The invention discloses a
bulb replacement device for a high-
voltage chamber of a
transformer substation. The
bulb replacement device comprises an insulation operating rod, a circular air
pipe arranged in the insulation operating rod, an inflating air sac communicated with the lower end of the air
pipe, a hollow clamping jaw arranged at the upper end of the insulation operating rod and communicated with the air
pipe, and an auxiliary air sac. The auxiliary air sac is connected to the lower end of the insulation operating rod through a connecting soft belt, both the inflating air sac and the auxiliary air sac are provided with air holes, a first plug is arranged in the air hole of the inflating air sac, an air outlet pipe is hermetically connected to the periphery of the air hole of the auxiliary air sac, a second plug is arranged in the air outlet pipe, and the outer
diameter of the air outlet pipe is equal to the inner
diameter of the air hole of the inflating air sac. The insulation operating rod is provided with an air sac switch. Air can be naturally exhaust to loosen a
bulb without human interference, operation is convenient and
safety coefficient is high. The auxiliary air sac is used for inflating the inflating air sac, so that the bulb replacement device is convenient and quick, is time saving in bulb replacement and free of carrying another inflating device and has the advantages of simple and compact structure, convenience in use and the like.
