六脉波融冰整流器直流电压输出机构Six-pulse ice-melting rectifier DC voltage output mechanism

技术领域technical field

本发明属于电气工程技术领域，涉及一种六脉波融冰整流器直流电压输出机构，尤其适用于高压大功率六脉波融冰整流器。The invention belongs to the technical field of electrical engineering, and relates to a DC voltage output mechanism of a six-pulse ice-melting rectifier, especially suitable for high-voltage and high-power six-pulse ice-melting rectifiers.

背景技术Background technique

我国南方冰雪灾害频发，易给电网输电线路带来严重损害。对覆冰线路进行电流融冰是电网应对冰冻灾害最直接、最有效、最安全、最经济的重要手段之一。采用直流融冰，输电线路上电抗分量将不起作用，加上同样大小的融冰电流，采用直流融冰所施加的电压比交流融冰小得多，大大提高了融冰过程的安全性和经济性。直流融冰在国内输电线路覆冰抗冰中得到了广泛的运用。而直流融冰装置最重要的部分为整流器，用以实现融冰电源交流向直流的转变，为覆冰线路提供有效的直流融冰电流。六脉波融冰整流器的变流部分结构简单，在融冰整流器中得到较多运用。但由于输入、输出电压高，输出直流电流大，融冰功率大，融冰整流器内结构设计与器件绝缘设计是高压大功率融冰整流器生产的重点与难点。传统的六脉波融冰整流器，均是通过绝缘板等绝缘材料对高压变流部分实现绝缘，由于功率器件较多，且有众多输入输出连接铜排要进行绝缘设计，因此需要用绝缘材料做成大量各种形状的绝缘件，借以对融冰整流器内的功率器件、连接铜排等实现绝缘。由此，其所造成的整流器内部结构复杂且装配困难。为简化六脉波融冰整流器结构，如何对融冰整流器内带电部件实现有效绝缘与结构设计成为了一项亟待解决的问题。Ice and snow disasters occur frequently in southern my country, which can easily cause serious damage to power grid transmission lines. Current melting of ice-covered lines is one of the most direct, most effective, safest and most economical means for power grids to deal with freezing disasters. With DC ice melting, the reactance component on the transmission line will not work, and with the same size of ice melting current, the voltage applied by DC ice melting is much smaller than that of AC ice melting, which greatly improves the safety and security of the ice melting process. economy. DC icing has been widely used in domestic transmission line icing anti-icing. The most important part of the DC ice-melting device is the rectifier, which is used to realize the transformation of the ice-melting power supply from AC to DC, and provide effective DC ice-melting current for the ice-coated line. The structure of the variable flow part of the six-pulse ice-melting rectifier is simple, and it is widely used in the ice-melting rectifier. However, due to high input and output voltages, large output DC current, and high ice-melting power, the internal structure design and device insulation design of the ice-melting rectifier are the key points and difficulties in the production of high-voltage and high-power ice-melting rectifiers. The traditional six-pulse ice-melting rectifier uses insulating materials such as insulating plates to insulate the high-voltage converter part. Since there are many power devices and there are many input and output connection copper bars that need to be insulated, it is necessary to use insulating materials. A large number of insulating parts of various shapes are formed to insulate the power devices and connecting copper bars in the ice-melting rectifier. Therefore, the internal structure of the resulting rectifier is complex and difficult to assemble. In order to simplify the structure of the six-pulse ice-melting rectifier, how to effectively insulate and design the live parts in the ice-melting rectifier has become an urgent problem to be solved.
