Abstract
The invention discloses a paper-covered wire anti-damage device, which comprises a paraffin pot and a roller, wherein a heating device for melting paraffin is arranged in the paraffin pot; the lower part of the roller is immersed in molten paraffin in the paraffin pot; and the upper part of the roller is in close contact with a wide face on the lower side of a paper-covered wire. According to the paper-covered wire anti-damage device, the friction coefficient of the paper-covered wire is greatly reduced and the paper-covered wire cannot be damaged easily during friction by changing the friction coefficient and increasing a paraffin coating melting process, and meanwhile, the insulation performance and the toughness of outer covering insulating paper are improved. The paper-covered wire anti-damage device is suitable for ultrahigh voltage transformer coils of 750 KV and megavolt.
Description
Technical field
The present invention relates to a kind of process equipment of power transmission and transformation corollary equipment, specifically a kind of paper bag lead breakage-proof device.
Background technology
At present, the high-power transformer coil mainly uses paper bag compound wire and the two class coilings of paper bag transposed conductor.The paper bag compound wire is by bare copper flat wire outsourcing insulating paper, and then formed by two or many compound outsourcing insulating papers; Then the outsourcing insulating paper forms the paper bag transposed conductor through replacing again by many enameled sheet wires.Lead outsourcing insulating paper is mainly in order to insulate and to dispel the heat, and can improve the bulk strength of lead.
The paper bag lead can produce between lead and rub, is offset, collides with in production, transportation, coiling, running, and the outsourcing insulating paper is easy to breakage, tears.Because the friction between lead is inevitable, the surface of insulating paper is comparatively coarse, so coefficient of friction is higher, in case skew friction between lead takes place, the outsourcing insulating paper is easy to discerp, weares and teares.When particularly the lead yield strength is big, outsourcing insulating paper even all scraped and wipe, the copper conductor of the inside all sustains damage, and all there are hidden danger in insulation property, bulk strength.
Summary of the invention
For overcome that existing insulating paper surface exists because friction causes the phenomenon of breakage, the purpose of this invention is to provide a kind of paper bag lead breakage-proof device, this device is started with from changing coefficient of friction, increased to melt and be coated with ceroplastic, paper bag lead coefficient of friction is greatly reduced, be not easy breakage during friction, insulation property, the toughness of the insulating paper of outsourcing simultaneously make moderate progress.
The objective of the invention is to be achieved through the following technical solutions:
A kind of paper bag lead breakage-proof device, it is characterized in that: this device comprises paraffin jar and roller, is provided with the heater that paraffin is melted in the paraffin jar; The bottom of roller is immersed in the interior thawing paraffin of paraffin jar, and the top of roller closely contacts with wide of the downside of paper bag lead.
Among the present invention, be provided with heater at the wall of paraffin jar, this heater is heating wire.The middle part of roller is immersed in the thawing paraffin in the paraffin jar with the lower part.
The present invention greatly reduces paper bag lead coefficient of friction to the processing of waxing of the bare copper flat wire after wrapping paper and handling, and is not easy breakage during friction.
Among the present invention, described waxing is handled: be coated with the last layer liquid paraffin at wide face of paper bag lead, wax liquid infiltrates the outsourcing insulating paper rapidly, and at the smooth cere of insulating paper surface formation one deck, paper bag lead coefficient of friction is greatly reduced, be not easy breakage during friction, insulation property, the toughness of the insulating paper of outsourcing simultaneously make moderate progress.
The present invention utilizes the waxing processing to make outsourcing insulating paper any surface finish lubricated, greatly reduce coefficient of friction, effectively improved the outsourcing insulating paper damaging problem that in transportation, coiling, running, rubs, insulation property and the toughness of the bulk strength of lead, outsourcing insulating paper all improve, and have improved the product quality of paper bag lead.The present invention is applicable in 750KV and the megavolt coils of high-voltage transformers.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of paper bag lead breakage-proof device is seen Fig. 1, and this device comprises paraffin jar 1 and roller 2, is provided with the heater that paraffin is melted in the paraffin jar, and this heater is heating wire, is arranged on the wall of paraffin jar.Heating wire makes paraffin 4 be melted into liquid, and the middle part of roller is immersed in the thawing paraffin 4 in the paraffin jar with the lower part, and the top of roller closely contacts with wide of the downside of paper bag lead 3.
By the present invention to the processing of waxing of the bare copper flat wire after will wrapping paper and handling.The heating paraffin that is placed in the jar is melted, by roller the liquid paraffin in the jar is coated on wide of paper bag lead, wax liquid infiltrates the outsourcing insulating paper rapidly, and at the smooth cere of insulating paper surface formation one deck, paper bag lead coefficient of friction is greatly reduced, be not easy breakage during friction, insulation property, the toughness of the insulating paper of outsourcing simultaneously make moderate progress.Greatly reduce coefficient of friction, effectively improved the outsourcing insulating paper damaging problem that rubs in transportation, coiling, running, insulation property and the toughness of the bulk strength of lead, outsourcing insulating paper all improve, and have improved the product quality of paper bag lead.
