Description
Technical field
The utility model is related to a kind of experimental test apparatus, and specifically one kind is applied to handcart type vacuum circuit breaker loop electricity
Hinder the joint of test.
Background technology
Carrying out when handcart type vacuum circuit breaker loop resistance is tested generally using crocodile wire clamp and loop direct current at present
Resistance tester is connected and is tested, and problems with is primarily present using crocodile wire clamp：1st, easily cause on breaker Mume flower contact
There is camber of spring in spring, such as continue to put into operation, and is easily generated heat due to contact slap and power equipment accident even occurs；2nd, crocodile wire clamp
Belong to a contact, contact surface is small, causes test data bigger than normal, and need to repeatedly be adjusted during experiment can just measure acceptance value, increase
Plus the workload of operation；3rd, crocodile wire clamp tooth is sharp, easily scratches Mume flower contact, the contact surface of Mume flower contact when reducing work
Product.The problem that these experiments are present threatens the safe operation of equipment, is badly in need of solving.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of handcart type vacuum circuit breaker loop resistance test and connects
Head, the joint can form the contact surface that good contact, contact area are big, will not scratch Mume flower contact, Er Qieneng with Mume flower contact
It is enough thoroughly to solve the problems, such as that tradition is tested using crocodile wire clamp.
The utility model solves above-mentioned technical problem with following technical scheme：
The utility model handcart type vacuum circuit breaker loop resistance test splice, the joint is stepped round copper rod structure,
Its one end is provided with the screw being connected with handcart type vacuum circuit breaker contact, and the other end is provided with and loop instrument for measuring DC resistance
The screw that testing current line the end of a thread and voltage tester line the end of a thread are connected.
The screw being connected with handcart type vacuum circuit breaker contact described in the utility model and with loop D.C. resistance survey
The screw that testing current line the end of a thread of examination instrument is connected with voltage tester line the end of a thread is respectively arranged with multiple rule, to adapt to difference
The handcart type vacuum circuit breaker of specification carries out loop resistance test and tests.
The utility model handcart type vacuum circuit breaker loop resistance test splice has the following advantages that：
1. the utility model joint is directly processed by copper rod, and conducting electric current ability is strong, and contact area is big, greatly reduces
The contact resistance of connector lug；
2. the screw hole dimensions of the utility model joint simulate the size of static contact when handcart type vacuum circuit breaker works completely,
More can truly and accurately measure the loop resistance of breaker；
3. the utility model joint joint is not contacted with Mume flower contact spring, does not result in spring scaling loss, and its contact surface is put down
It is sliding, will not also damage Mume flower contact；
4. the screw of the utility model joint can set plurality of specifications, such as can set four kinds of sizes (Φ 49mm, Φ
55mm, 79mm, Φ 109mm), the loop resistance experimental test of power network 10kV handcart type vacuum circuit breakers can be met.

The screw 3 of connection, screw 3 can be located at outer side edges, may be alternatively provided as all-pass hole, to facilitate two ends to access.
As shown in figure 3, when using, with screw by testing current the end of a thread and voltage tester line of loop instrument for measuring DC resistance
Head is separately mounted on two screws of test splice 3 and screw 2, then two test splices are separately inserted into a certain phase of breaker
Two Mume flower contacts (moving contact) on, just can carry out loop resistance experimental test.
The screw being connected with handcart type vacuum circuit breaker contact described in the utility model and with loop D.C. resistance survey
Try instrument the screw that is connected with voltage tester line the end of a thread of testing current line the end of a thread can and meanwhile set four kinds of sizes (Φ 49mm,
Φ 55mm, 79mm, Φ 109mm), with power network completely the same (the 1250A/ Φ of 10kV handcart type vacuum circuit breaker stationary contact area of beds
49mm, 1600A/ Φ 55mm, 2000A/ Φ 79mm, 3150A/ Φ 109mm, 4000A/ Φ 109mm), power network use can be met
The loop resistance experimental test of 10kV handcart type vacuum circuit breakers.
