Outline and size diagram of the switch cabinet
A Handcart
The trolley skeleton is made of thin steel plate processed by CNC machine tool after riveting and welding.According to the use, the car can be divided into circuit breaker car, voltage transformer car, isolation car, metering car, and so on, the same specifications of the car can be easily exchanged.The hand car has an isolation position, test position and working position in the cabinet, and a positioning device is equipped in each position to ensure that the hand car can not move casually when it is in the above position, and the interlocking must be removed when moving the hand car.
B Bus room
The bus leads from one switchgear to another and secured by the branch busbar and static contact box.Flat branch busses are bolted to the static contact box and the main busbar, without any other wire clamp or insulator connections.The connection bolts on the bus row can be insulated and end caps when specially required by the user and the project.Attach the bus casing through the partition of the switch cabinet.If an internal fault arc occurs, the accident can be limited to the adjacent cabinet and can guarantee the mechanical strength of the busbar.
C Cable vault
In the cable room, current transformer, grounding switch, lightning arrester and cable and well, detachable aluminum plate can be installed at the bottom to ensure the convenient construction of the site.
