GW9 Outdoor LBS AC high voltage isolating switch Vacuum Load Break
Switch
Overview: The GW9-12 outdoor isolation switch is a single-phase AC 50Hz
high-voltage switching device.It is used in 10KV power systems for
turning on or off the power supply in the case of voltage and no
load. This product is a single-break vertical open structure,
unicorn isolation switch pillar insulator is installed on their
respective base frame, mainly by the base, pillar insulator,
leading electrical circuit part, self-locking device and so on.The
gate-type structure is used to split the gate to cut off and close
the line.Each phase knife switch consists of two conductive blades,
the blade is equipped with compression springs on both sides,
adjusting the height of the spring can obtain the contact pressure
required to the knife switch.When the switch on and off,the
operating mechanism part of the insulated hook rod is used, and the
knife switch has its own locking device. When the isolation switch
is separated with an insulated hook rod operation, the insulation
hook stick buckles the isolation switch lock hook, pulls the lock
hook to the direction of the separation gate, unlocks the
self-locking device and drives the connecting conductive plate
rotation to achieve the split-gate action, when the lock is closed
by the insulating hook rod against the isolation switch hook drives
the shaft rotation, so that the connected conductive plate turns to
the closed position, at this time the self-locking device locks the
isolation switch in the closed position. This type of isolation
switch can be mounted on a strut, wall, ceiling, crossbar or metal
frame, or can be mounted upright or obliquely, however the mounting
position should be trending down when the tentacle is open. Service environment:1)Altitude: ≤1000m; 2)Environment temperature:-30～+40℃,Alpine
region≤-40℃; 3)Wind pressure:≤700Pa(Equivalent to wind speed of
34m/s); 4)Earthquake intensity:≤8 degrees; 5)No frequent and
violent vibration site; 6)General installation sites should be free
of gases, vapors, chemical deposits, salt sprays, dust and other
explosive, aggressive substances that seriously affect the
insulation and conductivity of isolated switches.Anti-fouling type
is suitable for filthy areas, but should not cause fire and
explosive substances. |
