在民用建筑电气系统中,谐波除了很小一部分由电源本身以及输配电环节产生以外,绝大部分是由电气系统中存在的非线性负荷产生。民用建筑中主要存在着如下的谐波源:发电机、变压器、电动机、气体放电类光源和电力电子设备。谐波会对变压器、电动机、导线、电容器、继电器、电力测量仪表以及通信系统产生不同程度的危害。鉴于谐波的危害严重,必须要采取适当的措施来消除或抑制谐波。在民用建筑电气系统设计中,以JGJ/T16—2008《民用建筑电气设计规范》为依据,可以从以下几
In civil electrical systems, except for a small part of the harmonics generated by the power supply itself, as well as the transmission and distribution links, the majority of the harmonics are generated by nonlinear loads in the electrical system. Civil buildings mainly exist in the following harmonic sources: generators, transformers, motors, gas discharge light source and power electronics. Harmonics can cause varying degrees of damage to transformers, motors, wires, capacitors, relays, power meters, and communications systems. In view of the serious harm of harmonics, we must take appropriate measures to eliminate or suppress harmonics. In the civil electrical system design, JGJ / T16-2008 “civil electrical design code” as the basis, you can from the following
