Abstract
The utility model relates to a device for detecting stroke of a high pressure switch fitted with a hydraulic mechanism, comprising a connecting block provided with a transverse chute, a crank arm, a frame, an elastic coupler and an angular displacement sensor, wherein the connecting block is arranged at a lower portion of a moving contact, one end of the crank arm is extended into the chute via a pin and is movably connected with the connecting block, the other end of the crank arm is vertically and fixedly connected with a connecting rod, the other end of the connecting rod is connected with the angle displacement sensor via the elastic coupler, the angle displacement sensor is fixed on the frame, and the angle displacement sensor is connected with an acquisition processor via a circuit. The device can transit linear motion to rotary motion, and then can detect the rotation angle via the angle displacement sensor. The device is small in size, low in cost and precise in detection.
Description
Technical field
The utility model relates to a kind of device for detecting distance of travel, specifically a kind of device for detecting distance of travel of high-voltage switch gear of adapted hydraulic mechanism.
Background technology
High-voltage switch gear to the adapted hydraulic mechanism carries out stroke detection, divide-shut brake characteristic that can the analysis and judgement switch, the performance of mechanism, so stroke detection is very necessary.Because the responsiveness of switchgear reaches 3～10 meter per seconds, stroke adopts linear movement pick-up to detect at 200 millimeters, receives the restriction of mechanism structure size and responsiveness, can't realize.
Summary of the invention
The utility model for overcome above-mentioned defective provide a kind of structure small and exquisite, with low cost, detect the device for detecting distance of travel of the high-voltage switch gear of adapted hydraulic mechanism accurately.
The technical scheme that the utility model adopts is: a kind of device for detecting distance of travel of high-voltage switch gear of adapted hydraulic mechanism; Comprise contiguous block, connecting lever, frame, spring coupling and the angular displacement sensor of being with horizontal concrete chute; Described contiguous block is arranged on the bottom of moving contact; Connecting lever one end extend into through bearing pin in the chute of contiguous block with contiguous block for flexibly connecting, the other end of connecting lever is connected with the connecting link vertical fixing, the other end of connecting link passes through spring coupling and is connected with angular displacement sensor; Angular displacement sensor is fixed on the frame, and angular displacement sensor connects through circuit and is connected with Acquisition Processor.
The bottom that contiguous block is arranged on moving contact of the utility model; Be connected with angular displacement sensor through connecting lever and spring coupling then; Like this when the upper and lower motion of moving contact, be i.e. during divide-shut brake action, just the rectilinear motion of organization switch stroke converted into and rotatablely move; Utilize angular displacement sensor that the anglec of rotation is detected; Then data message is sent to Acquisition Processor, compares and handle with the information that prestores in the Acquisition Processor, thereby the stroke of switch divide-shut brake is detected.The utility model converts rectilinear motion into and rotatablely moves, and then utilizes angular displacement sensor that the anglec of rotation is detected, and this stroke detection structure has characteristics such as structure is small and exquisite, with low cost, detection is accurate.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Fig. 2 is that the A of Fig. 1 is to figure.
Embodiment
Combine accompanying drawing that the utility model is further described, Fig. 1 is a kind of embodiment of the utility model at present, comprises contiguous block 1, connecting lever 2, frame 3, spring coupling 4 and the angular displacement sensor 5 etc. of being with horizontal concrete chute.Described contiguous block 1 is arranged on the bottom of moving contact 7; One end of connecting lever 2 extend into through bearing pin in the chute of contiguous block 1 and with contiguous block 1 for flexibly connecting; The other end of connecting lever 2 is connected with connecting link 8 vertical fixing; The other end of connecting link 8 is connected with angular displacement sensor 5 through spring coupling 4, and angular displacement sensor 5 is fixed on the frame 3, and angular displacement sensor 5 connects through circuit and is connected with Acquisition Processor 6.
During use, the moving contact 7 of the utility model drives contiguous block 1 and makes rectilinear motion up and down when divide-shut brake moves; Contiguous block 1 just drives connecting lever 2 through bearing pin and rotates; Because connecting lever 2 is connected with angular transducer 5 through connecting link 8 and spring coupling 4, therefore angular transducer 5 just can detect the data message of connecting lever 2 rotational angles, and angular transducer 5 is sent to Acquisition Processor 6 with detected data message again; Compare and handle with the data message that prestores in the Acquisition Processor 6; It is excessive to cross the stroke that stool explanation switch moves up and down like rotational angle, if rotational angle is too small, just explain that the stroke that switch moves up and down is too small; Whether the stroke that can judge the switch divide-shut brake like this is in the scope of regulation; So that adjust, thereby guarantee the best stroke of high-voltage switch gear divide-shut brake, improve the transmission capacity and the stability of equipment.
The utlity model has characteristics such as structure is small and exquisite, with low cost, detection is accurate.
