Description
Technical field:
The utility model relates to a kind of novel device ground connection and fixes anchor ear, belongs to electric power system substation equipment maintenance and repair technical field.
Background technology:
GW4, GW5, GW6, GW7 type isolating switch of 35kV, 110kV, 220kV electric pressure extensively adopts in electric power system, be outdoor anti-fouling type equipment, by length 4500mm, enter ground buried depth 1500mm, ∮ 300mm-∮ 400mm cement pole support [No. 14 basic channel-section steels are located, and distance ground free height is at more than 2500mm.
According to " Substation Electric Equipment operating standard " requirement, before converting equipment installation and operation, reliable surface must be had to establish ground connection with main grounding grid, equipment ground lead-in wire adopts specification to be greater than the zinc-plated band iron of 50mm × 5mm, development length needs reliable fixing when being greater than 1000mm, and the Huang of interval brushing 50mm, green oil paint mark.
More the said equipment, in equipment ground connection work in the past, adopted the zinc-plated band iron of 50mm × 5mm to be connected with main earth mat by equipment along cement pole, be fixed by the typical circular anchor ear of ∮ 300mm-∮ 400mm.This kind be fixedly connected with mode because of typical circular anchor ear with-50 × 5 zinc-plated band iron there is the gap of about 20mm, cannot well coincide, it is unreliable that zinc-plated ground connection band iron is fixed, once there is short trouble in equipment, earth current increases, easily cause ground connection electric discharge fever phenomenon, there is great equipment security of operation hidden danger.If welded with the zinc-plated band iron contact point of 50mm × 5mm by typical circular anchor ear, can ensure that ground connection band iron is firm, but the solder joint very easily corrosion after welding, reduce contact area, reduce its useful life, and do not meet lean substation equipment management expectancy.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of structure simple, it is convenient to install, fixing reliable, long service life, improve the running quality of equipment ground, the novel device ground connection of the security reliability that the equipment of guarantee is powered fixes anchor ear.
The purpose of this utility model can be reached by following measure: a kind of novel device ground connection fixes anchor ear, it comprises circular anchor ear, the both sides of circular anchor ear are provided with anchor ear fixed mount, anchor ear fixed mount is provided with set bolt, it is characterized in that the lower end of circular anchor ear is provided with fixed pan, fixed pan is by set bolt connection device ground connection geometrical clamp.
The utility model can produce following good effect compared with the prior art:
1, the utility model improves on the basis of original anchor ear, do not need to change original fixing anchor ear, input manpower is few, do not increase equipment funds, the equipment ground that just can meet all kinds of high-order converting equipment connects and fixes, reach the object that equipment ground is fixed reliably, high-quality is run, when solving the equipment ground connection of 35kV, 110kV, 220kV electric pressure GW4, GW5, GW6, GW7 type isolating switch and the high-order equipment such as voltage transformer, current transformer, a fixing insecure difficult problem.
2, the equipment ground geometrical clamp by newly installing additional, the contact plane increased with circular anchor ear after improvement is crimped by fastening bolt, can meet-50 × 5 ,-60 × 6 zinc-plated band irons and fix reliable requirement.
3, carry out fastening by set bolt to ground connection band iron, contact is reliable, without the need to welding, reaches the requirement of substation equipment lean.
The utility model with improve existing equipment ground connection fix unreliable for landing point, to increase original circular anchor ear contact plane and anchor ear geometrical clamp for innovative point, when solving that in transformer station, high-order equipment is connected with main grounding grid, a fixing insecure difficult problem, the security reliability that the equipment of guarantee is powered.The utility model structure is simple, and exempt from equipment funds and drop into, it is reliably convenient to install.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment: embodiment of the present utility model is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of novel device ground connection fixes anchor ear (see Fig. 1), it comprises circular anchor ear 4, the both sides of circular anchor ear 4 are provided with anchor ear fixed mount 5, anchor ear fixed mount 5 is provided with set bolt 3, the lower end of circular anchor ear 4 is provided with fixed pan 2, and fixed pan 2 is by set bolt 3 connection device ground connection geometrical clamp 1.
During use, first circular anchor ear 4 anchor ear geometrical clamp 5 is fixed on the circular frameworks such as cement pole by set bolt 3, then equipment ground geometrical clamp 1 is installed on fixed pan 2, then the ground connection band iron set bolt 3 made is fixed in equipment ground geometrical clamp 1 reliably.This ground connection band iron is fixed anchor ear and is fixed with bolt completely, installing/dismounting rapid and convenient, need not electric welding assist.
