The utility model relates to the field of ultra-high voltage electrical manufacturing, in particular to a star frame for a dry-type air-core reactor, which includes a plurality of support plates and a central sleeve made of stainless steel, and the support plates are arranged along the center The circumference of the sleeve is fixed vertically, and the upper surface of the support plate is provided with several slots along the length direction, and the support plate is provided with fixing holes. Since the dry-type air-core reactor star frame made by the utility model is made of stainless steel, while satisfying the flow-through ability, the seismic strength is increased. After testing, the seismic fortification intensity of the reactor made by the utility model has changed from the original 8 The temperature increased to 9 degrees. It ensures the safety when used in ultra-high voltage and ultra-high voltage power grids. The electrical conductivity of stainless steel is only 1/26 of that of aluminum, so the eddy current loss of the star frame can be greatly reduced. After testing, the star frame of the utility model can reduce the eddy current loss by more than 50% compared with the star frame made of ordinary aluminum material in the reactor operation test.
Description
Technical field
The utility model relates to super, ultra high voltage Electric Manufacture field, particularly relates to a kind of dry-type air-core reactor starframe.
Background technology
In superhigh pressure and extra-high voltage electric transmission and transformation engineering, dry-type air-core reactor is except must tolerating high voltage and very large electric current, the shock resistance that also Ying Yaoyou is higher, also to reduce the loss of electric energy simultaneously, therefore the strength character of dry-type air-core reactor support and low loss performance particularly important.
What conventional stent used is all pure aluminum material, this is because support needs caused by logical big current.But aluminium is very soft, intensity is very poor, and the starframe anti-seismic performance made like this is not fine, when there being very large short circuit current to flow through or occur resonance, under the effect of enormous power, the structural member of reactor is possibly by shake dislocation, and this consequence is very serious.And in order to proof strength, the size of the starframe of traditional fine aluminium can be done very large, causes loss also very large.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, and provides a kind of dry-type air-core reactor starframe, has good support strength and anti-seismic performance, reduces the wastage.
The utility model for achieving the above object, by the following technical solutions: a kind of dry-type air-core reactor starframe, it is characterized in that: comprise several support plates and cylindrical central sleeve of being made up of stainless steel, described support plate is fixed along the ring Zhou Chuizhi of described cylindrical central sleeve, the upper surface of described support plate is provided with several draw-in grooves along its length, and described support plate is provided with fixing hole.
Preferably, described fixing hole is provided with U-shaped block.Booster action is hung during for rising.
The beneficial effects of the utility model are: the dry air core reactor star frame made due to the utility model is that stainless steel makes, while meeting through-flow ability, add shock strength, after tested, the reactor seismic fortification intensity that the present invention makes has brought up to 9 degree from original 8 degree.Ensure that for safety when superhigh pressure and extra-high voltage grid.Stainless conductivity only has 1/26 of aluminium, therefore can greatly reduce the eddy current loss of starframe.After tested, starframe of the present invention, in reactor operation test, can reduce eddy current loss more than 50% compared with the starframe made with common aluminium.Improve performance, along with the application of this product, significantly can reduce the construction cost of China's electrical network, be conducive to the fast development of national economy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment, as shown in Figure 1, a kind of dry-type air-core reactor starframe, comprise several support plates 1 and cylindrical central sleeve 2 of being made up of stainless steel, described support plate is fixed along the ring Zhou Chuizhi of described cylindrical central sleeve, the upper surface of described support plate is provided with along its length several draw-in grooves 3, colligation epoxy impregnation glass fibre reinforcing band use, for strengthening the anti-electrodynamic action in horizontal and vertical direction.Described support plate is provided with fixing hole 4, for fixing with rain cover.Described fixing hole is provided with U-shaped block 5.
The dry air core reactor star frame made due to the utility model is that stainless steel makes, and while meeting through-flow ability, add shock strength, after tested, the reactor seismic fortification intensity that the present invention makes has brought up to 9 degree from original 8 degree.Ensure that for safety when superhigh pressure and extra-high voltage grid.Stainless conductivity only has 1/26 of aluminium, therefore can greatly reduce the eddy current loss of starframe.After tested, starframe of the present invention, in reactor operation test, can reduce eddy current loss more than 50% compared with the starframe made with common aluminium.Improve performance, along with the application of this product, significantly can reduce the construction cost of China's electrical network, be conducive to the fast development of national economy.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
