Specific embodiment
It in order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There are attached drawing and technical solution needed in technology description to be briefly described, it should be apparent that, it is attached in describing below
Figure is only some embodiments of the present invention, for those of ordinary skill in the art, before not making the creative labor
It puts, can also be obtained according to these attached drawings other attached drawings.
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, including sequentially connected protective case 100, insulator body 200, connector sleeve 300, bottom from top to bottom
Seat 400, the 100 across shape of protective case, 100 horizontal direction of protective case are equipped with through hole 110, and vertical direction is equipped with blind
The hole 120 and blind hole 120 is opening down；The insulator body 200 includes full skirt insulation sleeve 210 and is arranged in described
Plug 220 inside full skirt insulation sleeve 210, the top of the plug 220 are threadedly coupled with the protective case 100；The connection
It covers 300 both ends and is equipped with thread groove 310, the thread groove 310 and the plug on 300 top of connector sleeve in the axial direction
220 bottoms are threadedly coupled；The pedestal 400 is in stud shape, the pedestal 400 and the screw thread of 300 bottom of connector sleeve
Slot 310 is threadedly coupled, and 400 middle of pedestal is equipped with laterally disposed metal leg 600, and the metal leg 600 is through described
Pedestal 400；The side wall of 100 bottom of protective case is equipped with and stretches into hole 111, the top of the plug 220 be equipped with screw hole 221 and
The screw hole 121 is horizontally disposed, and the axis of the screw hole 121 is overlapped with the axis for stretching into hole 111, the insulator body
200 one sides are equipped with starting rod 500, and described 500 one end of starting rod is stretched into hole 111 and matched somebody with somebody with 221 screw thread of screw hole through described
It closes, the other end is equipped with metal cap 510, and the metal cap 510 has close to the metal leg 600 and between the metal leg 600
Gap, clearance distance is between 8mm~25mm.
A kind of Novel lightning-proof insulator provided by the invention, when being struck by lightning and obtain overvoltage, can draw from described
It discharges between the metal leg 600 on the metal cap 510 and the pedestal 400 on arc stick 500, makes afterflow power frequency arc
It is moved on the starting rod 500 and burns, so as to protect insulated conductor injury-free；Simultaneously because using modular construction, peace
Assembly and disassembly are convenient, easy to repair or replacement insulator, and also can preferably protect insulator using the protective case 100,
Other rainwater filths are avoided from junction into generation pollution flashover is contacted with insulator, so as to improve the use longevity of insulator
Life.
More specifically, when needing replacing the insulator body 200, first the starting rod 500 can be stretched into from described
Hole 111 is taken out, and is then spun out 220 bottom of the plug of the insulator body 200 from the connector sleeve 300, most
220 top of the plug of the insulator body 200 is spun out from the protective case 100 afterwards, it is possible to remove described
Insulator body 200.
Further, the protective case 100 and the connector sleeve 300 are made of insulating materials, such as rubber.
Further, the internal diameter of the through hole 120 is bigger 1.5mm~2.0mm than the diameter of high-voltage line, should cause high-voltage line
It by the through hole 120, can ensure the leakproofness of high-voltage line and the through hole 120 again.If high-voltage line and the through hole 120
Gap it is excessive, rainwater can be entered by the gap of high-voltage line and the through hole 120 to be contacted with the insulator body 200, from
And the insulating effect of the insulator body 200 is influenced, endanger the safety of entire power grid.
Further, the distance between thread groove 310 described in 300 both ends of connector sleeve is more than 2cm, the connector sleeve
300 can block electric current to pass to the pedestal 400 from the plug 220, so as to which electric current can only be transmitted to the starting rod 500.
And the distance that the connector sleeve 300 separates the plug 220 and the pedestal 400 is bigger, electric current is just less susceptible to pass through institute
State connector sleeve 300.
Further, 500 outer wall of starting rod is equipped with insulation sleeve 700, except 500 end of thread of starting rod and institute
It states at metal cap 510, described its elsewhere of 500 outer wall of starting rod is equipped with insulation sleeve 700 so that is transmitted to the starting rod 500
Electric current electric discharge can be concentrated at the metal cap 510, avoid electric current do not concentrate and caused by discharge effect it is low.
Further, described stretch into is equipped with sealing ring 800 in hole 121, avoids rainwater or other filths are drawn from described
Arc stick 500, into the protective case 100, effectively prevents rainwater and the insulator sheet with the gap for stretching into hole 121
Pollution flashover occurs for the contact of body 200, so as to reduce the insulating effect of the insulator body 100.
Further, the sealing ring 800 is equipped with circular draw ring 810, when need replacing the insulator body 100 or
During the starting rod 500, the circular draw ring 810 can be firmly pullled, so as to which the sealing ring 800 is stretched into hole from described
111 pull out.The circle draw ring 810 is so that the dismounting sealing ring 810 is more convenient.
Further, 100 both sides of protective case are set at top there are two mounting ear 112, two mounting ears
112 are oppositely arranged, and can be fixed on by two mounting ears 112 on grid equipment, it is therefore prevented that the protective case 100 is in height
It is moved on crimping, two be oppositely arranged the mounting ear 112 can guarantee the balance of insulator installation.
The present invention is described with reference to the preferred embodiments, and those skilled in the art know, is not departing from the present invention's
In the case of spirit and scope, various changes or equivalence replacement can be carried out to these features and embodiment.The present invention is from this
The limitation of specific embodiment disclosed in place, other embodiments fallen into claims hereof belong to protection of the present invention
Scope.
