Description

The livewire work slide
Technical field
The utility model relates to the instrument of a kind of power construction field use, refers in particular to a kind of livewire work ladder.
Background technology
At present, the electric load demand continues to increase substantially, and the user has proposed requirements at the higher level to quality, power off time, number of times and the reliability etc. of electric power, launch the charging construction operation, reduce power failure range and power off time, guarantee to satisfy the user to the demand of electric power, become the demand for development of field of power transmission.
Livewire work refers to a kind of operational method of not having a power failure and overhauling, test on the high-tension electricity construction equipment.Livewire work can be divided three classes according to the relation between human body and electrical body: equipotential live line work, earth potential working and medial potential working.Wherein, equipotential live line work is that the operating personnel passes through electrical connection, makes the current potential of own health rise to charged position current potential, and isolates and directly live part carried out operation with different potentials is suitable on every side.At present, when carrying out equipotential live line work on 110kV and Above Transmission Lines shaft tower, adopt insulating ladder or insulated flexible ladder mode to enter operation field, ladder two ends are connected with the steel tower cross-arm with wire respectively more, and the operating personnel stands in operation on insulating ladder or insulated flexible ladder; But due to the impact of the factors such as tower, wire and cross-arm relative position, still there is following potential safety hazard in this dual mode:
1) safe distance is not enough, for example: the 110kV cat-head transmission tower, wherein phase conductor is apart from tower body 1918mm, the limit phase conductor also only has 2000mm apart from tower body, operating personnel on insulating ladder itself is again with short circuit 600mm, operating personnel short circuit 300mm more also in moving process, stipulate " when electric pressure is 110kV according to livewire work in " State Grid Corporation of China's electric power safety working regulation " (power circuit part), the livewire work minimum safe distance must not be less than 1000mm, the minimum combination gap must not be less than 1200mm ", obviously, when carrying out livewire work on this tower, if according to the routine work method, to be difficult to guarantee normally carrying out of livewire work,
2) return to difficulty large, for example: on anchor support, because insulator string is sagging, it is larger that insulating ladder sets up the rear gradient, and after the upper ladder of operating personnel, the flat terraced gradient even can surpass 30 degree, cause operating personnel to return to after hours difficulty larger;
3) insulating ladder shaft tower side is fixedly connected with cross-arm, and its installation is had relatively high expectations to cross-arm shape, angle;
4) safety factor is poor, and due to terraced body smoother, stability is bad, and the inconvenience of operation erect-position brings certain impact for high-altitude working safety.
Publication number is the patent of invention of CN 102383719A, a kind of insulation sliding board of using for the power transmission lines overhauling operation is disclosed, comprise terraced body, sliding seat and slide hook, the ladder body is the main body of carrying, sliding seat is installed in ladder with it and can slides along terraced body, be provided with the locking member that can coordinate with terraced body locking on sliding seat, the slide hook is arranged on terraced body front end, and the slide hook is used for terraced body is hung at wire.Although can overcome above-mentioned part shortcoming, but because insulation sliding board adopts suspending way, and adopt flexible snap close (as rope) to be fixedly connected with being connected of shaft tower end, therefore the situation of horizontal hunting easily appears in insulation sliding board, has certain danger, and the cross-arm setting position is had certain requirement, and also there is wear problem in the rope connection in addition, and certain insecurity is arranged.
