Abstract
The invention relates to an insulated single-core constantan alloy stranded wire PFA (soluble Polytetrafluoroethylene) jacket short-distance constant power electric heating tape which is mainly used for the heat insulating and the heating of pipelines and containers of petrochemical industry, fire fighting, steel, electric power, and the like. The electric heating tape sequentially comprises a core wire (1), a first insulating layer (2), a second insulating layer (3), an inner jacket (4), a shielding layer (5) and an outer jacket (6) which are compounded from inside to outside, wherein a single-core constantan alloy stranded wire is used as the single-core the core wire (1); and the first insulating layer (2), the second insulating layer (3), the inner jacket (4) and the outer jacket (6) are made of a tetrafluoroethylene-perfluoroether copolymer. During mounting, the electric heating tape can be repeatedly bent, thereby the service life is greatly prolonged.
Description
(1) technical field
The present invention relates to a kind of permanent power ribbon heater.Be mainly used in the insulation and the heating of pipelines such as petrochemical industry, fire-fighting, iron and steel, electric power, container.The ground that also is applicable to solar pipe, the civil buildings snow melt etc. of warming up.Belong to the electrothermal device technical field.
(2) background technology
Before the present invention made, conventional permanent power ribbon heater was a kind of permanent power ribbon heater in parallel.Its structure as depicted in figs. 1 and 2.Its operation principle: power source bus is two parallel insulated copper wires, twines heating wire on the inner sheath insulating barrier, and heating wire is connected with power source bus at a certain distance, forms continuous parallel resistance.After the power source bus energising, each parallel resistance heating, thereby form a continuous heating tape.Its characteristics: the caloric value of ribbon heater unit length is constant, and the ribbon heater of use is long more, and the power of output is big more.The application scenario: permanent power ribbon heater in parallel generally is used for the tracing thermal-insulating of little pipeline or pipe network system short tube line.This perseverance power ribbon heater in parallel existing problems: permanent power ribbon heater in parallel is to be welded on copper busbar as heater by the thinner nichrome wire in line footpath because of product, should not repeat bending when install the ribbon heater, and useful life is short partially.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, can repeat bending when providing a kind of ribbon heater to install, the single core constantan twisted wire PFA insulation that useful life is long and the permanent power series electrical of the sheath short distance torrid zone.
The object of the present invention is achieved like this: a kind of single core constantan twisted wire PFA insulation and the permanent power of sheath short distance ribbon heater, it is characterized in that described ribbon heater from interior from outside successively by heart yearn, first insulating barrier, second insulating barrier, inner sheath, screen and oversheath totally six layers be composited, described heart yearn adopts single core constantan twisted wire, and first insulating barrier, second insulating barrier, inner sheath and jacket material adopt tetrafluoroethene-perfluor ether copolymer.
Operation principle:
PFA insulation of the single core constantan of the present invention twisted wire and the permanent power of sheath short distance ribbon heater are a kind of electric-heating belts of being made heater (heart yearn), the insulation of PFA (tetrafluoroethene-perfluor ether copolymer) do and sheath by the constantan twisted wire, heart yearn two ends, ribbon heater are inserted power supply phase line and zero line respectively, form a single-phase heating circuit.Because the resistance of heart yearn unit length and the electric current that passes through are all constant, so whole ribbon heater generates heat evenly from beginning to end, power output is constant.
The invention has the beneficial effects as follows:
Single core constantan twisted wire PFA insulation has power output and the temperature resistant grade identical with permanent power ribbon heater in parallel with the permanent power of sheath short distance ribbon heater, but, mode of heating generates heat because of being become by heart yearn by the electrothermal wire heating, avoided ribbon heater in parallel in the past owing to bend repeatedly and the aging fault that causes of pad, can repeat bending when install the ribbon heater, prolong useful life greatly.200 ℃ of the high-temperature resistants of PFA insulating barrier and sheath ribbon heater product, 120 ℃ of the high maintenance temperature of medium.

(5) embodiment
Referring to Fig. 3~4, Fig. 3 is PFA insulation of the single core constantan of the present invention twisted wire and the permanent power of sheath short distance ribbon heater Facad structure schematic diagram.Fig. 4 is the B-B cut-away view of Fig. 3.By Fig. 3 and Fig. 4 as can be seen, PFA insulation of the single core constantan of the present invention twisted wire and the permanent power of sheath short distance ribbon heater, from interior outside oneself successively by heart yearn 1, first insulating barrier 2, second insulating barrier 3, inner sheath 4, screen 5 and oversheath 6 totally six layers be composited.Described heart yearn 1 adopts single core constantan twisted wire; First insulating barrier 2, second insulating barrier 3, inner sheath 4 and oversheath 6 materials adopt PFA (tetrafluoroethene-perfluor ether copolymer).
Claims (1)
1. a single core constantan twisted wire PFA insulate and the permanent power of sheath short distance ribbon heater, it is characterized in that described ribbon heater from interior from outside successively by heart yearn (1), first insulating barrier (2), second insulating barrier (3), inner sheath (4), screen (5) and oversheath (6) totally six layers be composited, described heart yearn (1) adopts single core constantan twisted wire, and first insulating barrier (2), second insulating barrier (3), inner sheath (4) and oversheath (6) material adopt tetrafluoroethene-perfluor ether copolymer.
