HL-XHD arc suppression coil and grounding sleeve device
- Brand: Shanghai Hong Li electric
- Type: HL-XHD arc suppression coil and grounding sleeve device
The 10KV arc suppression coil and the grounding turn into a suit of Shanghai macrocalendar electric professional production, and the three kinds of adjustment mode of partial magnetic switch type adjustable capacity type are more extensive.
The 10KV arc suppression coil and the earthing turn into three kinds of adjusting modes, which are partial magnetic, turn - to - turn, and adjustable - style of Shanghai macro calendar. Shanghai Hong Li Electric Co. Ltd. for power system neutral grounding via arc suppression coil, developed the HL- XHD intelligent arc suppression coil grounding device, mainly used for 6KV, 10KV and 35KV in power grid, Petersen coil grounding mode; compensating capacitive current, keep on setting parameters within the scope of eliminating power grid system overvoltage and resonance overvoltage in power grid, automatic alarm grounding fault, remote output port for communication with pc.. The device is characterized by the advantages of fast response, high precision, and the solution of the dead machine. It is the preferred grounding device for the medium voltage distribution network.

Effect of arc suppression coil on arc suppression coil of arc suppression coil; principle of bias arc suppression coil to compensate arc suppression coil for neutral point of power grid.
1, to automatically eliminate the instantaneous single-phase grounding fault of the power grid
2, when a permanent (metal) when the single-phase grounding fault, there are two options: the line selection device or a microcomputer protective grounding fault detection circuit, acting on the trip; also can make the grid faults in a certain period of time, the scheduling department load transfer delay tripping fault line, the power grid has high operation reliability.
