ZW12-12 Outdoor Vacuum Circuit Breaker
Product Introduction
Overviwe:
ZW12-12 Outdoor Vacuum Circuit Breaker is mainly used for 10KV overhead lines as outgoing, sectional and user demarcation switches. The product consists of two parts: the switch body and the WDZK intelligent control device. The interruption of the ZW12-12 Outdoor Vacuum Circuit Breaker in the power cabinet is used as a separation switch, and the current transformer is placed on both sides. The optional WDZK-2 control device can detect the voltages on both sides respectively to realize automatic fault isolation and network reconstruction.
The ZW12-12 Outdoor Vacuum Circuit Breaker can also have a built-in special zero-sequence current transformer to realize zero-sequence grounding protection and alarm system. When the one-way radial power supply mode is used as a segment switch, branch switch or user boundary switch, the built-in single PT or built-in single-ended double PT can be selected, and the WD·ZK-3 control device can be selected. Because of that, automatic fault isolation and fault location can be realized.
Product Advantage:
-
Permanent magnet mechanism inside, small size, light weight, simple structure, few moving parts and high reliability.
-
The device and controller can be flexibly configured according to different application occasions to achieve various protection requirements.
-
The device can realize manual control, electric control, infrared control, remote control and other control methods, and can open GPRS wireless communication for remote monitoring.
-
The device can have built-in Potential Transformer, each phase of Potential Transformer provide insurance, easy installation, safe and reliable operation.
-
The device can have a built-in zero-sequence current transformer to achieve ground fault protection and alarm functions.
