Product Overview:
The GTXGN-12 solid insulated ring main unit switchgear is a new generation of environmentally friendly composite insulated ring main unit independently developed by our company. It is a fully sealed power supply unit, in which all live parts and switches are fully sealed within an epoxy plastic shell, and there is no SF6 gas inside the shell. The entire switch device is not affected by external environment, ensuring operational reliability and personal safety, and achieving maintenance free operation.
GTXGN port -12 solid insulation ring network switchgear consists of three types of switches, 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 primary part uses APG automatic gel process to completely seal the disconnector and arc extinguishing chamber in epoxy resin, and there are special connectors connected to the bus. The arc extinguishing chamber adopts specialized copper chromium contact material, R-type longitudinal magnetic field contact, and complete one-time sealing process. The ability and stability of the arc extinguishing chamber to break short-circuit current, electrical life, temperature rise, and insulation level have been significantly improved compared to previous arc extinguishing chambers (copper aluminum contact material, cup-shaped 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 electrically operated according to user needs.
GTXGN-12 Solid 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 GTXGN-12 solid insulated ring network switchgear is suitable for 12kV, 50HZ three-phase AC distribution systems, used for ring network power supply or terminal power supply. The ring network unit can be installed in the power distribution system of industrial and enterprises, residential areas, schools, parks, etc. It can also be installed in compact box type substations for the control and protection of distribution transformers. So both indoor and outdoor ring network units can achieve distribution automation.
