Abstract
The present invention relates to the transformer alarm systems in transformer alarm field, metal pedestal including being used to be attached to transformer surface, cylinder body is connected in metal pedestal, the cylinder body includes liquid storage cylinder and battery cavities successively, mercury is filled in liquid storage cylinder, interval is combined with dry cell in battery cavities, and dry cell offsets with mercury；Alarm is installed, alarm is equipped with the contact chip being connected with dry cell on the cylinder body.In use, being attached to the metal pedestal on transformer surface, by the heat transfer on transformer surface to the mercury in liquid storage cylinder, volume expands after mercury is heated, and then promotes and moved with the dry cell that it offsets towards alarm；When under the heat that mercury is distributed in transformer, volume expansion is to after certain so that dry cell is in contact with contact chip, and then triggers alarm, the monitoring of completion transformer surface temperature.
Description
Technical field
The present invention relates to transformer alarm fields, and in particular to transformer alarm 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 convert, isolate, is steady
It presses (magnetic saturation transformer) etc..
But transformer is in use, can generate substantial amounts of heat so that the surface temperature of transformer drastically raises,
After more than the safe temperature of transformer, spontaneous combustion easily occurs for transformer, causes transformer damage；But do not have also on the market at present
There is the detection raised device of transformer surface temperature.
The content of the invention
The invention is intended to provide transformer alarm system, to solve that the device of transformer surface temperature can not be monitored.
Transformer alarm system in this programme, the metal pedestal including being used to be attached to transformer surface, in metal pedestal
Cylinder body is connected with, the cylinder body includes liquid storage cylinder and battery cavities, coordinates in liquid storage cylinder filled with mercury, the interior interval of battery cavities successively
There is dry cell, dry cell offsets with mercury；Alarm is installed, alarm connects equipped with what is be connected with dry cell on the cylinder body
Contact.
The operation principle and its advantage of this programme：In use, the metal pedestal on transformer surface is attached to, by transformer
The heat transfer on surface is to the mercury in liquid storage cylinder, and volume expands after mercury is heated, and then promotes the dry electricity to offset with it
It is moved towards alarm in pond；When under the heat that mercury is distributed in transformer, volume expansion is to after certain so that dry cell is with contacting
Piece is in contact, and then triggers alarm, completes the monitoring of transformer surface temperature.
Further, sealing ring is equipped between the battery cavities and dry cell.Increase battery cavities seem leakproofness with dry cell, keep away
Exempt from heat to scatter and disappear.
Further, the alarm is to be detachably connected with cylinder body.It is convenient for changing the alarm of damage.
Further, the metal pedestal is filled with heat conductive silica gel with transformer bay.The heat distributed convenient for transformer is rapid
It is transferred in metal pedestal.
Description of the drawings
Fig. 1 is the structure diagram of transformer alarm system of the present invention.
Specific embodiment
Below by the further details of explanation of specific embodiment：

Eight air inlets are offered on wind face side by side, eight air outlets are offered side by side on leeward, which is right against coolant jacket,
2 times of 2~3 times of a diameter of air outlet diameter of air inlet, the in the present embodiment a diameter of air outlet diameter of air inlet.
Conical metal pipe is connected between air inlet and air outlet, while covered with one layer of filter screen, mistake on air inlet
Strainer is to be detachably connected with air inlet；Water feeding tank is communicated with a pair of of circulating water pipe with cooling inner room, is equipped on circulating water pipe
One suction pump, suction pump, rotating plate and forms closed circuit by movable plate.
In use, the metal pedestal on transformer surface is attached to, by the heat transfer on transformer surface to the water in liquid storage cylinder
Silver, volume expands after mercury is heated, and then the dry cell 3 to offset with it is promoted to be moved towards alarm 4；When mercury is in transformation
Under the heat that device distributes, volume expansion is to after certain so that and dry cell 3 is in contact with contact chip, and then triggering alarm 4,
Complete the monitoring of transformer surface temperature.
Above-described is only the embodiment of the present invention, and the common sense such as well known concrete structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
