Abstract
The utility model provides an accurate sampling device of insulating oil of transformer, is including sample three -way valve (2), sampling bottle (3) and ONLINE CHROMATOGRAM appearance (4). The input port of sample three -way valve connects transformer (1) oil tank, the output port's of sample three -way valve a termination ONLINE CHROMATOGRAM appearance, oil appearance re -entering after the analysis of ONLINE CHROMATOGRAM appearance returns the transformer, the output port's of sample three -way valve an other termination sampling bottle, the oil appearance of taking out send the laboratory to carry out assay. The utility model discloses accurate sampling device of insulating oil of transformer not only can be through the insulate rapid sampling of oil of three -way valve, has practiced thrift and has arranged time of remaining insulating oil in the space -variant depressor body sampling probe, the device carries out the accuracy sample under can also the condition of ONLINE CHROMATOGRAM appearance work, and the oil appearance of avoiding getting makes oil appearance representative for stagnant oil in the transformer, has guaranteed accuracy, the reliability of insulating oily chromatography data from the source.
Description
Technical field
This utility model is related to a kind of accurate sampler of transformer insulation oil, belongs to transformer insulation oil Site Detection skill
Art field.
Background technology
By being sampled to the insulating oil of transformer body, and gas chromatographic analysiss are carried out to the dissolved gas in oil,
Monitoring transformer station high-voltage side bus situation has been the effective means that a kind of generally acknowledged guarantee transformer safety is run.At present, power industry will
330kV and above transformator is asked to take within 3 months a sample, 220kV transformator takes a sample, 110kV and following transformator 12 for 6 months
Take within individual month a sample.At home, transformer insulation oil sampler is typically all arranged on middle part on transformer body, bottom,
The insulating oil of residual in sampling head to be emptied before every sub-sampling, this is accomplished by taking some time, if not sampling head
Interior immobilising oil can be very big on testing result impact, or even misleading produces operation maintenance personnel, leads to operating transformer to have an accident,
Impact power grid security.
In recent years, transformator chromatogram monitoring technology detects as lab analysis supplement and development, because it has
Analytical cycle is short, the advantage of continuous on-line monitoring, it is possible to achieve the on-line monitoring to transformer fault, to the generation avoiding accident
Play an important role.Online gc is used for automatic data collection, separation, detection characteristic gas constituent content, the oil sample of this device
Harvester all can be sampled once daily, and the oil sample in pipeline can flow, and then return oil sample in transformator, protect
Demonstrate,proved in sampling pipe is to flow through, from transformer body, the abundant circulation oil sample coming.Above-mentioned sampling for online gc is special
Levy, a three-way valve can be installed on its sampling conduit and sampled, the oil sample so allowing for gathering is representative,
It is the fresh oil sample of flowing.
Content of the invention
The purpose of this utility model is that there is inaccurate problem according to the sampling of existing transformer insulation oil, open a kind of
The accurate sampler of transformer insulation oil.
This utility model be employed technical scheme comprise that：A kind of accurate sampler of transformer insulation oil includes sampling three
Port valve, sampling bottle and online gc.The input port of sampling T-way valve connects oil tank of transformer, the output port of sampling T-way valve
Wherein one end be connected on line chromatograph, oil sample through online gc analysis after return again to transformator；The outfan of sampling T-way valve
The other end of mouth connects sampling bottle, and the oil sample of taking-up is brought back laboratory and is analyzed.
Operation principle of the present utility model is that, during the accurate sampler work of transformer insulation oil, online gc will
Insulating oil on closed circuit in transformator is gathered once a day by sample lines, then the oil after analysis is back to transformation
Device fuel tank, it is up-to-date for this assures the oil sample in sampling line, is consistent with transformer body oil.When need gather
Transformer insulated oil sample to laboratory be analyzed when it is possible to directly open install online gc sampling line on threeway
Valve is sampled it is ensured that sampling the quick, accurate of link.
The beneficial effects of the utility model are that the accurate sampler of this utility model transformer insulation oil not only can lead to
Cross the fast sampling that three-way valve carries out insulating oil, save the time of residual insulating oil in emptying transformer body sampling head；Should
Device accurately can be sampled with the case of online gc work, it is to avoid the oil sample got is immobilising in transformator
Oil, makes oil sample representative, ensure that accuracy, the reliability of dielectric oil chromatographic analysis data from source.
This utility model is applied to the oil-filled transformer being mounted with online gc.
Brief description
Fig. 1 is the structural representation of this utility model device；
In figure figure number：1 is oil-filled transformer；2 is sampling T-way valve；3 is sampling bottle；4 is online gc.
Specific embodiment
With reference to embodiments and compare accompanying drawing this utility model is described in detail.
As shown in figure 1, the accurate sampler of the present embodiment transformer insulation oil by sampling T-way valve 2, sampling bottle 3 and
Line chromatograph 4 forms.
At close oil-filled transformer 1 on the sampling pipe of online gc 4, insulating oil sampling T-way valve 2 is installed, takes
The input port of sample three-way valve 2 connects oil-filled transformer 1, and one of output port of sampling T-way valve 2 connects online gc
4, oil sample returns again to oil-filled transformer 1 after online gc 4 analysis；The another one output port of sampling T-way valve 2 connects
Sampling bottle 3, the oil sample of taking-up is brought back laboratory and is analyzed.
Claims (1)
1. a kind of accurate sampler of transformer insulation oil is it is characterised in that described device includes sampling T-way valve, sampling bottle
And online gc；The input port of described sampling T-way valve connects oil tank of transformer, one end of the output port of sampling T-way valve
Connect online gc；Oil sample returns again to transformator after online gc analysis；Other the one of the output port of sampling T-way valve
