Inflatable type replacing device for high-voltage chamber bulb

Abstract

The invention discloses an inflatable type replacing device for high-voltage chamber bulb. The inflatable type replacing device comprises an insulation operating rod, two inflatable air bags, an air pipe and a hollow clamping jaw. The air pipe is arranged in the insulation operating rod. The hollow clamping jaw is arranged at the upper end of the insulation operating rod and further communicated with the air pipe. The inflatable air bags are composed of hollow circular tubes and air bag bodies. The air bag bodies are respectively in sealing connection with the rear ends of the hollow circular tubes. Air holes are formed in the air bag bodies. First plugs are respectively arranged in the air holes. A second plug is plugged in the front end of the hollow circular tube of one inflatable air bag. The hollow circular tube of the other inflatable air bag is in sealing connection with the lower end of the insulation operating rod in a detachable mode. Air bag switches are respectively arranged in the hollow circular tubes. The inflatable type replacing device is capable of naturally exhausting to loosen the bulb, free of manual interference, convenient to operate and high in safety factor. With two inflatable air bags adopted to inflate, the replacing device is convenient and rapid to replace the bulb with time saved and further is free of carrying additional an inflation device, and has the advantages such as simple and compact structure and convenience in use.

Description

[0001] technical field [0002] The invention relates to the field of electric power maintenance auxiliary equipment, in particular to an inflatable high-voltage chamber bulb replacement device. 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, and the upper end...

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
