HXGN口-12
Overview：
HXGN口-12 type vacuum ring main unit (box) is suitable for the power distribution system of Industrial & Mining enterprises, Residential blocks, High-rise buildings, and Schools. It is used as the indoor AC voltage 10kV and frequency 50Hz RMU the power supply unit and terminal power distribution equipment. It can break or close the rated load current and no-load current of transformers and can break or close the capacitive current of the overhead line, cable line, or capacitor bank within a certain distance. The load switch-fuse combination electrical cabinet can break the rated short-circuit current at one time. It is used in the power system for the protection of power distribution equipment, the distribution of electric energy, and the protection and control of transformers.

The busbar chamber is closed by metal, and the busbar is connected through a wall bushing. According to requirements, a completely isolated instrument chamber can be set in the front of the busbar chamber, for the secondary equipment installation. The switch chamber mainly installs primary equipment and for cable connection. The cabinet door and the switch realize the Five-Anti mechanical interlock, which is simple and reliable. An observation window on the door to facilitate observing the isolation gap and inspecting the operating state.
  3. This high-voltage load switch cabinet is divided into a cable chamber, a busbar chamber, and an instrument chamber, and the front door is equipped with a locking device. Only when the high-voltage electricity is disconnected and the grounding knife is closed can the front and rear doors be opened. It has reliable " Five-Anti " functions.
