According to the insulated operation rod head for mounting of the insulated knife switch protection cover, when a maintenance person mounts the protection cover, insulation with the charged part can be effectively carried out, the maintenance person can be ensured to be in the safe distance to carry out mounting operation on the protection device, the insulated protection cover can be mounted at any time, bird damage fault can be prevented from happening, and the insulated operation rod head has the advantages of simple and reasonable structure and design, convenient use, low cost and the like.
Description
Technical field
The utility model belongs to electric power system auxiliary equipment technical field, particularly relates to a kind of insulating bar head of installing for the disconnecting link protective cover that insulate.
Background technology
In electric power system, 10kV high-voltage switch is a kind of electric power outdoor equipment, conventionally utilizes two insulators to be suspended in tower bar cross-arm below, is the electric equipments for disjunction, isolate conductive circuit.Because it is minute incompatible effect that reaches disjunction and isolate conductive circuit and show obvious cut-off point that utilizes blade and contact, therefore can not make hermetically sealed equipment.In addition, because it is installed on outdoor, therefore such as bird pest, pollution flashover, corrosion etc. also just becomes the main cause that 10kV high-voltage switch breaks down, especially at northern area, the large-scale bird such as magpie iron wire and mixed modes of taking of tree rod of adopting on disconnecting link are taken nest more, when riding between blade and switch base, iron wire will there is conducting wire ground connection arcing fault, annual March-be multiple season of bird pest by the end of May, 10KV distribution line failure generation in this season number can account for 30% of the whole year, and wherein bird pest fault statistics is 50%.
Often adopt at present the method that installs insulation protecting device on disconnecting link additional to take precautions against this type of fault generation, conventional bird pest protective cover mainly contains two large classes, and one, bird-preventing plate, be arranged on switch base place.Two, silicon rubber bird-proof cover, is arranged on the disconnecting link edge of a knife and blade place.Although above two kinds of bird pest protective covers all have good anti-bird pest effect, but the installation that must have a power failure that shortcoming is bird-preventing plate, silicon rubber bird-proof cover need have a power failure and installs or adopt band electric car by the direct charged installation of maintainer, and there is no special-purpose erecting tools, so these installation methods have limited the timely installation of bird-proof cover.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of insulating bar head of installing for the disconnecting link protective cover that insulate.
In order to achieve the above object, the insulating bar head of installing for the disconnecting link protective cover that insulate that the utility model provides comprises support bar, cross bar, four rake arms and two fork arms; Wherein the lower end of support bar is formed with the external screw thread being connected with transformer station's customary insulation action bars upper end; The middle part of cross bar is fixed on post upper; The rear end standoff distance of four rake arms is fixed on cross bar, and front end is formed with the hook being then bent to form backward downwards; Fork arm is L-shaped, and the rear end standoff distance of two fork arms is fixed on cross bar, and rake arm and fork arm are all positioned at the same side of cross bar.
The length of described rake arm is greater than the length of fork arm.
Stagger each other in described four rake arms and the two fork arms position on cross bar.
Distance in four described rake arms between outermost two rake arms is less than the length of switch base.
The insulating bar head of installing for the disconnecting link protective cover that insulate that the utility model provides can make maintainer when protective cover is installed, effective and live part insulate, can guarantee that repair personnel carries out fitting operation to protector in safe distance, and installing insulating protective cover at any time, to reduce the generation of bird pest fault.In addition, this insulating bar head also has reasonable in design, simple, easy to use, low cost and other advantages.
Accompanying drawing explanation
The insulating bar header structure schematic diagram of installing for the disconnecting link protective cover that insulate that Fig. 1 provides for the utility model.
The insulation disconnecting link protective roof structure schematic diagram that Fig. 2 installs for the insulating bar head that uses the utility model to provide.
Embodiment
The insulating bar head of installing for the disconnecting link protective cover that insulate the utility model being provided below in conjunction with the drawings and specific embodiments is elaborated.
As shown in Figure 1, the insulating bar head of installing for the disconnecting link protective cover that insulate that the utility model provides comprises support bar 10, cross bar 7, four rake arms 8 and two fork arms 9; Wherein the lower end of support bar 10 is formed with the external screw thread being connected with transformer station's customary insulation action bars upper end; The middle part of cross bar 7 is fixed on support bar 10 upper ends; The rear end standoff distance of four rake arms 8 is fixed on cross bar 7, and front end is formed with the hook 11 being then bent to form backward downwards; Fork arm 9 is L-shaped, and the rear end standoff distance of two fork arms 9 is fixed on cross bar 7, and rake arm 8 and fork arm 9 are all positioned at the same side of cross bar 7.
The length of described rake arm 8 is greater than the length of fork arm 9.
Stagger each other in described four rake arms 8 and two fork arms 9 position on cross bar 7.
Distance in four described rake arms 8 between outermost two rake arms 8 is less than the length of switch base.
The insulating bar head using method of installing for the disconnecting link protective cover that insulate now the utility model being provided is described below: when need shown in installation diagram 2 insulation disconnecting link protective cover time, first by maintainer, 4 hook 11 front ends on this insulating mounting bar head are passed down through respectively in 4 erecting tools patchholes 5 of two opening 4 both sides of main body 1 on insulation disconnecting link protective cover, then two erecting tools patchholes 5 of opposite side in main body 1 are inserted on two fork arms 9 insulating mounting bar head from front, afterwards support bar 10 lower ends on insulating mounting bar head are threaded in to the insulating bar upper end that current upkeep operation is conventional, then above to tower bar top, approach disconnecting link place, afterwards by insulating bar, insulating mounting bar head and insulation disconnecting link protective cover are held high, until main body 1 approaches switch base, then 4 hook 11 tops from switch base on insulating mounting bar head are hung over to the inside edge of switch base, two insulators that are connected with this switch base in this process arrange 2 inside, hole by entering into two insulators from two openings 4 in main body 1 respectively, pull back afterwards insulating mounting bar head, two fork arms 9 are exited in two corresponding erecting tools patchholes 5 main body 1, then promote forward insulating mounting bar head, 4 hooks 8 are exited in 4 corresponding erecting tools patchholes 5 main body 1, finally with the front end of hook 8, the edge of opening 4 both sides is stacked together, make edge 3 tightly be centered around insulator lower end outside simultaneously, and whole main body 1 is fitted tightly on switch base surface can complete whole installation process.
