Abstract
The utility model relates to a high-pressure disconnection switch. According to the utility model, a pair of insulation uprights (2) is respectively arranged on a base (1), a pair of conductive rods (3) is respectively arranged on the insulation uprights (2), a lifting device (4) is arranged on the base (1), and is positioned between the insulation uprights (2), an insulation support frame (5) is arranged on the lifting device (4), a conductive cross rod (6) is arranged on the insulation support frame (5), and the two ends of the conductive cross rod (6) are respectively provided with a spring contact finger A (6-1) and a spring contact finger B (6-2). The utility model has the advantages that when the disconnection switch is detected and maintained, only through operating the lifting device, the spring contact fingers on the conductive cross rod are separated from the conductive rods, then the conductive cross rods are disassembled, and the damaged parts can be detected and maintained; the detection and the maintenance are convenient; and time and labor saving is realized.
Description
Technical field
The utility model relates to electric switch protective device field, relates in particular to a kind of high pressure and uses isolation switch.
Background technology
At present; Isolation switch on the existing 35-110 kilovolt high-tension line is made up of insulation column, conducting rod and fingertip; Conducting rod and fingertip are installed in respectively on the insulation column, thereby conducting rod is separated with fingertip and contact the purpose that reaches combined floodgate and disjunction through rotating the insulation column.Put into practice from power transformation, there are two major defects in present widely used high pressure isolation switch: the one, and movable device is prone to bite, because the long-time inoperation of isolation switch; And the movable part long term exposure is in air; Thereby cause the movable part corrosion to cause bite, for this defective, at present part producing producer is existing is familiar with and it has been carried out some improvement; But, can not tackle the problem at its root owing to structural reason; The 2nd, maintenance inconvenience needs long interruption maintenance, and fingertip is the consumable accessory of isolation switch, to the effect that fingertip being changed or adjusted of maintenance.When big load, fingertip heating phenomenon is more general, and just need overhaul it this moment, but present isolation switch structure makes it have a power failure and could overhaul through the long period; For inlet wire side tool lock and female disconnecting link that joins, then need full station to have a power failure and to overhaul.In sum, the existing main weak point of high pressure disconnecting link is that on 35-110 kilovolt high-tension line, when handling disconnecting link fault and defective, the maintainer is easy-maintaining not.
The utility model content
The purpose of the utility model is exactly to existing bus bar side disconnecting link not, and on 35 kilovolts of high-tension lines, when handling bus bar side disconnecting link fault, operating personnel are the deficiency of easy-maintaining and detection not, and provides a kind of high pressure to use isolation switch.
The utility model is made up of base, a pair of insulation column, pair of conductive bar, lowering or hoisting gear, insulation bracing frame, conduction cross bar, A spring touch finger and B spring touch finger; A pair of insulation column is installed in respectively on the base, and the pair of conductive bar is installed in respectively on a pair of insulation column, and lowering or hoisting gear is installed on the base; Between a pair of insulation column; The insulation bracing frame is installed on the lowering or hoisting gear, and the conduction cross bar is installed on the insulation bracing frame, and conduction cross bar two ends are separately installed with A spring touch finger and B spring touch finger; The A spring touch finger is corresponding with the pair of conductive bar respectively with the B spring touch finger, and the conduction cross bar is movably arranged on the insulation bracing frame.
The utility model advantage: when detecting and keep in repair isolation switch; Only need through the operation lowering or hoisting gear, the insulation bracing frame on the lowering or hoisting gear is descended, and then the spring touch finger on the conduction cross bar is separated with conducting rod; The cross bar that will conduct electricity then disassembles; Broken parts is detected maintenance get final product, the convenient detection keeped in repair, and be time saving and energy saving.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1; The utility model is made up of base 1, a pair of insulation column 2, pair of conductive bar 3, lowering or hoisting gear 4, insulation bracing frame 5, conduction cross bar 6, A spring touch finger 6-1 and B spring touch finger 6-2; A pair of insulation column 2 is installed in respectively on the base 1, and pair of conductive bar 3 is installed in respectively on a pair of insulation column 2, and lowering or hoisting gear 4 is installed on the base 1; Between a pair of insulation column 2; Insulation bracing frame 5 (insulation bracing frame 5 is the dismounting parts) is installed on the lowering or hoisting gear 4, and conduction cross bar 6 is installed on the insulation bracing frame 5, and conduction cross bar 6 two ends are separately installed with A spring touch finger 6-1 and B spring touch finger 6-2; A spring touch finger 6-1 is corresponding with pair of conductive bar 3 respectively with B spring touch finger 6-2, and conduction cross bar 6 is movably arranged on the insulation bracing frame 5.
Operation principle: when detecting and keep in repair isolation switch; Only need through the operation lowering or hoisting gear, the insulation bracing frame on the lowering or hoisting gear is descended, and then the spring touch finger on the conduction cross bar is separated with conducting rod; The cross bar that will conduct electricity then disassembles, and broken parts is detected maintenance get final product.
