Abstract

The invention discloses a transformer temperature controller and a control method. The transformer temperature controller comprises a data fusion unit, an autonomous control unit, an adaptive protection unit, a human-computer interaction unit and a communication unit; the data fusion unit, the adaptive protection unit, the human-computer interaction unit and the communication unit are all connected with the autonomous control unit; and both the human-computer interaction unit and the communication unit are connected with the data fusion unit. According to the transformer temperature controllerprovided by the invention, reliable and accurate real-time monitoring on parameter data affecting the change of a transformer temperature and fault diagnosis and protection on a cooling device can beimplemented. By combining the control method, the transformer temperature is controlled to be stable in a temperature range required by transformer insulation, so that high efficiency, energy savingand general application are achieved, operation performance of a transformer is enhanced, and the service life is prolonged; and the transformer temperature controller and the control method are goodin using effect and convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of transformer temperature control, and in particular relates to a transformer temperature controller and a control method. Background technique [0002] my country's definition of smart grid is based on a strong grid, supported by a communication information platform, and intelligently controlled to achieve a modern grid that is strong, reliable, cost-effective, clean, environmentally friendly, transparent, open, and friendly. The power transformer is an important equipment of the smart grid, and the operating temperature of the transformer is a key factor that restricts the load of the transformer and affects the life of the transformer. According to the analysis of the annual statistics of transformer operation accidents by the State Grid Corporation of China, transformer decommissioning due to excessive temperature rise accounts for a large proportion. [0003] In the "Transformer" magazine (July 2018 i...
