The sampling device is connected with the cable terminal, and comprises a vacuum pump, a first vacuum line, a second vacuum line, a surge flask, an oil sampling pipeline and an insulating oil storage bottle, wherein the vacuum pump is connected with the surge flask through the first vacuum line; the surge flask is connected with the insulating oil storage bottle through the second vacuum line; and the insulating oil storage bottle is connected with the cable terminal through the oil sampling pipeline. Compared with the prior art, the sampling device for the insulating oil of the cable terminal has the advantages of wide application range, high safety, high accuracy and the like.
Description
Technical field
The present invention relates to a kind of sampler of oil product, especially relate to a kind of sampler of cable terminal insulation oil.
Background technology
Cable termination is indispensable equipment in the electrical power trans mission/distribution system, and a large amount of insulating oils that adopt guarantee the normal operation of cable termination as the insulation impregnating agent in the cable termination.At present domestic electric power development is very rapid, and a large amount of cable terminations move on transmission line of electricity, guarantees that therefore the operate as normal of cable termination just becomes very important.And insulating oil terminal inner with system's operational process in; Because there is bigger difference in the insulating material that service condition, terminal inner cooperate etc.; So the monitoring aging to the insulating oil in the at present domestic oil immersed type terminal is a crucial job; But it is very crucial how the oil sample in the cable termination to be taken a sample, and when only breaking down at the terminal in the past the oil sample of fault is done a part of testing, and the oil sample of fault tends to because the dispersiveness of failure cause causes oil sample can not reflect the real aging conditions of insulating oil; So this method provides effective guidance to the oil of getting at the scene of operation terminal insulating oil; When circuit overhauls, the insulating oil in the terminal is carried out sampling Detection, in time follow the tracks of the aging conditions of insulating oil, reach purpose terminal monitoring.This method is suitable for the oil sample sampling at the GIS terminal in the transformer station, and the oil sample at terminal sampling outside the transformer station also is suitable for the oil sample sampling of outdoor terminal.
Summary of the invention
The object of the invention is exactly the sampler that a kind of applied widely, safe, cable terminal insulation oil that accuracy is high is provided in order to overcome the defective that above-mentioned prior art exists.
The object of the invention can be realized through following technical scheme:
A kind of sampler of cable terminal insulation oil; This sampler is connected with cable termination; It is characterized in that described sampler comprises vacuum pump, first vacuum line, second vacuum line, surge flask, gets oil pipe line and insulating oil storage bottle, described vacuum pump is connected with surge flask through first vacuum line; Described surge flask is connected with the insulating oil storage bottle through second vacuum line, and described insulating oil storage bottle is connected with cable termination through getting oil pipe line.
Described surge flask upper end is provided with first rubber stopper, and described first vacuum line gets into the surge flask bottle mouth position after passing first rubber stopper, and described second vacuum line, one end gets into surge flask bottle bottom after passing first rubber stopper.
Described insulating oil storage bottle top is provided with second rubber stopper; The described second vacuum line other end gets into insulating oil storage bottle bottle mouth position after passing second rubber stopper; Described getting gets into insulating oil storage bottle bottle place, described middle part of getting oil pipe line other end insertion cable termination after oil pipe line one end passes second rubber stopper.
Compared with prior art, the present invention has the following advantages:
1, applied widely, get oil pipe line and insert from the cable termination port toward the lower end the terminal, get the length of oil pipe line according to the difference of terminal form and can adjust, guarantee to get the middle part of the inlet of oil pipe line at the terminal, being drawn oil sample to guarantee is the oil sample at middle part, terminal;
2, safe, the outlet of getting oil pipe line is passed second rubber stopper and is placed on the bottom near the insulating oil storage bottle, and second vacuum line passes rubber stopper; The mouth of pipe exposes rubber stopper and gets final product; During as the oil pumping operation, produce negative pressure in the insulating oil holding bottle, the insulating oil in the terminal is inhaled into the insulating oil holding bottle; Oil sample gets into from the bottom of bottle, prevents that oil sample directly is inhaled into vacuum line;
The part that second vacuum line inserts surge flask must be put near the surge flask bottom; First vacuum line passes rubber stopper and is connected to vacuum pump; The mouth of pipe exposes rubber stopper and gets final product, in case misoperation occurs, insulating oil can only be isolated in the surge flask; And can not be inhaled into vacuum pump, guarantee the safe in utilization of vacuum pump.
3, accuracy is high, and this is got the oily process factor that system is outside and has carried out effective isolation, guarantees that the oil sample of obtaining does not receive the interference of external factor, thereby guarantees the follow-up test result's of sample accuracy.
