Power transformer intelligent control device

Abstract

The invention discloses an intelligent control device for a power transformer. The intelligent control device comprises a transformer and a plurality of contactors correspondingly connected with output lines of the transformer, wherein the contactors are connected with an intelligent controller; the intelligent controller has a shell; a master control circuit board, a driving circuit, a liquid crystal display (LCD) and a control panel are arranged in the shell; the master control circuit board is respectively connected with the driving circuit, the LCD and the control panel through signal transmission lines; the signal input end of the master control circuit board is connected with a monitoring mechanism; and the driving circuit is connected in series with a power circuit of a contactor coil. The intelligent control device can prevent electric leakage and monitor and control the temperature and load of the transformer in real time, has independent subcircuits, is energy-saving and environment-friendly, avoids an adverse effect caused by wide-range power failure, and can timely take measures of cutting off power and reducing the load according to the conditions of overhigh temperature, overcurrent and electric leakage of the transformer so as to ensure the safe and stable operation of a power grid.

Description

technical field [0001] The invention relates to the technical field of power equipment monitoring and management, in particular to an intelligent management and control device for power transformers. Background technique [0002] At present, in the construction of the county-level power grid, not only the complex monitoring, operation and maintenance building facilities and large-scale workforce are required for the supporting system of the main transformer, but also the corresponding distribution equipment and on-duty maintenance are required for each distribution transformer. personnel. As a result, a large amount of manpower and material resources have been invested and occupied. If the conditions are harsh in remote mountainous areas, the working conditions of the stationed on-duty personnel are also quite difficult; secondly, if leakage, short circuit, etc. Under technical conditions, it is necessary to shut down the transformers in this area for maintenance, causing l...
