Description

A kind of lead-in wire junction box for overhead conductor insulation test
Technical field
The utility model relates to a kind of lead-in wire junction box for overhead conductor insulation test.
Background technology
Hi-line refers to the transmission line of electricity carrying 10KV (containing 10KV) above voltage, and along with the construction of electrical network, hi-line has become the important component part on power transmission network.High voltage power transmission generally adopts the cable underground of tape insulation layer to transmit in city, often adopt shaft tower carrier hollow wire mode to transmit in the wild.Therefore aerial condutor is all with high-tension, and the aerial condutor daily servicing of high pressure just seems extremely important, if aerial condutor occurs that leaky gently, causes fire, heavy then threaten personal safety.
And exactly Insulation test is carried out to it as one of aerial condutor important daily servicing, the overhead conductor insulation test of prior art uses insulation measurement instrument to be connected with aerial condutor, and due to insulation measurement instrument manufacture reason, the length of wiring in insulation measurement instrument is generally connected with aerial condutor all not, and usual way is exactly by aerial condutor and insulation measurement Instrument connection with lead-in wire.But insulation measurement instrument and aerial condutor are all high pressure, so lead-in wire is in use also with high voltage.
In the overhead conductor insulation test of prior art; lead-in wire generally all drags on the ground; due to lead-in wire with high voltage routine use can only be below shaft tower for the area of concrete floor or more dry bath, weather be eyeball bright; if encounter grow wild mountain area weeds, the environment in ponding location or other dislike strong environment when Insulation test operation is carried out to aerial condutor; because the insulation protection degree of lead-in wire is not high, be easy to produce conduction and staff dare not use.If employing, at lead-in wire below place mat insulating material, can cause operating cost to increase, therefore in the overhead conductor insulation method of testing of prior art, lead-in wire uses not safely and uses and is subject to operating environment restriction; Go between in use, when not by instrument, the process of carrying out unwrapping wire and take-up is oversize, loses time simultaneously.
Utility model content
Technical problem to be solved in the utility model, that be just to provide a kind of insulation safety, the simple to operate lead-in wire junction box for overhead conductor insulation test, can realize safety and quickly retracting line.
Solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of lead-in wire junction box for overhead conductor insulation test, comprise lead-in wire, it is characterized in that also comprising: an insulated wire case, its casing has in a bracing wire hole, casing and be provided with a dielectric level spool, the online case two side of two supports of horizontal roll bobbin passes sidewall, one end of horizontal roll bobbin is fixed with insulation turning handle, the other end has axial hole, is communicated with a radial hole at the bottom of axial hole; It is outside exposed that one end of described lead-in wire passes described bracing wire hole with insulation measurement Instrument connection, the other end after the radial hole, axial hole of spool after being wrapped in spool.
Described line case stack shell outer wall is also provided with an Insulated winding wire plate, and described wire-wrap board by the ground wire that needs to use in Insulation test process together around on line case, can be convenient for carrying.
One end of described lead-in wire with the mode of insulation measurement Instrument connection is after the radial hole, axial hole of spool: the Connection Block being provided with insulation in axial hole, connecting line the end of a thread of insulation measurement instrument is set to plug.
Described line case can be cylinder or square body.
Bottom described line case stack shell, a base for supporting is also housed, described base for supporting is made of metal, and during use, the direct ground connection of base for supporting can be the function that whole device provides ground connection ground wire.
During use, insulation measurement instrument is connected with lead-in wire by the Connection Block of spool in insulated wire case, simultaneously the exposed other end adjustment that goes between can be pulled to go between the length of wiring according to the distance of Insulation test instrument and aerial condutor, and be connected with aerial condutor, this just can make whole lead-in wire be in vacant state can not ground connection, prevent being with the lead-in wire of high tension voltage to be connected to ground and produce conduction thus the personal safety of effective guarantee user of service, even grow wild mountain area weeds like this, the environment in ponding location or other dislike strong environment and also can carry out overhead conductor insulation test.Simultaneously in retractable cable process, turning handle can realize quickly retracting line.
Compared with prior art, the utility model instrument has the following advantages:
The utility model adopts insulated wire case lead-in wire to be put the state that can realize lead-in wire in the inner and keep insulated aerial in Insulation test process, thus reach the effect of insulation safety, the personal safety of effective guarantee user of service, simultaneously in retractable cable process, can can realize quickly retracting line by turning handle, simple to operation.
