Edge shielding structure of electric reactor magnetic shielding plate

Abstract

The invention relates to an edge shielding structure of an electric reactor magnetic shielding plate and belongs to the technical field of electric reactors. According to the technical scheme, the edge shielding structure comprises a lamination wood wire clamp (5), aluminum foil crepe paper (6), a copper braided wire (7) and crepe paper (8), wherein one side of the lamination wood wire clamp is provided with a fillet (9) which is wrapped by the aluminum foil crepe paper, the copper braided wire is disposed on the inner side of the aluminum foil crepe paper which is wrapped by the crepe paper, and an exposed head of the copper braided wire is connected in a pressing manner through a pressing connector (4) to form edge shielding (3). The edge shielding is mounted on the magnetic shielding plate (2) through glass fiber screw. One side of the fillet faces outwards. The pressing connector is fixed on a metal component of the magnetic shielding plate through a stainless steel fastener so as to improve the electric field environment at a corner of the magnetic shielding plate. The edge shielding structure has that advantages that electrode shapes, in an electric field, of the electric reactor magnetic shielding plate corner is improved, and the risk of potential partial discharge is lowered.

Description

technical field [0001] The invention relates to an edge corrugated shielding structure of a magnetic shielding plate of a reactor, and belongs to the technical field of reactors. Background technique [0002] At present, with the technological progress of shunt reactors, the volume of the reactor is getting smaller and smaller, which makes the internal space of the reactor body become very compact, and the insulation distance between the coil and the structural member is also becoming smaller. The reduction of the insulation distance makes some iron core structures with poor electrode shapes in a high electric field intensity, which is easy to cause partial discharge, damage the reactor, and endanger the safety of power grid operation. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an edge corrugated shielding structure of the magnetic shielding plate of the reactor, improve the electric field environment at the magnetic shielding plat...
