On described header board, be designed with mechanism's state indication component, it comprises is fixed on the direction board of direction board axle through the end, one end of header board, design the Warning Mark on output board, corresponding to output shaft rotation to combined floodgate, separating brake, earthing position, be opened on header board, front dividing plate, rear bulkhead for on output board, corresponding to output shaft rotation to combined floodgate, separating brake, ground connection mark and be positioned at before and after mechanism's state observation window on straight line.
The high voltage isolator three station list spring manual double-shaft operating mechanisms that the invention process obtains are as follows in the operating process of three stations:
Separating brake station: as shown in Fig. 3,4,5, in figure, the axial gap of on/off switch operating axis, ground connection operating axis is in the upper left that coexists, energy-stored spring is in energy storage state not, the predetermined angular β in the fan-shaped arc hole of offering on the predetermined angular α in the fan-shaped arc hole that output board is offered, drive plate is all in original position, direction board upwards, locking disc edge on its axle shelters from a part for on/off switch operating axis operating side, cannot use specific purpose tool to butt up against on/off switch operating axis, on/off switch operating axis is blocked.
Combined floodgate station: as Fig. 6, 7, shown in 8, with manually stirring counterclockwise direction board to downwards, drive the locking disc on its axle to turn over the part that shelters from on/off switch operating axis operating side, expose on/off switch operating axis operating side, use specific purpose tool to butt up against on/off switch operating axis, rotate counterclockwise on/off switch operating axis energy-stored spring is carried out to energy storage, because output board offers the predetermined angular α in fan-shaped arc hole, on drive plate, offer the predetermined angular β in fan-shaped arc hole, on/off switch operating axis drives driving shaft to walk idle running, output shaft, ground connection operating axis is all motionless, on/off switch operating axis rotates while reaching predetermined angular α, now energy-stored spring arrive energy storage to discharge critical point time, energy storage to the energy-stored spring of maximum flexibility potential energy impels on/off switch operating axis to continue to rotate to closing position under elastic restoring force drives, thereby drive output shaft quick rotation to closing position, on/off switch latch plate in this process on on/off switch operating axis is interfered direction board latch plate, drive periphery on direction board axle and turn to edge and block the part of ground connection operating axis operating side near the locking disc of header board, ground connection operation is blocked.
Ground connection station: carrying out, before ground connection operation, clockwise rotating in advance ground connection operating axis, carry out the process by close a floodgate separating brake station contrary with closing operation process, be returned to the position as shown in Fig. 3,4,5, then use specific purpose tool to butt up against ground connection operating axis, as Fig. 9, 10, shown in 11, rotate counterclockwise ground connection operating axis energy-stored spring is carried out to energy storage, because output board offers the predetermined angular α in fan-shaped arc hole, on drive plate, offer the predetermined angular β in fan-shaped arc hole, ground connection operating axis drives driving shaft to walk idle running, output shaft, ground connection operating axis is all motionless, ground connection operating axis rotates while reaching predetermined angular β, now energy-stored spring arrive energy storage to discharge critical point time, energy storage to the energy-stored spring of maximum flexibility potential energy impels ground connection operating axis to continue to rotate to earthing position under elastic restoring force drives, thereby drive output shaft quick rotation to closing position, ground connection latch plate in this process on ground connection operating axis is interfered direction board latch plate, drive periphery on direction board axle and turn to edge and block the part of on/off switch operating axis operating side near the locking disc of header board, closing operation is blocked.
The high voltage isolator three station list spring manual double-shaft operating mechanisms that the invention process obtains, have compared with prior art shown following beneficial effect through trying out:
1, without separately establishing output shaft and linkage, share 1 energy-stored spring, designs simplification, volume-diminished.Than the high voltage isolator three station hand-operated operating mechanisms of prior art of separately establishing output shaft and linkage, the three-axis structures such as the output shaft that is provided with on/off switch operating axis, ground connection operating axis in its mechanism and could link by linkage are simplified to and are directly connected in coaxial output shaft by on/off switch operating axis through coaxial driving shaft, thereby complete the combined floodgate station of high voltage isolator, the manual operation of separating brake station; Ground connection operating axis is operated to axle sleeve-ground connection operation drive plate-doubly-linked plate-output board through ground connection and be connected in output shaft, thereby complete the manual operation of the ground connection station of high voltage isolator.Be reduced to diaxon by three axles; The present invention is connected in energy-stored spring dexterously between on/off switch operating axis and ground connection operating axis in structure, utilize the variation of position, an energy-stored spring two, obtain combined floodgate, separating brake, ground connection and operate needed energy-stored spring elastic potential energy, high voltage isolator three station hand-operated operating mechanisms than prior art arrange respectively combined floodgate, separating brake, ground connection operates needed two energy-stored springs, be reduced to and only need 1 spring by two springs, obviously designs simplification, volume-diminished.
2, without configuring in addition blocking mechanism, not only there are high voltage isolator three station manipulation functions, and possess blocking function simultaneously.Configure in addition the high voltage isolator three station hand-operated operating mechanisms of the prior art of blocking mechanism than needs, the present invention in mechanism directly at on/off switch operating axis, on ground connection operating axis, be coaxially provided with on/off switch latch plate, ground connection latch plate, direction board latch plate and the locking disc of direction board axle and coaxial linkage between diaxon, are configured, use on/off switch latch plate, the corresponding interference of ground connection latch plate and direction board latch plate, the involutory sub-switching operation of locking disc hole, blocking of ground connection handle hole, what completed that prior art needs that configuration blocking mechanism in addition just can reach cannot carry out ground connection operation in the time of combined floodgate station, in the time of ground connection station, cannot carry out the mutual blocking function of closing operation.Obviously, the high voltage isolator three station hand-operated operating mechanisms that configure in addition the prior art of blocking mechanism than needs not only self have had blocking function, and must further simplify the structure.
Due to structure designs simplification of the present invention, volume-diminished takes up room and greatly reduces in the time being used in high voltage isolator, can meet the adapted of different size, the different high voltage isolators that require.
