Abstract
The utility model discloses a special tool for installing a fuse protector. The special tool comprises a switching rod with a push-pull head at one end, wherein a U-shaped open-ended steel clip matched with a fusion tube of the fuse protector is arranged at the upper end of the switching rod, is fixedly arranged on the switching rod through a sticky chain and is riveted with the sticky chain. The special tool has the advantages of simple structure, operation convenience and reliability, and time and labor are saved, and the fuse protector cannot be dropped and damaged, so that the waste is avoided, the cost is saved, and the safety of personnel and equipment is better guaranteed.
Description
Technical field
The utility model relates to the special operating tool that carries out Maintenance and Repair in a kind of transmission line, a kind of specifically specific purpose tool of installing or changing fuse switch.
Background technology
Fuse is widely used in high and low voltage electric distribution system and control system and the power consumption equipment, as the protector of short circuit and overcurrent, is to use one of the most general protection device.Fuse is a kind of overcurrent protective device.Fuse mainly is made up of melt and fusion tube and outer part such as filled.At present, in the distribution transformer of a large amount of operations of China, the high-pressure side all is equipped with RW series outdoor drop-out type fuse, as the short circuit and the overladen protection of transformer.Because its fuse setting height(from bottom) is higher, need the dismounting fusion tube when breaking down because of repair and maintenance or a variety of causes simultaneously.For a long time, use during the dismounting fusion tube brake pull-rod of insulation to carry out.The top of brake pull-rod fixedly install being useful on operate a switch the operation etc. the push-and-pull head.The push-and-pull head is made up of two mutually perpendicular metal tubes, and wherein a metal tube is provided with along the brake pull-rod direction, and another metal tube is vertical with brake pull-rod to be provided with.Need fusion tube is suspended on the push-and-pull head place on brake pull-rod top during use, set up by provoking of manual work afterwards and install or change fuse.In installing process,, cause that easily fusion tube plays pendulum because brake pull-rod and fusion tube are to contact, the size and the balance of the very difficult assurance dynamics of operating personnel, very easily landing break fusion tube, injure personnel by a crashing object, damage equipment.
The utility model content
The utility model technical issues that need to address provide the specific purpose tool that fuse is installed in a kind of simple in structure, easy to operate being used to.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The specific purpose tool of fuse is installed, is comprised that an end is provided with the brake pull-rod of push-and-pull head, the upper end of said brake pull-rod is provided with the opening steel card of the U type structure that cooperates with the fusion tube of fuse.
The further improvement of the utility model is: said opening steel cartoon is crossed sticking chain and is fixedly mounted on the brake pull-rod; Opening steel card and the riveted joint of sticking chain.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model has designed the opening steel card of the U type structure that cooperates with the fusion tube of fuse; Fasten the opening steel at brake pull-rod with sticking chain during use, fuse tube is stuck in the opening steel card, be convenient to operation; And stability and safety is stuck in the position on the brake pull-rod but also can easily adjust the opening steel.The utlity model has simple in structure, easy to operate, reliable, time saving and energy saving advantage, and can not cause fuse to fall damage, avoid waste, practice thrift cost, guaranteed the safety of personnel and equipment more.
