Description
Technical field
The invention belongs to technical field of power systems, and in particular to the insulation masking that a kind of 10kV insulating bars working system uses
Instrument and its installation and the method for removing insulated shielding cover.
Background technology
10kV distribution uninterrupted operation modes have insulating bar working system, insulating glove working system and comprehensive uninterrupted operation
Method, currently used is to use insulating glove method livewire work using aerial lift device with insulated arm.It is past due to being influenceed by terrain environment etc.
Toward some line insulation bucket arm vehicles can not just complete livewire work work, into it is a wide range of implementation livewire work " bottleneck ",
Particularly run into load weight, the circuit more than Electricity customers, that can only be just " standing by anxiously ".In order to further service Electricity customers,
Improve service quality, Guo Wang companies actively promote new livewire work technology, to fill up livewire work " short slab ".Insulating bar operation
Method is exactly one of which important means.The events in operation are using special isolation bar, special mask, by the close of operating personnel
Cut distribution closes, and on the premise of being perfectly safe, the work such as main traverse line linear diameter measurement, stripping insulation layer, drainage connection is completed, so as to real
In the environment of aerial lift device with insulated arm can not being used now, livewire work can be still completed.
Insulating bar working system has advantages below compared to insulating glove working system：1. operating environment requires lower, using more
Extensively, it can both be operated in bucket arm vehicle, on insulated platform, can be stepped on bar again and be operated；2. operation when human body with it is powered
Physical efficiency keeps safety work distance, less exposure risk, avoids the generation of personal injury；3. the fault rate of insulating rod-like tools
Lower, same instrument goes for more voltage class, can be in narrower spatial operation, than insulating glove method more
Safety.4. the service life of insulating rod-like tools is longer, detection cycle is longer, and general insulating rod-like tools are than insulating glove class work
Tool needs less detection 1:4, so, insulating bar working system is carried out energetically by Guo Wang companies in recent years.But at present in distribution absolutely
The insulation shading tool of edge bar working system is less, and most of is all that not only price is high from imported from America, and heavy, installation
Dismounting is wasted time and energy, and carries out insulating bar operation using Imported Insulation shading tool, the installation and disassembling section of mask can consume
It is substantial amounts of physical (50%) to fall operating personnel, (midway is needed so as to cause whole hotline maintenance work not smoothly complete disposably
Interruption rest or replacement operation personnel), waste time and energy, efficiency is low.In summary, it is necessary to in 10kV insulating bar working systems
The difficult point of insulation masking is tackled key problems, and development of new insulation masking Work tool, to adapt to the requirement of new model, effectively lifts operation
Security and efficiency.
