Description

Technical Field

[0001] The utility model relates to the field of arc experiments in high-voltage switch cabinets, in particular to an arc experiment device inside a switch cabinet. Background Art

[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switch cabinets, with high-voltage busbars, such as power plants, etc. Some also have low-frequency load reducers to protect the main equipment.

[0003] The main function of the switchgear is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protective devices. Switchgear above AC1000V is called high-voltage switchgear.

[0004] During the use of the switch cabinet, the contacts in the arc extinguishing chamber of the high-voltage circuit breaker will generate arcs during the breaking process. The arc generation process is accompanied by changes in parameters such as arc temperature and arc shape. Studying the changes in these parameters has very important guiding significance for optimizing the design of high-voltage circuit breakers. Arc tests are generally carried out using arc test devices, but the indicators of some existing arc test devices are inconvenient to install and the position of the indicators cannot be flexibly adjusted, resulting in an increased risk of arc tests. For this reason, we propose an internal arc test device for the switch cabinet. Utility Model Content
