magnetic-bias arc suppression coil

The controller uses industrial computer platform, dual CPU architecture, multi-layer circuit board processing, stable and reliable operation of 3 use large screen touch LCD all Chinese display, parameter display, setting and query convenient and intuitive. The adjustment is accurate, fast and adjustable, and can be adjusted in the full range of rated current of 0~ 100%. The high voltage earthing fault line selection module is built with the residual current increasing cocoon method and the active power method. With RS232, RS485 and IEC61850 communication interface, it can communicate with the host computer and achieve long-distance signal transmission. It can realize the function of sound and light control of single-phase grounding fault. Equipped with standard printer, data printing and grounding letter printing can be realized. With one control two functions, one controller can control two sets of arc suppression coils.

Product features

1. Features of the device:

l  Higher safety: the damping resistance is connected in series at the outgoing line side of the arc suppression coil, which can effectively avoid the resonance overvoltage of the system.

l  Higher reliability: The device adopts STM32F103ZET6 chip as the core controller, and adopts strong and weak electrical isolation, isolated power supply, software and hardware watchdog, hardware continuous self-check technology, photoelectric isolation, and non-contact design to ensure the high reliability of the system .

l  Modularization of control system: the control unit can support two bus sections at most. Each functional module of the control unit is designed as an independent plug-in and configured according to the requirements of the user.

l  Flexible communication method: The controller has RS-232, RS-485 serial interfaces and communication components, which can be used as a sub-station to connect to various integrated automation systems for remote measurement, remote signaling, and remote control.
