Indoor High Voltage Grounding Switch

main application

JNI5-D-12-7.2/31.5, JN17-D-12-7.2/40,50 series Indoor High Voltage Grounding Switch (hereinafter referred to as grounding switch) is a new type of grounding switch designed and developed by our company according to the market needs. It is suitable for indoor 3~24KV three-phase AC 50 (60) Hz power system and various types of high voltage switchgear, and can also be used as system grounding during the maintenance of high voltage electrical equipment. And can be used in an unattended and intelligent substation. The product meets the national standard GB1985-2004 "AC high voltage isolation switch and grounding switch" and IEC6227-102-2002. The grounding switch structure is simple and compact, light weight, flexible operation, convenient installation, good dynamic and thermal stability, and reliable electric operation, keep the original middle type switch cabinet chain unchanged, has obtained the national patent. Because the grounding switch is electric operation, the manual operation chain on the middle cabinet is consistent with the original style, but some parts have been modified. Be sure to use the supporting chain parts, otherwise the motor of the electric grounding switch will be burned. If the back door of the middle cabinet needs to be linked with the electric grounding switch, it is also necessary to use the back door interlocking mechanism produced by the company's patented technology, and equipped with the stroke switch. When the back door is not closed, cut off the operating power supply of the electric grounding switch, so as to avoid the motor damage caused by the misoperation of the electric grounding switch. When conducting the electrical linkage with the electric grounding switch, be sure to use the auxiliary contact of the associated coupling element to disconnect the operating power supply of the electric grounding switch and realize the electrical linkage.To ensure the reliability of the electrical chain.
