Technical Field
The utility model belongs to the technical field of power testing, and particularly relates to a temperature monitoring device of a voltage transformer.
Background
A voltage transformer (Voltage Transformer, also called Potential Transformer or Voltage Transformer) is a device for measuring the voltage of a high voltage transmission line. The high voltage is reduced to the range which can be safely measured, so that necessary signals are provided for the measurement and protection of the power system. The voltage transformer is usually composed of a high-voltage side winding and a low-voltage side winding, wherein the high-voltage side winding is connected with a power grid, and the low-voltage side winding is connected with equipment such as a measuring instrument or a relay. When the high-voltage side winding is connected to the power grid, even small voltage changes can generate corresponding voltage changes, so that a larger transformer effect is generated on the low-voltage side, and the voltage of the high-voltage side is reduced to be within a safe measurement range. Voltage transformers are generally of different designs, for example, shell-and-shell-free, and are often of the pointer type, digital type, combined type, etc. Pointer voltage transformers typically display voltage through a mechanical indicator, while digital voltage transformers display voltage values through a digital display screen. The combined voltage transformer combines a plurality of components together to realize a plurality of functions. The voltage transformer is widely applied to the power system, and has the main effects of reducing the high voltage in the high-voltage transmission line to the safety measurement range, so that the electric energy quality and the stable operation of the power system can be ensured, and necessary signals can be provided for the aspects of protection, control and the like of the power system. Because the high-voltage side of the voltage transformer needs to be connected to a high-voltage power grid, larger induction current can be generated in the voltage transformer, and in the working process, once a line breaks down, local overheating can be caused, so that electric accidents such as fire disaster and the like can occur. Therefore, there is a need to design a temperature monitoring device for a voltage transformer to solve the above-mentioned problems.
