Abstract
The invention discloses a portable special tool for the switching operation of power transformation, comprising a switching operation rod and a switching operation crank, wherein an inner hole is arranged at the center of the rod body of the switching operation rod and an end cover is arranged at the rear end of the rod body of the switching operation rod. The switching operation crank consists of a sleeve, a front handle, a middle handle and a rear handle, wherein the front end of the front handle is connected with the rear end of the sleeve, the rear end of the sleeve is rotatably connected with the front end of the middle handle through a rotation shaft; the rear end of the middle handle is rotatably connected with the front end of the rear handle through another rotation shaft; and the switching operation crank is sheathed in the inner hole of the switching operation rod so as to form clearance fit. In the invention, a combined structure is adopted and the switching operation crank is sheathed in the inner hole of the switching operation rod, so that the portable special tool is carried conveniently, the time for picking the tools are shortened and the switching efficiency is improved.
Description
One, technical field: the present invention relates to a kind of grid switching operation instrument, particularly relate to a kind of portable power transformation operation grid switching operation specific purpose tool.
Two. background technology: along with rapid economy development, people more and more pay attention to living environment and the standard of living of self, thereby the application of various electrical equipment more and more widely, this just impels network load to increase year by year, the operation power personnel according to circumstances need to carry out the power transformation grid switching operation, and have following problem at present when carrying out the power transformation grid switching operation:
1, during normal running, in case of fall bus, when stopping sending large complicated operation such as transformer, need carry a large amount of grid switching operation instruments, and these operation tool kind differences, differ in size, not portable and easy omission is left behind, in addition, also will carry other operation tools such as ground wire, electroscope, insulating bar when the operations staff carries out grid switching operation, this is very unfavorable to operation, influences service speed, thereby increase interruption duration, influence is power supply externally, the time of the system that increases electric power abnormal condition, reduces system reliability.
2, when carrying out accident treatment, need the operation power personnel fast, safety, the high-quality grid switching operation of finishing, therefore often have little time to select, carry suitable operation tool, will arrive the scene rapidly, prolong unnecessary external interruption duration sometimes because of the improper of grid switching operation instrument.
3, in substation safety Tool Cabinet management, because the grid switching operation tool shape is different, different in size, need be placed on different cabinets every interior, take up room greatly and manageability not.
Three. summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, a kind of portable power transformation operation grid switching operation specific purpose tool reasonable in design, simple in structure, easy to carry and store is provided.
Technical scheme of the present invention is: a kind of portable power transformation operation grid switching operation specific purpose tool, contain grid switching operation rod and grid switching operation crank, the barred body center of described grid switching operation rod is provided with endoporus, and the barred body rear end of described grid switching operation rod is provided with end cap; Described grid switching operation crank is by sleeve, preceding handle, middle handle and back constituting, wherein, the front end of handle is connected with the rear end of described sleeve before described, its rear end by rotating shaft with described in the front end rotary type is connected, described in the rear end by another rotating shaft with described after the handle the front end rotary type be connected; Described grid switching operation crank is sleeved in the endoporus of described grid switching operation rod, and the two is a matched in clearance.
The barred body of described grid switching operation rod is a monolithic construction.Perhaps, the barred body of described grid switching operation rod is a split-type structural, is formed by connecting by at least two rod sections.Adjacent described rod section links together by screw thread or buckle.
Described grid switching operation crank back on be set with the rotation jacket casing.
The invention has the beneficial effects as follows:
1, the present invention adopts fabricated structure, and the grid switching operation crank is sleeved in the endoporus of grid switching operation rod, is easy to carry, and shortens the time of picking instrument, improves back brake efficient.
2, grid switching operation crank of the present invention adopts the folding rotary structure, and is easy to use, puts easily, and it is little every the space to take cabinet.
3, grid switching operation rod of the present invention is a split-type structural, is made of at least two rod sections, connects by screw thread or buckle between the adjacent rod section, can dismantle, reduce to take up room, in addition, grid switching operation rod rear end is provided with end cap, prevents that effectively the grid switching operation crank from dropping out.
4, the present invention reasonable in design, simple in structure, be convenient to deposit and carry, it is applied widely, has good economic benefit after the popularization.
