Abstract
The utility model discloses an outdoor reactor with a protective current transformer. The outdoor reactor comprises a mould core, an ethoxyline resin layer and the like. The mould core comprises a reactor coil, the protective current transformer and a supporting piece, wherein the reactor coil is fixed with the protective current transformer via the supporting piece, and is cast into a whole with an incoming line insertion, fixed insertions and a secondary outgoing line insertion of the mould core, is diecast with silica gel outside, and is suitable for outdoor use. The outdoor reactor provided by the utility model can replace a capacitor outgoing line magnetic sleeve, and is integrated with the capacitor to form an integrated high-voltage reactive power compensation unit.
Description
Technical field
The utility model relates to a kind of current limiting reactor, specifically a kind of outdoor type reactor with the protective current instrument transformer.
Background technology
At present,, be the impact of limiting short-circuit current, need series reactor capacitor in the high-pressure reactive compensation field; For avoiding the capacitor internal short-circuit to cause the bigger damage of capacitor to reach damage, often need in capacitor loops, install additional the protective current instrument transformer, as the signal input of Microcomputer Protection with other power equipment of circuit.So, cause whole high-pressure reactive compensation device wiring loaded down with trivial details, volume is bigger, and installation and transportation are all inconvenient, and mostly these reactors, current transformer be indoor equipment, also outdoor protective casing etc. must be set out of doors if use, and cost is higher.
Practical content
For addressing the above problem, the utility model provides a kind of outdoor reactor with the protective current instrument transformer, reaches current transformer and series reactor in one; The whole poured with epoxy resin that adopts, outer die casting silica gel, and can the instead of capacitor insulator; Directly and the capacitor integrated design, thereby the high-pressure reactive compensation device volume is reduced greatly, cost reduces greatly; Wiring is very simple and direct, and in light weight, and transportation is installed very convenient.
The technical scheme of the outdoor reactor of the band protective current instrument transformer of the utility model is following.
A kind of outdoor reactor with the protective current instrument transformer; Comprise core rod; The front end of said core rod is connected with inlet wire inserts or line bank, and the rear end of said core rod is connected with fixedly inserts or fixed leg, and the rear end of said core rod also is connected with secondary outlet inserts or leading-out terminal; Said core rod comprises reactor winding, protective current instrument transformer, strutting piece; Said reactor winding and protective current instrument transformer are fixed together through strutting piece, also comprise epoxy package, and said core rod and inlet wire inserts, fixedly inserts and secondary outlet inserts pour into an integral body through epoxy resin layer.
Wherein, Said core rod also comprises connector, an outlet column; The front end of said reactor winding connects the inlet wire inserts; The rear end of said reactor winding is connected with connector, an outlet column in order, and a said outlet column crosses and lean out the outside of said epoxy package from the middle punching of protective current instrument transformer.
Wherein, said inlet wire inserts links to each other with said reactor winding and is fixed on core tip through epoxy resin layer, and said secondary outlet inserts links to each other with the protective current instrument transformer and is fixed on the core rod bottom through epoxy resin layer.
Wherein, said fixedly inserts has four, is fixed on core rod bottom and symmetrical distribution through epoxy resin layer.
Wherein, outside the poured with epoxy resin layer, go back die casting silica gel layer is arranged.
The beneficial effect of the utility model is following.
The alternative capacitor outlet of the utility model magnetosheath with the capacitor integrated design, constitutes integrated form high-pressure reactive compensation unit; Thereby the high-pressure reactive compensation device volume is reduced greatly, and cost reduces greatly, and wiring is very simple and direct; And in light weight, transportation is installed very convenient.
Description of drawings
Fig. 1 representes that the outdoor reactor of the band protective current instrument transformer that this is practical partly cuts open figure;
Fig. 2 representes the outdoor reactor core rod figure of the band protective current instrument transformer that this is practical.
Wherein, 1 reactance coil; 2 protective current instrument transformers; 3 strutting pieces; 4 fixing inserts; 5 inlet wire inserts; 6 secondary outlet inserts; 7 outlet column; 8 connectors; 9 epoxy resin layers.
Embodiment
Further specify below in conjunction with the outdoor reactor of accompanying drawing the band protective current instrument transformer of the utility model.
Shown in accompanying drawing 1-2; A kind of outdoor reactor with the protective current instrument transformer according to the utility model comprises core rod; Said core rod comprises reactor winding 1, protective current instrument transformer 2, strutting piece 3; Said reactor winding 1 is fixed together through strutting piece 3 with protective current instrument transformer 2, also comprises epoxy resin layer 9, and core rod and affiliated inlet wire inserts 5, fixedly inserts 4 and secondary outlet inserts 6 pour into an integral body through epoxy resin layer 9.Said core rod also comprises connector 8, an outlet column 7; The front end of said reactor winding 1 connects inlet wire inserts 5; The rear end of said reactor winding 1 and connector 8, an outlet column 7 are connected in order, a said outlet column 7 punchings and cross and lean out said epoxy resin layer 9 outsides in the middle of the protective current instrument transformer 2.
Wherein, said inlet wire inserts 5 links to each other with said reactor winding 1 and is fixed on core tip through epoxy resin layer 9, and said secondary outlet inserts 6 links to each other with protective current instrument transformer 2 and is fixed on the core rod bottom through epoxy resin layer 9.Said fixedly inserts 4 has four, is fixed on core rod bottom and symmetrical distribution through epoxy resin layer 9.
Preferably, outside the poured with epoxy resin layer, go back die casting silica gel layer is arranged.
The above only is this practical preferred implementation; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from this practical technique principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as this practical protection range.
