Production description
KYN61-40.5 type intelligent armored removable AC metal-enclosed switchgear
product description
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 the 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.

Product Features:

A. The body of the switchgear has a package structure and the circuit breaker has a truck falling type structure.
B. It is fitted with a new type of compound and insulating vacuum circuit breaker or SF6 gas protection breaker. It is featured by good
interchangeability and easy alternation.
C. There is a propelling mechanism of feed screw nut in the trolley shelf, which makes it easy to move the truck
and can prevent the incorrect operation from damaging the propelling plant.
D. All of the operations shall be in the condition of cubicle door closed.
E. The interlock between the main switch, trolley, and the cubicle body is mandatory mechanical latching and has function of "Five protection".
