Description
Technical field
The present invention designs transmission line technical field, particularly a kind of cover type outgoing line device.
Background technology
In recent years, along with the development of increase and the technology of transmission of electricity day by day of electricity needs, the UHV transmission line such as 800kV, 1000kV have started to carry out at home building and putting into operation.In the heavier area of gradation for surface pollution, adopt composite insulator to the resistance to pollution flashover ability of raising transmission line, prevent and contain that the generation of pollution flashover accident all can play positive role, and composite insulator has the advantages such as cost is low, non-maintaining, apply in extra-high voltage project, remarkable benefit.
But conventional strain insulator string generally adopts glass insulator (or porcelain insulator), time staff needs to carry out outlet operation, by directly trampling the traditional glass of climbing (or pottery) insulator string, the enterprising line operate of wire can be climbed to from transmission tower.
Ultra high voltage strain insulator-string because composite insulator material resources intensity is poor, fragile, can not bears the climbing of operating personnel and trample after adopting composite insulator.This also just makes in UHV transmission line, and staff in the conventional mode, cannot carry out outlet operation, for the work such as maintenance bring great inconvenience by climbing insulator string.
Above-mentioned technical problem present stage a part have employed composite insulator string the ultra-high-tension power transmission line of electric pressure at below 500kV in also exist.But because the transmission line electric pressure of this part 500kV is lower, so composite insulator length less (generally within 5 meters), so can be solved by the mode of installing overall suspension bridge.But in UHV transmission line, the length of composite insulator string is generally more than 10 meters.Well imagine that the overall suspension bridge installing 10 meters of spans in high-altitude is and loaded down with trivial details, be difficult to realize; Even if realize reluctantly, fail safe and practicality also cannot ensure at all, and high cost.
So present stage lacks a kind of outgoing line device, can realize under the prerequisite not damaging composite insulator string, help staff to complete out line process.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of cover type outgoing line device, realize under the prerequisite not damaging composite insulator string, help staff to complete out line process.
For achieving the above object, the present invention has following technical scheme:
A kind of cover type outgoing line device, described device concrete structure is as follows: described device comprises cover plate, and described cover plate both sides are provided with semi-circular groove, and pedal connects the outer surface of two semi-circular groove.
Described device also comprises: liner, and described liner is semicircle column type, and liner overall diameter is less than the interior diameter of described semi-circular groove, is provided with the groove that shape is mated with insulator umbrella inside liner.
Cross gusset is provided with inside described cover plate.
Described pedal is with downward radian.
Described device also comprises safety belt, and described safety belt one end is fixed in the semi-circular groove of side, and the other end is provided with eye-splice; Then opposite side semi-circular groove is provided with eye-splice interface and described eye-splice snapping.
The material of described cover plate is fiberglass, plastics, aluminium alloy or stainless steel.
The material of described liner is rubber, plastics or foam.
As seen through the above technical solutions, the beneficial effect that the present invention exists is, cover type outgoing line device of the present invention is utilized to cover on composite insulator string, staff can pass through out line process on the pedal of described cover type outgoing line device, avoids trampling and climbing for composite insulator string; In addition, utilize described liner to embed in the semi-circular groove of described device, effectively it is protected, when described cover type outgoing line device covers composite insulator string, utilize liner directly to contact with composite insulator string, the damage of composite insulator string can not be caused.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is cover type outgoing line device structural representation described in the embodiment of the present invention;
Fig. 2 is gasket construction schematic diagram described in the embodiment of the present invention.
Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
With reference to the specific embodiment that Figure 1 shows that cover type outgoing line device of the present invention.Described in the present embodiment, cover type outgoing line device comprises cover plate; The both sides of described cover plate are provided with semi-circular groove, and pedal connects the outer surface of two semi-circular groove; The effect of this semi-circular groove be buckle closure on composite insulator string, namely buckle closure is on adjacent two string composite insulator strings respectively for both sides semi-circular groove, and the distance of two halves circular recess and described adjacent composite insulator string spacing match in actual applications; Utilize pedal to connect two halves circular recesss outside, namely achieve the overall buckle closure of described cover plate on two adjacent composite insulator strings, in the middle of two composite insulator strings, form the effect of similar " bridging "; Multiple described device is utilized to lay one by one along the length direction of composite insulator string in the embodiment of the present invention, current on the passage that staff can be formed at pedal, thus complete out line process by composite insulator string, start to perform appearance operation.
For better protecting composite insulator string, also comprise liner in the present embodiment, with reference to shown in Fig. 2, the structure of described liner is as follows: described liner is half cylindrical structure, for covering the full skirt of composite insulator string.Be provided with groove inside described liner, the size of described groove and shape corresponding with the full skirt of composite insulator string, make liner cover described in meet insulator string after, the full skirt of described insulator string embeds in gasket groove just.
