Abstract
The utility model provides a fully-isolated descending wire loss type transformer, which is mainly composed of an original subsidiary side winding, high and low voltage binding posts, a box body, a radiator, and an isolated cover, wherein, a subsidiary side winding arranged on the low voltage side of the transformer is connected in parallel with a compensation condenser, and forms a whole with the transformer. The utility model has the advantages of simple structure, reasonable structure, convenient operation, etc. The utility model can reach the purpose of reactive power compensation under the condition of no substation; the utility model solves the problem of large power loss of a high-voltage electricity transmission line above the transformer, enhances power factors, reduces the power loss of the line, and saves a lot of energy.
Description
The utility model relates to a kind of transformer, especially a kind of power transformer that can improve power factor.
Because present power consumption equipment mostly is inductive load greatly, power factor is low, cause the capacity of power-supply device not to be fully used, the power loss of transmission line is bigger, caused harmful effect to electric power system, so people adopt in electric substation usually the mode of setting up the building-out capacitor cabinet in addition to improve the power factor of electric power system.Owing to separate between building-out capacitor cabinet and the transformer, need redesign and install during use, bring inconvenience to real work, especially more intense to those temporary services, operating environment is poor, build the inconvenient again place of electric substation, rethink that to improve the power factor of electric power system by the mode of setting up the building-out capacitor cabinet just more difficult, therefore the problem of electric power system reactive power compensation just is easy to be left in the basket under this condition, so just cause the electric power system power factor low inevitably, the line power loss is big, and problem such as waste energy.
The purpose of this utility model is to provide a kind of totally-enclosed line loss reducing formula transformer, so that can realize reactive power compensation comparatively easily being not easy to build under the occasion of electric substation, reach the raising power factor to the greatest extent, reduce the line power loss, the purpose of energy savings.
The purpose of this utility model is to realize like this, this totally-enclosed line loss reducing formula transformer mainly is made up of former secondary winding, high-low pressure binding post, casing, radiator and seal bootr, wherein on the secondary winding of step down side, be parallel with compensation condenser, and be integral with transformer group.
The utility model is owing to directly be connected in parallel on compensation condenser on the secondary winding of transformer, and be integral with transformer group, therefore have simple and reasonable for structure, advantage such as easy to use, even if under the situation of no electric substation, still can reach the purpose of reactive power compensation, make the big problem of the above ultra-high-tension power transmission line power loss of transformer obtain solution, improved power factor greatly, reduce the line power loss, saved a large amount of energy.
Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 2 is embodiment two circuit theory diagrams of the present utility model;
Fig. 3 is an embodiment three-circuit schematic diagram of the present utility model;
Fig. 4 is embodiment four circuit theory diagrams of the present utility model;
Fig. 5 is the utility model surface structure schematic diagram;
Fig. 6 is the A-A cutaway view of Fig. 5.
Shown in Fig. 1,2,3,4, totally-enclosed line loss reducing formula transformer of the present utility model mainly is made up of former secondary winding 1, high-low pressure binding post 4, casing 5, radiator 6 and seal bootr 3, wherein on the secondary winding of step down side, be parallel with compensation condenser 2, and be integral with transformer group.According to the mode of connection difference of the former secondary winding 1 of three-phase transformer, also can form multiple different connecting mode between the compensation condenser 2 thereon in parallel.As shown in Figure 1, the secondary winding of three-phase transformer is that star connects, and 2 of compensation condensers thereon in parallel are the triangle connection.As shown in Figure 2, the secondary winding of three-phase transformer is that triangle connects, and compensation condenser 2 thereon in parallel also connects for triangle.As shown in Figure 3, the secondary winding of three-phase transformer is that star connects, and compensation condenser 2 thereon in parallel also connects for star.As shown in Figure 4, the secondary winding of three-phase transformer is that triangle connects, and 2 of compensation condensers thereon in parallel are the star connection.More than four kinds of execution modes even be to be the situation lower link of star at the former limit of transformer winding, in addition, when the former limit of transformer winding was triangle, its secondary winding had above-mentioned four kinds of connecting modes (figure is slightly) equally, repeats no more here.
As Fig. 5, shown in 6, totally-enclosed line loss reducing formula transformer of the present utility model, its compensation condenser in parallel 2 are fixed on the casing 5 in the seal bootr 3, and are in parallel by directly being connected the mode on the low tension terminal 4 and the secondary winding of transformer.
The middle small capacity transformer that the utility model is particularly suitable for industries such as oil field, chemical industry, mine uses.
