Description
Technical field
The utility model belongs to High-Voltage Electrical Appliances control appliance field, particularly relates to a kind of vacuum circuit-breaker that the electronic type contact can carry out the wear-thickness detection that has.
Background technology
Vacuum circuit-breaker is as the common apparatus in the High-Voltage Electrical Appliances control appliance, in the middle of prior art, widely used, moving contact and fixed contact that its vacuum extinction is indoor belong to easy-abrasion part, and the wear-thickness of moving contact and fixed contact will be directly connected to the useful life of equipment.The user of this kind equipment relies on existing experience to judge the wear-thickness of moving contact and fixed contact in the middle of prior art, if data just must be pulled down vacuum interrupter and observe measurement accurately, cumbersome, time-consuming, inefficiency operate.
Utility model patent " vacuum interrupter electric life tester " has been invented a kind of tester for test vacuum interrupter electric life, although this tester can be finished the test job of vacuum interrupter electric life, this tester exists complex structure, uses the weak points such as inconvenient operation, manufacturing cost height.Need badly in the middle of the prior art and want a kind of vacuum circuit-breaker that can effectively address the above problem.
Summary of the invention
For the deficiencies in the prior art and defective, technical problem to be solved in the utility model is: provide a kind of simple in structure, cost is lower, can observe at any time the vacuum circuit-breaker with electronic type contact abrasion thickness detecting device of contact abrasion thickness.
The purpose of this utility model is achieved in that
Vacuum circuit-breaker with electronic type contact abrasion thickness detecting device, it is characterized in that: comprise wire outlet seat, vacuum interrupter, fixed contact, moving contact, insulating cylinder, lower wire outlet seat, rigid insulation pull bar, displacement transducer, transmission yoke plate, overtravel spring, liquid crystal indicator, operating mechanism, shell body, signal processor, described upper wire outlet seat and lower wire outlet seat are installed on respectively outer upper and the outer lower portion of insulating cylinder; Described fixed contact and moving contact are installed on the vacuum extinction chamber interior, and the lower end of moving contact is fixedly connected with the rigid insulation pull bar; Described rigid insulation pull bar links to each other with the transmission yoke plate by output; Described displacement transducer links to each other with output, and displacement transducer is connected with signal processor by data wire; Described transmission yoke plate and operating mechanism are equipped with the overtravel spring; Described shell body is provided with liquid crystal indicator.
Described overtravel spring fitting is between rigid insulation pull bar and transmission yoke plate.Described displacement transducer will be transferred to signal processor via data wire by the detection signal of telecommunication that on/off switch produces, and demonstrate wear-thickness and on/off switch data through after the signal processor processes by the liquid crystal indicator on the shell body.
By above-mentioned design, the utility model can bring following beneficial effect: the utility model is simple in structure, changes a little on the vacuum circuit-breaker of existing various models and just can use.Be about to the overtravel spring displacement position in the insulated tension pole on the former vacuum circuit-breaker, be placed between connector and the operating mechanism final drive shaft, former insulated tension pole becomes the rigid insulation pull bar.Owing to be to be rigidly connected between detection signal output and the moving contact, so the relative displacement of detection signal output has directly reflected the abrasion condition of dynamic and static contact.The relative displacement of detection signal output can show by liquid crystal indicator, thereby gets information about the wear-thickness of dynamic and static contact, also can observe simultaneously opening apart from value, on/off switch speed and time of vacuum circuit-breaker.The utlity model has the advantages such as simple in structure, that but cost is lower, the wear-thickness of easy enforcement online observation contact, and easy to maintenance, detection data are comprehensive, have promotional value.
