KYN61-40.5 Metal Armored Pull-out Switchgear
KYN61-40.5 Metal Armored Pull-out Switchgear
I. Overview
KYN61-40.5 metal armored pull-out switchgear is a switchgear developed by the company combining the advanced technology and advantages of similar switchgear at home and abroad. It is widely used in single-bus and single-bus segmentation of three-phase AC 50HZ and rated voltage of 35KV. Power system. As power plants, substations, industrial and mining enterprises, they receive and distribute electrical energy and control, protect and monitor circuits.
KYN61-40.5 switchgear can be equipped with the latest generation of vacuum circuit breakers produced by Cutler-Hammer (formerly Westinghouse Westinghouse) representing the world's advanced level or the excellent SF6 circuit breaker produced by Schneider and ABB's VD4- 40.5 series vacuum circuit breakers. Domestically available vacuum circuit breakers such as ZN85-405 (3AV3) and ZN72-405 can be configured according to user needs. The secondary circuit of the switchgear can be equipped with a comprehensive protection and monitoring device with reliable performance. The switchgear is a switchgear with advanced technology, stable performance, reasonable structure, convenient use, safety and reliability.
II.The main features
1: The structure of the cabinet is assembled, and the circuit breaker adopts the floor-standing structure of the handcart;
2: It is equipped with a new type of composite insulated vacuum circuit breaker, which has the characteristics of good interchangeability and simple replacement;
3: The screw nut propulsion mechanism is installed in the trolley frame, which can easily move the handcart and prevent the misoperation and damage the propulsion mechanism;
4: All operations can be performed with the door closed;
5: The interlock between the main switch, the handcart and the switch cabinet door adopts the forced mechanical locking mode to meet the “five-proof” function;
6: The cable room has sufficient space to connect multiple cables;
7: Fast grounding switch for grounding and loop short circuit;
8: Shell protection level P4X handcart room door open state, protection level P2X;
