the lower interrupter support (7), allowing axial

movement. The braces absorb the external forces resulting

from switching operations and the contact pressure.

Operating mechanism box

The whole operating mechanism with releases, auxiliary

switches, indicators and actuating devices is accommodated

in the operating mechanism box. The extent of the

secondary equipment depends on the case of application

and offers a multiple variety of options in order to meet

almost every requirement.

Operating mechanism

The operating mechanism is a stored-energy mechanism.

The closing spring is charged either electrically or manually.

It latches tight at the end of the charging process and serves

as an energy store. The force is transmittedfrom the operatingmechanism to the pole assembly via operating rods.

To close the breaker, the closing spring can be unlatched

either mechanically by means of the local “ON” pushbutton

or electrically by remote control. The closing spring charges

the opening or contact pressure springs as the breaker

Releases

A release is a device which transfers electrical commands

from an external source, such as a control room, to the

latching mechanism of the vacuum circuit-breaker so that it

can be opened or closed. How many releases are used and

how they are combined is defined when the secondary

equipment is selected.

• The closing solenoid unlatches the charged closing spring

of the vacuum circuit-breaker, closing it by electrical means.

• Shunt releases are used for tripping the circuit-breakers

via protection relay and for manual tripping via electrical

operation. For this purpose they are operated with an

auxiliary voltage (AC or DC) supplied by the protection relay

or the control room.

• Instantaneous releases are used for switching duties withextremely short breaking times, especially for applications in

162/3 Hz systems, in order to keep the arcing time short. For

operation of the instantaneous release, a capacitor tripping

unit is required additionally.

• Undervoltage releases comprise a stored-energy mechanism,

an unlatching mechanism and an electromagnetic system,

which is permanently connected to voltage while the

vacuum circuit-breaker is closed.If the voltage falls below a predetermined value, unlatching

of the release is enabled and the circuit-breaker is opened

via the stored-energy mechanism.

Closing

In the standard version, the 3AH47 vacuum circuit-breakers

can be remote-closed electrically. They can also be closed

locally by mechanical unlatching of the closing spring via

pushbutton.Instead of this “manual mechanical closing”, “manual

electrical closing” is also available. In this version, the closing

circuit of the circuit-breaker is controlled electrically by a

pushbutton instead of the mechanical button. In this way,

switchgear-related interlocks can also be considered for local

ti i d t t i l t l i

Circuit-breaker tripping signal

The NO contact makes brief contact while the vacuum

circuit-breaker is opening, and this is often used to operate

a hazard-warning system which, however, is only allowed

to respond to automatic tripping of the vacuum circuit-

breaker. Therefore, the signal from the NO contact must

be interrupted when the circuit-breaker is being openedintentionally. This is accomplished under local control with

the cut-out switch that is connected in series with the NO

contact.

Interlocking

Mechanical interlocking

The switch position of the circuit-breaker is checked from the

switchgear side, and its closing is blocked if the associated

disconnector is in faulty position. On the other hand, dis-

connector operation is prevented while the circuit-breaker is

closed. Accordingly, the mechanical interlocking can also be

usedto interlock against circuit-breaker trucks or withdrawable

parts.

Electrical interlocking

The vacuum circuit-breakers can be integrated in electro-

magnetic feeder or switchgear interlocks. In case of electrical

interlocking, the disconnector or its operating mechanism is

equipped with a magnetic lock-out mechanism. This

mechanism is controlled by an auxiliary contact of the

circuit-breaker, so that the disconnector can only be

operated when the circuit-breaker is open. On the other

hand, the circuit-breaker is also controlled by the

disconnector or its operating mechanism, so that it can only

be closed when the disconnector is in an end position. For

this purpose, manual electrical closing must be provided inthe circuit-breaker operating mechanism (see “Closing”).

Standards

3AH47 vacuum circuit-breakers conform to the following

standards:

• EN 50152-1

Ambient conditions

The vacuum circuit-breakers are designed for the normal

operating conditions defined in IEC 62271-100.

Condensation can occasionally occur under the ambient

conditions shown opposite. 3AH47 vacuum circuit-

breakers are suitable for use in the following climatic classes

according to IEC 60721, Part 3-3:

Climatic ambient conditions: Class 3K4 1)

Biological ambient conditions: Class 3B1

Mechanical ambient conditions: Class 3M2

Chemically-active substances: Class 3C2 2)

Mechanically-active substances: Class 3S2 3)

1) Low temperaturelimit: – 5 °C2) Without icing andwind-driven precipitation3) Restriction:Clean insulation parts

Current carrying capacity

The rated normal currents specified in the opposite diagram

have been defined according to IEC 62271-100 for an am-

bient air temperature of + 40 °C and apply to open switch-

gear. For enclosed switchgear the data of the switchgear

manufacturer applies. At ambient air temperatures below

+ 40 °C, higher normal currents can be carried (see diagram):

Characteristics curve 1 = Rated normal current 1250 ACharacteristics curve 2 = Rated normal current 2000 A

Characteristics curve 3 = Rated normal current 2500 A

Dielectric strength

The dielectric strength of air insulation decreases with

increasing altitude due to low air density. According to

IEC 62271-1, the values of the rated lightning impulse

withstand voltage and the rated short-duration power-

frequency withstand voltage specified in the chapter“Technical Data” apply to a site altitude of 1000 m above

sea level. For an altitude above 1000 m, the insulation level

must be corrected according to the opposite diagram.

The characteristic shown applies to both rated withstand

voltages.
