The method utilizes a hard combined shielding cover for an electrified on-off straight pole to shield a tension-resisting porcelain bottle, a crosspiece and a pin type porcelain bottle foot which have insufficient safety distances during operation, is convenient to install and excellent in safety performance, is suitable for multiple types of lines, solves the problems encountered in field operation, improves the work efficiency and reduces the production cost.
Description
Technical field
The present invention relates to a kind of live line working method, particularly a kind of charged straight line pole operation insulation masking methods that cut-offs.
Background technology
It is the important means that safe distance at live line working personnel and adjacent phase electrified body, earth electrode guarantees personal safety when not enough that live line work insulating covers.At present, in the distribution network live line work process, the insulation shading tool of use is general soft instrument (insulated target, rubber tube etc.) mostly.These soft insulating instruments not only easy to wear, useful life is short, cost is high, while the more important thing is connection for covering shaft tower equipment, edges and corners, because the soft insulating instrument is not complementary with it, often be difficult to cover tight or the dismounting difficulty is larger, increased operating personnel's security risk.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and a kind of installation, dismounting, safe charged charged straight line pole operation insulation masking methods that cut-offs that straight line pole is used that cut-offs be convenient to is provided.
A kind of charged insulation masking methods for straight line pole that cut-offs, a kind of charged straight line pole hard combined shielding cover that cut-offs is provided, the described charged straight line pole that cut-offs includes two cross arm shielding covers and two tension-resistant porcelain bottles and needle porcelain bottle pin mask with hard combined shielding cover
Described pair of cross arm shielding cover is a kind of groove shape insulator that snaps in two cross-arms;
Described tension-resistant porcelain bottle and needle porcelain bottle pin mask include the insulation tank shape body of a section, extend along a side of groove shape body length direction the bottom surface of groove shape body and a side, and bottom surface also stretches out along the free end of bottom surface simultaneously, be provided with the open slot extended along the length direction of groove shape body on the length direction extension of groove shape body bottom surface, place, close bottom at open slot is provided with the draw-in groove upwards uprightly extended along bottom land and the groove dual-side of open slot, described draw-in groove is perpendicular to bottom surface, draw-in groove and open slot can snap in needle porcelain bottle porcelain group bottom, groove shape body should cover on tension-resistant porcelain bottle, the tension-resistant porcelain bottle of two and needle porcelain bottle pin mask are symmetrical structure, and the draw-in groove end that end that one of them tension-resistant porcelain bottle and needle porcelain bottle pin mask have a draw-in groove is greater than another tension-resistant porcelain bottle and needle porcelain bottle pin mask can snap in another tension-resistant porcelain bottle and needle porcelain bottle pin mask to be applicable to that little tension-resistant porcelain bottle and needle porcelain bottle pin mask, more than the degree of depth sum of two draw-in grooves should be more than or equal to the diameter 10cm of needle porcelain bottle pin, by two cross arm shielding covers, cover on cross-arm from top to bottom, then by the tension-resistant porcelain bottle of two and needle porcelain bottle pin mask from both sides and top-down cover to tension-resistant porcelain bottle, then from both sides toward middle needle porcelain bottle pin direction, push away, until the draw-in groove of tension-resistant porcelain bottle and needle porcelain bottle pin mask encases the needle porcelain bottle pin, the intersection that simultaneously guarantees two tension-resistant porcelain bottles and needle porcelain bottle pin mask draw-in groove is greater than 10 cm, thereby realize tension-resistant porcelain bottle, covering of cross-arm and needle porcelain bottle pin.
The charged straight line pole operation insulation masking methods that cut-offs of the present invention, adopted a kind of novel charged straight line pole hard combined shielding cover that cut-offs, in use, by two cross arm shielding covers, cover on cross-arm from top to bottom, then by the tension-resistant porcelain bottle of two and needle porcelain bottle pin mask from both sides and top-down cover to tension-resistant porcelain bottle, then from both sides toward middle needle porcelain bottle pin direction, push away, until the draw-in groove of tension-resistant porcelain bottle and needle porcelain bottle pin mask encases the needle porcelain bottle pin, the intersection that guarantees two tension-resistant porcelain bottles and needle porcelain bottle pin mask draw-in groove is greater than 10 cm, thereby realize tension-resistant porcelain bottle, covering of cross-arm and needle porcelain bottle pin, to realize live line working.The free end of bottom surface refers to that bottom surface does not have that end joined with side.
One side of the groove shape insulator of described pair of cross arm shielding cover is towards the tilted hypotenuse of groove shape insulator.
Adopt this hypotenuse structure, be convenient to two cross arm shielding covers are stuck on cross-arm, prevent accidental.
The described pair of cross arm shielding cover and tension-resistant porcelain bottle and needle porcelain bottle pin mask adopt high-density polyethylene material to process through softening.
In sum, the present invention's following advantage compared to existing technology:
The charged straight line pole operation insulation masking methods that cut-offs of the present invention, the charged straight line pole hard combined shielding cover that cut-offs of employing, return the distribution line straight line pole applicable to the list of triangle, level and vertical arrangement.Also the equipment primary shield on the operation shaft tower can be put in place, simple to operate, easy accessibility, cut-offfing the straight line pole operation used time shortens closely 30% than original, and work efficiency improves greatly.Adopt this mode of covering can avoid operating personnel's hand in the insulation masking process to act directly between electrified body and earth electrode, solved the problem of safe distance deficiency, fulfil assignment more easily, improve security reliability.Adopt the charged straight line pole hard combined shielding cover that cut-offs of the present invention, average man-hours ratio employing insulated target etc. will reduce 30%, of the present invention charged cut-off straight line pole with hard combined shielding cover reasonable in design, easy for installation, security performance is better, and be applicable to various lines, solved the problem that field operation runs into, improve operating efficiency, reduced production cost.
