KYN61-40.5 air-insulated metal-clad withdrawable switchgear (hereinafter as switchgear is a kind of HV switchgear.It is designed as a withdrawable module type panel, and the withdrawable part is fitted with VD4-36E,VD4-36 withdrawable vacuum circuit breaker manufactured by Boerstn Electric Company . It can also be fitted with isolation truck, PT truck, fuses truck and so on. It is applicable to three phase AC 50/60 Hz power system,and mainly. Boerstn Electric co. design and make this withdrawable switchgear under the standard of IEC62271-200.etc
KYN61-40.5 armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear) is used with a three-phase AC 50/60HZ, voltage 40.5kv power system, used to receive and distribute electrical energy and control, protect and monitor the circuit .
Intelligent technology is mainly reflected in the following aspects:
1. Adopt an intelligent switch cabinet operating system
(1) The circuit breaker of the switch cabinet enters, exits, opens and closes to realize remote control or local electric operation.
(2) The grounding switch of the switch cabinet is opened and closed to realize remote control or local electric operation.
(3) All primary contact parts in the switch cabinet adopt visual interface and temperature measurement methods to ensure the safe connection of all contacts.
2.Adopt intelligent information processing system to diagnose and monitor the failure precursor of the switchgear body
(1) On-line detection and over-limit monitoring of busbar and cabinet temperature.
(2) On-line monitoring of operating characteristics of circuit breaker opening and closing speed.
(3) Online monitoring of the mechanical performance of the operating mechanism.
(4) Online detection and alarm of insulation level.
3. Intelligent anti-misoperation operating system
(1) Prompts and previews of various operations.
(2) Check the operation and lockout of misoperation.
(3) Prohibit operation prompts and operating condition prompts.
4. Intelligent function of secondary circuit
Intelligent measurement, signal, protection, control and movement.
5. Remembrance of grid failure
Wave recording, login, simulation replay and fault recording, provide analysis data.
