摘　　要：TRV电容器在系统标称电压高于100 kV、额定频率为50 Hz或60 Hz的电力系统中,接在母线相与地之间或者与限流电抗器并联串接于母线中,用于限制断路器上的瞬态恢复电压(TRV)和恢复电压上升率(RRRV)。文章提出了TRV电容器研制的关键技术问题和解决思路,并介绍了研制的国内外首台套750 kV超高压大容量TRV电容器的设计结构、性能指标、产品特点、电场计算、抗震验算和型式验证。可为国内TRV电容器的研制提供理论基础和宝贵的设计经验。In the power system with nominal voltage above 100 kV and rated frequency at 50 Hz or 60 Hz,TRV capacitor is connected between the busbar phase and ground or is in parallel with the current limiting reactor and connected into the busbar in series for limiting the transient recovery voltage(TRV)and the rate of rise of recovery voltage(RRRV)of the circuit breaker.In this paper,the key technical problem and solution of the TRV capacitor are proposed and the first set of 750 kV UHV and high power TRV,which is developed both at home and abroad,is introduced in the aspect of design structure,performance data,product characteristic,electric field calculation,seismic calculation and type tests.It can provide theoretical basis and valuable design experience for the development of TRV capacitor in China.
