Description

A kind of transformer detecting system

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, Including transformer unit, the transformer unit is connected with current transformer and voltage transformer, the current transformer and electricity Pressure transformer is connected to filter circuit, and the filter circuit is connected to A/D change-over circuits, and the A/D change-over circuits are connected to micro- Processor, the microprocessor are connected with wireless communication module, storage 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.

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is theory diagram of the present utility model.

Embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to The scope of the utility model protection.

Embodiment：

As shown in figure 1, a kind of transformer detecting system, including transformer unit, the transformer unit are connected with electric current Transformer and voltage transformer, the current transformer and voltage transformer are connected to filter circuit, the filter circuit connection To A/D change-over circuits, the A/D change-over circuits are connected to microprocessor, and the microprocessor is connected with wireless communication module, storage Storing module, locating module, alarm modules and temperature sensor.

Preferably, the locating module is d GPS locating module.

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 Modification is replaced, and the essence of appropriate technical solution is departed from the spirit and model of various embodiments of the utility model technical scheme Enclose.
