StructureThe switchgear consists of two parts: cubicle and withdrawable parts. The cubicle are made of high quality steel plate (zinc plate coated with aluminum can also be used at the customers' request). The degree of protection for the enclosure is IP4X and IP2X (when the door of the circuit breaker compartment is open). The switchgear can be equipped with VB2 type withdrawable vacuum circuit breaker truck or fixed type load switch. The rails of truck are assembled on the middle side of the cubicle to avoid fault that the disconnecting contacts of the truck can not engaged with the contacts fixed in the cubicle caused by the floor out of shape. At the same time, the height of the power cable terminal can be rised and the convenience for operation and maintenance improve. The switchgears can be arranged face to face but can not be installed against wall.

*Only for the structure 650mm in width ; Once there is a switchgear with 650mm in width, the depth of the other cubicles will change accordingly.When cables come in switchgear from the top, then should add rear channel cabinet with 200mm depth. When the busbars come in from the top, should add rear channel cabinet with 350mm.

Truck compartment The truck compartment is on the middle front of the cubicle. Mount specified truck rail on both sides of the compartment for the truck to move along between the test and servicing positions. On the rear cover of the compartment , there is bushing type CT or bushing spouts and protective metal shutters, which can be moved up and down. The shutters can open automatically during truck moving to servicing position from test position; the movable contacts will be inserted into the fixed contacts. When the truck moves into test position, the protective shutters will go down to cover the fixed contacts to make it isolated. This can protect personnel from touching the live parts.The operation of the truck shall be carried out with the door of the cubicle closed. The position of the truck can be viewed through the window on the door. In the meantime, the close/open button on the breaker panel and position indicator, indicator for spring charging also can be viewed.

Withdrawable PartsBased on the purposes , the withdrawable parts can be classified as circuit breaker truck, PT truck, link truck, metering truck and etc. The same truck can be interchangeable easily. The primary arms installed on each phase are all equipped with spring fingers. Trucks can be in test and servicing positions, each of which has a locating device to ensure the trucks is allowed being operated only when they are at the proper positions.Before the truck is moved, the breaker should be in open.

Busbar compartmentThe upper rear of the cubicle is main busbar compartment . Main busbars can be led from one cubicle to another. The bushings installed on the partition not only support the main busbar but also prevent the faulty spreading to the adjacent cubicle. Branched busbar can be connected to the main busbar and bushing spout with bolts. All busbars can be covered with heat-shinkable tubings according to customer' s special requirements.The busbar joints can also be covered with insulation boot.

The enclosure and partition The enclosure of the switchgear is made of folded high quality steel plates connected with fasteners. The assembled switchgear has integrity in dimension. The cubicle is divided into truck compartment , busbar compartment , cable compartment and LV compartment by metal partitions. Each function unit is separated from others.

Cable compartmentThe lower rear of the cubicle is cable compartment , in which current transformer, earthing switch and arresters can be installed. With the rear cover plate removed, the operator can enter the cubicle to install cables. 1 or 3 cables can be connected to the terminal in parallel at the same time. The Height of the cable terminals can reach 680mm. In the bottom of the compartment there is removable steel plate as well as cable clips and seal rings with variable radius.In addition, heaters are set in both truck compartment and cable compartment to prevent condensation caused by high ambient humidity.

Pressure-relief All the truck compartments, busbar compartment and cable compartment have pressure relief duct. In the case that internal arc fault occurs to the truck, busbar or cable compartments, the pressure inside the compartment rise. The pressure-relief plate will be opened automatically to release pressure and gas. At this time because the seal ring installed on the door is enclosed, the safety of the operators in front of the panel is guaranteed.

Earthing DeviceThere are fixed earthing contacts on both sides of the truck compartement , and there are moveable earthing contacts installed on both sides of the truck to ensure that the truck be earthed reliably from the test position to servicing positon. The earthing resistance is less than 300 μΩ.After the cubicle is arranged properly, earthing busbar of cubicles be connected and be connected to the earth.

InterlocksPerfect and reliable interlocks facilities are incorporated to ensure safe operation. These include the following: a. Only when earthing switch is in Open (at this time the rear

cover can’t be open), can the truck be racked in from test position to servicing position.

b. Only when the breaker is in open , can the truck be racked between the test position and servicing position in cubicle.

c. When the earthing switch is closed (at this time the rear cover can be open), the truck can’t be racked in from the test position to serving position.

d. When the rear cover is open, the earthing switch can’t be open .

e. The earthing switch can be closed, only when the breaker truck is on test position or outside the cubicle.

f. When the truck is on servicing position, the secondary plug will be locked and can’t be removed.

g. Only when the breaker truck is on test position or servicing positon, can the breaker carries out opening and closing operation.

h. All the doors of HV compartments are equipped with locks and be opened or closed with special tools.

Note: It is allowed to use capacitive voltage detection system.

LV compartmentLV compartment is on the upper front of the cubicle.The secondary instruments such as the metering instruments, operating switch, buttons and relays, etc, can be installed. There are some little holes on the side plate of the compartment for wirings.
