随着供电可靠性的不断提高,对10千伏双电源自动切换装置的需求正逐渐增加,然而,目前市场上的产品或多或少地存在着响应时间慢、控制线路复杂、可靠性差或互换性差等问题。鉴于此,本方案尝试利用在配网自动化系统中采用真空负荷开关柜及其控制装置,在保障设备高可靠安全运行的前提下,实现双电源互为备用的电缆供电自动切换功能。
With the continuous improvement of power supply reliability, the demand for an automatic switching device of 10 kV dual power supply is gradually increasing. However, products on the market today have more or less slow response times, complicated control circuits, poor reliability or mutual Poor sex change and other issues. In view of this, the program attempts to use the vacuum load switchgear and control devices in the distribution network automation system to ensure that the equipment is safe and reliable operation of the premise, to achieve dual standby power supply for each cable automatically switch power supply.
