Description
The utility model relates to a kind of automatically controlled ground connection arc-extinction device, belongs to a kind of AC reactor that adopts arc suppression coil to adjust perceptual offset current.
The method of the arc suppression coil adjustment perception offset current of domestic production at present has two kinds: a kind of is the number of turn that arc suppression coil is regulated in classification; Another kind is an air gap of regulating the iron core of arc suppression coil.These two kinds of methods all adopt mechanical drive mode to regulate, and its common shortcoming is: arc suppression coil is bearing under the condition of rated voltage and can not adjust, and governing speed is slow, and requires to adopt precision mechanical transmission mechanism, big, the poor reliability of vibrating noise accurately.Therefore can only realize the static compensation of electric network capacitance and current, can not realize the requirement of dynamic compensation, simultaneously,, also inconvenience of wiring is installed because grounding transformer and arc suppression coil are two body structures.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and provide a kind of hold automatically controlled arc suppression coil and meander configuration grounding transformer in one, can regulate perceptual offset current and the fast automatically controlled ground connection arc-extinction device of governing speed continuously.
The purpose of this utility model is achieved in that it is made of fuel tank, grounding transformer, automatically controlled arc suppression coil three parts.Grounding transformer is tightened to one by vertical connecting rod and automatically controlled arc suppression coil, is loaded in the same fuel tank; The iron core of automatically controlled arc suppression coil is three pillar type, and middle cornice air gap is set with the interchange main coil on center pillar, two side columns suit AC magnetism balance coil and DC control coil; The polarity of each coil and the mode of connection meet routine principle down: two side columns AC magnetism balance coil exchanges main coil with center pillar after with each end parallel connection and forward connects the DC control coil differential concatenation on the two side columns.
The utility model compared with prior art has the following advantages and result of use:
1, since this device have bear under the rated voltage condition, perceptual offset current is adjustable continuously, governing speed is fast, can realize electric network capacitance and current from the motion tracking dynamic compensation.
2, owing to adopted the AC magnetism balance coil, eliminated AC harmonic and can improve adjustable range influence, the while of DC control circuit.
3, grounding transformer and automatically controlled arc suppression coil are structure as a whole, and therefore are convenient to install and wiring.
4, bolt adopts no punching point plate structure, good manufacturability, is easy to processing in the band air gap.
The explanation of accompanying drawing drawing:
Accompanying drawing is structural representation of the present utility model and wiring schematic diagram.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
This device is made up of fuel tank (1), grounding transformer (2), automatically controlled arc suppression coil (3) three parts, the device body of grounding transformer (2) places automatically controlled arc suppression coil (3) device face on one's body, be tightened to one by vertical connecting rod, be contained in the same fuel tank (1), the coil of grounding transformer (2) adopts the indentation connection, and artificial neutral point and perceptual offset current path are provided.The iron core of automatically controlled arc suppression coil (3) adopts three pillar type, center pillar (7) has the no punching structure of air gap (8), center pillar (7) is gone up suit and is exchanged main coil (9), two side columns (5) suit AC magnetism balance coil (4) and DC control coil (6), the polarity of each coil must meet following principle with the mode of connection: the AC magnetism balance coil (4) on (1) two side columns (5) with each end parallel connection after with center pillar (7) on the main coil (9) that exchanges forward connect, guarantee exchange flux φ and φ
1The direction consistency; (2) the DC control coil (6) on the two side columns (5) is answered differential concatenation, and the alternating current impression electromotive force of two coils is cancelled out each other.Concrete mode of connection is: the head end of two AC magnetism balance coils (4) also connects 0 phase sleeve pipe, exchanging the head end of main coil (9) and the neutral point 0 of grounding transformer (2) joins, AC magnetism balance coil (4) connects together with the tail end that exchanges main coil (9), two DC control coil (6) tail ends phase also connects, and head end meets sleeve pipe a
