Embodiment Construction

[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] An embodiment of the measuring device of the present invention, such as Figure 1 to Figure 6 As shown, the measuring device is applied to the measurement of the contact displacement of a circuit breaker with moving contacts. The circuit breaker includes a circuit breaker body 9, and a moving contact assembly is arranged inside the circuit breaker body 9. The moving contact assembly includes upper and lower The moving pull rod 7 and the moving contact (not shown in the figure) connected to the upper end of the pull rod 7 are provided with a lever on the side wall of the circuit breaker body 9, and the lever includes a long connecting plate 1, which is the input arm, and a long connecting plate 1 One end of one end moves synchronously with the pull rod 7 to form the displacement input end, the middle part is hinged on the shell side wall of the cir...

Abstract

The invention relates to a contact displacement measurement method and a measurement device thereof. The measurement device comprises a lever. The lever comprises a displacement input end connected with a contact in a switch to realize synchronous action, and a displacement output end extending out of the switch body. The displacement output end is provided with an output displacement measurementpoint. According to the lever principle, movement stroke of the contact is transferred to the displacement output end outside the switch body, and then the stroke is read by the corresponding measurement means; the device is simple in structure; and by transmitting the inner displacement through the lever structure, displacement measurement can be operated easily.

Description

technical field [0001] The invention relates to a contact displacement measurement method and a measurement device thereof. Background technique [0002] At present, indoor circuit breakers are developing towards miniaturization, and higher and higher requirements are put forward for the performance and size of circuit breakers. During the working process of circuit breakers, it is necessary to ensure that the closing action of the main circuit has good contact, and the opening action can The separation is in place quickly, so it is necessary to measure the movement stroke of the moving contact of the main circuit from time to time, so as to facilitate the subsequent adjustment of the position of the moving contact. The previous measurement method is to directly place the displacement sensor inside the circuit breaker. When the circuit breaker stops working, the opening and closing action of the circuit breaker is controlled to detect the movement stroke of the moving contac...
