• The DPC-4-800M/300 Indoor VCB Motor Trolley Chassis Truck 24KV is designed for high-performance indoor vacuum circuit breakers (VCB) applications. It is engineered for use in medium-voltage switchgear systems with up to 24kV. This motorized trolley is known for its reliable operation, easy mobility, and compact design, making it an ideal choice for power distribution and industrial facilities.

  VCB Chasis truck mainly used for switch equipment to install circuit breaker, transformer and other components, push and exit it, play a supplementary role in connecting the components with the busbar.

  VCB Chasis trucks are available in two versions: DPC- 4 -800 for circuit breakers up to 1600A and interfacial distance to 210, 275 mm, And DPC- 4 -1000 to switch from 2000A to 3150A , with an interfacial distance up to 275 mm. In trolley mounted auxiliary contacts its provisions (operating or control ), as well as all the necessary locks. Bred to pull lock breaker racking included, as well as reed for interlocking with earthing. Depth racking 200, 300mm.

   

  Working principle

  The hand-carrying circuit breaker has two positions in the switchgear, namely the working position and the isolated position. When the circuit breaker is in the working position, the main circuit of the switchgear is connected with the main circuit of the circuit breaker; and when the circuit breaker is in the isolated position, the main switchgear The circuit is disconnected from the main circuit of the circuit breaker. The switching of the two positions of the circuit breaker in the switchgear is achieved by the movement of the chassis of the hand-cranked circuit breaker. Since the main circuit is a high-voltage live accessory, the movement of the circuit breaker must be unlocked in the chassis lock device, that is, the chassis car lock device controls the chassis car to carry the circuit breaker in the switch cabinet.

  

  The control module is developed for the motor chassis truck. It is installed in the low-voltage room of the switchgear. It is used for the electric access control and protection device of the electric chassis. It can simplify the engineering design, reduce the secondary wiring work of the switchgear and improve the reliability.

  Main functions

  1. Meet the basic control requirements of the handcart shake and shake, and the interlocking requirements of the circuit breaker and grounding switch.

  2. With motor over-current protection function, the over-current can be adjusted to protect the motor.

  3. Over-current return function, if there is abnormality in the process of rocking, the motor can be returned to the test position when it is over-current, or it can be stopped in half-turn.
