What’s the technical features of ZW32-12 DEEP FUSION OUTDOOR HIGH VOLTAGE VACUUM CIRCUIT BREAKER SERIES（CAPACITIVE POWER TAKING）?
- ·ZW32-12 DEEP FUSION OUTDOOR HIGH VOLTAGE VACUUM CIRCUIT BREAKER SERIES（CAPACITIVE POWER TAKING） mainly consists of three-phase pole, spring operating mechanism, drive system, conducting loop, control unit and housing (made of ordinary carbon steel spray or stainless steel). The overall structure is of the three-phase pole type with miniaturization design, full-closed structure and good sealing property, especially suitable for cold and wet areas;
- ·The efficient and reliable spring operating mechanism (manual or electric; with manual functions or neardistance remote control for the electric type), featuring with low-power energy-storage motor and low opening and closing energy consumption. The operating mechanism is sealed in the box to effectively prevent rust to parts, guaranteeing the reliable action of mechanism;
- ·The pole is made of imported epoxy resin and coated with silicone rubber featuring with high temperature, low temperature, ultraviolet ray and aging resistance;
·An external two-phase or three-phase protective current transformer is provided to realize overcurrent protection and fault current quick-break protection together with inrush current, and the protection delay time can be adjustable; - ·The interphase protection CT and zero-sequence CT integrated structure can be configured to realize parameter setting, single-phase grounding protection, three-section protection, reclosing, and fault accident memory together with the intelligent controller (the external power supply PT is used to supply the operating power); the controller has the corresponding communication module with data uploading to master station, fault feedback and “four-remote” functions to form an intelligent circuit breaker achieving distribution network automation;
- ·The circuit breaker can be equipped with an isolating knife switch (at single or dual sides) with threephase linkage to form an obvious isolating distance at the incoming (outgoing) side; a reliable mechanical anti-misoperation interlock is provided between the main switch and the isolating switch to guarantee safe and reliable operation.
