HX-600 series intelligent permanent magnet switch controller
The intelligent permanent magnet controller is specifically designed for the intelligent control of permanent magnet mechanism switch units. It achieves protection control and communication functions. The controller and the switch unit are electrically connected through control cables and aviation connectors to integrate protection, measurement, control, detection, and telecontrol functions. It can automatically eliminate the impact of transient faults on the line and isolate permanently faulty sections, automatically restoring power to non-faulty sections to avoid prolonged large-scale power outages. This achieves intelligent grid and automatic monitoring functions. Permanent magnet operating mechanisms are widely used in the national power grid due to their advantages of compact size, light weight, simple structure, reliable operation, maintenance-free operation, and long service life.

Product Overview
The intelligent permanent magnet controller is specifically designed for the intelligent control of permanent magnet mechanism switch units, realizing protection control and communication functions. The controller and the switch unit are electrically connected through control cables and aviation connectors to integrate protection, measurement, control, detection, and telecontrol functions. It can automatically eliminate the impact of transient faults on the line, isolate permanently faulty sections, and automatically restore power to non-faulty sections, avoiding long-term large-scale power outages. This achieves intelligent grid and automatic monitoring functions. Permanent magnet operating mechanisms are widely used in the national power grid due to their advantages of compact size, light weight, simple structure, reliable operation, maintenance-free, and long service life.
Our company's independently developed intelligent permanent magnet controller adopts a perfect design concept of microcomputer-type relay protection. The controller has a total of 5 analog input channels: A-phase current, B-phase current, C-phase current, zero-sequence current, and AC interphase voltage. The controller monitors the values of these analog quantities in real time and compares them with set values to determine line faults and perform corresponding processing. It has a 485/232 communication interface. This intelligent permanent magnet controller uses a UPS uninterrupted power supply design and has an automatic battery protection function. During a long power outage, it can automatically cut off the battery power to prevent long-term battery discharge and damage.
