Description
Technical field
The utility model is related to a kind of portable converter power transformer gas collectors.
Background technology
Inside transformer may have a failure of two kinds of forms of hot-spot shelf depreciation in operation, when failure around fault point
Transformer oil and solid insulating material gas is generated because of fever, wherein most gas constantly dissolves in oil, but works as failure
Development is very fast, and the gas of generation is more to be had little time to dissolve or be saturated and run toward conservator direction, when running to gas, due to gas top
Portion protrudes, and is higher than the connecting pipe of conservator and ontology, at gas is integrated at the top of gas, under conservator oil pressure gas toward gas after
Electric appliance takes gas box direction to run.
Buchholz relay is a kind of common important protective device of oil-immersed transformer.It is mounted on transformer and conservator
Between connecting line in.When inside transformer breaks down, the gas of generation or caused by oil flow surge, relay can be made
Contact action, specified control loop is connected, and send out signal in time or cut off transformer automatically, to prevent fault coverage
Further expand.When transformer works normally, insulating oil is filled with inside Buchholz relay.Inner air should be arranged by maintenance
It removes, when transformer breaks down in operation, the transformer oil of fault point is decomposed, and the gas generated is in gas relay
Assemble and Buchholz relay is made to act in inside.In order to judge what the residual air not drained when maintenance or internal fault generated
Gas should take gas to carry out chromatography when there is the action of main transformer body gas.The component and content of these gases are to judge
Equipment is with the presence or absence of failure and one of the important evidence of nature of trouble.There is the influence of different back dissolving rates to reduce different component, it must
Gas sample must be taken out in the shortest possible time, and analyze as early as possible, to judge the property and failure of power transformer interior fault
Severity, development speed and trend.The clear gas relay in the operating provisions in relation to gas relay in relevant regulations
Answer periodic check.When gas relay is when sending out light gas actuating signal, gas relay should be checked immediately, takes gas in time
Sample, to distinguish gas componant.
When transformer works normally, insulating oil is filled with inside Buchholz relay.Inner air should by reparing,
When transformer breaks down in operation, the transformer oil of fault point is decomposed, and the gas generated is in gas relay
Assemble and Buchholz relay is made to act in portion.In order to judge the gas of the residual air not drained when maintenance or internal fault generation
Body should take gas to carry out chromatography when there is the action of main transformer body gas.The component and content of these gases are to judge to set
Standby one of the important evidence that whether there is failure and nature of trouble.There is the influence of different back dissolving rates to reduce different component, it is necessary to
Take out gas sample in the shortest possible time, and analyze as early as possible, to judge power transformer interior fault property and failure it is tight
Weight degree, development speed and trend.《18, state's net is counter to arrange》Clear gas relay in operating provisions in relation to gas relay
Device answers periodic check.When gas relay is when sending out light gas actuating signal, gas relay should be checked immediately, takes gas in time
Sample, to distinguish gas componant.
Utility model content
The purpose of this utility model is to provide a kind of portable change of current transformation easy to use, simple in structure, safe and reliable
Device gas collector.
A kind of portable converter power transformer gas collector, is particular in that：Including medical three-way valve, this is medical
The air inlet of triple valve is connect with one end of the first hose, and a gas outlet of the medical three-way valve passes through the second hose and transformation
The gas vent of the gs-oil separator inlet communication of device oil, the gs-oil separator takes gas test tube by connecting tube with plug
Connection, further includes syringe, the syringe needle of the syringe is stretched by plug to be taken in gas test tube.
Wherein syringe uses the glass syringe of 100ml.
Wherein the first hose and the second hose are all made of medical latex tube.
Valve wherein is installed on the second hose.
Test proves that after using utility model device, can be gathered inside gas relay with accurate judgement gas
Collection is the residual air not drained when maintenance or the gas that internal fault generates, to judge the property of power transformer interior fault
And severity, development speed and the trend of failure.It has many advantages, such as easy to use, simple in structure, safe and reliable, contributes to
Potential problems existing for timely discovering device.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, the utility model provides a kind of portable converter power transformer gas collector, including medical three
Port valve 1, the air inlet of the medical three-way valve 1 are connect with one end of the first hose, and a gas outlet of the medical three-way valve 1 passes through
6 inlet communication of gs-oil separator of second hose 3 and transformer oil, the gas vent of the gs-oil separator 6 by connecting tube with
It takes gas test tube 5 to be connected to plug, further includes syringe 4, the syringe needle of the syringe 4 is stretched by plug to be taken in gas test tube 5.
Wherein for syringe 4 using the glass syringe 4 of 100ml, the first hose and the second hose 3 are all made of medical latex
Pipe, is in addition equipped with valve 2 on the second hose 3.
The application method and operation principle of the utility model be：
First by one headgear of the first hose on the deflating valve of the collector box of gas relay, connection should be secured, by this
The other end of one hose is connected to 1 air inlet of medical three-way valve, and a gas outlet of medical three-way valve 1 is connect with gs-oil separator 6,
Medical three-way valve 1 and valve 2 are opened, after realizing Oil-gas Separation in gs-oil separator 6, gas, which enters, takes gas test tube 5, passes through note
Emitter 4 takes gas, gas content to take to 80mL, closes medical three-way valve 1, removes and uses small Capsule instead immediately after syringe 4 and seal
Syringe 4.Then taking gas test tube 5, gs-oil separator 6 and second hose 3 etc. to take off together, the collection of gas relay is closed
The air relief cock of gas box finally removes medical three-way valve 1.
