The invention discloses a lightning protection simplified structure of a passive filter, and belongs to the technical field of lightning arresters. The lightning protection simplified structure comprises a cavity, the cavity is detachably connected with a cover plate, and the left side of the cover plate is provided with an output end lightning protection PCB; the lower side of the output end lightning protection PCB is provided with an output end insulation non-metal gasket, the output end insulation non-metal gasket is fixed between the cover plate and an output end lightning protection PCB interlayer, and the output end lightning protection PCB and the output end insulation non-metal gasket are detachably connected to the cover plate through fifth fixing screws; an output end inductance winding coil is inserted into the output end lightning protection PCB, and an input end lightning protection PCB is arranged at the left side of the cover plate. According to the invention, the defects of high cost, poor universality and inflexible use caused by the limitation of appearance space when filter series products are designed to meet the lightning protection requirement are overcome; and meanwhile, the structure is low in processing cost, is easy for batch implementation, is flexible to adjust and is capable of being completed through multi-path coordination.
Description
technical field [0001] The invention relates to the technical field of lightning arresters, in particular to a simplified lightning protection structure of a passive filter. Background technique [0002] Surge arrester is an electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes, and to limit the freewheeling time and often limit the freewheeling amplitude. Lightning arresters are sometimes called overvoltage protectors and overvoltage limiters. In the field of wireless communication, filters, duplexers, multiplexers and other products often have lightning protection requirements designed to protect the product itself from being struck by lightning. The harm of the state voltage and current makes the product smooth and unusable, so the requirements for lightning protection are added under the premise of meeting the indicators of filters, duplexers, multiplexers and other products; [0003] At present, most ...
