ZW32-12M Type Outdoor Intelligent Permanent Magnet Vacuum Circuit Breaker (with Manual Quick-closing Function Of Patents)
With the rapid development of the power grid construction, power supply reliability requirements for safety more and more high, and in the power system, the 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-time information, information, and the user's information, power grid structure parameters 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 imperative.
Based on this thought, the company developed the ZW32-12M 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.

VZW20A-12C type AC H.V. vacuum pole automatic controller is used in tri-phase electric system of AC 50 Hz, rated voltage 12kV. It can breaking and closing load current, overload current and short circuit fault current, as a device to control and protect electrical network.
The controller is an intelligentized device, matches sectionalizer to reach distribution automation without other control system. Consist of circuit breakerlwith mechanism operation), controller and control power, besides to opening or closing regular and fault current as circuit breaker, it can repeatedly auto reclosing by advanced setting times for sectionalizer to isolate fault circuits when the short circuit fault happen. The non-fault lines will resume power supply; if repeatedly auto reclosing failed, closing and interlock inside of the controller, another side of network, originally closing and interlock status will remove interlock and auto closing, non-fault lines resume power supply at once. The network automation could limit the power supply interrupted district into minimum range, it has high social benefit and economical benefit.
The product is practical and reliable, multiple functional, the controller uses microprocessor, the panel shown in digital, conveniently with person-machine talking, all the parameters could be adjusted, new function of GPRS communication system could achieve opening, closing operation and teledata communication function by mobile phone, it can transmit lines parameters and running state of the equipment.
The product adopts VZW20A-12 type outdoor AC H.V. vacuum circuit breaker as noumenon, the noumenon switching adopts vacuum interrupter to arc extinguishing and SF6 gas to isolate, the case adopts gas sealed, isolation structure technic. No leakiness of internal filling gas, the spring mechanism operation promotes with miniaturization and performance optimization design, operation reliability is more advanced than domestic traditional spring mechanism. Main circuit is sealed inside the case, it has the advantage of anti-explosion, anti-condensation, anti-nasty, no influence by outside environment, it is the first choice on controlling and protecting for intelligent electrical network.

ZW32-12M Type Outdoor Intelligent Permanent Magnet Vacuum Circuit Breaker (with Manual Quick-closing Function Of Patents)
With the rapid development of the power grid construction, power supply reliability requirements for safety more and more high, and in the power system, the 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-time information, information, and the user's information, power grid structure parameters 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 imperative.
Based on this thought, the company developed the ZW32-12M 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.

VZW20A-12C type AC H.V. vacuum pole automatic controller is used in tri-phase electric system of AC 50 Hz, rated voltage 12kV. It can breaking and closing load current, overload current and short circuit fault current, as a device to control and protect electrical network.
The controller is an intelligentized device, matches sectionalizer to reach distribution automation without other control system. Consist of circuit breakerlwith mechanism operation), controller and control power, besides to opening or closing regular and fault current as circuit breaker, it can repeatedly auto reclosing by advanced setting times for sectionalizer to isolate fault circuits when the short circuit fault happen. The non-fault lines will resume power supply; if repeatedly auto reclosing failed, closing and interlock inside of the controller, another side of network, originally closing and interlock status will remove interlock and auto closing, non-fault lines resume power supply at once. The network automation could limit the power supply interrupted district into minimum range, it has high social benefit and economical benefit.
The product is practical and reliable, multiple functional, the controller uses microprocessor, the panel shown in digital, conveniently with person-machine talking, all the parameters could be adjusted, new function of GPRS communication system could achieve opening, closing operation and teledata communication function by mobile phone, it can transmit lines parameters and running state of the equipment.
The product adopts VZW20A-12 type outdoor AC H.V. vacuum circuit breaker as noumenon, the noumenon switching adopts vacuum interrupter to arc extinguishing and SF6 gas to isolate, the case adopts gas sealed, isolation structure technic. No leakiness of internal filling gas, the spring mechanism operation promotes with miniaturization and performance optimization design, operation reliability is more advanced than domestic traditional spring mechanism. Main circuit is sealed inside the case, it has the advantage of anti-explosion, anti-condensation, anti-nasty, no influence by outside environment, it is the first choice on controlling and protecting for intelligent electrical network.
