Abstract
The invention discloses an oil sampling tool for a main transformer. The oil sampling tool comprises a sampling bottle (1), a waste oil bottle (2) and vacuumizing sampling equipment (3). One end of a main transformer oil pipe (4) is extended into the sampling bottle (1). An oil drain valve (5) is arranged on the main transformer oil pipe (4). The end, extended into the sampling bottle (1), of the main transformer oil pipe (4) is provided with a sampling valve (6) which is positioned in the sampling bottle (1). The bottom of the sampling bottle (1) is provided with an oil leakage port I (7) and an oil leakage port II (8). The oil leakage port I (7) is communicated with the waste oil bottle (2) by a pipeline I (9). The oil leakage port II (8) is communicated with an inlet of the vacuumizing sampling equipment (3) by a pipeline II (10). The oil sampling tool not only can effectively protect an environment, but also can achieve good sampling effects and ensure high measurement accuracy.
Description
Technical field
The present invention relates to a kind of oil sampling tool for main-transformer.
Background technology
At present because the carrying out of repair based on condition of component, equipment power failure cycle stretch-out, and oiling the non-power failure pilot project cycle such as is tested and is shortened.220kV and above main-transformer oil chromatography cycle are 3 months, and 110kV and following chromatogram cycle are 6 months, and the frequency that main transformer draws oil sample improves greatly.Usually having between the sample valve of carrying and the main-transformer body of main-transformer is communicated with by very long one section oil pipe, but the damage ratio that the oil sample of this section oil pipe often is subject to is more serious, the oil sample that can not truly reflect the main-transformer body, usually need to bleed off the oil sample that just can get oily body to the oil of oil-piping the inside when therefore we draw oil sample, although and the sample valve of main-transformer from the main-transformer body close to, but valve port is larger, diameter greater than the sampling bottleneck, transformer oil easily is dropped in around the sample valve during so that draw oil sample, contaminated environment affects the clean condition of transformer station.The existing defective that draws oil sample: it all is directly to bleed off with the oil that has been subjected to pollute of Plastic Drum this section oil-piping that present oiling class draws oil sample usually, the on-the-spot easily a lot of transformer oil of water clock, environment easily destorys the scene, and because oil-piping is long and the valve port of draining the oil is larger, even put a lot of oil still the old oil that much has been subjected to pollute remain in the fuel outlet place so that the oil sample that takes out can not truly not reflect the quality of transformer oil product.
Summary of the invention
The invention provides a kind of oil sampling tool for main-transformer, it not only can effectively protect environment, and the effect of sampling, measures accurately.
The present invention has adopted following technical scheme: a kind of oil sampling tool for main-transformer, it is characterized in that described sampling jar, waste oil bottle and vacuumize sampling equipment, one end of main-transformer oil pipe extend in the sampling jar, be provided with fuel outlet valve at the main-transformer oil pipe, an end that stretches into sampling jar at the main-transformer oil pipe is provided with sample valve, sample valve is positioned at sampling jar, be respectively equipped with oil leakaging port I and oil leakaging port II at the end of sampling jar, be communicated with the waste oil bottle by pipeline I at oil leakaging port I, on oil leakaging port II, be communicated with the import that vacuumizes sampling equipment by pipeline II.
The described sampling equipment that vacuumizes is set to vacuum syringe.Described oil leakaging port I and oil leakaging port II place are provided with respectively valve I and valve II.
The present invention has following beneficial effect: sample valve of the present invention is arranged in sampling jar, so just the sampling valve port can be encased fully, then go waste oil to become reconciled oily passage separately, avoid oil sample to pollute, waste oil can access good collection and treatment simultaneously, and it is applicable to different transformers like this, can better collect waste oil, and waste oil and cleansing oil are well separated, so that the better data of embodiment device body of test figure.Use simultaneously this instrument can keep the work on the spot environment clean and tidy, shorten working hours, be conducive to carrying out of work, the precision of measuring in addition is high.
Description of drawings
Fig. 1 is structural representation of the present invention
Embodiment
In Fig. 1, the present invention is a kind of oil sampling tool for main-transformer, sampling jar 1, waste oil bottle 2 and vacuumize sampling equipment 3, vacuumize sampling equipment 3 and be set to vacuum syringe, one end of main-transformer oil pipe 4 extend in the sampling jar 1, be provided with fuel outlet valve 5 at main-transformer oil pipe 4, an end that stretches into sampling jar 1 at main-transformer oil pipe 4 is provided with sample valve 6, sample valve 6 is positioned at sampling jar 1, be respectively equipped with oil leakaging port I 7 and oil leakaging port II 8 at the end of sampling jar 1, oil leakaging port I 7 and oil leakaging port II 8 places are provided with respectively valve I 11 and valve II 12, be communicated with waste oil bottle 2 by pipeline I 9 at oil leakaging port I 7, on oil leakaging port II 8, be communicated with the import that vacuumizes sampling equipment 3 by pipeline II 10.When main fransformer oil begins to draw oil sample, open first the valve I 11 of the oil leakaging port I 7 that connects waste oil bottle 2, close the valve II 12 of the oil leakaging port II 8 that vacuumizes sampling equipment 3, this time, waste oil will flow to 2 li in waste oil bottle, when by observe waste oil in the sampling jar 1 put clean after, close the valve I 11 that connects waste oil bottle 2, open the mouth of valve II 12, take out behind enough oil samples again valve-off II 12.Then take off sampler.The work of drawing oil sample has just been finished.
