Description
Technical field
The utility model relates to a kind of high speed grounding switch.
Background technology
Need with high speed grounding switch in multiple electric system, as high-voltage electrical equipment be short-circuited fault time, quick crowbar short-circuit current, manufactures network artificial earthing, to guarantee the safety of electric equipment and maintainer.Closing speed is the key property parameter of high speed grounding switch.
Existing high speed grounding switch is made up of underframe, ground connection blade, earthed crank arm, energy-stored spring, rotating shaft, operation connecting lever, support insulator and contact, support insulator is contained on underframe, contact dress on the insulator, rotating shaft is contained on underframe, ground connection blade is fixed on earthed crank arm, earthed crank arm is arranged in rotating shaft, operation connecting lever is arranged on rotating shaft one end, and energy-stored spring is arranged between underframe and earthed crank arm.When grounding switch closes a floodgate, operation connecting lever makes rotating shaft rotate, and drives earthed crank arm action, after crossing energy storage dead point, rotating shaft no longer drives earthed crank arm, is released energy by energy-stored spring, promote earthed crank arm, be grounded blade and contact rapid closing, be namely grounded out quick crowbar short-circuit current.High speed grounding switch due to rotating shaft asynchronous with earthed crank arm, the closing speed of grounding switch is not easily detected.
Utility model content
The purpose of this utility model is a kind of high speed grounding switch closing speed pick-up unit of design.
The utility model high speed grounding switch closing speed pick-up unit, it is characterized in that, comprise an angular displacement sensor and mechanic character tester, high speed grounding switch underframe is fixed with a sensor installing plate, angular displacement sensor is fixed on sensor installing plate, high speed grounding switch earthed crank arm is fixed with a driver plate, in the end of high speed grounding switch rotating shaft, orienting sleeve is housed, orienting sleeve can freely rotate, hexagonal connecting rod wore driver plate and connected orienting sleeve and angular displacement sensor, angular displacement sensor is connected by data line with mechanic character tester.
The high speed grounding switch closing speed pick-up unit that the utility model provides, when high speed grounding switch closes a floodgate, operation connecting lever makes rotating shaft rotate, and drives earthed crank arm action, after crossing energy storage dead point, rotating shaft no longer drives earthed crank arm, is released energy by energy-stored spring, promotes earthed crank arm and driver plate synchronous rotary, driver plate drives hexagonal connecting rod, make angular displacement sensor produce angular deflection, pass to mechanic character tester by data line, realize the closing speed detecting high speed grounding switch.Structure is simple, easy for installation, applied widely.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing high speed grounding switch;
Fig. 2 is the structural representation of the utility model high speed grounding switch closing speed pick-up unit embodiment;
In figure: 1, underframe 2, energy-stored spring 3, rotating shaft 4, operation connecting lever 5, earthed crank arm 6, ground connection blade 7, contact 8, insulator 9, driver plate 10, data line 11, mechanic character tester 12, sensor installing plate 13, angular displacement sensor 14, hexagonal connecting rod 15, orienting sleeve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, the feature of the utility model high speed grounding switch closing speed pick-up unit is, comprise an angular displacement sensor 13 and mechanic character tester 11, high speed grounding switch underframe 1 is fixed with a sensor installing plate 12, angular displacement sensor 13 is fixed on sensor installing plate 12, high speed grounding switch earthed crank arm 5 is fixed with a driver plate 9, in the end of high speed grounding switch rotating shaft 3, orienting sleeve 15 is housed, orienting sleeve 15 can freely rotate, hexagonal connecting rod 14 wore driver plate 9 and connected orienting sleeve 15 and angular displacement sensor 13, angular displacement sensor 13 is connected by data line 10 with mechanic character tester 11.
When high speed grounding switch closes a floodgate, operation connecting lever 4 makes rotating shaft 3 rotate, drive earthed crank arm 5 action, after crossing energy storage dead point, rotating shaft 3 no longer drives earthed crank arm 5, released energy by energy-stored spring 2, promote earthed crank arm 5 and driver plate 9 synchronous rotary, driver plate 9 drives hexagonal connecting rod 14, makes angular displacement sensor 13 produce angular deflection, pass to mechanic character tester 11 by data line 10, realize the closing speed detecting high speed grounding switch.What solve because of rotating shaft and earthed crank arm is asynchronous, makes the difficult problem that the closing speed of high speed grounding switch not easily detects.Structure is simple, easy for installation, applied widely.
