The invention discloses a multi-line rotary lightning protection device comprising a lightning protection device housing. A low-voltage side circuit board assembly and a high-voltage side circuit board assembly are vertically arranged in the lightning protection device housing. The left end of the lightning protection device housing is provided with a transmission gear, the middle part of the right end of the transmission gear is connected to a rotary connector shaft which extends into a position between the low-voltage side circuit board assembly and the high-voltage side circuit board in thelightning protection device housing, the rotary connector shaft is sealed by rotating a rotary connector shaft end cover and the lightning protection device housing, the upper part of the left end ofthe lightning protection device housing is provided with a star speed reducing motor component, and the star speed reducing motor component is in gear meshing transmission with a driving gear. According to the multi-line rotary lightning protection device, a rotating connection mode is used, and the contact is more firm and closer compared with a compression contact mode. Transformer oil is usedas an insulating oil body, the design volume of the product is reduced, and voltage withstanding level is improved.
Description
technical field [0001] The invention relates to the technical field of lightning protection devices, in particular to a multi-line rotary lightning protection device. Background technique [0002] A large number of integrated components, when a lightning strike occurs, the transmission line induces the lightning electromagnetic field to generate an overvoltage, which can be as high as tens of kilovolts, which has great harm to the integrated components. In the field of rock and soil safety monitoring, people often adopt isolation lightning protection device for protection. Among them, the extruded contact method of the lightning protection device connector is poor in contact tightness, which is prone to poor contact, and the air medium used as the insulator (1000V per 1 mm) has a poor withstand voltage level. To this end, we introduce a multi-line rotary lightning protection device. Contents of the invention [0003] The purpose of the present invention is to provide a m...
