Heating electrodes of the fully-immersed equipment are completely immersed in conductive medium water, a phase electrode and a zero-position electrode conduct electricity through the medium water in the middle, so that the medium water is heated, a protection shield is arranged between the phase electrode and the zero-position electrode, the conductive area of the medium water is changed through the lifting of the protection shield, so that the heating power is changed, and the outlet temperature of hot water is controlled. The protection shield works in a high-temperature environment of about 100 ℃, and simultaneously bears a high voltage of 10KV, so that the protection shield has high requirements on materials, mainly depends on import at present, and has high cost and long supply period. The protection shield needs to realize the lifting function through mechanical mechanism, and moving parts need to pass through the equipment body, has increased the hidden danger that the equipment body leaked. The semi-immersion type equipment tank is internally provided with an inner container, a heating electrode is inserted into the inner container, the inner container is used as a zero electrode, medium water is filled between the heating electrode and the inner container, the heating power is adjusted by adjusting the water level of the medium water in the inner container and changing the height of the electrode immersed medium water, and the outlet water temperature of hot water is controlled. The semi-immersion type is that a water pump is used for pumping medium water into the inner container, the water level is easy to fluctuate, the immersion parts of the three electrodes are inconsistent, so that three-phase load is unbalanced, and the high-voltage switch cabinet can be tripped during serious operation; meanwhile, the water level fluctuation can also cause load fluctuation, and the quality of the power grid is influenced; the water level adjustment has hysteresis, so that the power adjustment rate is influenced; fluctuating water bloom may also form an arc discharge, affecting safety performance.

Moreover, because a protection shield needs to be arranged in a fully-immersed mode, the distance between a phase electrode and a zero-position electrode is increased more, the conductivity of the medium water needs to be more than 100 mu s/cm, the using amount of inorganic salt is increased, the water quality pollution degree is increased, and meanwhile, the risk of leakage of electricity through the medium water during faults is increased due to the fact that the conductivity of the water rises.
