Product Description:
When there is a fault in the internal user of the T connection of
the 10KV distribution line, if the fault occurs at the incoming
end, or if the fault occurs inside the incoming switch but the
protection action time limit is not coordinated with the protection
of the substation outgoing switch, it will cause the protection of
the substation outgoing switch to trip. If the nature of the fault
is permanent and the substation fails to coincide, an accident
within a medium voltage user boundary will result in a power outage
of the entire distribution line, and even single-phase grounding
will cause interference to other users. This common ripple accident
in the distribution network will cause unnecessary power outage
losses to other normal users and have a negative impact on a
society highly dependent on power supply.
The boundary load switch is an ideal device for solving the
above-mentioned accidents. The device is installed at the
responsibility boundary point of the 10kV distribution line and can
automatically cut off single-phase grounding faults and isolate
phase to phase short circuit faults. Ensure the electrical safety
of non faulty users and prevent malfunctions
The user's accident has escalated. The boundary load switch control
device is specifically designed for intelligent control of the
boundary switch body. To achieve protection and control functions,
the control device is electrically connected to the switch body
through control cables and aviation connectors, realizing its
protection and automatic monitoring functions. This product is
widely used in urban and rural 10kV distribution user lines.
