Abstract
The utility model relates to a converter transformer case lid shielding structure belongs to converter transformer preparation equipment technical field. Technical scheme is: contain shield plate (1), fastener (2), converter transformer case lid (3) and mounting hole, shield plate (1) is made by aluminum plate, and including horizontal plate (5) and vertical panel (6), horizontal plate (5) and vertical panel (6) constitute integratively, is the L form, is protruding form in the middle of horizontal plate (5), and both sides are equipped with the mounting hole respectively, and fastener (2) are passed the mounting hole and are fixed shield plate (1) on converter transformer case lid (3), make for insulating material fastener (2). The beneficial effects of the utility model are that: converter transformer case lid overheated position through insulating fastener installation aluminium shield plate, reduce eddy current loss effectively, avoid the converter transformer case lid overheated, simple structure, moreover because the aluminum plate quality is little, simple to operate.
Description
Technical field
The utility model relates to a kind of converter transformer case lid shielding construction, belongs to converter transformer making apparatus technical field.
Background technology
Converter transformer is vital key equipment in super high voltage direct current electricity transmission engineering, is the nucleus equipment of the change of current in AC and DC transmission system, inversion two end interface.Its input and safe operation are key and the important guarantees that engineering obtains power benefit.
The case lid of conventional converter transformer is not with shielding, is welded by steel plate bending completely.Have complicated magnetic circuit and circuit because the change of current becomes inner, general converter transformer is furnished with lead-in wire near the part of case lid, forms larger eddy current, causes lid section overheated, affect the performance of converter transformer.
Utility model content
The utility model object is to provide a kind of converter transformer case lid shielding construction, crosses thermal site and installs aluminium barricade by insulated fasteners, effectively reduce eddy current loss, avoid case lid overheated, solve Problems existing in background technology at converter transformer case lid.
The technical solution of the utility model is:
A kind of converter transformer case lid shielding construction, comprise barricade, securing member, converter transformer case lid and installing hole, described barricade is made up of aluminium sheet, comprise level board and vertical panel, level board and vertical panel are integrally formed, in L shape, convex in the middle of level board, both sides are respectively equipped with installing hole, and barricade is fixed on converter transformer case lid by fasteners through mounting holes, and described securing member is that insulating material is made.
Described installing hole comprises installing hole one and installing hole two, and the bilateral symmetry of installing hole one and installing hole two level board convex along centre is arranged.
The beneficial effects of the utility model are: cross thermal site at converter transformer case lid and install aluminium barricade by insulated fasteners, effectively reduce eddy current loss, avoid converter transformer case lid overheated, structure is simple, and due to aluminium sheet quality little, easy for installation.
Accompanying drawing explanation
