Three-phase transformer protection equipment

Microcomputer protection device
The three-phase transformer microcomputer protection device consists of high-integration, bus-free chip microcomputer, high-precision current and voltage transformer, high-insulation strength export intermediate relay, high-reliability switching power supply module and other components. The microcomputer protection device is mainly used for power plants, substations, distribution stations, etc. with voltage levels of 110KV and below, and can also be used for voltage and current protection and measurement and control of some systems with voltage levels between 70V-220V.
Differential protection device
The three-phase transformer differential protection device is mainly used to protect transformer equipment. The transformer differential protection device should have differential quick-break protection and compound ratio differential protection with or without secondary harmonic braking. It can be used for three-side differential current input (three-turn transformer) at most. It has a complete and powerful acquisition function for the voltage and current analog and switch quantity of the primary equipment, equipped with standard RS485 and industrial CAN communication ports, and realizes three-turn main transformer differential protection, two-turn main transformer differential protection, two-turn distribution transformer differential protection, non-electrical quantity protection and other protection and measurement and control functions through reasonable configuration.
