Product Description
Product Description
Equipped with enhanced safety features, including automatic overload protection, ensuring reliable and safe power transmission.
KYN type metal-clad and metal-enclosed withdrawable switchgear is one kind of indoor power distribution device that suitable for three-phase AC 50Hz, rated voltage 10~35KV, working current to 4000A. It is mainly used to receive and distribute electric energy for power plants, small and medium-sized generators for power transmission, substations, industrial and mining enterprises, institutions, etc., which plays the functions of control, protection and detection of circuits, and can also be used to control places with frequent operations.

Main Characteristics
Qinghao switchgear meets the requirements of GB/T11022, GB/T3906 and IEC60298 related standards. It has the interlocking device function to prevent below:
1. pushing and pulling circuit breaker truck when on loading.
2. miss opening and closing circuit breakers.
3. closing the circuit breaker when the grounding switch is in the closed position.
4. miss entry into the live compartment,
5. miss closing the grounding switch when it is live.
Advantages
1. With the function of "five prevention" interlocking device, the operation is safe and reliable.
2. Optional vacuum circuit breaker, load switch and disconnector, etc.
3. According to the use, it can be divided into circuit breaker handcart, voltage transformer handcar, metering handcar, isolation handcar, etc., and the handcart for the same purpose has good interchangeability.
4. The circuit breaker room and the cable room can be equipped with heaters separately to prevent condensation and corrosion.
5. The enclosure protection level of the switchgear reaches IP4X, and the protection level between compartments and when the door of the circuit breaker room is opened, the protection level is IP2X.
6. The door panels and sealing plates around the switchgear are made of 2mm cold-rolled steel plates, which are strong and durable.
Applications
1. Power plants, power transmitting of middle and small size generators.
2. Distribution of industrial and mine enterprises.
3. Electricity receiving and transmitting of secondary substations.
4. Starting of motors.
Service Environment
1. Ambient temperature: -30°C to +45°C
2. Altitude: ≤1000 meters.
3. Max. air relative humidity90%(±25ºC);
4. Max. Ground ramp degree 3°;
5. The earthquake: the horizontal acceleration≤0.3m/s2 , the vertical acceleration≤0.15m/s2
6. The installation site shall be free from explosion danger, fire, filthy material, chemical corrosion and violent vibration;
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
