Abstract

The invention discloses a high-voltage test junction pole, which relates to the technical field of electric power circuit high-altitude test tools, and includes an insulated rod and a hook, wherein the insulated rod is a hollow rod; a first connecting sleeve provided with a closed end is arranged at the upper end of the insulated rod; a center hole is formed in the closed end of the first connecting sleeve; the hook includes a lifting hook and a straight rod; threads are arranged at the tail end of the straight rod of the hook; the tail end of the straight rod of the hook penetrates through the insulated rod through the center hole of the first connecting sleeve; a test lead penetrating from the inside of the insulated rod is fixedly connected with the hook through a nut. The test lead in the high-voltage test junction pole penetrates through the inside of the insulted rod, so that electric shock to body or equipment short-circuit accident caused by the fact that the test lead falls down and flies is effectively avoided, and potential safety hazard is reduced.

Description

The high-potting junction pole

Technical field

The present invention relates to power circuit altitude test technical field of tools.

Background technology

Electric power preventive trial and repair based on condition of component routine test are important steps in power equipment operation and the maintenance work, are one of effective means that guarantees safe operation of power system.The electric power preventive trial refers to inspection, test or monitoring that the equipment that put into operation test condition (as testing equipment, environmental baseline, test method and the trial voltage etc. of regulation), pilot project and the test period according to the rules carried out.It is that can judgment device continue to put into operation, and prevention has an accident and the important measures of device damage and packaging facilities safe operation.

In existing preventive trial and the repair based on condition of component routine test process, in most cases all be altitude hot-line operation, connecting test lead needs the staff to climb up the high-altitude, and operation is loaded down with trivial details, labour intensity is big, inefficiency, and staff's safety coefficient reduces.The traditional wired method is to adopt methods such as hoistable platform, insulating ladder.Adopt hoistable platform operating personnel labour intensity big, use the restriction that is subjected to landform, be difficult to lose time near tested device, reduce work efficiency, and there is very big danger in operating personnel's personal safety; And the insulating ladder instability, also fracture easily, the high-altitude takes place easily falls, and has great potential safety hazard.

The high-potting specific purpose tool that adopts is the high-potting bar at present, in use directly with the high-potting wire clamp or be connected on the masthead portion that articulates, and the top is difficult for fixing, gently then loose contact influences test effect, heavy then since test wire long test wire is come off or under strong wind weather, hikes up cause the person to get an electric shock or the equipment short circuit accident.

Summary of the invention

Technical matters to be solved by this invention provides a kind of high-potting junction pole simple in structure, esy to use, safe and reliable, can effectively prevent from getting an electric shock or the equipment short circuit accident because test wire comes off and hikes up the person that causes, and reduces potential safety hazard.

For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of high-potting junction pole, comprise insulating bar and hook, and described insulating bar is hollow stem, its upper end is provided with first adapter sleeve of end sealing, and the blind end of described first adapter sleeve is provided with center pit; Described hook comprises suspension hook and straight-bar, and the end of its straight-bar is provided with screw thread, and the end of described hook straight-bar penetrates in the insulating bar by the center pit of first adapter sleeve, and the test lead that passes from the inside of insulating bar is fixedlyed connected with hook by nut.

Preferably, the side of described insulating bar lower end is provided with wire hole, and test lead is drawn from wire hole.

Preferably, described insulating bar is more than two, links to each other by second adapter sleeve between it, and the outside surface of described second adapter sleeve fixedly has brace, and described brace is provided with connection terminal, and described test lead links to each other with connection terminal.

Preferably, described brace is fixedly linked by bolt and second adapter sleeve.

The beneficial effect that adopts technique scheme to produce is: test lead of the present invention passes from the inside of insulating bar, can effectively prevent long because of test wire, difficult fixing, the factor that easily hikes up of strong wind weather test wire, and the person that causes gets an electric shock or the equipment short circuit accident, effectively reduces potential safety hazard.Test lead is connected on the connection terminal, plays the center fixed effect, and it is unstable to prevent that test wire from floating.

Description of drawings

Fig. 1 is structural representation of the present invention;

Mark among the figure: 1-hook; The 2-center pit; The 3-nut; 4-first adapter sleeve; The 5-insulating bar; The 6-test lead; 7-second adapter sleeve; The 8-brace; The 9-connection terminal; The 10-bolt; The 11-wire hole.

Embodiment

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, the high-potting junction pole comprises insulating bar 5 and hook 1, and described insulating bar 5 is hollow stem, and its upper end is provided with first adapter sleeve 4 of end sealing, and the blind end of described first adapter sleeve 4 is provided with center pit 2; Described hook 1 comprises suspension hook and straight-bar, and the end of its straight-bar is provided with screw thread, and the end of described hook 1 straight-bar penetrates in the insulating bar 5 by the center pit 2 of first adapter sleeve 4, and the test lead 6 that passes from the inside of insulating bar 5 is fixedlyed connected with hook 1 by nut 3.

Preferably, the side of described insulating bar 5 lower ends is provided with wire hole 11, and test lead 6 is drawn from wire hole 11; Test lead 6 also can directly be guided on the testing equipment on ground from the inside of insulating bar 5, and visual concrete operating environment and arranging is beneficial to test lead 6 stable getting final product.

Preferably, described insulating bar 5 is more than two, link to each other by second adapter sleeve 7 between it, the outside surface of described second adapter sleeve 7 fixedly has brace 8, and described brace 8 is provided with connection terminal 9, and described test lead 6 links to each other with connection terminal 9, play center fixed connection effect, both shortened the length of required test wire, it is unstable to prevent that test wire from floating, and also can guarantee to connect safe and reliable.

Preferably, described brace 8 is fixedly linked by bolt 10 and second adapter sleeve 7, also can directly be welded on second adapter sleeve 7.

Test lead 6 passes in insulating bar 5, the upper end bolt, after drawing, the lower end is fixed on the connection terminal 9, be equivalent to shorten the length of test wire, test lead 6 is not subjected to the influence of easy extraneous weather in insulating bar 5 inside, during test the test wire of drawing from testing equipment is directly received on the connection terminal 9, hang on the tested high-tension line and get final product with hook 1, for than higher measurement circuit, can connect to reach test height by many insulating bars 5.

It is long because of test wire, difficult fixing that the present invention can effectively prevent, the factor that the strong wind weather test wire easily hikes up, and the person that causes gets an electric shock or the equipment short circuit accident, can effectively reduce potential safety hazard.
