Abstract
An electric heating tube is composed of the heating wire, the powder, insulation material envelope, the inner tube, the heat conducting oil, the outer tube, the insulated seal housing and the electrode, in order to raise the dielectric strength of the electric heating tube. The heating wire is built in the inner tube and leaded out from the electrode in the end of the inner tube. The powder insulation material is filled into between the inner tube and the heating wire as well as the electrode. The insulated seal housing fixed the ends of the inner tube and the outer tube. The heat conducting oil is filled into the cavity between the inner tube and the outer tube. The heat quantity of the heating wire through the powder insulation material, the inner tube, the heat conducting oil and the outer passes to outside.
Description
Affiliated technical field
The present invention is a kind of electrothermal device, is a kind of electrothermal tube.
Background technology
Existing electrothermal tube is made up of metal tube, heating wire, powder insulation material, electrode, and heating wire is arranged in the metal tube, fills powder insulation material in the pipe, as silica flour, magnesia powder etc.And draw by electrode, the heat that heating wire sends is delivered to metal tube by the insulating material of powdery, and is distributed by it, thereby realizes the purpose of heating, but material moisture-sensitive such as magnesia powder, silica flour and reduce insulation property causes electric leakage.
Summary of the invention
The object of the invention is to provide a kind of isolation electrical heating pipe of high-insulation.
The solution of the present invention is: adopt heating wire, powder insulation material, interior pipe, conduction oil, outer tube, insulated enclosure cover, electrode to form the isolation electrical heating pipe, heating wire is embedded in the interior pipe, draw by the electrode that is located at the inner tube mouth, fill powder insulation material between interior pipe and heating wire and electrode, the outer sheathed outer tube of interior pipe, the port of inner and outer pipe is fixing by the insulated enclosure cover, pours into conduction oil in the cavity volume between inner and outer pipe.Utilize the heat conductivility of conduction oil, the heat that heating wire is dispersed transmits to the outside through powder insulation material, interior pipe, conduction oil, outer tube, realizes heating purposes.
Advantage of the present invention is: by powder insulation material, conduction oil two class F insulations, improved the dielectric strength of electrothermal tube, even powder insulation material produces electric leakage, the buffer action of conduction oil also can make outer tube be in a safe condition.
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings below.
Accompanying drawing is a structural representation of the present invention.
1 is heating wire among the figure, the 2nd, and powder insulation material, the 3rd, interior pipe, the 4th, conduction oil, the 5th, outer tube, the 6th, insulated enclosure cover, the 7th, electrode.
Heating wire (1) is embedded in the interior pipe (3), draw by electrode (7), electrode (7) is located at two ports of interior pipe (3), fills powder insulation material (2) in the interior pipe (3), and heating wire (1) electrode (7) is fixed by compressing by this powder insulation material (2).Interior pipe (3) is set in the outer tube (5), and is fixing by the insulated enclosure cover (6) at two ends, perfusion conduction oil (4) in the cavity volume between inner and outer pipes, and conduction oil is selected heat-conducting silicone grease, silicone oil or transformer oil for use, has good heat conductive insulating performance.
Heating wire (1) energising back heating, heat is delivered to interior pipe (3) via powder insulation material (2) as silica flour, magnesia powder etc., is delivered to outer tube (5) by interior pipe (3) through conduction oil (4) again, thereby to the outside heat radiation, to realize heating purposes.
Owing to adopted the double insulation of powder insulation material (2), thereby the dielectric strength of electrothermal tube improved, improved fail safe with conduction oil (4).
Claims (1)
- A kind of isolation electrical heating pipe, form by heating wire, powder insulation material, interior pipe, conduction oil, outer tube, insulated enclosure cover, electrode, it is characterized in that: heating wire is embedded in the interior pipe, draw by the electrode that is located at the inner tube mouth, fill powder insulation material between interior pipe and heating wire and electrode, the outer sheathed outer tube of interior pipe, the port of inner and outer pipes is fixing by the insulated enclosure cover, pours into conduction oil in the cavity volume between inner and outer pipes.
