Power transformer is a static electrical device, is used to a certain value of the AC voltage (current) becomes the same frequency as another one or several different values of voltage (current) devices. Power transformer is one of the main equipment of power plants and substations. Transformer action is multifaceted not only can increase the voltage of the electrical energy to power the region, but also the voltage is reduced to the use of voltage levels to meet the needs of electricity. In short, boost and buck must be done by the transformer. So we know what kind of standard temperature measuring device of power transformers should press 1. Should be measured top oil thermometer (pole-mounted transformer can be downloaded); 2.1000kVA and above oil-immersed transformers, 800kVA or more oil-immersed transformer and 630kVA and above plant and dry-type transformers, the thermometer should be connected to the remote signal signal; 3. Strong oil circulation water-cooled transformers shall be provided separately in the cooler the temperature measuring device import and export; 4. When the temperature, the temperature should calculate the tube is filled with transformer oil base; 5. Provision should be dry-type transformers manufacturer, provided a temperature measuring device.

Power transformer is one of the main equipment of power plants and substations. Transformer action is multifaceted not only can increase the voltage of the electrical energy to power the region, but also the voltage is reduced to the use of voltage levels to meet the needs of electricity. In short, boost and buck must be done by the transformer. In the process of transfer of power in the power system, would have a two-part voltage and power loss, voltage loss is inversely proportional to the square of the voltage is inversely proportional to the power loss and voltage in the transportation of the same power. Use of transformers increase the voltage and reduce the power transmission loss. Transformer is made up of two wound on the same core of two or more coil windings, an alternating magnetic field by contact with press working principle of electromagnetic induction between the windings. Transformer installation location should consider ease of operation, maintenance and transport, and should choose a safe and reliable place. When using the transformer must be a reasonable selection of the transformer rated capacity. Transformer no-load operation, the required large reactive power. These reactive power to be supplied from the power supply system. If you choose the transformer capacity is too large, not only increased the initial investment, but also long-term in the transformer load or light load operation, so that the proportion of no-load losses increase, power factor reduction, network losses increase, this is neither economic nor run reasonable. Choose transformer capacity is too small, it will make a long-term transformer overload, easy to damage the equipment. Thus, the transformer rated capacity should be selected according to the needs of electricity load, should not be too large or too small

Transformer components include the body of (core, the winding, insulation, lead), transformer oil, fuel tank and cooling devices, pressure devices, protective devices (moisture, safety airways, gas relay, conservator and temperature measuring devices ) and bushing. 1. Core Core transformer in the main part of the magnetic circuit. Usually it consists of a high silicon content, thickness, respectively 0.35mm \ 0.3mm \ 0.27mm, the surface coated with insulating paint hot or cold rolled silicon steel sheet piled up. Iron legs and cross piece into two parts, legs sheathed with windings; cross-piece is closed magnetic purposes. The basic form of the core structure determined formula shell two. 2. Winding It is part of the transformer winding circuit, which is double insulated flat wire or silk bag enamelled round wire wound into.
