Abstract
An online monitoring device of micro moisture in operation transformer oil is formed by an oil inlet, an oil path pipeline, an oil outlet, a sealing ring, a micro moisture sensor and a micro moisture detection unit. The oil inlet is directly connected with a transformer oil sampling valve through an oil pump. Pumped oil is contacted with the micro moisture sensor through the oil path pipeline to achieve micro moisture measurement. The oil outlet is connected with a standby valve of a transformer to achieve oil path circulation. The sealing ring ensures that the oil path pipeline is separated from external air. Signals sensed by the micro moisture sensor are transmitted to the micro moisture detection unit through a cable. The device avoids measurement error caused by an oil sample dead region caused by the fact that an oil sample does not flow when being adopted to monitor micro moisture in the transformer insulation oil online.
Description
Technical field
The utility model relates to a kind of transformer station on-Line Monitor Device, specifically is micro-moisture on-Line Monitor Device in a kind of operating transformer oil.
Background technology
Transformer oil is the inner important liquid insulating medium of transformer, plays insulation, cooling and extinguishing arc.The minor amount of water branch that exists in the transformer oil reduces the insulating property of equipment greatly, can cause major accidents such as insulation breakdown when serious.Can prevent not only that through micro-water content in the control transformer oil its dielectric strength is reduced to danger level, can also assess transformer integral insulation situation, the equipment sealing is made judgement.Therefore, micro-water content in the transformer oil is implemented on-line monitoring the safe and reliable operation of transformer equipment is had crucial meaning.
At present, the minor amount of water in the transformer insulation oil is carried out on-line monitoring usually adopt single flange to install, do not install oil circulation device additional, there is mobile or mobile insufficient phenomenon in institute's oil sample of surveying, causes the data of surveying to have error.
Summary of the invention
The purpose of the utility model provides micro-moisture on-Line Monitor Device in a kind of operating transformer oil, and it can avoid the mobile oil sample measuring error that cause in the dead band that causes of oil sample.
The utility model achieves the above object through following technical scheme: micro-moisture on-Line Monitor Device in a kind of operating transformer oil is made up of oil-in, oil line pipe, oil-out, O-ring seal, little water sensor and little water detecting unit.
Its connected mode is: oil-in is directly connected to the transformer oil sample valve through oil pump; The oil that extracts contacts with little water sensor through oil line pipe and realizes little water gaging; Oil-out is connected to the standby valve of transformer and realizes oil circulation; O-ring seal guarantees oil line pipe and outside air isolation; The signal that little water sensor is sensed arrives little water detecting unit through cable transmission.
The outstanding advantage of the utility model is:
1, guarantees the authenticity of oil sample through cycle sampling, the data difference of having avoided oil sample not flow and cause.
2, be tightly connected, guarantee that oil sample can not guaranteed not influence the primary equipment operation by air pollution.
Description of drawings
Fig. 1 is the structural representation of micro-moisture on-Line Monitor Device in the described operating transformer oil of the utility model.
Embodiment
Below through accompanying drawing and embodiment the technical scheme of the utility model is described further.
Micro-moisture on-Line Monitor Device in the described operating transformer oil of the utility model; Be made up of oil-in 1, oil line pipe 2, oil-out 3, O-ring seal 4, little water sensor 5 and little water detecting unit 6, its connected mode is: oil-in 1 is directly connected to the transformer oil sample valve through oil pump; The oil that extracts contacts with little water sensor 5 through oil line pipe 2 and realizes little water gaging; Oil-out 3 is connected to the standby valve of transformer and realizes oil circulation; O-ring seal 4 guarantees oil line pipe 2 and outside air isolation; The signal that little water sensor 5 is sensed arrives little water detecting unit 6 through cable transmission.
The operation steps of micro-moisture on-Line Monitor Device is in the described operating transformer oil:
1, sample valve extracts oil sample through oil pump and gets into oil-in 1;
2, oil sample gets into oil line pipe 2, contacts with little water sensor 5;
3, under the promotion of oil pump, return the standby valve of transformer from oil-out 3;
4,5 pairs of oil samples of little water sensor detect, and data are imported little water detecting unit 6 into, carry out the statistical computation of micro-water content in the oil.
