Xi'an AB-3S-12 permanent magnet intelligent controller outdoor vacuum circuit breaker

Xi'an permanent magnet intelligent controller outdoor vacuum circuit breaker
. Series outdoor high-voltage permanent magnet
Vacuum
circuit breaker is a brand-new design that our company combines advanced domestic and foreign technologies, draws on the strengths of others, and adopts a new design A new generation of pole-mounted vacuum circuit breaker developed using high-tech concepts and high-tech means. This product can be used as a switch for the main transformer substation
. '
. The pole-mounted switch of the network can be combined with the controller produced by our company to easily realize control, protection, measurement and communication. It is a device for realizing distribution network automation and miniaturization of substations.
. . 2. . '
. Main functions of outdoor permanent magnet vacuum circuit breaker:
.
. . . Protection function:
. Automatically identify fault current, It can realize functions such as instantaneous current quick-break, limited-time current quick-break, timed overcurrent, directional overcurrent, overvoltage, undervoltage, single-phase grounding protection of small current grounding systems, and cold load start-up suppression breaking.
.
. . . , Measurement function:
.Measure three-phase current, three-phase voltage, active power, reactive power, active power, reactive power, peak. '
. Valley power, power factor and frequency, etc.
.
. .3. Control function:
. It can realize local operation and remote control, and can also act according to the preset plan. It can automatically realize line fault location according to requirements. Isolate faults and quickly restore power supply to non-faulty lines, realizing automatic switching of backup power and other control functions.
.
. . . . Communication function:
. Can report faults, running and operation information 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. By holding the . '
., the fixed value parameters can be modified under the pole. The controller will perform self-test after issuing instructions
. '
. and feedback the self-test information to
. '
.Terminal.
.
. . . ,
.Data recording function
.Automatically record and store running, operation and fault information.
.
. . . ,
.Synchronized opening and closing function
.According to the load characteristics, the zero-crossing point is automatically searched, and the discreteness of the switching parameters and the influence of environmental factors are adaptive to achieve Synchronous opening and closing, effectively suppressing operating overvoltage and closing inrush current, especially suitable for switching capacitors and transformers.
.
. . . ,
. Intelligent functions
. Can conduct online comprehensive analysis of power grid parameters, online monitoring of circuit breaker performance parameters, online programming, and can be connected with the distribution network The automation system master station cooperates to realize remote control management of switch equipment and realize local, remote or hierarchical control distribution network automation system functions.
