Problems solved by technology

[0002] The conventional air gap structure has special nonlinear current-voltage switching characteristics. Once abnormal conditions occur, such as lightning strikes, electromagnetic field interference, frequent power switch actions, power system failures, etc., the voltage on the line will suddenly increase, exceeding the air gap. The breakdown voltage will enter the conduction area, causing the overvoltage to form a surge current to flow out, so as to protect the connected electronic products or expensive components. With the rapid development of self-control electronic technology, components are required to be miniaturized, flattened, and functionalized. Therefore, the conventional single insulating ring gap is easily carbonized due to arc burning, and the edge of the hole is easy to carbonize, which cannot meet the long-term reliable operation and needs further improvement

Description

technical field [0001] The invention relates to the technical field of switch-type surge protection design, in particular to a gap structure with multi-layered large and small hole insulating rings for surge protection. Background technique [0002] The conventional air gap structure has special nonlinear current-voltage switching characteristics. Once abnormal conditions occur, such as lightning strikes, electromagnetic field interference, frequent power switch operations, power system failures, etc., the voltage on the line suddenly increases, exceeding the air gap. The breakdown voltage will enter the conduction area, causing the overvoltage to form a surge current to flow out, so as to protect the connected electronic products or expensive components. With the rapid development of automatic control electronic technology, components are required to be miniaturized, flattened and functionalized. , Therefore, the gap of the conventional single insulating ring is easily carb...
