High voltage electrical panel for substation model KYN28-12
KYN28A- 12 (GZS1) type armored removable AC metal- enclosed switchgear (hereinafter referred to as "switchgear") is suitable for three- phase AC 50Hz power system for receiving and distributing power and controlling, protecting and monitoring of the circuit in real time.
The product is in line with IEC600271 "3-35kV AC metal enclosed switchgear", common technical requirements of high voltage switchgear and control equipment standard", IEC62271 "AC metal-enclosed switchgear and control equipment with rated voltage 1 kV above 52kV and below".
KYN28-12 removable AC metal-clad switchgear (short for panel as below) is a new product. It will be a substitute for old fashioned metal-enclosed switchgear, such as KYN-12, JYN-12, GFC-12, etc. The panel applies to 3.6~12kV 3 phase AC 50Hz network for receiving and distributing power energy and also for control, monitor and protection. It accords with standard of IEC62271-200, IEC60694, GB3906.
The newly introduced and developed large current and high breaking switchgear can also be used as a high- voltage generator export.
1. The box of the KYN28A air insulated metal clad switchgear is made of aluminum-zinc coated steel sheet, so it is light, strong and beautiful.
2. The electric clearance is larger than 125mm, and the composite insulation electric clearance is larger than 30 mm.
3. Central-positioned circuit breaker.
4. Perfect integrated interlocking mechanism
5. Completed primary systematic diagram, more than 80 main circuit schemes
