Switch cabinet convenient for installing long bus

Abstract

The invention discloses a switch cabinet convenient for installing a long bus. The switch cabinet includes a switch cabinet body, a detachable cabinet top arranged on the switch cabinet body, a bus bridge arranged at the lower end of the cabinet top, and a bus frame erected on the bus bridge. The cabinet top includes multiple cabinet top modules inserted into one another in a sliding manner. The bus frame includes a bottom rack and a top rack which are jointed vertically. The bottom rack and the top rack are of the same structure, and are arranged in a mirroring manner. An appropriate number of cabinet top modules are selected and used according to the need to assemble or disassemble the switch cabinet, and the parts on the top of the switch cabinet are easy to maintain and replace. The bus frame is vertically installed, so that a bus can be put in the bottom rack in advance in the installation process of the bus frame, and the position of the bus can be controlled and adjusted freelyand conveniently. The number of the bus frame can be easily increased or decreased, and expansion and maintenance of the switch cabinet are facilitated.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a switchgear for easy installation of long busbars. Background technique [0002] Generally, the structure of the cabinet frame of the existing switchgear is generally made according to the specific required size. The connection methods of each structural piece are mainly non-detachable connection methods such as welding, or the disassembly end of the fastener connection is inside the cabinet body. After the production is completed, it is difficult to disassemble from the outside, especially the top. When performing maintenance or parts replacement, especially when the components on the top of the cabinet are damaged and need to be repaired or replaced, or components need to be added or removed for capacity expansion or reduction , from the inside of the cabinet, when various other components are covered with the switch cabinet, the maintenance work is time-consuming and laborio...

Problems solved by technology

[0002] Generally, the structure of the cabinet frame of the existing switchgear is generally made according to the specific required size. The connection methods of each structural piece are mainly non-detachable connection methods such as welding, or the disassembly end of the fastener connection is inside the cabinet body. After the production is completed, it is difficult to disassemble from the outside, especially the top. When performing maintenance or parts replacement, especially when the components on the top of the cabinet are damaged and need to be repaired or replaced, or components need to be added or removed for capacity expansion or reduction , from the inside of the cabinet, when various other components are covered with the switch cabinet, the maintenance work is time-consuming and laborious, and it is difficult to carry out, and the installation of the existing busbar is generally horizontally horizontal from the side after the busbar frame is completely installed. To be inserted into the socket, the designer needs to determine the length and quantity of the busbars and the layout method in advance, and the assembly process requirements are very high. The greater the distance between adjacent busbar frames, the more difficult the assembly will be; once the overall assembly of the power distribution cabinet is completed, it will be very troublesome when it needs to be expanded or repaired, and it is almost impossible
