*With the rapid development of the power grid construction, power supply reliability requirements for safety more and more high,and in the power systemhe improvement of the distribution network operation requirements and feeder automation(FA) the need to build a single function equipment in the application of the distribution network is more and more shows its inconvenience From the development of the system and distribution network on, developed a series of using the modern electronic technology and communication technology, the computer technology, the sensor technology and network technology, will power distribution network real-timeinformation,information,and the user's information, power grid structure parametrs for integration,have fault detection function,protection control function the automatic measurement function, modern communication function and the event log function, can realize the automatic segmentation fault current, fast break fault isolation distribution node(FTU/TTU)intelligent integration switch is imperativeBased on this thought, the company developed the ZW32-12/M type outdoor permanent magnet type vacuum circuit breaker, widely used in the city grid as points off or contact switch, or used for rural substation to qualify as a distribution system outdoor switch,but effective points,and load current and short circuit current. Device configuration of the internal control and communication function measurement protection can fully satisfy the power distribution automation system requirements.* Because Wortai ZW32-12/M type outdoor permanent magnet type vacuum circuit breaker for many patent technology application, make it has many advantagesnoSF6,no oil, environmental influences small, it is favorable to the enviroment protection; Unit of small size light weight, easy to install column; Intelligent control unit is compact can simply installed in the bottom of the pillars, can be in within 100 meters of control switch and the points; Apply to urban and rural power grid on-site operation and remote control; Besides the battery and capacitance every six to seven years replacement of a outside, circuit breaker ontology lifelong free maintenance.
*Environmental temperaturno higher than +40ºC,no less than -40ºC;
*Air relative humidity: day average no greater than 95%,on average less than 90%;
*The altitude does not exceed 2000 m;
*Wind pressure not more than 700 Pa (equivalent to wind speed 34 m/s);
*Seismic intensity not more than eight level;
*No fire,explosion, serious filthy chemical corrosion and violent vibration of places.
*If the customers have other special requirements, can be in order to put forwardour company can offer most satisfied.
*Equipped with vacuum arcing chamber of the column in vacuum circuit breaker (performance is stable and reliable, and has no combustion and explosion danger, safety,free of maintenance, small volume, light weight and long service life etc; |
*Circuit breaker using permanent magnet operation system, the structure is simpleless parts,moving parts,only one, and the traditional spring institutions than nearly parts, greatly reduce the fault source, greatly enhancing the reliability. Also cancelled and prone to failure of mechanical off and lock device, make the whole system operation reliability greatly improved;
*Permanent magnetic actuator controller unique adaptive and self- check function, may to the of the pma optimization, make vacuum circuit breaker of mechanical properties to achieve the best, extending a permanent magnetic actuator and vacuum arcing chamber of life;
*Because the product the permanent magnetic actuator hold still, reliable and fast with the unique advantages, its inherent action time cant more than 10 ms and the action time consistent, very convenient at all levels in the circuit breaker protection parameter setting and action; |
