Abstract

The utility model discloses an anti-pollution-flashover damping insulation strut. The insulation strut comprises clamp devices, an insulation rod, and circuit breaking covers, wherein the insulation rod is connected with at least one circuit breaking cover, two ends of the insulation rod are respectively connected with springs, and the clamp device is connected with the insulation rod by the spring. The insulation rod is provided with umbrella skirts. The circuit breaking cover is a bowl-shaped product made of insulating material. The beneficial effects of the utility model are that, the clamp devices are connected with the insulation rod by the springs, the springs can buffer the swing of interphase power lines, reducing the friction between the clamp devices and the power lines, and the springs can also be used as movable components to prevent ice from covering the whole insulation strut, thereby preventing interphase short circuit; the circuit breaking cover is a bowl-shaped product made of insulating material, such that rainwater can be quickly removed from the insulation strut, and the rainwater flow is cut off, thereby preventing interphase short circuit; and the insulation rod is provided with the umbrella skirts, so that interphase flashover of the power lines is prevented.

Description

A kind of anti-pollution flashover damping insulation strut
Technical field
The utility model relates to the electrical network technical field of preventing and reducing natural disasters, and relates in particular to a kind of anti-pollution flashover damping insulation strut.
Background technology
Thereby overhead power line can take place to collide between line in high wind to cause phase fault to cause accidents such as lead burns out, blows, and the insulation strut occurred for solving above technical problem.The insulation strut relies on clamping device to be fixed on the adjacent power line, high wind blows power line, the insulation strut can prevent effectively that power line from running foul of each other but the swing of power line makes generation friction between power line and the clamping device, in the course of time the power line insulation sheath will be worn, the class of insulation with this power line, serious even can expose plain conductor, cause phase fault easily, threaten the safe and stable operation of electrical network.In addition, along with Chinese national economy constantly develops, air pollution is more and more serious, the close value scope of salt raises year by year, though be provided with antifouling flush paint at the insulation strut, under bad weather condition as: mist, dew, rain etc., flashover still can take place along the insulating bar of humidity, cause the electric power system pollution flashover accident, influence the power system safety and stability operation.
The utility model content
The utility model provides a kind of anti-pollution flashover damping insulation strut that can prevent power line phase fault and flashover and reduce the power line wearing and tearing.
Realize that the technical scheme that above-mentioned purpose is taked is: a kind of anti-pollution flashover damping insulation strut, comprise clamping device, insulating bar and cutout cover, described insulating bar is connected with at least one cutout cover, and described insulating bar two ends connect spring respectively, and described clamping device is connected with insulating bar by spring.
Described insulating bar arranges full skirt.
Described cutout cover is the insulating material product that is bowl-shape.
The beneficial effects of the utility model are: clamping device is connected with insulating bar by spring, spring can cushion the swing of alternate power line, thereby reduce the friction between clamping device and the power line, thereby spring is that movable part can prevent that ice and snow from covering whole insulation strut and causing phase fault simultaneously; Cutout cover is for to be bowl-shape insulating material product, thereby can make rainwater leave the insulation strut fast and block rainwater and flow the generation that prevents phase fault; Insulating bar arranges full skirt, can prevent the alternate flashover of power line.The utility model can prevent power line phase fault and flashover, reduces the power line wearing and tearing, has ensured the safe and stable operation of electrical network.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of damping insulation strut, comprise clamping device 2, insulating bar 4 and cutout cover 5, described insulating bar 4 is connected with at least one cutout cover 5, described insulating bar 4 two ends connect spring 3 respectively, described clamping device 2 is connected with insulating bar 4 by spring 3, and described cutout cover 5 is for to be bowl-shape insulating material product, and described insulating bar 4 arranges full skirt 6.The beneficial effects of the utility model are: clamping device 2 is connected with insulating bar 4 by spring 3, spring 3 can cushion the swing of alternate power line 1, thereby reduce the friction between clamping device 2 and the power line 1, thereby spring 3 can prevent that for movable part ice and snow from covering whole insulation strut and causing phase fault simultaneously; Cutout cover 5 is for to be bowl-shape insulating material product, thereby can make rainwater leave the insulation strut fast and block rainwater and flow the generation that prevents phase fault; Insulating bar 4 arranges full skirt 6, can prevent the alternate flashover of power line.The utility model can prevent power line phase fault and flashover, reduces the power line wearing and tearing, has ensured the safe and stable operation of electrical network.
