Description

A kind of overhead transmission line equipotential live line work obstacle detouring rotation coaster and method
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.

8. a kind of overhead transmission line equipotential live line work obstacle detouring rotation coaster as claimed in claim 7, characterized in that the pedestal Using circular base, the connection of the circular base and coaster body inner surface is fixed using riveting.
9. a kind of overhead transmission line equipotential live line work obstacle detouring rotation coaster as claimed in claim 4, characterized in that described progressive The track depth of track is different, and wherein one end is shallower, gradually deepens to the other end, and shallower one end is track steady state point, more deeply One end be track limit point;
Entrance for being put into the track end of rail link is set at track limit point, is fixed on lock modules using bolt At track limit point;
The cross section of progressive track uses the relatively large triangular-section of forced area, convenient for undertaking from the exhausted of rail link Pulling force in edge transmission rope, the weight of rope ladder and operational process.
10. a kind of overhead transmission line equipotential live line work obstacle detouring operational method of rotation coaster, characterized in that include: to pass insulation Rope is passed to be hung on rail link;
It is adjusted the angle by insulating bar, so that helical duct main body is located at immediately below coaster main body, and makes conducting wire and spiral shell It is parallel to revolve channel body, rotation coaster is hung on conducting wire;
Insulating bar is taken out, and insulation transmission rope is slowly transferred into ground;
Along conducting wire, insulation transmission rope is pulled to maintenance position, under the action of universal rolling wheel, so that rotation coaster moves ahead;
When rotation coaster advances to sub- conductor spacer, sub- conductor spacer enters rotation by helical duct entrance in coaster main body and slides Vehicle;
Insulation transmission rope is pulled on, sub- conductor spacer contacts generation with helical duct in coaster main body perpendicular to contact surface at this time Active force, radial component to rotate the rotation of coaster stress;
Rotate coaster obstacle detouring during, rail link under the action of pulling force along progressive orbit rotation so that rail link Always in the underface of rotation coaster;
After rotation coaster crosses sub- conductor spacer, insulation transmission rope is pulled on, rail link is under the action of pulling force along progressive Track opposite direction rotation, until the track end of rail link returns the track steady state point of progressive track;
Continue to pull insulation transmission rope and obstacle detouring to maintenance position, until rotation coaster marches to maintenance position;
Rope ladder is hung using the insulation transmission rope on rail link, then enters strong electrical field along rope ladder and carries out equipotential live line work inspection It repairs.
