Description
Technical field:
The present invention relates to a kind of reactor more particularly to a kind of electromagnetic balance type REgulatable reactors.
Background technique:
The electric power application fields such as reactor is mainly adjusted in power grid as reactive compensation, voltage, fault current inhibits
Key equipment, and reactive balance be power grid security, stabilization, economical operation important guarantee, for super-pressure long distance powedr transmission net
It is especially true；Research has shown that the capacity of REgulatable reactor can not only change, smooth adjusting system with the size of transimission power
The reactive power of system realizes flexible transmission, can also inhibit power frequency and switching overvoltage, line loss is reduced, so as to significantly
The stability and safety of raising system, therefore REgulatable reactor has remarkable effect for improving Operation of Electric Systems performance；It can
Reactor is adjusted to be broadly divided into mechanical, magnet controlled, power switch formula, transformer type etc., mechanical REgulatable reactor is with respect to it
His REgulatable reactor has that structure is simple, at low cost, harmonic content is low, high reliability；But mechanical regulative reactance
The adjustable range of device is not high, cannot achieve and is adjusted by maximum value to zero, degree of regulation is also relatively low.
Summary of the invention:
The purpose of the present invention is to provide a kind of adjustment process is reliable, stablize, simply；It, can be with without additional impact and harmonic wave
It is adjusted to zero from maximum value, the electromagnetic balance type REgulatable reactor that the gear of adjusting can freely be set.
The present invention is implemented by following technical solution: electromagnetic balance type REgulatable reactor comprising on iron core and the iron core
The positive coil of winding, on the iron core also winding be equipped with it is identical as the positive coil turn, around to opposite reverse line
Circle；Adjacent described positive coil one end is connect with described reverse winding one end；The other end of the reverse winding is cut with end
Change the connection of switch one end；More than one tap is equipped on the reverse winding；Each tap and a tap changing
One end of switch connects；The other end of the other end of end switching switch and each tap switch with it is described
The other end of positive coil connects；The end switching switch and the tap switch reciprocal interlocking.
The iron core is any one of C-shaped iron core, E shape iron core, R shape iron core, stick iron core or annular core.
Advantages of the present invention: adjustment process is reliable, stablizes, simply；Without open circuit process in adjustment process, circuit work is steady
Fixed, no additional impact and harmonic wave can be adjusted to zero from maximum value, and the gear of adjusting can freely set that (fineness of adjusting can
Control).

Specific embodiment:
As depicted in figs. 1 and 2, electromagnetic balance type REgulatable reactor comprising the positive line wound on iron core 1 and iron core 1
Circle 2, on the iron core 1 also winding it is identical as described forward direction 2 the number of turns of coil, around to opposite reverse winding 3；Iron core 1 is R shape
Iron core；Or as shown in figure 3, iron core 1 is annular core；Or as shown in figure 4, iron core 1 is E shape iron core；Or as shown in figure 5, iron core 1
For stick iron core, the cross section of stick iron core is round or arbitrary polygon；Or as shown in fig. 6, iron core 1 is C-shaped iron core；It is adjacent
One end of the positive coil 2 connect with one end of the reverse winding 3；The other end of the reverse winding 3 is cut with end
Change the connection of 4 one end of switch；Tap 5 there are two being set on the reverse winding 3；Each tap 5 is opened with a tap changing
Close 6 one end connection；The other end of the other end of end switching switch 4 and each tap switch 6 is and institute
State the other end connection of positive coil 2；The end switching switch 4 and 6 reciprocal interlocking of tap switch.
Working principle: according to the law of electromagnetic induction and the right-hand rule, when current direction is identical, positive coil 2 and around to
The induced magnetic field generated in opposite reverse winding 3 is contrary, the effect of offseting each other, the magnetic field strength etc. of reactor entirety
Magnetic field is generated in positive coil 2 and reverse winding 3 generates the vector sum in magnetic field；
Positive coil 2 is always on work, switches switch by the switching end of reciprocal interlocking on switching reverse winding 3
4 and tap switch 6, it realizes the magnetic field size to offset each other with 3 magnetic field of reverse winding that adjustment reverse winding 3 generates, produces
The effect of raw adjustment reactor global magnetic field intensity, and then reactor is made to generate different reactance；Wherein, it is switched when end switches
4 are closed, and the induced magnetic field generated in positive coil 2 and reverse winding 3 is cancelled out each other, and reactor is integral into short-circuit condition.
