Description
Technical field
This utility model relates to transmission line of electricity technical field, particularly a kind of transmission line of electricity joint excess temperature alarming device.
Background technology
The strain insulator terminal that ultra-high-tension power transmission line uses is in atmospheric environment, because the factors such as humidity, temperature, wind-force, high voltage shock cause terminal to aoxidize, corrode and loosen, terminal resistance increase after Song Donging easily is generated heat, produce superheating phenomenon, along with overheated time lengthening, there is also the situation of circuit fusing breaking out of fire.In traditional terminal, conductive plate is smooth connects, and the less conduction of contact area is not good, and during high voltage power transmission, as there is superheating phenomenon in transmission line of electricity junction in resistance problems.Therefore, find transmission line of electricity joint excess temperature hidden danger the most in advance, fix a breakdown in time, be to ensure that the important topic of transmission line of electricity safe operation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of transmission line of electricity joint excess temperature alarming device, there is the warning sign when transmission line of electricity joint excess temperature glide in metal case and stretch out, fault is got rid of as early as possible to make patrol officer find in time, it is ensured that the feature of transmission line of electricity safe operation.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of transmission line of electricity joint excess temperature alarming device, including the metal case being fastenedly connected with transmission line of electricity joint, warning sign and meltable dielectric rod；Described warning sign can slide up and down in metal case, the left and right on described warning sign top is respectively arranged at two ends with boss, the bottom of metal case is provided with glide outlet and the position-limit mechanism of stop boss downslide of warning sign, and described meltable dielectric rod passes across the through hole on warning sign and is erected on the two side of metal case at both ends.
Improving further of being done this utility model is: the fusion temperature of described meltable dielectric rod is between 50 ° of C-90 ° of C.
The material of described meltable dielectric rod is paraffin.
Also include upright guide rail and heat-conducting plate；Described upright guide rail is symmetrically connected on the inwall of the metal case left and right sides, described heat-conducting plate is symmetrically connected on the inwall of other both sides of metal case, described warning sign can slide between two upright guide rails, and described meltable dielectric rod is through the through hole on warning sign and is erected at both ends on two heat-conducting plates.
Described position-limit mechanism is bolt, and described bolt has two and is separately fixed at the downslide of upright guide rail lower barrier boss.
Also include that stage clip, described stage clip are arranged between the upper cover of metal case and warning sign.
Also including fixing the metal connecting plate being connected with metal case, described metal case is connected on transmission line of electricity joint by metal connecting plate.
Use and have the beneficial effects that produced by technique scheme: this utility model is risen by the temperature of transmission line of electricity joint and melts meltable dielectric rod, make warning sign glide in metal case to stretch out, patrol officer can more early find excess temperature warning sign, fix a breakdown in time, it is to avoid wire occurs the most so power outage because of high temperature.This utility model simple in construction, easy to use, early warning performance sensitive, it is adaptable to various transmission lines of electricity and converting equipment disconnecting link lead-in wire, transformer yoke plate lead-in wire etc., can effectively reduce maintenance number of times, especially ensure the safe operation of ultra-high-tension power transmission line.
