Overview

　　HXGNl5A-12 high voltage ring network switchgear is suitable for three-phase AC 12kV, 50HZ power distribution system, widely used in urban network construction and renovation projects, industrial and mining enterprises, high-rise buildings and public facilities, etc. And terminal equipment, which plays the role of power distribution, control and protection of electrical equipment.

　　This product is a new product designed by Xigao Institute for national unified design. It has the characteristics of strong set, small size, light weight, long life, safe and reliable, convenient operation and maintenance, etc. The technical performance of the product conforms to GB3906 and IEC298 standards.

 

　　Characteristics

　　HXGNl5A-12 high voltage ring network switch cabinet is mainly composed of cabinet, load switch （including isolation switch, grounding switch）, operating mechanism, interlocking mechanism and measuring or measuring circuit. Its fuse combination electric appliance scheme can replace the high-capacity circuit breaker cabinet, which is an ideal equipment for urban ring network power supply.

　　The vacuum or compressed air load switch used in the product has an isolation switch, a vacuum switch, a grounding switch and a cabinet door which are composed of switches, and interlocks according to a certain program, which can effectively prevent misoperation and achieve quick integration. Opening operation. According to the user's requirements, the electric mechanism can be configured to operate, and a certain protection relay can also be assembled. The fuse combines the electrical cabinet, the fuse has a striker, and in the case of a short circuit, the striker hits the trip mechanism to achieve a quick break, which can effectively protect the electrical equipment.
