Abstract
The invention discloses a three-phase integrated parallel reactor. An iron core is an iron core in a shape like a Chinese character of 'mu'; each phase of winding in a three-phase winding is arranged in the iron core and is fixedly clamped by an upper clamping piece, a lower clamping piece, a tension screw and a bolt connected in an insulating manner; each phase of winding consists of a coil wound by coil cakes and formed insulating members positioned between every two coil cakes and adopts two paths of parallel structures; the head end lead-out wire and the tail end lead-out wire of each phase of coil are respectively used for leading out the phase windings and then are connected with each phase of head end casing and tail end casing; and tail end casing lug plates are connected through a ground lead and then are led to the lower part of an oil tank. The three-phase integrated parallel reactor has the advantages of light weight, small size and greatly-reduced cost; and according to the three-phase integrated parallel reactor, capacitance current can be compensated to a line, the voltage rise of a power grid is inhibited, the power frequency voltage rise in an ultra-high voltage long-distance power transmission system is avoided and the power transmission system is enabled to work more stably.
Description
Technical field
The present invention relates to a kind of shunt reactor.
Background technology
The shunt reactor of existing voltage levels all adopts phase structure, adds the neutral point reactor by three single-phase reactors again and is connected into star, through neutral point reactor ground connection.Each single-phase reactor all need be equipped with the assembly that a cover is made up of main group such as terminal box, oil conservator, pasta thermometer, winding temperature gage, pressure releaser made, Buchholz relay, dehydrating breather, couplet pipe and cooling device parts; Four need to be equipped with 4 grip assemblies; Its overall weight is heavy; Cost is high, is difficult for installing; In superhigh pressure long distance power transmission system, because the capacity effect of circuit often causes that power-frequency voltage raises, but transmission line does not allow to move in long-term surpassing under the situation of rated voltage 5%.
Summary of the invention
The object of the invention is exactly to solve the problems referred to above that exist in the prior art, provides that a kind of overall weight is light, cost is low; Can suppress the three-phase integrated shunt reactor that line voltage raises to the line build-out capacitance current.
For addressing the above problem; Technical solution of the present invention is: a kind of three-phase integrated shunt reactor, and it comprises fuel tank, iron core, three phase windings, upper clamping piece, lower clamping piece, head end sleeve pipe, terminal sleeve pipe, is fixed on fuel tank outside terminal box, oil conservator, pasta thermometer, winding temperature gage, pressure releaser made, Buchholz relay, dehydrating breather, couplet pipe and cooling device; Iron core is an order font iron core, and every phase winding of three phase windings places in the iron core respectively, and by upper clamping piece, lower clamping piece, draw screw rod to be fixedly clamped with the core through screw rod that is connected of insulation; Every phase winding is made up of the coil of line cake coiling and the molded insulator between online cake respectively; Every phase coil adopts the two-way parallel-connection structure, after the head end lead-out wire of every phase coil and terminal lead-out wire are drawn phase winding respectively, is connected with terminal sleeve pipe with every head end sleeve pipe mutually, and each terminal conduit connection sheet causes the fuel tank bottom after connecting through ground lead.
Because the present invention has made integrative-structure with the iron core and three phase windings of parallel three phase reactor; It is installed in the fuel tank; Only need to be equipped with the assembly that a cover is made up of main group such as terminal box, oil conservator, pasta thermometer, winding temperature gage, pressure releaser made, Buchholz relay, dehydrating breather, couplet pipe and cooling device parts, compare and can practice thrift three grip assemblies with add star shunt reactor that the neutral point reactor forms by three single-phase reactors, and iron core employing " order font " structure; Save three iron core column; Iron core weight significantly reduces, so overall weight of the present invention is light, volume is little, cost significantly reduces.The present invention can suppress line voltage and raise to the line build-out capacitance current, can not cause that in superhigh pressure long distance power transmission system power-frequency voltage raises, and makes the transmission system more stable work.Compact conformation of the present invention, good looking appearance.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done and to further describe.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, present embodiment comprises fuel tank 4, comprise iron core 13, three phase windings 12,14,15, upper clamping piece, lower clamping piece, head end sleeve pipe 8, terminal sleeve pipe 3, be fixed on fuel tank 4 outside terminal box 9, oil conservator 1, pasta thermometer 20, winding temperature gage 21, pressure releaser made 7, Buchholz relay 2, dehydrating breather 5, join pipe and cooling device.Iron core 13 is an order font iron core, and every phase winding 12,14,15 of three phase windings places respectively in the iron core 13, and by upper clamping piece, lower clamping piece, draw screw rod 11 to be fixedly clamped with the core through screw rod 10 that is connected of insulation.Every phase winding 12,14 or 15 is respectively by two groups of line cakes (1), (2), (3) ... (N) coil 18 of coiling and the molded insulator between online cake are formed.Every phase coil 18 adopts the two-way parallel-connection structure: two groups of line cakes (1), (2), (3) ... (N) head end is connected with head end, terminal and terminal the connection; Head end after the connection is drawn the head end lead-out wire 17 and terminal lead-out wire 16 that forms coil by lead-in wire respectively with terminal.After the head end of every phase coil and terminal lead-out wire 17,16 are drawn each phase winding respectively, connect the head end sleeve pipe 8 and terminal sleeve pipe 3 of each phase, each mutually terminal sleeve pipe 3 lug plate all is connected on the ground lead, causes fuel tank 4 bottoms again.6 is the accident fuel outlet valve.
