Abstract
The utility model provides a high-voltage switch contact resistance live-line testing device, which is characterized by comprising an insulating rod, a probe and an electricity measuring unit. The insulating rod is Y-shaped and is composed of a vertical rod and two upper supporting rods. The lower end portions of the two upper supporting rods are connected together. The upper end portion of the vertical rod is fixed to the connection part of the two upper supporting rods, while the vertical rod is positioned in the extension line of the center line of an included angle formed by the two upper supporting rods. The upper ends of the two upper supporting rods are provided with a probe respectively. The lower part of the vertical rod is provide with the electricity measuring unit. The two probes are respectively and electrically connected with the electricity measuring unit. The two upper supporting rods are connected with the vertical rod through bolts. An adjusting rod is arranged between the two upper supporting rods. One end of the adjusting rod is fixed to the left upper supporting rod, while the other end of the adjusting rod is fixed to the right upper supporting rod. The adjusting rod is at least provided with two bolt holes. Correspondingly, the right upper supporting rod is provided with bolt holes. The high-voltage switch contact resistance live-line testing device has the advantages of simple structure, convenient use and high safety performance, which can test the antenna resistance of a high-voltage switch without the interruption of power supply.
Description
Technical field
The utility model relates to high-voltage switch gear contact resistance reference test bar.
Background technology
Employed high pressure beginning in the high voltage substation; Like isolating switch, isolation shape etc.; All will carry out the contact resistance test to these high-voltage switch gears every year, and the connection terminal of this need of work in the high-voltage switch gear both sides respectively connects two balanced bridge p-wires, measures contact resistance.The maintainer generally is first power failure when measuring the contact resistance of high-voltage switch gear at present, is employed in the isolating switch both sides then and sets up two fork ladders, and two maintainers are being with p-wire binding clip climbing appearance to carry out wiring.Time-consuming, nor safety influences normal power supply.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of high-voltage switch gear contact resistance live testing device is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of high-voltage switch gear contact resistance live testing device is characterized in that: comprise insulating bar, probe and survey electric installation, insulating bar is the Y type; Be made up of vertical rod and two upper rack posts, two upper rack posts bottoms connect, and the upper end of vertical rod is fixed on two upper rack posts junctions; And vertical rod is on the center line extended line of the angle that two upper rack posts constitute; Upper end at two upper rack posts is provided with probe, is provided with the survey electric installation in the bottom of vertical rod, and two probes are electrically connected with the survey electric installation respectively.
Above-mentioned high-voltage switch gear contact resistance live testing device; Said two upper rack posts are connected through bolt with vertical rod; Between two upper rack posts, be provided with adjuster bar, an end of adjuster bar is fixed on the upper left pole, and the other end is through being bolted on the upper right pole; At least be provided with two bolts hole on the adjuster bar, also be provided with bolt hole on the corresponding upper right pole.
Adopt technique scheme; The utility model has following advantage: during use two probes are touched the high-voltage switch gear two ends; Survey electric installation and can measure the voltage at high-voltage switch gear two ends; Calculate the contact resistance at high-voltage switch gear two ends through voltmeter, thereby reach the purpose that does not have a power failure the high-voltage switch gear contact resistance is tested.Between two upper rack posts, be provided with adjuster bar, bolt is regulated the distance between two poles through different bolt hole secured adjusted bars and right pole, thereby adapts to different high-voltage switch gears.The utility model is simple in structure, and is easy to use, and security performance is high, can under the power-off condition high-voltage switch gear feeler resistance not tested.
