Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a novel lightning protection and leakage circuit breaker. Background Art

[0002] The new lightning protection leakage circuit breaker is a device used to protect the safety of lines and electrical equipment. It can effectively absorb lightning surges and improve the reliability of the circuit breaker protection function. It is mainly used in civil aviation, railways, industry and mining, scientific research, electricity, finance, meteorology, and families, and plays a good protective role for modern electronic products such as instruments, computers, televisions, and communication equipment.

[0003] However, when the existing lightning protection leakage circuit breaker is in use, screws are usually used to fix the internal circuit parts of the circuit breaker to ensure a firm connection between the circuit breaker and various circuit parts so that they will not loosen or fall off during operation. When the circuit breaker is struck by lightning during use, the lightning will generate a strong electromagnetic field, which may cause electromagnetic induction inside the circuit breaker, generate vibration, and cause the screws to loosen, thereby reducing the connection line between the internal circuit parts of the circuit breaker and the screws, increasing the risk of leakage.
