Abstract

The utility model discloses an iron core paralleling reactor. The outer surfaces of a discus and an iron core are provided a resin encapsulating layer. The appearance of a core column is provided with resin composite bodies which are arranged on the appearance and the end parts of a coil and among conductors. A demountable leading wire with an insulating sleeve is connected with an outlet wire terminal of the coil and an insulator which is fixed on a clamping device. The coil and the iron core of the utility model are both firm integration. The utility model has the advantages of small magnitude of partial discharge, high electric strength and mechanical strength, small vibration, and low noise. The utility model solves the problems of gas or liquid leakage, pollution of the environment, explosion hazard, complicated maintenance, etc. of the previous reactor. The utility model is suitable for various substations, underground substations, and urban substations which have high fire prevention explosion proof requirement and no oil.

Description

The resin-insulated dry iron core shunt reactor

The utility model is a kind of power equipment that is used for power transmission and transformation system as inductive reactive power compensation.

The oil immersion iron core shunt reactor has shortcomings such as inflammable, explosive, oil seepage contaminated environment in the prior art; Gas isolated iron core shunt reactor also has easy leakage problem, and the analyte of gas leakage is poisonous, harm personal safety, contaminated environment; Above-mentioned two kinds of reactors have fuel tank and shell, thereby complex structure, weight are big, are difficult for installing, troublesome maintenance.

The purpose of this utility model is to design a kind of do not have oil, non-maintaining, pollution-free, the difficult dry-type iron-core shunt reactor that fires.

The utility model mainly is made up of unshakable in one's determination and coil: last lower yoke unshakable in one's determination is used the folder from top to bottom clamping respectively, stem unshakable in one's determination is to be overlapping and the clamping plate clamping is arranged by a plurality of discuses and gap-gas segregating ring, be connected with ground strip between the discus, the discus outer surface has one deck resin-encapsulate layer, whole stem appearance has resin composite body, and outer surface unshakable in one's determination has one deck resin-encapsulate layer; Be resin composite body between the surfaces externally and internally of coil, upper and lower end parts and the conductor, the side surface of coil has fixing outlet terminal; Cushion block is placed between folder and the coil; Insulator is fixed on the folder; Connect outlet terminal and insulator with the lead-in wire dismountable, that insulating coating is arranged.

Because the utility model usefulness resin and complex thereof are as the main material of insulation and structure, coil and iron core are a firm integral body, thereby partial discharge quantity is little, electrical strength and mechanical strength height, vibrate for a short time, noise is low, does not have any gas and leak of liquid, free from environmental pollution, the basic Maintenance free in the back of putting into operation; Resin is a firing-difficult matter, can spontaneous combustion yet, and the utility model does not have fuel tank and shell, and volume is less.The utility model is specially adapted to city transformer station, underground substation, the quick-fried transformer station that requires height, no oiling of fire prevention such as subway fat.

The utility model iron core 3 is made up of two iron yokes 2 and three stems 9, and iron yoke 2 is used two upper clamping pieces 4 and two lower clamping piece 7 clampings respectively, and lower clamping piece 7 usefulness bolted are on dolly 12, and three block pressur plates, 8 usefulness bolted are on upper clamping piece 4; Each stem 9 of unshakable in one's determination 3 is to be overlapping with a plurality of gap-gas segregating rings 19 and two clamping plate 16 clampings are arranged by a plurality of discuses 20, be connected with ground strip 17 between the discus 20, discus 20 outer surfaces have one deck resin-encapsulate layer 18, whole stem 9 appearances have resin composite body 14, and 3 outer surfaces unshakable in one's determination also have one deck resin-encapsulate layer 18; The surfaces externally and internally of three coils 1, upper and lower end parts and conductor 15 are resin composite body 14 each other, and it is the outlet terminal 5 of one that two or more and its surface cure is arranged on the side surface of each coil 1; Cushion block 10 is that resin composite body 14 forms with electro-insulating rubber is bonding, and 12 cushion blocks 10 are placed between upper clamping piece 4 and the coil 1, and 12 cushion blocks 10 are placed between lower clamping piece 7 and the coil 1, rise and support and insulating effect; 3 insulator 13 usefulness bolted are on upper clamping piece 4; Connect outlet terminal 5 and insulator 13 with the lead-in wire dismountable, that insulating coating is arranged 6.If desired, also can between coil 1 and stem 9, increase insulating cylinder 11.

The used resin composite body of present embodiment is glass fibre and resin, and resin is an epoxy resin.
