医院使用净化电源的必要性探讨

The necessarity of the purified power supply in the hospital

本文叙述了从普通稳压电源发展到净化电源的发展过程 ,认为自动化、数字化、集成化、信息化的医疗仪器设备配置净化电源是很有必要的 ,分析了共模和差模干扰及三相电压的不平衡等电能质量问题对各仪器设备及信息系统的影响和损坏 ,并对普通稳压电源与净化电源的技术指标做了对比 ,探讨了医疗仪器设备配置净化电源的必要性。

The improvement of the electrical power supply is now from the ordinary one to the purified one.We think,the automaticalized,digitalized,integrated and civilized medical instruments all need to use the purified-power supply.We analyzed the troubles of electrical energy from the interference of the common-mode and different-mode also from the un-balanced of the tri-phasic voltage.We analyzed the effection and defection to the different medical instrument and information system from all these troubles.Meanwhile,we compared the technical data of the ordinary voltage-regulaˉtor with the purified-power supply.We discussed the necessity of the purified-power supply for the medical instruˉment.
