Abstract
A hand-cranked high-voltage switch cabinet door opener is used to solve a problem of fast loosening or fastening of fastening bolts of a high-voltage switch cabinet door. The hand-cranked high-voltage switch cabinet door opener is composed of a key head, a connecting rod, a handle shaft and a handle shaft sleeve. The key head is fixed at one end of the connecting rod, the handle shaft is fixedly installed at the other end of the connecting rod, and the handle shaft sleeve is sleeved outside the handle shaft. The hand-cranked high-voltage switch cabinet door opener is simple in structure and easy to operate; not only labor intensity of operators is reduced, but also a required opening time and a required closing time of high-voltage switch cabinet door of a transformer substation are shortened; and, it has been verified that only less than 25 seconds are needed to complete loosening or fastening operation of the fastening bolts on one surface of a switch cabinet, so that work efficiency is improved more than three times.
Description
Technical field
The utility model relates to a kind of transformer station high-voltage board door opener, and the opener of especially a kind of hand-rail type transformer station high-voltage board door belongs to generating, power transformation or distribution technique field.
Background technology
Requirement according to " power transmission and transforming equipment anti-accident measures ", the 12kV of transformer station～40.5kV enclosed switchgear is need be with cabinet door lock dead and by the bolted of sufficient intensity, when effectively preventing in the switch cubicle equipment short circuit accident, electric arc and high pressure-temperature gas impact cabinet, make the cabinet door open or produce deformation, electric arc and high pressure-temperature air-flow cause personal injury by the slit of cabinet door or cabinet door to operating personnel before cabinet.Therefore on every fan front cabinet door of switch cubicle three fastening bolts are set at least, namely upper, middle and lower portion is each one.Open at switch cubicle, during closed operation, need to insert in the keyhole that arranges on transformer station's high-voltage board door by the key of special use, the rotation of drive fastening bolt, make fastening bolt loosening or fastening (as accompanying drawing 1, shown in 2), but the operating side of this private key is stationary structure, directly controlled by staff, can not realize continuous rotation, and operate dumb, loosening or the fastening operation of finishing at least six fastening bolts on the switch cubicle (being provided with two fan cabinet doors) approximately needs the time in 75 seconds, and whole transformer station has 20 multiaspect switch cubicles at least, operation field for the power failure of full station, only open the cabinet door and just need take 1 time that the people is about about 35 minutes, not only labor intensity of operating staff is big, and inefficiency.
The utility model content
The purpose of this utility model is the drawback at prior art, provide a kind of simple in structure, easy to use, can shorten transformer station's high-voltage board door open and close required time, significantly improve the hand-rail type high-tension switch cabinet door opener of operating efficiency.
Problem described in the utility model realizes with following technical proposals:
A kind of hand-rail type high-tension switch cabinet door opener, it is made up of key bit, connecting rod, Handle axis and handle axle sleeve, described key bit is fixed on connecting rod one end, the other end fixed installation Handle axis of described connecting rod, the outside suit handle axle sleeve of described Handle axis.
Above-mentioned hand-rail type high-tension switch cabinet door opener, described key bit front end are " φ " type structure, the keyhole coupling on it and the transformer station's high-voltage board door.
Above-mentioned hand-rail type high-tension switch cabinet door opener, described connecting rod is the rectangular tube structure, described key bit and Handle axis are fixedly mounted on the both sides of connecting rod respectively.
Above-mentioned hand-rail type high-tension switch cabinet door opener, described handle axle sleeve and Handle axis are with the gap fiting mode suit, and described Handle axis end is the orbicule structure.
The utility model is formed a laborsaving leverage by key bit, connecting rod and Handle axis, has lengthened the active arm of force of leverage by connecting rod, has reduced to make the loosening or fastening operating physical force of fastening bolt; The utility model is by the matched in clearance assembling mode of handle axle sleeve and Handle axis, handle axle sleeve and Handle axis can be relatively rotated, therefore the spinning movement of operating personnel's energy continuous control key bit is rotated continuously thereby drive fastening bolt, finishes the loosening or fastening operation of fastening bolt fast.The utility model is simple in structure, easy to operate, can not only reduce labor intensity of operating personnel, and shortened transformer station's high-voltage board door open and close required time, through checking on probation, finishing the loosening or fastening operation that a switch cubicle tightens bolt only needs less than 25 second time, make operating efficiency improve more than three times.
