It is an object of the invention to overcome prior art defect, provide it is a kind of prevent from toppling over the Lightning-Rod Protection Disign In Substations to fall,
By installing a kind of packaging type falling proof device outside ring flange, it can effectively avoid flange plate bolt fatigue failure upper back and keep away
Thunder needle needle body and lower base or ground terminal are detached from ring flange, can be prevented toppling over for lightning rod from falling, be avoided flange valve snail
Lightning rod, which topples over to fall, after bolt failure smashes nearby device and causes quadratic loss.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of Lightning-Rod Protection Disign In Substations of packaging type fall arrest, including lightning rod needle body, needle pedestal/ground terminal and packaging type are prevented
Drop device, lightning rod needle body and needle pedestal/ground terminal end are provided with ring flange, and two ring flanges are bolted
To fix lightning rod needle body and needle pedestal/ground terminal；Packaging type falling proof device surround and is wrapped in outside ring flange, for limiting
Make two ring flange separation.
Preferably, packaging type falling proof device section is U-shaped, C-shaped or V-arrangement.
Preferably, packaging type falling proof device is the tire-like structure that formation is circumferentially connected by muti-piece curved slot arrangement.
Preferably, packaging type falling proof device includes two pieces, three pieces or four pieces curved slot arrangements.
Preferably, the end of every piece of slot structure is provided with the square plate with bolt hole, and adjacent slot structure is passed through using bolt
Square plate with bolt hole is fixed.
Preferably, packaging type falling proof device radially with lightning rod needle body, needle pedestal/there are gaps for ground terminal, and not
It is connected directly.
Preferably, multiple stiffeners for fixed flange and lightning rod needle body are disposed on ring flange, packaging type is anti-
Drop device is wrapped in stiffener periphery.
Preferably, stiffener includes two right-angle sides, and right-angle side and ring flange weld, another right-angle side and lightning-arrest
Needle needle body or needle pedestal/ground terminal welding.
Compared with prior art, the present invention has the following advantages that：
Lightning-Rod Protection Disign In Substations of the invention, lightning rod needle body outside ring flange by installing a kind of packaging type fall arrest dress
It sets, packaging type falling proof device can effectively limit two ring flange separation, can effectively keep away around being wrapped in outside ring flange
Exempt from flange plate bolt fatigue failure upper back lightning rod needle body and lower base or ground terminal is detached from ring flange, can prevent from keeping away
Toppling over for thunder needle is fallen.Structure is simple, easy to use, can avoid toppling over for lightning rod and falls, lightning rod is avoided to topple over to fall and pound
Bad nearby device causes quadratic loss.

Specific embodiment
Illustrate that the present invention implements the technological means realized, creation characteristic in order to clearer, with reference to the accompanying drawing to this hair
It is bright to be further elaborated.
Referring to shown in FIG. 1 to FIG. 2, a kind of Lightning-Rod Protection Disign In Substations of packaging type fall arrest, the arrester device includes keeping away
Thunder needle needle body 1, needle pedestal/ground terminal 2；Lightning rod needle body 1 is attached with ground terminal by ring flange 3 and the first bolt 5, is had
Body is lightning rod needle body 1 and needle pedestal/ground terminal 2 end is respectively provided with a ring flange 3, and two ring flanges 3 pass through the first spiral shell
Bolt 5 is fixedly connected.In order to reinforce protecting, each ring flange 3 be equipped with stiffener 4, two right-angle sides of stiffener 4 respectively with method
Two right-angle sides of blue disk 3, the fixation of lightning rod needle body 1 or stiffener 4 are solid with ring flange 3, needle pedestal/ground terminal 2 respectively
It is fixed.
Particularly, packaging type falling proof device 6,6 top of packaging type falling proof device and lightning rod are equipped with outside ring flange 3
There are certain intervals for needle body 1, lower part and needle pedestal/ground terminal 2, are not connected directly.The substation of packaging type fall arrest is lightning-arrest
Needle includes lightning rod needle body 1 and needle pedestal/ground terminal 2, and the two is attached by ring flange, and is set outside ring flange connection
Set packaging type falling proof device.
Referring to shown in Fig. 3~Fig. 6, the packaging type falling proof device 6 is located on the outside of ring flange, is divided into left and right two
Half, left and right two halves end is provided with the square plate 7 in strap bolt hole, and left and right two halves are connected by the second bolt 8.Packaging type fall arrest
The section of device is the shape after " u "-shaped is rotated by 90 °, and size is slightly larger than ring flange 3 and the outsourcing profile of stiffener 4.Packaging type
Radially there are certain intervals with lightning rod needle body 1, needle pedestal or ground terminal 2 for fall arrest attachment device 6, are not connected directly.
