Embodiment Construction

[0014] The embodiment of arc test device among the present invention is for example figure 1 shown. The arc test device includes a closed chamber 1, and the closed chamber 1 is provided with a static arc contact 4, a moving arc contact 5 and a nozzle 2 that moves with the moving arc contact 5, a static arc contact 4 and a moving arc contact. 5 are arranged up and down relative to each other in the closed chamber 1. The spout 2 is a transparent spout, and when the static and dynamic arc contacts are in the opening state, the end of the static arc contact 4 is located in the spout 2 . The size and shape of the nozzle 2 can be designed and manufactured completely according to the size and shape of the real nozzle in the actual circuit breaker, so the arc test research using the arc test device is closer to the real situation, and the test results will be more accurate. The spout 2 is made of plexiglass, which can withstand the high temperature and high pressure generated when t...

Abstract

The invention relates to an arc test device. The arc test device includes a closed chamber, the closed chamber is internally provided with a static arc contact, a moving arc contact and a nozzle moving together with the moving arc contact, the nozzle is a transparent nozzle, and a first transparent observation window used for observation an arc generated between the static arc contact and the moving arc contact is arranged in a position corresponding to the static arc contact and the moving arc contact on a housing of the closed chamber. The transparent nozzle does not shelter the arc, and does not influence observation of the shape of the arc, and a complete arc shape can be observed through the first transparent observation window.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switch test devices, and in particular relates to an arc test device. Background technique [0002] The contacts in the arc extinguishing chamber of the high-voltage circuit breaker will generate an arc during the breaking process, and the arc temperature and arc shape will change during the arc generation process. It is very important to study the changes of these parameters to optimize the design of the high-voltage circuit breaker. guiding significance. [0003] At present, the traditional arc test device is to place dynamic and static contacts and nozzles in a closed pressure vessel (equivalent to a closed chamber), and perform an arc test in the pressure vessel. However, the nozzles of conventional arc test devices are usually cast epoxy. Because in the actual circuit breaker, when the static and dynamic arc contacts are in the opening state, the nozzle will surround the end of the sta...
