Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, and in particular relates to a low-voltage switch cabinet. Background Art

[0002] MNS low-voltage switchgear is a withdrawable complete set of switchgear, which is widely used in various power generation and distribution systems due to its superior performance. Usually, the MNS low-voltage switchgear is divided into multiple functional compartments such as power distribution cabinet, lighting distribution cabinet, metering cabinet, etc. through partition plates, which can facilitate centralized control while dividing multiple functional areas without interfering with each other.

[0003] During the use of the MNS low-voltage switchgear, each functional area needs to be kept ventilated. However, dust is inevitably carried in the air. When the electrical components are in normal operation, dust is often easily attached to the surface of the electrical components, causing the electrical components to be in a high temperature state, thereby affecting the service life of the electrical components. There are many electrical components in the switchgear, which makes it difficult to clean.

[0004] In order to solve the hidden danger caused by dust entering the switch cabinet, a patent application with authorization announcement number CN212543059U discloses an MNS type low-voltage distribution cabinet, which is equipped with a dust isolation frame to block the pollution in the air and discharge the dust with the induced draft fan; at the same time, dual heat dissipation is carried out through a thermostat and a louver to ensure that the inside of the switch cabinet is in a suitable temperature state.

[0005] However, since the dust isolation frame and the electrical box body are in a drawer-type overlapping structure, the dust isolation frame needs to be pushed outward when cleaning and maintaining the inside of the electrical box body, and the area of ​​the dust isolation frame is larger than the electrical box body, a space distance larger than the electrical box body needs to be reserved to push the dust isolation frame open. Such a structure results in a larger footprint of the distribution cabinet.

[0006] Therefore, there is an urgent need for a low-voltage switch cabinet that can reduce dust from entering the cabinet, facilitate heat dissipation and occupy a small area. Utility Model Content

[0007] The purpose of the present invention is to solve at least the above-mentioned drawbacks and provide advantages which will be described later.

[0008] In order to achieve these purposes and other advantages of the utility model, a low-voltage switch cabinet is provided, including: a switch cabinet body and a dust cover.

[0009] Wherein, the side wall of the switch cabinet body is provided with a plurality of first ventilation openings.

[0010] The dustproof cover comprises a dustproof frame, a dustproof plate, a dustproof sheet and a plurality of dust-blocking sheets.

[0011] The dust isolation frame is a frame structure with two ends opened, and a first end of the dust isolation frame is connected to the switch cabinet body.

[0012] The dust isolation plate is connected to the second end of the dust isolation frame, and a plurality of second ventilation openings are formed on the dust isolation plate.

[0013] The dust isolation sheet is connected to one end of the dust isolation plate that is connected to the dust isolation frame.

[0014] A plurality of the dust shielding sheets are connected to one end of the dust shielding plate away from the dust shielding frame, and a plurality of the dust shielding sheets are respectively connected to a plurality of the second vents to form a grille structure with the opening facing downward.

[0015] In the above scheme, in the low-voltage switch cabinet of the utility model, a dust cover is connected to the outside of the switch cabinet body to effectively reduce dust from entering the inside of the switch cabinet body, thereby preventing dust from adhering to the surface of the electrical components.

[0016] Secondly, in the low-voltage switch cabinet of the utility model, the second ventilation opening of the dust cover and the first ventilation opening of the switch cabinet body ensure that the switch cabinet body is in a ventilated state, so that the heat generated by the switch cabinet body during operation can be dissipated in time.

[0017] Preferably, the dust isolation frame and the dust isolation plate are connected to form a accommodating space; a fan is provided in the accommodating space, and the fan faces the first vent.

[0018] An air outlet is provided on any side wall of the switch cabinet body, and the air outlet is connected to a wind shield; the wind shield is composed of a plurality of wind shields connected in parallel, and the wind shields are connected to the outer side walls of the switch cabinet body through a rotating shaft. The gas in the switch cabinet body blows up the wind shields and then is discharged outward through the gaps between the wind shields.

[0019] In the above scheme, air is further introduced into the interior of the switch cabinet body through the fan to accelerate the heat dissipation speed of the switch cabinet body. At the same time, the wind shield is connected to the outer wall of the switch cabinet body through a rotating shaft. When exhausting air, the wind shield blows air upward to dissipate the hot air. At other times, it is in a closed state, which can not only effectively isolate dust from entering the interior of the switch cabinet body through the air outlet, but also reduce the noise generated by the operation of the switch cabinet body from being transmitted to the outside.

[0020] Preferably, the low-voltage switch cabinet further comprises a lifting structure; the lifting structure is connected to the side wall of the switch cabinet body, and the lifting direction of the lifting structure is the height direction of the switch cabinet body.

[0021] The dust cover is connected to the lifting structure, and when the lifting structure is in a raised state, the first vent is aligned with the second vent; when the lifting structure is in a lowered state, the first vent is staggered with the second vent.

[0022] In the above scheme, the height of the dust cover is adjusted through the lifting structure, and then the relative positions of the first vent and the second vent are adjusted. When the lifting structure is in a raised state, the first vent and the second vent are aligned, which is beneficial for external air to be transported to the interior of the switch cabinet body through the first vent and the second vent; when the lifting structure is in a lowered state, the positions of the first vent and the second vent are staggered, thereby avoiding moisture from entering the first vent through the second vent in rainy weather.

[0023] Preferably, a plurality of rotating clips are provided at one end of the dust-shielding plate connected to the dust-shielding frame, and one end of the rotating clip is connected to the dust-shielding plate via a rotating shaft.

[0026] In the above scheme, the temperature state inside the switch cabinet body can be obtained in real time through the temperature sensor, and the controller can be used to adjust the switch of the fan in time to achieve the effect of timely heat dissipation.

[0027] Preferably, the dust-proof sheet is water-absorbing filter cotton.

[0029] Preferably, at least four rotating clips are provided, and the rotating clips are respectively connected to four sides of the dust shielding plate.

[0030] In the above solution, the dust-isolating sheet is stably connected to the dust-isolating plate by arranging rotating clips on the four sides of the dust-isolating plate.

[0034] In addition, in the low-voltage switch cabinet of the present invention, air is further introduced into the interior of the switch cabinet body through a fan to accelerate the heat dissipation speed of the switch cabinet body. At the same time, the wind shield is connected to the outer wall of the switch cabinet body through a rotating shaft. When exhausting air, the wind shield blows air upward to dissipate the hot air. At other times, it is in a closed state, which can not only effectively isolate dust from entering the interior of the switch cabinet body through the air outlet, but also reduce the noise generated by the operation of the switch cabinet body from being transmitted to the outside.
