Abstract
Description
Technical Field
[0001] The invention relates to the technical field of combined electrical appliances, and in particular to a switch operating force measuring device. Background Art
[0002] Regarding the maximum force requirements for manual operation of high-voltage switchgear, Article 6.105 of the GB / T1985-2023 High-voltage AC disconnectors and earthing switches standard stipulates that the maximum force required to operate a disconnector or earthing switch that requires more than 1 turn (such as a manual crank) or stores energy should not exceed 120N, and should not exceed 80N within 90% of the total number of turns required; the force required to operate or store energy for a disconnector or earthing switch that requires less than 1 turn (such as a rocker) should not exceed 250N, and within the range of a maximum rotation angle of 15°, the maximum allowable value is 450N. Article 6.6.4 of the GB / T11022-2020 Common Technical Requirements for High-voltage AC Switchgear and Control Equipment Standards stipulates that the maximum operating force required to store energy in a spring (or heavy hammer) by manpower should not exceed 250N.
[0003] Generally, manual closing and opening of disconnectors require human operation, and manual energy storage of circuit breakers requires human operation. The force measuring devices currently used can measure the operating force value, but cannot measure the number of operating turns and angles. When the operating force of disconnectors that require more than one turn exceeds 80N but does not exceed 120N, it is impossible to determine whether it meets the standard requirements due to the lack of measurement of the number of operating turns and angles. Summary of the invention

[0006] Furthermore, the switch operating force testing system performs human-computer interaction through a touch screen, and torque, operating force and angle data are displayed in curves, and the maximum operating force and total rotation angle are displayed in a table; the test data can be exported, analyzed by the host computer software, and an EXCEL raw data form can be produced.
[0007] Furthermore, the measurement range of the torque sensor is: 0-200N.m.
