indoor armored removal of the exchange of metal-enclosed switchge KYN61-40.5KV
KYN61-40.5 refers to the armored removed type AC metal enclosed switchgear (hereinafter referred to as switchgear) is a three-phase AC 50Hz, rated voltage 40.5KV indoor complete power distribution device. As a power plant, substation and industrial and mining enterprises to accept and distribute the power of the circuit to control, protection and detection functions, can also be used for frequent operation of the place. Switch equipment cabinet structure using assembly-type, circuit breaker floor structure with handcarts; equipped with a new composite insulation vacuum circuit breaker, and good interchangeability; hand car frame with screw nut propulsion mechanism can be The main switch, handcart, switchgear door interlocks are used to force the mechanical locking mode, to meet the "five anti-" function; all operations are available in the cabinet door Close to the state; cable room ample space can be connected to multiple cables; quick grounding switch for ground and circuit short circuit; shell protection class IP4X, handcart door open, protection class IP2X.
Use of the environment
1. Ambient air temperature upper limit: +40 ℃, lower limit: -10 ℃, the daily average temperature does not exceed 35 ℃;
2. Altitude not exceeding 1000m;
3. Relative humidity is not more than 95% on average, the monthly average of not more than 90%;
4. Seismic intensity does not exceed 8;
5. The average daily water vapor pressure is not more than 2.2Kpa, the monthly average of not more than 1.8kpa;
6. No fire, explosion hazard, serious pollution, chemical corrosion and severe vibration of the place.
KYN61-40.5 switchgear has a series of interlock devices. Fundamentally prevent the dangerous situation and may cause serious consequences of the operation. Thus effectively ensuring the safety of the operating personnel and the switchgear itself.
Switchgear in the following operations, the need to meet the interlock conditions, otherwise the operation will be blocked.
Push the handcart part from the test position to the working position:
The circuit breaker is in the "minute" position
Ground switch in the "sub" position
The part of the handcart exits from the working position to the test position:
Circuit 5S in the "minute" position
Operating Circuit Breaker:
The handcart is locked in the test position or working position
Operation earthing switch:
The handcart is partially locked in the test position
The cable compartment door is closed
The security used
So as to realize various operations of the switch in the case where the high-pressure chamber door is closed.
Completely metal armor and closed, closed when the shell protection class IP4X, effectively protect personal safety.
Good insulation of the main circuit to switchgear compact structure, saving floor space.
Adaptability, easy to implement a variety of programs to meet different user needs.
Hand-car interchangeability, in the cabinet to move effort, balance.
Cable room has ample space, can connect multiple cables, easy installation and maintenance.
Mechanical interlocking is simple and reliable.
