Description
Technical field
This utility model relates to a kind of outdoor load switch.
Background technology
It is generally equipped with simple arc-control device, but it is relatively simple for structure.Figure is a kind of air pressing type high voltage load switch, and its work process is: during separating brake, and under the effect of tripping spring, main shaft turns clockwise, and on the one hand makes piston move up by slider-crank mechanism, by gas compression；On the other hand by the drive system of two set quadric chain compositions, making main switch cutter first open, then promote arc extinguishing plug-in strip to make arcing contact open, the compressed air in cylinder blows out electric arc by spout.On-load switch is a kind of device for switching between chopper and disconnecting switch, has simple arc-control device, can cut off rated load current and certain overcurrent, but can not cut off short circuit current.The operation principle of high voltage load switch is similar to chopper.It is generally equipped with simple arc-control device, but it is relatively simple for structure.Figure is a kind of air pressing type high voltage load switch, and its work process is: during separating brake, and under the effect of tripping spring, main shaft turns clockwise, and on the one hand makes piston move up by slider-crank mechanism, by gas compression；On the other hand by the drive system of two set quadric chain compositions, making main switch cutter first open, then promote arc extinguishing plug-in strip to make arcing contact open, the compressed air in cylinder blows out electric arc by spout.
