Intelligent ventilation control device for substation with flame retardant and fire extinguishing functions

Abstract

The invention discloses a transformer substation intelligent ventilation control device with the inflaming retarding and fire extinguishing functions. The transformer substation intelligent ventilation control device comprises a shell; the shell is provided with a data conversion and acquisition circuit, a power source, a communication interface circuit, a draught fan control contact output circuit and a man-machine interaction circuit; the data acquisition circuit, the power source and the communication interface circuit are electrically connected together, are controlled by a microprocessor circuit and can sense temperature, humidity and smog; the lower portion of the shell is fixedly provided with a fan driven by a draught fan through a supporting base; the work of the draught fan is controlled through the draught fan control contact output circuit; the inner end of the supporting base is fixedly provided with a supporting sleeve arranged on a draught fan rotary shaft in a sleeving mode; the supporting base is fixedly provided with a protective shield; the temperature, humidity and smog signals in a transformer substation can be detected in real time; when it is judged that a fire occurs in the transformer substation according to the signals, an alarm is given in time, ventilation fans and ventilation channels of the transformer substation are closed, so that circulation of inner and outer air of the transformer substation is blocked, oxygen supply in the transformer substation is cut off, and the fire is automatically extinguished through the generated smoke.

Description

technical field [0001] The invention relates to an intelligent ventilation control device for a substation with flame retardant and fire extinguishing functions. Background technique [0002] At present, industrial places such as substations and substations, especially equipment places such as oil-filled equipment rooms, need to be equipped with ventilation equipment. In order to prolong the operation period of ventilation equipment and save energy, these ventilation equipment are equipped with automatic start and stop controllers. [0003] Existing ventilation controllers are all temperature-controlled, the fan is started when the preset starting temperature is reached, and the fan is stopped when the preset stop temperature is lower than the preset stop temperature. 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 ...

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.
