Abstract
The utility model discloses a three-station isolation switch position sensing device. The device comprises a rotating shaft driven by a main shaft of an isolating switch, a position indicating dial capable of synchronously rotating together with the rotating shaft is arranged on the rotating shaft, a fixing plate is arranged above the position indicating dial, position sensors capable of detecting a detection point on the position indicating dial are distributed on the fixing plate, the fixing plate is provided with at least one adjusting block capable of carrying out adjustment on the fixing plate, at least one sensor is installed on the adjusting block, the adjusting block is provided with a through hole, and sensing signals of the sensors are enabled to pass through the through hole to detect the detection point on the position indicating dial by adjusting the position of the adjusting block on the fixing plate. Due to the adoption of the structure, when the position is not accurate, the position of the adjusting block on the fixing plate can be adjusted, and sensing signals of the sensors are enabled to pass through the through hole to detect the detection point on the position indicating dial after position adjustment. Thereby, the sensing accuracy is improved, the reliability of operation is improved, and the using performance is ensured.
Description
Technical field
The utility model relates to a kind of tri-station isolating switch position sensing device, belongs to mesohigh power transmission and distribution technical field.
Background technology
All be provided with the sensing device for position probing in existing tri-station isolating switch; but existing sensing device is unreasonable because structure arranges; usually can not reach due to the actual machining accuracy of the workpieces such as gear, panel beating the situation of theoretic required value; same batch products particularly; if the platform amount is more; can exist closing position and the position of indivedual three-stations accurate not; after causing mechanism to put in place accurately signal transmission to proximity transducer; make thus sensing accuracy poor; operational reliability reduces, and has affected the product serviceability.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can improves sensing accuracy, improves operational reliability, thereby guarantees the tri-station isolating switch position sensing device of serviceability.
In order to solve the problems of the technologies described above, tri-station isolating switch position sensing device of the present utility model, comprise the rotation axis driven by the isolating switch main shaft, on rotation axis, be provided with can with the position indicating dial of rotation axis synchronous rotary, indicating dial top, position is provided with fixed head, be distributed with the position transducer that test point on the indicating dial of position can be detected on fixed head, at least be provided with the regulating block that can be regulated on fixed head on fixed head, has an installation of sensors at least on regulating block, be provided with through hole on regulating block, by regulating regulating block, in the position of fixed head, can make the transducing signal of transducer test point on the indicating dial of position be detected through through hole.
Be provided with the arc guide barrel that is positioned at the transducer both sides on described regulating block, the axle center of arc guide barrel and rotation axis is the center of circle, is provided with the spacer pin be fixedly mounted on fixed head in arc guide barrel, and described spacer pin coordinates and is pressed abd fixed on fixed head by nut.
Described regulating block is set to fan-shaped.
After adopting above-mentioned structure, due to the regulating block that can be regulated on fixed head arranged, thus can be by regulating the position of regulating block at fixed head when position is inaccurate, when making the transducing signal of transducer see through through hole later, the position adjustment test point on the indicating dial of position detected, improved thus sensing accuracy, improve operational reliability, thereby guaranteed serviceability.
