In the power distribution network, the effective integration of primary equipment and secondary equipment has always been the focus of technological development. DX-WPS100-GZ03/PTS is a new type of primary and secondary fusion complete set of column-mounted circuit breaker fault ranging device, which is an outstanding representative of this technical concept. It not only retains the basic functions of traditional circuit breakers, such as fault isolation and line protection, but also adds high-precision fault ranging and localization functions, as well as intelligent fault handling mechanism, which belongs to the fault ranging type of one and two fusion column-mounted circuit breakers, and provides a strong guarantee for the safe and stable operation of power distribution network.

I. Technical background and advantages

In traditional distribution networks, there are differences between primary and secondary equipment in terms of interface design and communication protocols, resulting in poor equipment compatibility and difficulty in realizing seamless connection. The new primary and secondary fusion complete set of column-mounted circuit breaker fault ranging device of DXN Wisdom Technology realizes the positioning of various types of faults on distribution network lines through the integration of traveling wave ranging technology.

II. Features and functions of the device

High-precision fault ranging:Using traveling wave ranging technology, through the special traveling wave transformer, high-frequency sampling chip and high precision Timing module for the acquisition and analysis of high-frequency traveling wave signals, to achieve the positioning of various types of faults on the distribution network lines, in which the traveling wave current sensor frequency response range of the traveling wave current sampling rate in the 1kHz ~ 1MHz; ≥ 1MHz; current sensor frequency response range: 20Hz ~ 1kHz fault current measurement range; synchronization clock scale accuracy of ≤ 0.1us.

Intelligent Troubleshooting:The device is equipped with a comprehensive data acquisition capability, including the measurement of three-phase currents, zero-sequence currents, and the Real-time acquisition of three-phase phase voltage or one line voltage on each side of the switch and zero sequence voltage. Upon detecting a fault, the device is able to respond quickly and directly trigger a trip operation to remove the faulty part, ensuring the safety and stability of the power system.

Depth integration of primary and secondary equipment:The device realizes the deep integration of primary equipment and secondary equipment, which not only retains the basic functions of traditional circuit breaker, but also adds functions such as fault ranging, location and intelligent processing. The device not only retains the basic functions of traditional circuit breakers, but also adds new functions such as fault ranging, localization and intelligent processing, which enhances the self-healing capability of the power grid.

Flexible Operation and Low Energy Consumption:Integrated with the electric operation function, and supports manual operation mode, realizing the flexible operation mode. Switching. At the same time, the instantaneous power of electric operation is controlled within a certain range, which not only ensures the fast response of operation, but also effectively reduces energy consumption.

III. Application scenarios and benefits

The new primary and secondary fusion complete set of column-mounted circuit breaker fault ranging device is widely used in the sectionalization, liaison, branching and demarcation of power distribution lines. Its high-precision fault ranging and localization function can quickly locate the fault point, shorten the fault processing time and reduce the scope of power outage. At the same time, the intelligent fault handling mechanism can detect potential problems in advance and take measures to prevent the occurrence of faults, improving the reliability and safety of the power grid, welcome to consult Shenzhen Dingsin Wisdom Technology at any time!
