Embodiment 1

[0047] This embodiment is a fuse capable of withstanding lightning current shocks, such as Figure 1-3 As shown, it mainly includes a cylindrical insulating tube 3 structure, and two openings of the insulating tube 3 are provided with electrode 1 structures for sealing. The electrode 1 is provided with an inwardly recessed protruding part, the protruding part penetrates into the opening of the insulating tube 3, and is bonded to the surface of the ring-shaped flange of the insulating tube 3 and the electrode 1, and in the bonding gap Adhesive insulating glue is provided at the place.

[0048] It can be seen in the figure that when the two symmetrically arranged electrodes 1 are fixed on the opening of the insulating tube 3, there is still a certain distance between the two protruding parts inside, so as to form a gap with the inert gas filled inside the insulating tube 3. discharge gap.

[0049] However, in this embodiment, a structure of a fuse 2 is provided on the outer wa...

Embodiment 2

[0053] This embodiment is a fuse capable of withstanding lightning current impact, which includes a cylindrical insulating tube 3 structure, and two openings of the insulating tube 3 are provided with electrode 1 structures for sealing.

Abstract

The invention discloses a fuse tolerant of lightning current and pulse current. The fuse is connected in series with an SPD to serve as an external overcurrent protection device; and the fuse comprises an insulating tube and a fuse wire arranged on the insulating tube to form an integrated structure with the insulating tube, wherein the fuse wire is connected with electrodes arranged at two ends of the insulating tube to form an access, a closed space filled with inert gas is formed inside the insulating tube through the electrodes at the two ends of the insulating tube, and a discharge gap isformed between the two electrodes in the closed space. According to the invention, the discharge gap filled with the inert gas is combined with a fuse wire structure to form the integrated external protection device which can be combined with the SPD to form a comprehensive surge protection system; and the system is small in size, high in integration degree, good in breaking effect and strong incapacity of preventing the influence of lightning pulse current, and cannot be easily broken by mistake when a lightning current passes through the system.

Description

technical field [0001] The invention belongs to the technical field of electronic components, and in particular relates to a fuse capable of withstanding lightning current pulse current. Background technique [0002] Lightning disasters are one of the most serious natural disasters, causing countless casualties and property losses worldwide every year. With the extensive application of electronic and microelectronic integrated equipment, the damage to systems and equipment caused by lightning overvoltage and lightning electromagnetic pulse is increasing. Therefore, it is very important to solve the lightning disaster protection problems of buildings and electronic information systems as soon as possible. [0003] With the increasingly stringent lightning protection requirements for related equipment, the installation of surge protectors to suppress surges and instantaneous overvoltages on the lines and discharge overcurrents on the lines has become one of the important link...
