Fire hazard oil drainage system for lubricating oil tank of gas turbine generator set

The invention provides a gas turbine generator set lubricating oil tank fire hazard oil drainage system which comprises a control loop A, a control loop B and a control loop C. Each control loop comprises a 220V alternating current control power source, a manual oil drainage button, a two-channel relay and two electric valve actuators. The two-channel relay coil is electrified to drive two pairs of relay contacts to be closed, after the relay contacts are closed, the two electrically operated valve actuators are electrified to act, and after the electrically operated valve actuators act, the two electrically operated valves are driven to be opened; the three sets of electric valves are connected in a staggered and crossed combination mode. The oil drain valve of the lubricating oil tank can be remotely controlled in a control room through the button, and the device has the advantages of being rapid in operation, safe and reliable. 本发明提供一种燃气轮机发电机组润滑油箱火灾泄油系统，包括在A、B、C三组控制回路，每组控制回路包括220V交流控制电源、手动放油按钮、双通道继电器和两个电动阀
