Description
Technical field
It the utility model is related to field transformer, and in particular to a kind of transformer detecting system.
Background technology
Transformer (Transformer) is the device for changing alternating voltage using the principle of electromagnetic induction, main member
It is primary coil, secondary coil and iron core (magnetic core).Major function has:Voltage transformation, current transformation, impedance are converted, isolated, be steady
Press (magnetic saturation transformer) etc.;It can be divided into, according to use,:Power transformer and special transformer (electric furnace change, rectification change, power frequency examination
Test transformer, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformation
Device, electronic transformer, reactor, transformer etc.).Transformer overheating conditions, transformer mistake often occur in existing transformer
Heat, gently then influenceing service life, (such as transformer service life at 90 DEG C of normal working temperature 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 generation oil jetting combustion or blast.Cause transformer mistake
The reason for hot, has:Loose contact, contact resistance are big;Long-term serious running overload, makes coil heating;Overtension, iron loss increase
(when voltage increases 10%, iron loss will increase by 30%~50%) greatly;Environment temperature is too high, improper ventilation;Transformer is also frequent
The situation of load short circuits occurs, short circuit occurs for load, and transformer bears huge short circuit current, if protection system down or whole
Definite value adjustment is excessive, it is possible to burns transformer.Short-circuit protection is installed, and the selection of melt must meet the requirements, and work as change
High-pressure side should be able to fuse rapidly during depressor internal short-circuit, when transformer respectively draws low-pressure side when short circuit or heavy overload occur for loop
It can be blown.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of transformer detecting system so that can be effective
Transformer is monitored.
To realize object above, the utility model is achieved by the following technical programs:A kind of transformer detecting system,

Storing module, locating module, alarm modules and temperature sensor.
Preferably, the temperature sensor is placed on inside transformer unit, for detecting transformer operating temperature.
Preferably, the alarm module includes light alarm module and sound alarm module.
Preferably, the locating module is d GPS locating module.
Preferably, the wireless communication module is ZigBee communication module or gsm communication module one kind therein.
The utility model provides a kind of transformer detecting system, effectively transformer can be monitored, work as transformation
When device occurs abnormal, transformer information can be sent to by monitor terminal by wireless communication module, monitor terminal passes through positioning
Module is positioned to transformer and excludes maintenance personal to repair, and can avoid transformer damage and nobody learns.
Temperature sensor is placed on inside transformer unit, for detecting transformer operating temperature, current transformer and electricity
Pressure transformer can detect running state of transformer, and locating module is used to position transformer current location, can also risen
To antitheft effect;Alarm modules can remind surrounding population transformer to damage.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations;Although with reference to foregoing reality
Example is applied the utility model is described in detail, it will be understood by those within the art that:It still can be to preceding
State the technical scheme described in each embodiment to modify, or equivalent substitution is carried out to which part technical characteristic;And these
