KYN61-40.5(Z) Armored removable AC metal enclosed switch cabinet

/[]
1. Overview
Armored removable AC metal-enclosed switch cabinet (hereinafter referred to as switch cabinet) is an indoor complete power distribution device with three-phase AC capacity and rated voltage. It is used to receive and distribute electric energy in power plants, substations and industrial and mining enterprises. It controls, protects and detects circuits and can also be used in places with frequent operations.

IV. Structure
The switchgear cabinet structure adopts assembled type, and the circuit breaker adopts handcart floor-standing structure with brand new Type composite insulated vacuum circuit breaker, and has good interchangeability. The handcart frame is equipped with a screw nut propulsion mechanism, which can easily move the handcart and prevent misoperation from damaging the main switch, handcart, and switch cabinet door of the propulsion mechanism. The interlocking between them adopts the forced mechanical locking method, which meets the five-proof function. All operations can be performed with the cabinet door closed. The cable room has ample space and can connect multiple cables. The quick grounding switch is used for grounding and loop short circuit. Housing protection level 3. Protection level when the handcart room door is open.
