Problems solved by technology
[0003] In the existing technology, the installation of the back cover of the inverter shell has always been a problem. Usually, the back cover is installed on the shell with screws, but this is easy to cause when the inverter has a problem, the back cover is not easy to disassemble and the maintenance process is slow. At the same time, if it is installed with screws, once it is used for a long time, it is easy to cause the screws to fall off, and it is also accompanied by the problem that the screws are corroded and difficult to disassemble.

Description
technical field [0001] The invention relates to the technical field of inverter casing installation, in particular to an installation structure for the rear cover of the inverter casing. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. It is mainly composed of rectification, filtering, inverter, braking unit, drive unit, detection unit and micro-processing unit. The frequency converter has many protection functions, such as over-current, over-voltage, overload protection and so on. [0003] In the existing technology, the installation of the back cover of the inverter shell has always been a problem. Usually, the back cover is installed on the shell with screws, but this is easy to cause when the inverter has a problem, the back cover is not easy to disassemble and the maintenance proc...
