Abstract
It is suitable for test the utility model discloses one kind and is shorted ground line with quick, including eight conducting wires and ground terminal, eight conducting wire one end are respectively connected with conductor grip, the other end is parallel-connected to ground line, the ground line other end is connected to ground terminal, and eight conducting wires and ground line surface are respectively provided with transparent sheath.The utility model can reduce tester and wind the short circuit time when testing at the scene, ground terminal need to be only grounded by test process operating personnel, conductor grip is clipped on non-tested device, the time of test is greatly shortened, while can also prevent to leave security risk of the shorting stub in equipment.
Description
Technical field
The utility model belongs to ground line technical field, and in particular to one kind is suitable for test and is shorted ground line with quick.
Background technique
It in the power system, can timely discovering device internal electric or machinery side by carrying out high-potting to equipment
The defect in face, and eliminated by carrying out maintenance to the defect equipment checked, serious person is replaced, in order to avoid transported in equipment
It breaks down in row, therefore carrying out high-potting to equipment is to guarantee the important measures of equipment safety operation.
When carrying out high-potting to equipment, it usually needs be shorted to non-tested device, therefore we will face
Following problem: test shorting stub is in disorder: in daily performulation, carrying out acting characteristic test, insulation resistance, pressure resistance to breaker
When test, generally requiring to be shorted breaker, existing shorting stub is hand-made bare conductor, it is different in size, it generally requires
More shorting stubs are overlapped, and can be existed after the completion of test and be forgotten the case where receiving shorting stub generation, bare conductor may also can leave line
Must be on contact of breaker, there are the security risks of especially severe；Frequently equipment is wound, high pressure is being carried out to equipment
When test, tester needs repeatedly to be shorted in test, such as is carrying out casing Dielectric Loss Test to high voltage side of transformer
When, staff first has to medium voltage side, low-pressure side being shorted ground connection, and after completing high-pressure side test job, side test is pressed in centering
When, high-pressure side and low-pressure side are carried out short circuit ground connection again by staff, so that tester needs frequently to remove short circuit
Line is frequently wound equipment, so not only inefficiency, and time-consuming, it is also possible to the peace removed is forgotten there are shorting stub
Full hidden danger, therefore, the winding time for reducing operation is our problem encountered.
Summary of the invention
The technical issues of the utility model solves is: providing one kind and is suitable for test quickly short circuit ground line, to solve
Above-mentioned problems of the prior art.
The technical solution that the utility model is taken are as follows: one kind is suitable for test and is shorted ground line with quick, including eight are led
Line and ground terminal, eight conducting wire one end are respectively connected with conductor grip, and the other end is parallel-connected to ground line, are grounded the other end
It is connected to ground terminal, eight conducting wires and ground line surface are respectively provided with transparent sheath.
Eight conducting wires and ground line are all made of 25mm2Multiply soft copper conducting wire.
The utility model has the beneficial effects that compared with prior art, survey can be reduced when the utility model is tested at the scene
Examination personnel, which wind, is shorted the time, and ground terminal need to only be grounded, conductor grip is clipped on non-tested device by test process operating personnel
, the time of test is greatly shortened, while can also prevent to leave security risk of the shorting stub in equipment, transparent sheath plays
Perspective protection insulating effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing and the utility model is described further in specific embodiment.
Embodiment 1: as shown in Figure 1, a kind of be grounded suitable for test with quick be shorted, including eight conducting wires 1 and ground connection
Terminal 2, eight 1 one end of conducting wire are respectively connected with conductor grip 3, and the other end is parallel-connected to ground line 4, and 4 other ends of ground line connect
It is connected to ground terminal 2, eight conducting wires 1 and 4 surfaces of ground line are respectively provided with transparent sheath.
Preferably, above-mentioned eight conducting wires 1 and ground line 4 are all made of 25mm2 multiply soft copper conducting wire.
When carrying out the test such as high voltage side of transformer casing Dielectric Loss Test, insulation resistance, ground terminal is grounded by operating personnel,
7 in 8 hand held conductor grips are clipped in transformer medium voltage side and low-pressure side respectively, when carrying out medium voltage side, low-pressure side test
Similarly, non-tested device can be realized and be quickly shorted ground connection.
As seen from the figure, test is easy to operate with ground line is quickly shorted, and non-quilt can be realized by simple clip
Examination equipment is quickly shorted ground connection.It reduces staff and arranges shorting stub and climbing-up equipment number.
The utility model has the advantages that
1) safety benefit: analyzing from test situation at this stage, and field operation bring ergonomic is low, operating risk is high,
The influence that time-consuming is avoided that traditional short circuit method time is long, frequently winds shorting stub using test with ground line is quickly shorted
And shorting stub bring security risk is left, reduce test jobs risk；
2) economic benefit: carrying out preventive trial instead of existing shorting stub with quick short circuit ground line using test, will be big
It is big to shorten the equipment prerun time, equipment power off time is reduced, equipment year utilization rate is improved, means to set for power grid enterprises
It is standby can export to the greatest extent can be more electricity, obtain more economic benefits.
3) improve electric network reliability: for only having for double loop power supply in substation, inlet wire power failure prerun can increase all the way
The risk of operation of power networks reduces the activity duration, shortens the power off time of equipment, make to stop using test with ground line is quickly shorted
Electric equipment improves the reliability of operation of power networks than application power off time putting into operation earlier.
Example above description is only a specific implementation of the present invention, the protection scope of the utility model not office
It is limited to this.Be familiar with the those skilled in the art within the technical scope disclosed by the utility model, can easily find variation or
Alternative, these should be covered within the scope of the utility model.For this purpose, the protection scope of the utility model should be with
Subject to the scope of protection of the claims.
