However, the prior art has the following disadvantages:
1. whether the inert protection device or the micro-positive pressure protection method is adopted, a large amount of inert gas is filled in the pry body, so that a stable gas source is required to be provided for equipment, and certain requirements are placed on the place where the equipment is placed.
2. The micro-positive pressure protection method has certain requirements on the pressure resistance of the pry body, is not suitable for the pry body with holes and holes on the surface, and meanwhile, the detected gas pressure is not the partial pressure of hydrogen or oxygen, but the gauge pressure of the mixed gas in the pry body, so that the positive correlation between the pressure in the pry body, the hydrogen concentration and the oxygen concentration is influenced.
