Utility model content
The technical problems to be solved in the utility model is: for the deficiencies in the prior art, provide a kind of structure simple, easy to use, both conveniently carried out analyzing detect, cost of labor when again reducing detection, the transformer oil standard oil sample hold-up tank that can also ensure standard oil sample stability, improve accuracy in detection.
The utility model solves the technical scheme that its technical matters adopts:
A kind of transformer oil standard oil sample hold-up tank, comprise support, above support, fuel tank is set, fuel tank top sets out gas port and vacuum orifice, and tank bottoms arranges heating arrangement and oil-in, and fuel tank internal is provided with dilation device, fuel tank side sets out hydraulic fluid port and oil level indicator, tank bottoms arranges the first oil-out, and the first oil-out connects the entrance of ebullator by pipeline, and circulation delivery side of pump connects the first oil-in being arranged on fuel tank side by circulation line.
Preferably, described dilation device top is connected by ring flange with top of oil-tank.Dilation device is air bag, and when using hold-up tank, air bag becomes cylindric, and match with the structure of fuel tank internal cylindrical shape, air bag top has one for passing in and out the perforate of gas, and this perforate is corresponding with the gas outlet of top of oil-tank.
Preferably, described heating arrangement is heating plate.
Preferably, gas outlet is arranged on the centre position of top of oil-tank, and vacuum orifice is arranged on top of oil-tank side, makes hold-up tank compact appearance, attractive in appearance.
Preferably, set temperature sensor on the connecting tube of circulation delivery side of pump and the first oil-in.Can the temperature of Real-Time Monitoring standard oil sample, prevent the stability affecting standard oil sample too high or too low for temperature.
Preferably, oil-out and oil level indicator are arranged on the homonymy of fuel tank.Make hold-up tank compact appearance, attractive in appearance.
Described transformer oil standard oil sample hold-up tank can the height of adjusting pole as required, fuel tank is fixed on support, by arranging heating arrangement at tank bottoms, the standard oil sample in fuel tank is heated, be heated evenly to make the standard oil sample in fuel tank, between tank bottoms first oil-out and side first oil-in of fuel tank side surface upper part, ebullator is set, oil is constantly circulated, make standard oil sample thermally equivalent, ensure the stability of standard oil sample, structure is simple, easy to use.Dilation device adopts air bag, in use, air between air bag and inner wall of oil tank is vacuumized, now air bag can be close to oil reservoir surface and inner wall of oil tank, effectively air is separated with standard oil sample, ensure that the purity of standard oil sample, the standard oil sample avoided in fuel tank is subject to pollution to a certain extent, affects the accuracy that post analysis detects.When adding standard oil sample, cylindric air bag just raises along with the rising of oil level, and the gas in air bag can be discharged from gas outlet.
The beneficial effect that the utility model has is:
Tank body directly can be transported near transformer and be proofreaded transformer on-line chromatograph analyser by standard oil sample by transformer oil standard oil sample hold-up tank described in the utility model, and the utility model be normal pressure and with heating and circulation, can the true running status of analogue transformer really, ensure that transformer runs the accuracy detected, reduce the workload of staff, under the state of uninterrupted transformer work, accurately can detect analysis to it.The utility model, in order to the accuracy of the stability and testing result that ensure standard oil sample, increases heating arrangement at tank bottoms, makes the temperature that the standard oil sample in fuel tank keeps certain, good stability, and structure is simple, easy to use.
