Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of circuit breaker test equipment, and in particular relates to a circuit breaker mechanical life test box. Background Art
[0002] When conducting a mechanical life test on a high-voltage circuit breaker, it needs to be controlled by the circuit breaker mechanical life test console to achieve switching operations. Several test cables need to be connected between the high-voltage circuit breaker and the circuit breaker mechanical life test console. Mechanical characteristic measurements of the circuit breaker are required before the start of the high-voltage circuit breaker mechanical life test and after each cycle. Typically, the connection cable between the high-voltage circuit breaker and the circuit breaker mechanical life test console needs to be disconnected, and the test cable between the high-voltage circuit breaker and the circuit breaker mechanical characteristic test bench needs to be connected. After the characteristic test is completed, the test cable needs to be disconnected and then the control cable between the circuit breaker mechanical characteristic test bench needs to be connected. Therefore, during the mechanical life test of the high-voltage circuit breaker, the test cable needs to be disconnected and reconnected multiple times, making the entire process very time-consuming.
[0003] The existing technology generally places the high-voltage circuit breaker in an open area. When conducting a mechanical life test, the high-voltage circuit breaker is connected to the circuit breaker mechanical life test console. When conducting mechanical characteristic measurements, the high-voltage circuit breaker is connected to the circuit breaker mechanical characteristic test bench. The entire test process requires test personnel to patrol the site for monitoring. The circuit breaker mechanical life test lasts for a long time, requiring test personnel to patrol the site, which is a heavy workload. The circuit breaker mechanical life test generates a lot of noise, which is harmful to the health of the test personnel. Electrical fires may occur during the circuit breaker mechanical life test, which will affect surrounding equipment. The circuit breaker mechanical life test needs to be carried out at a certain ambient temperature, but the existing method is basically carried out in a large space, and the temperature regulation efficiency is low. The circuit breaker mechanical life test requires several switches to connect the circuit breaker mechanical life test console and the circuit breaker mechanical characteristic test bench, which is inefficient.
[0004] Chinese patent application CN210090001U, titled "A Thermal Circuit Breaker Mechanical Life Test Device," discloses a thermal circuit breaker mechanical life test device. The device comprises a workbench with a pair of support blocks, a guide rail disposed between the two support blocks, and a sliding block slidably connected to the guide rail. The slide is also hinged to one end of a transmission rod, which is eccentrically hinged to a transmission disc at its other end, which is connected to a drive motor. However, during the testing process, this patent application still presents issues such as the need for on-site inspections by test personnel, the generation of excessive noise, and the risk of fire.
