Abstract
The utility model relates to an isolation switch, and provides an isolation switch drain wire. The isolation switch drain wire comprises a disconnecting link insulation support column, a disconnecting link contact handle, and an aluminium flat cable, wherein a disconnecting link rotation shaft is disposed in the disconnecting link insulation support column, the disconnecting link contact handle is disposed at a top part of the disconnecting link rotation shaft, the aluminium flat cable is connected with the disconnecting link rotation shaft through a crimping connection manner, and a drain flexible connection flat cable is disposed between the aluminium flat cable and the disconnecting link contact handle. In the isolation switch drain wire, the drain flexible connection flat cable is added on the disconnecting link contact handle and the aluminium flat cable of the isolation switch, so that the part is short circuited, thus oxidation and resistance increase due to long-time rest are avoided, and local deterioration and over high temperature caused by the oxidation and resistance increase are avoided; and the current guiding flexible connection flat cable plays a role in secondary protection, so that no influence is caused in the rotation process of the disconnecting link contact handle.
Description
Technical field
The utility model relates to a kind of isolating switch, is specifically related to a kind of isolating switch drainage thread.
Background technology
Isolating switch is in High-Voltage Electrical Appliances, to use maximum a kind of electrical equipment, is mainly used to by needing the part having a power failure to isolate reliably with live part in high voltage distribution installation, to guarantee the safety of service work." isolating switch operation maintenance relevant regulations " requires: GW4-15 type isolating switch operating temperature should be no more than permissible value 70 C, if more than 70 ℃, should stop transport.
In maintenance repair work, find, often there is contact overload heating situation in 35kV high-voltage isolating switches in transformer substation, when serious, even occurs that contact burns phenomenon.For this situation, to discuss and analyze and find with other 35kV substation isolating-switch overhaul data contrasts, substation isolating-switch maintenance number of times is apparently higher than other transformer stations, and there is serious potential safety hazard in substation isolating-switch running status.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of isolating switch drainage thread that can avoid disconnecting link to touch handle and aluminum steel discharge heat is provided.
For achieving the above object, the technical scheme of taking is:
A kind of isolating switch drainage thread, comprise that disconnecting link insulation column, disconnecting link touch handle and aluminum steel row, in disconnecting link insulation column, be provided with disconnecting link rotating shaft, the tactile handle of disconnecting link is arranged on the top of disconnecting link rotating shaft, aluminum steel row be connected by crimping mode with disconnecting link rotating shaft, between described aluminum steel row and the tactile handle of disconnecting link, is provided with drainage flexible connecting line row.
Described drainage flexible connecting line row is for adopting the thread flexible connecting line row of copper.
Described aluminum steel row and disconnecting link touch between handle and scribble conductive paste.
Adopt technique scheme, obtained beneficial effect is:
The utility model is touched on handle and aluminum steel row and is added drainage flexible connecting line row by the disconnecting link at isolating switch; make to carry out short circuit herein; with oxidation and the electric increase of organizing avoiding causing because of being failure to actuate for a long time; and then cause local deteriorated; cause excess Temperature; the flexible connecting line of drainage has simultaneously queued the effect of second protection, touches in handle rotary course and can not impact at disconnecting link.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Sequence number in figure: 1 is that disconnecting link insulation column, 2 is arranged, 5 is disconnecting link rotating shaft for drainage flexible connecting line for aluminum steel row, 4 for disconnecting link touches handle, 3.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Referring to Fig. 1, a kind of isolating switch drainage thread, comprise that disconnecting link insulation column 1, disconnecting link touch handle 2 and aluminum steel row 3, in disconnecting link insulation column 1, be provided with disconnecting link rotating shaft 5, the tactile handle 2 of disconnecting link is arranged on the top of disconnecting link rotating shaft 5, aluminum steel row 3 is connected by crimping mode with disconnecting link rotating shaft 5, between described aluminum steel row 3 and the tactile handle 2 of disconnecting link, be provided with drainage flexible connecting line row 4, described drainage flexible connecting line row 4 is for adopting the thread flexible connecting line row of copper, described aluminum steel row 3 and disconnecting link touch between handle 2 and scribble conductive paste, to increase its electric conductivity.
The utility model is touched on handle and aluminum steel row and is added drainage flexible connecting line row by the disconnecting link at isolating switch; make to carry out short circuit herein; with oxidation and the electric increase of organizing avoiding causing because of being failure to actuate for a long time; and then cause local deteriorated; cause excess Temperature; the flexible connecting line of drainage has simultaneously queued the effect of second protection, touches in handle rotary course and can not impact at disconnecting link.
