Description
The utility model is the thyristor valve circuit that is applied in the high voltage static type dynamic reactive power compensation equipment.
Thyristor is a kind of high power semiconductor component, it has advantages such as volume is little, in light weight, efficient is high, the life-span is long, working service is convenient, but thyristor bears the ability of overvoltage and overcurrent, and for high voltage static type dynamic reactive power compensation equipment, the rated voltage of single thyristor has been far smaller than actual requirement.
The purpose of this utility model is to address the above problem and thyristor valve circuit in the high voltage static type that the is applied to dynamic reactive power compensation equipment that provides.
The technical solution of the utility model is as follows:
Be applied to the thyristor valve circuit in the high voltage static type dynamic reactive power compensation equipment, it is characterized in that: per two thyristor inverse parallels, two branch roads in parallel at the antiparallel two ends of each thyristor: one is resistance branch, another is the series arm of an electric capacity and two resistance, form thyristor inverse parallel unit, several units in series are formed thyristor inverse parallel assembly, assembly is composed in series thyristor valve again, directly insert electrical network through Controlled Reactor.
The utility model uses the thyristor series connection of same model, and the rated voltage that has solved single thyristor with the thyristor inverse parallel, makes it in the complete period conducting less than the problem that reality requires.For the voltage that makes each thyristor approaching mutually, to each thyristor grading resistor in parallel.In order to make the voltage distribution in the switching process even, to the thyristor parallel connection electric capacity.For preventing thyristor conducting moment, discharge causes excessive di/dt to electric capacity to thyristor, and series resistance R forms resistance capacitance series arm, i.e. resistance-capacitance protection device in capacitive branch.
Fig. 1 is the utility model high voltage static type dynamic reactive power compensation equipment thyristor valve circuit diagram.
Embodiment:
See Fig. 1, per two thyristor T1, T2; T3, T4; T5, T6; T7, T8; T9, T10; T11, T12; T13, T14; T15, T16; T17, T18; T19, T20 inverse parallel, two branch roads in parallel at the antiparallel two ends of each thyristor: one is resistance branch R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, and another is series arm 4C1,4R1, the 4R2 of an electric capacity and two resistance; 4C2,4R3,4R4 4C3,4R5,4R6; 4C4,4R7,4R8,4C5,4R9,4R10; 4C6,4R11,4R12; 4C7,4R13,4R14; 4C8,4R15,4R16; 4C9,4R17,4R18; 4C9,4R19,4R20 form thyristor inverse parallel unit, and several units in series are formed thyristor inverse parallel assembly, and assembly is composed in series thyristor valve again, directly insert electrical network through Controlled Reactor.
The required thyristor quantity of each thyristor valve is decided by the rated voltage and the thyristor voltage parameter of high voltage static type dynamic reactive power compensation equipment.
