The power bureau recognizes the 35KV power station high-voltage vacuum circuit breaker Chengdu

ZW7-40.5 outdoor high-voltage vacuum circuit breaker and its matching intelligent control combination. The switch can be opened and closed locally, or remotely controlled through a communication interface. Other information of the circuit breaker can also be transmitted to the control center, and communication channels can be selected from cables, optical fibers, GPRS/CDMA, GSM, etc.

Main mechanical parameters of circuit breakers

Function of boundary switch
Automatically cut off single-phase grounding fault
When a single-phase grounding fault occurs in the user branch line, the boundary switch will automatically open, and users on other branches of the substation and feeder line will not feel the fault;
Automatic isolation phase to phase short circuit fault
When a phase to phase short circuit fault occurs in the user branch line, the boundary switch will immediately open after the substation outgoing line protection trips After the substation overlaps, the faulty line is automatically isolated, and other branch users on the feeder quickly restore power supply (equivalent to an instantaneous fault);
Quickly locate the fault point
After the component boundary switch protection of the user branch line accident is activated, only the responsible user will cut off power, and they will actively report the accident information. The power company can quickly send personnel to the scene for investigation; If the boundary switch is equipped with a communication module, it will automatically report the information to the power management center
Monitor user load
The boundary switch can be equipped with wired or wireless communication accessories to transmit monitoring data to the power management center, achieving remote real-time data monitoring of user loads
It has the function of operating in a ring network and can be applied to ring network lines,
It has metering function, can monitor the voltage, current, frequency and power of the line, and can be remotely transmitted to the management center

Someone has harmonic analysis function, which can provide reliable basis for future power grid pollution control
