Abstract
The invention discloses a compensation electric reactor, and relates to the technical field of power transmission and distribution, in particular to a structure of an electric reactor. The compensation electric reactor comprises a reactor body. The reactor body comprises an iron core, pressing U-steel and two upper clamping pieces. The upper end of the iron core is arranged between the two upper clamping pieces. Two ends of the pressing U-steel are respectively connected with corresponding upper clamping pieces. The pressing U-steel is arranged above the iron core. An insulating plate and a pressing plate are arranged between the iron core and the pressing U-steel. The pressing plate is arranged above the insulating plate. Nuts are arranged inside the pressing U-steel in a welding mode. Bolts are connected with the nuts in a threaded mode. The bolts are arranged on the pressing U-steel in a penetrating mode. The free ends of the bolts are abutted against the pressing plate. According to the compensation electric reactor, two holes are formed in the middle of traditional U-steel, the nuts are welded on the pressing U-steel, and the pressing plate is arranged below the U-steel in a cushion mode. Then, the insulating plate is used for enabling the iron core to be insulated, the fastening bolts are screwed on the nuts, the pressing plate is integrally pressed, and clamp force is also applied in the middle of the pressing plate. The iron core is pressed stably, vibration is reduced, and noise is lowered.
Description
Technical field
The present invention relates to the technical field of power transmission and distribution, relate in particular to the structure of reactor.
Background technology
The most popular says, can play the thing of the effect of impedance in circuit, 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 energy current-carrying has perception in general sense.Yet the inductance of the long straight conductor of energising is less, and the magnetic field that produces is not strong, and therefore actual reactor is that wire is coiled into the solenoid form, claims air core reactor; Sometimes in order to allow this solenoid have larger inductance, just insert iron core in solenoid, claim iron-core reactor.
The superhigh pressure shunt reactor is improved the several functions of the relevant operation conditions of Power System Reactive Power, mainly comprises:
(1) capacity effect on light zero load or light load circuit is to reduce Frequency Transient Overvoltage.
(2) voltage that improves on 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) reduce power frequency steady state voltage on high voltage bus when unit and system are arranged side by side greatly, be convenient to generator synchronous arranged side by side.
(5) prevent the self-excitation resonance phenomena that generator band long transmission line may occur.
(6) when adopting reactor Neutral grounding via small reactor device, also alternate the and phase earth capacitance of available small reactor compensated line, to accelerate the secondary arc current automatic distinguishing, be 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.
Traditional test class compensation reactor is at the fastening part of unshakable in one's determination and device body, mostly adopt a channel-section steel and folder to fix, be pressed on above iron core column, as long as the surperficial so upper core pressing fixation problem that solves in fact because folder is processed with error, has inclined to one side, oblique when perhaps installing, the capital allows the channel-section steel that clamps formalize, yet clamp place not in place, iron core is play inside, produces noise.The fixture body was all that base plate and locating pin below the device body is congenial in the past, and then stressed clamping up, push down with arm-tie usually, is fixed on oil tank wall.When reactor moved, reactor produced larger shaking force, often greater than this thrust, thereby driving body housing shakes together, cause the noise multiplication, stablize and reduce noise otherwise can only strengthen shell weight, pressure plate structure can only reduce noise and the vibrations that small-sized reactor produces.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of stable iron core is provided, falls low noise compensation reactor.
The object of the present invention is achieved like this: compensation reactor, comprise the device body, the device body comprises iron core, compresses channel-section steel and two upper clamping pieces, upper end unshakable in one's determination is arranged between two upper clamping pieces, the two ends that compress channel-section steel are connected with corresponding upper clamping piece respectively, and compress channel-section steel and be arranged on top unshakable in one's determination, between described iron core and compression channel-section steel, insulation board and pressing plate are set, pressing plate is arranged on the top of insulation board, compress welded nut in channel-section steel, nut thread connecting bolt, bolt are set in and compress on channel-section steel, and the free end of bolt withstands pressing plate.
The present invention is by having opened two holes in the middle of traditional channel-section steel, and the nut of burn-oning, channel-section steel below pad one block pressur plate, and then with an insulation board and core inductance, screw in like this fastening bolt on nut, namely can exert pressure to pressing plate integral body, pressing plate and iron core leave a grade consistent size, can be because of the folder of folder problems affect iron core, and the centre has also applied clamping force, the unshakable in one's determination pressure surely reduced vibrations, reduced noise.
