Abstract
The utility model relates to a cooling ventilating fan field especially relates to a high-power electric fan, including the power cable, its characterized in that, the power cable is four-core cable, and wherein three-core is three-phase power cord, a core and is the earth connection, and the earth connection line tip links to each other with the electric fan shell. The ground wire is a rubber sheath copper wire, and the section of the wire core is not less than 5mm2. Compared with the prior art, the beneficial effects of the utility model are that: the four-core cable is adopted to combine the power supply and the grounding of the electric fan into a whole, so that the working site is neat and attractive, and the grounding effect can be reliably ensured.
Description
Technical field
The utility model relates to cooling ventilation fan field, relates in particular to a kind of large power, electrically fan.
Background technique
Blast furnace is high temperature, high coal gas zone, and the worker should bear the baking of high temperature when carrying out manufacturing operation, also will be in the face of the danger of gas poisoning.The large power, electrically fan is to solve high temperature and the most effective equipment of dilution coal gas.In order to guarantee site safety, electric fan all uses the independent grounding line, and general ground wire adopts wire rope, and its shortcoming is easy oxide breakage, and ground wire and power line make the working site disheveled neat, and people easily stumbles.
Summary of the invention
The purpose of this utility model is to provide a kind of large power, electrically fan, overcomes the deficiencies in the prior art, and ground wire and power line are united two into one, and makes on-the-spot neat appearance, earthing effect reliable.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of large power, electrically fan comprises power cable, and described power cable is quad, and wherein three cores are that three-phase power line, a core are ground wire, and the ground wire end links to each other with the electric fan shell.
Described ground wire is the rubber sheath copper cash, and the core cross section is not less than 5mm
2
Compared with prior art, the beneficial effects of the utility model are: adopt quad that power supply and the ground connection of electric fan are united two into one, both guaranteed the working site neat appearance, and again can the Reliable guarantee earthing effect.
