Abstract

An insulating ladder for electric operations of grounding wire or optical fiber composite aerial wire comprises an insulating ladder bracket, an insulating ladder head, a sliding groove hanging inserting opening positioned on the upper part of the guard bars of the two sides of the insulating ladder. The sliding groove inserting opening is screwed with and provided with a plurality of in-line roller wheels hanged and sliding on the aerial wire. The insulating ladder for electric operations changes the previous method which takes a single roller wheel as the force manner of the force point of the ladder to a multi-point uniformly-arranged force manner of a plurality of metal roller wheels, thus changing the previous two-point bearing of the high voltage stress acting on the aerial wire to a multi-point uniformly-arranged, reducing the pressure of the OPGW optical fiber composite aerial wire, avoiding the damage and breaking of optical fiber, and improving the operational safety of the electric operations of the grounding wire or optical fiber composite aerial wire and maintenance efficiency. Besides, the insulating ladder of the utility model is used conveniently and operates stably, thus reducing the hardness of the detection of the operators.

Description

The charged processing operation insulated flexible ladder of lead wire and earth wire and Optical Fiber Composite type overhead wire
Technical field
The utility model relates to a kind of overhead wire live line working device, and in particular, the utility model relates to the charged processing operation insulated flexible ladder of a kind of lead wire and earth wire and Optical Fiber Composite type overhead wire.
Background technology
In service in the high pressure that spreads all over domestic vast both urban and rural area and ehv power transmission engineering and power transmission and transformation thereof, must use the 220-500 kilovolt transmission line of long distance, be to guarantee power transmission and transformation security of operation, reliable, every year will to the leading of described high pressure and ehv power transmission circuit, line defect and foreign matter carry out considerable charged work of treatment.
In the past, as traditional to the leading of described high pressure and ehv power transmission circuit, line defect and foreign matter carry out considerable charged processing operation method, have:
Charged processing overhead ground wire defective and foreign matter.That is, on ground wire, hang " insulated flexible ladder " formed by the steel roller ladder head and the insulation rope ladder of overhead ground wire special use.The operating personnel climbs up insulated flexible ladder from the head of mast, outwards slides onto the setting that defective or foreign matter are handled along overhead ground wire, adds to tie up or remove the foreign matter operation.
Charged processing lead defective and foreign matter.Promptly, on shaft tower, the earth potential working hand will be hung rope ladder with insulating bar and be lifted on the lead with chain wheel rope, the operation hand is dilatory to defective or the pending point of foreign matter along lead with this insulating block rope on the ground, will be rolled light ladder head by the aluminium of lead special use with this chain wheel rope again and hang on lead with " insulated flexible ladder " that the insulation rope ladder is formed.Then, climb insulated flexible ladder to the lead equipotential, add and tie up or remove the foreign matter operation by the equal potential working hand of wearing a complete set of screening clothing.
Charged processing to foreign matters such as kite string or plastic film tapes.The general employing of this processing hangs special-purpose duplex insulating block rope at overhead ground wire one L, and this chain wheel rope is connected for insulation rope two ends and buckles the no string for binding a plait that a metal colludes.Then, by the Ground Operation hand that duplex insulating block rope is dilatory to defective or the pending point of foreign matter along overhead ground wire, the no string for binding a plait of tractive insulation up and down uses the metal on this rope to collude the excision foreign matter again.
The problem that said method exists is:
1) the present overhead ground wire on the extra high voltage network, more employing OPGW Optical Fiber Composite type overhead wire, as adopt traditional operational method and operating apparatus, can make optical fiber in the OPGW Optical Fiber Composite type aerial construction impaired, fracture.
This be because:
Traditional insulated flexible ladder ladder head makes the operating personnel be displaced to setting from the shaft tower top along line by two roller skids along the line.In working order down, act on press packet on the overhead ground wire by the rope ladder head roller and contain instrument weight, equal potential working hand body weight and Ground Operation hand such as insulated flexible ladder and put on pulling force on the insulated flexible ladder, estimate that total amount can reach more than the 1600N.And overhead ground wire is again the linear chain state that is tensioning, when being subjected on the rope ladder head must producing bending behind two (roller) point pressure, cause optical fiber in the OPGW Optical Fiber Composite type aerial construction impaired, fracture.
2) at present big span line adopts bundle conductor more, and the 500KV circuit is conductors on quad bundled, installs conductor spacer in the line shelves.Therefore, can not adopt to hang on solid conductor not have insulated flexible ladder, the operation hand slides onto the method for setting charged processing lead defective and foreign matter along line.
3) along with the urban construction development, extra high voltage network scissors crossing thing along the line gets more and more.Therefore, adopt to hang insulated flexible ladder on lead wire and earth wire, the suitable line of operation hand slides onto the method for setting charged processing lead defective and foreign matter, is subject to cross over thing and stops.
In addition, all there is operating personnel's the big problem of detection operation intensity in said method.
Through to the traditional operational method of charged processing lead defective and foreign matter and the present situation investigation and analysis of tool using, the utility model designer finds:
The insulated flexible ladder ladder head that charged processing OPCW Optical Fiber Composite type overhead wire defective and foreign matter are used, change in the past with the force way of single roller as the rope ladder stress point, but the imagination development and design be provided with a plurality of, can regulate the metal roller of stress voluntarily, thus, can make the 1600N compression that acts on the overhead ground wire concentrate carrying by original 2, become multi-point equispaced, thereby, significantly reduce OPGW Optical Fiber Composite type overhead wire pressure, avoid optical fiber impaired, fracture.
Thus, can be when the charged processing of lead wire and earth wire and Optical Fiber Composite type overhead wire be operated.Significantly reduce OPGW Optical Fiber Composite type overhead wire pressure, avoid optical fiber impaired, fracture, simultaneously, improve the charged processing processing safety and the maintaining efficient thereof of lead wire and earth wire and Optical Fiber Composite type overhead wire, alleviate operating personnel's detection operation intensity.
