Description
Technical field
This disclosure relates to which transmission facility power tool technical field, gets over more particularly to a kind of overhead transmission line equipotential live line work
Barrier rotation coaster and method.
Background technique
Electrical equipment needs often maintenance, defect elimination in longtime running, and with the fast development of electric system, user is to confession
The requirement of electric reliability is continuously improved, and finds that defect, elimination defect become the weight of power transmission line road transport inspection person works in time
Point, livewire work are that maintenance is avoided to have a power failure, and guarantee the effective means of electric system uninterrupted power supply.Operating personnel is pressed in livewire work
Human-body potential divide, equipotential live line work, medial potential working and earth potential working can be divided into.Wherein, equipotential live line work is also referred to as
For direct maintenance, refer to that operating personnel makes the current potential of oneself body rise to electrification position current potential, and with different potentials around
It is properly isolated from, the operation that directly live part is carried out.
The method that equipotential live line work enters electric field, which mainly has, to be entered along insulated flexible ladder, enters along strain insulator string, hanging basket
Method enters and enters along flat ladder.Wherein, it is most widely used along the method that insulated flexible ladder enters electric field, tangent tower, anchor support
It can be used.Enter the operating procedure of electric field along insulated flexible ladder are as follows: 1) using insulating bar by be installed with insulation transmission rope with
Bucket coaster is suspended on conducting wire;2) somersault coaster is pulled to by upkeep operation position by insulation transmission rope;3) using somersault coaster and
Insulated flexible ladder is promoted to lead location by the transmission rope that insulate;4) insulated flexible ladder is hung up properly, operating personnel climbs rope ladder and enters electric field.
35kV and the above transmission line of electricity are to inhibit corona discharge and reduce line reactance at present, mostly use split conductor, edge
When insulated flexible ladder enters electric field, somersault coaster can not cross the sub- conductor spacer in split conductor since self structure limits, thus
So that rope ladder must be hung in advance, operating personnel enters strong electrical field along rope ladder in advance, encounters sub- conductor spacer and needs first to tear it into place open,
Rope ladder reinstalls sub- conductor spacer after passing through, and rope ladder is gradually moved to maintenance position, operating personnel is considerably increased and exists
Operation intensity and activity duration in strong electrical field, not only will affect working efficiency, but also increase operating risk.
Influence about split conductor to rope ladder is hung, can be divided into two kinds of situations: the first situation be conductors on quad bundled and
The conducting wire of higher division number, operating personnel can along conducting wire steadily rapidly from rope ladder hang position walking to maintenance position, because
This position for hanging rope ladder influences little;Second situation is double bundle conductor, and operating personnel can not be in conducting wire in such cases
Upper steady walking, hanging position to rope ladder has certain requirement, while somersault coaster can not cross sub- conductor spacer, is that equipotential is made
Situation the most difficult and complicated in industry.
Disclosure
In order to solve the deficiencies in the prior art, present disclose provides a kind of rotations of overhead transmission line equipotential live line work obstacle detouring to slide
Vehicle solves the problems, such as that traditional somersault coaster can not cross double bundle conductor neutron conductor spacer.
