Outdoor pole top switch device

Abstract

The invention discloses an outdoor pole top switch device. The outdoor pole top switch device structurally comprises wire poles (1), a main switch (3), fixed contacts (6) and moving contacts (7), wherein a wall bushing (2) is arranged at the upper end of each wire pole (1), an electric conduction piece is arranged inside each wall bushing (2), one end of each electric conduction piece is connected with an aerial cable, and the other end of each electric conduction piece is used as one of the fixed contacts (6). A guide rail (5) which is in the perpendicular direction is arranged at the middle lower end of each wire pole (1), a supporting frame (4) is arranged on the guide rails (5), meanwhile, the guide rails (5) are used for supporting the supporting frame (4) and enabling the supporting frame (4) to rise and fall, and the rising and the falling of the supporting frame (4) are achieved by enabling rising and falling biting teeth to mesh with and make contact with motor gears. The main switch (3) is fixedly arranged on the supporting frame (4), and the moving contacts (7) are arranged on the main switch (3). The outdoor pole top switch device has the advantages that the defects caused by two power supply modes, namely, the mode of supplying power through telegraph poles and the mode of supplying power by constructing transformer rooms are overcome, the device is convenient to operate and maintain, and the occupied land can be saved.

Description

technical field [0001] The invention relates to an outdoor switchgear for power transmission and distribution, which belongs to the technical field of outdoor switchgear for power transmission and distribution. Background technique [0002] With the increasing demand for electricity in cities and rural areas, higher requirements are placed on the safety and power supply guarantee capabilities of power transmission and distribution systems. At present, most of the power equipment used in the power terminals of urban and rural power grids are fixed on utility poles or build power distribution rooms. During the operation of the switchgear fixed on the utility pole, inspection and maintenance requires the equipment staff to climb on the utility pole first, which will bring great personal safety hazards. long time. Building a power distribution room takes up a lot of land. At the same time, there are greater safety hazards in the management of daily equipment. For example, non-...

During the operation of the switchgear fixed on the utility pole, inspection and maintenance requires the equipment staff to climb on the utility pole first, which will bring great personal safety hazards. long time

Building a power distribution room takes up a lot of land. At the same time, there are greater safety hazards in the management of daily equipment. For example, non-professionals may cause electric shock accidents if they stray into or near the power distribution room.
