Description
Technical field
The present invention relates to a kind of live line work insulating shading tool, a kind of charged cut-off straight line pole hard group
Close mask.
Background technology
Live line work insulating cover be livewire work personnel and adjacent phase electrical body, grounding body safe distance deficiency time protect
The important means of barrier personal safety.At present, during distribution network live line work, the insulation shading tool of use is general mostly
Soft instrument (insulated target, rubber tube etc.).Soft insulating instrument is the most easy to wear, service life is short for these, cost is high, more important
Be for covering the connection of shaft tower equipment, edges and corners time, owing to soft insulating instrument does not matches that therewith, it tends to be difficult to cover
Tight or dismounting difficulty is relatively big, add the security risk of operating personnel.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, and provide one to be easily installed, dismantle, safety
High charged cut-off straight line pole hard combined shielding cover.
One is charged cut-offs straight line pole hard combined shielding cover, includes double cross arm shielding covers and two strain insulators
Porcelain vase and needle porcelain bottle foot mask,
Described double cross arm shielding covers are a kind of channel-shaped insulator snapping in double cross-arm；
Described tension-resistant porcelain bottle and needle porcelain bottle foot mask include the insulation channel-shaped body of a section, the bottom surface of channel-shaped body with
One side extends along the side in channel-shaped body length direction, and bottom surface simultaneously free end also along bottom surface stretches out, at groove
The open slot of the length direction extension along channel-shaped body, leaning at open slot it is provided with on the length direction extension of shape body bottom surface
Being provided with the draw-in groove that bottom land and groove dual-side along open slot the most uprightly extend at nearly bottom, described draw-in groove is perpendicular to the end
Face, draw-in groove and open slot can snap in needle porcelain bottle porcelain group bottom, and channel-shaped body then should cover on tension-resistant porcelain bottle, the strain insulator porcelain of two
Bottle and needle porcelain bottle foot mask are symmetrical structure, and one of them tension-resistant porcelain bottle and needle porcelain bottle foot mask have draw-in groove
That one end more than the draw-in groove end of another tension-resistant porcelain bottle and needle porcelain bottle foot mask to be suitable for that little tension-resistant porcelain bottle
And needle porcelain bottle foot mask can snap in another tension-resistant porcelain bottle and needle porcelain bottle foot mask, the degree of depth sum of two draw-in grooves should
More than diameter 10cm more than or equal to needle porcelain bottle foot.
The charged straight line pole hard combined shielding cover that cut-offs of the present invention, in use, by double cross arm shielding covers from upper and
Lower cover on cross-arm, then by the tension-resistant porcelain bottle of two and needle porcelain bottle foot mask from both sides and top-down cover to strain insulator
Then push away from both sides toward middle needle porcelain bottle foot direction on porcelain vase, until tension-resistant porcelain bottle and the draw-in groove of needle porcelain bottle foot mask
Needle porcelain bottle foot is encased, it is ensured that the intersection of two tension-resistant porcelain bottles and needle porcelain bottle foot mask draw-in groove is more than 10 cm, from
And realize covering of tension-resistant porcelain bottle, cross-arm and needle porcelain bottle foot, to realize livewire work.The free end of bottom surface refers to that bottom surface does not has
That one end connected with side.
The side of the channel-shaped insulator of described double cross arm shielding covers is towards the tilted hypotenuse of channel-shaped insulator.
Use this hypotenuse structure, it is simple to be stuck on cross-arm by double cross arm shielding covers, prevent unexpected coming off.
Described double cross arm shielding covers use high-density polyethylene material warp with tension-resistant porcelain bottle and needle porcelain bottle foot mask
Softening processes.
In sum, the present invention following advantage compared to existing technology:
The charged of the present invention cut-offs straight line pole hard combined shielding cover, is applicable to triangle, level and vertical row
The list of row returns distribution line straight line pole.Also the equipment primary shield on operation shaft tower can be put in place, simple to operate, dismounting side
Just, cut-offfing the straight line pole operation used time than originally shortening nearly 30%, work efficiency is greatly improved.Use this mode of covering can avoid operation
Personnel's hand in insulation masking process acts directly between electrical body and grounding body, solves not enough the asking of safe distance
Topic, fulfils assignment more easily, improves security reliability.The charged of the present invention is used to cut-off the combination screening of straight line pole hard
Covering cover, average man-hours are than using insulated target etc. to reduce 30%, and the charged straight line pole hard combined shielding cover that cut-offs of the present invention sets
Count reasonable, easy for installation, security performance is more excellent, and is applicable to various lines, solves the problem that field operation runs into,
Improve work efficiency, reduce production cost.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in more detail.
Embodiment 1
A kind of charged cut-offs straight line pole hard combined shielding cover, include double cross arm shielding covers 1 and two resistance to
Open porcelain vase and needle porcelain bottle foot mask 2,
Described double cross arm shielding covers are a kind of channel-shaped insulator snapping in double cross-arm, described double cross arm shielding covers
The side of channel-shaped insulator is towards the tilted hypotenuse of channel-shaped insulator.
Described tension-resistant porcelain bottle and needle porcelain bottle foot mask include the insulation channel-shaped body 21 of a section, the bottom surface of channel-shaped body
