Abstract
The utility model relates to a grounding device for power equipment in a power system and particularly discloses a grounding wire for a transformer test. The grounding wire for the transformer test comprises clamping pieces, springs, soft copper wires and a junction box, and is characterized in that: one end of the junction box is connected with one soft copper wire and the other end of the junction box is connected with three soft copper wires; and the tail end of each soft copper wire is connected with a clip. By the technical scheme, the utility model has the advantages that: the grounding wire is convenient to install and reliable in connection, can be portably carried, ensures the safety, and improves the work efficiency of maintainers and testers of transformer substations.
Description
Technical field
The utility model relates to the earthing device of using on the power equipment in a kind of electric power system, especially discloses a kind of transformer test and has used earth connection.
Background technology
According to the requirement of " electric power safety working regulation " and " power equipment preventive trial rules ", need regularly carry out preventive trial to transformer.When defective or fault appear in electric power system, need overhaul transformer, make an experiment then, can put into operation after the pass the test.
As requested, transformer is carried out routine property tests such as absorption ratio test, D.C. resistance test, dielectric loss test, AC voltage withstand test, DC voltage withstand test, oil sample test.Often need be to the transformer low voltage short circuit, the high pressure energising.According to the rules requirement, should be on transformer the earth connection of installation qualification, the test that can be correlated with or service work.Present substation equipment maintenance and repair personnel are wrapped in fine copper wire respectively on the contact of step down side three-phase sleeve pipe, then ground connection when making an experiment.This operation is inefficiency both, and is inconvenient again, connects also insecurely, and do not meet the rules requirement.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of easy for installation that the utility model provides, and connects reliably, carries lightly, guarantees that the transformer test of safety is used earth connection.
The utility model solves the problems of the technologies described above the technical scheme that adopted like following description:
A kind of transformer test is used earth connection, comprises intermediate plate, spring, annealed copper wire, junction box; Junction box one end connects 1 annealed copper wire, and the terminal clip that connects is on ground network, earth stud, ground connection band iron etc.; The other end connects 3 annealed copper wires, and terminal 3 clip that connect are on the contact of step down side three-phase sleeve pipe.
Described intermediate plate is made by electric conducting material.
Described annealed copper wire is outer by soft RVV protection.
Described clip is made up of intermediate plate and spring.
The utility model the beneficial effect of having taked technique scheme such as below description:
Easy for installation, connect reliably, carry lightly, guarantee safety, improved the maintenance personal's of transformer station operating efficiency.
Description of drawings
Through the description of its exemplary embodiment being carried out below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the present invention will become apparent and understand easily.
Fig. 1 is the structural representation of a kind of transformer test of the utility model with earth connection.
Fig. 2 is the profile of the annealed copper wire of the utility model.
Among the figure, 1 intermediate plate, 2 springs, 3 annealed copper wires, 4 junction boxs, 5 RVVs.
Embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description.
Fig. 1 is the structural representation of a kind of transformer test of the utility model with earth connection.
As shown in the figure, this device comprises, intermediate plate 1, spring 2, annealed copper wire 3, junction box 4, RVV 5.
Wherein with junction box 4 one ends be clipped in (wherein clip is made up of intermediate plate 1 and spring 2) on the contact of step down side three-phase sleeve pipe respectively through clip with annealed copper wire 3, the annealed copper wire 3 with junction box 4 other ends is fixed on ground network, earth stud, the ground connection band iron etc. through clip again.
It should be noted that; Above-mentioned specific embodiment is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve perhaps distortion all in the protection range of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection range of the utility model is limited claim and equivalent thereof.
