The converter transformer valve side outgoing line insulation structure refers to an insulation structure from a sleeve oil end to a valve winding outgoing line end, and comprises a sleeve oil end, a voltage-sharing electrode (used for shielding a connection structure between the end part of the sleeve oil end at high voltage and the end part of a winding lead), a voltage-sharing electrode insulation cover, a multilayer paperboard screen system and insulation of the valve winding lead. The insulation structure is a key insulation part of the converter transformer and bears severe electric field stress, and insulation faults of the high-voltage converter transformer in tests and operation are mostly generated at the position. Besides radial multilayer oil paper insulation is necessary to resist the voltage of the high-voltage electrode to the ground, the high-voltage electrode is prevented from axially flashover along the surface of the sleeve or the lead wire or along the inner wall of the insulating cylinder. The electric field distribution of the insulation structure under alternating-current property voltage (power frequency, lightning impulse and operation impulse voltage) depends on the capacitance coefficient of a medium, and the electric field is mainly concentrated in oil; the electric field distribution under steady-state direct current voltage depends on the resistivity of the medium, and the electric field is mainly concentrated in the paperboard; while the electric field distribution at transient dc voltages (dc boost and polarity reversal) depends on both the capacitance coefficient and the resistivity.
