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
The present invention relates to a kind of stupefied shielding construction in limit of reactor flux shield plate, belong to the reactor technical field.
Background technology
At present, along with the technological progress of shunt reactor, the volume of reactor is more and more less, so that device body inner space becomes very compact, coil is also diminishing to the insulation distance of structural member.The reducing of insulation distance very easily caused partial discharge so that the relatively poor core construction spare of partial electrode shape is in the high electric field strength, damages reactor, jeopardizes safe operation of electric network.
Summary of the invention
The stupefied shielding construction in limit that the purpose of this invention is to provide a kind of reactor flux shield plate improves shunt reactor magnetic shield panel place electric field environment, solves the problems referred to above that background technology exists.
Technical scheme of the present invention is:
The stupefied shielding construction in the limit of reactor flux shield plate, comprise lamination wood wire clamp, aluminium foil crimped paper, copper litz wire and crimped paper, one side rounding of lamination wood wire clamp, outer aluminium foil crimped paper, at copper litz wire of the inboard placement of aluminium foil crimped paper, aluminium foil crimped paper external application crimped paper parcel, copper litz wire expose head pressure joint crimping, the formation stupefied shielding in limit; The stupefied shielding in limit is installed on the magnetic shield panel with the glass fibre screw rod, and a side of lamination wood wire clamp rounding is fixed on pressure joint on the hardware of magnetic shield panel by stainless steel support outwardly, improves the electric field environment of magnetic shield panel sharp corner.
The stupefied shielding in limit is installed in reactor flux shield plate sharp corner; Lamination wood wire clamp is also referred to as the lamination wooden frame, and the size of its thickness and length and magnetic shield panel is complementary.
Have circular hole on the lamination wood wire clamp, be fixed on the magnetic shield panel two ends with the glass fibre screw rod, the wooden wire clamp of lamination that exceeds the magnetic shield panel scope is rounding not, also aluminium foil crimped paper not.
Good effect of the present invention is: improved the electrode shape of shunt reactor magnetic shield panel wedge angle in electric field, reduced potential partial discharge risk.
