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 residual power at both ends of the line is increased. The voltage rises, resulting in a decrease in the overall surge protection effect

The invention relates to a novel surge protector which mainly comprises a base (1) and a lightning protection module (2), wherein the lightning protection module (2) is internally provided with a relay (3), the relay (3) is connected with a surge suppressor (4) in series, and the relay (3) and the surge suppressor (4) are integrated into a whole by an electrical connection part (5); and when the surge suppressor (4) is short-circuited, the relay (3) can be disconnected so as to disengage the short-circuited surge suppressor (4) from a circuit. By reducing the length and the inductive reactance of a connection circuit, the invention improves the overall protection performance. The novel surge protector can be used for protecting various circuits for power, signals, control and other purposes.
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...
