The CYZW32 Series pole-mounted Automatic recloser is particularly well-suited for harsh outdoor environments, such as extreme temperatures, wind, rain, and pollution. The device effectively addresses issues associated with traditional manual operations, such as inefficiency and prolonged power outages, and is a core component in enhancing the continuity and reliability of distribution network power supply.
The product is capable of breaking load, overload, and short-circuit currents, and supports dual operation modes (manual/electric). It is equipped with an advanced intelligent controller that enables the monitoring of operating statuses such as voltage, current, and switch position. It can Automatically identify fault types, including short circuits and overloads, quickly disconnect fault circuits, and Automatically reclose according to the preset number of attempts, thereby achieving distribution Automation.
It features a modular design, with debugging completed in the factory. On-site operation is straightforward, and the requirement for operators' professional technical expertise is relatively low.
It is equipped with functions such as remote control, multiple protections, automatic reclosing, and status monitoring.Through feeder automation technology, it achieves rapid fault isolation and power supply restoration in non-faulty areas.
It employs vacuum arc-extinguishing technology to ensure reliable breaking; alloy-reinforced contacts are utilized to minimize arc ablation to the greatest extent.
The recloser has built-in voltage and current sensors, eliminating the need for additional measuring devices and reducing its volume by 1/3. It adopts the Automatic-Pressure-Gelation(APG) casting process, and the partial discharge quantity of the whole machine does not exceed 10pC.
