The vacuum oil filtering and nitrogen charging device has the advantages of being compact in structure, small in size, low in weight, convenient to use and maintain, capable of achieving the nitrogen injecting function and protecting the device form being polluted by the air due to the fact that nitrogen is injected during oil processing of the transformer and the like.
Description
Technical field
The utility model relates to vacuum oil filtering technology, especially a kind of transformer vacuum oil strain nitrogen charging device.
Background technology
Transformer, in long-term operation, makes transformer oil contain moisture content, and air and impurity cause transformer oil dielectric strength to reduce, and radiating effect is poor, and to transformer, operation is made troubles, therefore need be to transformer oil purified treatment.Traditional transformer has two oilholes, a fuel feed hole, and another is oil outlet.By the pump being equipped with in vacuum oil filtering cleaning equipment, transformer oil is extracted out and entered vacuum oil filtering cleaning equipment by oil outlet, after purified treatment, pump into again transformer, because the conservator of transformer has a structure of breathing hole, air intake, make purified treatment, the continuous purified treatment that circulates, exists time-consuming weak point.
For electric locomotive, be equipped with transformer, owing to limited by operational environment, the one, volume of transformer is little, the 2nd, transformer change loose device and conservator is integrated, and design in the above, different with general transformer device structure, because structure is special, can not adopt the circularly purifying processing mode of traditional transformer oil.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model provides, and adopts the nitrogen technology of filling, the transformer oil dehydration to locomotive transformer, the degassed purified treatment nitrogen charging device with removing grain husk grain pollutant.
The purpose of this utility model adopts technical scheme, comprise nitrogen cylinder, external fuel tank, transformer, vacuum oil-filter, the efferent duct of its nitrogen cylinder connects the input of nitrogen valve, the input of the output termination permeation valve of nitrogen valve and the input that rushes nitrogen valve, rush the nitrogen inlet hole of the output termination transformer of nitrogen valve, the oilhole of transformer connects the input of fuel feeding valve, the fuel feed hole of output termination vacuum oil-filter of fuel feeding valve and the input of fuel tank inlet valve, the output termination external fuel tank fuel feed hole of fuel tank inlet valve, the input of external fuel tank oil outlet connected tank delivery valve, fuel tank goes out the fuel feed hole of the output termination vacuum oil-filter of fuel tank.
Also have, the pipeline at output of nitrogen valve is connected to gas gauge.
The course of work of the present utility model, nitrogen flows into from breakdown nitrogen valve the permeation valve opening and closing and rushes nitrogen valve to unlatching, enters in transformer, and nitrogen pressure makes the transformer oil of transformer flow out to external fuel tank from fuel feeding valve.Close transformer pouring fuel tap, open external fuel tank delivery valve and external fuel tank inlet valve, start vacuum oil-filter the fluid of external fuel tank is carried out to circulating vacuum oil strain purified treatment.When the oil liquid vacuum purification of external fuel tank process qualified after, close the inlet valve of external fuel tank, fuel feeding valve and nitrogen permeation valve, the vacuum oil-filter of opening transformer inject the qualified fluid of external fuel tank in transformation.The fluid that nitrogen in transformer is injected into is replaced gradually from nitrogen permeation valve and is overflowed.Fluid is closed the fuel feeding valve of transformer and rushes nitrogen valve after filling with transformer.Thereby complete the oil processing process of this transformer.
The utility model, compact conformation, volume are little, lightweight, operation and maintenance convenient, there is note nitrogen function, when transformer insulation oil is processed, in the process being drawn out of at insulating oil, nitrogen charging device is progressively replaced the insulating oil in transformer cavity with nitrogen, avoid the pollution of external humidification air, guaranteed the dry of transformer inside, for the insulating oil of handling well, to note back transformer ready, avoids secondary pollution.
