Abstract
Provided is a special-purpose potential sampling clamp, which comprises handles, a connection shaft and binding clips. Each handle is hinged to one binding clip via the connection shaft, the binding clip is of a slotted structure, a flat jaw is arranged in face-to-face surfaces of the two binding clips, the end portion of each handle is provided with a connector lug which is movably connected with a potential sampling wire of a loop resistance tester, and the handles and the binding clips are conductive and are covered by insulating layers. The special-purpose potential sampling clamp is simple in structure, convenient in user, stable and reliable in contact connection, low in investment and wide in application prospect; completely avoids disadvantages of traditional clamps including being easy to loosen or fall off; and can be widely applied to loop resistance testers of switched in KYN-series switch cabinets.
Description
Technical field
The utility model relates to a kind of current potential sampling instrument, particularly a kind of current potential sampling clamp specially.
Background technology
Along with the needs of electric system fast and stable development in recent years, the demand of 10kV KYN type switch cubicle greatly increases, and the use amount of vacuum switch also rises year by year in the corresponding cabinet.Vacuum switch carries out in the process of loop resistance test in to such cabinet, the staff finds because the design feature of the interior vacuum switch self of cabinet, add the defective that conventional pliers exists, there is the problem that test method is loaded down with trivial details, test the sampling spot virtual connection, cause the test figure domain of walker big, test number (TN) increases, and has increased checking experiment personnel's workload.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provide a kind of and be easy to carry, easy to assembly, use simple and meet the current potential sampling clamp specially applicable to vacuum switch loop resistance test in the switch cubicle of work on the spot requirement and safety condition.
A kind of current potential sampling clamp specially, include handle, coupling shaft and binding clip, handle and binding clip are hinged by coupling shaft, its structural feature is: described binding clip is the in-line structure, the forward surface of two binding clips is provided with the jaw of platypelloid type, be provided with the connector lug that can flexibly connect with the current potential sample line of circuit resistance tester in the end of handle, handle and binding clip have electric conductivity, are coated with insulation course in the outside of handle and binding clip.
The current potential sampling clamp specially of this structure, in use, 2 current potential sample line of circuit resistance tester are inserted respectively on the connector lug of 2 cover current potential sampling clamp specially pincers handle tails, vise two groups of moving contacts of vacuum switch in the 10kV KYN type switch cubicle again with 2 jaws respectively, can realize the function to vacuum switch current potential sampling in the switch cubicle.
The jaw of the platypelloid type that arranges on the described two binding clip forward surfaces is the jaw that two binding clips are square when closing up.
The jaw that is square when adopting this closing up, the top of jaw is enclosed when closing up, and can improve contacting of vacuum switch moving contact in this current potential sampling clamp specially and the switch cubicle like this, improves the accuracy of sampling.
Jaw is provided with contact chip, is provided with the friction line on the surface of contact chip.
By at jaw contact chip being set, and at contact chip the friction line is set, can improves the clamping degree of this current potential sampling clamp specially so on the one hand, the opposing party also can improve the serviceable life of current potential sampling clamp specially.
Described connector lug is the connector of plug-in type.
Connector lug is provided with insulator cap and fixes.
Described binding clip length is 24～25mm, and wide is 3～5mm.
In sum, the utility model following advantage compared to existing technology:
Current potential of the present utility model sampling clamp specially is simple in structure, easy to use, it is stable, reliable that the contact connects, and has avoided the conventional pliers shortcoming of loosening, landing easily fully; Input cost is low, and application prospect is extensive, can be applicable on the circuit resistance tester of switch in the KYN series switch cabinet.

Embodiment
Be described in more detail below in conjunction with the utility model of embodiment.
Embodiment 1
A kind of current potential sampling clamp specially as shown in Figure 1, include handle 3, coupling shaft and binding clip 6, handle and binding clip are hinged by coupling shaft, described binding clip is the in-line structure, the forward surface of two binding clips is provided with the jaw 2 of platypelloid type, be provided with the connector lug 4 that can flexibly connect with the current potential sample line of circuit resistance tester in the end of handle, handle and binding clip have electric conductivity, are coated with insulation course in the outside of handle and binding clip.Described handle and pincers are made for adopting copper material, and described insulation course is for adopting light-duty insulating material, and the jaw of the platypelloid type that arranges on the described two binding clip forward surfaces is the jaw that two binding clips are square when closing up.Jaw is provided with contact chip 1, is provided with the friction line on the surface of contact chip.Described connector lug is the connector of plug-in type.Connector lug is provided with insulator cap and fixes.The current potential sample line movable connection method of circuit resistance tester peg graft with connector lug on, and fix with insulator cap.Described binding clip is long to be 24.5mm, and wide is 4mm.
As shown in Figure 2,2 current potential sample line of circuit resistance tester are inserted respectively on the connector lug of 2 cover current potential sampling clamp specially handle end, and tighten insulator cap, vise two groups of moving contacts 5 of vacuum switch in the 10kV KYN type switch cubicle again with 2 jaws respectively, can realize the function to vacuum switch current potential sampling in the switch cubicle.
It is same as the prior art that present embodiment is not stated part.
