Overview AB-3S-12 series outdoor high-voltage permanent magnet vacuum circuit breaker is a new generation of column-mounted vacuum circuit breaker newly developed by our company, which integrates advanced domestic and foreign technologies, draws on the strengths of others, adopts new design concepts, and uses high-tech means. . This product can be used as a switch on the 10kV side and 10kV outlet of the main transformer of the 35kV substation, or as a column switch on the distribution network. When combined with the controller produced by our company, it can easily realize control, protection, measurement, Communication is the preferred equipment for realizing distribution network automation and miniaturization of substations.
Conditions of Use
Ambient air temperature: -30C~+60C;
Altitude: no more than 2000 meters;
The wind speed does not exceed 34m/s;
Vibration or ground motion from outside the switchgear and control equipment is negligible; Pollution level: Level IV;
Storage temperature -40C~+85C
Technical features:
1. The magnetic actuation (permanent magnet) mechanism is adopted to greatly reduce the number of components and the closing power. It is stable and reliable and does not require regular maintenance.
2. Imported outdoor epoxy resin is used as the external insulation material. It is light weight, has a lifespan of more than 15 years, has good weather resistance, is oil-free and SF6-free, and meets environmental protection requirements.
3. It has automatic reclosing function, which can effectively avoid power outage accidents caused by instantaneous faults, so that the distribution network can automatically complete fault isolation and restore power supply even without the cooperation of the main station.
4. Self-prepared power supply (powered by solar energy and CT power supply), the opening and closing operation can be realized without external power supply.
5. Easy to operate, it can be operated by manual opening/closing or wireless remote control. The remote control distance is greater than 50m.
6. Use synchronous opening and closing technology to realize synchronous opening and closing of circuit breakers, effectively suppressing operating overvoltage and closing inrush current.
7. Built-in voltage and current sensors can accurately extract various electrical characteristics required for measurement and protection without external PT and CT.
8. The communication method is flexible, supporting GSM short messages, GPRS, CDMA general wireless services, optical fiber, twisted pair, wireless, carrier wave and other communication methods, and supporting multiple communication protocols.
9. The professional power management module can provide automatic switching function of two power incoming lines (AC/DC 100/220V), and also has professional battery management function.
10. The control system has a friendly operation interface, a full Chinese system, and parameter setting is convenient and fast.
11. All stainless steel box, no rust, maintenance-free.
The main function
1. Protection, equipped with functions such as three-stage voltage blocking directional overcurrent protection, inverse time overcurrent protection, zero sequence protection, acceleration protection, overload protection, low-frequency subtraction, low-voltage decoupling and three-phase triple reclosing. 2. Measurement function: measure three-phase current/voltage, active/reactive power, active/reactive power, peak/valley power, power factor and frequency, etc. 3. The control function can realize local operation and remote control, or it can act according to the preset plan. It can automatically realize line fault location, fault isolation and rapid recovery according to the requirements.
It can supply power to the fault line and realize control functions such as automatic switching of backup power supply. 4. Communication function: Fault, operation and damage information can be reported to designated personnel in a timely manner through a wireless public network or a dedicated communication network, and supports a variety of communication methods and communication protocols.
