摘　　要：2006年起,全国水情报讯采用新的水情信息编码标准,普遍使用淮委淮信报讯系统对水文信息进行编码和发送,使用泰丰888专用电话,为使电话不受停电影响,研制了专用电源。介绍了专用电源的原理、供电方式,以及技术指标。,分析了电源的四个组成电路:交流供电、太阳能供电、降噪及稳压电路。该专用电源已在山东黄河所有测站推广应用,取得了较好的效果。From 2006, new standard for hydrological information code has been used all over the country, water regime information transmission system developed by Huaihe Water Resources Commission has been popularized to encode and transmit hydrological information. A dedicated power supply is developed to ensure that Taifeng 888 dedicated telephone could not be affected by power failure. The author presents theory, power supply methods and technical specifications, as well as makes analysis on four constituted circuits, that is AC power supply, solar power supply, noise reduction and stabilized power circuits. The dedicated power supply has been popularized in measuring stations along theYellow River in Shandong province, and has achieved excellent results.
