Description
Technical field
The utility model relates to a kind of power transmission and distribution outdoor switch device, belong to power transmission and distribution outdoor switch device technical field.
Background technology
Growing along with Urban and rural area electricity needs, has proposed high requirement to the fail safe of power transmission and distribution system and power supply supportability.The electric power terminal power equipment used of city and country electrical network is to be fixed on electric pole mostly at present, or builds power distribution room.Be fixed on switchgear on electric pole in running, repair and maintenance all needs equipment staff first to climb up after electric pole, can bring great personal safety hidden danger, simultaneously due to limited space on electric pole, and operation inconvenience, the repair and maintenance time is long.Build power distribution room, taken a large amount of soils, simultaneously also there is larger potential safety hazard in the management aspect for everyday devices, and for example layman is strayed in power distribution room or neighbouringly may causes electric shock accidents.
Summary of the invention
The utility model proposes a kind of outdoor pole top switch equipment, its object is to overcome the above-mentioned defect of the existing folding of prior art, has the advantages that repair and maintenance is convenient, save land used.
Technical solution of the present invention: a kind of outdoor pole top switch equipment, its structure comprises line bar, main switch, fixed contact and moving contact, wall bushing is installed in described line bar upper end, electric-conductor is equipped with in wall bushing inside, electric-conductor one end is connected with aerial cable, the electric-conductor other end is fixed contact, in line bar, the guide rail of vertical direction is equipped with in lower end, bracing frame is arranged on guide rail, guide rail is for support and the lifting of bracing frame simultaneously, and lifting stings tooth by lifting and the mutual occlusal contact condition of motor gear is realized, on bracing frame, be installed with main switch, main switch is provided with moving contact.
Advantage of the present utility model: move in the vertical direction along guide rail by bracing frame, can realize whole distribution system working position, isolated bit and three of maintenance positions working position, broken the direct-connected mode of conventional main switch and cable, realized the socket connection of main switch and cable, solved electric pole and built the existing defect of power distribution room two aspect supply power mode.Service work position almost approaches ground, and equipment management personnel can carry out inspection and maintenance to equipment on the ground, and it is very convenient to operate, and saves time, safety.In the situation that transmission line or higher level, subordinate's power equipment break down, this switchgear can move to isolated location, avoids spreading of electric power accident.Except safeguarding, maintenance, switchgear substantially mostly the time all in service position, reduced floor space, also avoided layman's false touch charging equipment.
This outdoor pole top switch equipment, support movements can be by dependent manual operation or electric operating.
Can make-up machinery locking device between bracing frame and guide rail, when main switch moves to maintenance, isolation and service position, mechanical locking device will lock bracing frame, prevents landing.Electric interlocking installation is also housed between main switch and bracing frame, thereby has guaranteed to need only main switch at closing position, bracing frame just can not move, and that is to say and only has main switch in open position, and bracing frame could move between three service positions.

In figure 1 is line bar, the 2nd, wall bushing, the 3rd, main switch, the 4th, bracing frame, the 5th, guide rail, the 6th, fixed contact, the 7th, moving contact.
Embodiment
As Figure 1-3, outdoor pole top switch equipment, its structure comprises line bar 1, main switch 3, fixed contact 6 and moving contact 7, wall bushing 2 is installed in the upper end of described line bar 1, the inner electric-conductor of installing of wall bushing 2, one end of electric-conductor is connected with aerial cable, the other end of electric-conductor is as fixed contact 6, in line bar 1, the guide rail 5 of vertical direction is equipped with in lower end, bracing frame 4 is arranged on guide rail 5, guide rail 5 is for support and the lifting of bracing frame 4 simultaneously, and on guide rail 5, be designed with lifting and sting tooth, by lifting, sting the lifting that tooth and the mutual occlusal contact condition of motor gear are realized bracing frame 4, on bracing frame 4, fixedly mount main switch 3, on main switch, 3 are provided with moving contact 7.
Can make-up machinery locking device (existing) between described bracing frame and guide rail, when main switch moves to maintenance, isolation and service position, mechanical locking device will lock bracing frame, prevents landing.
Electric interlocking installation (existing) is also housed between described main switch and bracing frame, thereby guaranteed to need only main switch at closing position, bracing frame just can not move, and that is to say and only has main switch in open position, and bracing frame could move between three service positions.
Outdoor pole top switch equipment moves along guide rail in the vertical direction by bracing frame, can realize whole distribution system working position, isolated bit and three of maintenance positions working position.When motor gear forward rotation, motor gear stings with lifting that tooth is engaged to be contacted, and drives lifting to sting tooth to rise one by one, thereby bracing frame is upwards risen; Otherwise when power supply gear counter-rotation, motor gear stings with lifting that tooth is engaged to be contacted, and drive lifting to sting tooth to decline one by one, make to throw bracing frame and decline, thereby realized bracing frame, along guide rail, move in the vertical direction.
As Figure 1 and Figure 4, when 3 power-off of needs main switch, bracing frame 4 drops to main switch 3 isolated locations along guide rail 5, and when declining, bracing frame 4 drives main switch 3 to decline, and while main switch 3 drive moving contacts 7 decline and separate with fixed contact 6.
As shown in Fig. 3, Fig. 6, when main switch 3 need to overhaul because of fault, bracing frame 4 drops to main switch 3 maintenance positions along guide rail 5, and when decline, bracing frame 4 drives main switches 3 to decline, and main switch 3 drives moving contact 7 declines to separate with fixed contact 6 simultaneously.
As shown in Fig. 2, Fig. 5, after maintenance, during power transmission, bracing frame 4 rises to main switch 3 make positions along guide rail 5, and when bracing frame 4 rises to main switch 3 service position, main switch 3 drives moving contacts 7 and fixed contact 6 closures.
This outdoor pole top switch equipment has solved electric pole and has built the existing defect of power distribution room two aspect supply power mode.Effectively improve overhaul efficiency, ensured power supply capacity, also eliminated the potential safety hazard of bringing to maintenance worker because of live line working, reduced floor space simultaneously.
