The utility model relates to the technical field of breaker equipment and especially provides a switching-on and switching-off device of a piezoceramic transducer measurement breaker, which comprises a body, an insulating pull bar and a transmission connecting lever. The insulating pull bar and the transmission connecting lever are arranged at the lower part of the body. The lower end of the insulating pull bar is provided with a piezoceramic transducer. The side edge of the piezoceramic transducer is fixedly connected with a displacement sensor. The switching-on and switching-off device of the piezoceramic transducer measurement breaker has the advantages of simple structure, fast measurement speed, sensitive response, better reliability and higher work efficiency, which can accurately measure the switching-on point and the switching-off point of the breaker.

Description

Piezoceramic transducer is measured the device that the firm branch of isolating switch has just closed
Technical field
The utility model relates to the technical field of breaker apparatus, and especially a kind of piezoceramic transducer is measured the device that the firm branch of isolating switch has just closed.
Background technology
In existing technology, for measure method that isolating switch just divides, just closed have a variety of, but there is following shortcoming in its result who measures: degree of accuracy is not high, and the measuring speed reaction is slower, can not judge firm branch and just chalaza exactly.
The utility model content
The technical matters that the utility model will solve is: overcome the deficiency in the prior art, provide a kind of piezoceramic transducer to measure the device that the firm branch of isolating switch has just closed.
The utility model solves the technical scheme that its technical matters adopted: a kind of piezoceramic transducer is measured the device that the firm branch of isolating switch has just closed; Comprise body, be installed in the insulated tension pole and the transmission crank arm of body below; The lower end of described insulated tension pole is provided with piezoceramic transducer, is fixedly connected with displacement transducer at the side of piezoceramic transducer.
Described piezoceramic transducer is connected through bolt with insulated tension pole.
Described piezoceramic transducer is fixedly connected through pin with displacement transducer.
All be provided with on described piezoceramic transducer and the displacement transducer and be used for the outwards connecting line of output.
The beneficial effect of the utility model is: the utility model is simple in structure, can measure the firm branch and firm chalaza of isolating switch accurately, and measuring speed is very fast, is quick on the draw, and reliability increases, and has improved work efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. body, 2. insulated tension pole, 3. transmission crank arm, 4. piezoceramic transducer, 5. displacement transducer.
Embodiment
Combine accompanying drawing and preferred embodiment that the utility model is further described now.These accompanying drawings are the synoptic diagram of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of piezoceramic transducer as shown in Figure 1 is measured the device that the firm branch of isolating switch has just closed; Comprise body 1, be installed in the insulated tension pole 2 and the transmission crank arm 3 of body 1 below; The lower end of insulated tension pole 2 is connected with piezoceramic transducer 4 through bolt; Side at piezoceramic transducer 4 is fixedly connected with displacement transducer 5 through pin, all is provided with on piezoceramic transducer 4 and the displacement transducer 5 to be used for the outwards connecting line of output.
Above-mentioned piezoceramic transducer measure device that the firm branch of isolating switch just closed for the firm branch of isolating switch just closed measuring method, the steps include:
(1), transmission crank arm is started working drive piezoceramic transducer and displacement transducer motion;
(2), in motion process, piezoelectric ceramics receives power, power makes that in the process that changes piezoceramic transducer produces piezoelectric signal, the displacement of brush makes displacement transducer produce displacement signal;
(3), be transferred in the CPU after the amplification of piezoelectric signal and displacement signal process, the filtering;
(4), after the DMA synchronized sampling of amplification, filtered piezoelectric signal and displacement signal process CPU, noise reduction, the processing; Obtain isolating switch branch, combined floodgate displacement curve and isolating switch and just divided just fashionable, thus calculate separating brake and the combined floodgate of isolating switch time, speed, open the mechanical property of isolating switchs such as the distance and the excess of stroke.
(5), the data presentation that calculates also is stored on the intelligent breaker monitoring means.
Piezoelectric ceramics has responsive characteristic; Can convert extremely faint mechanical vibration to electric signal, and can in the time of tens microseconds, make response fast, reaction velocity is fast; In the utility model; Utilize its susceptibility and react the firm chalaza of firm branch that rapidity is measured isolating switch, combine displacement transducer that the displacement curve of contact of breaker is monitored again, just divided the accurate judgement of firm chalaza to have crucial meaning to isolating switch undoubtedly.
The foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
