Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and more specifically, to a moisture-proof high- and low-voltage switch cabinet and a use method thereof. Background Art

[0002] High and low voltage switchgear is a kind of equipment used to control, protect and distribute electric energy in power systems. It is divided into high voltage switchgear (usually 3kV and above) and low voltage switchgear (usually below 1kV) according to the voltage level. The internal structure of the switchgear is complex and contains multiple electrical components such as circuit breakers, disconnectors, contactors, relays, etc.

[0003] Referring to the Chinese invention patent, the publication number is: CN118336550B, and the name is: A high and low voltage switch cabinet with heat dissipation and moisture-proof functions. The invention patent sets a dispersion mechanism in the mezzanine space. The dispersion mechanism includes dispersion plates arranged on the upper and lower sides of the mezzanine space, and the dispersion plates are installed on the first shell and the second shell. A plurality of dispersion holes are opened in the dispersion plate. When the air exhausted from the dehumidifier passes through the dispersion holes, the dry air is dispersed so that the air fills the entire mezzanine space. On the one hand, the temperature of the entire cabinet is increased to avoid condensation caused by contact between the external air and the cold cabinet. On the other hand, the temperature of the cabinet is balanced with that of the internal electrical equipment to reduce the temperature difference.

[0004] The high and low voltage switchgear with heat dissipation and moisture-proof functions is provided with a dispersion plate component in the interlayer to ensure uniform circulation of hot air, which can improve the dehumidification efficiency and moisture-proof effect. However, when used in a dusty environment, if the dispersion plate is blocked, the following problems may occur:

[0005] 1. Blocking will destroy the airflow pattern in the interlayer, resulting in uneven humidity distribution. The areas not affected by the hot air will maintain a higher humidity level, and even condensation will occur, which will affect the overall moisture-proof effect.

[0006] 2. Since the hot air cannot pass through the blocked area normally, the heat accumulates there and the temperature in the nearby area is high. Once the hot air encounters a colder surface (such as the switch cabinet casing or internal components), condensation water is easily formed, which is very dangerous for electrical equipment and may cause short circuits or other faults.

[0007] 3. The airflow blockage caused by blocking will form a moisture-proof "blind spot" in the interlayer, that is, some areas cannot be effectively dried. In the long run, it may cause corrosion, mildew and other problems, seriously affecting the life and safety of the equipment.

[0008] Therefore, in order to ensure good moisture-proof effect, it is necessary to ensure that the dispersion plate is unobstructed and prevent the occurrence of blockage. Summary of the invention

[0009] The present invention provides a moisture-proof high and low voltage switch cabinet and a method of using the same, and aims to solve the problem that when the existing high and low voltage switch cabinets with heat dissipation and moisture-proof functions are used in dusty environments, the moisture-proof effect is affected because the dispersion plate is blocked by dust.

[0026] The beneficial effects of the present invention are:

[0027] The present invention prevents dust from accumulating with dry gas at the orifice plate to cause blockage under the premise of setting up a group of dehumidifiers, so that the dry gas can flow normally and the temperature is uniform in each small compartment, effectively solving the problem of dust blocking the small compartment and causing airflow obstruction to form a moisture-proof "blind spot", thereby ensuring the overall moisture-proof effect.

[0028] When the dispersion mechanism of the present invention is an arc-shaped dispersion plate, there is no need to set up a dust filter assembly, a cleaning mechanism and a collecting seat. The filtered dust is automatically collected to the dust collecting plates on both sides through the arc-shaped orifice plate, collected through the dust collecting trough, and the dust inside the dust collecting trough is extracted out through the dust extraction seat at one end. This solution has low cost and good dust removal and anti-blocking effects and is suitable for use in moderate dust environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] It should be noted that the layers of cleaning cloth 821 are adhered together by adhesive. To facilitate detachment, the edges of the cleaning cloth 821 may not be coated with adhesive.

[0054] Furthermore, an elastic member 946 is fixedly connected between one end of the slider 944 and the inner wall of the slide groove 943, a slot 947 is provided at the bottom of the slider 944, an insert block 948 is movably provided inside the fixed block 942, and the top of the insert block 948 is movably connected to the slot 947, and a driver is installed inside the mounting box 941, and the driver is used to drive the insert block 948 to move up and down.

[0055] It should be noted that multiple groups of slots 947 are provided, and the insert block 948 is connected to one group of slots 947, so that the slider 944 gradually approaches the cleaning block 82.

A dust extraction port 621 is provided at one end of the dust extraction seat 62, and the dust extraction seat 62 extracts dust from the dust collecting groove 613 through the dust extraction port 621.

[0061] It should be noted that the dust extraction seat 62 is connected to an external vacuum pump to extract the dust inside the dust collecting tank 613.

[0062] In this embodiment, the implementation scenario is specifically as follows: when the dispersion mechanism 6 is an arc-shaped dispersion plate 61, there is no need to set up a dust filter assembly 7, a cleaning mechanism 8 and a collecting seat 9. The filtered dust is automatically collected on the dust collecting plates 612 on both sides through the arc-shaped orifice plate 611, and collected through the dust collecting groove 613. The dust inside the dust collecting groove 613 is extracted out through the dust extraction seat 62 at one end.

When the dispersion mechanism 6 is a straight plate component, a dust filter assembly 7, a cleaning mechanism 8 and a collecting seat 9 are arranged on the top. Dust is collected through the arc-shaped dust filter assembly 7 and scraped clean by the cleaning block 82 on the arc-shaped bottom surface. The inlet and outlet 92 facilitates the cleaning block 82 to pass through and move to the top of the collecting groove 91, and the cleaning block 82 is connected to the connecting port 9. 3 is convenient for collecting waste water from the dehumidifier 13, and dust falls into the collecting tank 91 and combines with the waste water to prevent dust from flying. Dust in the muddy state is not easy to re-enter the air circulation system, which helps to maintain a dry environment in the interlayer chamber 5 and further enhances the moisture-proof effect. The linear drive component 85 drives the cleaning block 82 to extend into the collecting tank 91, and the bottom of the cleaning block 82 is cleaned by the waste water in the collecting tank 91. When the waste water in the collecting tank 91 is insufficient, the driver in the installation box 941 drives the plug-in block 948 to move up and down, so that the plug-in block 948 is connected to one of the groups of slots 947, so that the slider 944 is gradually approached to the cleaning block 82, and several layers of cleaning cloth 821 are separated layer by layer, ensuring that the cleaning block 82 has a better cleaning effect.
