Luzhou rural network of 10 kV vacuum circuit breakers ZW32-12 / 630A Luzhou intelligent outdoor high voltage vacuum circuit breaker

Luzhou rural network of 10 kV vacuum circuit breakers ZW32-12 / 630A Luzhou intelligent outdoor high voltage vacuum circuit breaker breaker hereinafter) for the three-phase AC 50HZ, rated voltage 12KV outdoor power distribution equipment. Mainly used for breaking, closing power system load current, overload current and short circuit current. For substation and industrial and mining enterprises distribution system protection and control of workplace use, and frequent operation of rural power grids. The circuit breaker has small size, light weight, anti-condensation, maintenance-free characteristics, can adapt to poor weather conditions. ZW32-12 type permanent outdoor vacuum circuit breaker performance advantages ZW32-12 type permanent outdoor vacuum circuit breaker with permanent magnet actuator to operate; the permanent magnetic holding force operating mechanism provided by a permanent magnet, so that the switch remains in the closing minutes position, the small number of mechanical parts, mechanical transmission chain is short. Thus greatly improving the reliability and mechanical life of the switch. The main characteristics of the product: solid epoxy insulation, no oil, no SF6, no harm to the environment breaking vacuum, axial magnetic field interrupter, reliable import outdoor special epoxy resin, UV-resistant, anti-flashover, not aging forever magnetic operating mechanism, maintenance-free, long-term reliable operation bistable permanent magnetic actuator, not demagnetization, permanent use mechanical life can reach more than 20,000 times the minimum compact structure, small size, light weight, easy to install and transport the box through a special treatment, no rust, can maintain long-lasting and beautiful appearance (optional stainless steel box) with high intelligent computer controller, offers a variety of features to meet users' various requirements can be realized with FTU remote control, monitoring and SCADA functions to achieve a high reliability, maintenance-free, good enough for a long life, after 23,000 times opening reverse excitation test proved demagnetization rate of less than 1% 2, long-life organization, more than 10 million times three, asymmetric magnetic structure, closing coil together with the electromagnetic force generated by the permanent magnet is the optimal solution to meet the vacuum interrupter reaction force characteristics. 4, the agency opening, closing time is short touch, the whole sub-gate, full closing time is short. 5, light weight, easy installation, versatility. 6, manual switching off easy, and reliable. 7, coil excitation voltage power supply flexible: can 220DC / 220AC, 110DC / 110AC. 8, with the opening and closing interlock 9, the excitation voltage undervoltage alarm lockout. 10, with the completion of permanent magnetic actuator switch is closed, opening operation with locking function 11, the monitoring control circuit voltage, low voltage alarm and lock together, opening Operation 12, with a communication function, adjustable switch is closed, the opening operation Time 13, the controller with intelligent anti-skip logic, ensure that the switch will not jump phenomenon 14, using IGBT control theory, compared to the way the contactor has a high operating life of 15 highly integrated: a, compact controller module design, suitable internal switch assembly; b, the controller core CPU board full surface-mount package, high integration; c, all core CPU and peripheral interfaces of all optical isolation, driving strong, high reliability; d, the control loop uses large-capacity IGBT, and with RC absorption, for most permanent magnetic actuator
