SWITCHGEAR COMPARTMENT

In this compartment, the SF6-filled RV-44 load break switch of the “sealed for life” type, acts as the physical separation between the busbar set and the cable compartment. The switch has two functions: it connects or interrupts the electrical current between the high voltage cables and the busbar.

BUSBAR COMPARTMENT

The busbar compartment is located in the upper part of the cubicle and behind the low-voltage compartment. The modular busbar set is manufactured from specially pro-vided electrolyte F25 copper. Several cubicles are connected through the bar set compart-ments. Hexagonal bolts connect the busbars to the upper contact surfaces of the RV-44 load break switch.

CABLE COMPARTMENT

The cable compartment is located behind the interlocked, removable door of the DF-2 cubicle. This part of the field receives the cable(s) and contains the necessary equipment to connect the cable(s). The earthing switch is installed below the load break switch on the right side, ensuring a “visible earthing” when the earthing switch is closed. In a DF-DT cubicle, the cables are connected to the contact points below the RV-44 load break switch. DF-DT types have the earthing switches located in the cable compartment below. The removable door, the sectional floor panels, which house the necessary conductive rubber for the cables, and the cable supports, all simplify the cable connection.

LOW-VOLTAGE COMPARTMENT

The drive mechanism that controls the RV-44 load break switch and the earthing switch EM 98 is fitted with the synoptic diagram and is located behind the front panel. Several accessories, such as the auxiliary contacts, switch-on or switch-off coils, and minimum voltage relays, are also located in this compartment. Any engine control with the necessary electrical switchgear, a control and clamp strip are also installed in this compartment. The compartment can be accessed very easily by removing the front panel.

Compartments of the cubicle


Internal Arc Resistance

The various tests were always in accordance with IAC (AFL) for 16kA/20kA/1s. according to IEC 62271-200.

before test (IAC 20 kA/1 sec.

after test (IAC 20 kA/1 sec.

A short-circuit or another malfunction can create an internal arc. An internal arc in a classic MV cubicle, could severely damage the installation and possibly injure the operator and electrocute him or her.

The DF-2 is designed to resist internal arcs, protecting both the operator and the installation. Through a strategic pressure release system, the internal arc is restricted to the compartment where it originated and it does not propagate towards the operator or to other compartments.

The anti-arc kit of DF-2 cubicles is specifically designed to minimize the consequences of an internal arc. By default all provided cubicles are fitted on the rear side with overpressure valves pointing downward, in order to release the hot gasses upward.

The four valves are equally spaced among the total height of the cubicles: The upper valve is for the busbar and the three other valves protect both the cable compartment and the equipment compartment. The cubicle roof is fitted lengthwise over a depth of 100 mm.

Upon delivery, two reinforced side plates will be supplied in order to close the cabin completely, both to the left and right sides against the wall. At the rear of the cubicle, a buffer volume will be provided, in order to release the hot gasses upwards.

For applications in accessible concrete outdoor cabins, the anti-arc kit allows gasses to be diverted to the basement area. There is an exhaust opening in the floor panel along the side of the wall specifically for this purpose.

DF-2 cubicles were tested at Kema IAC (AFL) for 16kA/20kA/1s. at a rated voltage of 17.5 kV/24 kV according to IEC 62271-200, appendix A and met the 5 criteria.

Consequently, all Power Technologies cubicles are internal arc resistant.


Visible earthing switchThe earthing switch is installed below the load break switch on the right side, ensuring a “visible earthing” when the earthing switch is closed.

This is the online safe manner in which the operator can visually check the position of the switch through the windows in the door of each cubicle. The switching takes place in the air. The two controls, the load break switch and the earthing switch, have been accommodated in one control mechanism. As the requirments of the IEC standard have been met, these two controls are also mutually interlocked mechanically whereby any incorrect switch operation is excluded.

It is important to mention that the Earthing Switch mechanism is also completely independent of the operator. An interesting feature is that the earting point can be very easily assembled and disassembled, and is virtually maintenance free. High safety is due to the operator always being able to see the state of the earting contacts through the windows.

Remote Switching & Monitoring Device(optionally)High energy efficiency, lower operational costs, increased lifespan of the equipment, eliminating equipment downtime, ensuring uptime. As a plant, production, maintenance, installation manager or technician you feel increasing the pressure day in day out, to let the equipment and installations perform more efficient, at a lower cost for a longer lifespan and still ensuring a higher productivity rate.

Transitions options and control modesConfigurable for Open- or Closed-Transition Transfer

Switches may be configured for open or closed-transition transfer.For either configuration, if the primary source is lost, the control initiates an open-transition transfer to the emergency source by tripping the breaker from the primary source and closing the breaker to the emergency source.For open-transition transfer, once power has been restored, retransfer to normal is accomplished by reversing this process - first tripping the breaker from the emergency source and then closing the breaker to the primary source. The two sources cannot operate in parallel, it’s open-transition transfer system.For closed-transition retransfer to the normal source, the PTS-InteliV5 control’s power monitoring functions ensure that both sources are within an acceptable window of synchronism before effecting a closed-transition retransfer to the normal source by first closing the normal sourcebreaker and then opening the emergency source breaker. It’s possible for load to betransferred from Source 1 to Source 2 without interruption of power to the load when both sources are available. The source paralleling during load transfer is less than 100 milliseconds.

Adjustable Center-Off Time Delay

In open-transition transfers between two live sources where large inductive loads are involved, induced voltage transients can result in a lack of synchronism between the sources, causing a bump upon transfer. A time delay between the opening of the primary source breaker and the closing of the secondary source breaker allows these voltage transients to decay. This center-off delay is factory preset at 3 seconds, but can be adjusted via the PTS-InteliV5 control.Center-off positioning is ideal for loadshed control schemes.

Manual Bypass/Isolation Capability

PTS Series Medium-Voltage Circuit-Breaker Bypass/Isolation Switches provide all the functions of an automatic transfer switch plus the ability to bypass power from a live source to load in the event the transfer switch becomes disabled. In addition, they are designed to allow isolation and de-energization of the automatic transfer breaker for maintenance, testing, or repair.Operator can easily choose between load-break bypass or no-load-break bypass by means of a selector switch on the front of the control cubicle.Compartmentalized design ensures personnel safety and simplifies installation.Sequencing of circuit breakers allows for open or closed-transition transfer.PTS-InteliV5 programmable microprocessor based control system.
