Abstract

The utility model discloses a bare conductor lightning protection gold utensil, this lightning protection gold utensil install on the bare conductor as last electrode, are equipped with lightning arrester body and high voltage electrode as the bottom electrode under the lightning protection gold utensil, the lightning protection gold utensil includes first clamping part and second clamping part, it is as an organic whole that first clamping part and second clamping part pass through the fastener fastening, is equipped with the logical groove that supplies the bare conductor to pass through between first clamping part and second clamping part, be equipped with the convex striking section and the section of burning on the first clamping part. The utility model discloses install additional on the bare conductor behind the lightning protection gold utensil for when the thunder and lightning discharges, even lightning arrester body damages, burn through striking section and the section of burning guide thunder and lightning, avoid the bare conductor to blow, consequently can effectively protect the bare conductor to avoid the burn and break.

Description

A kind of bare conductor lightning protection hardware
Technical field
The utility model relates to lightning arrester, particularly relates to bare conductor lightning arrester, is mainly used in 10kV and exchanges plain conductor transmission line.
Background technology
Plain conductor transmission line has higher requirement to lightning protection, therefore lightning arrester is provided with, it metal profile comprising lightning arrester body, plain conductor insulator and connect lightning arrester body and plain conductor insulator, be provided with high-field electrode at the top of lightning arrester body, between high-field electrode and plain conductor, be provided with air gap.The insulator arc-over that this lightning arrester can prevent thunderbolt circuit from causing is set, reduces the line tripping rate of being struck by lightning and causing.But if during thunder discharge, lightning arrester body damages, and plain conductor is very easily burnt broken string.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of bare conductor lightning protection hardware, when avoiding lightning arrester body to damage, occurs the situation of plain conductor burn broken string.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bare conductor lightning protection hardware, this lightning protection hardware is installed on plain conductor as top electrode, lightning arrester body and high-field electrode is provided with as bottom electrode immediately below lightning protection hardware, described lightning protection hardware comprises the first clamping part and the second clamping part, described first clamping part and the second clamping part are fastened as a whole by securing member, between the first clamping part and the second clamping part, be provided with the groove passed through for plain conductor, described first clamping part is provided with striking section and the section of burning of protrusion.
As preferably, described in the section of burning be provided with two clubfoots, described two clubfoots protrude respectively to the length direction both sides of plain conductor.Make to run under bidirectional power supply mode safer, install more convenient, use more economical.
As preferably, outside described lightning protection hardware, be covered with insulating cover.When thunder and lightning occurs, during the section of burning burning, plain conductor can be protected to avoid blowing.
The utility model after mounted with lightning protection gold utensil, when making thunder discharge, even if lightning arrester body damages, guides thunder and lightning to burn by striking section and the section of burning, avoids plain conductor to blow on plain conductor, therefore can avoid burn broken string by available protecting plain conductor.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of lightning arrester;
Fig. 2 is the structural representation of lightning protection hardware.
Embodiment
As shown in Figure 1, a kind of plain conductor lightning arrester, comprise lightning arrester body 1, plain conductor insulator 2 and connect the metal profile of described lightning arrester body 1 and plain conductor insulator 2, high-field electrode 11 is provided with at the top of lightning arrester body 1, be provided with air gap between described high-field electrode 11 and plain conductor 5, described plain conductor 5 is provided with lightning protection hardware 6 directly over high-field electrode 11.
After thunder discharge; electric arc arc root is transferred on lightning protection hardware 6 by plain conductor 5; the arc root long period of the power frequency short circuiting arc continued is fixed on lightning protection hardware burns; even if lightning arrester body damages; there is provided protection to the position that plain conductor is the most easily burnt, protect plain conductor to avoid burn broken string to greatest extent.
Wherein, lightning arrester body 1 is solid construction.Avoid because respiration brings moisture into interiors of products.
High-field electrode 11 one end extends in plain conductor 5 vertical direction, and shape is linear pattern or arc.Ensure that flashover path still occurs between plain conductor and the high-field electrode of lightning arrester when natural force makes wire swing, strengthen the lightning protection effect of lightning arrester.
Described metal profile is made up of the first supporting section 3 and the second supporting section 4, described first supporting section 3 forms L-type structure by the first horizontal side 31 and the first vertical side 32, described second supporting section 4 forms L-type structure by the second horizontal side 42 and the second vertical side 41, the end of the second horizontal side is provided with elbow 43 vertically downward simultaneously, described first horizontal side is provided with the first holddown groove, the bottom of described lightning arrester body is provided with the first fixed screw 12, described first fixed screw is fixed in the first holddown groove and lightning arrester body and the first horizontal side is fixed, described first vertical side and the second vertical side superimposed, described first vertical side and the second vertical side correspondence are provided with the second holddown groove, through the second fixed screw 33, first vertical side and the second vertical side are fixed together in described second holddown groove, the width both sides of the described first vertical side are provided with rib enclosing in the second vertical side both sides, described second horizontal side is provided with the 3rd holddown groove, the bottom of described plain conductor insulator is provided with the 3rd fixed screw 21, described 3rd fixed screw is fixed in the 3rd holddown groove and plain conductor insulator and the second horizontal side is fixed together.
As shown in Figure 2, described lightning protection hardware 6 comprises the first clamping part and the second clamping part, described first clamping part and the second clamping part are fastened as a whole by securing member (bolt as conventional), the groove 61 passed through for plain conductor is provided with between the first clamping part and the second clamping part, described first clamping part is provided with striking section 62 and the section of burning 63 of protrusion, striking section 62 connects with the section of burning 63, striking section 62 is protruded to plain conductor vertical direction, the section of burning 63 is protruded to plain conductor length direction, therefore the section of burning 63 can be made to have enough thickness and volume, stand repeatedly burning of power frequency arc, even if scaling loss also can freely be changed, easy to maintenance.
Wherein, striking section 62 is that the first clamping part both sides respectively arrange one, and the section of burning 63 is provided with two clubfoots, and described two clubfoots protrude respectively to the length direction both sides of plain conductor 5.Make to run under bidirectional power supply mode safer, install more convenient, use more economical.
In addition, insulating cover is covered with outside described lightning protection hardware 6.When thunder and lightning occurs, during the section of burning burning, plain conductor can be protected to avoid blowing.
