Product Overview

High-tech products specially designed according to the characteristics of railway automatic blocking and power supply of power transmission line mainly provide powersupply for centralized dispatching of railway system, centralized electrical interlocking of large stations, automatic blocking and first-level load of hump signal lights. It integrates the high-voltage ring main unit, signal transformer, low-voltage switchgear, dual-power monitoring device, power line automatic removing system and low-voltage switchgear control part, which is safe and reliable without external interference. It can not only monitor the signal power supply in real time and segment the faults of high voltage lines, but also automatically remove the power faults through the relationship between voltage and time. By directly judging the grounding fault section through the small power system, it also realizes remote meter reading.

This product is also suitable for other industrial applications requiring electric motion intelligence.
