Description
Technical field
The invention belongs to filtering components and parts field, be specifically related to a kind of split type parallel single-phase direct current reactor.
Background technology
The reactor taked in power system common are current-limiting reactor and shunt reactor.Current-limiting reactor is mainly used to limiting short-circuit current, also have in wave filter with the capacitor serial or parallel connection higher hamonic wave for limiting in electrical network, the expansion of net capacity so that the rated value of system short circuit capacity increases rapidly.Such as the low pressure 35kV side in 500kV electric substation, maximum three-phase symmetrical short circuit current virtual value is already close to 50kA.
In order to limit the short circuit current of transmission line of electricity, protecting power equipment, it is necessary to install reactor, reactor can reduce short circuit current and make the voltage of transcient short circuit time system remain unchanged.Installing damping reactor (i.e. current-limiting reactor) in capacitor loops, capacitor loops acts the effect suppressing to shove when putting into.Form harmonic wave loop together with Capacitor banks simultaneously, play the filter action of each harmonic.As in the capacitor loops of 500kV electric substation 35kV reactive power compensator, in order to limit shoving and suppressing the higher hamonic wave of power system when putting into capacitor, 35kV capacitor loops must be installed damping reactor, when suppressing 3 subharmonic, adopt rated voltage 35kV, inductance ratings amount 26.2mH, the single-phase outdoor type damping reactor of rated current 350A dry-type hollow, 3 subharmonic are formed resonant tank, i.e. 3 subharmonic filter circuit with 2.52Mvar capacitor by it.Equally, in order to suppress 5 times and above higher hamonic wave, have employed the single-phase outdoor type damping reactor of rated voltage 35kV, inductance ratings amount 9.2mH, rated current 382A, 5 times and above higher hamonic wave are formed resonant tank with 2.52Mvar capacitor by it.Serving the effect suppressing higher hamonic wave, it is necessary to explanation, in national standard " reactor " GB10229 88 and IEC289 88 international standard, all use and technical conditions to damping reactor dictates.But damping reactor is called current-limiting reactor by some department domestic at present, is inappropriate strictly, because above-mentioned standard does not all have this title of current-limiting reactor；And common E type reactor volume is big, energy consumption is high, leakage field, electromagnetism interference poor performance etc., it is impossible to meet the electrical property in physical device and volume requirement.
Accordingly, it is desirable to provide a kind of parallel single-phase direct current reactor avoids the generation of drawbacks described above.
