DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] like Figure 1 and 2 As shown, the utility model relates to a novel high-voltage reharmonic filtering compensation cabinet, including a cabinet body 1, the cabinet body is made of a frame structure, the cabinet body includes a top plate and a bottom plate and a column 2 arranged between the top plate and the bottom plate, a corner support block 3 is arranged at the corner position formed by the top surface and the column and the bottom plate and the column, and a transverse connecting support 21 and a longitudinal connecting support 22 arranged perpendicularly and intersectingly are arranged on both sides of the cabinet body; an isolation plate 41 is arranged in the cabinet body, and the isolation plate divides the inner cavity of the cabinet body into a high-voltage busbar chamber 4 and a high-voltage component chamber, and a low-voltage instrument chamber 5 is arranged in the high-voltage busbar chamber, and the front of the cabinet body is rotatably connected with an instrument door 101 and a lower door 102, and the instrument door and the lower door are made of 2mm cold-rolled steel plates, and their surfaces are made in the form of an outward convex structural surface, multiple bending, frills and then bending, and are designed as a convex door form.

[0018] As a technical improvement, the isolation plate is provided with perforations, and wall sleeves 6 are provided at the perforations.

[0019] As a technical improvement, a first pressure relief plate 7 and a second pressure relief plate 8 are arranged on the top surface of the cabinet body, wherein the first pressure relief plate is preferably located above the component chamber, and the second pressure relief plate is located above the busbar chamber, serving as independent pressure relief plates.

[0020] As a technical improvement, a lifting ring 11 is set at the corner position of the top surface of the cabinet body, and an M20 lifting ring is used. The lifting ring is fixed by an angle steel. Since the weight of the cabinet usually exceeds 800 kg, and considering the unbalanced force of each lifting ring during lifting, and the M16 lifting ring can bear 600 kg, and the M20 lifting ring can bear 1000 kg. Therefore, the original M16 lifting ring is changed to an M20 lifting ring, and a 40 equilateral angle steel is added between the lifting ring and the top crossbeam to strengthen it, which greatly improves the load-bearing capacity and safety of the lifting process.

[0021] As a technical improvement, the back of the cabinet is sealed, and an upper shutter 10 and a lower shutter 9 are provided, wherein the width of the window gap is 3mm. For the heat dissipation design of the cabinet, the existing technology is to change the original 3mm heat dissipation through hole into a shutter with a 1mm gap, the upper shutter window faces upward, the lower shutter window faces downward, and the upper and lower windows are not facing people. The protection level of the entire cabinet can reach IP40, and it is safe and reliable.

[0022] As a technical improvement, the lower door is provided with MS887-3 door lock 103, wherein there are 4 locking points in the door, which meets the explosion-proof requirements and allows the door to be opened and closed in one step. This avoids the MS704-1 door lock used in the cabinet type in the prior art, which requires the installation of 4 locks and is very cumbersome to open and close the door.

[0023] As a technical improvement, the instrument door and the lower door are provided with decorative brows 12.

[0024] We take into account the convenience of pressure relief, wherein the first pressure relief plate and the second pressure relief plate are fixed in a manner that one side is a metal screw and the other side is a nylon screw.

[0025] In response to the various problems and unreasonable aspects of the product, in order to respond to market demand and the need for product upgrades in the new era, the company has referred to the experience of advanced foreign products in terms of cabinet structure, component layout, appearance, etc., as well as the new requirements put forward by customers for our company's products in normal engineering projects, and has made a brand-new design for the cabinet frame, component layout, and appearance.
