The invention provides a high-voltage transformer fire extinguishing method and fire extinguishing device.The fire extinguishing method is based on the high-voltage transformer fire extinguishing device.The fire extinguishing method comprises the steps that preparation work before fire extinguishing is conducted, specifically, fire area checking and fire extinguishing device preparation are conducted; according to the planned different throwing points, the multiple fire extinguishing devices face the throwing points to which the fire extinguishing devices belong, fire extinguishing bombs are thrown one by one, and fire extinguishing operation is started; after single-time fire extinguishing operation of the fire extinguishing device is completed, returning and landing according to a preset route; an observation unmanned aerial vehicle is arranged, and according to collection information of the observation unmanned aerial vehicle, if the fire extinguishing target is not reached, the fire extinguishing device starts fire extinguishing operation again until the fire extinguishing target is completed; and checking and improving after the fire extinguishing target is completed. Through joint operation of the unmanned aerial vehicle body, the fire behavior of a power transmission line area can be controlled, the fire extinguishing purpose is achieved, people are replaced to make close contact with a fire source and electrified equipment, and potential safety hazards of human injuries are avoided.

本发明提供了一种高压变压器的灭火方法和灭火装置，该灭火方法基于高压变压器的灭火装置，该灭火方法包括：灭火前准备工作，包括起火区域核对和灭火装置准备；根据规划的不同的投放点位，多个灭火装置朝向其所属的投放点位，逐个投放灭火弹，开启灭火作业；灭火装置单次灭火作业完成后，按照预设航线返回降落；设置观察无人机，根据观察无人机的采集信息，如果未达到灭火目标，则灭火装置重新开启灭火作业，直至完成灭火目标；灭火目标完成后的检查和改进。通过无人机本体共同作业，能够控制输电线路区域火势，同时实现灭火目的，替代人员近距离接触火源和带电设备，避免造成人身事故安全隐患。
