The invention relates to a live-line automatic neutral section passing system based on an electronic switch switching voltage phase shift mode. The live-line automatic neutral section passing system comprises a plurality of electronic switches, one or two transformers and a control unit, wherein each electronic switch is composed of a plurality of semiconductor switch valves, and a secondary winding of each transformer is provided with a plurality of center taps or is not provided with a center tap. According to the electrified automatic neutral section passing system based on the electronic switch switching voltage phase shift mode, phasor superposition is carried out on alternating-current voltages of different phases and different amplitudes through the electronic switch and the transformer to obtain an intermediate phase shift transition voltage; therefore, the neutral area overhead line system voltage is transited from one phase of power supply arm voltage to the other phase of power supply arm voltage through the intermediate phase-shifting transition voltage in a gradual phase-shifting manner, so that the influence of the power distribution phase on train operation is eliminated. The invention provides a new solution thought for solving the neutral section passing problem of the alternating current electrified railway train.
本发明涉及基于电子开关切换电压移相方式的带电自动过分相系统,包括多个由若干个半导体开关阀构成的电子开关、一个或两个副边绕组带若干个中间抽头或不带中间抽头的变压器以及控制单元。基于电子开关切换电压移相方式的带电自动过分相系统利用电子开关和变压器合把不同相位和不同幅值的交流电压进行相量叠加获得中间移相过渡电压,从而实现中性区接触网电压从一相供电臂电压经由中间移相过渡电压逐步移相过渡到另一相供电臂电压,以消除电分相对列车运行的影响。本发明为解决交流电气化铁路列车过分相问题提供了新的解决思路。
