In order to protect the whole safety of the power supply and the equipment, a safety device needs to be connected in series to each discharge chamber, and once overload condition occurs, the power supply of each discharge chamber is immediately fused and cut off. Because the plate-type ozone generator works under the high-frequency and high-voltage state, the high-potential circuit must be completely enclosed inside the voltage-resistant insulating material for personal safety and equipment safety, and all possible phenomena of arc discharge caused by continuous borrowing are completely eradicated in the circuit, so that catastrophic results are caused to the equipment. The moist air is immersed in the air, so that the welding spots and the low potential part near the outside can be caused to form creepage, breakdown or electric leakage, and the equipment is burnt.
The traditional series connection of the fuse tube and the circuit adopts a soldering process, and the welding point is required to be sealed and packaged. Once the fuse tube is fused, the production site cannot be replaced and maintained, and the whole equipment can only be sent back to a manufacturer for maintenance and replacement, so that the maintenance workload is large, the cost is high, the period is long, and the production is greatly influenced. Therefore, how to realize the on-site quick replacement of the discharge chamber and the protective tube becomes a problem to be solved.
