Description
Technical field
The present invention relates to a kind of discharge coil applied in electric system more particularly to a kind of R type discharge coils.
Background technique
In the power system, discharge coil is in parallel with high-voltage parallel capacitor, to capacitor group of releasing in a short time
Residual charge, when discharge coil with it is secondary when, can be as voltage measurement and providing voltage signal for relay system.
Existing discharge coil uses rectangle silicon steel sheet mostly, using lamination or open C sections hearty cord
Structure, in addition there are also a kind of novel amorphous alloy structures.Laminated core processing is cumbersome, and lamination assembly efficiency is low, lamination
Four end faces can have shear burr, and there is assembly air gap between piece and piece, can directly contribute no-load current and loss
Greatly, noise is big;Open C iron-core is because of contact surface injustice, and there are biggish air gaps, can cause iron core strenuous vibration and local magnetic
Saturation causes no-load current and loss sharply to increase, and endangers product safety operation, is easy to cause electric power accident;Amorphous alloy knot
Structure is because the material technology is not yet mature, and material mechanical endurance is very low, and topology layout is unreasonable, is currently only industry and laughs
Head can not be used for power industry and supporting industries concerned without batch generalization and extensive practicability in batches.
Summary of the invention
Aiming at the problems existing in the prior art, a kind of R type discharge coil of the present invention changes conventional iron core closed assembly side
Method, overall structure consolidation, resistance to shorting impact capacity is strong, and no-load current no-load loss is low, and noise is low, and calorific value is low, non-corrosive, nothing
Wedge angle ensure that interiors of products electric fields uniform without point discharge phenomenon, partial discharge meets standard requirements without point stresses.
A kind of R type discharge coil, mainly include R-type core, first winding, secondary winding, HV Terminal, low-voltage terminal,
It is epoxy resin enclosed to form;Wherein first winding and secondary winding are all made of F grades of copper enameled wire coilings and form;Secondary winding coiling
In the R-type core for being surrounded by insulation, first winding is wound on epoxy skeleton;First winding connects HV Terminal, secondary winding
Connect low-voltage terminal;Body is integrally poured using the epoxide resin vacuum of outdoor weather-proof UV resistant;The R-type core is adopted
With one it is whole it is continuous it is continual have grain-oriented Si steel sheet strip, wind on special mold, differed by two-stage or three level widths
Iron core constitute, the high temperature anneal after the completion of iron core coiling, mass-impregnated insulation paint can guarantee that every iron core electric data is equal
It weighs and is fluctuated without obvious, tri-phase unbalance factor is very good.
Detailed description of the invention
Fig. 1 is a kind of R type discharge coil structural schematic diagram;
Fig. 2 is R-type core structure;
1, R-type core in figure;2, first winding;3, secondary winding;4, epoxy resin;5, HV Terminal;6, low-voltage terminal.
Specific embodiment
A kind of the present invention is described in detail with reference to the accompanying drawing R type discharge coil, which mainly includes R type
Iron core 1, first winding 2, secondary winding 3, HV Terminal 5, low-voltage terminal 6, epoxy resin 4 are encapsulated;Wherein first winding 2
The QZY-155 copper enameled wire of F grades of grades is all made of with secondary winding 3 and is formed with special R type coil winding machine coiling;Secondary winding
3 are wound in the R-type core 1 for being surrounded by insulation, and first winding 2 is wound on epoxy skeleton;First winding 2 connects HV Terminal 5,
Secondary winding 3 connects low-voltage terminal 6;Body is integrally formed using 4 vacuum pouring of epoxy resin of outdoor weather-proof UV resistant;It should
Structural key is that R-type core 1 whole continuous continual has grain-oriented Si steel sheet strip to wind on special mold using one
It forms.
