A temperature measurement element is arranged on a surface of the winding of the low tension winding, and one end of the temperature measurement element is connected with an outgoing line. The utility model realizes to real-timely reflect actual temperature of the three-phase winding of the transformer and generate over-temperature alarm signals, meanwhile realizes remote transmission of the temperature and the alarm signals.
Description
Technical field
The utility model relates to oil immersion-type distribution transformer, relates in particular to a kind of oil immersion-type distribution transformer with winding temperature measurement function.
Background technology
Existing transformer winding and iron core in running can distribute a large amount of heats, these heats directly have influence on the stability and the useful life of transformer, in order to make transformer stable operation, usually need the Transformer Winding temperature is calculated, the heating of transformer mainly is that the electric current by winding causes, high and low pressure heating in winding amount is suitable, general temperature rise is also approaching, and radiating condition was poor in the middle of the low pressure winding was wrapped in by the high pressure winding, mainly was to measure the low pressure winding temperature so measure the temperature of winding.
The solution one that exists is to calculate the temperature of winding by surveying temperature of oil in transformer at present.Solution two is the transformer that has a power failure to be calculated the temperature of winding by the D.C. resistance of surveying winding.But solution one can not be correct the true temperature of reflection winding, solution two can not reflect the true temperature of winding in real time, and complicated operation.Simultaneously, scheme one, two all can not provide real-time overtemperature alarm signal.
The utility model content
In order to overcome the deficiency that prior art exists, the utility model aims to provide a kind of oil immersion-type distribution transformer with winding temperature measurement function, to be implemented in real-time reflection transformer three phase winding actual temperatures in service and to send real-time overtemperature alarm signal, realize the purpose of the remote transmission of temperature and alarm signal simultaneously.
A kind of oil immersion-type distribution transformer described in the utility model with winding temperature measurement function, comprise the fuel tank that is filled with transformer oil, be immersed in described transformer by in the device body, wherein, the device body comprises unshakable in one's determination and is installed in the interior winding of described window unshakable in one's determination, and this winding is made up of the low pressure winding high pressure winding outer with being arranged on this low pressure winding, it is characterized in that: the winding surface at described low pressure winding oil duct is provided with a temperature element, and an end of this temperature element is connected with a lead-out wire.
In above-mentioned oil immersion-type distribution transformer, also comprise a control instrument that is arranged on the terminal box on the described fuel tank and is connected with described terminal box, and the terminal of described terminal box is connected with described lead-out wire by the connection lead with winding temperature measurement function.
In the above-mentioned oil immersion-type distribution transformer with winding temperature measurement function, described control instrument has a PORT COM.
Owing to adopted above-mentioned technical solution, the utility model passes through pre-buried temperature element in the low pressure winding of transformer body, thereby in the transformer true temperature that can reflect winding correctly, in real time in service; The control instrument that is connected with temperature element possesses real-time demonstration, overload alarm and communication function in addition, and real-time overtemperature alarm signal can be provided again, makes transformer can realize the remote transmission function of winding temperature demonstration in real time, overload alarm and signal.
