Description
Technical field
The invention belongs to a kind of electrical equipment, and in particular to a kind of power distribution cabinet shell-type shunt reactor.
Background technology
Traditional reactor typically all includes the air gap gasket of upper core, lower core and centre, and integrated iron core uses silicon steel
Piece.In order to improve the anti-DC capability of product, big air gap is generally required, but small product size can be caused to increase.Air gap gasket one
As formed by plastic injection, be non-magnetic material.It is mainly used in the vibration between iron core above and below suppressing, reduces noise.Due to
Silicon steel is primarily adapted for use in low frequency field, when there is higher hamonic wave or high-frequency direct-current component in circuit system, the filtering of reactor
Effect is deteriorated, while the magnetostriction of silicon steel sheet becomes big, the high frequency noise of reactor becomes big.In addition, termination and the connection of coil
It is general between terminal to be connected by the way of welding, and completed after welding, and completed after welding, the termination of coil and connection
There is gap between terminal, cause contact resistance between coil and connection terminal big, caloric value greatly, influences the use of whole product
Life-span.
The content of the invention
It is an object of the invention to provide a kind of power distribution cabinet shell-type shunt reactor, to solve present in above-mentioned technology not
Foot.
In order to achieve the above object, the technical solution adopted in the present invention is：
A kind of power distribution cabinet shell-type shunt reactor, is by body, line end sleeve pipe, neutral bushing, neutral point lead, line
Cake, winding, lead, pressure releaser summation current transformer composition, described winding two are located at both sides inside body, line respectively
Cake is located between two windings, neutral point lead connecting line cake left upper end, line end sleeve pipe connection neutral point lead, neutral bushing
Downside two ends are respectively arranged with a current transformer, lead connecting line cake upper right side, line end sleeve pipe connection lead, line end sleeve pipe
Downside two ends are respectively arranged with top on the right side of a current transformer, pressure releaser connector body.
Described line cake is to be provided with insulating part on flat rectangular shape, line cake.
Magnetic screen is provided with the outside of described winding.
The present invention is simple in construction, and easy to use, technology is reasonable.Rationally, partial discharge quantity is low for insulation system, tolerance thunder and lightning punching
Hit ability strong, stray loss is low, and no hot-spot, electromagnetic force is small, vibrations and noise are low, uniformity of temperature profile, good cooling results.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of power distribution cabinet shell-type shunt reactor, be by body 1, line end sleeve pipe 2, neutral bushing 3, in
Property is selected lead 4, line cake 5, winding 6, lead 7, the summation current transformer 9 of pressure releaser 8 and constituted, described 6 two difference of winding
Positioned at the inside both sides of body 1, line cake 5 is located between two windings 6, the left upper end of 4 connecting line cake of neutral point lead 5, line end sleeve pipe 2
Neutral point lead 4 is connected, the downside two ends of neutral bushing 3 are respectively arranged with a current transformer 9, and 7 connecting line cake of lead 5 is right
Upper end, the connecting lead wire 7 of line end sleeve pipe 2, the downside two ends of line end sleeve pipe 2 are respectively arranged with a current transformer 9, pressure releaser
The right side of 8 connector body 1 top, described line cake 5 is to be provided with flat rectangular shape, line cake 5 outside insulating part, described winding 6
Side is provided with magnetic screen.
Winding 6 is formed in parallel by two-way, and line end insulation against ground distance is more than the insulation against ground distance of neutral point lead 4, winding 6
Molded insulator arrange that insulating reliability is high along equipotential line, partial discharge quantity is low.The area of shell-type shunt reactor line cake 5 is big,
Electric capacity is big between cake, and the direct-to-ground capacitance of line cake 5 is small, using the molded insulator arranged along equipotential line, with very high tolerance thunder and lightning punching
The ability hit.The magnetic screen of shell-type shunt reactor absorbs magnetic fluxs whole in main empty path, and shield effectiveness is intact.Shell-type is in parallel
Reactor line cake 5 is assembled vertically, and the vertical oil duct on the surface of line cake 5 makes oil have good heat loss through convection, obtains good cooling effect
Really.
