Problems solved by technology

Because there are many electrical components inside the power distribution cabinet, it will generate a lot of heat when it is working. When the heat accumulates too much, it is not conducive to the work of the power distribution cabinet and will also affect the performance of the power distribution cabinet.

Embodiment 1

[0024] Such as figure 1 The ventilation mechanism of the power distribution cabinet shown includes a power distribution cabinet 1, the side of the power distribution cabinet 1 is provided with a vent, and the vent includes a plurality of ventilation holes, and the dust cover is provided on the ventilation hole 2. The limit bar 3 is also fixed on the side of the power distribution cabinet 1, the cross section of the limit bar 3 is "L" shaped, one side of the limit bar 3 is fixed on the power distribution cabinet 1, and the other One side is perpendicular to the side of the distribution cabinet 1.

[0025] The opening formed by the dustproof cover 2 and the distribution cabinet 1 is downward.

[0026] The dust-proof cover 2 includes two dust-proof sheets vertically fixed to each other, and one dust-proof sheet is vertically fixed on the side of the power distribution cabinet 1 .

[0027] Described air vent has two rows.

[0028] There are two limiting strips 3.

[0029] The ...

Embodiment 2

[0031] This embodiment is substantially the same as the embodiment 1. In order to facilitate heat dissipation, the following improvements are made on the basis of the embodiment: the dust cover 2 is arranged in an arc shape. According to the principle of air circulation, the dust-proof cover is set in an arc shape, which is more conducive to the flow of heat. Compared with the solution in Example 1, the flow of heat is faster.

Abstract

The invention discloses a ventilating mechanism of a power distribution cabinet. The ventilating mechanism of a power distribution cabinet comprises the power distribution cabinet. A ventilating opening is formed in a side surface of the power distribution cabinet and comprises a plurality of ventilating holes; a dustproof cover is arranged on the ventilating holes; a limiting strip is also fixed on the side surface of the power distribution cabinet; the cross section of the limiting strip is 'L'-shaped; a surface of the limiting strip is fixed on the power distribution cabinet; and the other surface of the limiting strip is perpendicular to the side surface of the power distribution cabinet. The ventilating mechanism of the power distribution cabinet has the advantages that the ventilating mechanism is simple in structure, facilitates dissipation of heat in the power distribution cabinet, and can be waterproof and dustproof; and the ventilating holes are not easily blocked.

Description

technical field [0001] The invention relates to a ventilation mechanism, in particular to a ventilation mechanism of a power distribution cabinet. Background technique [0002] The power distribution cabinet is divided into power distribution box, metering box and lighting distribution box, which is the final equipment of the power distribution system. The distribution box is used in the occasions where the load is relatively scattered and the circuit is small. It distributes the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. Due to the many properties of the power distribution cabinet, its importance is determined. Because there are many electrical components inside the power distribution cabinet, it will generate a lot of heat when it is working. When the heat accumulates too much, it is not conducive to the work of the power distribution cabinet, and it will also affect the performance of the power distribution c...
