The center of described inner tube is also provided with Hall current sensor, and Hall current sensor is connected with converter, and converter is connected with controller by radio transmitting device, and controller is connected with alarm;
The inwall of described inner tube is provided with and cable multiple grooves in the same way, between groove, equidistantly, is provided with steel column in groove.
Described cylindrical shell is cylindrical.
The height of described cylindrical shell is 8cm, and described cylindrical shell two ends diameter of a circle is 2.5cm.
The dismounting of slide fastener cover body easy to connect and cylindrical shell, in the time of construction, Field Force can disassemble, carry out the operation elements such as wiring, in the time not constructing, will between cover body and the upper end of cylindrical shell, be connected by zipper, prevent that the external world from contacting with cable, prevents the generation of peril.The material of cover body and inner tube is equal insulating material.Radio transmitting device comprises GPRS data transmission blocks and the GPRS data that match are with it accepted module.
The inner place, middle part of inner tube is also provided with Hall current sensor, whether Hall current sensor is charged for detection of cable, in the time having electric current to flow through, Hall current sensor will record signal and be sent to transmitter, the signal of acceptance is converted into standard signal by transmitter, and standard signal passes the signal to controller by radio transmitting device, and controller starts alarm work, relevant staff just knows that this cable is charged, can not carry out direct control or bring relevant device to carry out hot line job.
The inwall of inner tube is provided with and cable multiple grooves in the same way, and groove is provided with steel column, and the effect of steel column is to prevent that this protective sleeve, by sawed-off, has the effect of protection.
When use, the running-on place of cylindrical shell designs an embedded belt, and belt exposes 2 centimetres around edge one circle, is a cingulum on belt, pins cingulum both sides and pulls belt, and sack can be tamping.Can adapt to like this optical cable of different thicknesses.In addition, salient point is all done in inner side, edge and the belt outside of cylindrical shell, and increasing friction force, contributes to anti-skidding.
The beneficial effects of the utility model:
(1) the application, to solve practical site problems demand as object, meets daily O&M functional reliability, convenience, high efficiency demand;
(2) have practical function and industrialization design concurrently;
(3) protective sleeve adopts elastomeric material, and has slip-off preventing design, meets the different wire diameters of different websites and uses, and has stronger flexibility and versatility, after each use, substantially there is no loss, reusable, greatly saves material.

Embodiment:
Below in conjunction with accompanying drawing, the utility model is elaborated:
As Figure 2-3, a kind of protective sleeve for cable joint insulation protection, comprise the cylindrical shell 1 that adopts electronic-grade glass empire cloth to make, cylindrical shell 1 is coaxially connected with inner tube 12, the embedded belt 3 of top of described cylindrical shell 1, described belt 3 is provided with the cingulum 2 for the connection of strips two ends, and described cylindrical shell 1 inner side, edge and belt 3 outsides are provided with salient point; The top of described cylindrical shell 1 is also provided with and is hemispheric cover body 4, between cover body 4 and the upper end of cylindrical shell 1, is connected by zipper;
The inner place, middle part of described inner tube 12 is also provided with Hall current sensor 5, and Hall current sensor 5 is connected with converter 6, and converter 6 is connected with controller 8 by radio transmitting device 7, and controller 8 is connected with alarm 9;
The inwall of described inner tube 12 is provided with and cable multiple grooves 11 in the same way, between groove 11, equidistantly, is provided with steel column 10 in groove 11.
Described cylindrical shell 1 is cylindrical.
The height of described cylindrical shell 1 is 8cm, and described cylindrical shell 1 two ends diameter of a circle is 2.5cm.
In electric power construction field, from 3-50 square millimeter not etc., different shapes, because of construction needs, can be made, as line nose or integrally bending etc., as shown above in the joint needing protection to the cross-sectional area of cable.This makes blank area global shape irregular.In order there to be enough spaces, do not push front portion, protective sleeve adopts cylinder design, and according to actual cable shape of cross section and area, protection running-on diameter can be designed to 2.5 centimetres, and height is 8 centimetres, and this design neither can be little, also can not waste material.Running-on place designs an embedded belt, and belt exposes 2 centimetres around edge one circle, is a cingulum on belt, pins cingulum both sides and pulls belt, and sack can be tamping.Can adapt to like this optical cable of different thicknesses.In addition, salient point is all done in inner side, sack edge and belt outside, and increasing friction force, contributes to anti-skidding.
Material aspect, insulation is overriding concern, therefore adopts electronic-grade glass empire cloth, it is good that it has electrical insulation capability, fire protection flame retarding, waterproof, ageing-resistant, weatherability, high strength, high-modulus, the feature such as price is suitable, light.
As shown in Fig. 1 (a)-Fig. 1 (c), in practice of construction, a lot of situations need to arrange that power line is to power supply panel cabinet to communication equipment, and power supply panel cabinet has a lot of roads air switch, has part copper cash outside exposed after each road connects.With the cable joint of line nose, the cable joint of integrally bending, common cable joint, if do not note when line, certain root in zero line, live wire, ground wire will touch other pipeline connectors and cause short circuit, understands like this damage equipment, causes casualties, when wiring, the bare wire exposing is used this interface sleeve bag to play tight bundle, convenient, fast, safety.Stop temporarily not have fixing the end of a thread to contact with other band point positions with this.
Home and abroad research institution and unit are less in the design application aspect for Protectivre sleeve for cable splice at present.This project reaches after re-set target, possesses practical value, can directly apply to on-the-spot O&M work, nets other net province companies in power system operation service work for state, particularly carry out cable associative operation aspect have application value.
Determine after protective sleeve material type selecting and appearance design preliminary, contact specialized factory customization test version, and choose experiment cable and test.Draw comparative analysis report according to test result, protective sleeve carried out to later stage optimization, can reach that insulation is good, wrapping firmly, the actual working environment requirement such as easy accessibility, applicability be strong.
