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
[0014] Below, the present invention will be further described in conjunction with the accompanying drawings.
[0015] 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.
[0016] 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...

The invention discloses an electrified fastening rod for a middle-phase insulator screw cap, which is used for fastening the middle-phase insulator screw cap. The electrified fastening rod comprises an insulated operating lever, a socket wrench positioned at one end of the insulated operating lever and a transmission mechanism positioned at the other end of the insulated operating lever, wherein the insulated operating lever is internally provided with an insulated transmission shaft one end of which is sleeved in the socket wrench while the other end is connected with the transmission mechanism; the transmission mechanism comprises a shell body, a second gear wheel, a first gear wheel and a screw cap sleeve, wherein the second gear wheel is arranged in the shell body; the first gear wheel is meshed and connected with the second gear wheel; the screw cap sleeve is fixed on the first gear wheel coaxially and used for fixing middle-phase insulator screw cap; and the second gear wheel and the insulated transmission shaft are fixed coaxially, so that the rotation of an insulated transmission shaft drives the second gear wheel to rotate. The electricfied fastening rod is convenient to operate, makes up the defect that the prior art has certain requirements for the road condition, and ensures the reliable electricity supply for residents.
Description
technical field [0001] The invention relates to a live fastening rod, in particular to a live fastening rod used for a middle-phase 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,...
