Outdoor Distribution HV Pole Mounted Circuit Breaker With Controller Of Smart System Matching With Outdoor Hookstick
Product Description:
ZW32-12(F) high voltage pole mounted circuit breaker is an outdoor distribution equipment with a rated voltage of 12kV and a three-phase AC frequency of 50Hz. It is mainly used for breaking and closing the load current, overload current, and short circuit current in electronic systems. It is suitable for protection and control in substations and industrial and mining enterprise distribution systems, as well as for frequent operations in rural power grids. It can also be used as a sectional switch for power grid operation. With the installation of a controller, the ZW32-12 automatic recloser electrical sectionlizer can seamlessly integrate into power grid operations. It enables remote monitoring, control, and automation of the distribution network, optimizing system performance and facilitating efficient energy management.
The GW9-10 operated hookstick is a type of electrical switch used to isolate a section of an overhead power transmission line for maintenance or repair. It is typically used in high voltage electrical systems, such as those used by power utilities to transmit electricity over long distances.
The hookstick is mounted on an overhead structure, such as a transmission tower or pole, and is designed to withstand the harsh environmental conditions encountered in outdoor electrical systems. It features a vertical, or up-and-down, motion to engage or disengage the switch contacts, which are typically made of copper or other conductive materials.
The hookstick is designed to provide a visible break in the transmission line, allowing maintenance personnel to safely work on the line without risk of electrocution or damage to equipment. It is often used in conjunction with other safety devices, such as grounding switches and surge arrestors, to protect the electrical system and the people working on it.
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.
