Description

Feature

Parameter

The KRSIS-12V solid insulation switchgear adopts a modular structure design, which allows for arbitrary combination and expansion of the switchgear, making it convenient for maintenance and repair. Fully insulated, fully sealed, and maintenance free, all live parts are fully insulated. Adopting fully insulated busbar, longitudinally arranged, convenient and reliable connection. Equipped with an independent low-voltage room, which can be equipped with microcomputer protection and various meters, there is no need to install a low-voltage compartment on the top of the cabinet, making the arrangement of the switchgear more beautiful and compact. Equipped with an independent low-voltage room, which can be equipped with microcomputer protection and various meters, there is no need to install a low-voltage compartment on the top of the cabinet, making the arrangement of the switchgear more beautiful and compact.

Product technical features:
1. Adopting heat shrink insulation materials and epoxy coating insulation process, optimizing electrode shape, compact cabinet structure, and reducing floor area;
2. The switchgear cabinet body is made of high-quality cold-rolled steel, which is formed by CNC sheet metal processing and connected by high-strength bolts and nuts and rivet nuts. The surface of the components is sprayed with plastic or galvanized technology;
3. It can be matched with domestic ZN85-40.5 vacuum circuit breakers and foreign SF1, SF2, and FP system sulfur hexafluoride circuit breakers to meet the needs of different users;
4. Each functional compartment of the switchgear is sealed with metal plates and equipped with independent pressure release channels;
5. Circuit breakers, grounding switches, and other operations can be carried out when the switchgear is closed, achieving door closing operation;
6. The structural adaptability of the switchgear is strong, with over 198 main wiring schemes that can meet the needs of different users;
7. There is a mechanical interlocking device between the handcart, circuit breaker, grounding switch, and rear cabinet door to prevent misoperation. The "five prevention" functions are complete, safe and reliable
