Product Description:

The ZW32-12 pole mounted circuit breaker is a robust distribution equipment designed for outdoor applications. It operates at a rated voltage of 12kV and a three-phase AC frequency of 50Hz. This circuit breaker is primarily utilized to interrupt and close the load current, overload current, and short circuit current within electronic systems.

One of the key advantages of the ZW32-12 circuit breaker is its versatility. It finds extensive use in various settings, including substations, industrial and mining enterprise distribution systems, and rural power grids. This makes it a suitable choice for a wide range of protection and control applications.

Additionally, the ZW32-12 circuit breaker can serve as a sectional switch, allowing for efficient power grid operation. By utilizing it in this manner, specific sections of a distribution network can be isolated for maintenance or fault handling purposes.

To enhance its functionality further, the ZW32-12 circuit breaker can be integrated with a controller. This integration enables the achievement of distribution network automation, facilitating remote control, monitoring, and automation of the circuit breaker's operations. This feature contributes to the overall efficiency and reliability of the distribution network.

Controller Introduction:

The controller supports communication via a 485/232 interface, which allows for remote monitoring and control. It can also communicate through optical fiber or wireless connections.

When a heavy switch is detected, the device automatically accelerates the tripping process in the event of a permanent fault. This feature helps protect the system from damage in such situations.

Remote/Manual Closing and Reclosing: The user has the option to remotely or manually close and reclose the circuit. Additionally, if the user forgets to remove the grounding switch when restoring power after repairing a line, the device can accelerate the tripping process to ensure safety.

It allows for the adjustment of three reclosing delay times. This feature provides flexibility in determining the appropriate delay before reclosing the circuit after a fault.

The jump closing circuit of the controller incorporates an anti-misoperation design. It includes an anti-jump function to prevent unintended closure of the circuit.

The controller can distinguish between in-zone and out-of-zone faults based on zero-sequence current. This capability helps identify the location of faults and enables more targeted troubleshooting and maintenance.

Prevention of Misoperation: The remote control switch is designed to prevent misoperations. This design feature ensures that the switch is not accidentally triggered, thereby reducing the risk of unintended actions.
