Description
(1) technical field
The utility model relates to a kind of water-cooled cable sebific duct device, particularly relates to the good water-cooled cable sebific duct device of a kind of attrition resistance.
(2) background technology
The employed electric arc generator of electric furnace of general steel plant, need to carry high-tension electricity positive and negative extreme to the electric arc generator with cable, and just must make the electric arc generator can produce electric arc, and then melt the metal of carrying in electric furnace by its positive and negative extreme laterally moving.Yet, because the electric arc generator must could produce electric arc with the mobile of its positive pole and negative pole, cable needs to be fixed in respectively on power supply output place and electric arc generator positive and negative extreme with the outstanding state of establishing, and, the required high pressure electric weight of electric arc generator is higher, cable is that one group mode is provided with many normally, is carried enough high pressure electric weight to use for the electric arc generator.
Right cable can produce high heat when carrying high-tension electricity, the dealer produces out the water-cooled cable technology in order to reduce the temperature of cable and research and develop.As shown in Figure 1, general water-cooled cable 1 includes sebific duct 11, and is arranged at cable 12 in the sebific duct 11 and the cooling fluid 13 of filling in sebific duct 11.Utilize cooling fluid 13 can reduce the high temperature that cable 12 is produced when high pressure is switched on.
When four identical water-cooled cables 1 are fitted together (as shown in Figure 1), the termination of water-cooled cable 1 is to be arranged in power supply output place 14 respectively, and (end of the positive and negative electrode of electric arc generator 15 only is shown) among the figure on the electric arc generator 15, and water-cooled cable 1 is fixed in power supply output place 14 partly is to be stationary state, and water-cooled cable 1 is fixed in the part at electric arc generator 15 places can be relative to power supply output place 14 parallel moving.
Yet, because water-cooled cable 1 is to adopt the outstanding mode of establishing to be fixed in 15 of power supply output place 14 and electric arc generators, therefore, when electric arc generator 15 produces electric arc, water-cooled cable 1 must rock along with parallel mobile electric arc generator 15 produces with high-tension electricity conveying influence, cause the sebific duct 11 of adjacent water-cooled cable 1 can produce the phenomenon of mutual abrasion in nearly turning point, and long-term abrasion can cause sebific duct 11 breakages, cause the cooling fluid 13 of filling in sebific duct 11 to spill, if the maintenance personal in time finds the water-cooled cable 1 of blowing out to change this damage of must going ahead of the rest.On the contrary, if the maintenance personal in time do not find, cable 12 can scaling loss and serious industrial hazards takes place.And the blowing out operation of burst type can cause All Jobs on the production line with just stopping, and reduces the overall throughput of electric furnace, and the dealer then must bear to be full of and receive the loss that reduces.
The dealer is in order to take precautions against above-mentioned disappearance, and then the another kind of water-cooled cable 2 as shown in Figure 2 of research and development, its structure design is roughly the same with aforementioned water-cooled cable 1, and in order to prevent that sebific duct 21 from producing abrasion phenomenon mutually when electric arc generator 26 produces electric arc, on sebific duct 21, be arranged with and protect piece 22, each protects piece 22 is to utilize chase 221 to match with C jacket ring 222, and be able to be positioned on the sebific duct 21 firmly and mutually accordingly, so as to can directly not ground, touch by 21 of these a plurality of sebific ducts, prevent to wear away the infringement that phenomenon produces sebific duct 21, and then prolong the useful life of sebific duct 21.And the maintenance personal just can be the normal blowing out maintenance time that electric furnace sets, change produce abrasion protect piece 22 or water-cooled cable 2.
Yet, though this type of water-cooled cable sebific duct 2 can reduce the abrasion phenomenon, but on using, reality still has some disappearances, details are as follows respectively:
1. the locating effect that protects piece is not good:
When being positioned on the sebific duct 21, can influencing because of the cooling fluid in the sebific duct 21 13, and can't sealedly securely be positioned on the sebific duct 21 when protecting piece 22 to utilize C jacket ring 222.And; when electric arc generator 26 produces electric arc; water-cooled cable 2 can produce and rock; protecting piece 22 simultaneously can be subjected to shaking phenomenon and earth gravity effect and produce loosening phenomenon; and down slippage gradually, even concentrate on the minimum point place that is the water-cooled cable 2 that hangs the state that swings, like this; protect the effectiveness that 22 forfeiture protections of piece sebific duct 21 avoids wearing and tearing, 2 relevant issues such as easy abrasion damage that can produce equally of this water-cooled cable as aforementioned water-cooled cable 1.
2. the abrasion situation is more serious:
Just protecting piece 22 at last can not produce sliding phenomenon, but, protect piece 22 after mutual abrasion a period of time, the C jacket ring 222 that originally is located in the chase 221 can be exposed to the surface of protecting piece 22 gradually, the 222 directly possible and sebific duct 21 generation frictions of C jacket ring, add that C jacket ring 222 is that hard metal material is made, even the abrasion phenomenon of aggravation sebific duct 21.In addition, as shown in Figure 3, protect on the piece 22 because of 221 protuberances that form relatively of chase can embed in the chase that protects piece 22 221 of position on another sebific duct 21, the protuberance that protects piece 22 is when embedding or break away from chase 221, can be subjected to strong friction, cause that to protect piece 22 abrasion more serious.
In addition; the high hot liquid metal that electric furnace melted of steel plant can sputter outside the electric furnace when operation; and high hot liquid metal with can become tiny Mars after air contacts; because water-cooled cable 2 is suspended near the electric furnace usually; tiny Mars gathers in the chase 221 when dropping easily or protects on the right angle of piece 22 ora terminalis; hiding causing protected piece 22 or sebific duct 21 burnings and the crisis of initiation fire, even causes more serious disaster.
3. the thickness that protects piece 22 tear-and-wear allowances is lower:
Because sebific duct 21 internal causes of water-cooled cable 2 are filled with cooling fluid 24, its overall weight is quite big, add that again water-cooled cable 2 is to adopt the outstanding mode of establishing to be arranged in 26 of power supply output place 25 and electric arc generators, therefore, certainly will limit to some extent for the overall weight of water-cooled cable 2.Yet the setting of protecting piece 22 not only can increase the weight of the weight of water-cooled cable 3, and the setting of C jacket ring 222 more can reduce the thickness that protects piece 22 tear-and-wear allowances.
