Description
Technical field
The utility model relates to the technical field of the device of measuring contact of breaker, especially a kind of power sensor of novel measurement contact of breaker.
Background technology
In traditional breaker mechanic property is measured, must guarantee that isolating switch is in off-line state, and needing provides a small loop current to it, by the break-make of electric current judge contact of breaker deciliter, thereby obtain the firm chalaza of firm branch, the shortcoming of Ce Lianging is to operate comparatively loaded down with trivial detailsly like this, and can't realize on-line measurement.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of power sensor of novel measurement contact of breaker is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of power sensor of novel measurement contact of breaker, between insulated tension pole and transmission crank arm, comprise the power sensor holder, foil gauge, the power sensor board, shrouding, one end of described power sensor holder is provided with the axial columns that is connected with insulated tension pole, the other end of power sensor holder has the radial hole that is connected with transmission crank arm, both sides between axial columns and the radial hole respectively have groove, be provided with through hole between the groove, only be provided with foil gauge in the groove, be provided with foil gauge in another groove, the power sensor, connect by through hole between the foil gauge, be connected with the power sensor again, also have the through wires hole that communicates with groove on the described power sensor holder, the power sensor is connected with outside by through wires hole.Described shrouding matches with groove.
Described insulated tension pole is threaded with axial columns.
Described transmission crank arm is threaded with radial hole.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy to operate, and realized on-line measurement, and it is accurate, reliable to measure.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is front view of the present utility model;
Fig. 2 is partial sectional view of the present utility model;
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1. power sensor holder, 1-1. axial columns, 1-2. radial hole, 1-3. groove, 1-4. through hole, 1-5. through wires hole, 2. foil gauge, 3. shrouding, 4. power sensor board.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The synoptic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Embodiment: the power sensor of novel measurement contact of breaker as shown in Figure 1, between insulated tension pole and transmission crank arm, comprise power sensor holder 1, foil gauge 2, power sensor board 4, shrouding 3, one end of described power sensor holder 1 is provided with the axial columns 1-1 that is connected with insulated tension pole, the other end of power sensor holder 1 has the radial hole 1-2 that is connected with transmission crank arm, both sides between axial columns 1-1 and the radial hole 1-2 respectively have groove 1-3, be provided with through hole 1-4 between the groove 1-3, described groove 1-3 bottom respectively is equipped with a foil gauge 2, connect by through hole 1-4 between the foil gauge 2, be connected to afterwards on the power sensor board 4 in one of them groove 1-3, also have the through wires hole 1-5 that communicates with groove 1-3 on the described power sensor holder 1, the data line of power sensor board 4 is connected to outside isolating switch monitoring means by through wires hole 1-5, with shrouding 3 groove 1-3 is sealed afterwards.
When work, transmission crank arm is moved up or down, driving insulated tension pole moves up or down, contact of breaker closes thereupon or separates, in this process, power sensor holder 1 also is subjected to power up or down, thereby generation deformation, after foil gauge 2 in the groove 1-3 is sensed the deformation of power sensor holder 1, its resistance will change thereupon, thereby the voltage that changes, the voltage that changes is through the amplification of exertin sensor board 4, after the filtering, connecting line by the power sensor is transferred to outside isolating switch monitoring means, passes through the analysis of the data processing module in the isolating switch monitoring means again, after the processing, judge the size of contact of breaker pressure, can judge the firm chalaza of firm branch of contact of breaker according to the situation of change of the size of pressure, thereby realized the purpose that the firm branch of real time on-line monitoring isolating switch device contact has just closed, and measurement result is accurate, easy to use.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
