Abstract
A compensating reactor relates to the technical field of power transmission and distribution, particularly relates to the structure of a reactor, and comprises a reactor body. The reactor body comprises an upper iron core column, a lower iron core column, an iron core yoke column and an iron core iron yoke, and a plurality of iron cakes are arranged between the upper iron core column and the lower iron core column from bottom to top. The compensating reactor adopts a one-phase single column type, is simple in sleeving, big in margin and convenient in worker operation, effectively lowers flux leakage and reduces loss.
Description
Technical field
The utility model relates to the technical field of power transmission and distribution, relates in particular to the structure of reactor.
Background technology
The most popular says, can in circuit, play the thing of the effect of impedance, is called reactor.Reactor also is inductor, will produce magnetic field in its occupied certain space scope during a conductor energising, so the electric conductor of all ability current-carrying all has perception in general sense.Yet the inductance of the long straight conductor of energising is less, and the magnetic field that is produced is not strong, and therefore actual reactor is a lead coiled solenoid form, claims air core reactor; Sometimes in order to let this solenoid have bigger inductance, just in solenoid, insert iron core, claim iron-core reactor.
The superhigh pressure shunt reactor has the multiple function of improving the relevant operation conditions of power system reactive power power, mainly comprises:
(1) capacity effect on light zero load or the light load circuit is to reduce Frequency Transient Overvoltage.
(2) voltage that improves on the long power transmission line distributes.
(3) make reactive power in-situ balancing as far as possible in the light hours circuit, prevent that the unreasonable mobile while of reactive power from also having alleviated the power loss on the circuit.
(4) when unit and system are arranged side by side greatly, reduce power frequency steady state voltage on the high voltage bus, be convenient to generator synchronous arranged side by side.
(5) prevent the self-excitation resonance phenomena that the generator belt long transmission line possibly occur.
(6) when adopting the reactor neutral point through little reactance grounded device, the alternate and phase earth capacitance of also available little reactor compensated line is extinguished to quicken secondary arc current automatically, is convenient to employing.
Reactor divides from function can be divided into current limliting and compensation, and compensation reactor generally is connected between the end and ground of ultra high-tension transmission line.In testing equipment, compensation reactor plays filtering and inactive power compensation.
There is following defective in present compensation reactor: 1, a test type compensation reactor internal structure still adopts original single-phase queen post unshakable in one's determination, adopts the twin coil parallel connection to draw.Twin coil suit trouble, lead-in wire parallel connection difficulty runs into especially that electric current is big, when conductor cross-section is thick, and the workman bends lead and requires great effort very much, even can't bend, and the weldering that also will carry out lead connects, and very inconvenience is installed.
2, the stack mode of iron core.The most step that still adopts in the past of now domestic test class compensation reactor manufacturing, half straight half oblique method connects, and under this connecting mode, magnetic flux is easy to generate loss at seam crossing, causes local overheating unshakable in one's determination.
3, air gap unshakable in one's determination chooses.The main material of present domestic employing test type compensation reactor air gap remains epoxy plate, also has much to use instead to be laminated paper board.This type material all belongs to organic material, and material internal is less exists impurity, also has when cleaning to be not easy to remove all burrs, also exists oven dry not exclusively during oven dry, and situation such as humidity are arranged, and can cause noise unshakable in one's determination to become big like this, and bigger office's cloth discharge is arranged.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, provide a kind of easy for installation, reduce leakage field, reduce the compensation reactor of loss.
The purpose of the utility model is achieved in that a kind of compensation reactor; Comprise the device body; Said device body comprises upper iron core stem, following stem unshakable in one's determination, yoke post unshakable in one's determination and iron yoke unshakable in one's determination, between upper iron core stem and following stem unshakable in one's determination, sets gradually several discuses from the bottom to top.
The utility model adopts single-phase single column, and suit is simple, and nargin is big, and the workman is easy to operate, and this version also effectively reduced leakage field, has reduced loss.
Inside and outside two groups of micanite cushion blocks of evenly arranging are set respectively between adjacent two discuses of the utility model, and traditional air gap of avoiding is choosing of organic material, and the stone cushion block of selecting slick and sly polishing for use is as gap between discus; Because the stone cushion block can not cause internal influence, and adopt a plurality of circumference uniform distributions for the insulation material; Increased oil duct for iron core more cleverly; Be convenient to heat radiation, reduce temperature rise, eliminated the partial discharge factor that organic material brings.
Said yoke post unshakable in one's determination comprises upper iron core yoke post and following yoke post unshakable in one's determination, and upper iron core yoke post is arranged on down the top of yoke post unshakable in one's determination.Adopt radial type core stack method, yoke post unshakable in one's determination breaks off up and down, put end unshakable in one's determination when splicing uneven convexity externally cause silicon steel sheet at internal modification when also having avoided the workman to knock finishing, influence performance.Adopt this stack mode, more effectively reduced stray loss unshakable in one's determination.

Fig. 3 be among Fig. 2 A-A to view.
Embodiment
As shown in Figure 1, be compensation reactor, mainly comprise fuel tank 2 and device body 1.
Like Fig. 2, shown in 3, device body 1 comprises upper iron core stem 4, stem down unshakable in one's determination 8, yoke post 5 unshakable in one's determination and iron yoke 3 unshakable in one's determination, and yoke post 5 unshakable in one's determination comprises upper iron core yoke post 5-1 and following yoke post 5-2 unshakable in one's determination, and upper iron core yoke post 5-1 is arranged on down the top of yoke post 5-2 unshakable in one's determination.Between upper iron core stem 4 and following stem 8 unshakable in one's determination, set gradually several discuses 6 from the bottom to top, inside and outside two groups of micanite cushion blocks 7 of evenly arranging are set respectively between adjacent two discuses 6.
