Embodiment Construction
[0021] The present invention is a detection device for a cam of a high-voltage vacuum circuit breaker operating mechanism, which includes a base 1, a detection module 4 and a fixed shaft 3, such as figure 1 and figure 2 Base 1 is shown, as image 3 Shown is the detection module 4, the detection module 4 is installed on the base 1, the detection module 4 has a detection arc surface 6 adapted to the outer arc surface of the cam of the operating mechanism, and the shape of the detection arc surface 6 and the outer arc surface of the cam Similarly, the fixed shaft 3 is installed vertically on the base 1. During detection, the cam is fixed on the fixed shaft 3 through the shaft hole on it. It can be detected whether there is a shaking gap between the cam on the fixed shaft 3 and the outer arc of the cam. Whether there is a gap between the surface and the detection arc surface 6 on the detection module 4 can determine whether the dimensional accuracy of the cam is qualified, the d...

The invention discloses a detection device for a cam of an operating mechanism of a high-voltage vacuum breaker and a detection method of the detection device. The detection device comprises a base, a detection module and a stationary shaft, wherein the detection module is mounted on the base; a detection cambered surface matched with an outer cambered surface of the cam of the operating mechanism is arranged on the detection module; the stationary shaft is vertically mounted on the base; and during detection, the stationary shaft is sleeved with the cam through an axle hole in the cam, and the cam is fixed on the stationary shaft. Compared with the prior art, the detection device is simple in structure and adopts the detection module with the shape matched with that of the cam; according to the detection method, during the detection, whether the dimensional accuracy of the cam is qualified or not is judged by detecting whether a swaying gap between the cam and the stationary shaft exists and whether a gap between the outer cambered surface of the cam and the detection cambered surface of the detection module exists, the detection is convenient and rapid, and the operation is simple.
Description
technical field [0001] The invention relates to detection equipment, in particular to a detection device and a detection method for a cam of an operating mechanism of a high-voltage vacuum circuit breaker. Background technique [0002] As the main control and protection equipment in the power system, the AC high-voltage vacuum circuit breaker has a series of advantages such as high reliability, large breaking capacity, long maintenance cycle, no pollution, no explosion hazard, and suitable for frequent operation. It has been used in the power industry, Industrial and mining enterprises, railway transportation and other fields have been more and more widely used. [0003] A type of existing high-voltage vacuum circuit breaker adopts a form in which an operating mechanism and an arc extinguishing chamber are arranged in front and rear. The operating mechanism uses an energy-stored spring as a power source to make the circuit breaker operate. Spring energy storage can be divid...
