Customized processing of variable frequency control cabinet

Variable frequency cabinetOrdinary power cabinets or control cabinets have been changed from traditional drag methods to variable frequency drag methods. In short: Apply a frequency converter to drive the control cabinet of the power device. Due to its excellent starting performance, speed regulation performance, and energy-saving effect, it has become the currently promoted force driven method for variable frequency cabinets.

Application scope:

1. Widely used in various types of tap water supply systems in urban and rural areas
2. Constant pressure control of water supply for high-rise buildings, domestic and fire-fighting water, and closed-loop water supply for industrial production conditions
3. Automatic control of boiler feedwater pump and thermal heating circulation pump
4. Irrigation of farmland and control of fountains
5. Air conditioning system and cooling circulating water control
6. Secondary pressurization control of flow systems in water plants, pump stations, and petrochemical industries
7. TSLB frequency conversion cabinet can be used for various motor control cabinets that require energy-saving renovation or zero speed starting production lines.

Function of frequency conversion cabinet:

The high-power frequency conversion cabinet can minimize the impact of high-power water pumps and fans on the power grid and the voltage drop of the first mate, resulting in significant energy-saving effects
As an early commodity, the general frequency converter has been on the market in China for nearly a decade, with sales increasing year by year and a market worth over several billion yuan (RMB) this year. Among them, various imported brands are predominant, with power ranging from hundreds of watts to thousands of kilowatts; Simple or complex functionality; Low or high precision; Slow or fast response: with or without PG (speedometer); with or without noise, etc.
For many users, there have been multiple updates in the past decade, and most of the frequency converters currently in use belong to the most advanced models. From an application perspective, our level is no different from that of developed countries. As a domestic manufacturer, we have been actively promoting advanced foreign technologies and developing domestically produced frequency converters to catch up with the level of developed countries in the world over the past decade.
Reviewing the development of universal frequency converter technology abroad in the past decade is of great significance for gaining a deeper understanding of the direction of AC transmission and control technology, as well as how to develop our own products from a high starting point combined with China's national conditions
