Description
Technical field
This utility model relates to field transformer, is specifically related to distribution transformer security monitoring warning devices.
Background technology
Transformator (Transformer) is that the principle utilizing electromagnetic induction is to change the device of alternating voltage, main member
It is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, steady
Pressure (magnetic saturation transformator) etc.;Can be divided into by purposes: power transformer and special transformer (electric furnace change, rectification change, power frequency examination
Test transformator, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformator, instrument transformation
Device, electronic transformer, reactor, transformer etc.).Existing transformator often occurs transformator overheating conditions, transformator mistake
Heat, the most then affect service life (if transformator service life at normal working temperature 90 DEG C is 20 years;If temperature rises to 105
DEG C, then the life-span is 7 years;Temperature is raised to 120 DEG C, and the life-span is only 2 years), heavy then oil jetting combustion or blast occur.Cause transformator mistake
The reason of heat has: loose contact, contact resistance is big;Long-term serious running overload, makes coil heating;Overtension, iron loss increases
Greatly (when voltage increases 10%, iron loss will increase by 30%~50%);Ambient temperature is too high, improper ventilation;Transformator is the most frequent
The situation of load short circuits occurs, and load is short-circuited, and transformator bears huge short circuit current, if protection system down or whole
Definite value adjusts excessive, it is possible to burn transformator.Short-circuit protection is installed, and the selection of melt must meet the requirements, and works as change
During depressor internal short-circuit, high-pressure side should be able to fuse rapidly, respectively draws loop when transformator and is short-circuited or low-pressure side during heavy overload
Can be blown.
Patent No. CN103427488A discloses a kind of box type transformer monitoring system, and it includes casing, is arranged on case
Internal transformator and monitoring system, described monitoring system include low-pressure side voltage collection circuit, high side voltage Acquisition Circuit,
Microprocessor module, communication module, temperature collect module, humidity collection module, drive circuit, multiple it is uniformly arranged on described case
Exhaust fan on body sidewall and host computer, described microprocessor module can by the step down side information of voltage collected,
In high side voltage information, casing, temperature information and casing humidity information carry out uploading and are easy to regulation and control, simultaneously can be according to adopting
Collect to temperature information and humidity information judge whether to open described exhaust fan;The security incident of transformator can not be entered by this system
Row alarm, it is impossible to automatically process accident.
