Intelligent circuit breakers integrate modern high-voltage zero arcing technology, electronic technology, electrical automation technology, network communication technology, computer and software technology, etc., adopting a modular structure that completely breaks through many shortcomings of traditional circuit breakers, combining protection, measurement, and monitoring in one. In addition to conventional control, protection, alarm, and setting functions such as overload, overcurrent, instantaneous trip, leakage, and grounding, they also feature human-machine interface display, storage, memory, logical analysis, judgment and selection, as well as network communication functions. They can display in real time various characteristic parameters such as temperature, current, voltage, power factor, active power, reactive power, etc., and store fault parameters and types, with self-diagnostic capability.Zinc oxide arrester live tester can measure the total current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of zinc oxide arresters. The large screen can display the real waveforms of voltage and current. This provides on-site actual operating data for operation and maintenance personnel to perform corresponding information query and fault judgment processing, laying the foundation for optimizing the system operation mode. Through its network communication technology, multiple intelligent circuit breakers can achieve two-way communication with the central control computer, forming an intelligent power supply and distribution system, realizing the "four remote" functions, and creating necessary equipment technical guarantees for unattended stations and achieving regional interlocking, remote monitoring, and operation mode adjustment.
