Description

Electrical equipment cabinet suitable for cabinet combining, cabinet combining integration and top cover manufacturing method thereof

Technical Field

The invention belongs to the technical field of electrical equipment shells, and particularly relates to a high-IP protection-level electrical equipment cabinet suitable for cabinet combining, a cabinet combining integration applying the electrical equipment cabinet and a top cover efficient manufacturing method of the electrical equipment cabinet, which can effectively relieve the problem of cabinet combining and temperature rise effect superposition while solving the problem of complicated cabinet combining installation.

Background

An electrical equipment cabinet refers to a cabinet body for installing, protecting and supporting electrical or electronic equipment, and a power distribution cabinet, a switch cabinet, a communication cabinet and the like are common. The electrical equipment cabinet housing is an important component of the cabinet body. The housing prevents the operator from touching the charged parts and the ingress of foreign solids, which is the most immediate safeguard. Temperature rise is another important index of the electric equipment cabinet, and directly affects the quality and service life of the product. The national standard GB 4208-2017, "protection rating for housing (IP code)" is a standard for providing protection rating for electrical equipment housings. In some environments where use is limited, such as where contaminated or dust laden air and water are not allowed into the interior, high IP protection level electrical equipment cabinets must be used. The high-IP protection-level electric equipment cabinet cannot be randomly provided with the radiating holes and cannot radiate by using natural wind, so that the high-IP protection-level electric equipment cabinet often adopts a mode of 'internal forced ventilation' + 'natural radiating of a shell', namely, an internal forced ventilation measure (such as fan installation) is taken as a main part, and the temperature rise problem in the operation process of the electric equipment cabinet is solved by taking a contact radiating mode of the shell and the outside as an auxiliary part. Taking a switch cabinet as an example, the current temperature rise experiment of the switch cabinet is based on the common technical requirements of GB11022 standards for high-voltage switch equipment and control equipment and GB3906 standards for 3.6 kV-40.5 kV alternating-current metal closed switch equipment and control equipment. However, no matter the cabinet is a switch cabinet or other electrical equipment cabinets such as a power distribution cabinet, according to the national standard requirement, only 1.1 times rated current is applied to a single-cabinet testing machine, the periphery of the testing cabinet is in a state of good contact with the outside without shielding, the state is favorable for heat dissipation of the cabinet body, and the electrical equipment cabinets are often used in parallel when in actual electrified operation.

For a cabinet combining integration formed by connecting two or more electric equipment cabinets, two sides of the electric equipment cabinet with the installation position in the middle are shielded, heat dissipation is not facilitated, heat effects between two electric equipment cabinets are overlapped, and a certain potential safety hazard exists in long-term operation of the cabinet combining integration. In addition, the cabinet combining installation of the electric equipment cabinets mainly comprises bottom installation between every two electric equipment cabinets and top installation between every two electric equipment cabinets, and the bottom installation between every two electric equipment cabinets is mainly assembled through fasteners such as screw bolts; and the top installation between every two electric equipment cabinets needs to additionally design structures such as a mounting plate, a conical guide rod, a screw bolt and the like, and then the electric equipment cabinets are installed by combining auxiliary tools such as a spanner and the like. For the intermediate cabinet, six mounting points are generally arranged, each mounting point needs to be repeatedly operated by workers through tools such as a spanner, and the like, and the mounting is complex, low in speed, long in time consumption and high in labor intensity.
