Abstract

The invention relates to a horizontal drop fuse, comprising an insulated porcelain column, a fuse tube and two end connection terminals, wherein a fuse is arranged in the fuse tube; the insulated porcelain column and the fuse tube are placed horizontally, one end of the fuse tube is connected with a head chuck, the other end of the fuse tube is connected with one end of a conductive arm, and the other end of the conductive arm is connected with a tail suspender; and a contact and a reed are arranged between the conductive arm and the tail suspender. Because the fuse tube is placed horizontally, the operation angle of a pull rod is very good, and the fuse can be conveniently opened or closed. The horizontal drop fuse also facilitates visual check of equipment due to good observation angle.

Description

technical field [0001] The invention relates to a fuse, in particular to a horizontal drop-out fuse. Background technique [0002] Such as figure 1 As shown, the drop-out fuse in the prior art generally installs the support iron of the fuse at the upper and lower ends of the insulating ceramic column, and the fuse tube is fixed on the fuse through the contact spring at the upper end, the hanging hook, the pressure plate and the shackle at the lower end. On the device, when the fuse is blown, the lower locking mechanism will loosen, and under the influence of gravity, the upper end of the fuse tube will be separated from the upper hanging hook, and the entire fuse tube will swing in a circular arc around the lower hook ring as the center. hanging on the fuse. Since the inclination angle a is 20-30 degrees during design and installation, and the installation position of the fuse is very high, when the personnel use the operating lever for power transmission operation, the op...
