1.LZZW-10kV 50/60 HZ Outdoor Dry Current Transformer Epoxy Resin Measuring Current Transformer
The transformer is one of import electrical appliances in electric system. It's similar to power transformer and also used to transformer voltage or current in the circuit. However, transforming voltage and current by power transformer aims at transferring electric energy while transforming voltage and current by transformer aims at measuring and monitoring voltage or current in the circuit. Generally, power transformer owns large capacity as well as large change difference of voltage or current. While transformer owns small capacity as well as smaller change difference of voltage or current. In measuring circuit. The transformer that transforms current and supplies electricity for current meter and relay is called current transformer. The transformer that transforms voltage and supplies electricity for voltage meter and relay is called voltage transformer.
I. Product description of LZZW-10 current transformer
This type OF transformer IS suitable FOR current and electric energy measurement and relay protection in outdoor power system with rated frequency 50Hz and rated voltage 10kV and below. It is a substitute for old oil-immersed products. The CURRENT transformer IS MADE OF outdoor epoxy resin WITH vacuum casting and its outer skirt is made of advanced silica gel pressure injection. It is fully enclosed pillar structure and has the characteristics of arc resistance, ultraviolet resistance and aging resistance. The shape adopts ANTI-umbrella skirt, the surface creepage distance is large, the secondary terminal is sealed with a metal protective cover, and there are wires under it and on the left and right side, which is convenient, safe and reliable and can realize the measures of anti-stealing electricity. There are four mounting holes on the channel steel of the base for installation.
