Product overview
GTXGN-12 Solid insulated ring switchgear is a new generation of environmental protection composite insulated ring switchgear developed by our company. It is a fully sealed power supply unit, all live parts and switches are fully sealed in an epoxy resin shell, and there is no SF6 gas in the shell. The whole switching device is not affected by the external environment, ensuring the reliability of operation and personal safety, and achieving maintenance-free.
Solid insulated ring cabinet consists of three kinds of switches, that is, V unit (circuit breaker unit), C unit (load switch unit), F unit (combined electrical unit), each unit can be used separately and can be freely expanded, its structure is divided into intelligent control instrument room, operating mechanism and a part, instrument room can be equipped with microcomputer protection (controller), The primary part adopts the APG automatic gel process, the isolation switch and the arc extinguishing chamber are completely sealed in epoxy resin, and the special joint is connected with the bus bar. The arc extinguishing chamber adopts special copper-chromium contact material, only longitudinal magnetic field contact, and complete one-time sealing process. The breaking short-circuit current capacity and stability, electrical life, temperature rise and insulation level of the 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 one-time sealing process). The operating mechanism adopts the elastic operating mechanism integrated with the switch, that is, the isolation switch and the main switch elastic operating mechanism are a whole, which can facilitate the realization of interlock, and the mechanism has fewer parts, reduces the unnecessary transmission link and has high reliability, and can achieve electric operation according to the needs of users.
Solid insulated fully enclosed switchgear: It is a solid insulating material as the main insulating medium and conductive connection, isolation switch, ground switch, main bus, branch bus and other main electrical circuit after a single or combined with solid insulating medium encapsulation into one or several modules with a certain function, can be recombined or expanded with full insulation and full sealing performance.
Ring network unit is suitable for 12KV, 50Hz three-phase AC distribution system, for ring network power supply or terminal power supply. Ring network units can be installed in industrial and mining enterprises, residential areas. Distribution systems for schools, parks, etc., can also be installed in compact box-type substations for the control and protection of distribution transformers. Therefore, both indoor and outdoor ring network units can realize distribution automation.
