摘要
automatic monitoring and control system of the gaseous atmosphere in electric power transformers with liquid insulators, with supervision and remote alarms of the operating conditions. It is a system capable of continuously and automatically monitoring and controlling the inert gas pressure in the gas mattress (3) contained in an electric power transformer (i) in order to keep it stable and higher than the current. atmospheric pressure. The whole system is electronically controlled, when the pressure rises above a preset value the gas is sucked into a vacuum chamber (45) connected to a compressor (47), and when it decreases below a preset value, It is injected by the inert gas accumulator (52) through the pressure regulating valve (50) which injects it with a constant and limited pressure, increasing it. The system monitors through a programmable logic controller (28) the pressure, temperature and humidity of the inert gas, as well as the temperature of the liquid insulator (2) and the electrical quantities demanded by the transformer (i). The system is supervised by a management center (33) that communicates through the global communication network (31) to receive monitored, control and alarm information, and can also manually operate the system remotely.
