ZW32-40.5 outdoor high voltage AC vacuum circuit breaker

General introduction
The ZW32-40.5 outdoor high-voltage AC vacuum circuit breaker is a latest small outdoor high-voltage AC switchgear which has been independently developed by our company. With nominal voltage of 40.5KV, this series of product is applicable to overhead line, factories, mines and enterprises, power plants, transformer substation and other places using voltage of the same level. This product can meet the protection and operation requirements of the grid system, including open and close as well as connection and disconnection short-circuit current. It is characterized by excellent operating performance, high reliability, long service life, and free maintenance. Equipped with FTU intelligent control terminal, it can communicate with network automation main station via GPRS or optical fiber and accomplish network automation.

Description of function
Telemetering: capable of testing voltage, current and other AC analog quantities, battery voltage, temperature and other AC analog quantities.
Remote signaling:capable of testing switching status signal, switch energy storage signal, low voltage alarm of battery, and other status information; at the same time, it is capable of double-position telesignal processing and supports prioritized transmission of remote communication deflection;
Remote control: capable of radio frequency wireless remote control switch; it is equipped with local / remote option switch and can connect with the remote control divide-shut switch for master station.
Fault detection: equipped with single phase grounding, three-phase alternate protection, overload, anti-flashy flow, and other pr functions; besides, it can record the value of protection current;
Communication: have serial port and network communication interface, 101, 104 and other power standard communication protocols; the data can be uploaded to the master station via optical fiber / Ethernet, GPRS/CDMA and other means.
Self-diagnosis and self-recovery: capable of self-diagnosis; when the internal software and hardware are found abnormal, such abnormity can be recorded and reported timely. Additionally, the software is capable of self-recovery.
