Abstract
The invention provides an optical fiber electric heat tape and relates to an electric heat tape, and the optical fiber electric heat tape can be used for solving the problem that the fault point of a very long electric heat tape is difficult to accurately judge. The optical fiber electric heat tape comprises an electric heat tap body, an optical fiber (5), an inner sheath (2), a shielding layer (3) and an outer sheath (4), wherein the optical fiber (5) is arranged along the length direction of the electric heat tape body (1) and props against the electric heat tape body (1); the inner sheath (2), the shielding layer (3) and the outer sheath (4) are sequentially coated on the outer walls of the electric heat tape body (1) and the optical fiber (5) from inside to outside; once a certain point on the electric heat tape has a fault, the optical fiber can monitor the temperature change of the point in real time, and the change of reflected signal receiving time can accurately report the position of the fault point, so that maintenance can be organized quickly and conveniently, and the electric heat tape is restored to normal operation within minimum duration. The optical fiber electric heat tape can be used for heating conveying pipelines and storage tanks in the industries of buildings, steel, power and the like.
Description
Technical field
The present invention relates to a kind of ribbon heater.
Background technology
The ribbon heater can be divided into series connection and two kinds of parallel connections by its structural shape, can be divided into permanent power and limit two kinds of temperature certainly by its performance.The ribbon heater is obtaining application more and more widely at industrial circle, in the insulation of the feed-line of industries such as building, iron and steel, electric power and storage tank, anti-freezing, field widespread usage such as antifreeze; Especially on the oil storage tank and long-distance transport pipes of petroleum chemical industry, the ribbon heater has clear superiority.Its weak point is: ribbon heater length depends on the length of heated object, and distance is very long sometimes, in case certain a bit breaks down, is difficult to accurate failure judgement point, if buried pipeline, difficulty is just bigger.If accurate failure judgement point just can't on-call maintenance, cause whole piece ribbon heater cisco unity malfunction, cause the medium that is transferred to solidify, bring loss to production.
Summary of the invention
The purpose of this invention is to provide a kind of optical fiber ribbon heater, to solve the problem that the very long ribbon heater of length is difficult to accurate failure judgement point.It comprises ribbon heater body 1; It also comprises optical fiber 5, inner sheath 2, screen 3 and oversheath 4; The length direction setting of said optical fiber 5 body 1 along the ribbon heater also reclines with ribbon heater body 1 mutually, on ribbon heater body 1 and optical fiber 5 outer walls, is enclosed with inner sheath 2, screen 3 and oversheath 4 from inside to outside successively.
The invention has the beneficial effects as follows: because optical fiber 5 and ribbon heater body 1 parallel the setting; In case certain a bit breaks down ribbon heater body 1; Optical fiber 5 can real-time monitor the variations in temperature at this place, and in optical cable, produces the reflection of light phenomenon, and this unusual light reflection can be delivered to the controller that is positioned at optical fiber 5 ends; Because the speed of optical signal transmission is constant in the optical cable; Therefore utilize the time of receiving reflected signal to change and just can accurately report position of failure point, be convenient to tissue maintenance rapidly, make the ribbon heater in the shortest time, recover operate as normal.In addition; Because optical fiber has powerful transfer function, and sensors of various types is installed as required, sends various signals through signal source to optical fiber; By the processor receiving feedback signals; Through Treatment Analysis, can also monitor in real time the parameters such as pressure, flow and heated object extent of corrosion that are heated in-vivo medium, carry to guarantee media security.
