Problems solved by technology
In this technical field, the current problem is that while the surge protector is protecting the equipment, its own devices will gradually deteriorate and be damaged or directly damaged under the impact of excessive surges, and the switching devices will generate freewheeling. Both seriously affect the normal operation of the equipment or system, especially the short circuit caused by the damage of the device is more serious. At this time, it should be disconnected from the line in time, otherwise there will be burning, switch tripping, power supply interruption, signal transmission failure and other phenomena.
This method has the following problems: connecting circuit breakers or fuses in series on the surge protector line takes up a lot of space, the connecting lines are numerous and coiled, the inductive reactance of the lines is increased, and the response time is slowed down, and the residual voltage at both ends of the lines increase, resulting in a decrease in the overall surge protection effect

The invention relates to a novel surge protector. The surge protector mainly comprises a base (1), a lightning protection module (2) and a short circuit protection module (3), wherein the short circuit protection module (3) is plugged or pressed on the lightning protection module (2) and connected with the lightning protection module (2) in series. The short circuit protection module (3) is open when the lightning protection module (2) is in short circuit, so the lightning module (2) in short circuit can be released from a line. The whole protective performance of the surge protector is improved due to the reduction in the length and inductance of connecting lines; and the surge protector can be applied in the protection of power lines, signal lines, control lines and the like.
Description
technical field [0001] The invention relates to a novel surge protector, which belongs to the technical field of surge protection for electrical and electronic equipment. technical background [0002] The line surge caused by various reasons such as lightning is an important cause of aging or damage to electrical and electronic equipment. It is an important protection to install surge protectors on metal lines such as power lines, signal lines, and control lines of electrical and electronic equipment. One of the measures. In this technical field, the current problem is that while the surge protector is protecting the equipment, its own devices will gradually deteriorate and be damaged or directly damaged under the impact of excessive surges, and the switching devices will generate freewheeling. Both seriously affect the normal operation of the equipment or system, especially the short circuit caused by the damage of the device is more serious. At this time, it should be dis...
