Description
Technical field
The utility model relates to a kind of to the monitoring apparatus on cable transmission node, specifically cable node monitors protection mechanism.
Background technology
The quick protection of transmission line malfunction with accurately locate, can not get good solution for a long time, directly affect the service restoration time of faulty line, also bring white elephant to circuit operation maintenance personnel.
In order to solve the problem, prior art provides cable fault localization method, and whole piece cable arranges the monitoring point distributed between multiple grade.If there is line fault, as long as detect voltage and the current situation of each monitoring point respectively, just can deduce abort situation is be between which two monitoring point.The wherein detection means of voltage and electric current, when being cable power-off completely, operating personnel (are needed first by strippings such as the sheathcoat of cable, mica layers by the wire of active type universal meter to monitoring point carried, make the wire being in cable inner out exposed, wire described herein refers to conduction copper cash or other metal wires) detect.
There is following technological deficiency in above-mentioned prior art: 1, each detection all needs to make strip operation, complex operation to the cable of monitoring point; 2, the cable after peeling off also will carry out urgent safe handling (as being wound around insulating tape outward at exposed wire), deals with improperly, also likely causes potential safety hazard.
Utility model content
The utility model is intended to provide a kind of cable node monitors protection mechanism, can avoid strip operation when at every turn detecting, and can carry out insulation isolation to the wire at monitoring point place.
Cable node monitors protection mechanism in this programme, comprises insulating sleeve, conduction backing plate, conducting rod and insulation enclosing cover; Described conduction backing plate is located in insulating sleeve, described insulating sleeve is provided with side direction through hole, one end of described conducting rod is passed described side direction through hole and is electrically connected with conduction backing plate, and the other end of described conducting rod is exposed joint, and this exposed fitting sleeve is located in insulation enclosing cover.
When using the cable node monitors protection mechanism in this programme, need first by strippings such as the sheathcoat of monitoring point place cable, mica layers, the wire making to be in cable inner is exposed out (below by exposed wire out, namely conduction metal wire is referred to as bare wire), then insulating sleeve is enclosed within bare wire, conduction backing plate in insulating sleeve and bare wire are electrically connected, more described conducting rod and insulation enclosing cover are installed.
The utility model is adopted to have following technique effect:
Because bare wire, conduction backing plate and conducting rod are electrically connected successively, so when needing electric current, the magnitude of voltage detecting monitoring point place, only need described insulation enclosing cover to take off, the exposed joint of direct-detection conducting rod; After detection completes, also only need insulation enclosing cover to reset.
Compared with strip operation when at every turn detecting and safe handling, the taking off of the enclosing cover that insulate in this programme operates comparatively simple and easy with installation; When not needing to detect, the bare wire of whole monitoring point by insulating sleeve and insulation enclosing cover the insulation system institute that formed coated, reach the object of isolation of carrying out insulating to the wire at monitoring point place.
Further, described insulating sleeve is provided with circumferential ring groove, and circumferential ring groove is provided with the circumferential band for insulating sleeve described in banding.
In order to increase the strength of joint between insulating sleeve and cable, insulating sleeve being stably positioned on cable, specially circumferential band being set at insulating sleeve, by whole insulating sleeve banding on cable.
Further, also comprise the insulating cylinder be connected with described side direction through hole whorl, the exposed joint that its exposed part relative to insulating cylinder of described conducting rod is namely described.
If exposed joint is longer, the enclosing cover that insulate described in that will have corresponding length, otherwise be difficult to realize coated to exposed joint of insulation enclosing cover.But long insulation enclosing cover, to be difficult to take off and reset, therefore in order to improve the convenience degree of operation, just should reduce the design length of exposed joint, namely reduces its length relative to the exposed part of insulating cylinder of external conducting rod as far as possible.
For this reason, the extended structure of an insulating sleeve is set in described side direction through hole, make conducting rod major part by insulating sleeve and extended structure institute coated, thus reduce the exposed length of conducting rod.The extended structure of described insulating sleeve and described insulating cylinder.
Further, described insulation enclosing cover comprises the bar shaped bar that rubber bush and insulating material are made, and the two-port of rubber bush is uncovered, and exposed fitting sleeve is located in rubber bush, and described bar shaped bar is plugged on described exposed joint by the uncovered of rubber bush.
If detected at every turn, all need whole insulation enclosing cover take off and reset, can operation easier be improved; Now insulation enclosing cover is divided into rubber bush and bar shaped bar, only needs to take off and reset bar bar during each operation, reduce further operation easier.
