帶有活塞裝置的高压大容量少油断路器

Gaoya dianqi, 1959
一、导言 本文将讲座对大容量断路器所提出的要求并將报导以特別有效的方式满足了这些要求的新型大容量断路器。该断路器与同一电压和断流容量的其他断路器相此,重量很輕,体积很小,它的电压范圍为6—30千伏,額定断流容量为100—600兆伏安,并经试验证明共性能良好。所以,这样的結構原理在更高电压和更大断流容量的断路器中仍可应用。 二、大容虽断路器的基本原理 大容量断路器基本上可按两种不同的原理制成,即:

考虑机械式直流断路器实际工况的IGCT器件温度分布仿真研究

Gaoya dianqi
机械式直流断路器是柔性直流电网直流故障清除的重要手段，集成门极换流晶闸管（integrated gate commutated thyristor，IGCT）是机械式直流断路器的核心元件之一。在机械式直流断路器开断过程中，IGCT器件承受振荡衰减的浪涌电流。针对IGCT器件在机械式直流断路器开断过程中的温度分布，文中首先建立机械式直流断路器电路仿真模型，获取开断过程中IGCT器件承受的电流波形，然后建立IGCT电热耦合模型，研究了实际工况下的IGCT器件温度分布特性 ...
