Description
Technical field
The utility model relates to the power transmission field, particularly a kind of power cable.
Background technology
In a lot of places of field of oil drilling, such as top-drive drilling, automatically controlled room etc., owing to be mixed with the certain density gas that explosion hazard is arranged in the air, these places are called as the hazardous area.Electric equipment in that install in these zones must satisfy the standard code of GB3836-2000 " explosive gas atmosphere electrical installation ", could guarantee the fail safe of using.
But employed common power cable complete set of equipments is easy to generate spark at cable with the joint that electrical source of power or drilling rig are connected at present, blasts easily in the place with explosion risk gas, and production security is caused very big threat.
In addition, the work-yard condition of field of oil drilling all compares badly, and the sheath of employed common power cable complete set of equipments does not possess good pliability, tensile strength, grease resistance at present, do not meet GB3836-2000 about explosion-proof regulation yet, therefore can not use in the place that has explosion risk gas to exist.
The utility model content
The utility model provides a kind of power cable, has tensile strength height, sheath that pliability is good, can use in the place with explosion risk gas.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of power cable, its key are, comprise cable body, be connected the waterproof anti-explosion cable connecting arrangement at cable body two ends and be set in the outer tension sheath of cable body;
Fill casting glue between described cable body and the tension sheath.
Preferably, described power cable comprises N cable body and 2N waterproof anti-explosion cable connecting arrangement, and the two ends of each cable body are connected with a waterproof anti-explosion cable connecting arrangement respectively;
A described N cable body is set in the tension sheath.
Preferably, described power cable also comprises two fixed flanges and two metal transfer pipes,
Described fixed flange and metal transfer pipe are by being threaded;
Described two metal transfer pipes are connected by the two ends of casting glue with described tension sheath respectively;
The two ends of described cable body pass from the centre bore of described fixed flange respectively.
Preferably, described cable body comprises three core power cables.
Preferably, described cable body also comprises three core ground wire cables or a core ground wire cable.
By above technical scheme as can be known, power cable of the present utility model is when work, the one end is connected with electrical source of power, one end and Power Drive Unit are (for example: top-drive drilling) be connected, the waterproof anti-explosion cable connecting arrangement self that plays interconnect function can form an independently explosion-proof cavity, even inside produces spark or blasts and also can not arrive outside by propagation of explosion.The power connection is sulfided into integral body with cable body and tension sheath by casting glue, makes cable have good resistance to wear, tensile strength, grease resistance in the process of using.Simultaneously the utility model fixes by fixed flange and top-drive drilling, thereby realizes the effect that its power transmits fixedly the time.
Description of drawings
Fig. 1 is the structural representation of power cable of the present utility model.
Embodiment
The purpose of this utility model is to provide a kind of power cable, has tensile strength height, sheath that pliability is good, can use in the place with explosion risk gas.
For making the purpose of this utility model, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
Fig. 1 is the structural representation of power cable of the present utility model.As shown in Figure 1, power cable of the present utility model comprises cable body 2, is connected the waterproof anti-explosion cable connecting arrangement 1 at cable body 2 two ends and is set in cable body 2 tension sheath 6 in addition.
Wherein, fill casting glue 5 between cable body 2 and the tension sheath 6, so that form one between cable body 2 and the tension sheath 6.
The employed waterproof anti-explosion cable connecting arrangement 1 of power cable of the present utility model be used for electrical source of power or Power Drive Unit (for example: top-drive drilling) be connected, himself can form an independently explosion-proof cavity, even when producing spark even blasting in this jockey 1 inside, can not arrive outside by propagation of explosion yet, thereby eliminated production safety hidden danger, be particularly suitable for using in place with explosion risk gas.
Preferably, as shown in Figure 1, according to different Power Drive Units, power cable can have a plurality of cable bodies.That is, power cable of the present utility model comprises N cable body 2 and 2N waterproof anti-explosion cable connecting arrangement 1.Wherein, the end of each cable body 2 is connected with a waterproof anti-explosion cable connecting arrangement 1 respectively.This N cable body 2 all is set in the same tension sheath 6.
Preferably, cable body 2 of the present utility model comprises three core power cables and three core ground wire cables.Perhaps, according to different application apparatuss, cable body 2 also can comprise three core power cables and a core ground wire cable.But cable body of the present utility model is not limited in this, can adopt multi-form cable according to different application requirements.
Further, power cable of the present utility model also comprises two fixed flanges 3 and two metal transfer pipes 4, between fixed flange 3 and the metal transfer pipe 4 by being threaded.Two metal transfer pipes 4 are connected with the two ends of tension sheath 6 by casting glue 5 respectively.
Wherein, the length of cable body 2 should be greater than the length of tension sheath 6.That is, the two ends of cable body 2 pass from the centre bore of fixed flange 3 respectively, are connected with waterproof anti-explosion cable connecting arrangement 1 respectively then.
Fixed flange 3 is used for power cable is fixed in Power Drive Unit, and it is formed into one by metal transfer pipe 4 and casting glue 5 with tension sheath 6.Simultaneously, fixed flange 3 by tension sheath 6 two ends with casting glue 5 sealings, tension sheath 6 can also be formed the space of a sealing, thereby further avoid outside hazardous gas, greasy dirt etc. to enter tension sheath 6 inside, cause burn into to damage cable body 2.
Power cable of the present utility model is when work, the one end is connected with electrical source of power, one end and Power Drive Unit are (for example: top-drive drilling) be connected, the waterproof anti-explosion cable connecting arrangement self that plays interconnect function can form an independently explosion-proof cavity, even inside produces spark or blasts and also can not arrive outside by propagation of explosion.The power connection forms integral body with cable body and tension sheath by casting glue, makes cable have good resistance to wear, tensile strength, grease resistance in the process of using.Simultaneously the utility model fixes by fixed flange and top-drive drilling, thereby realizes the effect that its power transmits fixedly the time.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
