Abstract
The utility model relates to an electric insulator cover, structurally comprising two semicircular cover bodies which are butt-jointed and combined, wherein a connecting piece is arranged at the butt-jointed position of the cover bodies; and the central positions of the cover bodies are provided with gaps. The electric insulator cover can be combined and connected to the top end of an insulator string so as to form a covering body, therefore, accumulated snow on an umbrella skirt of an upper-layer insulator is avoided, further continuous ice columns from top to bottom are prevented from being formed on the insulator string, and necessary insulativity of the insulator string is guaranteed. In the electric insulator cover, the installation is simple, the use is safe and convenient, and the line fault caused by a reason that the accumulated snow on the insulator string of a bracket of high-voltage power supply lines forms ice is solved thoroughly, so that the power supply safety is improved.
Description
Technical field
The utility model relates to the safety attachment on a kind of high voltage supply circuit, specifically a kind of electric insulator cover cap.
Background technology
Insulator is the customary insulation isolating device that prevents on the high voltage supply circuit that power circuit is short-circuited, also must the bunchiness setting on the support of high-voltage electric power circuit.Because the insulator on the electric power support all is vertical bunchiness setting, and northerly cold ice and snow can be iced scraper-trough conveyer and form because of freezing behind the snow melting on this insulator string in winter.And in a single day this ice scraper-trough conveyer connects into post up and down, will cause the failure of insulation of insulator string, and the initiation support is charged or the short trouble of generation power circuit.At present, for the ice scraper-trough conveyer on the insulator string, be mostly to adopt the artificial mode that goes up the electric power support and use the instrument that beats to smash of climbing to handle.But because the staff of each supply station is limited, the power high voltage circuit of being administered has and prolongs more than continuous tens of kilometer, the distribution of electric power support is also very extensive, therefore, and the simple mode that relies on artificial elimination, the one, workload is huge and very arduous, and is also dangerous; The 2nd, the work efficiency of this mode is low, can not accomplish timely cleaning, therefore, is difficult to avoid effectively the generation of supply line's short trouble.
Summary of the invention
The purpose of this utility model just provides a kind of electric insulator cover cap, becomes to ice the line fault that is caused with the insulator string on the support of thorough solution high voltage supply circuit because of accumulated snow.
The utility model is achieved in that a kind of electric insulator cover cap, comprises the semicircle lids of two butt joint assembly groups, is provided with brace at the joint of described lid, has breach at the circle centre position of described lid.
Two semicircular lids dock mutually, connect to form the screen body of a circle by cross-under securing member on brace.Its assembling is connected to the top of the insulator string on the support of high voltage supply circuit, the breach of lid circle centre position can pass for the wiring of insulator string.Like this, just the top of each insulator string on the electric power support has formed a screen body, thereby avoided the existence of the accumulated snow on the insulator full skirt of upper strata, also just avoided on insulator string, forming the continuous icicle from the top to the bottom thus, guaranteed the insulating properties of necessity of insulator string.
Described lid is a sphere shape.So just can form the screen body of a similar umbrella, improve occlusion effect the some insulators in upper strata of insulator string.
The crimping that turns in the edge of described lid is provided with.Crimping on two lids can so just can prevent the generation of the point discharge phenomenon of lid edge effectively to being connected into the grading ring of a closure after the assembly group, improved the safety in utilization of electric insulator cover cap thus.
The utility model is installed simple, and is safe in utilization, convenient, thoroughly solved insulator string on the support of high voltage supply circuit because of the line fault that accumulated snow becomes ice to be caused, and improved the fail safe of power supply.

Embodiment
This electric insulator cover cap comprises two semicircle lid 1(Fig. 2), two lids 1 can dock pieces together the screen body of forming a circle.As shown in Figure 1, semicircular lid 1 is sphere shape (also can be planar shaped or the taper shape that certain taper is arranged etc.).Outer surface in the butt joint edge of lid 1 is provided with brace 2, is shaped on some securing member jack holes on brace 2.After brace 2 on two lids is involutory, with the securing member cross-under fastening after, two lids 1 can be fixed together, form the electric insulator cover cap of a umbrella.The crimping 3 that turns in the edge of the outboard end of lid 1 is provided with is to form the grading ring that prevents point discharge after the assembly group.
Among Fig. 2, have semicircular breach at the circle centre position of lid 1.
Claims (3)
1. an electric insulator cover cap is characterized in that, comprises the semicircle lids (1) of two butt joint assembly groups, is provided with brace (2) at the joint of described lid (1), has breach at the circle centre position of described lid (1).
2. electric insulator cover cap according to claim 1 is characterized in that, described lid (1) is a sphere shape.
