Description

Technical Field

[0001] This utility model relates to the field of frequency converter expansion technology, specifically to a multi-module combination expansion structure based on frequency converters. Background Technology

[0002] In modern industrial production, frequency converters, as an important power control device, are widely used in motor speed regulation, energy-saving retrofitting, and other fields. With the continuous improvement of industrial automation, the power requirements for frequency converters are becoming increasingly diversified. In some large-scale industrial scenarios, a single frequency converter may not be able to meet the power requirements of the equipment. In such cases, it is necessary to combine multiple frequency converters to expand capacity and meet the needs of different power levels.

[0003] Currently, most inverter combination expansion structures on the market use plug-in connections with fixed lengths, requiring screw tightening for fixation after insertion. This connection method has several drawbacks. Firstly, the spacing between inverters may vary in different application scenarios, and plug-in connections struggle to adapt to combinations with varying spacing, leading to installation difficulties and poor versatility. Secondly, fixed connection structures are cumbersome to install and disassemble, requiring significant time and manpower, reducing the efficiency of equipment maintenance and upgrades. Therefore, developing multi-module combination expansion structures based on inverters has significant practical implications. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-module combination expansion structure based on frequency converters. This solves the problem that some frequency converter combination expansion structures, which use plug-in and screw-in connection methods, cannot adapt to the different spacing between frequency converters in different application scenarios. Fixed connection structures are also difficult to adapt to combinations of frequency converters with different spacings, resulting in installation difficulties and poor versatility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-module combination expansion structure based on frequency converters includes multiple frequency converter bodies and connection units disposed on the frequency converter bodies, wherein the connection units include:
