Description
Technical field
The special isolation shading tool of switch is isolated in being replaced the present invention relates to a kind of insulating bar method on-load, extensively should
It is isolated in being replaced for overhead distribution insulating bar method on-load in the work of switch, belongs to distribution line hotline maintenance and show
Field technology field.
Background technology
Disconnecting switch is common a kind of switchgear without arc-control device on distribution overhead line, is had in separating brake bright
Aobvious cut-off point, to ensure the safety inspection of other electrical equipments；Normal duty electric current can reliably be passed through in "on" position
And short-circuit current.Since the reasons such as insulation ag(e)ing, external force destruction, the operation time limit are, it is necessary to often carry out replacement disconnecting switch
Work.
The replacement disconnecting switch that has a power failure needs to interrupt some region of supply of electric power, influences the normal production and life of a large number of users
It is living, power supply reliability is reduced, this operating type has increasingly been not suitable with the requirement of electric company's good service and current electricity
The development trend of net, the at present maintenance for disconnecting switch are mainly carried out in a manner of livewire work.
Distribution line overhead transmission line on-load, which replaces disconnecting switch, two kinds of operating types, i.e. insulating glove working system and exhausted
Edge bar working system.Operating personnel is sent to job position and disconnecting switch is carried out more by insulating glove working system using aerial lift device with insulated arm
Operation is changed, this method operating personnel labor intensity is relatively low, but also has its limitation, when operation landform is more complicated, insulation bucket arm
When car can not be close, such a operational method can not carry out.Insulating bar operation rule limits from orographic factor, any orographic condition
Under, operating personnel need to only step on bar to job position using climbers can carry out operation, although such a operational method operating personnel labor
Fatigue resistance is relatively large, but the advantage of such a operational method is also apparent from：1）Operating personnel keeps enough safety with electrical body
Distance, electrical body is contacted by insulating bar, avoids directly contact electrical body, security higher；2）It need not set out absolutely
Edge bucket arm vehicle, operating type are more flexible.
At present, there are a technological difficulties for the work of development insulating bar method on-load replacement disconnecting switch：The phase in replacement
During disconnecting switch, due to operating personnel remove disconnecting switch when between the two phases, working space is narrow and small, while again not special
Masking apparatus two phase terminals are carried out with insulation masking, when operating personnel's operation, easily occurs with electrical body safe distance deficiency very
To the situation for directly contacting electrical body, so that Danger Electric shock risk occur.
To solve above-mentioned problem, the special isolation masking for being badly in need of being isolated switch during development insulating bar method on-load is replaced is used
Tool, to ensure livewire work personnel safety, realizes the smooth development of this work.
