Product overview and scope of application:
Xgn15a-12zf (R) box type (fixed) metal enclosed ring network switchgear (hereinafter referred to as ring network cabinet) is a new type of high-voltage switchgear produced for the transformation and construction of urban power grid. It is used for breaking load current and short-circuit current, closing short-circuit and closing short-circuit current in power supply system.
The ring main cabinet is equipped with a vacuum load switch, and the operating mechanism is a spring operating mechanism, which can be operated manually or electrically. The grounding switch and disconnector are equipped with a manual operating mechanism. This ring main cabinet has strong integrity, small volume, no combustion and explosion hazards, and has a reliable "five prevention" function.
Ring network cabinet is suitable for 10kV and 50Hz AC power distribution system, and is widely used in urban power grid construction and transformation projects, industrial and mining enterprises, high-rise buildings and public facilities. As a ring network power supply unit and terminal equipment, it plays the role of power distribution, control and protection of electrical equipment, and can also be installed in box type substation. The ring main unit complies with the relevant provisions of IEC high voltage AC load switch capacitor breaker combination apparatus and gb3906-91 3-35kv AC metal enclosed switchgear.
