Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of novel intelligent high temperature discoloration early warning fireproof cable.
Background technology
2010, be informed of a case fire 13.17 ten thousand altogether in the whole nation, dead 1108 people, injured 573 people, direct property loss 17.7 hundred million yuan.Wherein, because of the fire totally 40481 that electrically reason causes such as wire short-circuiting, overload and electrical equipment malfunction, accounting for the 30.7% of fire sum, fire and life security incident that electricity consumption causes make people startling.The fire general aspects caused with electrification is more severe, and difficulty of suing and labouring is relatively big, and the time that effectively processes is shorter.And conventional electric induction type detector only just can be reported to the police when fire or after occurring with electrification and reach to a certain degree, it is impossible to the usable condition of cable is given warning in advance.Fundamentally can't resolve source problem.
The most traditional detection cable fault typically uses electric induction type detector and built-in temperature-sensitive insulating twisted core type cable for automatic alarm and to prevent the dangerous situations such as fire, and these two kinds of devices and product all have the disadvantage that
1) electric induction type detector purchase cost in whole construction is higher, and maintenance cost is higher, and maintenance time promptness is inadequate.
2) electric induction type detector can only just can be with induction alarm when accident occurs and causes certain consequence, it is impossible to play the effect occurred of preventing accident.
3) electronic induction detector property fastidious to construction environment relies on relatively big, and sealing is poor.Internal structure on-the-spot after construction is uncertain, and electronic induction detector is easily subject to electromagnetism, dust, and the impact of mosquito can cause dangerous situation do not report or report by mistake, has a strong impact on its normal productive life.
4) built-in temperature-sensitive insulating twisted core formula cable cost relatively high technology is complicated, easily there is no actually used value and temperature detection effect due to what the partial destruction of some parts in cable caused this cable.
5) owing to built-in steel wire has a strong impact on the bending radius of cable and lays difficulty in the actual laying of built-in temperature-sensitive insulating twisted core formula cable.
6) built-in temperature-sensitive insulating twisted core formula cable due to pair twist core be steel wire, intensity is higher, brings certain difficulty to stablizing of pair twist structure, easily originates from stress and steel wire mechanics tired, have a strong impact on the actual production of cable in stranding process.
It is the most backward that the present invention can solve current cable community cable product, the most intelligentized problem, it is therefore an objective to a kind of fire prevention, waterproof, nontoxic, environmental protection, security will be provided high, non-toxic and non-pollution green safety intelligence high temperature discoloration early warning fireproof cable.
