Box-type Fixed AC Metal-enclosed Switchgear

  • XGN15-12

Availability:

The XGN15-12 unitized AC metal-enclosed ring main switchgear (hereinafter referred to as the ring main unit) is a high-voltage electrical product independently designed and successfully developed by us after introducing foreign technologies and in accordance with the requirements of domestic rural and urban power grid transformation. All technical performance indicators fully comply with the standards of IEC62271-200:2003 and GB3906.


The main switch, operating mechanism and components of the ring main unit use original parts from ABB or the SFL-12/24 type switchgear assembled in China with imported parts. It can also be equipped with the original HAD/US type SF6 circuit breaker or the VD4-S type vacuum circuit breaker from ABB according to user needs. Its operating modes are divided into manual and electric.


The cabinet is riveted after being processed by a numerical control machine tool, with a protection level of IP3X, and has reliable mechanical interlocking and anti-misoperation functions. This product has extremely significant features such as small size, light weight, beautiful appearance, simple operation, long service life, high parameters, no pollution and less maintenance.


The XGN15-12 unitized AC metal-enclosed ring main switchgear is suitable for use in AC power networks with a frequency of 50Hz and a voltage of 12kV for the reception and distribution of electric energy. The main switch in the cabinet is an SF6 switch.


For switchgear equipped with a load switch, operate it on the front of the switchgear with a special operating handle. There are two operating holes, upper and lower, on the front of the operating mechanism. The upper one is for the earthing switch operation, and the lower one is for the load switch operation. During operation, turning the handle clockwise is the closing direction of the switch, and turning it counter - clockwise is the opening direction of the switch. An electric opening and closing device can also be installed for remote control operation. (Note: Sometimes the load switch is not equipped with an earthing switch, and the earthing switch operating hole is used to unlock the cabinet door).

For switchgear equipped with a combined electrical apparatus, except that the opening operation of the load switch uses a manual opening button, other operating sequences are the same as above. The lower earthing switch additionally installed in the combined electrical apparatus cabinet is connected with the upper earthing switch through a connecting rod and operates synchronously. When closing, the residual small current on the lower fuse base is released to improve the safety when replacing the fuse.
