氯碱企业10kV供电系统内部过电压的分析及其防护措施

Internal over-voltage analysis and protection measures of chlor alkali enterprises 10 kV power supply system

针对操作过电压和谐振过电压,采取在电压互感器PT上加装二次微机消谐装置,在10 kV母线上加装智能型接地补偿装置以及在电动机、变压器侧加装过电压保护器等办法,可以很好防护过电压对10 kV供电系统的威胁。

Aimed at operating over-voltage and resonance over-voltage, install two microcomputer harmonic elimination device on voltage transformer PT, install Intelligent earthing compensation device in 10 kV bus and install voltage protector on transformer side, could be very good to prevent over-vohage damage to the power supply system.
