Press plate and outgoing line matching structure for transformer and outgoing line method of press plate and outgoing line matching structure

Abstract

The invention relates to a press plate and outgoing line matching structure for a transformer and an outgoing line method of the press plate and outgoing line matching structure. The press plate and outgoing line matching structure is provided with a press plate and an oil sealing plate, wherein the press plate comprises a press plate body and a cushion block, the press plate body and the cushionblock are connected in a sliding way and in a step abutting mode, and the oil sealing plate is arranged at a lower part of the press plate. The method comprises the steps of separating the press platebody from the cushion block in a drawer mode, and allowing the press plate to expose out of an opened groove; installing an outlet each-layer angle ring and an insulation piece at the groove; inserting the cushion block into the groove for installation after the outlet each-layer angle ring and the insulation piece are completed, and fixing the cushion block by a paperboard pin; installing and fixing the oil sealing plate at a corresponding position of the lower part of the press plate by employing an insulation screw rod and a nut, so that the integral structure is completed. An epitaxial part of an hole of the press plate is separated in a drawer mode, the operation space of the outlet installation angle ring and the insulation piece is also ensured on the premise that the installationsize requirement of a design theory is ensured, operation is facilitated, and meanwhile, the cooling efficiency of a strong oil guide structure of a product is ensured.

Description

technical field [0001] The invention relates to a manufacturing technology of a transformer, in particular to a matching structure of a pressure plate and an outgoing line for a transformer and an outgoing line method thereof. Background technique [0002] With the rapid development of UHV transmission projects, the voltage level and transmission capacity of transmission lines continue to increase, and the demand for high-voltage and large-capacity power transformer products is also increasing year by year. The terminal insulation level determines the complex terminal outlet structure of the transformer, that is, the oil-paper partition type outlet method composed of multi-layer corner rings and stays. In the actual assembly operation of the coil set, the conventional pressing plate is a circular plate with outlet holes, which are closed in a circular shape. After the lower pressure plate is installed first, the complex outgoing line structure at the lower end of the transf...
