Referring to fig. 1, the present embodiment provides a high-voltage inlet box structure, in the present embodiment, a box body 1 is a casing with a rectangular cross section, and in another embodiment, the cross section of the box body 1 may be circular, oval, or polygonal. One end of the gas inlet pipeline 4 is communicated with the box body 1, and the other end is communicated with an inert gas source, wherein the inert gas source is an inert gas pipeline, and in another embodiment, the gas inlet pipeline can be an inert gas bottle or an inert gas generator and the like. The gas inlet pipe 4 is provided with a gas switch valve 6, in this embodiment, the gas switch valve 6 is an electric valve, and the gas switch valve 6 can control the inert gas to enter the box body 1 from the gas inlet pipe 4. When the gas switch valve 6 is opened, inert gas enters the gas inlet pipeline 4 from an inert gas source, the pressure of the inert gas source is greater than the gas pressure in the box body 1, and the inert gas enters the box body 1 through the gas switch valve 6, so that oxygen and other gases in the box body 1 are discharged, and a fuel medium is prevented from entering the box body, so that the fuel medium cannot be mixed with the oxygen. The inert gas is stable in property, and the explosion risk of the fuel medium caused by mixing with oxygen is eliminated. After the oxygen in the box body 1 is discharged, the cable joint in the box body 1 is prevented from being oxidized, the conductivity of the cable joint is improved, and the service life of the cable joint is prolonged.
In one embodiment, as shown in fig. 1, a gas pressure regulating valve 5 is further provided in the intake duct 4, and the gas pressure regulating valve 5 is provided between the gas switching valve 6 and the case 1. In the present embodiment, the gas pressure regulating valve 5 is an electrically operated valve. The pressure of the inert gas entering the box body 1 is adjusted according to the condition and the requirement by the gas pressure adjusting valve 5, the gas pressure in the box body 1 can be adjusted to be low when the gas pressure is overlarge, and the gas pressure in the box body 1 can be adjusted to be high when the gas pressure is insufficient, so that the situation that the pressure in the box body 1 is too high or too low is avoided.

Gas such as inert gas in the case 1 can be discharged through the purge passage 2, and the purge valve 3 controls the discharge of the gas. When the purge valve 3 is in the open state, gas is discharged from the tank 1. When the purge valve 3 is in the closed state, gas cannot be discharged from the tank 1. When the equipment is overhauled, the inside of the wire inlet box is dead angle, and the inside of the wire inlet box cannot be cleaned and replaced by gas. After setting up diffuse passageway 2 and diffuse valve 3, diffuse the replacement through this diffuse passageway 2 and diffuse valve 3 before overhauing or equipment put into operation, solve the problem that the incoming line incasement is the unable replacement in dead angle.
In one embodiment, an electric heater is arranged in the box body 1, and the electric heater heats the interior of the box body 1, so that the insulation of the wire inlet box is prevented from being influenced by excessive humidity in the wire inlet box.
