The product can be used as the main transformer 35kV substation 10kV and 10kV outlet side switch, but also as a distribution network of column switch, and this combined with the company's controller can easily achieve control, protection, measurement, communication is to achieve distribution automation and miniaturization substation device of choice. ▁▁▁▁▁ ━━━━━ two main functions, AB-3S-12 permanent magnet outdoor vacuum circuit breaker main functions: 1, the protection function: automatic identification of the fault current, instantaneous current quick break, limit current quick break, time overcurrent direction over current, over voltage, under voltage, low current grounding system ground fault protection, as well as inhibit breaking cold load pickup functions. 2. Measurement: measuring three-phase current, three-phase voltage, active power, reactive power, active power, reactive power, peak / valley power, power factor and frequency. 3, the control function: You can achieve local control and remote remote control can also be pre-set according to the action plan; can automatically request line fault location, fault isolation and rapid recovery of non-fault circuit power supply, standby power to achieve automatic switching and other control functions. 4. Communication: You can report via wireless public network or a private communication network failure promptly to the designated officer, running and operating information to support a variety of communication methods and communication protocols; handheld PDA can be achieved by modifying the lever under the given value of the parameter, the controller After issuing the command PDA self-test and self-test feedback to PDA terminals. 5, data logging function: automatically record and store operation, operation and fault information. 6, synchronous switching function: according to the load characteristics, automatically search the zero crossing, and environmental factors affect the discrete adaptive switching parameters to achieve synchronous closing, effectively suppress inrush current and over-voltage operation, particularly suitable for switching capacitor and transformers. 7, intelligent features: a comprehensive analysis of network parameters can be carried out online, online monitoring of performance parameters of the circuit breaker, online programming, can cooperate with distribution automation system master switch for remote control and management of equipment, to achieve local, remote or stratified controlled distribution automation system functions. ▁▁▁▁▁ ━━━━━ three technical characteristics, AB-3S-12 permanent magnet vacuum circuit breakers technical characteristics: A, using magnetic actuation (permanent magnet) institutions so that a significant reduction in parts, significantly reducing the power switch on Small, stable and reliable, no regular maintenance; B, imported outdoor epoxy resin as outer insulation material, light weight, long life of more than 15 years, good weather resistance, no oil, no SF6, comply with environmental requirements; C, with a automatic reclosing function effectively avoid blackouts due to transient faults caused by such distribution network in the absence of the master with the situation, can also auto-complete fault isolation and restore power capabilities. D, self-powered (solar power supply and CT), no external power supply can achieve sub-closing operation. E, easy to operate, either manually open / close operation, but also a wireless remote control, remote control distance is more than 50m. F, using synchronous switching technology, synchronous switching circuit breaker effectively suppress inrush current and over-voltage operation. G, built-in voltage and current sensors, no external PT and CT can accurately extract the measurement, protection features required for various electrical amount. H, flexible communications, support GSM SMS, support GPRS, CDMA universal wireless services to support a variety of communication fiber optic, twisted pair, wireless carrier, and support for multiple communication protocols. I, professional power management module provides two-way power line (AC / DC 100 / 220V) automatic switching function, but also has a professional battery management functions. J, the control system user-friendly, all-Chinese system, parameter settings easy and fast. K, fast switching over if you need additional customer requirements stainless steel casing (300 yuan) R 'is not afraid of confinement, afraid of the mass ratio, however, welcome to negotiate the purchase price. ▁▁▁▁▁▁ ━━━━━━ four main technical parameters, AB-3S-12 permanent magnet vacuum circuit breaker main technical parameters: ● Rated voltage: 12kV ● Rated current: 630 (1250) A ● Rated short-( 1min) power frequency withstand voltage: 42kV ● Rated lightning impulse withstand voltage: 75kV ● rated short-circuit breaking current: 20kA ● rated short-circuit current (peak): 50kA ● thermal current (3s): 20kA ● dynamic current (peak): 50kA ● rated short-circuit current breaking times: 30 times ● Rated frequency: 50Hz ● mechanical cycles: 10000 ● main circuit resistance: ≤120 uΩ ● Current sensor ratio: 30 ~ 1250/1 ● Power supply voltage + 24V ● creepage distance ≥31 mm / kV ● Operating temperature: -40 to + 70 Weight: 90 + 27kg ▁▁▁▁▁▁ ━━━━━━ five key search terms, the following are searching AB-3S Model Keywords are as follows: AB-3S-12 / 630-20 AB-3S-12 / 630-25 AB-3S-12 / 1000-20 AB-3S-12 / 1000-25 AB-3S-12 / 1250-20 AB -3S-12 / 1250-25 AB-3S-12 vacuum circuit breaker AB-3S -12 Quick permanent magnet vacuum circuit breaker AB-3S-12 phase permanent magnet vacuum circuit breaker AB-3S-12 outdoor high-voltage vacuum circuit breaker AB -3S-40.5 fast vacuum breaker AB-3S-40.5 outdoor high-voltage vacuum circuit breaker ▁▁▁▁▁▁ rapid transit far recommended products ━━━━━━ [pushing intelligent products] ZW20-12 ZW20-12 / 630 -20 ZW20-12 / 630-25 ZW20-12F ZW20-12F / 630-20 ZW20-12F / 630-25 ZW32-12 ZW32-12G / 630-20 ZW32-12G / 1250-20 ZW32-12M / 630-20 ZW32-12MG / 630-20 ZW32-12M / 1250-20 ▁▁▁▁▁▁▁▁ ━━━━━━━━ six passers-by far Electric Co.
