Bulb replacement device for high-voltage chamber of transformer substation

Abstract

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.

Description

[0001] technical field [0002] The invention relates to the field of electric power maintenance auxiliary equipment, in particular to a light bulb replacement device for a high-voltage room of a substation. Background technique [0003] In the high-voltage room of the substation, due to the long-term overload of lighting, the bulbs are often burned out. The roof of the high-voltage room is very high. Once a light bulb is burned out, a ladder is needed to replace the light bulb. However, in the high-voltage room, according to the electrical code, ladders are not allowed to be carried casually, so it is very difficult to replace light bulbs in the high-voltage room of the substation. [0004] Patent CN203521374U discloses a light bulb picking device for substation high-voltage chambers. The picking device includes an insulating operating rod and a gas pipe located inside the insulating operating rod. The lower end of the gas pipe communicates with the inflatable air bag, a...

Problems solved by technology

[0005] The above scheme overcomes the problem of inconvenient use of ladders for replacing bulbs in the high-voltage room of the substation, but it is not equipped with any switch to control the opening and closing of the airbag. When the bulb is loosened, due to the airtight space where the gas is located, the air in the original jaws will not automatically return to the air bag to make the jaws loosen the bulb, requiring human intervention. It is impossible to implement human intervention to return the air in the jaws to the airbag. In addition, human intervention is easy to break the bulb, and the broken bulb may scratch the operator. The best way is to make the space where the gas is no longer airtight. In the airbag or The gas outlet is set at other positions to discharge the gas, and this method also has a problem: after the old bulb is removed, because the inflatable air bag has been deflated, it needs to be re-inflated when the new bulb is put in to make the hollow jaws clamp the new bulb. Bulb, this process requires the use of an inflator to re-inflate the inflatable air bag, which is very inconvenient to use and wastes time, and it is necessary to carry the inflator to the site where the bulb is replaced

In short, it is very inconvenient to use the bulb removal device in the above solution
