Abstract
The utility model discloses a parallel capacitor set discharge device and applies to the electric power system maintenance field. The parallel capacitor set discharge device comprises an insulation rod. One end of the insulation rod is provided with an insulation support. A discharge element is fixed under the insulation support. Discharge taps capable of being connected with a parallel capacitor discharge end are arranged under the discharge element. The other end of the discharge element is connected with a grounding wire. A high-voltage alarm device is fixed on the insulation support and connected with the grounding wire and the discharge taps of the discharge element. The parallel capacitor set discharge device can reduce discharge current, enable the discharge to be free of electric arc and discharge sound, and cause no influence onto surrounding operation equipment.
Description
Technical field
The utility model relates to a kind of electric discharge device of the Shunt Capacitor Unit for 10kV or 35kV electric pressure, belongs to the maintenance field of electric power system.
Background technology
In the 10kV of electric power system or the transformer station of 35kV electric pressure, be all provided with Shunt Capacitor Unit.In the time processing the defect of Shunt Capacitor Unit of 10kV or 35kV electric pressure, need first discharge to Shunt Capacitor Unit, when electric discharge staff normally property-line directly Shunt Capacitor Unit ground connection is discharged.But owing to having a large amount of residual charges on each capacitor, directly over the ground in discharge process, there are a lot of unsafe factors at ground wire, as: electric arc, discharging sound easily produced more greatly, easily staff is caused to personal injury etc.
Utility model content
The utility model technical issues that need to address are to provide a kind of discharging current that reduces, and there is no the special electric discharge device of shunt capacitor of electric arc and discharging sound while making to discharge.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Shunt Capacitor Unit electric discharge device, comprise an insulating bar, in one end of insulating bar, one insulating support is set, below insulating support, fix an arresting element, below arresting element, be provided with the electric discharge tap that can contact with shunt capacitor discharge end, the other end of arresting element is connected with earth connection; On insulating support, fix an alarm for high voltage device, alarm for high voltage device is connected with the electric discharge tap of earth connection, arresting element.
Further improvement of the utility model is: the other end of described insulating bar is provided with handle.
Further improvement of the utility model is: described arresting element is made up of through series and parallel connections some resistance, and the electric discharge tap setting of arresting element has two, respectively the shunt capacitor of corresponding 10kV and 35kV.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model is the special electric discharge device for 10～35kV shunt capacitor, this electric discharge device has the effect of pressure release and current limliting, when to capacitor discharge, within arresting element can be limited in 10mA by discharging current, while making to discharge, produce very little electric arc, negligible, can guarantee defect elimination personnel's safety.In addition, while utilizing this device to capacitor discharge, there is no electric arc and discharging sound, so near the equipment operation can not affecting; This device can also utilize alarm for high voltage device to connect directly electrical verification after capacitor, the injury that can avoid residual charge to cause personnel in the time that earth connection is earth-free; When insufficient to capacitor discharge or when arresting element damages, install self and can send warning, played protection staff's effect.
