Description
技术领域 technical field
本发明涉及高压供配电装置技术领域。The invention relates to the technical field of high-voltage power supply and distribution devices.
背景技术 Background technique
目前电力电子装置普遍应用卧式晶闸管阀体机械结构，散热方式为热管散热或水冷散热(参考专利20052011875)。此类晶闸管阀体机械结构若应用于高压固态复合开关装置有三个缺陷：1.原晶闸管阀体采用卧式结构，晶闸管串长期受自身重力的影响，不利于晶闸管串的可靠压接；2.原晶闸管阀体由于阀体要长时间带电运行，因而安装了大功率的水冷或热管散热器，致使阀体成本上升，体积增加；3.原晶闸管阀体采用电压取能方式为晶闸管阀电子板供电，这种取能方式已经不满足高压固态复合开关运行工况下阀体电子板连续触发的能量需求，因而需要在晶闸管阀体中增加高频送能系统。长期以来，上述问题一直未能得以很好解决。At present, the mechanical structure of horizontal thyristor valve body is generally used in power electronic devices, and the heat dissipation method is heat pipe heat dissipation or water cooling heat dissipation (refer to patent 20052011875). If the mechanical structure of this type of thyristor valve body is applied to a high-voltage solid-state composite switchgear, there are three defects: 1. The original thyristor valve body adopts a horizontal structure, and the thyristor string is affected by its own gravity for a long time, which is not conducive to the reliable crimping of the thyristor string; 2. The original thyristor valve body needs to run with electricity for a long time, so a high-power water cooling or heat pipe radiator is installed, which increases the cost and volume of the valve body; Power supply, this energy harvesting method can no longer meet the energy demand for continuous triggering of the electronic board of the valve body under the operating condition of the high-voltage solid-state composite switch, so it is necessary to add a high-frequency energy delivery system to the thyristor valve body. For a long time, the above-mentioned problems have not been well resolved.
