Description
Technical field
The utility model relates to a kind of on-line measuring device, particularly a kind of high-pressure vacuum switch mechanical property on-line measuring device.
Background technology
Vacuum interrupter, has another name called vacuum switch tube, is the core component of mesohigh power switch, and its Main Function is, by can blow-out suppress electric current rapidly after managing the excellent insulativity of interior vacuum and making mesohigh circuitry cuts power supply, avoids accident and to occur unexpectedly.Before vacuum interrupter comes into operation, usually need to detect its mechanical property, at present, conventional detection mode is fixedly connected with a slide rheostat by the moving conductive rod of vacuum interrupter, then the athletic meeting of the moving conductive rod of vacuum interrupter changes the resistance of described slide rheostat, thus obtain the working value of vacuum interrupter, but due to slide rheostat be contact, in testing process, have wearing and tearing to a certain degree, affect the serviceable life of pick-up unit; In addition, the on-line checkingi of mechanical property cannot be realized with upper type, for speed, open the parameters such as distance, the excess of stroke and cannot detect.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of structure simple high-pressure vacuum switch mechanical property on-line measuring device, and it can firm conjunction, the just branch of the indoor dynamic and static contact of on-line checkingi vacuum extinction, understands the degree of wear of dynamic and static contact.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of high-pressure vacuum switch mechanical property on-line measuring device, it is characterized in that: comprise frame, insulator, link gear and displacement transducer, described insulator is fixedly connected with moving conductive rod lower end, vacuum interrupter bottom, displacement transducer is made up of resistive element and brush, resistive element is fixed on interior insulator, brush upper end to be arranged on inside resistive element and vertically to slide inside resistive element, and brush lower end is fixed in frame, and link gear is connected with insulator lower end.
Further, described link gear comprises connecting rod, lever and driving stem, and one end of connecting rod is hinged on driving stem one end, the connecting rod other end and lever one end hinged, the other end of lever is fixedly connected with insulator lower end.
Further, the upper end of described vacuum interrupter is provided with wire outlet seat, and the lower end of vacuum interrupter is provided with connecting hose.
The utility model compared with prior art, have the following advantages and effect: high-pressure vacuum switch mechanical property on-line measuring device structure is simple, reduce cost, and it is reliable, can firm conjunction, the just branch of the indoor dynamic and static contact of on-line checkingi vacuum extinction, understand the degree of wear of dynamic and static contact, complete function.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of high-pressure vacuum switch mechanical property on-line measuring device of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
As shown in Figure 1, high-pressure vacuum switch mechanical property on-line measuring device of the present utility model comprises frame 1, insulator 2, link gear and displacement transducer, insulator 2 is fixedly connected with moving conductive rod lower end, vacuum interrupter 3 bottom, displacement transducer is made up of resistive element 4 and brush 5, it is inner that resistive element 4 is fixed on insulator 2, brush 5 upper end to be arranged on inside resistive element 4 and vertically to slide inside resistive element 4, brush 5 lower end is fixed in frame 1, and link gear is connected with insulator 2 lower end.The utility model utilizes displacement sensor to convert the change in displacement between insulator 2 and link gear to electricity and exports, and utilize the change of this electricity output valve to obtain firm conjunction, the just branch of dynamic and static contact in vacuum interrupter 3, thus understand the degree of wear of dynamic and static contact.
Link gear comprises connecting rod 6, lever 7 and driving stem 8, and one end of connecting rod 6 is hinged on driving stem 8 one end, connecting rod 6 other end and lever 7 one end hinged, the other end of lever 7 is fixedly connected with insulator 2 lower end.The other end of driving stem 8 is fixed in the rotating shaft of external motor, such external motor drives driving stem 8 to rotate, thus carry out activation lever 7 rotate up and down along lever shaft by driving stem 8 drivening rod 6 rotated, thus the moving conductive rod of vacuum interrupter 3 is driven to move up and down the folding controlling vacuum interrupter dynamic/static contact.The upper end of vacuum interrupter 3 is provided with wire outlet seat 9, the lower end of vacuum interrupter 3 is provided with connecting hose 10, external unit is utilized to be connected with connecting hose 10 by described upper wire outlet seat 9, itself and vacuum interrupter 3 is made to form loop, can reflect that the state in vacuum interrupter 3 residing for dynamic and static contact is closed or separates according to the break-make road of external unit, be convenient to the firm conjunction, the just branch that find dynamic and static contact.
Above content described in this instructions is only made for the present invention illustrating.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of instructions of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
