Embodiment Construction

[0036] Below, introduce the specific embodiment of the utility model in conjunction with accompanying drawing.

[0037] As shown in the figure, the high-power metal-ceramic gas discharge tube for overvoltage protection of the power supply system of the present invention includes an outer electrode 1, an inner electrode 2 and a metallized ceramic ring 3. The outer electrode 1 is a cylinder with an opening at one end and a bottom at the other end. The inner electrode includes a hollow body 23, and the hollow body 23 extends into the barrel of the outer electrode 1, and a metallized ceramic ring 3 is installed between the mouth of the outer electrode 1 and the mouth of the inner electrode 2 extending into the outer electrode 1. Carry out airtight sealing, form airtight gas discharge gap 4 and be filled with inert gas therebetween; There is a central air hole 24 in the center of the top wall of the described hollow body 23 that can accommodate gas, in the described hollow body The...

Abstract

A high power metal ceramic gas discharge tube for power system overvoltage protection relates to a gas discharge tube which is used for avoiding the overvoltage caused by lightning protection and electromagnetic pulse prevention in electronic equipment and power system and avoiding the damage of the electronic equipment caused by overvoltage operation. The gas discharge tube comprises an outer electrode, an inner electrode and a metalized ceramic ring, wherein the inner electrode contains a cavity which extends in the cylinder of the outer electrode, the metalized ceramic ring is arranged between the cylinder opening of the outer electrode and the cylinder opening, extending in the outer electrode, of the inner electrode, the tightness sealing is performed to form a sealed gas discharge gap which is filled with inert gas; the central position of top wall of the cavity which is capable of holding gas is provided with a center air hole, the bottom of the cavity is provided with a plurality of gas inlets, and the center air hole and the gas inlets are used to form a gas circulation path between the discharging gap and the cavity. The effects of the invention are as follows: the alternating current power supply system can be automatically closed when the voltage crosses zero after the overvoltage is clustered, the volume of the gas discharge tube is small while the power is large, the performance is excellent and the production cost is low.

Description

technical field [0001] The invention relates to a discharge tube used in electronic equipment and power supply systems to prevent damage to electronic equipment caused by lightning strikes, electromagnetic pulse overvoltages, and operating overvoltages. Metal-ceramic gas discharge tube with self-closing, small size and large flow capacity. Background technique [0002] Metal-ceramic gas discharge tubes are widely used in electronic equipment and power supply systems to prevent damage caused by lightning strikes, electromagnetic pulses, and operating overvoltages to electronic equipment. It can be said that the problem of whether the AC power system can be shut down reliably when the voltage of the AC power supply system crosses zero after the overvoltage, the size of the volume and the size of the flow capacity are the three major indicators to measure the performance and technological advancement of the metal-ceramic gas discharge tube, all of which are advanced Metal-cera...
