Abstract

The utility model discloses a dry-type half-iron-core reactor, which is composed of an A-phase reactor, a B-phase reactor and a C-phase reactor. A single-phase reactor includes a reactor solenoid and an iron core, wherein the iron core is disposed in the hollow of the reactor solenoid l, the height of the iron core is less than that of the reactor solenoid, and the iron core is longitudinally symmetrical by centering on the reactor solenoid. The iron core is hollow cylinder formed by radially overlapping sheet structures made of high permeable materials, and the iron core is integrally cast via vacuum epoxy resin cast. The dry-type half-iron-core reactor has fine integration, small operational vibration and low noise, can be directly used outdoors without limitation of any environmental conditions, and further is energy-saving in operation and convenient in installation.

Description

A kind of dry type half core reactor

Technical field

The utility model relates to the reactor in a kind of power industry, more precisely relates to a kind of dry type half core reactor.

Background technology

Along with the development of China's modernization construction, the paces of development of the West Regions are accelerated, the power industry development is maked rapid progress.Power grid construction, enlarging and transformation have caused the urban and rural power grids load constantly to increase, the reactor with T-shaped core of traditional structure, and its core material consumption is big, cost height, complicated in mechanical structure.Especially a plurality of air gaps that distribute on iron core column produce vibration when being accompanied by huge electromagnetic force and causing moving big and noise is big.Because its iron core is to be exposed among the air, can not be used for the open air simultaneously.And dry-type air-core reactor, because magnetic flux density is low in the coil, so small product size is big, and the lead consumption is just many, and loss is also just corresponding bigger.

The utility model content

In order to address the above problem, the utility model provides that a kind of material consumption is little, cost is low, simple in structure and can directly be used in the open air, not limited by any environmental condition, vibrates the dry type half core reactor little, that noise is low, volume is little simultaneously.

The purpose of this utility model realizes by following scheme: a kind of dry type half core reactor, comprise reactor A phase, reactor B phase, reactor C phase, wiring fixing plate, phase insulation and insulation against ground, it is characterized in that: described reactor A phase, reactor B reach reactor C mutually and include reactor line bag and iron core mutually, described iron core is arranged among described reactor line bag hollow, described iron core height is lower than the height of described reactor line bag, and symmetrical up and down with reactor line bag center.

In the such scheme, described iron core is made by high permeability material.

In the such scheme, the shape of described iron core be one by the made sheet of high permeability material through the radial hollow cylinder that builds up, and iron core integral body is the vacuum epoxy casting.

Adopt this kind dry type half core reactor, the diameter of coil can dwindle significantly, and the lead consumption significantly reduces, and loss also reduces thereupon significantly; And globality is fine, during operation vibration little, noise is low, especially iron core column is not limited by any environmental condition through the moulding of overall vacuum epoxy casting, can directly be used in the open air again after special safeguard procedures are handled, energy saving in running is easy for installation.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model dry type half core reactor is further described:

Among Fig. 1, reactor A phase 1, reactor B phase 2 and reactor C 3 coilings in parallel mutually, reactor A phase 1 and reactor B are provided with a plurality of phase insulation 6 between 2 and between reactor B phase 2 and the reactor C phase 3 mutually, between reactor C phase 3 and the ground a plurality of insulation against ground 7 are set; Reactor A mutually 1, reactor B 23 all is provided with wiring fixing plate 4 and following wiring fixing plate 5 with reactor C mutually mutually.

Among Fig. 2, cylinder-shaped iron core 9 places among 8 coileds of reactor line bag hollow, and last wiring fixing plate 4 and following wiring fixing plate 5 respectively have 3 to make the star shelf structure, except that connection function is arranged, and the effect of constant reactance device line bag 8 in addition.

Fig. 3 is the assembling partial sectional view of core of reactor part, and the cylinder height of iron core 9 is lower than reactor line bag 8 cylinder height.

Fig. 4 is a core of reactor end face structure cutaway view, and iron core 9 is assisted to building up hollow cylinder such as the silicon steel sheet warp by much making laminated structure by high permeability material, and the inwall of hollow cylinder is fixed with insulating paper cylinder 11, and outer wall is fixed with iron core external insulation 12.

Among Fig. 5, iron core 9 is by the different silicon steel sheet interval circumferential array of width.

The effect of iron core 9 is in order to change magnetic permeability μ ₀, reduce leakage field,, guarantee reactance value.

The iron core of making according to the method described above 9 also needs can directly be used in the open air again after special safeguard procedures are handled through the moulding of overall vacuum epoxy casting, not limited by any environmental condition.The wiring arm is logical power on after, the main flux that coil produces has changed total permeability μ by iron core ₀, make magnetic permeability become big, saved the aluminum steel material, reduced the reactor bulk volume.The dry type half core reactor has solved fundamentally that the air-core reactor volume is big, floor space is big, loss is higher and the iron core reactor vibrating noise is big, use and limited to and expensive deficiency, is the substitute products of dry-type air-core reactor therefore.
