Description

Technical Field

[0001] The present application relates to the technical field of frequency converters, and in particular to a quickly detachable frequency converter base. Background Art

[0002] Frequency converter is an electronic device mainly used to adjust the speed and output power of AC motors. It controls the speed of the motor by changing the power frequency, thereby realizing the automatic control of mechanical equipment. Frequency converters are widely used in industrial production, home appliances, transportation and other fields, such as elevators, air conditioners, electric vehicles, etc.

[0003] The patent document with the published announcement number CN219351521U provides a frequency converter base that is easy to disassemble and repair, including a bottom plate, wherein the four corners of the lower end surface of the bottom plate are each connected to a support column; the left and right ends of the upper end surface of the bottom plate are each connected to a first guard plate, and the upper and rear ends of the upper end surface of the bottom plate are each connected to a second guard plate; a placement groove is provided on the upper end surface of the bottom plate, and the frequency converter is placed in the placement groove; and a plug-in component is provided on the bottom plate. The purpose of the utility model is to overcome the existing defects and provide a frequency converter base that is easy to disassemble and repair, which is easy to disassemble and avoids manual operation.

[0004] The inverter is a type of electrical equipment. In addition to being installed inside a ventilated, moisture-proof, and waterproof box, the inverter must also ensure that its application environment is dry. However, the above-mentioned device has grooves on the inner sides of the first and second protective plates. The first and second protective plates surround the inverter, so that once the inverter box comes into contact with external water, the water will flow along the inverter box and the first and second protective plates to the grooves. Once water accumulates in the grooves, it cannot flow out, thereby creating a humid environment, which can easily lead to inverter failure and affect the use effect. Utility Model Content
