Abstract

The utility model relates to an electric reactor with a good heat dissipation property. The electric reactor comprises an iron core and multiple windings wound on the iron core, wherein each winding comprises at least one conductor layer, or a skeleton and at least one conductor layer wound on the skeleton, and each conductor layer is formed by winding at least one insulated conductor circle by circle. The electric reactor with the good heat dissipation property has the advantages that no insulating layer is arranged between the conductor layers of the windings of the electric reactor, the heat dissipation property and the overload capacity of the windings are improved, the service life of the electric resistor is prolonged, the consumption of chemical materials is reduced, and the electric reactor plays an important role in energy conservation and emission reduction.

Description

The reactor that heat dispersion is good

Technical field

The utility model relates to a kind of reactor, particularly the good reactor of a kind of heat dispersion.

Background technology

Reactor is comprised of coil and iron core, and its major function comprises: the capacity effect on (1) light zero load or light load circuit, to reduce Frequency Transient Overvoltage; (2) voltage improving on long power transmission line distributes; (3) make reactive power in light hours circuit in-situ balancing as far as possible, prevent that the unreasonable mobility of reactive power from also having alleviated the power loss on circuit simultaneously; (4) when unit and system are arranged side by side greatly, reduce power frequency steady state voltage on high voltage bus, 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 trend automatic distinguishing of powering, is convenient to employing.Due to its important function in circuit, need to constantly improve it.The coil of existing reactor comprises the conductor layer being turned to by wire and is arranged on the insulating barrier between conductor layer, existence due to insulating barrier, reduced heat radiation and the overload capacity of coil, manufactured insulating barrier simultaneously and need to use a large amount of chemical materials, resource has been caused to certain waste.

Summary of the invention

The purpose of this utility model is to provide the reactor that a kind of heat dispersion is good.

For achieving the above object, the technical solution adopted in the utility model is: the reactor that a kind of heat dispersion is good, it comprises iron core, a plurality of coil being set around on described iron core, coil described in each by least one layer conductor layer, formed or by skeleton and at least the conductor layer of one deck winding on described skeleton form, the conductor layer described in every layer suffers a circle coiling by least one insulated conductor one circle and forms.

Optimize, the cross section of described wire is rectangle, the broad side surface that the side at the place, both sides that this rectangle length of side is longer is wire, the narrow side that the side at the place, both sides that the length of side is shorter is wire, described wire turns to after conductor layer, and the inwall of conductor layer and outer wall are respectively two narrow sides of wire.

Optimize, described iron core be a day font iron core, described coil have three and distinguish winding and three stem stems of described iron core on.

Because technique scheme is used, the utility model compared with prior art has following advantages: naked layer between the conductor layer of the coil of reactor, thermal diffusivity and the overload capacity of coil have been improved, extended the life-span of reactor, reduced the use of chemical material, for energy-saving and emission-reduction play a significant role.
