The distribution box is a common distribution terminal device in the field of low-voltage power supply and distribution, and the switching device, the measuring instrument, the protective electrical appliance and the auxiliary device are assembled in a closed or semi-closed metal box or on a screen to form the low-voltage distribution box.

Be provided with numerous distributor in the low pressure distribution box, these distributor often all are compact, and when outdoor stable higher, the incasement temperature increases thereupon, can be higher than outdoor stable usually, and the incasement part power accessory has self-heating phenomenon when great current is passed through in addition, and the incasement needs effective cooling to avoid causing the ageing fire hazard problem even of part because of high temperature. At present, the mode of cooling in the distribution box mainly depends on ventilation or an exhaust fan to drive the circulation of air inside and outside. However, when the outside of the cabinet is in a high-temperature environment or a high-humidity environment, the temperature and humidity inside the cabinet cannot be effectively reduced by circulating the air inside and outside the cabinet. The use of outdoor distribution box is installed with the following requirements: rain and snow prevention measures are required; grounding protection measures are required for arranging the fence; the ground feet of the moisture-proof distribution box are higher than the ground by not less than 20 cm, a wood board is laid to be used as insulation, and the distance between the bottom of the distribution box and the ground is not less than 1.2 m; an operation space not less than 70 cm is reserved in front of and behind the distribution box; the fence is provided with a caution electric shock indicator. The existing outdoor distribution box has the following defects: only has the function of heat dissipation or heat insulation. When the distribution box is used in an underground space such as an underground parking lot, the distribution box is required to have a corresponding moisture-proof function because the underground space is generally filled with moist air.

If outdoor distribution box moves under humid environment, brings the hidden danger to its safety, when the temperature is more than 30 ℃, when air relative humidity is more than 80%, then can arouse the condensation phenomenon, the condensation can cause power equipment binding post to corrode, reduce insulating properties and arouse the short circuit, causes unnecessary power failure accident and loss.

In the moist environment throughout the year, the current block terminal that has dehumidification function is generally bulky, is mostly open dehumidification, and it is little to be able to satisfy underground space, and electric quantity is not many and the moist environment throughout the year.

In addition, the dust that produces in the box is difficult to carry out effectual clearance when falling on the distribution device, and current dust collector has only carried out preliminary dust removal, and after preliminary dust removal, often more showy dust in addition stays the block terminal in, and dust removal effect is poor, has increased the danger that the block terminal used.

The gas inlet and outlet of the distribution boxes with different models are assembled after being transformed (forming windows), so that the device can be suitable for application of distribution boxes with different models.

Example 3: in embodiment 2, on the rear side of the power accessory carrying bracket 56 and the keel frame 57 near the inner wall of the box body, there is an inner rear wall 26 vertically penetrating each side wall in the box body, a vacant area 28 is formed between the inner rear wall 26 and the box body rear wall, and the front side area of the inner rear wall 26 is a power accessory area 27.

As shown in fig. 14, a series of exhaust array holes 31 are respectively formed in the inner rear wall 26, and a plugging cap 32 is respectively fitted over each exhaust array hole.

An exhaust port is provided on the rear wall of the case and an exhaust fan 29 is installed.

In use, this embodiment provides for the circulation of a cold gas stream in this region by selectively removing a portion of the containment cap 32. As can be seen from the scheme of the embodiment 1, cold air flow is introduced into the box body, so that positive pressure exists in the box body, and the cold air flow can be selectively introduced into the area where the corresponding exhaust hole is located after the partial plugging cap is selectively removed. Therefore, the present embodiment can remove the plugging cap at the rear side of the heat generating component according to the position of each heat generating component in the power accessory area, so that the cold air flow intensively flows through the area where the heat generating component is located, and the power accessory with high specific heat generation amount can be specifically and individually cooled.

Example 4: on the basis of example 3, another cooling method with continuously alternating ranges, such as the one illustrated in fig. 15 and 16, can also be used for the selective cooling scheme.
