Each side beam 2 is provided with two symmetrically arranged insulating mounting beams 3, thereby partitioning into a plurality of chambers for installing loads;

[0020] Above the front end face of the cabinet body 1, a first door panel 4 is provided. The first door panel 4 is provided with a first door glass 5 for observing the interior. Below it, a second door panel 6 is provided. The second door panel 6 is provided with a second door glass 7. At the corresponding positions on the rear end face of the cabinet body 1, a first door panel 4 and a second door panel 6 are also provided.

[0021] Through reasonable structural improvements, this application realizes multi-cavity installation. In addition, it conforms to product specifications and standardization, avoids misunderstandings and deviations in transformation requirements, unifies and standardizes products, and provides a better, faster, and more efficient service experience for production and all links.

[0022] In addition, the interior situation can be clearly viewed through the two door glasses.

[0023] In addition, the housing should be a closed structure made of metal. Its form and dimensions should be coordinated with the adjacent switchgear, maintaining the same height and depth. A hanging ring should be set on the top for hoisting.

[0024] In this embodiment, the first door panel 4 and the second door panel 6 are fixed by locking screws 8. The front and rear doors of the cabinet should be provided with sealing devices, and other positions that can enter the cabinet should have reliable sealing points. The sealing device adopts locking screws (column screws plus hand-locking nuts), and the screw column should be welded. It is forbidden to use built-in screws only on the inside (including the cabinet top), and it cannot be opened outside the cabinet.

[0025] In this embodiment, a symmetrically arranged first ground bar 9 and a second ground bar 10 are provided under the cabinet 1. The first ground bar 9 and the second ground bar 10 are connected by a connecting portion 11, and also include a grounding plate 12 connected to the cabinet 1, and the grounding plate 12 is connected to the connecting portion 11.

[0026] Specifically, the cabinet 1 is provided with a plurality of first ground bars 9 and a second ground bar 10 .

[0027] There are 4 grounding copper bars under the monitoring cabinet, with a specification of 25x4mm2. One copper bar is connected to the cabinet body, and the other copper bar is insulated from the cabinet body. At the same time, it must be equipped with a grounding terminal, which is a crimping type and can be connected to multi-strand copper wires with a cross-section of not less than 4mm2. The metal shell and door of the monitoring cabinet should have a grounding terminal and must be reliably grounded. All cabinet doors that can be opened are required to be grounded with copper braids.
