Keywords:
The KYN28-12(GZS1) indoor metal-clad withdrawable switchgear (hereinafter referred to as the switchgear) is a complete set of distribution equipment designed for three-phase AC systems with a frequency of 50 Hz and rated voltages ranging from 3.6 to 12 kV, intended for single-busbar and single-busbar sectionalized systems. It is primarily used in power plants, substations, distribution and transformation centers of industrial and mining enterprises, as well as in large high-voltage motor starting devices. The switchgear serves to receive and distribute electrical energy, and also provides control, protection, and monitoring functions for electrical circuits. This switchgear complies with standards including IEC 298, GB 3906, and DL/T 404. It features five key interlocks—preventing accidental operation of circuit breakers, preventing the insertion or withdrawal of trolleys under load, preventing closing of the grounding switch while live, preventing energization when the grounding switch is in the grounded position, and preventing unauthorized entry into live compartments—making it a highly reliable and superior-performing distribution device.
