Description
LSY107-10 series current transformer is a special transformer for outdoor pole mounted switch. When installed, it is fixed on the three- phase bushing of outdoor switch circuit breaker, which can realize short-circuit protection, single grounding (zero sequence) protection and provide power supply for controller. It can also be used in the three-phase bushing of the incoming and outgoing lines of the ring main unit, as the current measurement of electrical equipment, electric energy metering and microcomputer protection. At present, it has been widely used in ZW20, ZW27, ZW28, VSP5 and other outdoor pole mounted switches, which solves the problem that the internal space of pole mounted switch is too narrow to install zero sequence transformer, and has been well appraised by many users.
The iron core and secondary winding of the series transformer are made of high-quality epoxy resin and vacuum cast in a flame retardant plastic shell, which is moisture resistant, stable and maintenance free.
