Description
Combined type three-phase one-piece current transformer is suitable for installation in the three-phase casing of the ring main unit and the main column switchwhich used for three phase current and zero sequence current measurement and protectionalso can be used to various cable loop zero sequence current measurement and protection.
The zero sequence current transformer's core and secondary windings of this series is vacuum pouring in the flame retardant plastic shell by high quality epoxy resin. has the characteristic of moisture proof, table performance and dispensing with maintenance.
Construction
This type current transformer is designed for CT-301 type vacuum circuit breaker current transformation function. Its bus bar pouring insulationadopt high quality ring core or amorphous alloy, there are advantages of great nominal output and high accuracy. It use high quality outdoor resin, vacuum casting use soft glue secondary line, and set a variety of current ratio function matching hose and breaker, Adopt bus bar type structureeasy installation, then let the vacuum circuit breaker primary current-conducting rod through the current transformer center and rejoining secondary line
