[0033] Embodiment 1﹒

[0034] figure 1 It is a cross-sectional view showing a schematic configuration of an ozone generator according to Embodiment 1 of the present invention. figure 1 Among them, inside the ozone generator main body container 12, a cylindrical dielectric tube 1 and a ground metal electrode 11 are paired to form a single discharge tube. figure 1In order to describe the discharge tubes in detail, only two discharge tubes are shown, but in a large-capacity ozone generator, several hundreds of discharge tubes are provided inside one ozone generator main body container 12 . For example, the dielectric tube 1 is formed of a cylindrical glass tube, and the ground metal electrode 11 is formed of a pipe made of stainless steel. A narrow discharge gap 25 is formed between it and the ground metal electrode 11 . One end (right end) of the dielectric tube 1 is closed, and the other end (left end) is opened. A voltage applying electrode 2 is provided inside the diel...

Abstract

An ozone generation device provided with a plurality of discharge tubes, each having a discharge gap between a voltage application electrode and a ground metal electrode with a dielectric disposed therebetween, wherein an oxygen-containing gas flows in each discharge gap, and an alternating-current voltage from an alternating-current power supply is applied across the voltage application electrodes and the ground metal electrodes in order to cause the oxygen-containing gas to be discharged to become ozonized gas. Midway along the path of the electrical feed from the alternating-current power supply to the voltage application electrodes of the plurality of discharge tubes, there is connected a current blocking element comprising: a fusing element in which fuse conductors that melt due to the flow of an over-current are disposed on both sides of an intermediate conductor; and plate-shaped fixed electrodes connected to both sides of the fusing element, each of the fixed electrodes havinga plate surface fixed to a surface of a base of the dielectric by means of a fixing material.

Description

technical field [0001] The present invention relates to an ozone generator that ozonates an oxygen-containing gas by electric discharge, and particularly relates to a current cutoff element provided for operation protection. Background technique [0002] In a large-capacity ozone generator, more than 100 discharge tubes are used as loads connected to a power source. In such an ozone generator, according to the variation of the discharge tubes, a device is proposed in which each discharge tube is provided with a fuse so that even if a short-circuit discharge occurs in one discharge tube, an arc discharge is generated from the discharge tube. In the case of , only the discharge tube can be disconnected from the power supply, and the operation of the entire device can be continued (for example, refer to Patent Document 1). [0003] During the operation of the device, the insulation of the dielectric tube constituting a certain discharge tube is damaged, resulting in the openin...
