Review
The ZW□-12 type pole switch with deep integration of primary and secondary equipment, made with a completely sealed and completely insulated design, is mainly designed to perform the functions of sectioning and connecting the main lines of the 10 kV distribution network. This product adopts advanced technologies including current sensors, voltage sensors, capacitor power take-off module and line loss collection module to realize the adaptive comprehensive feeder automation function on site. This function allows the device, without depending on the control center and communication, by detecting short circuits and ground faults, as well as step protection, to adapt to distribution networks with many branches and connections, providing selective protection against line faults. In the event of a short circuit or single-phase earth fault, it can quickly locate and automatically isolate the damaged area in place without affecting the power supply to undamaged areas, which greatly improves power supply reliability. In addition, this product has the functions of calculating active power, reactive power, power factor, frequency and electrical energy, which allows you to monitor the status of the electrical power system in real time, promptly identify possible problems, and thereby more effectively manage and maintain the electrical power system.
Overall, the pole switch with deep integration of primary and secondary equipment is a high-performance intelligent electrical device that can improve the reliability and efficiency of power supply, reduce the damage and maintenance costs of the power system, and is one of the important directions for the development of distribution lines in the future.
Features
1. Safety: deep integration of primary and secondary equipment allows you to reduce the number of auxiliary devices in the primary circuit without increasing the risk of failures; The use of a locking mechanism eliminates the possibility of erroneous remote control due to automation.
2. Efficiency: providing selective shutdown during short circuits (with precise multi-stage selectivity); provision of selective automatic shutdown in case of single-phase ground faults (determination of the location of the fault based on transient processes).
3. Advanced: the use of built-in electronic current and voltage transformers (ECT, EVT); using capacitor power take-off technology to solve the terminal power problem; the case is made using advanced technologies, protection degree IP67; The level of partial discharges of the entire device does not exceed 20 pC.
4. Intelligence: the operation of the terminal does not depend on the control center; Based on machine learning and unique algorithms, it independently evaluates a short circuit or single-phase ground fault and issues commands for action.
5. Ease of use: easy to use, does not require changes to routine operations, does not require additional tools or additional steps, and does not require special training; Factory setting, maintenance is carried out by modular replacement, hot-swappable. This significantly reduces dependence on qualified technicians.
6. Compact: Deep integration of primary and secondary equipment (built-in ECT, EVT) reduces weight by more than 20kg, reduces field installation complexity and improves installation efficiency.
