Control cabinet of inverter driving power unit

The frequency conversion cabinet is a control cabinet that uses a frequency converter to drive the power device. It is widely used in various types of tap water supply systems in urban and rural areas.

The high-power frequency conversion cabinet can minimize the impact of high-power water pumps and fans on the power grid and the significant voltage drop, and has a significant power-saving effect.

It has been nearly ten years since general-purpose frequency converters were the first products to be launched in China. Sales have increased year by year, with a market worth more than billions of yuan (RMB) this year. in. Most of them are imported brands, with power ranging from a hundred watts to thousands of kilowatts; simple or complex functions; low or high accuracy; slow or fast response: with PG (speed measuring machine) or without PG; with or without noise, etc.

For many users, they have experienced many updates in the past ten years, and most of the frequency converters used now are advanced models. From an application perspective, our level is no different from that of developed countries. As a domestic manufacturer, through the past ten years, it has marketed advanced foreign technologies and is actively developing independent development of domestic inverters. Strive to catch up with the level of developed countries in the world.

Reviewing the development of foreign general-purpose inverter technology in the past ten years should be said to have very positive significance for a deep understanding of the trend of AC drive and control technology, and how to develop my country's own products based on a high starting point and combined with my country's national conditions.
