ZW32M-12 permanent magnet mechanism intelligent vacuum circuit breaker, (user boundary, branch switch)

Overview
New problems faced by the distribution network:
1. The failure rate of branch lines has significantly increased after the improvement of the main line;
2. Due to the failure of a single user on the branch line and improper protection coordination, the entire feeder line is affected by power outages and liability disputes arise;
3. The grounding selection device of the substation cannot meet the requirements of quickly finding grounding faults;
4. The delay caused by multi-level line protection deteriorates the operating environment of the power grid.
ZW32M-12 outdoor vacuum circuit breaker is an ideal equipment to solve the above problems.

Functional Features
Integrated zero sequence grounding protection: It has both zero sequence voltage and zero sequence current protection. When a single-phase grounding or phase to phase short circuit fault occurs in the user branch line, the boundary switch will automatically trip, without affecting the power supply of the substation to other branch lines on the feeder line;  
Parameter settings: The overcurrent and quick break protection values are continuously adjustable, and various parameters can be set according to the condition of the line;  
Vacuum permanent magnet switch: Compared with spring mechanism, it has the characteristics of simple structure, reliable action, and long service life;  
Stainless steel casing: Made of stainless steel shell, with beautiful appearance and long service life;  
Intelligent control device: integrating protection and control, it can read data, set parameters, and view operating status through GSM/GPRS remote communication, and can also be set locally, view parameters, and remotely operated through Bluetooth handheld devices;
Characterized by strong anti-interference ability and safe and reliable operation;  
Cable connection with aviation plug: Various components are connected through aviation plug, which is simple, convenient, and easy to maintain;
GSM/GPRS wireless communication: Configuring the GSM/GPRS wireless communication module can transmit monitoring data to the power management center, achieving real-time data monitoring of user loads; Conveniently and quickly locate the fault point.
