Abstract
The utility model relates to a lightning arrester, which mainly solves the problems that the existing lightning arrester is easily damaged due to low strength. The lightning arrester comprises a flange (1) and is characterized in that an insulation mandrel (2) is fixed at the center of the flange (1), a plurality of zinc oxide resistance plates (3) which are laminated together are sleeved outside the insulation mandrel (2), a silicon rubber umbrella sleeve (4) is poured outside the zinc oxide resistance plates, the top of each zinc oxide resistance plate is electrically connected with a cable (5), and the end of each cable (5) is provided with a junction terminal (6). The insulation mandrel is used as a central support, so that the lightning arrester has high strength and is hardly damaged.
Description
Technical field
The utility model relates to a kind of lightning protection electric armour clamp, is specifically related to a kind of lightning arrester.
Background technology
In the electric power transfer process, for exempting from lightning surge, high-tension overhead line attacks, generally connect lightning arrester at high-tension cable.When lightning surge entered cable line, lightning arrester at first discharged, and with the introducing the earth of lightning current through good conductor safety, utilized earthing device to make the lightning voltage amplitude limitation below certain level, and transmission line is protected.The lightning arrester lower end is fixed on the cross-arm of pylon by flange, the lightning arrester upper end utilizes parallel groove clamp to be electrically connected by cable and high-tension line, be provided with zinc oxide resistance sheet in the lightning arrester, utilize the desirable voltage-current characteristic of zinc oxide valve plate, its resistance is nonlinear change, namely when big electric current, be low resistance characteristic, limited the voltage on the lightning arrester, under normal power-frequency voltage, be high-ohmic, when overvoltage value reaches specified action voltage, lightning arrester moves immediately, flows through electric charge, the over-voltage amplitude; After magnitude of voltage was normal, lightning arrester restored to the original state rapidly again, to guarantee system's normal power supply.Because lightning arrester is installed in the open air, has low, the flimsy defective of intensity.
The utility model content
In order to overcome low, the flimsy deficiency of existing lightning arrester intensity, the utility model provides a kind of lightning arrester, and this lightning arrester adopts insulation mandrel as central supported, has intensity height, non-damageable characteristics.
The technical scheme that the utility model adopts is: a kind of lightning arrester, comprise flange, fixedly there is insulation mandrel the center of flange, insulation mandrel is with a plurality of zinc oxide resistance sheets that are superimposed outward, zinc oxide resistance sheet is cast with the silicon rubber umbrella cover outward, the top of zinc oxide resistance sheet is electrically connected cable, and cable ends is provided with binding post.
Described flange is triangle.
The beneficial effects of the utility model are: owing to take technique scheme, increased insulation mandrel, has higher intensity after flange and cross-arm are fixing, insulation mandrel effectively supports zinc oxide resistance sheet, avoid its distortion or crooked, when being connected by parallel groove clamp between the long service life, binding post and high-tension cable, easy to connect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of flange 1 among Fig. 1.
1-flange among the figure, 2-insulation mandrel, 3-zinc oxide resistance sheet, 4-silicon rubber umbrella cover, 5-cable, 6-binding post.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As Fig. 1 in conjunction with shown in Figure 2, a kind of lightning arrester, comprise flange 1, fixedly there is insulation mandrel 2 center of flange 1, be with a plurality of zinc oxide resistance sheets that are superimposed 3 outside the insulation mandrel 2, zinc oxide resistance sheet is cast with silicon rubber umbrella cover 4 outward, and the top of zinc oxide resistance sheet is electrically connected cable 5, and the termination of cable 5 is provided with binding post 6.Owing to take technique scheme, increased insulation mandrel 2, has higher intensity after flange 1 is fixing with cross-arm, insulation mandrel 2 effectively supports zinc oxide resistance sheet 3, avoid its distortion or crooked, long service life, easy to process, when being connected by parallel groove clamp between binding post 6 and the high-tension cable, easy to connect.
As shown in Figure 2, described flange 1 is triangle.Simple in structure, save material.
Claims (2)
1. lightning arrester, comprise flange (1), it is characterized in that: fixedly there is insulation mandrel (2) center of flange (1), the outer a plurality of zinc oxide resistance sheets that are superimposed (3) that are with of insulation mandrel (2), zinc oxide resistance sheet is cast with silicon rubber umbrella cover (4) outward, the top of zinc oxide resistance sheet is electrically connected cable (5), and the termination of cable (5) is provided with binding post (6).
2. a kind of lightning arrester according to claim 1, it is characterized in that: described flange (1) is triangle.
