Abstract
The utility model discloses a composite mine cable for temperature measurement. The composite mine cable comprises a power wire core, a ground wire core and a temperature measurement cable. The power wire core and the ground wire core intertwist into a cable. The temperature measurement cable comprises elastic steel wires, temperature-sensitive insulating material, a wrapping tape, a braided shield and a sheath from inside to outside. The temperature measurement cable winds the cable intertwisted through the power wire core and the ground wire core in a sine wave manner, and is coated by an oxygen isolation tape. The sheath coats the wrapping tape. The composite mine cable for temperature measurement can satisfy the power supply requirement of a mine, and measure and control the temperature of the cable. Thus, the safe operation case is monitored, and the early warning effect is achieved.
Description
technical field
the utility model relates to a kind of cable, particularly a kind of compound thermometric mine cable.
background technology
china's coal-mine disaster is heavier, and gas, water, fire are the main inducing of China's coal-mine disaster.In China's State owned coal mine, the disaster that high biogas (gas) and coal and gas cause is outstanding, account for 47% of mine disaster total number of accident, the mine with potential coal dust explosion hazard accounts for 86% of mine sum, exist the mine of spontaneous fire tendency to account for 55% of mine sum, and rock pressure [in mine is large, flood is serious.In state-owned local mine, 38% belongs to high gassy mine, and 42% has quick-fried dust explosion danger, and 29% exists spontaneous fire tendency.Due to coal production environment and inclement condition, be subject to the threats of water, fire, gas, coal dust, ore deposit pressure five large harm, add that the many electrical equipments in down-hole are often in mobile status, installation and maintenance condition is also far away from ground, its fault and the accident rate equipment that is above the ground level far away.In coal mining accident, having accounted for of being caused by electrical equipment is nearly more than 50%, and wherein mine fire accident more than 70% is caused by electric, and gas and dust explosion accident more than 60% are caused by explosive.Wherein, because causing fire, gas explosion accident etc. that insulation breakdown causes, electric cable heating also happens occasionally.Compound thermometric mine cable is exactly that the cable in using is carried out to thermometric, monitoring constantly, and the accident such as cable breakdown, fire is played to forewarning function, thereby reduces or avoid the generation of accident.
traditional mine cable self does not have temp measuring system, need to lay in addition cable for measuring temperature and carry out thermometric.When cable for measuring temperature installation, need open power cable crane span structure upper cover plate, cable for measuring temperature is attached in power cable crane span structure, cable for measuring temperature seals cable testing bridge upper cover plate more again after setting up.Such colliery just needs buying mine cable and cable for measuring temperature separately, and lays respectively.Meanwhile, because making cable for measuring temperature and mine cable, this system of laying has certain clearance, the temperature that cable for measuring temperature just can not Measurement accuracy mine cable like this.
utility model content
the drawback existing for above-mentioned conventional art, the technical solution adopted in the utility model is: a kind of compound thermometric mine cable, comprise power core, core, cable for measuring temperature, described power core and ground core twisted synthesizing cable; Described cable for measuring temperature comprises elastic wire, temperature-sensitive insulating material, band, braid shielded and sheath from inside to outside, and this cable for measuring temperature is wound in sinusoidal wave mode on the cable of power core and ground core twisted synthesizing cable, and coated with oxygen barrier band, band is coated with sheath.
further, described cable for measuring temperature is wound in outside cable core in sinusoidal wave mode, and wave peak length is not more than 850cm.
further, described sheath is fire-retardant or low smoke halogen-free.
the utility model is according to the characteristic of mine cable and cable for measuring temperature, to two kinds of product mix designs, thereby produces a kind of composite cable.When any temperature rise of a certain position of its protection or certain is during to the rated function temperature of heat-sensitive cable, between two steel wires, state of insulation changes, and produces alerting signal; The utility model advantage is as follows:
1, engineering cost is cheap, easy for installation flexibly, can directly and protect object contact, and its guard space is long, scope is wide;
2, this cable for measuring temperature alarm distance time suitable, operating temperature is reliable and stable;
3, can play the effect of protection cable total length.Cable for measuring temperature lays along power cable total length, all can gather the temperature of power cable in length range, does not omit a little, also may detect even extraneous factor changes cable temperature.
, temperature sensing is sensitive, for the prevention of fire, put out the valuable time of having striven for.Because cable for measuring temperature is sinusoidal wave contact design, what the temperature variation of power cable can be very fast is arrived by thermometric cable detection.
, owing to being compound thermometric mine cable, can once construct, reduced purchase cost, reduce executive cost.
therefore, compound thermometric mine cable can meet mine power supply needs, measurement and control cable temperature in time again, thus the safe operation situation of monitoring cable plays the effect of safe early warning.
accompanying drawing explanation
fig. 1 is the utility model structural representation;
fig. 2 is that schematic diagram is put in the utility model cable for measuring temperature office;
in its figure: 1-sheath 1; 2-oxygen barrier band; 3-cable for measuring temperature; 4-para tape; 5-conductor; 6-filling material; 7-works out shielding; 8-elastic wire; 9-heat-sensitive cable; 10-band 2; 11-sheath 2.
embodiment
the utility model illustrates specific implementation method using Fig. 1 as most preferred embodiment.As shown in Figure 1, this compound thermometric mine cable, comprise power core, core, cable for measuring temperature 3, power core and ground core twisted synthesizing cable; Cable for measuring temperature 3 comprises elastic wire 8, heat-sensitive cable 9, band 10, braid shielded 7 and sheath 11 from inside to outside, and this cable for measuring temperature 3 is wound in sinusoidal wave mode on the cable of power core and ground core twisted synthesizing cable, and coated with oxygen barrier band 2, oxygen barrier band 2 is coated with sheath 1.Cable for measuring temperature 3 is wound in outside cable core in sinusoidal wave mode, and wave peak length is not more than 850cm.
cable for measuring temperature 3 lays along power cable total length, all can gather the temperature of power cable in length range.When any temperature rise of a certain position of its protection or certain is during to the rated function temperature of heat-sensitive cable 9, between two steel wires, state of insulation changes, and produces alerting signal.Because cable for measuring temperature 3 is the designs of sinusoidal wave contact, the temperature variation of power cable can be detected by cable for measuring temperature 3 very soon, and temperature sensing is sensitive, can be fire prevention, put out and strive for the quality time.Sheath 11 adopts fire-retardant or low smoke halogen-free, poisonous gas generation can effectively reduce cable fire time, and there is low-smoke and anti-flammability.
the foregoing is only a preferred embodiment of the present utility model; can not limit protection domain of the present utility model with it; the utility model also can have other structural change; as long as the equalization of doing according to protection domain of the present utility model changes and modifies, all should belong in the scope that the utility model contains.
