Therefore, in the process of stretching the spring by the limiting pieces, the stretching path of the spring and the two corresponding limiting pieces are kept on the same horizontal plane, the process of stretching the spring by the limiting pieces and the measurement of the spring by the spring dynamometer are improved, and errors generated in the measurement process of the spring dynamometer are reduced.

Description

technical field [0001] The invention belongs to the field of isolation switch detection, in particular to an isolation switch output shaft rotation angle measurement system used for online monitoring. Background technique [0002] The isolating switch is a component used in industrial equipment to realize the disconnection and connection of the circuit. In the prior art, the isolating switch is made of shaft pins, bearings, springs and other components, and the rotation of the shaft pins realizes the connection of the circuit. In the on or off state, the rotation of the shaft pin and the reset action are realized through the elastic action of the spring. In the prior art, the on-line measurement of the rotation angle of the isolating switch is particularly important, and the result of the on-line measurement directly determines the accuracy of the isolating switch in practical applications. In fact, the rotation angle measurement of the isolator is achieved by measuring the...

Problems solved by technology

[0003] In the prior art, there are many measuring devices and methods for the spring in the isolating switch. Among them, the publication number is CN110082051B, which discloses a spring automatic detection device, which includes a detection platform, and the upper end of the detection platform is fixedly connected with two vertical support plates. , the two supporting plates are respectively located on both sides of the upper end of the testing platform, and two vertical moving plates are arranged between the two supporting plates, T-shaped chutes are opened at the opposite ends of the two moving plates, and the two A set of T-shaped sliders are slidably connected to the inside of each T-shaped chute, and the two ends of each group of T-shaped sliders are located outside the T-shaped chute and are fixedly connected with L-shaped rods. The ends are oppositely set, and the inside of the T-shaped chute is provided with a vertically arranged two-way threaded rod. Although the spring automatic detection device involved in the above patent is easy to operate and can be protected during detection, it can prevent the spring from breaking and popping up to cause harm to the human body. However, when the detection device detects the spring, during the detection process of the detection spring, the two-way threaded rods at both ends cannot accurately control the distance that the two-way threaded rod drives the L-shaped rod to move during the twisting process, so that the two The corresponding L-shaped rods on the two-way threaded rods are not located on the same horizontal plane, which leads to deviations in the results of the spring dynamometer when the spring dynamometer detects the spring, which further leads to the disadvantage of errors in the spring diagnosis results. Therefore, it is necessary to design a measurement system for the output shaft rotation angle of the disconnector that can realize spring fixing to improve the detection results.
