Abstract
The utility model relates to a dry-type discharge coil which comprises iron cores, a primary coil, a secondary coil, a primary terminal, a secondary terminal and an epoxide resin insulator, wherein the primary coil and the secondary coil are wound on the iron cores; the primary coil is connected with the primary terminal; the secondary coil is connected with the secondary terminal; the iron cores, the primary coil and the secondary coil are arranged in the epoxide resin insulator by vacuum casting; and a pollution-flashover-proof coating layer is attached on the surface of the epoxide resin insulator. According to the dry-type discharge coil provided by the utility model, by coating pollution-flashover-proof paint on the surface of the dry-type discharge coil, the surface resistance of the discharge coil is increased, and the possibility of pollution flashover failure of the surface of the discharge coil is reduced.
Description
Technical field
The utility model relates to a kind of discharge coil, relates in particular to a kind of dry type discharge coil.
Background technology
Existing dry type discharge coil all adopts the poured with epoxy resin technology to process, because the surface resistivity of epoxy resin is lower, it is creepage to need the area of high pollution flashover grade to be prone to that pollution flashover takes place in high height above sea level, high pollution etc.
Summary of the invention
The purpose of the utility model is to provide a kind of dry type discharge coil, has solved the technical problem that is prone to pollution flashover in the background technology.
The technical scheme of the utility model is:
A kind of dry type discharge coil comprises iron core, primary winding, secondary coil, terminal, secondary terminal and an epoxyresin insulator,
Described primary winding and secondary coil are wound on the iron core;
Described primary winding is connected with a terminal;
Described secondary coil is connected with the secondary terminal;
Described iron core, primary winding and secondary coil vacuum pouring are in epoxyresin insulator;
Its special character is that the epoxyresin insulator surface is with antifouling flash coating layer.
The utility model improvement further is: above-mentioned antifouling flash coating layer is room temperature vulcanized silicone rubber layer (RTV) antifouling flash coating layer.The room temperature vulcanized silicone rubber layer is evenly distributed on the whole surface of dry type discharge coil, and room temperature vulcanized silicone rubber laminar surface resistivity is big, weatherability is strong and adhesion property good.
The utility model improvement further is: the thickness of above-mentioned antifouling flash coating layer is 0.2mm at least, solidifies about 12 hours then at normal temperatures.
The utility model has the advantages that:
Through surface-coated antifouling flush paint at the dry type discharge coil, increased the sheet resistance of discharge coil, reduced the possibility of discharge coil surface generation pollution flashover fault.
Description of drawings
Fig. 1 is the utility model section of structure;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Like Fig. 1, dry type discharge coil shown in Figure 2, comprise iron core 1, primary winding 2, secondary coil 3, terminal 4, secondary terminal 5 and an epoxyresin insulator 6, primary winding 2 is wound on the iron core with secondary coil 3; Primary winding 2 is connected with a terminal 4; Secondary coil 3 is connected with secondary terminal 5; Iron core 1, primary winding 2 and secondary coil 3 utilize the mould vacuum pouring in epoxyresin insulator 6; Compact conformation, volume-diminished, conserve space.Primary winding 2 all adopts enamel covered wire segmentation coiling on iron core 1 to form with secondary coil 3; Iron core 1 surface is with epoxyresin insulator 6, and epoxyresin insulator 6 is an one-time cast-forming, and each several part closely connects; Interior external insulation, epoxyresin insulator 6 surfaces are with antifouling flash coating layer 7.
Antifouling flash coating layer can be room temperature vulcanized silicone rubber layer (RTV) antifouling flash coating layer.With spray gun discharge coil is sprayed, spraying is even, no current mark, breakage, scuffing.The room temperature vulcanized silicone rubber layer is evenly distributed on the whole surface of dry type discharge coil, and room temperature vulcanized silicone rubber laminar surface resistivity is big, weatherability is strong and adhesion property good.The thickness of antifouling flash coating layer is 0.2mm at least, solidifies about 12 hours then at normal temperatures.
