| description | The invention discloses an epoxy resin pouring method of a mutual inductor. The pouring method comprises the following steps of heating a mold, a pouring tank and a gas cylinder for storing SF6 to a first preset temperature, a second preset temperature and a third preset temperature; exhausting gas in the pouring tank to enable the vacuum degree of the pouring tank to be lower than 50 Pa, and obtain the gas-exhausted pouring tank; filling the gas-exhausted pouring tank with SF6 gas in the gas cylinder to enable the vacuum degree of the pouring tank to be 0.039 to 0.04 MPa and obtain the gas-filled pouring tank; and pouring the epoxy resin in a final mixing tank into the mold in the gas-filled pouring tank according to a preset flow diameter. According to the method, a certain amount of SF6gas is injected in the vacuum pouring process, so that the SF6 gas can enter the interlayers of a primary winding of the voltage transformer, epoxy resin cannot permeate into the gap, and the initialdischarge voltage of the |
