Description
Technical field
The present invention relates to a kind of heat shield and the method for carrying out heat-resisting wire live line working thereof.
Background technology
Heat-resisting wire has the large feature of through-current capability, and being applied to overhead transmission line can significantly improve its transmission capacity.The maximum operating temperature of the heat-resisting wire that current China transmission line uses can reach 240 degrees Celsius.
When adopting the transmission line of heat-resisting wire to occur the defects such as insulator breakage, wire wearing and tearing, because circuit transmission capacity is larger, generally do not allow to carry out interruption maintenance operation, therefore, the safe and stable operation of live line working to the transmission line ensureing heat-resisting wire seems particularly important.
For the transmission line of conventional wires, the maximum operating temperature of wire is no more than 70 degrees Celsius, during live line working, and operating personnel is without the need to considering heat insulation protection.And for the transmission line of heat-resisting wire, the maximum operating temperature of wire to 240 degrees Celsius, can need to adopt heat insulation protection, is subject to temperatures involved to prevent operating personnel.
Summary of the invention
The object of this invention is to provide a kind of heat shield, during live line working for the transmission line of heat-resisting wire, heat insulation protection is carried out to operating personnel, prevent operating personnel to be subject to the impact of high temperature.
For solving the problem, the technical solution used in the present invention is:
A kind of heat shield, comprise cross section for the heat shield main body of " U " shape and the hook being arranged on a pair " U " shape on the inwall of heat shield main body two ends, described hook lower end connects insulated handle.Heat shield forms effective isolation between high temperature wire and operating personnel, avoids operating personnel directly to contact with high temperature wire, prevents high temperature wire from damaging operating personnel.
As a further improvement on the present invention, described hook is connected by connecting rod with insulated handle.The screening clothing that connecting rod and operating personnel dress is connected by potential transfer line, makes operating personnel and wire keep equipotential, prevents potential difference damaging human body.
As a further improvement on the present invention, described connecting rod is provided with binding post.Arrange the connection that binding post facilitates potential transfer line and connecting rod, operability is stronger.
Further improve as of the present invention, described hook is arranged in heat shield main body by bolt.Bolted mode is convenient to the parts dismantling and change heat shield, and connective stability is good, and security performance is higher.
Another object of the present invention is to provide a kind of method adopting heat shield to carry out heat-resisting wire live line working, and the method is simple, more conveniently can carry out live line working when heat-resisting wire temperatures as high 240 degrees Celsius to it.
The present invention adopts heat shield to carry out the method for heat-resisting wire live line working, comprises the steps:
1) operating personnel dresses screening clothing;
2) screening clothing and heat shield is connected with potential transfer line;
3) operating personnel passes through insulation delivery vehicle close to heat-resisting wire;
4) heat shield is placed on heat-resisting wire, makes human body and heat-resisting wire form equipotential;
5), after potential transfer, operating personnel leans on heat shield and carries out live line working.
It is few and easily implement that the present invention adopts heat shield to carry out the utilization step of the method for heat-resisting wire live line working, and operating personnel can not be used in learning performance program and cost a lot of money the time.
As further improvement, operating personnel when operation and heat-resisting wire keep the distance of more than 10 centimetres.Operating personnel and wire keep the distance being no less than 10 centimetres, and fail safe is better.
In sum, the invention has the beneficial effects as follows: when the live line working of transmission line heat-resisting wire, heat insulation protection is carried out to operating personnel, operating personnel is prevented to be subject to the impact of high temperature, keep operating personnel equal with the current potential between high temperature wire, potential difference is zero therebetween, can not damage human body, structure of the present invention is simple simultaneously, and security performance is good.It is simple to operate that the present invention adopts heat shield to carry out the method for heat-resisting wire live line working, saves the time of learning performance program.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Heat shield as depicted in figs. 1 and 2, comprise heat shield main body 1 that cross section is " U " shape and be fixedly installed on the hook 2 of a pair " U " shape on the inwall of heat shield main body 1 two ends for a pair respectively by bolt 6, described hook 2 lower end connects insulated handle 4 by connecting rod 3, and described connecting rod 3 is provided with binding post 5.
When live line working personnel need to carry out equal potential working on the 220kV transmission line heat-resisting wire 7 that temperature is higher, operating personnel dresses a complete set of screening clothing and carries heat shield, and screening clothing is connected by potential transfer line with the binding post 5 of heat shield.Operating personnel passes through insulation delivery vehicle close to high temperature wire.
As shown in Figure 3 and Figure 4 when using heat shield, wear the operating personnel of a complete set of screening clothing clothes at distance heat-resisting wire 7 about 20 ~ 30cm place, heat shield is placed on heat-resisting wire 7 by the insulated handle 4 of hand-held heat shield, the binding post 5 of heat shield is connected with operating personnel's screening clothing with it by potential transfer line, human body and heat-resisting wire 7 is made to form equipotential, namely potential difference is zero between the two, and also namely voltage is zero, thus avoids the injury that high voltage causes operating personnel.
After potential transfer, can directly rely on heat shield during equal potential working personnel operation, now operating personnel and heat-resisting wire 7 keep the distance of more than 10 centimetres substantially.Now, between operating personnel and heat-resisting wire 7, there is the heat insulation object such as air and heat shield, operating personnel can be made not by the impact of high temperature.The screening glove that operating personnel dresses has short time heat insulation ability, operating personnel discontinuous contact heat-resisting wire 7 and neighbouring high temperature gold utensil thereof can carry out operation, or adopts the hand tools such as spanner indirectly to carry out operation to heat-resisting wire 7 and neighbouring high temperature gold utensil thereof.
Described in the present invention, concrete case study on implementation is only better case study on implementation of the present invention, is not used for limiting practical range of the present invention.Namely all equivalences done according to the content of the present patent application the scope of the claims change and modify, all should as technology category of the present invention.
