At present, integral type electric leakage measuring instrument (see Fig. 1) that market produces, improves the speed of leak current fault investigation to a certain extent, but there is following drawback when investigating overhead transmission line leak current fault:
1, poor stability:
(1) falling from high altitude is dangerous, need step on bar or ascending stair operation when detecting operation;
(2) Danger Electric shock risk is high, and when detecting bare conductor electrical leakage, the distance of operating personnel and electrified body is near, and have certain risk, as inclement weather, danger is larger;
2. the working strength of ascend operation is large;
3. antijamming capability is weak, and when having high-intensity magnetic field to disturb around detection site, the electrical leakage data of measurement are unstable, sometimes cannot reading;
4. investigate leak current fault speed slow, ascend operation have impact on investigation speed.
Therefore, in the urgent need to improving integral type electric leakage measuring instrument, developing easy to operate, that antijamming capability is strong split type electric leakage measuring instrument, eliminating during integral type electric leakage measuring instrument uses the drawback occurred.
Summary of the invention
Goal of the invention: for the defect of existing integral type electric leakage measuring instrument, develops a kind of easy to operate, split type electric leakage measuring instrument that antijamming capability is strong.
Technical scheme: a kind of split type electric leakage measuring instrument, comprise probe 1, display 2, it is characterized in that, described probe 1 has installed additional 4 blocks of fan-shaped polyester insulated plates 11, during operation, wire to be measured is put into the angle that polyester insulated plate 11 is formed, by upwards pushing up or pull down probe 1, forcing probe to open, opening probe without the need to manually pressing; Described probe 1 is connected with shielding line 3 with between display 2, strengthens the antijamming capability of data line, simultaneously convenient operation personnel reading numerical values; The insulating telescopic bar 4 adapted with line levels is installed in the bottom of described probe 1, is convenient to testing staff and stands on ground and operate.
Preferably, change ordinary silicon steel plate iron core original in described probe 1 into performance more excellent high-density silicon steel disc, when having magnetic interference around detection site, the electrical leakage of measurement is substantially unaffected; The length of described shielding line 3 is determined according to action need, is generally about 10m; The thick 2mm of described polyester insulated plate 11, makes the fan shape of 40*30mm, pastes on probe with ab composite glue, ensures that the internal diameter of probe is greater than 35mm; Described polyester insulated plate 11 smooth surface, is convenient to large model wire and can enters smoothly and not damage wires.
The beneficial effects of the utility model: the utility model is a kind of instrument detecting low-voltage overhead line road electrical leakage, has following innovative point and advance compared with integral type leakage detector:
1. security is high.
(1) dangerous without falling from high altitude, only need stand on ground during detection and operate instrument.
(2) Danger Electric shock risk reduces, and the distance detected between operating personnel and overhead transmission line is greater than safe distance.
2. testing intensity is little, without the need to ascend operation.
3. antijamming capability is strong, and ordinary silicon steel plate iron core is changed into the high-density silicon steel disc that performance is more excellent, when having magnetic interference around detection site, the electrical leakage of measurement is substantially unaffected.
4. investigate leak current fault speed fast, due to only operation need be detected on the ground, without the ascend operation time, therefore improve troubleshooting speed.
