Description
Technical Field
The utility model belongs to the technical field of electrical control equipment, especially, relate to an installation and disassemble convenient converter.
Background
With the continuous extension of the application field of the power electronic technology, the frequency converter gradually deepens into each industrial field, so that the market has higher and higher requirements on the performance of the frequency converter, and the competition between the performance and the price of the frequency converter is more and more intense. The simple degree of the structure and the convenience of disassembly and assembly are all key factors for determining the performance of the frequency converter.
The shell of the existing frequency converter generally comprises an upper shell and a lower shell, the shell is assembled mainly in a screw connection mode, and screw holes are reserved in the upper shell and the lower shell. When the frequency converter is assembled, a circuit board is firstly installed on one substrate through screws, the substrate is installed in the lower shell through screws, then the circuit board is installed on the other substrate through screws, the substrate is also installed in the lower shell through screws, and finally the upper shell and the lower shell are connected through screws. The frequency converter shell with the structure is troublesome to assemble and low in efficiency.
Disclosure of Invention
The utility model aims at providing an installation and disassemble convenient converter to the not enough of above-mentioned prior art existence.
The utility model adopts the technical proposal that: a frequency converter convenient to mount and dismount comprises a shell, a frequency converter module arranged in the shell and a frequency converter controller arranged on the upper surface of the shell, wherein the frequency converter module comprises a circuit board and an electric element on the circuit board; the shell comprises a bottom shell, a lower middle shell, an upper middle shell and a top shell which are sequentially arranged from bottom to top, wherein four corners of the bottom shell, the lower middle shell, the upper middle shell and the top shell are respectively provided with a connecting wing plate which is opposite up and down, through holes are formed in the connecting wing plates, and the bottom shell, the lower middle shell, the upper middle shell and the top shell are mutually spliced by bolts and nuts through the through holes in the connecting wing plates to form the shell; the lower end of the lower middle shell is provided with a lower substrate for mounting a circuit board, and the upper end of the upper middle shell is provided with an upper substrate for mounting the circuit board.
And the side walls of the bottom shell, the lower middle shell and the top shell are respectively provided with a ventilation window.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses when the equipment, at first installation circuit board on upper substrate and infrabasal plate, then overlap drain pan, lower mesochite, last mesochite and topshell according to upper and lower order and insert the through-hole on the connection pterygoid lamina with the bolt, fasten with the nut, can accomplish the equipment, the equipment is very convenient and fast, efficient.
