The invention relates to the field of rail transit, and discloses a visual grounding load switch device and system and a control method thereof. The connection state between a rear-end contact network and a front-end contact network and between the rear-end contact network and the ground in a rail transit traction power supply system is controlled by arranging a visual grounding load switch device of a disconnecting link combination circuit with an arc extinguishing function; therefore, even under the condition that the pantograph does not descend and is loaded, control over power failure and power transmission of the rear-end contact network can be achieved, and the phenomenon that an isolation knife switch is damaged by second arc discharge generated when the load is loaded is avoided through the knife switch combination circuit with the arc extinguishing function.
本申请涉及轨道交通领域,公开了一种可视化接地负荷开关装置、系统及其控制方法。通过设置由具有灭弧功能的刀闸组合电路的可视化接地负荷开关装置来控制轨道交通牵引供电系统中的后端接触网分别与前端接触网和地之间的连接状态,从而实现了即使是在受电弓未下降且带负载的情况下也可实现对后端接触网的断电和送电的控制,通过具有灭弧功能的刀闸组合电路避免了带负载时产生的拉弧二损坏隔离闸刀的现象。
