Transformers Classification: By function: voltage transformer: If JDZ series current transformers: as filling material in accordance with points LZZB series: Oil transformer: Internal filled transformer insulating oil dry: according to internal filled epoxy closed or semi-closed transformer rating: As part of the claw-shaped JDZ transformer, terminals and other exposed transformer factory direct, the other part is closed. Fully enclosed transformer: the body is closed up. Combined current and voltage transformers: Combined transformer combination of current and voltage transformers made more attached to the high-pressure metering box, transformer cabinet, or used as a measurement of electrical energy as a power source electrical equipment protection device. Combined current and voltage transformers are the two or three current transformer primary and secondary windings and core and voltage transformer primary and secondary windings and transformer core opening, fixed to the steel body frame, immersion equipment There are transformer oil cabinets, one secondary winding outlet are drawn zero sequence current transformer, then outside the box is high on voltage insulator, an insulating, closed whole. Supply line connected to the primary side and the secondary side of the metering device or relay device is connected. Depending on needs, the combined current and voltage transformers into V / V wiring and Y / Y connection of two to three-phase power metering when balanced or unbalanced load.
