Description
Technical field
The present invention relates to a kind of masking device, in particular it relates to a kind of automatic traction insulating shielding device.
Background technology
Operating distribution line is to ensure uninterrupted customer power supply, it is necessary to using not power cut construction and maintenance.Wherein not
Power failure is stood, to remove electric pole task increasingly frequent.And the wide people of this project operation field is more, technical difficulty is big, and often Yao roads are narrow
Che Duo " does place where Taoist rites are performed " in the complex environments such as room Pang Shu sides are closed in snail shell.New electric pole is carried out in particularly online shelves to rise
When vertical or old electric pole is removed, it is difficult to keep electric pole and have the safe distance of electric lead.For this reason, it may be necessary to take wire exhausted Edge maskings and
The security isolation measures such as electric pole Jue Yuan Bao Li.But such a security isolation measure trivial operations, time-consuming more and used exhausted Edge maskings
The rapid wears such as blanket, produce expensive.
It is domestic do not had a power failure it is vertical, remove the wire taken during bar operation and electric pole security isolation measure and have:
1）Exhausted Edge shield tubes are installed on wire and Li insulated target patterns are wrapped on the part such as electric pole top shaft and cross-arm；
2）Exhausted Edge masks are installed on wire and in electric pole upper bar Shen Bao Li insulation sleeve patterns；
3）There is electric lead to hang three-phase using the insulation arm of aerial lift device with insulated arm to rise in waiting to stand, remove electric pole overhead pattern；
4）On jacketed wire insulation shield tube plus pull rope is tied up, exhausted Edge shield tubes are moved by pull rope by ground staff,
Keep electric pole and wire is effectively isolated pattern.
Above-mentioned preceding 1）2）The rapid wears such as kind pattern trivial operations, time-consuming more and used exhausted Edge masking blankets.3rd）Kind pattern needs
It is equipped with an aerial lift device with insulated arm more, and is suitable only for, in operation field spaciousness, to accommodate the environment of more one aerial lift device with insulated arm of fixation
Under the conditions of use.4th）Though kind of pattern is more time saving than several versions much more convenient, runs into and be just difficult to when tree or building are obstructed greatly
Implement.At present, part producing unit use jacketed Edge shield tubes absolutely on wire, and on shield tube plus tie up pull rope, it is vertical,
By personnel on ground exhausted Edge shield tubes are moved by pull rope when removing electric pole motion close to wire to keep having for electric pole and wire
The method for imitating isolation.Though the method, which compares the ways such as the exhausted Edge maskings of wire and electric pole Jue Yuan Bao Li, wants time saving much more convenient, meet
Just it is difficult to carry out when being obstructed to big tree or building.
During the vertical rod that do not have a power failure, wire is covered using conventional method, shortcoming has：
When 2.1 pairs of live wires cover, program is complicated.
Traditional wire mask is open type, and after mask is hung up properly, lower section also has gap, it is necessary to using insulated target
Mask is wrapped up again, and gap be present between two masks, it is also desirable to is further wrapped up using insulated target.
When 2.2 pairs of live wires cover, it is longer length need to be covered.
As described in first segment, for 15m electric poles, it is necessary to which the conductor length of masking is 8.48 m, masking length is spent
It is long to cause masking work to become complicated, and improve staff's work risk.
