Mainly aiming at the defect of difficult arc extinction for live working in the prior art, the utility model provides the equipotential live working copper pulley which is provided with a pulley and can solve the problem of difficult arc extinction for live working of the tubular busbar thoroughly. The main scheme of the utility model is as follows: one end of circular and tubular busbar hardware is in hinge connection, and the other end of the circular and tubular busbar hardware is fastened by a bolt; the tubular busbar hardware is provided with a connecting plate; and the connecting plate is fixedly connected with a metal hanging frame, a wheel shaft is movably connected with the metal hanging frame by a movable linking component, and is provided with the pulley.
Description
Technical field
The utility model relates to a kind of electric armour clamp, the equipotential live line working copper coaster of tube type bus live line working special use in especially a kind of transformer station.
Background technology
20 beginnings of the century, world developed country has started the technology of carrying out live line working on power equipment.The 1950's, the live line working technology has been studied successfully also because of industrial needs by China, and in the inner popularization of electric power system, has passed through semicentennial practice and experimental study, and the live line working technology in circuit and distribution field is very ripe.
Present stage, along with system improves constantly the requirement of power supply reliability, live line working day by day causes people's attention in the transformer station.Based on power supply reliability, the requirement of power engineering fail safe, the problem of wiring live line working extinguishing arc difficulty is the difficult problem that power domain needs to be resolved hurrily on the tube type bus.
Summary of the invention
The utility model is primarily aimed at the shortcoming of live line working extinguishing arc difficulty in the prior art, provides a kind of with equipotential live line working copper coaster pulley, that can thoroughly solve a tube type bus live line working extinguishing arc difficult problem.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs: a kind of equipotential live line working copper coaster, it is characterized in that, one end of annular pipe capital tool is made as loose-leaf and connects, the other end passes through bolted, pipe capital tool has connecting plate, a connecting plate and a metal hanger are affixed, have a wheel shaft to flexibly connect by active link assembly and metal hanger, and pulley is set on the wheel shaft.
As preferably, described metal hanger is one-body molded by two orthogonal metallic plates.
As preferably, in the described metal hanger vertically towards vertical metallic plate and connecting plate affixed, level towards the horizontal metal plate on connect wheel shaft.
In sum, the utility model is compared with prior art has following advantage: the utility model electric conductivity is good, flexible during use, convenient, set up the problem of coaster assembly at wiring live line working extinguishing arc difficulty on the tube type bus, researched and developed special-purpose equipotential copper coaster, thoroughly solve the extinguishing arc problem of tube type bus live line working, greatly improved the fail safe of tube type bus live line working safety.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, 2, equipotential live line working copper coaster, manufacturing materials is a brass all, utilizes the good electric conductivity of brass, the equipotential condition in the live line working process; Annular pipe capital tool 2 can be opened entire semicircular ring by two and constitute, and the lower end is that loose-leaf 5 connects, and the upper end is fastening by bolt 3, improves ease of use, flexibility when keeping fixation.
Described annular pipe capital tool 2 have vertically towards connecting plate 1, one metal hanger 7 is arranged, one-body molded by two orthogonal metallic plates, its vertically towards vertical metallic plate 9 fixedly connected with described connecting plate 1, its level towards horizontal metal plate 8 on flexibly connect wheel shaft 4, pulley can rotate by 360 degree on horizontal plane, can swing to both sides on perpendicular.
Pulley 6 is installed on described wheel shaft 4, and the extinguishing arc rope is wrapped on the pulley 6, can play quick deciliter process by pulley 6 and reach effective extinguishing arc, avoids in the extinguishing arc process equipotential operating personnel being damaged, and reduces the security risk of tube type bus live line working.
As shown in Figure 4, during use, equipotential live line working copper coaster is fixed on by pipe capital tool 2 to be needed on the pipe of the live line working mother 10, the copper coaster by pipe capital tool 1, connecting plate 2, metal hanger 7 reaches and manage female equipotential condition; Chargedly do the time spent, charged disconnecting no-load current all can produce electric arc on the disconnecting point, and need 11 guide functions of extinguishing arc rope this moment, prevents that no-load current from passing through the screening clothing water conservancy diversion; During extinguishing arc, extinguishing arc rope 11 is wrapped on the pulley 6, can play quick deciliter process by the copper coaster and reach effective extinguishing arc, avoids in the extinguishing arc process injury to the equipotential operating personnel.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
