外露非带电金属部分 meaning in English
exposed conductive part
Examples
- Typical examples are water mains and gas pipes . equipotential bonding consists of main and supplementary equipotential bondings . it means the electrical connection linking various exposed conductive parts and extraneous conductive parts so as to achieve a substantially equal potential
至于等电位导体的作用，其实就是将各个外露非带电金属部分和非电气装置金属部分作电气性连接，使各部分的电位在颇大程度上相等。 - Designers and registered electrical workers may be uncertain whether conductive parts such as metallic bathroom accessories , metallic windows or metallic door handles are extraneous conductive parts . when difficulties are encountered , you may carry out a measurement as illustrated in figures 4 and 5 . in figure 4 , a is an exposed conductive part with a resistance rcpc to main earthing terminal
附图四载列外露非带电金属部分a及怀疑为非电气装置金属部分b (例如是金属水喉管或木门的金属手柄) ， a对总接地终端的阻抗为rcpc ， b对地的阻抗为rx 。 - Figure 1 illustrates the connection arrangement of circuit protective conductors ( cpc ) and bonding conductors to exposed and extraneous conductive parts . by proper installation of automatic disconnection devices , cpc and equipotential bonding , in case of an earth fault occurred in an installation , the voltage on any exposedextraneous conductive parts occurring anywhere in the installation should be of such magnitude and duration as not to cause danger ( please refer to figure 2 and 3 )
因此，当电力装置发生故障时，由于线路得到相关截流器的保护，电力装置的任何一处的外露非带电金属部分和非电气装置金属部分的电压，其强度及持续时间皆不致引起危险(请参阅附图二及三) 。
