VCB Chassis is the key part used in switchgear for assembling and moving circuit breakers, transformers with below details:
VCB Chassis installation and movement: Mainly used for withdrawable switchgear equipment, providing an installation basis for circuit breakers, transformers and other components, and realizing the push-in and pull-out operations of these components, facilitating the inspection, maintenance and replacement of equipment
Ensure electrical Connection and Safety:When internal structure of the chassis and the circuit breaker work with other interlocking switchgear, the relevant "five-protection" interlocking requirements can be met.For example, the circuit breaker can only be connected when the trolley in the test/disconnection or working position, and the trolley cannot be moved after the circuit breaker connected to prevent accidental operation of the isolation contacts under load; when the trolley is in the working position or a certain distance away from the test/disconnection position, the earthing switch cannot be connected to avoid malfunction of the earthing switch, etc.
