A transformer oil gas detection device

Abstract

The invention relates to a transformer oil-gas detection device, which comprises a transformer, wherein a valve A and a valve B are arranged on the side wall of the transformer, one side of the valve A is communicated with an insulating oil inner cavity of the transformer, and the other side of the valve A is sequentially communicated with a one-way valve B, a sampling device, a filtering device, a cooling device, an oil pump, an oil pressure detector, and an oil-gas separation device; one side of the valve B is communicated with an insulating oil inner cavity of the transformer, and the other side of the valve B is sequentially communicated with a one-way valve A, an exhaust device and an oil-gas separation device; a gas outlet of the oil-gas separation device is sequentially communicated with a gas pump and a gas storage chamber, and a sampling gas outlet of the gas storage chamber is communicated with a chromatographic column; one side of the chromatographic column is communicated with a thermal conductivity cell detector, and the other side of the chromatographic column is communicated with the gas storage chamber; and a control board is electrically connected with the oil pump, the oil pressure detector, the gas pump and the thermal conductivity cell detector. The transformer oil-gas detection device has the advantages of being automatic in monitoring, high in safety, long in service life, low in cost, high in detection precision, and reliable in performance.

Description

technical field

[0001] The invention belongs to the field of transformer oil gas detection, and in particular relates to a transformer oil gas detection device. Background technique

[0002] With the development of economy and society, the oil and gas online detection of transformers currently used is very critical. This is because the insulation performance of transformers is a necessary condition for substation work. Carbon dioxide generated by physical and chemical reactions of insulating oil due to arcs, high temperatures, etc. , water vapor, hydrogen alkane gas, etc., cause the insulation cavity in the transformer to expand, and the insulation performance is affected. If the gas accumulates too much, it will inevitably lead to a decline in the insulation performance of the transformer, and there is a hidden danger of causing a major accident. Therefore, it is necessary to develop a A device that automatically monitors the gas content in the transformer at an early stage...
