The utility model relates to a high-voltage circuit-breaker component/resultant velocity test device, which includes a probe and a support used for fix and support the probe. The probe is a bolt, the upper end of the probe is electrically connected with a tester, a contact is arranged at the lower end of the bolt, an upper nut and a lower nut are arranged on the bolt, the bolt between the two nuts is sleeved with an insulating plate, the bolt is further sleeved with a spring, one end of the spring is propped against the lower nut, the other end is propped against the insulating plate, and the support is fixedly connected with the insulating plate. The utility model solves the problem that a linear displacement sensor of a switching characteristic tester support is damaged easily in the prior art, and has the advantages of simple structure, durability, and low cost.
Description
Technical field
The utility model relates to a kind of high-voltage circuit breaker, testing device of opening-closing speed.
Background technology
All kinds of testing tools that are used for the primary cut-out testing mechanical characteristic have various ways, but its common problem is: the sensor that is used for the displacement procedural test must be connected with tested isolating switch.Connecting needs reliably, therefore all takes to use the method that the correct position screw connects.But there are some shortcomings in this structure: impulsive force is bigger in the process of test, and sensor damages easily, instability, and also cost is also high.
Summary of the invention
For the Linear displacement transducer that solves switching characteristic tester bracket in the prior art than the problem that is easier to damage, the utility model provides a kind of switching characteristic tester test of simple and durable.
Technical solution of the present utility model:
High-voltage circuit breaker, testing device of opening-closing speed, comprise probe and the support that is used for fixing supporting probe, its special character is: described probe is a screw, and described screw upper end is electrically connected with tester, and this screw lower end is provided with the contact, described screw is provided with top nut and lower nut, be with insulcrete on the screw between two nuts, also be with spring on the described screw, this spring one end peaks on the lower nut, the other end peaks on the insulcrete, and described support is fixedlyed connected with insulcrete.
Above-mentioned screw is a brass screw.
Above-mentioned insulcrete and support are fixed by trip bolt.
The advantage that the utility model is compared with prior art had:
The utility model is to replace existing displacement transducer with a screw, and is simple in structure.And adopt screw to substitute displacement transducer, long service life, saving cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an example structure synoptic diagram of the present utility model;
Wherein: 1-support, 2-screw, 3-top nut, 4-lower nut, 5-spring, 6-insulcrete, 7-trip bolt, 8-tester, 9-mounting hole, 10-static contact, 11-moving contact, 12-contact.
Embodiment
Structural representation of the present utility model as shown in Figure 1, the isolating switch branch, testing device of opening-closing speed, comprise probe brass screw 2 and support 1, screw 2 upper ends be electrically connected with tester 8 by signal wire, the screw lower end is provided with contact 12 and moving contact 11 effects, this screw is provided with top nut 3 and lower nut 4, be with insulcrete 6 on the screw between two nuts, also be with spring 5, spring 5 one ends peak on the lower nut 4, the other end peaks on the insulcrete 6, and support 1 is fixed on the isolating switch correct position by mounting hole 9, and it is fixedlyed connected by trip bolt 7 with insulcrete 6.
Be illustrated in figure 2 as example structure synoptic diagram of the present utility model, the switching characteristic tester comprises isolating switch branch, testing device of opening-closing speed, the dynamic and static contact 10,11 of tested isolating switch and tester 8, proving installation one end electrically connects by the signal lamp D of signal wire and tester, the proving installation other end contacts to be connected with moving contact 11 again and arrives tester common port E by signal wire, forms a closed-loop path.The A of isolating switch static contact 10, B, C three-phase are linked on tester A, B, the C signal lamp by signal wire respectively.
The course of work of the present utility model:
Original state: screw 2 is transferred to contact condition with moving contact 11, and this moment, the D lamp was bright.
Making process: switch on of moving contact (whereabouts), break away from screw, this moment, the D lamp went out; When moving contact contacted with static contact, A, B, C signal lamp were bright, and tester 8 records go out to A, B, the bright time T 1 of C lamp from the D lamp, and the interval S 1 of actual measurement dynamic/static contact calculates closing speed V1.
The separating brake process: moving contact 11 and static contact 10 disjunctions, A, B, C lamp go out; Moving contact 11 contacts with screw 2, and the D lamp is bright.Tester record goes out to time T 2 of the bright record of D lamp from A, B, C lamp, survey then between the dynamic and static contact apart from S2, (this distance=open distance-over travel) calculates opening velocity V2.
