Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker installation, in particular to a novel complete set of pole-mounted circuit breaker. Background Art

[0002] The vacuum circuit breaker is named because its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum. It has the advantages of small size, light weight, suitable for frequent operation, and arc extinguishing without maintenance. It is widely used in distribution networks. The vacuum circuit breaker mainly consists of three parts: vacuum arc extinguishing chamber (commonly known as vacuum arc extinguishing chamber), electromagnetic or spring operating mechanism, bracket and other components. Among them, the vacuum arc extinguishing chamber is one of the most important components. Its main function is to connect or disconnect the power supply under the rental of the electromagnetic or spring operating mechanism. Since vacuum is a good insulator, it can extinguish the arc when disconnected. Therefore, the vacuum performance of the vacuum arc extinguishing chamber is directly related to the regulation of vacuum. The pole-mounted circuit breaker is a type of vacuum circuit breaker, which refers to a circuit breaker installed and operated on a pole. Its structure also has a vacuum arc extinguishing chamber. The arc is extinguished through the internal vacuum environment. It is quite necessary whether the vacuum environment of the vacuum arc extinguishing chamber is destroyed. A Chinese patent discloses a new type of complete pole-mounted circuit breaker (authorization announcement number CN219677135U). The patent technology discloses a new type of complete pole-mounted circuit breaker, including a vacuum arc chamber, a through hole is opened in the middle of the vacuum arc chamber, and a maintenance pipe is fixedly connected to the through hole. The maintenance pipe can be vacuum-tested by a detection device. The detection device includes an optical recognition camera, a vacuum pump is provided on the side of the optical recognition camera, and a camera barrel is provided at the front end of the optical recognition camera. The camera barrel is detachably connected to the maintenance pipe, which is used to solve the problem that the current detection device needs to disassemble the vacuum arc chamber before detection. However, in actual work, it is necessary to perform vacuum detection on the installed complete pole-mounted circuit breaker vacuum arc chamber, and this equipment cannot meet the on-site detection needs. This patented technology solves the existing technology. Although the vacuum arc chamber can be accurately tested to determine whether the internal vacuum environment meets the specifications, the use scope of this experimental platform is limited. The vacuum arc chamber needs to be disassembled for testing. In actual work, after the complete set of pole-mounted circuit breakers are installed on the electric pole, the vacuum arc chamber of the installed complete set of pole-mounted circuit breakers needs to be tested for vacuum. This equipment cannot meet the needs of on-site testing.

[0003] However, in the prior art, after the complete set of pole-mounted circuit breakers are installed on the pole, the distance between them and the pole is fixed. When the pole is relatively wet, arcing is easily generated. It is necessary to solve the problem in the prior art that the complete set of pole-mounted circuit breakers can be installed on the pole and the distance between them can be adjusted.

[0004] Therefore, those skilled in the art provide a new type of complete pole-mounted circuit breaker to solve the problems raised in the above background technology. Utility Model Content
