Description
Technical field
This utility model belongs to transformer technology field, is specifically related to a kind of energy-saving stereo rewinding material combined transformer.
Background technology
In the construction of conservation-minded society of China, along with the deepening continuously of construction and upgrading of the development of electric utility and city rural power grid, vast power consumer is more and more higher to the requirement of energy saving transformer.But, the competition between Transformer Manufacturing Enterprises is the most more and more fierce, economizes on resources and is increasingly becoming the most important thing of enterprise.First combined transformer is developed by u s company, is complete distribution equipment transformator, the on-load switch of high powered part and protection device, low-voltage distribution equipment, low-temperature measurement system and reactive power compensator combined.Combined transformer is owing to using hermetically sealed, all insulation structure, and compact conformation is simple, without power distribution room, can be rest directly upon indoor or outdoors, and volume ratio tradition box-type substation (European-type box change) is little, is the most extensively received by the market.
Distribution transformer is one of capital equipment of distribution network system, and iron core is then the inner skeleton of transformator, because it is the medium of electric energy conversion.In order to accelerate the update of product, improving energy-saving horizontal, meet the demand in market, transformer production enterprise in all parts of the country all increases the dynamics producing energy-economic transformer core construction, researching and developing.Along with the energy-conservation appearance than transformator of all kinds, observing from core construction, the transformator of three-dimensional rolled iron core structure has relatively low open circuit loss index and is increasingly welcome by user.Therefore, it is necessary to its core construction optimization is designed, so that it is determined that to the energy-saving effect of this transformator and application prospect.
Traditional iron core is spliced by two frames, and each frame is divided into two parts by middle oil duct again, every part individual volume around, by special tooling device split after having annealed, and place oil duct.Although this knot only has stem half because of Double layer iron, can effectively control shipping height；Double mount structure ferrum outer contour surfaces are planes, and cross-over block, briquette structure are simple.Four piece piece difficulty unshakable in one's determination are big；Coil height is higher, adds overhang insulation, straight line portion unshakable in one's determination oneself more than 2 meters, during winding, linearity is poor, affects coil winding；Traction, feed winding need to cut-off staggered coiling, upper and lower winding Intermediate Gray clearance for insulation, and ampere-turn is uneven；High-tension coil is very big to other post insulation distance (i.e. 220kV is over the ground), and materials unshakable in one's determination increase, and other post needs shielding；Because Double layer iron blocks, low-voltage coil inner bracing strip places difficulty, and interior loop support not yet in effect, anti-short circuit capability is more weak.
Utility model content
The purpose of this utility model is to provide a kind of energy-saving stereo rewinding material combined transformer, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of energy-saving stereo rewinding material combined transformer, including altitude chamber, operation with high pressure room and low-pressure chamber, described operation with high pressure room is arranged on the right side of altitude chamber, the inside of described operation with high pressure room is provided with transformer room, described low-pressure chamber is arranged on the lower end of operation with high pressure room, the inside of described low-pressure chamber is provided with low-voltage cabinet, the left side of described low-pressure chamber is provided with three dimensional wound core transformator, the inside of described three dimensional wound core transformator is provided with transformer core, described transformer core includes single frame formula rewinding material, described single frame formula rewinding material is spliced by the half-core of two independent windings, and the centre of single frame formula rewinding material is placed with oil duct, the outside of described single frame formula rewinding material is provided with winding.
Preferably, it is provided with fuse and bushing in described altitude chamber.
Technique effect of the present utility model and advantage: this energy-saving stereo rewinding material combined transformer, fuse is placed in operation with high pressure room by it, cancels Fuse box, simplifies and makes, saves substantial amounts of transformer oil；The high-tension coil of winding can use two parts series connection or two parts to be connected in parallel on transformer fe in the heart；If two parts are connected, during shock wave incoming wave, one high pressure first and last end gradient is the biggest, insulation distance needs to amplify, and connect pars intermedia and there is electric capacity catastrophe point, voltage pulsation is unfavorable to insulation very greatly, therefore this utility model takes two parts parallel-connection structure, therefore, the alternate isoelectric level of high-voltage parallel or the least potential difference, stay enough mechanical distance and necessary coiling nargin, low pressure inner bracing strip secure support, anti-short circuit capability is strong, coil distribution is on two posts, thermal source disperses, it is more conducive to heat radiation, consider single frame formula iron core high-voltage parallel structure at anti-short circuit capability, insulating reliability aspect has more advantage, therefore this utility model energy-saving stereo rewinding material combined transformer uses single-phase single frame formula core construction；Therefore, this utility model is reasonable in design, simple in construction, it is possible to increase anti-short circuit capability and have the advantages such as high-strength insulation.
