Abstract
The utility model discloses a loop resistance testing and measuring apparatus suitable to a quincunx switch, comprising a handle, an insulating handle sleeve wrapped on the handle, a pair of pliers and a hinge pin, characterized in that the hinge pin is provided with a spring and the outer side of the pair of pliers is provided with a semicircular arc projection structure. The loop resistance testing and measuring apparatus enables measured data to approach a working state, and can enable the defects in a device to be timely discovered, thereby eliminating potential safety hazard.
Description
Technical field
The utility model relates to loop resistance measurement auxiliary part, specifically a kind of loop resistance test measurement device.
Technical background
Existing loop resistance test measurement device is like wire clamp, when measuring quincunx switch; Can cause the moving contact surface damage, contact hold tightly spring through during the 100A electric current, the distortion of can generating heat; Influence the power of holding tightly of dynamic/static contact, make contact resistance increase to continue and to produce major accident.
Summary of the invention
The purpose of the utility model is to design a kind of loop resistance test measurement device that is applicable to quincunx switch.
What the utility model will solve is that existing loop resistance proving installation can cause the moving contact surface damage, and contact is held spring heating distortion tightly, can produce the problem of major accident
The utility model analog switch running status is designed to internal connecting type with measurement mechanism by external clamping, changes the way of contact into face contact and line contact by a contact.
The technical scheme of the utility model is: the utility model comprises handle, is wrapped in insulation sleeve, binding clip and bearing pin on the handle, and bearing pin is provided with spring, and the binding clip outside is provided with the semicircular arc bulge-structure.
The utlity model has contact closely, contact area is big, near the advantage of the actual operating mode of isolating switch.Use the utility model can make measurement data more near duty, in time whether discovering device exists defective, and eliminates safe hidden trouble.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left side structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
As shown in the figure, the utility model comprises handle 2, is wrapped in the insulation sleeve 3 on the handle 2, binding clip 1 and bearing pin 4, and bearing pin 4 is provided with spring 6.Binding clip 1 outside is provided with semicircular arc bulge-structure 5.
The method of testing of the utility model is: both hands with handle 2 both sides separately, this moment, binding clip 1 was drawn close to the centre.Binding clip 1 after will closing up is put into by the inside of the quincunx contact of examination isolating switch.Release handle 2, back rely on the elastic force of spring 6 that the binding clip 1 and the inwall close proximity of quincunx contact are touched.The opening entry test figure.After test was accomplished, both hands separated handle 2 again, and middle mutually once more the drawing close of binding clip 1 this moment taken out binding clip 1 from the quincunx contact of isolating switch is inboard, and test is accomplished.
The characteristics of the utility model: 1) test surface of contact: being designed to semicircular arc bulge-structure 5 more near actual operating condition, having increased the contact area of testing clamp and test specimen, is that test result more really is reliable.Can also improve test current, test period is shortened, improve the efficient of work.2) spring: the elasticity of spring makes the utility model be connected closely with the quincunx contact of isolating switch.
Claims (1)
1. a loop resistance test measurement device comprises handle, is wrapped in insulation sleeve, binding clip and bearing pin on the handle, it is characterized in that bearing pin is provided with spring, and the binding clip outside is provided with the semicircular arc bulge-structure.
