Abstract
The utility model relates to an arrester supporter which is widely used for an electricity transmission and transformation system. The utility model comprises an upper clamping plate, a lower clamping plate, an insulating post and a spring clamping pin. The utility model has the advantages that the utility model has electrification checking maintenance, especially when the arrester is damaged by lightning strike, the arrester can be replaced with no need of current failure. The utility model avoids bringing inconvenience life and economic loss to people because of traditional power failure operating method, and is convenient to work for working personnel in the power supply department.
Description
The utility model relates to a kind of lightning protection device, especially relates to a kind of surge arrester support that is widely used in the electric power power transmission and transformation system.
Be struck by lightning for preventing at high-tension bus-bar and high voltage installation, between phase line and zero potential (the earth), settled the organic overcoat metal oxide arrester that two ends are cylindrical conductor usually.This lightning arrester is equal to a resistance when high-voltage line and high voltage installation are struck by lightning be infinitely-great resistance; In case when high-voltage line and high voltage installation are struck by lightning, the resistance of moment is extremely low, the energy that thunder and lightning produces on high-voltage line and high voltage installation can be discharged to the earth, its conducting and blocking state depend on whether thunder and lightning produces thunderbolt to high-voltage line and high voltage installation, thereby prevent that high-voltage line and high voltage installation are not damaged when being struck by lightning.When damaging essential the replacing as lightning arrester because of reasons such as thunderbolts, the power failure of must operating a switch is earlier unclamped lightning arrester two ends and the nut that is fastened on phase line and the zero potential respectively with wrench again, lightning arrester can be taken off.Then change the intact lightning arrester of performance, with the nut screwing clamping of wrench with the lightning arrester two ends, could close a floodgate restores electricity again.Whole process takes a lot of work, time-consuming, and change lightning arrester because of having a power failure and also can bring various troubles and loss to people.
But the purpose of this utility model provides a kind of live line working, the surge arrester support of lightning arrester is changed in installation quickly and easily.
The purpose of this utility model is achieved in that surge arrester support, and it comprises train wheel bridge, lower plate, insulated column, spring detent, and train wheel bridge, lower plate, spring detent are made with metal material, and insulated column is made with insulating material.The fastening insulated column that is equipped with between train wheel bridge one end and lower plate one end, insulated column can traverses, place vertically, tiltedly be placed between train wheel bridge and the lower plate, the fastening in opposite directions respectively spring detent that is equipped with of the other end of train wheel bridge and the other end of lower plate.The height that goes out with the insulated column liner between train wheel bridge and the lower plate should be able to hold whole lightning arrester, and the tensile force of spring detent can embed the metal spring bayonet lock with the cylindrical conductor on the lightning arrester two ends and be advisable.
The utility model is owing to adopt technique scheme, be installed in reservation under the preceding topic of function of use of the lightning arrester on the utility model, also have charged detection maintenance, particularly when the lightning arrester that is struck by lightning damages, needn't have a power failure the advantage of changing lightning arrester just can be installed, avoided because of traditional power failure operational method to life inconvenience and economic loss that people bring, made things convenient for power supply department staff's operation.
Below in conjunction with drawings and Examples embodiment of the present utility model is described in further detail.
Fig. 1 is the front view of the typical structure schematic diagram of the utility model embodiment.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the profile of Figure 1A-A, B-B.
Fig. 4 is installed in working state schematic representation on the utility model for lightning arrester.
With reference to Fig. 1, Fig. 4, the utility model is made up of train wheel bridge 1, lower plate 2, insulated column 3, spring detent 4, the fastening insulated column 3 that is equipped with between one end of train wheel bridge 1 and the end of lower plate 2, the fastening in opposite directions respectively spring detent 4 that is equipped with of the other end of the other end of train wheel bridge 1 and lower plate 2, the cylindrical conductor 6 on lightning arrester 5 two ends embeds in the spring detent 4.
Embodiment: with reference to Fig. 1, Fig. 4, an end of train wheel bridge of the present utility model, lower plate is fastenedly connected phase line and zero potential respectively, again the cylindrical conductor on the lightning arrester two ends is embedded spring detent, just can prevent that high-voltage line and high voltage installation are struck by lightning.In case it is former thereby damage when needing to change because of thunderbolt etc. to be installed on the utility model lightning arrester, can be under situation about not having a power failure, go out to embed the lightning arrester that damages in the spring detent with a special-purpose hook rod hook, change the intact lightning arrester of performance, just can reach the purpose of the present utility model.
Claims (1)
- Surge arrester support is characterized in that: the fastening insulated column that is equipped with between an end of train wheel bridge and the end of lower plate, the fastening in opposite directions respectively spring detent that is equipped with of the other end of train wheel bridge and the other end of lower plate.
