Abstract

The utility model discloses a lead connection tool for power equipment high-voltage test, which comprises an insulating rod assembled on a base, wherein the top end of the insulating rod is provided with a cruciate bracket; one end of the bracket is bent upwards, and the other end thereof is provided with a screw nut. When in power equipment high-voltage test with high-voltage class of large volume, a high-voltage lead can easily fixed on a hanger formed by bending, and the phenomenon of lead shedding can not occur during the pressurization process, the alternating current withstand value of the single insulating rod can reach 200kV, the pitch number of the insulating rod can be increased and connected in series for use, thus improving the required test voltage. The high-voltage lead can be connected conveniently and rapidly by a butterfly screw nut, thus having good electrical contact performance. The lead connection tool for power equipment high-voltage test can relieve the workload of works at height, transfer the wiring work at the upper part of the power equipment to the ground surface, reduce the frequency of changing wires at the upper part, thus further improving work efficiency, reducing construction risk, ensuring personnel safety, having small volume, light weight and simple disassembly and assembly, and being widely applied to alternating current/direct current high-voltage test of various power equipment.

Description

A kind of power equipment high-voltage test lead-in wire fastening means
Technical field
The utility model relates to power equipment high-potting dedicated pin fastening means.
Background technology
Increase day by day along with China's net capacity, electric system power transmission and transforming equipment electric pressure improves constantly, the trial voltage of power equipment also increases, this has proposed new requirement just for high-potting wiring work, at present high-voltage connection directly is connected with test apparatus or with ambroin band colligation connection, poor stability not only, and going between comes off easily, when there was wind the working site, lead-in wire the personnel that easily cause that swing got an electric shock.Because lead-in wire line footpath is thinner, easily cause loose contact when being connected in addition, the accuracy that influence is measured with test apparatus.Because when the high-potting work of carrying out power equipment, the high-voltage connection that test apparatus is connected with power equipment must with ground and on every side other object keep certain air line distance, how will go between fixation and contact well, keep enough safe distances over the ground again, become a urgent problem.
Summary of the invention
For solving the connection and the fixation problem of transformer station's site test working voltage lead-in wire, the utility model provides a kind of power equipment high-voltage test lead-in wire fastening means, to overcome the prior art drawback.
The utility model purpose realizes in the following manner: this high-voltage test lead-in wire fastening means comprises the insulating bar that is installed on the base, insulating bar top installing one "+" shape support, and described support one end is bent upwards, and the other end is equipped with nut.
Described insulating bar is at least single or mutual serial connection many.
The technical progress that the utility model is obtained: owing to adopt power equipment high-voltage test lead-in wire fastening means of the present utility model, make electric system high-potting personnel when high pressure experiment works such as the power equipment that carries out the high capacity voltage levels such as transformer, mutual inductor, power cable, GIS, can easily high-voltage connection be fixedly secured on the hook that the utility model is bent to form, the phenomenon that goes between and come off can not appear in pressure process, and maintain enough distances over the ground, more be applicable to high-potting work.By Test Summary, the utility model also has following characteristics:
1, insulating property are good.The ac voltage withstanding value of single insulating bar can reach 200kV, and the joint number of insulating bar can increase serial connection and use, thereby improves required trial voltage.
2, easy to connect.High-voltage connection can conveniently connect by the special butterfly nut of insulating bar top "+" shape support one end assembling, and has well electrically contacting property.
3, good stability.Because insulating bar is installed on the heavier metab, base has good stability with after insulating bar is connected horizontal positioned.
The utility model also can alleviate the workload of high-rise working when working as the wiring of high-power transformer top, can transfer to ground to the wiring work on power equipment top as far as possible, reduce the number of times of top change wiring, and then increase work efficiency, reduce construction risk, guarantee workmen's personal safety.And volume is little, in light weight, dismounting is simple, is easy to carry, and can be widely used in the alternating current-direct current high-voltage test of all kinds of power equipments.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model one-piece construction synoptic diagram.
Embodiment
As shown in Figure 1, this high-voltage test lead-in wire fastening means comprises the epoxy resins insulation bar 2 that is installed on the stainless steel base 1, insulating bar 2 tops installing one "+" shape support 3, support 3 one ends are bent upwards, and crooked formed hook 5 is in order to hang high-voltage connection; Support 3 other end spinning butterfly nuts 4.Insulating bar 2 is single in the present embodiment, and according to required trial voltage situation, the joint number of insulating bar 2 can be many of mutual serial connection.
After being tightened on insulating bar 2 on the base 1, the joint of high-voltage connection (shielding line) end is affixed to butterfly nut 4 places of insulating bar 2, the other end causes the conductor place of tested power equipment, the dedicated pin of each test apparatus equipment will be fixed connection point with the conductor part of insulating bar 2, the thread-changing pressurization successively of different tests project, directly the trial voltage electric current is transported on the power equipment by high-voltage connection (shielding line), can bears the ac voltage withstanding of 200kV through test.Be higher than this value as the trial voltage of being done, can be connected in series more piece insulating bar 2.High-tension shielding wire core and test apparatus industrial siding are connected on the top of insulating bar 2 simultaneously, and tighten with butterfly nut 4, and good to guarantee contact, unnecessary high-voltage connection (shielding line) is suspended on hook 5 places, with slip-off preventing.

Claims (2)

1. a power equipment high-voltage test lead-in wire fastening means is characterized in that it comprises the insulating bar that is installed on the base, insulating bar top installing one The shape support, described support one end is bent upwards, and the other end is equipped with nut.
2. power equipment high-voltage test lead-in wire fastening means according to claim 1 is characterized in that described insulating bar is single or mutual serial connection many.
