Description

Technical Field

[0001] The invention relates to a surge protector, and in particular to a surge protector protection method for protecting the surge protector. Background Art

[0002] Surge protector Surge protector, also called lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other equipment in the circuit; surge protectors are usually suitable for use in AC 50 / 60HZ, rated voltage 220V / 380V power supply systems to protect against indirect lightning and direct lightning effects or other transient overvoltage surges. They are widely used in residential, tertiary industry, industrial and other application scenarios with surge protection needs. Existing surge protectors do not have a backup switch voltage limiting protection function, which can easily cause damage to the protected lines or products due to lack of protection during the safety protection process.

[0003] The authorized patent number ZL202220940751.1, which was announced on October 21, 2022, discloses a surge protector for lightning protection engineering, including a slide rail body, the surface of the slide rail body is longitudinally slidably connected to the surge protector body, the interior of the slide rail body is transversely slidably connected to a moving rod through a limit groove and a limit rod, and the top and bottom of the moving rod are both provided with movable grooves, and the interior of the movable groove is movably connected to a connecting rod through a pin shaft. The utility model solves the problem that the stability of the existing surge protector needs to be improved by setting the slide rail body, the surge protector body, the moving rod, the movable groove, the connecting rod, the plug rod, the round block, the support plate, the spring, the clamping groove, the fixing plate, the outlet and the push rod. When the surge protector is used, it is generally slidably limited on the surface of the slide rail for fixed use. The slide rail can only limit the surge protector, and cannot effectively ensure that the surge protector is stably placed on the surface of the slide rail, which reduces the problem of the stability of the surge protector. This solution also has the problem of not having a backup switch voltage-limiting protection function, which may cause damage to the protected lines or products due to lack of protection during the safety protection process. Summary of the invention

[0004] The present invention aims to solve the problem that the existing surge protector has no backup switch voltage limiting protection function, which easily leads to damage to the protected lines or products due to lack of protection during the safety protection process. The present invention provides a multifunctional combined backup surge protector protection method that can provide multifunctional combined backup surge protection for electronic equipment, instruments and meters, and communication lines, thereby improving the safety protection of use to a greater extent and more effectively avoiding damage to the protected lines or products.

When the lightning surge energy reaches a certain level, the gas discharge tube FDG is first instantaneously started and turned on to the B connection point. As the lightning surge increases again, the single-stage gap JX component is started and turned on to the B connection point. When the T2 voltage-limiting varistor MOV component in the right surge protector zone detects that the B connection point is in the state of high voltage and high current of the lightning surge, the T2 voltage-limiting varistor MOV component is instantaneously started to maintain the voltage-limiting linear discharge of the lightning surge to the ground terminal.
