Abstract
The utility model discloses an oil channel circulation system of chromatographic high-performance overall analysis online monitoring device, which comprises pipelines, solenoid valves, a cylinder and a vacuum pump. The oil inlet of the cylinder is communicated with the upper oil outlet end and the lower oil outlet end of a transformer through two pipelines, the vacuum pump is communicated with the gas inlet end of the cylinder through a pipeline, the gas inlet end of the cylinder is also communicated with a carrier gas channel system through a pipeline, and each pipeline is provided with a solenoid valve. The utility model has the advantages that: since the oil channel circulation system consists of the cylinder and the vacuum pump, the circulation and can realized once a minute, the frequency of cleaning circulation can be calculated according to the volume of the oil feeding pipeline, the dead oil in the pipeline can be cleaned within minutes, the circulation structure is simpler and the circulation is faster and more efficient compared with the traditional external circulation pump, and without the circulation pump, the cost can be saved, and various faults caused by the circulation pump can be prevented. The whole monitoring device has the advantages of compact structure and low cost.
Description
Technical field
The utility model relates to the chromatogram monitoring device, particularly a kind of oil circulation system that is applicable to the insulating oil chromatogram monitoring device of transformer.
Background technology
The stratographic analysis of insulation oil dissolved gas is to detect the effective ways that oil-filled inside electric appliance has the latency fault, and along with carrying out of electrical equipment repair based on condition of component work, the stratographic analysis of insulating oil seems more important, and testing will be heavier.Because laboratory off-line chromatogram sense cycle is longer, therefore national in recent years each province and city power department has all been carried out on-line monitoring, for active and effective effect has been played in the safe operation of electrical network main equipment.Oil circulation system to being used for the chromatogram monitoring device of high-power transformer so far both at home and abroad mostly adopts circulating oil path and ebullator.Promptly go up and be trapped in ducted oil after once using owing in the pipeline of the oil piping system of measurement mechanism, exist dead oil one all the time,, influenced the detection quality with regard to caused the phenomenon of sneaking into dead oil when detecting next time.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art and a kind of oil circulation system that detects quality, avoids sneaking into the chromatogram high-performance total analysis on-Line Monitor Device of dead oil next time in detecting that improves is provided.
The purpose of this utility model realizes by following approach.
A kind of oil circulation system of chromatogram high-performance total analysis on-Line Monitor Device, described oil circulation system comprises pipeline, solenoid valve, its structural feature is: also include cylinder and vacuum pump, the logical hydraulic fluid port of cylinder is connected by oil-out end about two pipelines and the transformer, described vacuum pump is connected with the blow vent end of cylinder by pipeline, the blow vent end of cylinder also is connected with the carrier gas air-channel system by pipeline, and each pipeline is provided with solenoid valve.
In use, two pipelines and solenoid valve are connected the end of oil-out up and down of transformer and the logical hydraulic fluid port of cylinder respectively, utilize the cylinder in the oil circulation system, stainless-steel tube by connecting V2 and transformer is among the transformer oil suction cylinder space A, by the stainless-steel tube that connects V4 and transformer the transformer oil among the cylinder space A is returned in the transformer again, carry out this operation and once be the circulation primary oil sample, can estimate the volume of V2 to transformer coupling part stainless-steel tube, thereby calculate the dead oil in the complete pipe blow-through of the ability that to circulate several times, the number of times that how much comes Control Circulation of volume.It is quantitative just to carry out oil sample after circulation is good, more fixed measured oil sample is sent into follow-up degas chamber and outgases and handle etc.This oil circulation system, per minute is once capable of circulation, according to in-line volume calculation clean cycle number of times, the dead oil that just can finish pipeline in several minutes cleans, simpler compared with the external ebullator loop structure of traditional usefulness, circulation has more been saved ebullator simultaneously with effective and rapid, not only saved cost, and avoided because of the caused various faults of ebullator.
The logical hydraulic fluid port of cylinder also is conducted by pipeline and vacuum pump, and pipeline is provided with solenoid valve.
The logical hydraulic fluid port of cylinder is connected vacuum pump, and solenoid valve is set on pipeline, by control electromagnetic valve, utilize vacuum pump just can realize that the cavity A of countercylinder cleans like this.
Described pipeline is a stainless-steel tube.
In sum, the utility model has following advantage compared to existing technology:
The utility model adopts cylinder and vacuum pump to constitute the oil circulation system, per minute is once capable of circulation, according to in-line volume calculation clean cycle number of times, the dead oil that just can finish pipeline in several minutes cleans, simpler compared with the external ebullator loop structure of traditional usefulness, circulation has more been saved ebullator simultaneously with effective and rapid, not only saved cost, and avoided because of the caused various faults of ebullator.Whole monitoring device compact conformation, the characteristics that price is low.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment
Embodiment
Below in conjunction with embodiment the utility model is described in more detail.
Most preferred embodiment: a kind of oil circulation system of chromatogram high-performance total analysis on-Line Monitor Device as shown in Figure 1.Comprise cylinder 1, vacuum pump 2, pipeline 3, various multiple-pass joint and solenoid valve V, carrier gas air-channel system 4.
V2 and V4 are connected to the end of oil-out up and down of transformer with Φ 3 stainless-steel tubes,, open V2, V10 in order to clean the dead oil in this stainless-steel tube.Allow transformer oil enter among the space A of cylinder by stainless steel circulation pipe 1, close V2 again, V10, open V16, V4, cylinder piston rod is moved downward, make the oil among the A of space come back in the transformer, for playing the abundant circulation of oil circuit, can estimate the volume of V2 to transformer coupling part stainless-steel tube, thereby calculate the dead oil in the complete pipe blow-through of the ability that to circulate several times, after cleaning is finished, open V2, V10 allows oil sample enter to carry out among the cylinder space A oil sample quantitative, the oil after the degassing is handled again the stainless-steel tube by connecting V4 and transformer in the return of the transformer oil among the cylinder space A transformer.
It is same as the prior art that present embodiment is not stated part.
