The ZW32-12 outdoor column vacuum circuit breaker is an outdoor distribution device with a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used to break/close load current, overload current and short-circuit current in power systems. It is suitable for protection and control in substations and industrial and mining enterprise distribution systems, and is more suitable for rural power grids and places with frequent operations.
Performance Features:
·The circuit breaker adopts a three-phase pillar structure. The pole is equipped with phase voltage, zero-sequence voltage, phase current, and zero-sequence current sensors, as well as built-in energy-taking capacitors, which can be flexibly arranged on the incoming or outgoing line side according to different customer needs. It has low power consumption and high accuracy. The sensor parameters meet the group standard T/CES018-2018 "Technical Conditions for 10kV and 20kV AC Sensors in Distribution Networks".
·An AC-DC module is installed inside the box, which can output a power supply with a voltage of 28V and a maximum power of 60W to meet the power consumption needs of intelligent terminals. It no longer relies on external PT power, reducing safety hazards. The circuit breaker has good sealing effect and can meet IP65/IP67 standards. It is a new generation of high-precision maintenance-free product that meets the latest requirements of the State Grid.
