Abstract

A transformer cooling system automatic alternation switching control device includes a minitype industrial control computer, a remote alarm module, a plurality of monitoring control modules, one end of which is connected with the minitype industrial control computer through the R485 field bus, and the other end is connected with the cooling system control logic and the indicating circuit; the remote alarm module is connected with the cooling system control logic and the indicating circuit. The invention has the beneficial effect of solving the energy waste caused by the out of time device alternation and pointless input, avoiding the long operating state of the motor, advancing the operating service life of the motor, reducing the failure rate, having high automaticity, which is suitable for the temperature fluctuation of the four seasons and the lower load fluctuation, saving the energy and reducing the energy consumption.

Description

(1) Technical field [0001] The invention belongs to a transformer cooling system, in particular to an automatic rotation switching control device for a transformer cooling system. (2) Background technology [0002] With the gradual deepening of the reform of the economic system and the rapid development of the regional economy, the large-scale construction of various living communities, schools, enterprises and institutions has greatly promoted the development of the electric power industry, and at the same time intensified the backward power supply equipment and management models. The contradiction between the rapid development of social economy has put forward new requirements for power supply equipment, power supply quality, and power supply reliability. At present, the cooling methods and functions of domestic large-scale power transformers are not very perfect, and cannot adapt to the requirements of comprehensive automation of substations, temperature changes in four s...
