The intelligent air inlet device can meet the requirement of substation operation and maintenance on intelligent management level, and is simple to operate, reliable to run, low in cost, practical and efficient.

Description

[0001] Technical field: [0002] The invention relates to an intelligent air inlet device for a high-voltage room, which belongs to the field of operation and maintenance of power system transformation. Background technique: [0003] At present, the air inlet design of the existing exhaust system of the high-pressure room of the substation cannot meet the requirements of the high-voltage room for rain, dust, and small animals. Some air inlets are fixed shutters, and because of the large gap, it is very easy to induce small animal accidents in winter. In addition, the dust and sundries in the air will be sucked into the high-pressure chamber together, resulting in more dust in the room. For a long time, it will cause serious dust accumulation on the porcelain bottles and porcelain columns of open equipment, and discharge flashover will seriously affect the safe and stable operation of high-voltage equipment. The exhaust and heat dissipation efficiency of the high-pressure ro...

Problems solved by technology

[0003] At present, the air inlet design of the existing substation high-pressure room exhaust system cannot meet the requirements of high-pressure room rainproof, dustproof, and small animal prevention

Some air inlets are fixed shutters, because of the large gap, it is very easy to induce small animal accidents in winter

In addition, the dust and sundries in the air will be sucked into the high-pressure chamber together, resulting in more dust in the room, which will cause serious dust accumulation on the porcelain bottles and porcelain columns of open equipment for a long time, and discharge flashover will seriously affect the safe and stable operation of high-voltage equipment.

The exhaust and heat dissipation efficiency of the high-pressure room is low, and the room temperature remains high; the working environment of the fan is harsh, resulting in a high maintenance rate

In some substations, the vents of the high-voltage room are equipped with dust removal filters, but due to unreasonable design, it is difficult to disassemble and clean them, causing dirt to accumulate and block the filter, greatly reducing the air intake, resulting in low air flow in the high-pressure room and poor heat dissipation efficiency; , the fan is prone to heat when it runs continuously for a long time, resulting in aging damage and greatly increasing the maintenance rate

In winter, rain and snow entered the high-voltage room through the air inlet / exhaust port in some substation high-voltage rooms, resulting in vicious accidents of power outages for high-voltage equipment, which seriously affected the safe and stable operation of equipment and the reliability of power supply.

All the fans in the substation are manually turned on when the personnel arrive at the station at high temperature, which is time-consuming and laborious, and the level of intelligence is low; in addition, when the temperature load is low in the morning and evening, if the exhaust device continues to operate, a large amount of station electricity will be wasted and production costs will be increased.
