Abstract
A kind of R types discharge coil, mainly including R-type core, first winding, secondary winding, HV Terminal, low-voltage terminal, epoxy resin enclosed form；Wherein first winding and secondary winding are formed using F level copper enameled wire coilings；Secondary winding is wound in the R-type core for being surrounded by insulation, and first winding is wound on epoxy skeleton；First winding connects HV Terminal, secondary winding connection low-voltage terminal；Device body is integrally formed using the epoxide resin vacuum cast of outdoor weather-proof UV resistant；The R-type core has grain-oriented Si steel sheet strip using a whole piece is continuously continual, wind, be made up of the iron core of two-stage or three level widths not etc., overall structure consolidation on special mould, resistance to shorting impact capacity is strong, no-load current open circuit loss is low, and noise is low, and caloric value is low, non-corrosive, without wedge angle without point stresses, interiors of products electric fields uniform is ensure that without point discharge phenomenon, partial discharge meets standard requirement.
Description
Technical field
It the utility model is related to a kind of discharge coil being applied in power system, more particularly to a kind of R types discharge coil.
Background technology
In power system, discharge coil is in parallel with high-voltage parallel capacitor, to capacitor bank of releasing in a short time
Residual charge, when discharge coil with it is secondary when, can double 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 also a kind of new non-crystaline amorphous metal structure.Laminated core processing is cumbersome, and lamination efficiency of assembling is low, lamination
Four end faces can have shear burr, and assembling air gap between piece and piece be present, can directly contribute no-load current and loss
Greatly, noise is big；Larger air gap be present, strenuous vibration unshakable in one's determination and local magnetic can be caused in open C iron-core because contact surface is uneven
Saturation, cause no-load current and loss drastically to raise, endanger product safety operation, easily trigger electric power accident；Non-crystaline amorphous metal knot
Structure is because the material technology is not yet ripe, and material mechanical endurance is very low, and topology layout is unreasonable, is currently only industry and laughs
Head, without batch generalization and extensive practicality, power industry and supporting industries concerned can not to be used in batches.
The content of the invention
For problems of the prior art, a kind of R types discharge coil of the utility model changes conventional iron core and folded
Dress method, overall structure consolidation, resistance to shorting impact capacity is strong, and no-load current open circuit loss is low, and noise is low, and caloric value is low, does not give birth to
Rust, no wedge angle ensure that interiors of products electric fields uniform without point discharge phenomenon, partial discharge meets standard requirement without point stresses.
A kind of R types discharge coil, mainly including 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 formed using F level copper enameled wire coilings；Secondary winding coiling
On the R-type core of insulation is surrounded by, first winding is wound on epoxy skeleton；First winding connects HV Terminal, secondary winding
Connect low-voltage terminal；Device body is integrally formed using the epoxide resin vacuum cast of outdoor weather-proof UV resistant；The R-type core is adopted
There is grain-oriented Si steel sheet strip with a whole piece is continuously continual, wound on special mould, by two-stage or three level widths
Composition unshakable in one's determination, the high temperature anneal after the completion of coiling unshakable in one's determination, mass-impregnated insulation paint, can guarantee that every electric data unshakable in one's determination is equal
Weigh and very good without obvious fluctuation, tri-phase unbalance factor.
Brief description of the drawings
Fig. 1 is a kind of R types discharge coil structural representation；
Fig. 2 is R-type core structure；
1, R-type core in figure；2nd, first winding；3rd, secondary winding；4th, epoxy resin；5th, HV Terminal；6th, low-voltage terminal.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings a kind of R types discharge coil, the discharge coil mainly wraps
R-type core 1, first winding 2, secondary winding 3, HV Terminal 5, low-voltage terminal 6, epoxy resin 4 is included to encapsulate and form；Wherein once
Winding 2 and secondary winding 3 use the QZY-155 copper enameled wires of F level grades and formed with special R type coil winding machine coilings；Two
Secondary winding 3 is 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 high pressure
Terminal 5, secondary winding 3 connect low-voltage terminal 6；Device body is integrally using the vacuum pouring of epoxy resin 4 of outdoor weather-proof UV resistant
Form；The structural key is that R-type core 1 has grain-oriented Si steel sheet strip in special mould using a whole piece is continuously continual
Upper winding forms.
