Abstract
Provided is a multifunctional novel lightning protection device. On the basis of a post insulator, the post insulator is connected with a discharging electrode in order to achieve a lightning protection function of an insulating line; and the discharging electrode is connected with a grounding electrode in order to achieve an electricity verification and grounding function when the insulating line is overhauled. The position of lightning stroke can be observed by a lightning stroke nameplate on a pedestal of the post insulator. The multifunctional lightning protection device is developed in combination with these functions and in view of operating environment and has advantages of a small size and easy installation and characteristics of decreasing the load of the insulating line, preventing dangerous consequences caused by lightning stroke, and shortening the overhauling time of the insulating line.
Description
Technical field
The utility model relates to a kind of electric power lightning protection device, not only with post insulator, and with the function of electrical verification ground connection, can also effectively prevent insulated circuit lightning-caused breaking.
Background technology
At present; known lightning protection device is the load side that is installed on post insulator; when thunderbolt occurs, between the striking ball by this device and the cross-arm of insulator foot, afterflow power frequency arc is moved on starting rod and burn, thereby protection insulated conductor avoids burn broken string.But many lightning protection device function singlenesses, need to install a series of other devices, because device is too much, to insulated circuit, cause very large burden, and line maintenance difficulty strengthens, the judgement that goes wrong and easily make the mistake.
Summary of the invention
In order to overcome the single of lightning protection device function, reduce the burden that various devices bring to insulated circuit.The utility model provides a kind of lightning protection device, and this device gathers multi-function in integral whole, and not only with post insulator, and with the function of electrical verification ground connection, can also effectively prevent insulated circuit lightning-caused breaking.
The utility model solves the technical scheme that its technical problem adopts: post insulator top is connected with sparking electrode die casting; sparking electrode adopts die cast metal; starting rod will be wrapped insulating cement; when thunderbolt occurs; between striking ball and the cross-arm of insulator foot, cause Shan Network electric discharge; form short-channel, the power frequency arc continuing moves between starting rod and the cross-arm of supporting insulator base and burns, and with guardwire, avoids burn broken string.During thunderbolt, can make the thunderbolt sign board of supporting insulator base side shoot down, be convenient to make an inspection tour personal identification.Sparking electrode and grounding electrode are single-casting, and grounding electrode grounded part does not wrap insulating cement.When line maintenance because need to be at aerial suspension the earth rod with earth connection, so the grounded part of design grounding electrode, higher than the position of horizontal direction 5 degree, and prevents with spherical (bag insulating cement) the earth rod landing hanging up.Clamp nut, briquetting and wire clamp seat are for fixed insulation wire.Insulation protective hood can have different colors, cover the part that post insulator top combines with sparking electrode, prevents bird pest and core water inlet corrosion.
The utility model lightning protection device beneficial effect is that integrated design, collects support fixing cord, lightning protection, electrical verification, is grounded on one.Diverse in function, small volume, installs simple disposable completing, and is convenient to line maintenance, is to insulated circuit lightning protection device innovation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples to the utility model further instruction.
Fig. 1 is vertical section of the present utility model structural map
In figure: 1, post insulator 2, sparking electrode striking ball 3, grounding electrode grounded part 4, sparking electrode starting rod 5, thunderbolt sign board 6, post insulator and sparking electrode die casting position 7, insulation protective hood 8, clamp nut, briquetting and wire clamp seat 9, grounding electrode spherical.
In Fig. 1 example illustrated, there is a screw side of post insulator (1) base, thunderbolt sign board (5) is installed on screw, post insulator top be connected with sparking electrode (6), sparking electrode starting rod (4) need to be wrapped insulating cement, sparking electrode striking ball (2) will be facing to the thunderbolt sign board (5) of supporting insulator base, grounding electrode (3) will and not wrap insulating cement higher than horizontal direction 5 degree, grounding electrode spherical (9) will be wrapped insulating cement, insulation protective hood (7) will cover post insulator and sparking electrode bound fraction (6), clamp nut, briquetting and wire clamp seat (8) are for fixed insulation wire.
