The KYN61-40.5 type armored removable AC metal-enclosed switchgear (hereinafter referred to as the switchgear) is a three-phase AC 50Hz, rated voltage 40.5kV indoor complete distribution device. It is used in power plants, substations, and industrial and mining enterprises to receive and distribute electric energy, providing control, protection, and monitoring functions for the circuit, and can also be used in places with frequent control operations.

Product Advantages:

Optimized busbar compartment with increased space, meeting the air clearance requirement of 320mm, providing a larger insulation margin.

Self-developed four-linkage shutter mechanism, fully meeting the requirement of 3,000 maintenance-free mechanical life cycles.

The switchgear features reasonable structural arrangement, electric field optimization, and component selection, achieving an overall partial discharge of less than 100pC (test voltage: 1.1Ur).

Optimized grounding switch interlocking mechanism, lowering the operating shaft of the grounding switch to increase the distance from the shaft to the copper bar, meeting insulation distance requirements.

The connections between the main switch, the handcart, and the switchgear door all adopt mandatory mechanical interlocking methods, meeting the "five-proof" requirements. Fully enclosed and unaffected by environmental conditions, it is moisture-proof, dust-proof, and pollution-resistant, with suitability for altitudes up to 3,000m.
