ZW32-27kV outdoor high-voltage AC vacuum circuit breaker automatic recloser (hereinafter referred to as "recloser") adopts the principle of vacuum arc extinguishing. It is a three-phase AC 50Hz/60Hz outdoor high-voltage switchgear. It is mainly used for rural power grids and urban power grids. -35kV outdoor power distribution system is used to divide and combine load current, overload current and short-circuit current; it can also be used in other similar places. The ZW32 series outdoor AC high-voltage vacuum circuit breaker complies with standards such as GB 1984 "AC High-Voltage Circuit Breaker" and the International Electrotechnical Commission IEC 60056 "High-Voltage AC Circuit Breaker".
The recloser adopts solid insulation process technology to deeply integrate the vacuum arc extinguishing chamber, voltage sensor, current sensor, zero sequence current sensor, etc. with the main circuit inside the insulating pole, becoming a primary and secondary fusion and integrated solid insulated vacuum circuit breaker. . This product can be used with intelligent controllers to meet the functional requirements of reclosers, automatic sectionalizers, contact switches and user boundary switches on distribution network lines. At the same time, it can also connect to the central master station through various communication protocols, GPRS and other communication methods to form distribution network automation.
The recloser is an automatic high-voltage electrical switch that can identify transient and permanent faults in the line, automatically clear the transient fault in the line, isolate the permanently faulty line, automatically restore the power supply to the power grid in non-faulty areas, and avoid causing long-term and large-area power outages. , to realize distribution network automation.
The vacuum recloser adopts pole-embedded technology, a sealed vacuum bottle for fault interruption, and epoxy resin and silicone rubber for insulation. A permanent magnet mechanism is configured and combined with a spring mechanism. When the battery of the permanent magnet mechanism is exhausted, the closing and opening operations can be enabled through the spring mechanism.
Reclosers provide an important foundation for achieving high safety and reliability of outdoor medium-voltage overhead lines, and are regarded by power companies around the world as important power equipment for realizing feeder automation. It detects and interrupts fault current and automatically restores service after a momentary power outage. Transient faults include transient circuit abnormalities caused by lightning, falling branches, wires blown by the wind, contact by birds, etc., but faults that can be eliminated automatically.
The intelligent distribution recloser is a flexible outdoor vacuum switchgear that can be installed either overhead on a pole or structurally on the ground. When a temporary line failure occurs, it can trip and reclose multiple times (usually set to 3 to 4 times). If the fault is permanent, the recloser will lock after a preset number of recloses, isolating the faulty part from the main part of the system to avoid expanding the scope of the fault.
Reclosers save a lot of time and money in power operation and maintenance. It can minimize the need for staff to go to the site for inspection and maintenance, minimize the power outage area, and help staff quickly locate problems and restore power supply. Ensure stable power consumption in residential, commercial, industrial and public facilities, and avoid heavy losses caused by frequent power outages.
It can be adapted to every field of application and meets all requirements for outdoor use. It combines cutting-edge technology with high-quality engineering expertise to provide the best solutions and lead the medium-voltage power network into digitalization and intelligence.
The pole-mounted recloser is a high-performance distribution switch. Its advantages are more obvious in ensuring the safety of equipment operation in coastal environments characterized by high air salt, high humidity, serious pollution, and many birds.
Primary Recloser Part:
The recloser controller integrates microprocessing technology and modern network communication technology. It supports a variety of communication protocols and allows the selection of multiple communication methods to form a communication network. The switch can be operated locally manually or remotely, or remotely controlled through the communication network. If equipped with corresponding recloser or segmentation control device, it can be used as a recloser or segmentation device.
