MRGXGN-12 Solid fully insulated closed ring switchgear

Summary
MRGXGN-12 solid insulation ring network switchgear is a new generation of environment-friendly composite insulation ring network cabinet produced by our company. It is a fully sealed power supply unit. All live parts and switches are fully sealed in an epoxy plastic housing without SF6 gas. The whole switch device is not affected by the external environment, ensuring operation reliability and personal safety, and realizing maintenance free.The solid insulated ring network cabinet is composed of three types of switches, namely, V unit (circuit breaker unit), C unit (load switch unit) and F unit (combined electrical unit). Each unit can be used independently or expanded freely. Its structure is divided into intelligent control instrument room, operating mechanism and primary part. The instrument room can be equipped with microcomputer protection (controller), and the primary part adopts APG automatic gel process, Isolating switch and arc extinguishing chamber shall be completely sealed in epoxy resin, and special joint shall be connected with bus. The arc extinguishing chamber adopts special copper chromium contact material, R type longitudinal magnetic field contact, and complete primary sealing and discharging process. The ability and stability of breaking short circuit current, electrical life, temperature rise, and insulation level of this arc extinguishing chamber are significantly improved compared with the previous arc extinguishing chamber (copper aluminum contact material, cup shaped longitudinal magnetic field contact structure, and incomplete primary sealing and discharging process). The operating mechanism adopts a spring operating mechanism that is integrated with the switch, that is, the isolating switch and the main switch spring operating mechanism are integrated, which can facilitate interlocking. Besides, there are few parts of the mechanism, which reduces unnecessary transmission links, has high reliability, and can realize electric operation according to user needs.Solid insulated totally enclosed switchgear: it is a kind of module with full insulation and sealing performance that is encapsulated by solid insulating medium after single or combined main electrical circuits such as solid insulating material as main insulating medium and conductive connection, disconnector, grounding switch, main bus, branch bus, etc. are used to wrap and encapsulate into one or several modules with full insulation and sealing performance that have certain functions and can be combined or expanded again. The loop network unit is applicable to the 12kV, 50Hz three-phase AC power distribution system for loop network power supply.....
