Based on years of application experience from domestic and international counterparts, and combined with the actual characteristics of domestic integrated automation systems, this power automation high-tech product, developed and manufactured by the microprocessor-based power distribution protection device, integrates multiple functions such as protection, monitoring, control, and communication. It is an ideal electrical unit for constructing intelligent switchgear.
This product has a built-in protection library consisting of more than twenty standard protection programs, possessing a complete and powerful acquisition function for analog and digital voltage and current quantities of primary equipment (current measurement is achieved through protection current transformers).
The microprocessor-based protection device for the distribution cabinet consists of highly integrated, bus-parallel-output microcontrollers, high-precision current and voltage transformers, high-insulation-strength output intermediate relays, and high-reliability switching power supply modules. The microprocessor-based protection device for switchgear is mainly used in switchgear with voltage levels of 110KV and below.
