Description
Technical field
The present invention relates to a kind of reactor power extraction coil magnetic shunt paths, belong to large-scale reactor manufacturing equipment technical field.
Background technology
Energy reactor is taken out, is to cover coil, referred to as power extraction coil on the magnetic circuit of conventional parallel reactor iron yoke.According to electricity
Magnetic induction principle, power extraction coil can generate electric current, export energy as power supply, electricity consumption is provided for substation.Therefore, taking out can electricity
The major function of anti-device is identical as common shunt reactor --- and the capacitance current of compensation power transmission line prevents the liter of line end voltage
It is high；Secondary function be exactly from circuit take out can be power station power supply.
, can be by power extraction coil short circuit when short circuit occurs for electricity consumption side, it includes in reactor iron yoke to make its magnetic flux surrounded
Magnetic flux all change paths, be formed into a loop on the outside of the power extraction coil.This affects the reactance value of reactor, to change
Impedance in power grid, it is possible to which huge injury is caused to power network line.
Reduce power extraction coil short circuit influences for caused by reactor, ensures that the major function of reactor operation is the present invention
It solves the problems, such as.
Invention content
It is an object of the present invention to provide a kind of reactor power extraction coil magnetic shunt paths, using the magnetic conduction silicon rolled along flow direction
Steel disc is piled into C-shaped magnetic shunt path, and power extraction coil is coated, and reduce power extraction coil short circuit influences for caused by reactor,
Efficiently solve the above problem present in background technology.
The technical scheme is that：A kind of reactor power extraction coil magnetic shunt path, including reactor iron yoke, power extraction coil
And magnetic shunt path, the magnetic shunt path are constituted for magnetic conduction silicon steel sheet stack, monolithic magnetic conduction silicon steel sheet rolling direction is C along flow direction
Shape is arranged inside and outside reactor iron yoke, will be enclosed on the outside of power extraction coil and in the upper and lower ends of reactor iron yoke lateral parts
Firmly.
The width of magnetic shunt path matches with reactor iron yoke thickness.
The beneficial effects of the invention are as follows：Reduce influence of the power extraction coil short circuit for reactor reactance value, protection reactor
Basic performance；Improve power extraction coil anti-short circuit capability.

Specific implementation mode
Below in conjunction with attached drawing, by embodiment, the invention will be further described.
A kind of reactor power extraction coil magnetic shunt path, including reactor iron yoke 1, power extraction coil 2 and magnetic shunt path 3, the magnetic
Branch 3 is constituted for magnetic conduction silicon steel sheet stack, and monolithic magnetic conduction silicon steel sheet rolling direction is C-shaped along flow direction, is arranged in reactor
Inside and outside iron yoke 1, surrounded by 2 outside of power extraction coil and in the upper and lower ends of 1 lateral parts of reactor iron yoke.
The width of magnetic shunt path 3 matches with 1 thickness of reactor iron yoke.
In practical applications, by magnetic conduction silicon steel sheet stack at section be C-shaped magnetic shunt path, be arranged in inside and outside reactor iron yoke
Both sides surround in three faces power extraction coil on the outside of the upper and lower ends of reactor iron yoke lateral parts and coil.Magnetic conduction silicon steel sheet is wide
Degree is identical as reactor iron yoke thickness, and monolithic magnetic conduction silicon steel sheet rolling direction is C-shaped along the direction of magnetic flux, if dry plate magnetic conduction silicon steel
Piece stack forms strip.
When power extraction coil is short-circuited, the magnetic flux in reactor iron yoke is on the outside of power extraction coil.Due to magnetic conduction silicon steel sheet
Magnetic resistance very little, magnetic flux can be imported into the magnetic shunt path of C-shaped, be then return in reactor iron yoke.Magnetic shunt path as be oriented to, allow magnetic flux also
It is to form closed circuit in the magnetic conduction silicon steel sheet of low magnetic resistance, to reduce influence of the magnetic circuit variation to reactance value, also just drops
Low influence of the power extraction coil short circuit for reactor reactance, ensure that the effect of electric reactor compensation capacitance current.Meanwhile magnetic point
Power extraction coil has been embraced in three face of road, and its mechanical strength is higher, and when power extraction coil short circuit, magnetic shunt path can inhibit power extraction coil
Axial deformation, improve its firmness.
