Distribution network DC power supply systems are rather important in contemporary distribution network systems as they provide numerous power equipment consistent and dependable DC power supply support.
Covering DC110V, DC48V, DC24V, the system offers a range of voltage level choices to satisfy the varied demands of various power equipment for DC voltage, thereby assuring that all equipment may run stably under an appropriate voltage environment. The current imbalance is ≤1.33%; its voltage control precision is as high as ±0.5%; its current control accuracy is ±1.0%; its ripple factor is ≤0.5%). These outstanding performance criteria considerably increase the safety and dependability of power system operation by ensuring the stability and purity of the output DC power supply, therefore avoiding the damage to power equipment caused by voltage fluctuations, current instability and other difficulties. With great energy conversion efficiency, low energy loss, and a flawless mix of energy conservation and high efficiency, the system efficiency is ≥94%.
One very noteworthy feature is its original integrated design idea. Each module clearly divides tasks and together comprises of a distribution box (integrated monitoring module, high-frequency switch rectifier module, step-down module) and a Battery box. The distribution box's monitoring module employs LCD Chinese display and Chinese character menu, and key operation—very pleasant and practical—allows one to easily realize human-computer interaction. It offers sound and light alert features as well as strong battery intelligent management capabilities that enable precise monitoring and control of the battery charging and discharging process thus extending the battery life. Once the system has aberrant situations, like busbar insulation issues, it may set an alert in time to remind the staff to handle it; furthermore, the flash output function also offers convenience for the safety warning and status indicator of the system.
The module of high-frequency switching rectifiers has shown a sophisticated technological degree. By using high-frequency soft switching technology and power factor correction, one not only accomplishes self-cooling and heat dissipation but also saves space and money by not requiring more complicated heat dissipation equipment. It also has a high power factor, is small and quick. Effective protection against AC input over-voltage, under-voltage, over-temperature, over-current and output short circuit guarantees the safe and steady functioning of the module itself and the whole system under many complicated operating situations.
With its exact parameter performance, practical integrated design, intelligent monitoring function, advanced rectifier module technology, and power supply stability and dependability protection, the distribution network DC power supply system has become an indispensable key component in the distribution network project overall.
