ZW32-12/630-20 Outdoor High-voltage AC Vacuum Circuit Breaker (Digital Type) integrates primary and secondary fusion technology, including a solid-sealed pole (fusing current and voltage sensors with vacuum interrupter), on-site digital unit ADMU, power PT, and connecting cables. The solid-sealed pole integrates current and voltage sensors, achieving high-precision three-phase voltage and current signal acquisition, enhancing equipment integration and measurement accuracy. The APG process is used for integrated casting to achieve measurement, protection, and feeder automation functions.

Main Functions

• Based on the electronic pole-mounted breaker, equipped with on-site digital unit ADMU module, converting high-precision sampling data from electronic sensors into digital signals for error-free transmission over 8-10 meter cables.
• The ADMU module encodes collected data in Manchester format for transmission to the rear-stage device (FTU), with zero-sequence voltage synthesized within the ADMU module, eliminating the need for a zero-sequence voltage sensor.
• The secondary part adopts the latest standardized digital FTU for status monitoring, fault handling, line loss metering, etc.
• Can be directly matched with electronic combined transformers without any conversion modules or aggregation devices.
• Main shaft sliding transmission with no torque loss, few transmission parts, equipped with AC/DC universal permanent magnet energy storage motor.
