Abstract
Manual discharging device of portable bulk capacitor is an apparatus for the electrician to repair an electric appliance, which has overcome the shortcomings of existing technology, and which is composed by connecting a scalable insulation pole, a discharge head, a discharge leading ground line, a grounding clamp, copper screws, copper screw caps, washers, spring washers, and copper contacts. The discharge head is at the top of the scalable insulation pole, and the washers and spring washers on the discharge head are set on the copper screws, while the copper screw caps are fixed at the top of the copper screws via screws, and the copper contacts are fixed on the discharge head; one end of the discharge leading ground line is fixed on the discharge head, anthor end of it is conneced to the grounding clamp; when used, the scalable insulation pole will be opened, and discharge the copper contacts on the discharge head will ocnnect with the capacitor, then the grounding clamp plugs into the underground to discharge until the charge is exhausted, then receiving the scalable insulation pole.
Description
One, technical field: the utility model relates to a kind of utensil that a kind of electrician overhauls electrical equipment, especially portable capacitor in bulk manual discharge device.
Two, background technology: when capacitor disconnects from power supply, the two poles of the earth still are in the energy storage state, 30 seconds are through discharge resistance discharge, voltage is reduced to below the 65v, puts endless but still have the part residual load, if it should be noted the inner broken string of capacitor especially, fuse failure (accounting for capacitor fault 11.5%) or lead-in wire loose contact, individual capacitors still stores electric charge, at this moment if staff's mistake is just bumped and might be shocked by electricity or electric burn, jeopardizes staff's life when serious.Be contained on the room column jacket or the capacitor of overhead layout, because it is higher that the place is installed, in work such as capacitor interruption maintenance, cleaning, inspection or replacing insurances, before whole group capacitor hangs temporary ground wire, must carry out once or the several manual discharge, after treating that residual charge drains, just can hang temporary ground wire and start working.According to the power system accident statistics, because of the human casualty accident of ignoring or in accordance with regulations the capacitor manual discharge is not caused happens occasionally.Over the years, because of capacitor work all uses the temporary ground wire direct amplifier system by only discharge, because the temporary grounding line length is not enough, on-the-spot ground connection bolt quantity, position are improper, the capacitor of overhead especially layout is subjected to the restriction of installing space and ascend operation with the temporary ground wire discharge, the operations staff is brought a lot of inconvenience, and constitute security threat.Relatively heavier with temporary ground wire as the manual discharge device.
Three, summary of the invention: the purpose of this utility model provides portable capacitor in bulk manual discharge device, it has overcome the deficiencies in the prior art, the purpose of this utility model is to realize like this, it is by scalable insulating bar, the discharge head, the discharge downlead, the ground connection clamp, brass screws, the bronze gong cap, packing ring, spring washer, the red copper contact head is formed by connecting, there is the discharge head on the top of scalable insulating bar, packing ring on the discharge head, spring washer is enclosed within on the brass screws, the bronze gong cap is fixed on the top of brass screws by silk, and the red copper contact head is fixed on the discharge head; Discharge downlead one end is fixed on the discharge head, and its other end is connecting the ground connection clamp.
During use, scalable insulating bar is drawn back, the red copper contact head on the discharge head contacts with capacitor, and the ground connection clamp is inserted into underground the discharge, when treating that electric charge drains, shrinks insulating bar again.
This device is easy, quick, flexible, reliable, easy to store, convenient disassembly, portable practicality, has alleviated labour intensity, saving of labor, has saved time, high efficiency.
Four, description of drawings: Fig. 1 is the structural representation of portable capacitor in bulk manual discharge device: among the figure 1, scalable insulating bar 2, discharge head 3, discharge downlead 4, ground connection clamp 5, brass screws 6, bronze gong cap 7, packing ring 8, spring washer 9, red copper contact head
Five, embodiment: in Fig. 1, there is discharge head 2 on the top of scalable insulating bar 1, packing ring 7, the spring washer 8 of discharge on the head 2 is enclosed within on the brass screws 5, and bronze gong cap 6 is fixed on the top of brass screws 5 by silk, and red copper contact head 9 is fixed on the discharge head 2; Discharge downlead 3 one ends are fixed on the discharge head 2, and its other end is connecting ground connection clamp 4.
