Abstract

The invention relates to a power oil discharge device of an extra-high voltage converter transformer, a control system and a control method and belongs to the technical field of the oil discharge of extra-high voltage converter transformers. The power oil discharge device comprise a body tee joint, a stop valve, a body oil tank oil discharge device, an oil conservator oil discharge device and an accident oil pool; the body tee joint is arranged between the upper part of the body oil tank and the bottom of an oil conservator; the first port of the body tee joint is connected with the bottom ofthe oil conservator through a pipeline; the second port of the body tee joint is connected with the oil conservator oil discharge device through a pipeline; the third port of the body tee joint is provided with the stop valve; the output port of the stop valve is connected with the body oil tank through the pipeline; the body oil tank oil discharge device is connected to the bottom of the body oiltank through a pipeline; the output ends of the body oil tank oil discharge device and the oil conservator oil discharge device are respectively connected with the accident oil pool through pipelines; and the body oil tank oil discharge device comprises an oil pump connected with the body oil tank through a pipeline. When an initial fire occurs, a large amount of transformer oil in the body oil tank and the oil conservator can be discharged quickly, safely and reliably.

Description

technical field [0001] The invention belongs to the technical field of UHV converter oil discharge technology, and in particular relates to an UHV converter converter power oil discharge device, a control system and a method. Background technique [0002] UHV refers to the voltage level of AC 1000 kV and above and DC plus or minus 800 kV and above. The main characteristics of UHV transmission are high voltage, large transmission capacity, and narrow line corridors, which are suitable for high-power and long-distance power transmission. [0003] The converter station is a system for mutual energy conversion between DC and AC in UHV transmission projects. In addition to the same equipment as the AC substation, such as the AC field, the converter station also has the following equipment: converters, converter transformers, AC and DC Filters and reactive power compensation equipment, smoothing reactors, etc. [0004] The converter transformer is a crucial key equipment in the U...
