The working principle is as follows: firstly, in the actual working process, an output line I43 is inserted into the penetrating pipe 31 to be contacted with a copper bar 36, and an output line II 44 penetrates through the mounting frame plate 1 to be contacted with an iron sheet shell of the high-voltage cabinet, so that an electrolytic cell with air in the cabinet as a medium is formed between the iron sheet and the copper bar 36 under the action of an external power supply of the power supply 41, and the copper bar 36 connected with the output line I43 forms an anode under the action of current, so that electrons are continuously lost to form a copper ion state, so that the copper bar 36 is more easily combined with oxygen ions in the air compared with an iron sheet cabinet body, and copper oxide is formed, and further the iron sheet cabinet body has a cathode protection effect, and the anti-corrosion effect on the cabinet body is achieved;
then, after the copper oxide on the surface of the copper bar 36 is gradually increased, at the moment, the motor 8 is started by pulling out the output line I43, and under the action of the meshing gear 7 and the toothed ring 35, the anode binding component 3 is effectively driven to integrally rotate, so that the copper oxide on the surface of the copper bar 36 is fully contacted with carbon powder in the carbon containing groove 37, and the heating coil 6 is electrified at the moment, so that the copper oxide and the carbon powder react in a high-temperature environment to generate simple substance copper and carbon dioxide, the surface of the copper bar 36 is effectively reduced, and the purpose of prolonging the use effect of the copper bar 36 is achieved;
carbon dioxide is generated during the reduction of the copper bar 36, since its relative molecular weight is less than the switching gas SF inside the high-voltage cabinet 6 The relative molecular weight of the sulfur and the sulfur will gradually float to the upper part and escape under certain environment, and the SF inside the cabinet body is easily caused in the process of escaping 6 The loss occurs, resulting in the loss of arc extinguishing gas inside the cabinet, affecting the internal insulation effect, detecting the internal pressure through the pressure sensor 9 at the moment, so as to open the electromagnetic valve 56, and store the SF inside the gas storage tank 55 6 Releasing the air to supplement the air in the cabinet body, thereby ensuring the effective insulation property in the cabinet body;
during the heating process of the heating coil 6, the air pump 54 can be started to supply SF below the cabinet interior 6 Twitch and rise to the top, and from the top blowout of air duct 11, guarantee its equipartition at the internal portion of cabinet, improve the insulating effect of arc extinguishing, and this gas obtains effective intensification processing under heating coil 6's effect at the in-process of 11 inside conductions of air duct, thereby make the temperature of the internal portion of cabinet rise, thereby avoided the in-process that the cabinet body was place at external environment, because outside temperature is higher than inside temperature and leads to the condition emergence that the electric respiration made the internal portion of cabinet into, thereby reached anticorrosive effect to a certain extent.
