Abstract
The utility model relates to a protecting device for post insulator, which comprises a protective jacket packaged under the insulator. The protective jacket is fixed with the insulator base through a holder, and the upper end of the protective jacket is packaged with an ascent skirt. In the structure design, the tip-over character of the insulator when breaking is taken into consideration, therefore the force of each part is adjusted and the key point is controlled to ensure that the insulator can be effectively constrained from any direction falling. Besides, the need of electrical insulation is taken into consideration, therefore after adding an indented internal skirt, a ascent skirt is added at the installation top to ensure the insulating ability. Furthermore, the need to proof water is taken into consideration because the adding of the ascent skirt not only increases the ascent distance but also serves as an umbrella as well as a parasol.

Embodiment
The utility model global design is that protective sleeve 3 adopts two half block symmetrical structure bodies that porcelain insulator 1 is embraced, and takes certain measure to take root simultaneously, when insulator 1 falls, supports insulator 1 unlikely falling.The utility model mainly is divided into two partly, and a part guarantees to have enough mechanical strengths and electric property for the insulation 1 of embracing insulator is a protective sleeve 3 partly; Another part root part of making a living, the fixed mount that promptly connects insulator 1 pedestal and protective sleeve 3 guarantee to have the insulator and the base-separation of enough power control fractures when falling.
As shown in Figure 1, consider the needs of electric insulation and the needs that mechanical force is transmitted, the profile that the utility model protective sleeve 3 internal layer curves carry out particular design and insulator 1 matches.
For preventing that outside moisture from entering the gap of insulator and protective device, the while does not influence stressed again, adopts the flexible silicon rubber cushion to fill between the gap, adds insulation silica gel between rubber cushion, porcelain patticoat, the protective device.
As shown in Figure 2, in order further to improve insulation property and rainproof, install creeping-increasing skirt 2 additional at the top, this moment, creep distance can extend greatly, and the utility model creeping-increasing skirt 2 and protective sleeve 3 can be made into one.
Under the preceding topic that guarantees electrical insulation capability, for ease of processing, simplify configuration design as far as possible, configuration design is become smooth surface, can satisfy the requirement of insulation property fully at fine weather, when big rainy day, although the sticking water of material, but smooth outer surface can form current because rainwater is too big, causes short circuit up and down.Need to install additional rain-proof structure for this reason, the top creeping-increasing skirt is strengthened, along having finished rainproof task, increased creep distance simultaneously again as the room.
The analysis of the stressed image of protective device can be described as two hands, holds the upper half part of fracture back insulator 1 on the other hand, and another pulls the bearing pedestal of insulator 1 root.Last hand also will be held tightly except insulator will being held, and not so held the pin head and also can contact to earth, and causes shorted to earth.Need the two halves structure to combine securely based on such consideration top structural defence cover 3, i.e. head design.The bottom will conveniently connect together securely with bearing pedestal, i.e. foot designs.As shown in Figure 6, fixed mount is made of 4 links 5 of fixedlying connected with reinforcing ring 4, and the other end of link 5 is fixedlyed connected with the insulator bearing pedestal by adjustment screw 6, arm-tie 7.
When falling after the fracture of insulator 1 root; vertical direction meeting run-off the straight; the side force of a level is arranged protective device at top; this side force just is the gravitation (maximum 1.8KN) of electric wire; when the inclination angle occurs; have the horizontal component of the gravity drift angle of an insulator, simultaneously the gravitation of electric wire can decline to a great extent because of the displacement at top (electric wire hang down arc angle when being 0 ° lead gravitation for infinitely great).The opening of incision position can have a lifting force that makes progress to protective device, and this lifting force is very big, can make protective device head and pin separate to deviate from and loses efficacy.
Head design has an impulsive force in the time of need considering to rupture, this impact force action can cause the secondary breakdown of insulator in the part, and protection was lost efficacy.Therefore, when selection, select certain flexible material for use, can alleviate impulsive force.Consider from the angle of dispersive stress in addition, design a plurality of teeth, climb in difference and apply counter-force on the skirt simultaneously, stress can be reduced to minimum like this, and impulsive force has obtained effectively dissolving, as shown in Figure 3.
3 two half blocks of protective sleeve can be separately under the effect of insulator 1 lifting force and side direction horizontal force; protection was lost efficacy; therefore two half blocks must tightly connect together; enough intensity is arranged; consider the requirement of profile again; with the requirement of insulation property, adopt two countersunk head screws two half blocks to be linked together tightly by screw hole 8.For easy to assembly, hexagonal in screw adopts.
As shown in Figure 4; two half block composition surfaces of protective sleeve 3 are that seam 10 is under the effect of side force and lifting force; the relative changing of the relative positions of meeting generating plane; for preventing this changing of the relative positions; on surface design, add square pinning piece 9; when the changing of the relative positions takes place when, can can't finish because of the pinning effect of pinning piece, be a complete integral body thereby make whole head.Not destroying of head loop configuration is the preceding topic condition that protective device provides effective protection.(if in the mechanical test process, do not find the serious changing of the relative positions, can not add the pinning piece)
As shown in Figure 4, protective sleeve 3 head two parts generally can not opened after connecting by four bolts; but the bottom will connect root; lifting surface area is little, stressed bigger simultaneously, as shown in Figure 5; so for safety; further install retainer ring additional, make two parts more firm, guarantee at any time can not separate; adopt the mode of fluting embedding reinforcing ring 4 on protective sleeve 3 to connect simultaneously, more make retainer ring can not deviate from equiprobable situation.
Root is stressed main position, and full steel structure is adopted in fixed mount design, and promptly link 5 welds together with reinforcing ring 4 retainer rings of protective sleeve 3, and reinforcing ring 4 bottoms withstand on around coiling with the orchid of bearing pedestal to the below, i.e. hook.The height difference of insulator root.Protective device is for adapting to the insulator of different height, and the bottom adds an adjustment screw 6 of adjusting height, adjusts screw at the insulator of root differing heights and holds out against the below.Insulator 1 has different directions when falling, at different directions, the hook of four symmetries of design is a link 5, and link 5 adopts four L section steel bar.The moment of flexure of root can make hook outwards open, and for this reason, designing four braces is arm-tie 7, and four hooks are fused.The ring flange cover of ining succession like this, the insulator upper part that cover is ined succession and had no progeny has formed a continuous integral body.
