Chassis Truck for KYN61-40.5 Switchgear is mainly used in 40.5kV removable switchgear to push/pull out the circuit breaker, transformer and other component trolleys as an auxiliary operation for connecting components to the busbar. When the push mechanism works in conjunction with the internal mechanism of the circuit breaker and other interlocks of the cabinet, it can meet the "five-protection" interlocking requirements in GB3906.

Product Advantages

Chassis Truck for KYN61-40.5 Switchgear has many advantages:

Screw nut structure

Generally, a screw nut propulsion mechanism is used. This structure can convert rotational motion into linear motion to achieve smooth advancement and withdrawal of the circuit breaker trolley.

Effort saving feature

The transmission mode of the screw nut has the advantage of labor-saving, and the operator can easily move the circuit breaker handcart without spending too much effort, reducing the difficulty and labor intensity of operation.

Self locking function

It has self-locking performance. When the handcart reaches the designated position (such as the working position or test position), it can automatically lock to prevent accidental movement of the handcart due to external forces or other factors, ensuring the safe and stable operation of the equipment. For example, during the work process, even if subjected to certain vibrations or collisions, the handcart can remain in a fixed position.

Convenience of operation

The operation is relatively simple. The trolley can be pushed and withdrawn by operating the handle or related control devices. Operators can master the operation method proficiently after simple training, which improves work efficiency.

Interlocking coordination

It cooperates well with other components of the circuit breaker and the interlocking device of the switch cabinet to jointly realize the "five-defense interlocking" function. That is, the circuit breaker can only be opened and closed when specific conditions are met (such as the test position or working position and the valve of the propulsion mechanism is in the closed position, etc.); the trolley cannot be opened and closed during the propulsion process; the propulsion mechanism cannot be used when the circuit breaker is in the closed position, etc., effectively preventing misoperation and improving the overall safety of the equipment.

Low maintenance cost

It has low maintenance requirements and relatively simple daily maintenance. Only regular cleaning, inspection and necessary lubrication and other maintenance work are required. Moreover, its structure is relatively simple and has fewer parts. When a fault occurs, it is easy to troubleshoot and repair, reducing maintenance costs and downtime.

Product Applications

Chassis Truck for KYN61-40.5 Switchgear is a KYN61-40.5 switch cabinet kit, which is used to propel all removable parts such as ZN85 series circuit breakers and various trolleys.
