Description
Technical field
The utility model is related to transformer technology field, more particularly to a kind of transformer seal test device.
Background technology
It is well known that voltage transformer (Potential transformer abbreviations PT, Voltage transformer
Abbreviation VT) and transformer it is very alike, be all the voltage on conversion line.But the purpose of transformer voltage of transformation be in order to
Conveying electric energy, therefore capacity is very big, typically all with kilovolt-ampere or megavolt-ampere be unit of account；And voltage transformer voltage of transformation
Purpose, be primarily used to be powered to measuring instrumentss and protective relaying device, for the voltage of measurement circuitry, power and electric energy,
Or for the expensive equipment in the protection circuit in line failure, motor and transformer, therefore voltage transformer appearance
Amount very little, typically all only several volt-amperes, tens volt-amperes, hundreds of volt-amperes.But in some Code in Hazardous Special Locations, then need kilovolt-ampere
Voltage transformer；In this kind of large-scale voltage transformer, it is the voltage transformer with fuse to have some；
Voltage transformer is one with transformer unshakable in one's determination.It is mainly made up of first and second coil, unshakable in one's determination and insulation.When
When applying a voltage U1 in first winding, a magnetic flux φ is just produced in iron core, according to the law of electromagnetic induction, then two
A secondary voltage U2 is just produced in secondary winding.Change once or Secondary Winding the number of turn, different primary voltages can be produced
With secondary voltage ratio, this can constitute voltage transformer not on year-on-year basis.High voltage is converted into voltage transformer low electricity in proportion
Pressure, i.e. 100V, voltage transformer primary side is connected on primary system, secondary side joint measuring instrumentss, relay protection etc.；Mainly electromagnetism
(capacitance type potential transformer is widely used) of formula, separately there is non electromagnetic, such as electronic type, photo-electric.
Full-enclosed oil-immersed transformer is made up of the part such as casing, insulator, oil level indicator, shunting switch, and each several part is to pass through
Welding, sealed using cushion rubber or glue bead, because of raw material deficiency in itself, along with the careless omission of operative, accidental meeting
The situation for having casing or sealing position leakage of oil occurs.Needs carry out leak check to the transformer after the completion of assembling.Cause
This, designs and develops a kind of transformer seal test device seems it is particularly important.
