Abstract

The invention discloses a frequency converter. The frequency converter includes a main body of the frequency converter and a window-moving assembly arranged on the main body of the frequency converter. The main body of the frequency converter comprises an operation keyboard, a face cover, a casing, a main board PCB, drive PCB board, terminals, capacitor PCB board and silicone retainer; the cover is buckled with the housing, and the operation keyboard is embedded in the cover and buckled with the housing; the main board PCB is connected through the connector It is fixed inside the housing; the terminals are welded on the capacitor PCB, and the main board PCB, the drive PCB, the terminals and the capacitor PCB are sequentially connected and arranged inside the housing; the frequency converter of the present invention operates by The integrated design of the keyboard is an independent module, and an installation space is reserved on the casing. The operation keyboard is installed on the casing and exposed to the opening of the cover, which is convenient for operation and easy to replace, and only needs to replace the operation keyboard; The pcb boards are respectively connected and installed in the casing, maximizing the use of the space in the casing.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a frequency converter. Background technique [0002] Inverter (Variable-frequency Drive, VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's operating power supply. With the continuous improvement of industrial automation, frequency converters have also been widely used. [0003] The frequency converter is composed of various components connected, but the connection settings of the existing components of the frequency converter are unreasonable, resulting in inconvenient disassembly and maintenance, especially the operation keyboard area composed of various knobs and buttons directly arranged on the panel, if If a certain knob or button is broken, the entire inverter needs to be repaired, which causes a lot of inconvenience.
