specific Embodiment approach 1

[0014] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, a ventilated and dustproof distribution box described in this embodiment, which includes a housing 1 and a cabinet door 2; one side of the housing 1 is provided with an opening, and the cabinet door 2 is connected to the housing through a connecting shaft the open side of 1;

[0015] It also includes N filter screens 6 and an air exhaust device 9; the inside of the housing 1 is provided with an air inlet passage, the inlet 7 of the air inlet passage is located on a wall of the housing 1, and the outlet 5 of the air inlet passage is located inside the housing 1; The N filter screens 6 are all located on the air inlet channel; the N filter screens 6 are all used to filter the air in the air intake channel;

[0016] Described air extraction device 9 comprises air extraction device shell, M fixing devices 10, rebound device 11, two baffle plates 12 and cooling fan 13; and the No. 2...

specific Embodiment approach 2

[0019] Specific embodiment 2: This embodiment is to further limit the ventilated and dust-proof distribution box described in specific embodiment 1. In this embodiment, it also includes a gasket 4, which is used to increase the housing 1 and the airtightness of the cabinet door 2.

specific Embodiment approach 3

[0020] Specific embodiment three: This embodiment is to further limit the ventilation and dustproof distribution box described in specific embodiment one or two. In this embodiment, N filter screen slots are arranged on the cabinet door 2, N The positions of the filter screen slots correspond to the positions of the N filter screens 6 respectively. The setting of the filter screen groove can prevent the filter screen 6 from affecting the airtightness of the housing 1 and the cabinet door 2 .

Abstract

The invention relates to a distribution cabinet, in particular to a ventilated dustproof distribution cabinet and aims to solve the problems that internal ventilation of the distribution cabinet is poor and long-term running of components results in dustiness. A housing is internally provided with an intake passage, an entry of the intake passage is located in the housing, and an exit of the intake passage is located in the housing; all strainers are located on the intake passage; a suction device includes a first mounting chamber and a second mounting chamber as well as a partition having an air vent, and a cooling fan is fixed to the second mounting chamber; wherein one retainer is fixed to the first mounting chamber, one end of a fixing device is fixed to one retainer, and the other end of the fixing device passes through the other retainer and is fixed to a retainer; two ends of a resilient device are fixed to two retainers, respectively; the first mounting chamber is provided with an air outlet, and the second mounting chamber is internally provided with an intake hole; the housing is also provided with an air outlet, and one end of the air outlet of the suction device is fixed to an air inlet in the housing. The distribution cabinet has the advantages of good ventilation effect and good dust proofing effect and is applicable to low-voltage distribution for power systems.

Description

technical field [0001] The invention relates to a distribution box, in particular to a highly efficient ventilation and dustproof distribution box. Background technique [0002] Distribution box is to assemble switchgear, measuring instrument, protective device and auxiliary equipment in closed or semiclosed metal cabinet or on screen width according to electrical wiring requirements, and its layout should meet the requirements of normal operation of power system. There are a large number of components installed in the distribution box, and the continuous high-speed operation of the components will cause a large amount of heat to accumulate in the distribution box. When the temperature inside the distribution box is too high, the components will not work normally, or even burn the components. Therefore, the distribution box must be equipped with a ventilation device, but the traditional ventilation device cannot prevent dust from entering the interior of the distribution box...
