- Commodity name: KYN28-12 high-voltage switchgear
- 产品特点: Metal Clad Design: The cabinet adopts a metal clad structure, which has high mechanical strength and protection level, and can effectively prevent the spread of internal faults. Modular Design: Each functional unit in the cabinet is modularized, which is convenient for installation, maintenance and expansion. High Reliability: Advanced vacuum circuit breakers are used, which have high breaking capacity and long electrical life. High Safety: It has complete "five-prevention" functions (preventing mis-separation and mis-closing of circuit breakers, preventing on-load separation and closing of isolating switches, preventing live grounding, preventing closing with grounding wire, and preventing entry into live compartments), ensuring operational safety. Intelligence: An intelligent monitoring system can be equipped to realize remote monitoring, fault diagnosis and data acquisition.
The KYN28-12 high-voltage switchgear is a metal-clad, withdrawable switchgear primarily used in 3.6-12kV three-phase AC 50Hz power systems. It serves as distribution equipment in power plants, substations, and industrial and mining enterprises, accepting and distributing electrical energy, and controlling, protecting, and monitoring circuits.
