Description
Technical Field
The invention relates to the technical field of condensation removal, in particular to an intelligent air quantity adaptive condensation removal cooling device and method for an electric power ring main unit.
Background
The condensation problem is common in outdoor metal boxes, and the basic principle of the formation is as follows: the air contains a certain amount of water vapor, and under certain pressure and temperature conditions, the maximum water vapor mass which can be contained in the unit volume of air is the saturated humidity of the air. During the daytime, as the temperature increases, the saturation humidity of the air increases; at night, as the temperature decreases, the saturation humidity of the air decreases. When the humidity in the air is high and exceeds the saturation humidity of the air, relatively static water vapor can be condensed at the lower temperature of the box body, so that condensation is generated. Humidity, temperature and static and dynamic properties of water vapor are decisive factors for the generation of condensation.
In the electric power ring main unit of the national network company, the currently adopted anti-condensation measures mainly comprise:
1. the dehumidifying equipment is added to reduce the air humidity;
2. heating equipment is added to raise the temperature in the cabinet;
3. carrying out ventilation modification on the electric ring main unit;
4. plugging reserved holes at the bottom of the electric power ring main unit, and preventing water vapor in a cable well from entering the electric power ring main unit;
5. a bottom plate is arranged at the bottom of the electric power ring main unit to isolate a cable channel, so that water vapor in the cable channel is prevented from entering the electric power ring main unit;
6. isolation electric power looped netowrk cabinet basis and cable channel prevent ponding in the cable channel inflow in the cabinet basis.
In the above-mentioned anti-condensation measure 6, the dehumidifying device and the heating device are additionally installed in the measures 1 and 2, and the following drawbacks exist for both the new cabinet body and the stock cabinet body: (1) The action area is limited, the more the intervals of the cabinet bodies are, the more the equipment quantity to be installed is, and if only one piece of equipment is installed, the condensation removal purpose cannot be realized; (2) The equipment is large in size, although the current dehumidification equipment and heating equipment are miniaturized, the dehumidification equipment and the heating equipment are contained in a part of secondary chambers of the electric ring main unit and all operating mechanism intervals; (3) The power is high, although the power of a single dehumidifying device and the heating device is smaller, when a plurality of devices work synchronously, the power is higher, and the safety of PT devices can be threatened; (4) easy damage and short service life.
The effect of ventilation transformation to the electric power ring main unit in the measure 3 is limited, because the transformation to the electric power ring main unit is basically limited to the cabinet body shell, the ventilation effect is difficult to improve the condensation condition in each relatively closed interval, and because the external ventilation is carried out, impurities in the air outside the cabinet body are easy to bring into the electric power ring main unit, and the running environment of internal equipment is deteriorated.
Measures 4-6 have a certain effect on the anti-condensation of the newly-built cabinet body, however, once the original measures at the bottom of the cabinet body are destroyed due to the fact that the cabinet body is maintained or the cabinet body is increased to be out of line, the effect is difficult to ensure, and for the stored power ring main unit, the construction amount is large, the construction is complex, and power failure operation is needed; in addition, to the region that air humidity is great, only keep apart electric power looped netowrk cabinet bottom's steam, can't realize removing the purpose of condensation at all.
Although various measures for removing condensation of the electric power ring main unit are proposed at present, the problem is not solved effectively for many years all the time, and the phenomenon of condensation is particularly common in areas with developed water systems, abundant rainfall and clear four seasons, such as Jiang Zhe Hu. The occurrence of condensation can not only lead to the mistaken connection of the inner terminal of the cabinet and the rust of metal equipment and architecture, but also reduce the insulativity, mechanical strength and operability of the equipment, finally cause accidents such as tripping, creepage or flashover, and the like, and influence the safe operation of power production and the normal production and life of people. Therefore, developing an intelligent air volume adaptive dew-removing cooling device for an electric power ring main unit has very important practical significance.

s3, the ventilation is blown to each air quantity adapting pipe (14) through a first pipeline (25), a second pipeline (26) and an air guide pipe (13), the air speed and the air quantity at the air opening of each air quantity adapting system (23) are regulated to be consistent through regulating an air quantity regulating valve (15) arranged at the air quantity adapting pipe (14), and the air direction is regulated at multiple angles through regulating a universal air pipe (16), so that key equipment in a switch cabinet is aligned, the ventilation outlet is in a row shape through arranging a duckbill type air opening (17), and the aim of removing dew and cooling in the switch cabinet is fulfilled;
s4, controlling the start and stop of 2 groups of overlapped combined micro fans of the integrated central breathing machine (6) through various fan control modes set by the intelligent controller, wherein each group comprises 2 micro fans: under normal conditions, 2 micro fans work in turn, and after the combination 1 is started for five minutes, the combination is stopped and started for 2 minutes at the same time; and 5, simultaneously stopping the air heating dryer of the 2 groups of overlapped combined micro fans for five minutes, and heating the silica gel to discharge water.
