Brief description of the drawings
Fig. 1 is the structure of an embodiment of the low ablation tubular pole of high pressure of the present inventionSchematic diagram.
Detailed description of the invention
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, knot belowClosing accompanying drawing is described in detail the specific embodiment of the present invention.
Refer to Fig. 1, the invention provides the low ablation tubular pole of a kind of high pressure, comprising: electricityUtmost point inner sleeve 1, it is established backup electrode material by electric arc heated and makes, and is used to form electric arc; ElectrodeOvercoat 2, it is set in the outside of described electrode inner sleeve 1, and limit between described electrode inner sleeve 1Make a toroidal cavity; Field coil 4; And insulating support, it is arranged on described annularIn cavity, be made up of insulating materials, described insulating support comprises inner support and support arm; Wherein,Described inner support is set in the outside of described electrode inner sleeve, coaxially arranges with described electrode inner sleeve,Described field coil 4 is wrapped on described inner support 3, and described support arm 5 is set in described magneticOn field coil, to isolate described field coil, actual is by field coil and described electrode inner sleeveAnd described electrode jacket is isolated. Field coil 4 is built in outside electrode inner sleeve 1 and electrodeBetween cover 2, thereby make the magnetic field producing cover whole electrode, strengthen electric arc arc root in electrodeThe rotation putting, has reduced the ablation of electrode inner sleeve. Above-mentioned insulating support improves to field coilSupport, field coil and other structures are all separated out simultaneously, realize effectively insulation.
In one embodiment, the present invention also comprises: coolant jacket, it is set in described electrodeInside put, between described electrode inner sleeve and described inner support, described toroidal cavity is separatedBecome the first annular space and the second annular space, wherein, described in described the first annular space is served as reasonsThe space that electrode inner sleeve and described coolant jacket limit, described in described the second annular space is served as reasonsThe space that electrode jacket and described coolant jacket limit; On described electrode jacket, feed liquor is setHole and fluid hole, described inlet opening is communicated to one end of described the first annular space, and described firstThe other end of annular space is communicated with described the second annular space, and described fluid hole is communicated to secondAnnular space, thus limit a flow path for cooling fluid: and described flow path is first to flow intoDescribed the first annular space, then flow into described the second annular space, then flow out to outside described electrodeOutside cover.
In the time that a coolant jacket 6 is between electrode inner sleeve 1 and insulating support (as Fig. 1 instituteShow), the erection sequence of tubular pole of the present invention is: first support arm 5 is fixed on to electricityThe inwall of utmost point overcoat 2, inner support 3 is fixed on the outer wall of coolant jacket 6, then by magnetic field lineCircle 4 is wrapped on inner support 3, afterwards coolant jacket 6 is embedded in electrode jacket 2 (realBorder is namely loaded to inner support support arm inside), finally electrode inner sleeve 1 is encased in coldBut in liquid cover 6.
