12kV 50Hz High Voltage Vacuum Circuit Breaker GB1984-2003 With Controller Outdoor Circuit Breaker With Hookstick Switch

12kV 50Hz High Voltage Vacuum Circuit Breaker GB1984-2003 With Controller Outdoor Circuit Breaker With Hookstick Switch

 
Product Description:

 
The ZW20-12(F) Automatic Vacuum Circuit Breaker is a versatile and intelligent device that combines the functions of a vacuum breaker, vacuum load switch, recloser, and sectionalizer. It is designed for use in 10kV and 13kV distribution networks, specifically in city and rural power grids.
The main components of the ZW20-12(F) circuit breaker include a vacuum breaker, CH-40 controller, and an external voltage transformer. The vacuum breaker is responsible for interrupting and making electrical circuits, while the CH-40 controller provides intelligent protection and control functions. The external voltage transformer helps in accurate voltage measurement for control and monitoring purposes.

GW9-10 hookstick switch is an electrical switch that is designed to isolate a section of an electrical network or system from the rest of the system for maintenance or repair purposes. It is typically used in high voltage power transmission and distribution systems.

The switch is designed to open and close under normal or abnormal conditions, such as a fault or overcurrent. When the switch is open, it physically disconnects the section of the system from the rest of the network, preventing the flow of electricity to that section.

High voltage disconnect switches are typically designed to operate at voltages between 600 volts and 765,000 volts, and they can be operated manually or automatically. They are typically installed in substations or on power poles, and they are an important component of the electrical grid infrastructure.

Characteristics of the controller:

Intelligent terminal controllers have functions such as protection, automatic control, inspection/query, communication, and software management.

1.Comprehensive Functionality:

• Perfectly implement various functions such as circuit protection, remote control, alarm, and remote monitoring.

2.Low Cost and Practicality:

• No need for any communication hardware investment in GSM networks. Simply purchase a SIM card and activate SMS services.

3.Multiple Security Measures:

• Use designated mobile phones, information encryption, password verification, and other security measures.

• The GSM module can specify a mobile number and only accept commands from the bound phone.

• Communication messages for remote control and other commands are encrypted.

• Follows a pre-set-confirm-execute-verify remote control method to ensure the security of system control and prevent misoperations.

4.Simple System Configuration:

• No need to install any communication lines or debug communication lines.

• Simply install the SMS intelligent monitoring terminal correctly, insert the SIM card, set the designated mobile number, and the system will start running.

5.Mobile Monitoring Anytime, Anywhere:

• Real-time monitoring and viewing can be done in any location with a signal, without the need for personnel to be stationed for monitoring.
