conductor
导体是提供负荷电流的通路。其主要技术指标和要求:
Conductor is the access to the load current. Its main technical specifications and requirements:
1)导体截面和直流电阻:由于电流通过导体时因导体存在电阻而会产生热,因此,要根据输送电流量选择合适的导体截面,其直流电阻应符合规定值,以满足电缆运行时的热稳定要求。
1) conductor cross-section and DC resistance: because the current through a conductor due to the conductor resistance exists and produces heat, therefore, according to the transmission flow selection of appropriate section conductor, the DC resistance shall conform to the specified value, in order to meet the requirements of the thermal stability of cable operation.
2) conductor structure: the conductor is also a cable to work at the high voltage electrode, and the surface electric field strength is maximum, if the local have burr then the electric field strength will be greater. Therefore, the design and production departments and connected to the conductor manufacture joint, one of the main technical problem to be solved is to make the conductor surface as far as possible to smooth without burr, in order to improve the conductor surface field distribution.
