Description
Technical field
The utility model relates to electrical network and hot line maintenance technical field, particularly live line working phase spacing control device on a kind of equipotential wire.
Background technology
Along with socioeconomic development, society is increasing for the demand of electric power, is impelling electrical network scale constantly to expand, the main body mode that overhead wire transmission is carried as current electric power, and line size also constantly increases thereupon.And along with the quickening of urbanization process, land resource is more and more aobvious nervous, conventional typical angle steel tower busy line channel width and steel tower are large with opening, present situation that can not adapt to economic development developed regions shortage of land resource.If but adopt steel pipe pole, although can meet the requirement that reduces floor space, steel pipe pole circuit, service condition requires high than steel tower, processing transport difficulty is large, the vertical heavy mechanical equipment that needs of group, high to job site environmental requirement, project cost is large, is unfavorable for operation maintenance.
On this basis, arise at the historic moment taking narrow base steel tube tower as the narrow base tower of example.Compared to conventional angle steel iron, steel tube tower, narrow base steel tube tower has the advantages such as little, the overall turriform of floor space is compact firmly, the exhibition of tower body arm is compact, line holding space is few, and therefore newly-increased circuit construction project more and more tends to use such turriform in recent years.
Along with the continuous lifting of society to electric power degree of dependence, it has great requirement for the quality of power supply and continued power, will cause huge economic loss and social effect once have a power failure, therefore service without power-off is safeguarded has become the conventional means that grid maintenance is safeguarded.But narrow base steel tube tower is because tower body compactness own, arm are opened up the features such as short, and the operation gap that conventional charged operational method requires cannot meet; Can say that service without power-off on narrow base tower safeguards that aspect is almost a blank field.
For the associated safety of live line working, apart from regulation requirement, on 220kV shaft tower, equipotential operating personnel should be not less than 2.5 meters to the distance of adjacent wires.The each phase conductor of narrow base tower sets up compactness, in needs personnel equipotential enters shelves when upkeep operation, maintainer deadweight adds the weight of material, Work tool etc., can cause this phase conductor sag to become large, may cause meeting equipotential personnel to adjacent wires safe distance requirement.
Utility model content
Main purpose of the present utility model is the shortcoming that overcomes prior art, provides a kind of and can really ensure that operating personnel and lower wire have enough safe distances, live line working phase spacing control device on easy to use, safe and reliable equipotential wire.
The utility model adopts following technical scheme:
Live line working phase spacing control device on equipotential wire; connected and composed by wire fixing device and insulation scale; described wire fixing device is by an insulating yoke plate and be detachably installed on the two wire holddown grooves for fixing lower wire primary and secondary line on this insulating yoke plate; described wire holddown groove is rotatably arranged at pulley and in this mount pad by a mount pad, and is detachably installed on mount pad and forms for the self-lock protection pin that prevents wire dropping, and described insulation scale is provided with the scale for identifying length.
Further, on described insulating yoke plate, offer one group of adjustment hole to regulate the distance of two wire holddown grooves.
Further, described mount pad is locked on insulating yoke plate by securing member.
Further, on the lateral wall of described mount pad, be formed with two retainer rings of the longitudinal arrangement for self-lock protection pin is installed.
Further, described self-lock protection pin is formed with the dop of the be arranged in retainer ring top that can insert the pin rod in described retainer ring and be formed at pin rod top.
Further, described insulating yoke plate upper end is formed with an insulation scale holddown groove, and described insulation scale lower end is inserted in this insulation scale holddown groove, and fixes by securing member.
Further, described insulation scale upper end is equiped with the locking device for connecting coaster.
From above-mentioned to description of the present utility model, compared with prior art, the beneficial effects of the utility model are: when use, after being adjusted according to the distance of required control, insulation scale upper end is locked on coaster, two wire holddown grooves are arranged on respectively on the lower wire primary and secondary line of work wire, when operating personnel walks on wire like this, the lower wire of operating personnel place wire can change according to the sag of operating personnel place wire, can really ensure that operating personnel and lower wire have enough safe distances, easy to use, handling safety; Meanwhile, on mount pad, be provided with self-lock protection pin, can effectively pin lower wire primary and secondary line, wire dropping when anti-locking apparatus moves, safe and reliable; Insulation scale upper end is equiped with the locking device for connecting coaster, can be connected locking with each patent block, uses more convenient.
