Power distribution room intelligent monitoring system

Abstract

The invention discloses a power distribution room intelligent monitoring system comprising a shell. The shell is provided with a data conversion and acquisition circuit capable of inducing temperatureand humidity and smoke, a power supply and communication interface circuit, a blower control contact output circuit and a human-computer interaction circuit which are electrically connected and controlled by a microprocessor circuit. The lower part of the shell is fixedly provided with a fan driven by a blower through a supporting base. Working of the blower is controlled by the blower control contact output circuit. The internal end of the supporting base is fixedly provided with a supporting sleeve which sleeves the rotating shaft of the blower. The supporting base is fixedly provided witha protective cover. The temperature, humidity and smoke signals in the transformer substation can be detected in real time, and timely alarming can be performed and all the indoor ventilation fans andventilation passages can be turned off when the judgment result indicates fire of the power distribution substation or the transformer substation according to the signals so that indoor and outdoor air circulation can be prevented, indoor oxygen supply can be cut off, automatic fire extinguishing can be performed through the generated smoke and assisting fire extinguishing can also be performed when alarming is performed.

Description

Technical field [0001] The invention relates to an intelligent monitoring system for a power distribution room. Background technique [0002] At present, power distribution places such as power distribution rooms, substations, and substations, especially oil-filled equipment rooms, are very prone to fire. Therefore, monitoring systems are required. In addition to alarm devices, monitoring systems generally include ventilation and moisture prevention Cooling equipment. In order to extend the operating period of the monitoring system and save energy, these ventilation devices are equipped with controllers that control start and stop. [0003] Existing ventilation controllers are all temperature controlled, and the fan is started when the preset starting temperature is reached, and the fan is stopped when the temperature is lower than the preset stop temperature. Such a controller is very imperfect, and should also realize the function of starting and stopping the humidity fan. In ...

AI Technical Summary

Problems solved by technology

Such a controller is very imperfect, and it should also realize the function of starting and stopping the fan in humidity

In addition, for oil-filled electrical equipment, in the event of an accident such as a fire, the temperature rises. If the fan is activated for ventilation, the oxygen entering will produce a combustion-supporting effect, causing the fire to be uncontrollable or even spread, causing the accident to expand.
