Product Description

 

HXGN œ - 12 box type fixed AC metal-enclosed ring network switchgear (hereinafter referred to as "ring network cabinet/switchgear") is suitable for power distribution systems in areas such as industrial and mining enterprises, residential areas, high-rise buildings, schools, and parks. It is used as an indoor AC three-phase 12kV, 50Hz ring network power supply unit and terminal power distribution equipment. It can disconnect or close the rated load current and transformer no-load current and can disconnect or close the overhead line, cable line, or capacitive current at a certain distance. The load switch fuse combination cabinet can disconnect the rated short-circuit current at one time. In the power system, as the protection of distribution equipment and the distribution and control of electric energy, it has a perfect "five prevention" locking function.

The switchgear complies with the requirements of national standard GB3906 (3-35kv AC metal-enclosed switchgear), GB /T11022 (common technical requirements for standards of high voltage switchgear and control equipment), National Standard IEC 60298 (AC metal-enclosed switchgear and control equipment with rated voltage above 1kV and below 52kV), and IEC 60694 (common terms for high voltage switchgear and control equipment).

HXGN œ - 12 ring network structure is composed of 8MF steel locally welded and bolted. It is mainly equipped with an fln36 sulfur HEXAOXIDE load switch and FZN12 / FZN21 / FZN25 two-position vacuum load switch. The load switch and fuse with the impactor are used as combined appliances. The ring main cabinet can be flexibly equipped with CT, Pt, and ZnO arresters. A removable movable cover plate is installed at the bottom of the cabinet to facilitate cable incoming. For overhead incoming lines, another bus channel can be installed according to the user's requirements.
