In order to prevent lightning current from being introduced into the equipment through the transmission line, a surge protector having a pressure-sensitive valve sheet is generally installed between the transmission line and the electric equipment.

The current Surge Protector (SPD) has the problems that; after the surge protector is impacted by overvoltage for multiple times, the characteristic is gradually degraded; when the voltage-sensitive chip works normally, the leakage current is continuously increased, so that the voltage-sensitive chip generates heat, thermal breakdown occurs, a power supply short circuit is caused, and a surge protector is burnt out to cause power supply accidents. The conventional mode is to serially connect insurance to the pressure-sensitive chip; however, if the series fuse has a small series fuse capacity, it cannot bear a large overvoltage impact, and when the series fuse has a large series fuse capacity, the fuse may be blown or broken by a large current after the characteristics of the voltage sensitive chip are degraded, which also causes a power supply short circuit and a power supply accident. Meanwhile, the pressure-sensitive valve plate chip has the problem of hot melt breakdown, once the pressure-sensitive valve plate chip is subjected to hot melt breakdown, the pressure-sensitive valve plate chip is equivalent to a conductor with a very low resistance value, a system short circuit is caused, only a breakdown point continues to generate heat, sometimes electric arc combustion occurs, substances in the surge protector are subjected to sudden increase of high-temperature gasification pressure in a very short time, explosion or flaming combustion is caused, and serious consequences of damage to equipment and buildings are caused.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

The utility model relates to a surge protector device with a novel structure, as shown in fig. 1 and fig. 2, comprising a bracket 10, a pressure-sensitive valve sheet 20 and a tripping elastic sheet 30, wherein the pressure-sensitive valve sheet 20 comprises a first electrode 21 and a second electrode 22; the first electrode 21 is connected with a first pin 41 through a tripping elastic sheet 30, the first pin 41 is connected with an external circuit phase line, the second electrode 22 is connected with a second pin 42, and the second pin 42 is connected with an external circuit zero line; in order to solve the problem that the pressure-sensitive valve sheet 20 can be successfully separated from the tripping elastic sheet 30 after early failure (degradation) and is successfully tripped, a protrusion 211 is arranged at the joint of the first electrode 21 and the tripping elastic sheet 30, a connecting hole 31 is formed in the position of the tripping elastic sheet 30 corresponding to the protrusion 211, and the first electrode 21 and the tripping elastic sheet 30 are welded together with the connecting hole 31 through the protrusion 211. Set up like this, can be safer convenient, easy operation when the welding, and the pressure-sensitive valve block is fixed firm, and the welding part is less than the required material of prior art.

As a further optimization and improvement, in order to better enable the pressure-sensitive valve plate 20 and the tripping elastic piece 30 to be smoothly tripped under overvoltage impact generated by factors such as lightning, a joint of the pressure-sensitive valve plate 20 and the tripping elastic piece 30 is welded by using a low-melting-point alloy material, and the alloy material with a melting point of 80-180 ℃ is generally used. Thus, the pressure-sensitive valve plate 20 generates heat under the action of power frequency current under the action of overvoltage impact generated by factors such as lightning, the first electrode 21 conducts the heat to the low-melting-point alloy material through the electrode, so that the low-melting-point alloy material is slightly soluble, and the pressure-sensitive valve plate 20 and the tripping elastic sheet 30 can be smoothly tripped.

Example 2

As a further optimization and improvement, in embodiment 1, the pressure-sensitive valve plate 20 and the trip elastic piece 30 are welded by a low-melting-point alloy material, and in order to further, conveniently and effectively trip the pressure-sensitive valve plate 20 and the trip elastic piece 30, the trip elastic piece 30 is bent, so that when the low-melting-point alloy material is slightly soluble, the elastic force generated by bending the trip elastic piece 30 can separate the pressure-sensitive valve plate 20 from the trip elastic piece 30, so that the failed pressure-sensitive valve plate is separated from the circuit, and the SPD power circuit is cut off.

As a further optimization and improvement, under the condition that the tripping elastic sheet 30 is bent, the insertion part of the protrusion 211 and the connection hole 31 can be welded to achieve a good fixing effect, so that the bending degree of the tripping elastic sheet 30 is convenient to set, and the elastic force required by the pressure-sensitive valve sheet when the pressure-sensitive valve sheet is tripped is convenient to better master. Therefore, in order to ensure that the fixing effect of the insertion part of the protrusion 211 and the connecting hole 31 is better, the number of the protrusions 211 is multiple, the shape is a tooth shape, and the number of the connecting holes 31 is matched with that of the protrusions 211. By the arrangement, welding points of the protrusions 211 and the connecting holes 31 are increased, and the low-melting-point alloy material is better in stability when not slightly soluble.
