Abstract
The invention relates to the technical field of high-voltage switch assembly, in particular to a device for measuring the pressure of a moving contact and a fixed contact of a high-voltage switch. The device comprises a base plate, a tension gauge, a pull rod and a clamping force measuring rod, wherein the tension gauge is arranged in a tension gauge fixing groove on the surface of the base plate; a dynamometer link of the tension gauge is connected with one end of the pull rod through a movable shaft, and the other end of the pull rod is connected with the clamping force measuring rod through a movable shaft; and the clamping force measuring rod is connected with and fixed on the surface of the base plate through a movable shaft. The data measured by the device is analog data, and is comparatively ideal to serve as comparative data of pressures of contacts with the same specification; and the device is small in volume and light in weight, is convenient to carry, is particularly suitable for detection, examination and repair of a narrow space in a switch cabinet, is small in data error of repeated measurements, is simple in structure and can be easily operated.
Description
Technical field
What technology of the present invention related to is high-voltage switch gear mounting technology field, is specially high-voltage switch gear dynamic/static contact device for pressure measurement.
Background technology
During the assembling of three-phase high-voltage switch, the alternate error of definite value sum of errors of three-phase contact pressure need be controlled within the specific limits.Generally use the measurement mechanism of pull and push dynamometer in the market as high-voltage switch gear dynamic/static contact pressure; But this device can only be measured the pressure that dynamic/static contact is the switch contact of single face contact; And be the switch of two-sided clip close contact for some moving contacts or static contact; Just need measure the clamping force (contact pressure) of clamp contact, common pull and push dynamometer is powerless.
Summary of the invention
The purpose of this invention is to provide a kind of measurement mechanism that can measure high-voltage switch gear dynamic/static contact pressure simultaneously.
To achieve these goals; Technical solution of the present invention is: high-voltage switch gear dynamic/static contact device for pressure measurement; Comprise base plate, tautness meter, pull bar, clamping force sounding rod, tautness meter is arranged in the tautness meter pickup groove on the base plate face, and the tautness meter dynamometer link is connected with an end of pull bar through movable axis; The other end of pull bar is connected with the clamping force sounding rod through movable axis, and the clamping force sounding rod connects through movable axis and is fixed on the base plate face.
Described base plate, pull bar, clamping force sounding rod are all processed by the 3mm corrosion resistant plate.
Described floor length is 35cm, and the widest part is 12cm, and the narrowest place is 9cm.
Described clamping force sounding rod is two L type members that are symmetric figure.
The angle on two limits of described clamping force sounding rod is the right angle, and length is 6cm.
Affiliated movable axis is the high charcoal steel workpiece of diameter 8mm.
The maximum range of described tautness meter is 25kg.
During work; The clamp contact gap is stretched on the top of clamping force sounding rod, pulling tautness meter handle, treat that clamp contact opens after; Convert the clamping force that is delivered to the clamp contact on the clamping force sounding rod pulling force of handle to through pull bar, show pulling force numerical value through tautness meter; All movable axis had both guaranteed can guarantee that again web member rotates freely outside the reliable connection of web member.
Adopting data that this device is surveyed is simulated data, comparatively desirable as the correlation data of same model contact pressure; This device volume is little, in light weight, is easy to carry, and is particularly suitable for the detection maintenance of small space in the switch cubicle, and the repeated measurement data error is less, simple in structure, processing ease.
