Description

Technical Field

[0001] The present application relates to the technical field of overvoltage suppression cabinets, and in particular to a moisture-proof overvoltage suppression cabinet. Background Art

[0002] The voltage transformer cabinet adopts a combined structure, and can be equipped with different numbers and types of PTs according to specific projects. It adopts a removable metal armored structure as a whole and is equipped with a large observation window on the panel, so that the operation of the cabinet can be observed at any time. Each PT is equipped with a separate trolley, and its primary and secondary circuits adopt a tap structure to achieve the separation of the primary and secondary chambers. The overall appearance is beautiful and reliable, and it can be pulled out for maintenance under power.

[0003] In the overvoltage suppression cabinet industry, in the prior art, it is necessary to provide a certain degree of moisture-proof protection. The existing moisture-proof overvoltage suppression cabinet is not convenient for moisture-proof and ventilation, and prevents water vapor and moisture from penetrating into the cabinet body. It is not convenient to filter dust in the air during ventilation, and it is not convenient to lower the temperature of the air, and it is impossible to ensure the dryness of the internal components, electrical components and air of the cabinet body, so as to make it more moisture-proof. A Chinese patent (Announcement No.: CN 209282614 U) discloses a moisture-proof overvoltage printed cabinet, which solves the problem that it is not convenient to play the role of moisture-proof and ventilation, prevents water vapor and moisture from penetrating into the cabinet body, and is not convenient to filter dust in the air during ventilation.

[0004] Since the screen needs to be replaced after long-term use to prevent dust from clogging the screen holes, the protective box in the above document is in a sealed state, which makes it inconvenient for the staff to replace the screen, waterproof breathable membrane and heat sink. When the screen is blocked, the temperature in the cabinet will not be easily dissipated, making the ventilation of the suppression cabinet poor. In addition, the silicone pad is fixed at the lower end of the support plate. After long-term use, the silicone pad and the drying strip will reduce their own adsorption and affect the moisture resistance inside the suppression cabinet. Utility Model Content

Three support plates 3 are fixed to the rear wall of the inner cavity of the voltage suppression cabinet main body 1, and two protection boxes 4 are fixed to the left and right walls of the inner cavity of the support plate 3. A screen 51, a waterproof breathable membrane 52, and a heat sink 53 are respectively clamped on the inner side of the protection box 4. A silicone pad 54 is provided at the lower end of the support plate 3, and a plurality of drying strips 55 are fixed at the lower end of the silicone pad 54. Replacement components are provided at the front ends of the two protection boxes 4 and the lower ends of the three support plates 3.

[0032] Among them, a card slot is opened at the bottom of the inner cavity of the protection box 4, and the screen 51, the waterproof breathable membrane 52, and the heat sink 53 are all connected to the inner side of the card slot, so that the screen 51, the waterproof breathable membrane 52, and the heat sink 53 can be connected to the inside of the protection box 4, and the opposite side of the two screens 51 is fixed to the opposite side of the two waterproof breathable membranes 52, and the opposite side of the two waterproof breathable membranes 52 is fixed to the opposite side of the two heat sinks 53, and the left and right walls of the two protection boxes 4 are opened with multiple connecting holes to facilitate air circulation between the two protection boxes 4 and the voltage suppression cabinet body 1.

[0033] See also Figure 2-3 The replacement assembly in this embodiment includes two cover plates 6, four snap blocks 61, three groups of T-shaped plates 68, a horizontal block 62 fixedly installed at the front ends of the left and right groups of snap blocks 61, a vertical rod 63 fixedly installed at the opposite ends of the upper and lower horizontal blocks 62, an operating block 64 fixedly installed at the front ends of the upper and lower vertical rods 63, and a reset assembly fixedly installed at the opposite side of the two vertical rods 63.

[0034] Among them, two T-shaped slots 69 are opened at the lower end of the support plate 3, and the T-shaped plate 68 is inserted into the inner side of the T-shaped slots 69, so that the silicone pad 54 can be inserted into the lower end of the support plate 3, which is convenient for the staff to replace the silicone pad 54 and the drying strip 55.

[0035] In addition, the protective box 4 is a rectangle with a hollow inner cavity and a missing front end. The upper and lower walls of the inner cavity of the protective box 4 are provided with snap grooves, and the snap blocks 61 are snapped into the inner sides of the snap grooves. The cover plate 6 is snapped into the snap grooves through two snap blocks 61, so that the cover plate 6 can be fixed to the front end of the protective box 4 so that the protective box 4 can be sealed, thereby the protective box 4 and the cover plate 6 can be disassembled, which is convenient for replacing the screen 51, the waterproof breathable membrane 52 and the heat sink 53.

[0036] In addition, two sliding holes are provided at the front and rear ends of the cover plate 6, and the operating block 64 and the cross block 62 are both slidably connected to the inner side of the sliding holes. The staff can drive the vertical rod 63 to move through the operating block 64, and the cross block 62 can be connected to the buckle block 61 through the two sliding holes on the rear side, so that the cross block 62 can drive the buckle block 61 to move on the rear side of the cover plate 6.
