The wind power station special-purpose drop-out fuse has strong wind resistance capacity, can effectively avoid misoperation and is suitable for the places such as wind power stations, remote power stations, etc.
Description
Technical field
The utility model relates to electric device manufacturing technology field, especially a kind of fuse switch that is applied to wind energy turbine set.
Background technology
Fuse switch is the most frequently used a kind of protective switch of the short circuit of high-tension distributing line branch line and distribution transformer; it have economy, easy to operate, adapt to the features such as outdoor environment is strong, be widely used in high-tension distributing line and distribution transformer primary side as protection and carry out equipment throwing, cut the use of operation.Its fusion tube of traditional fuse switch and moving contact are disjunctor designs, moving contact is arranged on the upper end of fusion tube, the upper end of moving contact is that the mode of exerting pressure by Compress Spring contacts with the upper conducting strip of inlet wire seat, while installing, fusion tube also has the inclination angle of downward 25 ° of left and right simultaneously, and while fusing in order to melt, fusion tube can rely on own wt to fall rapidly.But this traditional fuse switch, under inclement weather conditions or in the larger place of wind-force, due to reasons such as the shake of body wind-engaging, Compress Spring lost efficacy, electric conductor is overheated, very easily causes fusion tube to fall by mistake, causes unnecessary economic loss.
Utility model content
The technical problems to be solved in the utility model is to provide the special-purpose fuse switch of a kind of wind field, and wind loading rating is strong, effectively prevents misoperation, is applicable to being applied to the places such as wind energy turbine set and outlying power station.
For achieving the above object, the technical solution of the utility model is: the special-purpose fuse switch of a kind of wind field, comprise " [" shape support, the interlude of support is insulator, the middle part of support interlude outwards connects a mounting panel, an inlet wire seat is fixed in the upper end of support, a wire outlet seat is fixed in the lower end of support, the lower end of one fusion tube is hinged on wire outlet seat by fusion tube fixed mount, the upper end of fusion tube is connected with the lower end of a moving contact, moving contact is connected on inlet wire seat, the top of moving contact is pushed down by a upper conductive plate being connected on inlet wire seat, between upper conductive plate and inlet wire seat, stage clip is housed, the outside of moving contact is provided with draw ring, the clip of a U-shaped is fixed in the bottom of inlet wire seat, two sides of clip are provided with draw-in groove, moving contact both sides are radially provided with two clamping projections and match with the draw-in groove of two sides of clip, the upper end of described fusion tube is entrenched in the lower end of moving contact in separable mode, outside, fusion tube upper end is provided with draw ring.
Further improve, the angle of described mounting panel and support interlude is 90 °.Further prevent that fusion tube from falling by mistake.
Further improve, fusion tube fixed mount and wire outlet seat are hinged by a bearing pin, and torsion spring is housed on bearing pin, and torsion spring one end is pressed on fusion tube fixed mount, the other end is pressed on wire outlet seat.The torsion applying by torsion spring after fusion tube fusing is reliably fallen, guarantee the reliability of action.
The utility model is because the clip of a U-shaped is fixed in the bottom of inlet wire seat, and two sides of clip are provided with draw-in groove, and moving contact both sides are radially provided with two clampings projections and match with the draw-in groove of two sides of clip; So just can guarantee that moving contact is effectively connected on inlet wire seat, prevent from, because the reasons such as the shake of body wind-engaging, Compress Spring lost efficacy, electric conductor is overheated cause fusion tube to fall by mistake, avoiding unnecessary economic loss.
On the other hand, because the upper end of described fusion tube is entrenched in the lower end of moving contact in separable mode, when fusion tube fuse failure, even in the situation that upper contact head and upper incoming line seat do not depart from, fusion tube also can effectively fall, guarantee the reliability of action.
Through test, the utility model can effectively be resisted wind speed and be not more than the large wind effect of 50m/s, and wind loading rating is strong.This product can be widely used in the places such as wind energy turbine set and outlying power station.
