Abstract
The utility model discloses an outdoor low-voltage distribution switch box which is characterized in that: a piece of angle steel is provided with a side plate with a slide way; a pulley is capable of free horizontal movement inside the slide way; both ends of the pulley are respectively provided with a bearing; the middle part of the pulley is provided with a fixed groove capable of clamping a moving contact fixed plate; both ends of the moving contact are provided with copper-tungsten contacts; on side of a main shaft is welded with a stop piece; moreover, the main shaft is also welded with two poking forks. Due to adopting a disconnector system capable of free horizontal movement, the utility model is an important device used in the low-voltage leading-out terminal of a transformer inside a low voltage network; moreover, the utility model not only has short circuit and overcurrent protection, but also can realize on-load opening and closing operation outside the switch box; therefore, the utility model, which ensures the personal safety of staff during operation, reduces contact cautery caused by arc during switch opening and closing, and is convenient for popularization.
Description
Technical field
The utility model relates to a kind of distribution transforming switch-box, and particularly a kind of outdoor low voltage distribution transforming switch-box belongs to the technical field of power industry outdoor low voltage switch aspect.
Background technology
In electric power system distribution transforming equipment, though outdoor low voltage distribution transforming switch-box manufacturer is a lot, the distribution transforming switch-box of producing is roughly the same, all exist the defective and the component quality of institute's type selecting in the design poor, cause that easily the temperature inside the box is too high, the contact of current-carrying part generates heat easily, and the fault that causes burning takes place, have much room for improvement at design aspect.
Summary of the invention
Deficiency at above-mentioned technology existence, the utility model provides a kind of outdoor low voltage distribution transforming switch-box, comprise angle steel, channel-section steel, the insulator installing hole, side plate, slideway, main shaft, shift fork, the energy storage control piece, auxilliary axle, pin, stop bit spare, installing hole, bearing, pulley bracket, holddown groove, insulator, lead-in line row, the outlet seat, following arc cover holder, static contact, the spring iron plate, supporting bracket, the striking fingertip, the copper-tungsten contact, moving contact, the fuse fastening bolt, the moving contact pressing plate, the moving contact fixed head, pulley, it is characterized in that: the side plate that the band slideway is installed on angle steel, pulley freely moves horizontally in slideway, two ends at pulley are separately installed with bearing, be provided with the holddown groove that can block the moving contact fixed head at the middle part of pulley, be provided with the copper-tungsten contact at the two ends of moving contact, face down bonding at main shaft is connected to stop bit spare, also is welded with two shift forks on main shaft.
The utility model is the important device of transformer low voltage leading-out terminal in the low-voltage distribution electrical network because of having adopted the disconnecting link system that can freely move horizontally, existing short circuit and overcurrent protection, but on-load is realized branch, closing operation in the switch-box outside again.Thereby guaranteed the personal safety of staff when operation, also reduced the switch branch, the fashionable contact that causes because of arcing burns phenomenon, be convenient to promote the use of.
