Description
Technical Field
The utility model relates to a generating line test device especially relates to one kind and is arranged in electric power system to the experimental termination of transformer substation's generating line, can be applied to the affiliated electrical test specialty of electric power system.
Background
At present, when a bus, especially a tubular bus, is tested in an electrical system, because the clamping opening of the existing test wire clamp is too small, the bus cannot be directly connected, and the test wire clamp needs to be clamped to the connection part of equipment such as a disconnecting link and the like and the bus. However, the above wiring has two disadvantages:
1) the test error is large, and the precision is not high. Taking a 220kV substation as an example, the bus is generally a tubular bus. When a bus loop resistance test is performed, a tester needs to clamp a test wire clamp to a bus side knife switch static contact of two lines to complete the test. The test data contains the numerical value between the static contact of the side knife switch of the bus and the bus, and the numerical value cannot be excluded, so that the measured data has errors, the accuracy is not high, and the bus state cannot be truly reflected.
2) The working efficiency is low, and the potential safety hazard is large. In the test process, when the experimental wiring of testing personnel change, need to ascend a height many times and go on, waste time and energy to there is the danger that the eminence falls, has very big potential safety hazard.
Therefore, the accuracy of the transformer substation bus test is guaranteed, the efficiency and the safety of the test work are improved, and the trouble and the inconvenience brought to testers by the transformer substation bus test are thoroughly solved.
SUMMERY OF THE UTILITY MODEL
The utility model is exactly for solving above-mentioned technical problem, provide one kind not only can conveniently carry out the transformer substation generating line test, but also can reduce test error, avoid the experimenter to ascend a height and change experimental wiring, provide the experimental termination of transformer substation generating line in the electric power system that is arranged in of guarantee for personal safety.
In order to solve the technical problem, the utility model discloses a technical scheme as follows:
the utility model provides a transformer substation's bus test termination, including pressing from both sides mouthful part and supporting control part, press from both sides mouthful part by last metal clamping piece and metal clamping piece down and set up the spring mechanism in its centre and constitute, support control part by metal clamping piece fixed row down, insulating rope, combination formula insulator spindle, insulating rope operating mechanism constitute, lower metal clamping piece is through metal clamping piece fixed row and combination formula insulator spindle fixed connection down, through setting up insulating rope operating mechanism pulling insulating rope control spring mechanism flexible in combination formula insulator spindle lower part.
The contact surfaces of the upper metal clamping piece and the lower metal clamping piece with the bus are frosted surfaces.
The length of the combined insulating rod is adjustable.
A fixing rod penetrates through the spring in the spring mechanism, so that the spring is prevented from deforming in the pulling process.
The main function of the upper metal clamping piece and the lower metal clamping piece is to form a clamping opening, a bus can be clamped into the clamping opening, and the contact surface of the bus and the bus is a frosted surface, so that full contact can be guaranteed.
The main function of the spring mechanism is to adjust the size of the clamping opening of the upper metal clamping piece and the lower metal clamping piece so as to adapt to different bus specifications. The main function of the insulating rope is to control the spring mechanism, thereby adjusting and adjusting the size of the clamping opening of the upper metal clamping piece and the lower metal clamping piece.
The main function of the lower metal clip fixing row is to fix the lower metal clip and the spring mechanism so as to fix them on the combined insulating rod.
The combined insulating rod has the main function of integrally supporting the device, is divided into four sections, and can be combined into multiple sections according to different bus heights of a transformer substation to adjust the length.
The main function of the insulating rope operating mechanism is to pull the insulating rope through a rocker so as to control the spring mechanism and fix the insulating rope at a proper position.
Compared with the prior art, the beneficial effects of the utility model reside in that: the precision of the transformer substation bus test is improved, the defects of the prior art are overcome, and the double promotion of the test accuracy and the safety is realized. Has the advantages of convenient carrying, time-saving and labor-saving operation, safety and reliability.

Detailed Description
The present invention will be described in further detail with reference to examples. The following embodiment is only a specific embodiment of the present invention, but the design concept of the present invention is not limited thereto, and all the modifications to the present invention by using the design concept are insubstantial modifications and shall be within the protection scope of the present invention.
Example 1
As shown in figure 1, a novel bus test wiring device of transformer substation, during the application, press from both sides the instrument test fastener on last metal clamping piece 1 and lower metal clamping piece fixed row 4, assemble 6 length of combination formula insulator spindle to being tried the generating line highly uniform again, through 5 control spring mechanism 3 of insulating rope 5 control of rocker pulling of insulating rope operating mechanism 7 to metal clamping piece 2 positions under the regulation, make the mouth distance of pressing from both sides accord with being tried the generating line cross-section. And the insulating rope 5 is loosened, so that the tested bus clamp can be tested after the tested bus clamp is clamped by the upper metal clamping piece 1 and the lower metal clamping piece 2, the wiring difficulty in the conventional bus test is avoided, and the test error is reduced.
Example 2
When experimental wiring of change, the insulating rope 5 control spring mechanism 3 of rocker pulling that passes through insulating rope operating mechanism 7 on ground adjusts metal clamping piece 2 down, makes the mouth of clamp distance between metal clamping piece 1 and the lower metal clamping piece 2 be greater than the bus cross-section of being examined, and rethread combination formula insulator spindle 6 takes off the device and can trade the line work on ground, has avoided ascending a height to trade the line and the potential safety hazard that causes.
The utility model has the advantages of simple and reasonable structure, the practicality is strong, and is effectual, does benefit to popularization and application.
