Abstract
The utility model relates to the technical field of a displacement sensor and especially relates to a displacement sensor that is high in precision. The displacement sensor comprises a fixed stand that can be arranged on a pedestal of a breaker, an epoxy plate disposed on the fixed stand, a housing and a top cover that matches the housing. The epoxy plate is positioned between the fixed stand and the housing. A resistor body and a brush seat are arranged in the housing. The brush seat is equipped with a brush. A rubber bar for reinforcing the resistor body is arranged between the housing and the resistor body. The resistor body is connected with a connecting wire that exhibits a shielding effect. The displacement sensor has a simple structure, is capable of measuring signals of the breaker more accurately, is high in reliability, enables interference of other signals to be shielded, enables safety of the breaker to be enhanced and allows the work efficiency to be improved.
Description
Technical field
The utility model relates to the technical field of displacement transducer, especially a kind of high-precision displacement transducer.
Background technology
Displacement transducer is a kind of sensor of measuring the moving contact of breaker displacement that designs on the basis that absorbs domestic and international advanced technology, can be used on the multiple isolating switchs such as VS1, VL1.
The displacement transducer that uses is not accurate to the measurement of breaker signal at present, and reliability is relatively poor, so just influences the work of isolating switch easily, has reduced work efficiency.
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 high-precision displacement transducer is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of displacement transducer, comprise the holder that can be installed on the isolating switch base, be arranged on epoxy plate, the housing on the holder and the loam cake that is complementary with housing, described epoxy plate is between holder and housing, resistive element and brushgear housing are installed in housing, brushgear housing is provided with brush, be provided with between described housing and the resistive element for the rubber strip of reinforcing resistive element, be connected with the connecting line with shielding action on the resistive element.
The making material of described housing is aluminium section bar.
Described holder, epoxy plate are fixedlyed connected by screw with housing.
The beneficial effects of the utility model are: the utility model is simple in structure, can measure the signal of isolating switch more accurately, and reliability is higher, and shields the interference of other signals, has increased the security of isolating switch, has improved work efficiency.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Among the figure: 1. holder, 2. epoxy plate, 3. housing, 4. resistive element, 5. brushgear housing, 6. brush, 7. rubber strip, 8. connecting line.
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.
Displacement transducer as shown in Figure 1, comprise the holder 1 that can be installed on the isolating switch base, be arranged on epoxy plate 2, the housing 3 on the holder 1 and the loam cake that is complementary with housing 3, epoxy plate 2 is between holder 1 and housing 2, resistive element 4 and brushgear housing 5 are installed in housing 3, brushgear housing 5 is provided with brush 6, be provided with between housing 3 and the resistive element 4 for the rubber strip 7 of reinforcing resistive element 4, be connected with the connecting line 8 with shielding action on the resistive element 4, the making material of housing 3 is aluminium section bar, and holder 1, epoxy plate 2 and housing 3 are fixedlyed connected by screw.
Have connecting hole on the brushgear housing 5, have chute hole with the corresponding position of connecting hole on the housing 3, the insulated tension pole of isolating switch lower end is connected by being connected bearing pin with transmission crank arm, the external part that connects bearing pin passes the interior brushgear housing 5 of chute hole and displacement transducer and is connected, when transmission crank arm drives insulated tension pole up and down during divide-shut brake, brushgear housing 5 also drives brush 6 and moves up and down, because brush 6 contacts with resistive element 4, so resistive element 4 data have change, data are transferred on the intelligent breaker monitoring modular by connecting line, chip analysis through intelligent breaker monitoring modular inside, after the processing, the displacement curve of measuring is transferred on the outside display device, and the staff can judge the course of action of contact of breaker according to displacement curve.
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.
