Problems with the conductivity of the electrolyzer

During the operation of the electrolyzer, if the inlet hose leaks, arcing to ground can occur, damaging the electrolyzer. Saturated salt water is conductive, and the inlet pipe is also made of metal; so why isn’t an electric current generated that could cause a fire? If the outlet pipe does not generate electricity due to a high gas-liquid ratio, then the inlet pipe has no such problem at all. Why is this? Is that the reason? It’s because it’s direct current with a low voltage (3V), and since metals have high resistance, the current generated is small. It is also possible that, during the design of the electrolyzer, this issue was taken into account, and a special design was employed to ensure that no current is generated by the electrolyzer. # ， ， &
Didn’t your import pipelines have grounding devices before? There should be inlet hoses; at the junctions between these hoses and the inlet pipes, non-metallic gaskets are used as isolators. The liquid flows inward, and only a small amount of electricity flows back through the liquid, which can be safely handled by the grounding system.
During the operation of the electrolyzer, a leakage current is still present; it merely varies depending on the degree of rational design of the electrolyzer.
Why are no circuit breakers installed at the inlet and outlet of the alkaline solution and brine in ion-exchange membrane electrolyzers? http://bbs.hcbbs.com/thread-230634-1-3.html There are no circuit breakers installed at the inlets and outlets for the alkaline solution and brine in ion membrane electrolyzers, and this is related to the structure of such electrolyzers: a) The inlet pipes for the alkaline solution and brine in ion membrane electrolyzers are made of relatively long polytetrafluoroethylene hoses, which increases the resistance of the flow of alkaline solution and brine into the electrolyzer. The longer the polytetrafluoroethylene hose, the greater the resistance; when its length exceeds a certain value, it can effectively serve as a circuit breaker ； b. The outlet pipes for the alkaline solution and brackish water in the ion-exchange membrane electrolyzer are made of corrugated polytetrafluoroethylene hoses, which increases the resistance of the alkaline solution and brackish water exiting the electrolyzer. Additionally, the alkaline solution and brackish water coming out of the electrolyzer are in the form of a foamy gas-liquid mixture, and this further increases their resistance. Therefore, no circuit breakers are required at the inlet and outlet of the alkaline solution and brine in ion-exchange membrane electrolyzers.
:) I was wondering if you could explain to me in more detail what the exact purpose of a grounding device is. Thank you :handshake
