Abstract

The utility model relates to electric tools, in particular to a 10kV handcart switch circuit resistance test wiring assistance device which is characterized by comprising a test top plate, a test contact column and an operation rod connection port, wherein the test contact column and the operation rod connection port are respectively arranged on the upper plane and the lower plane of the test top plate. Two through holes, namely a voltage wiring hole and a current wiring hole, are respectively arranged on the inner side of the periphery of the test top plate. The length of the diameter of the test contact column is matched with the distance between two moving contacts of a handcart switch circuit, and the operation rod connection port is connected with an insulation operation rod. The 10kV handcart switch circuit resistance test wiring assistance device has the advantages of effectively avoiding heating and burning out of a fastening coil of the moving contacts of a 10kV handcart switch, leading influence of a contact resistor on resistance test of the 10kV handcart switch circuit to be greatly reduced, and greatly improving data accuracy 10kV handcart switch circuit resistance test.

Description

10kV wheelbarrow switch loop resistance test auxiliary connection device
Technical field
The present invention relates to electric power tool, specifically relate to a kind of 10kV wheelbarrow switch loop resistance test auxiliary connection device.
Background technology
The test of 10kV wheelbarrow switch loop resistance is one of Introduction on Transforming Maintenance routine work content, because 10kV wheelbarrow switch moving contact adopts two fastening coils to fix, article two, distance is narrower between the fastening coil, distance is more approaching between the voltage of circuit resistance tester, electric current clamp sectional area and the two fastening coils, electric current wiring embedding occurs during field wiring easily touch fastening coil, and large electric current is adopted in the loop resistance test, therefore cause easily the fastening line heating to blow in the test process, bring huge potential safety hazard to service work.
In addition, the long-time running of 10kV wheelbarrow switch moving contact, oxidation occurs easily, usually moving contact outside surface steel disc oxide layer is thicker, the voltage/current connection pincers all are to be clipped on the outside surface steel disc of this moving contact, the formed contact resistance of oxide layer often causes the loop resistance test result bigger than normal, brings misleading to the potential faults investigation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and effectively avoids heating to blow accident, reduces the loop-around test impact, improves the 10kV wheelbarrow switch loop resistance test auxiliary connection device of data testing accuracy.
The objective of the invention is to realize by following approach:
10kV wheelbarrow switch loop resistance test auxiliary connection device, its structural feature is: this termination includes test top board, test contact stud and hook stick connector, test contact stud and hook stick connector are installed on respectively on upper and lower two planes of test top board, be provided with two through holes along the inboard in this test top board week, this two through hole is respectively voltage wiring hole and electric current wiring hole; Distance between the diameter length of test contact stud and two moving contacts in wheelbarrow switch loop is suitable, and the hook stick connector is connected with insulated operating rod.
During use, voltage jointing clamp with circuit resistance tester is clipped on the voltage wiring hole first, the electric current jointing clamp is clipped on the electric current wiring hole, the hook stick connector connects insulated operating rod, the hand-held insulated operating rod that connects the auxiliary connection device of operating personnel, the test contact stud of auxiliary connection device is inserted in the two moving contacts inboard in 10kV wheelbarrow switch loop, and directly is electrically connected with the moving contact inner face, then test according to normal procedure.
Because voltage jointing clamp and electric current jointing clamp can be connected on the auxiliary connection device in advance, fix distance between the two, two moving contacts that directly access again 10kV wheelbarrow switch loop are inboard, effectively avoid the fastening coil heating of the 10kV wheelbarrow switch moving contact accident of blowing to occur.In addition; although the outer surface of moving contact often has layer of oxide layer; but the inner face at moving contact maintains the silver coating conductive contact; therefore adopt inserting mode can effectively reduce contact resistance; contact resistance is greatly reduced the impact of 10kV wheelbarrow switch loop resistance test, greatly improved the accuracy of 10kV wheelbarrow switch loop resistance test data.
The utility model can further be specially:
The hook stick connector is one to have the interface of female thread structure, and it is connected with the insulated operating rod spiral.
Or:
The hook stick connector is a kind of interface with external thread structure, and the end of insulated operating rod is female thread structure, and the two spiral connects.
The hook stick connector can also be the forms such as buckle connection with being connected of insulated operating rod.
In sum, characteristics of the present utility model and technological achievement are, effectively avoid the fastening coil heating of the 10kV wheelbarrow switch moving contact accident of blowing to occur, contact resistance is greatly reduced the impact of 10kV wheelbarrow switch loop resistance test, greatly improved the accuracy of 10kV wheelbarrow switch loop resistance test data.
Description of drawings
Fig. 1 is the structural representation of 10kV wheelbarrow switch loop resistance test auxiliary connection device described in the utility model.
Embodiment
Most preferred embodiment:
A kind of 10kV wheelbarrow switch loop resistance test auxiliary connection device, this termination includes test top board 2, test contact stud 4 and hook stick connector 5, test contact stud 4 and hook stick connector 5 are installed on respectively on upper and lower two planes of test top board 2, be provided with two through holes along the inboard in these 2 weeks of test top board, this two through hole is respectively voltage wiring hole 1 and electric current wiring hole 2; Distance between the diameter length of test contact stud 4 and two moving contacts in wheelbarrow switch loop is suitable, and hook stick connector 5 is connected with insulated operating rod 6.
In the 10kV wheelbarrow switch loop resistance test process, circuit resistance tester voltage wiring embedding is clipped on the voltage wiring hole 1, circuit resistance tester electric current wiring embedding is clipped on the electric current wiring hole 2, testing crew is held insulated operating rod 6, will test contact stud 4 reeve 10kV wheelbarrow switch moving contact inboards and finish test connection work.
The utility model effectively avoids the fastening coil heating of the 10kV wheelbarrow switch moving contact accident of blowing to occur, contact resistance is greatly reduced the impact of 10kV wheelbarrow switch loop resistance test, greatly improved the accuracy of 10kV wheelbarrow switch loop resistance test data.
It is same as the prior art that present embodiment is not stated part.
