Description

An air conditioner for indoor electrical equipment

technical field

The utility model relates to the technical field of substation equipment, in particular to an air conditioner for indoor electrical equipment.

Background technique

In a substation, because most of the electrical equipment generates a lot of heat, it is an indispensable process to discharge the heat in the substation machine room. Generally, it is realized by opening a hole in the substation machine room and installing a fan on the hole, but The existing fan is still in working state even when the machine room does not need to cool down, and the operation can only be ended by manually shutting down, which wastes a lot of electric energy.

At present, the temperature control of most substations adopts centrifugal fans for internal exhaust, and at the same time uses air conditioners to assist cooling. However, when the air conditioner cools down the substation, it causes the accumulation of indoor toxic gases and equipment condensation. In order to solve the ventilation and condensation problems, fans, heating rods or dehumidifiers have to be turned on. However, the strong wind of the fan produces a large amount of air vortex or turbulence in the space around the electrical equipment. This part of the air either collides with the east or west in the space, or rotates in situ. The hot body contributes to the increase of the indoor temperature. Moreover, the strong wind also brings a large amount of dust and harmful substances from the outside into the room, forming scales on the ground and equipment surfaces, corroding electrical equipment and even forming discharge channels, which poses a potential danger to the safety of power supply. The sudden drop of the temperature caused the condensation of the equipment. In order to solve the problem of equipment condensation, the heating rod or dehumidifier had to be turned on. This repeated investment, mutual offset and loss between the equipment, single function and low efficiency caused a lot of energy consumption. Loss can not completely solve the problem. In addition, because the existing ventilation and cooling methods cause turbulent or mixed flow of airflow in the entire substation interior space, the efficiency of ventilation and cooling is low, resulting in a large amount of energy loss and greater noise pollution to the surrounding environment.

CN201020689062.5 discloses a new type of automatic cooling substation, which includes a substation cabinet, and is characterized in that: the cabinet is provided with a single-chip control module, a fan, and a temperature sensor, and the surface of the cabinet is provided with solar cells. The solar battery is connected with the single-chip microcomputer control module, and is used to supply power for the single-chip microcomputer control module and the fan. Its disadvantages are: 1) The strong wind of the fan produces a large amount of air eddy or turbulence in the space around the electrical equipment, which not only cannot discharge the carried heat to the outside, but becomes a heat storage body instead, which contributes to the increase of the indoor temperature . 2) The strong wind also brings a large amount of dust and harmful substances from the outside into the room, forming scales on the ground and equipment surfaces, corroding electrical equipment and even forming discharge channels, which poses a potential danger to power supply safety. 3) Unable to utilize natural wind power, wasting energy.
