overview

GN-GTXGN-12 solid fully enclosed and fully insulated ring main unit switchgear is a new generation of environmentally friendly composite insulated ring main unit. It is mainly composed of three components, namely, unit V (circuit breaker unit), unit C (load switch unit) and unit F (combined electrical apparatus 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). The mechanism is a special spring operating mechanism. The primary part uses APG automatic gel process to completely seal the disconnector and arcing chamber in epoxy resin, and has a special connector to connect with the bus. The design switch of the arc extinguishing chamber uses specialized copper contact materials, R-type longitudinal magnetic field contacts, and a complete one-time sealing process. The arc extinguishing chamber has significantly improved short-circuit current breaking ability and stability, electrical life, temperature rise, and insulation level compared to previous arc extinguishing chambers (copper aluminum contact materials, radial longitudinal magnetic field contact structure, and incomplete one-time sealing process). The operating mechanism adopts a spring operated mechanism that is integrated with the switch, that is, the isolation switch and the main switch spring operated mechanism are integrated as a whole, which can easily achieve interlocking, and the mechanism has fewer parts, reducing unnecessary transmission links, high reliability, and can be equipped with electric operation according to user needs.

Solid state fully enclosed and insulated ring network switchgear: It is a module with full insulation and sealing performance that uses solid insulation materials as the main insulation medium and conductive connections, isolating switches, grounding switches, main busbars, branch busbars, and other main electrical circuits that are single or combined and encapsulated with solid insulation medium to form one or several modules with certain functions, which can be combined or expanded again. The three station mechanism adopts a mid spring design, which has the function of breaking and closing load current, and can also achieve manual and electric operation.
