Outline

XGN15-12 box-type fixed AC metal-enclosed switchgear (hereinafter referred to as ring-network cabinet) is a new type of highvoltage electrical product that we have designed and developed successfully in accordance with the requirements of domestic rural power and urban network transformation after introducing foreign excellent technology. All technical performance indicators comply with IEC62271-2003 and GB3906 standards.

The main switch, operating mechanism and components of the ring-network cabinet adopt the SFL-12/24 switchgear manufactured by ABB original parts or imported parts, and can also be equipped with ABB original HAD/US SF6 according to user needs. Circuit breaker or vacuum circuit breaker. Its operation mode is divided into dynamic and electric.

The cabinet body is riveted after being processed by CNC machine tool, with the protection grade of IP3X, and has reliable mechanical interlocking and anti-misoperation functions. This product is characterized by small size, light weight, beautiful appearance, simple operation, long service life, high parameters, no pollution and less maintenance.

XGN15-12 box-type fixed AC metal-enclosed switchgear is applicable to the AC 50Hz, 12kV power network as the acceptance and distribution of electric energy. The main switch in the cabinet is SF6 switch.

operation

For the switchgear equipped with load switch, use the special operating handle to operate on the front of the switchgear.

The front of the operating mechanism has upper and lower operating holes, the upper part is the grounding switch operating hole, and the lower part is the load switch operating hole. During operation, clockwise rotation of the handle is the closing direction of the switch, and counterclockwise rotation is the opening direction of the switch. Electric opening and closing devices can also be installed for remote control. (Note: sometimes the load switch is not equipped with a grounding switch, and the operating hole of the grounding switch is used for unlocking the cabinet door).

For the switchgear equipped with combined electrical appliances, the operation sequence is the same as above, except that the manual opening button is used for the opening operation of the load switch. The lower grounding switch additionally set in the combined electrical cabinet is opened and closed with the upper grounding switch through the connecting rod.

When closing, release the residual small current on the lower fuse base to improve the safety when replacing the breaker.
