Abstract
The utility model relates to a low-voltage series reactor which is used for a power distribution system. An iron core of the low-voltage series reactor is reasonably divided into segments; the segments are like the Chinese character ' shan ' and the reverse Chinese character ' shan '; a pie type iron core and a gap for the installation of an air gap pad are arranged between the segments; the segments are assembled together with three coils, via connection parts; a dry type self-cooled wind channel is arranged in the coils. The low-voltage series reactor can eliminate higher-order harmonics at low-voltage side. The utility model has the advantages of simple structure, easy fabrication and less investment, and can be widely popularized and applied in big, middle and small type enterprises.
Description
The utility model belongs to a kind of low pressure series reactor of using in the electric power system.
In electric power system, because the concentrated use of a large amount of silicon controlled rectifiers, adjust pilot angle because of controllable silicon electrical network is caused high order harmonic component and serious wave distortion, cause the capacitor box that is used for reactive power compensation normally not come into operation, cause power factor low, aggravated the situation of supply of electric power deficiency.The high-pressure series reactor that present transformer stations at different levels use uses with normal though can guarantee the input of high-voltage capacitance cabinet, because manufacturing process complexity, difficulty are big, investment is not suitable for promoting the use of with electric unit more.
The purpose of this utility model provides a kind of in low-pressure side elimination high order harmonic component, and easy to manufacture, invests little low pressure series reactor.
The utility model will be described with reference to the accompanying drawings implementation and embodiment.
Accompanying drawing 1 is looked schematic diagram for master of the present utility model.
Accompanying drawing 2 is looked schematic diagram for a left side of the present utility model.
Accompanying drawing 3 is an iron core schematic diagram of the present utility model.
Accompanying drawing 4 is a coil sectional schematic diagram of the present utility model.
The iron core 12 reasonable sections of being, go to upper and lower " mountain " font, the centre is provided with cake formula iron core 14, and leave the gap 13 of installing insulating air gap pad, " mountain " font iron core 12 and three coils 9 fit together in the mode of being rigidly connected, with the pull bar 2 of double threaded screw, upper bridge steel 10 and 8 vertical fastening effects of collet, drift bolt 7, upper and lower folder 4,6 horizontal fastening effects, upper and lower folder 4,6 and coil 9 between add and press enclosed mass 5, the lead-in wire 11 of coil 9 Be connected on the binding post 3 of terminal plate 1, terminal plate 1 is fixed on the pull bar 2 by support 17, is provided with the air channel 15 that is made of insulation strip 16 supports in the coil 9, to reach the self cooling purpose of dry type.
The utility model is simple in structure, technology is easily grasped, small investment, and high efficiency can be in large, medium and small enterprise wide popularization and application.
The utility model is satisfactory in the result of medium-sized factory trial run.Do not use before the utility model, the transformer that this factory is 1600 kilovolt-amperes is only used about 1000 kilovolt-amperes, just sends overload-alarm as increasing again, even breaking, and because power factor is low, and power supply administration every month overcharges ten thousand yuan of electricity charge 3.2-6 to this factory.Once considered to adopt the high-pressure series reactor, and invested hundreds thousand of units because of need and fail to embark on journey.Adopted the utility model to be directly used in original capacitor box afterwards, when full station service peak, power factor rises to 0.87 by original 0.75, the current value of (10,000 volts) also by original 110A, is reduced to 75A in the high-pressure side, calculate like this, full factory can economize on electricity and spend 10,000 more every day, and one month can be from cost-recovering in the electricity charge, and its indirect benefit is also very big.So employing the utility model not only can be saved a large number of electricity charge, and provides the electric power assurance for expanding production capacity.
