Description
Technical field
The utility model relates to the winding temperature detection technique fields of power transformer, and in particular to one kind has transformer
The power transformer of winding temperature display function.
Background technique
Power transformer is most important in power grid and most expensive one of equipment, its safe and reliable direct relation is defeated
Power transformation power grid whether stable operation.The life termination of power transformer is because it loses due insulating capacity, and influences
The temperature of winding, i.e. hot spot temperature of winding when the principal element of insulating capacity is transformer station high-voltage side bus.
Transformer high-voltage bushing is the insulating sleeve guided to high and low pressure lead inside power transformer outside fuel tank, no
But as lead insulation against ground, and it being responsible for the effect of anchor leg, bushing shell for transformer is one of transformer current carrying element,
Transformer passes through short circuit current when transformer short-circuited outside for a long time by load current.
Since transformer winding temperature influences the service life of power transformer, accordingly, it is desirable to provide a kind of mode can
The temperature of real-time monitoring transformer winding.
Utility model content
The purpose of the utility model is to provide a kind of power transformer with transformer winding temperature display function, energy
The temperature of enough real-time display transformer windings, and then improve the service life of power transformer.
To achieve the goals above, technical solution adopted in the utility model is as follows:
A kind of power transformer with transformer winding temperature display function, including transformer high-voltage bushing, transformer
Winding and transformer case, transformer high-voltage bushing include conducting rod, insulating layer and insulating coating, conducting rod and transformer winding
Connection；It is characterized by: the power transformer further includes temperature sensor and temperature display meter, transformer case is equipped with and is used for
The mounting hole of temperature display meter is installed, insulating layer is equipped with groove in the position close to conducting rod, and temperature sensor is placed on recessed
In slot, temperature sensor is connect by electric wire with temperature display meter, the temperature of temperature sensor real-time detection conducting rod, and will
The data transmission measured is shown to temperature display meter.
The beneficial effects of the utility model are: the power transformer can be placed by opening up in transformer high-voltage bushing
The groove of temperature sensor, and by the temperature of temperature sensor real-time detection conducting rod, come realize indirectly detection transformer around
The purpose of group temperature, avoids the defect for causing transformer life to reduce because winding temperature is excessively high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the power transformer that the utility model has transformer winding temperature display function.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and examples.
As shown in Figure 1, it includes transformer that the utility model, which has the power transformer of transformer winding temperature display function,
Bushing 1, transformer winding 2, transformer case 3, temperature sensor 4 and temperature display meter 5, temperature sensor 4 use
Shanghai Songyuan leads the temperature sensor of the WZPT-010 model of heating sensor Co., Ltd production, and temperature display meter 5 uses tall building
The thermometer of the AI-808 model of man of Men Yu power plant production.
Transformer high-voltage bushing 1 includes conducting rod 1-1, insulating layer 1-2 and insulating coating 1-3, conducting rod 1-1 and transformer
Winding 2 connects；Transformer case 3 is equipped with the mounting hole for installing temperature display meter 5, and temperature display meter 5 passes through installation
Hole is mounted on the outer surface of transformer case 3, and insulating layer 1-2 is equipped with groove in the position close to conducting rod 1-1, this groove opens up
Position be subject to temperature sensor 4 can real-time detection to conducting rod 1-1 temperature, temperature sensor 4 is placed in groove, temperature
Degree sensor 4 is connect by electric wire with temperature display meter 5, the temperature of 4 real-time detection conducting rod 1-1 of temperature sensor, and will
The data transmission measured is shown to temperature display meter 5.
After the utility model has the power transformer work of transformer winding temperature display function, due to conducting rod 1-1
Transformer winding 2 is connected, transformer winding 2 is made of copper, and has good thermal conductivity, can be the temperature inside transformer winding
Degree is conducted effectively in conducting rod 1-1, and therefore, temperature sensor 4 can obtain transformation by detecting the temperature of conducting rod 1-1
Then temperature inside device winding 2 is externally shown by temperature display meter 5.
