Multi-cavity modular self-assembly structure and processing method

Abstract

The invention discloses a multi-cavity modular self-assembly structure and a processing method. The multi-cavity modular self-assembly structure comprises a grounding module, a high-voltage end module and a plurality of middle modules, wherein the plurality of middle modules are located between the grounding module and the high-voltage end module, the plurality of middle modules are detachably connected in a joggle joint mode, and the middle modules, the grounding module and the high-voltage end module are detachably connected in a joggle joint mode. The multi-cavity modular self-assembly structure is in contact with an air gap through the grounding module and is connected with a lower arc guide arm through the high-voltage module. Due to the fact that the free assembly type modular structure is adopted, the number of arc extinguishing chambers can be combined at will, and the structure used for a middle-low voltage level circuit is obtained. Compared with an existing integrated multi-cavity arc extinguishing structure, the multi-cavity modular self-assembly structure is low in error rate in the machining process, it can be guaranteed that the structural strength is still stable, and impact arcs can be rapidly extinguished.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a multi-chamber modular self-assembly structure and a processing method. Background technique [0002] With the development of social economy, people's demand for electricity is increasing, and the requirements for technical and economic indicators of power grid operation at various voltage levels are increasing. Accidents such as tripping caused by lightning strikes and flashover of insulators seriously threaten the safe operation of power transmission and distribution lines. The multi-chamber arc extinguishing structure is used in lightning protection due to its excellent arc extinguishing performance. [0003] In recent years, scholars at home and abroad have developed a new type of lightning protection device based on a multi-chamber structure. However, this type of device is often integrated and belongs to consumables: it is impossible to obtain a structure suitabl...

AI Technical Summary

Problems solved by technology

However, this type of device is often integrated and belongs to consumables: it is impossible to obtain a structure suitable for lines of various voltage levels through mortise joints of different numbers of intermediate modules, and the on-site installation is cumbersome; The surface of the electrode is strongly burned and cannot be used for a long time. Therefore, the device at the current stage needs to be replaced every once in a while, requiring a lot of money

In addition, due to the integration of the entire device, the structural strength of the device becomes fragile and easy to break at a very high length, and cannot withstand large external forces; and the processing is inconvenient, and the interruption rate and error rate are high during the processing
