Abstract
The utility model discloses a reactor cast by epoxide resin for high-voltage tests (see the attached drawing), which comprises an upper coil 1, an epoxide resin encapsulated layer 2, an annular groove 3, a lower coil 4, a framework tube 5 and a magnet core 6. The reactor is characterized in that: after the reactor is encapsulated by epoxide resin, the annular groove 3 is formed between the upper coil 1 and the lower coil 4, thus, the defects of bubbling, cracking, and the like due to a large amount of epoxide resin accumulated in the annular groove of a previous reactor are avoided, and the surface creepage distance between the upper coil and the lower coil is increased so as to improve the insulation level of the reactor.
Description
Technical field
The utility model relates to the parts of power equipment AC voltage withstand test the complete sets of equipment, especially the parts of frequency modulation type series resonance Withstand test device.
Background technology
Before circuit on power system puts into operation or after the maintenance, all to test to the state of insulation of force device or equipment.Wherein, ac voltage withstanding is a basic and important test.Alternating current withstand voltage test method probably is divided into three kinds, excutes a law promptly outward, actinobolia and the resonance method.The resonance method is to utilize reactor and test specimen to form the LC loop, makes the loop reach resonance condition by transferring modes such as sense or frequency modulation, thereby produce high voltage on test specimen.Frequency modulation type series resonance Withstand test device promptly is to utilize mode of frequency regulation to realize that the resonance method is withstand voltage, and reactor wherein adopts fixed reactor.
For the ease of carrying and stack, fixed reactor adopts the dry construction of poured with epoxy resin mostly.But poured with epoxy resin formula reactor is in the past limited by moulding, and withstand voltage is lower, and insulation level generally is no more than 33kV, and the scope of application is below the 35kV electric pressure.
Summary of the invention
The purpose of this utility model is to provide a kind of reactor that can tolerate high voltage, makes it to be applicable to the AC voltage withstand test of 110/220kV electric pressure power equipment.For achieving this end, the utility model is divided into two reactor winding, places the mould casting epoxy resin.Coil behind resin-encapsulate from the appearance, at the middle part, form an annular groove between two coils up and down, avoided in the past reactor to pile up a large amount of resins and produce insulation defects such as bubble, crackle at groove, and increased the surface creepage distance between two coils up and down, thereby the reactor insulation level is improved, be up to 66kV
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment 1, and accompanying drawing 2 is structural representations of the utility model embodiment 2.
Embodiment
Embodiment 1: referring to a kind of high-voltage test poured with epoxy resin reactor shown in the accompanying drawing 1, comprise coil 1, epoxy resin enclosed layer 2, annular groove 3, lower coil 4, tube of skeleton 5, unshakable in one's determination 6.Its concrete structure is: go up coil 1 and lower coil 4 and oppositely be wound on the tube of skeleton 5, place the mould casting epoxy resin; Epoxy resin enclosed layer 2 will be gone up coil 1 and lower coil 4 complete parcels equably, and form annular groove 3; In tube of skeleton 5, insert 6 assemblings unshakable in one's determination and make reactor.
Embodiment 2: referring to a kind of high-voltage test poured with epoxy resin reactor shown in the accompanying drawing 2, comprise coil 21, epoxy resin enclosed layer 22, annular groove 23, lower coil 24, tube of skeleton 25, unshakable in one's determination 26.Its concrete structure is: go up coil 21 and lower coil 24 and oppositely be wound on the tube of skeleton 25, place the mould casting epoxy resin; Epoxy resin enclosed layer 22 will be gone up coil 21 and lower coil 24 complete parcels equably, and form annular groove 23; In tube of skeleton 25, insert 26 assemblings unshakable in one's determination and make reactor.
