Explain difference between AIS and GIS. MV switchgear is an important part of power distribution system for maintaining the continuity of service, and you have to consider some different aspects based on your needs before selecting a suitable MV switchgear.
What is ACR Auto Recloser? Auto recloser (ACR) also named automatic circuit recloser is recognized by electric utilities throughout the world as an essential device for achieving their prime goal: providing maximum continuity of electric service to customers.
Details introduction about outdoor auto vacuum recloser which manufactured by Rockwill Electric. This page will help learn more knowledges about RCW auto recloser as improvements in parts and assemblies are made.
What is Grounding? Grounding refers to connecting the neutral point, shell or bracket of the equipment and electrical device with the grounding device by conductor. This is the way to prevent electric shock and equipment damage.
What is Distance Protection Relay? Distance protection relay is the name given to the protection, whose action depends on the distance of the feeding point to the fault. The time of operation of such protection is a function of the ratio of voltage and current, i.e., impedance.
What is compact substation CSS? The CSS Compact substation is actual a prefabricated eletric equipment unit which is comprising of MV & MV switchgear, Power & Distribution transformer, LV switchboard, Connection busbar and other accessories.
At present, most enterprises are connected to the power grid by using 33kV box type prefabricated compact substation built by themselves. Therefore, the quality control of box type substation is very important, This not only affects the reliability of power supply, but also has a great impact on the normal operation and economic benefits of the enterprise. So it is very important to strictly control the quality of the installation process. This paper analyzes the construction quality control of the 33kV box type substation installation, puts forward the key quality control points of the installation and construction of 33kV box type prefabricated compact substation, and expounds the concrete measures of quality control
Ring Main Unit: indoor ac high voltage gas insulated metal-enclosed switchgear (RMU) is a new generation of switchgear equipment, the main switch can either use permanent magnetic vacuum circuit breaker or spring mechanism vacuum circuit breaker.
