Problems solved by technology

However, after the UHV converter discharges high-temperature oil, there is still high-temperature oil gas and insulating materials inside the fuel tank, which is very likely to re-ignition after contact with air, and there are still very large safety hazards

Abstract

The invention discloses an extra-high voltage converter transformer emergency oil discharge and fire-fighting medium injection device, a method and a system. Oil discharge pipelines of a body and an oil conservator are both provided with a control valve and a flow meter, and independent control over the oil discharging speed of the two pipelines can be achieved. Similarly, the fire-fighting mediuminjection speed of the body and the oil conservator can also be independently controlled, the oil discharging amount is matched with the medium injection amount, the vacancy after the oil level is lowered is filled in time, fire disasters are prevented from entering a converter transformer body, and the fire scale expansion risk is reduced. Meanwhile, cavities are prevented from appearing in thebody and the oil conservator, internal high-heat oil gas and insulating materials are cooled, re-combustion potential safety hazards are reduced, safety guarantee and rescue favorable conditions are provided for rescuers, and the fire-fighting capacity of the converter transformer is improved.

Description

technical field [0001] The invention relates to the technical field of fire protection for UHV converter stations, in particular to an emergency oil discharge and fire-fighting medium injection device, method and system for UHV converter stations. Background technique [0002] In recent years, with the continuous improvement of the voltage level of HVDC transmission, the number and capacity of power equipment in the DC converter station have continued to increase, and the risk of fire protection has also increased. The converter transformer is the core primary equipment of the converter station, which contains a large amount of insulating oil, and the risk of fire is extremely high. The single-phase oil weight of the 1100kV low-end converter transformer is about 166 tons, and the single-phase oil weight of the 1100kV high-end converter transformer reaches About 285 tons, the insulating oil used has a flash point of 135-150°C, an ignition point of 165-195°C, and a spontaneous...
