Problems solved by technology

[0002] At present, because the insulators used in 10 kV lines are affected by construction assembly quality, electromagnetic vibration load, wind vibration, etc., the nuts of the insulators are loose, which threatens the normal operation of the line
Insulating gloves can be used to eliminate this defect in areas that can be reached by insulated elevated vehicles. However, insulated elevated vehicles have certain requirements for road conditions. Due to the influence of terrain conditions, live work cannot be carried out in many places that vehicles cannot reach. To a certain extent, the reliability of power supply is reduced

Embodiment Construction

[0013] Below, the present invention will be further described in conjunction with the accompanying drawings.

[0014] see figure 1 , the figure shows a live fastening rod for the side-phase insulator nut, used for fastening the side-phase insulator nut (not shown in the figure), which includes an insulating operating rod 1', an An operating handle 2' at one end of the insulating operating rod 1' and a nut sleeve 3' for fastening the side-phase insulator nut at the other end of the insulating operating rod 1', the operating handle 2' and the insulating operating rod 1' They are pivotally connected by a rotating shaft 4', and the nut sleeve 3' is connected with the insulating operating rod 1' through a spherical bearing 5' so that the nut sleeve 3' can rotate circularly, and the circularly rotatable angle α is 30 Spend.

[0015] see Figure 2 to Figure 4 , the figure shows a live fastening rod for the mid-phase insulator nut of the present invention, which is used to fasten t...

Abstract

The invention discloses a method for fastening insulator screw caps. The insulator screw caps comprise a middle-phase insulator screw cap and side-phase insulator screw caps positioned on two sides. The method comprises the following steps of: fastening the middle-phase insulator screw cap first; and then fastening the side-phase insulator screw caps. The method has the advantages that: a specially-designed electrified fastening rod for the insulator screw caps is used for fastening loose middle-phase and side-phase insulator screw caps respectively, is convenient to operate, overcomes the defect that the prior art has certain requirement on road conditions, is convenient to carry by an operator, is not influenced by topographic condition, is time-saving and labor-saving, and ensures reliable power utilization of inhabitants.

Description

technical field [0001] The invention relates to a fastening method for an insulator nut. technical background [0002] At present, due to the influence of construction and assembly quality, electromagnetic vibration load, wind vibration, etc. on the insulators used in 10 kV lines, the nuts of the insulators are loosened, which threatens the normal operation of the lines. Insulating gloves can be used to eliminate this defect in areas that can be reached by insulated elevated vehicles. However, insulated elevated vehicles have certain requirements for road conditions. Due to the influence of terrain conditions, live work cannot be carried out in many places that vehicles cannot reach. To a certain extent, the reliability of power supply is reduced. Therefore, in order to meet the social and economic development and the reliable power supply of residents, and improve the reliability of power supply in the power sector, it is necessary to develop new live working tools, so tha...
