Description
Technical field
The utility model relates to the accent induction device, particularly a kind of stepless accent sense reactor that is used for combined high-voltage compensation usefulness.
Background technology
The electric power industry development speed of China is very swift and violent in recent years, but still has satisfied not society's demand growing to electric power.Be the target that guarantees that the year two thousand twenty national economy quadruples again, power department prediction, be planned for the new installed capacity of the year two thousand twenty and reach 5.1 hundred million kilowatts that total installation of generating capacity reaches 1,000,000,000 kilowatts.The firepower of planning to build, hydroelectric power generation base major part concentrate on the west area of China, and power load mainly concentrates on East China, south China, just seem particularly outstanding so strengthen power grid construction.National grid alternating current-direct current UHV transmission rack basically forms four horizontal six vertical many receiving ends general layouts to the year two thousand twenty front and back, and transmission line capability reaches 25% of whole nation installation total capacity, and about 200,000,000 kilowatts, circuit always is about 30,000 kilometers, about 3,000 hundred million yuan of estimation gross investment.Under this background, the extra-high voltage electric power transformer of changing hinge as connection power supply---electrical network, electrical network---user just seems particularly important.
When the huge power transformer of ultra high voltage, reactor etc. carry out delivery test; Need the shunt compensation reactor with compensation capacitive reactive power electric current; Product capacity is big more; The corresponding compensation capacity also just needs bigger, according to the model specification of test specimen, investing method and the compensation capacity that the mode of connection is confirmed compensation reactor.
Compensation reactor occupation mode in the past does, calculates the capacity that needs compensation to different transformer test products, through the mode of manual changing-over line, obtains desired volume again.Each test, such calculating, changing-over line will carry out repeatedly repeatedly, and time-consuming taking a lot of work also causes the leading-out terminal sleeve pipe of compensation reactor to damage easily.If parameters such as the capacity of large-tonnage product are different, this moment, manually the efficiency of changing-over line just seemed very low, may influence the deadline of test mission.
Summary of the invention
The purpose of the utility model provides a kind of stepless accent sense reactor that is used for combined high-voltage compensation usefulness; It is high, the easy to use combination in any of a kind of efficient stepless have to carry transfer an induction device, be adapted to the accurate input of the compensation reactors that make an experiment such as the huge power transformer of ultra high voltage, reactor.
The purpose of the utility model realizes through following technology: the stepless accent sense reactor that is used for combined high-voltage compensation usefulness; It is characterized in that: comprise two groups of coaxial inductance coils; On two groups of coaxial inductance coil axises, be penetrated with the iron core of scalable upper-lower position, iron core is connected with motor shaft through noninductive.
In the described stepless accent sense reactor current transformer is housed.
Described stepless accent sense reactor has position detection unit.
The stepless accent sense reactor of described many groups is electrically connected with the diverter switch input, and controller is electrically connected with the control end of diverter switch, and diverter switch output is electrically connected with test specimen.
The stepless accent sense reactor of described many groups is three to five groups.
The stepless accent sense reactor of many groups connects into single group output through diverter switch, or with two groups of parallel connection outputs; Or with three groups of parallel connection outputs; Or connect output, or export with corner connection with star.
The utility model has the advantages that: owing to comprise the controller that the stepless accent sense reactor of many groups, diverter switch and control its switch are switched; The terminals of the stepless accent sense reactor of many groups are electrically connected with the diverter switch input; Controller is according to order; Switch through diverter switch and to make the stepless accent sense reactor of many groups connect into different outputs, controller reaches stepless accurate adjusting inductance value through regulating the access state between the air core inductor and running through the position of the iron core between coaxial inductance; Required inductance value is inserted in transformer, the reactor, compensate.
