Hot sale 11KV safety indoor AC high voltage load breaker switch
Product Description
Load brake switch (LBS) - this is a switching device in the power
distribution network, which is capable to switch off the power
lines under nominal load. It is used to divide the power line into
smaller sections, hence its second designation as a sectionalizer.
If reclosers and LBSs are remotely operated, then during the short
circuit, a manipulation (LBS switching off and on) is done in
cooperation with a recloser in non-voltage pauses (when recloser is
off) to protect the LBS from higher currents than nominal. When the
LBS is manipulated in standard conditions with nominal load, they
occur the arc discharges. Therefore, load break switches are mostly
equipped with various types of arc discharges extinguishers
(spring, oil, vacuum, etc.).
Indicator - it is a device indicating the states of voltage and
current at a given location. The power line is not manipulated and
therefore it is a cheaper device designed to mark an affected area
as accurately as possible, so a repair can be done in the shortest
time.
