Problems solved by technology

Its disadvantage is that the transmitter and receiver are easily interfered by electromagnetic field signals, and the alarm is inaccurate
Its disadvantage is that it is expensive to use equipment such as rangefinders, which is not easy to promote and use
[0005] Although various power transmission management departments will take various precautions against insulator strings, none of them are very ideal. One of the important reasons is that power maintenance personnel cannot grasp the pollution status of insulators in a timely and accurate manner. A very important part of Shem's work

Embodiment 2

[0067] The difference between Example 2 and Example 1 is: the thickness of the electrochromic material is 1.5 mm, and the insulating rod is made of the following raw materials: 70 parts of silicone resin, 10 parts of glass fiber, methylphenyl vinyl silicon 6 parts of rubber, 15 parts of ramie fiber, 2.2 parts of dicumyl peroxide, 22 parts of chopped glass fiber, 3 parts of γ-aminopropyl triethoxysilane, 10 parts of high-density polyethylene, ethylene bis stearate 4 parts of amide, 8 parts of dimethylaminoethoxyethanol, 2 parts of modified kaolin.

[0068] The preparation method of modified kaolin is as follows: first soak kaolin with 4% (V / V) hydrochloric acid for 5 minutes, subject to the fact that the kaolin has not passed through, centrifuge at 1000 rpm for 2 minutes, collect the precipitate, dry it, and grind it into a particle size of 600 The purpose powder is ready to use.

Abstract

The invention discloses overhaul equipment for preventing a device mistakenly entering a charged interval in a power engineering operation. The overhaul equipment comprises a trolley and a support rod, wherein universal idler wheels are arranged at the bottom part of the trolley; the support rod is arranged on the trolley and is rotationally connected with the trolley; the trolley is provided with a horizontal drive mechanism for driving the support rod to rotate; the support rod is provided with an angle adjusting rod which is in rotational connection with the support rod; the support rod is provided with a vertical drive mechanism for driving the angle adjusting rod to rotate; and a laser lamp, an ultrasonic sensor and a high-power and high-precision telescope camera are arranged at a free end of the angle adjusting rod. By the overhaul equipment, surface image and fault acoustic wave collection is firstly carried out on insulators; corresponding importing, comparative analysis and fault judgment are carried out by an insulator pollution fault analysis system; an insulator pollution state and fault report is finally obtained by integrating the analysis results of two aspects; and hot-line cleaning and overhauling are carried out on the polluted insulators.

Description

technical field [0001] The invention relates to the technical field of electric power engineering maintenance equipment, in particular to a maintenance equipment for preventing accidental entry into a charged interval during electric power engineering operations. Background technique [0002] With the increasing development of industrial and agricultural production, the scale of power grid construction has developed by leaps and bounds, but there are also more and more problems. In recent years, there have been frequent occurrences of short-circuit tripping of lines caused by cranes being too close to high-voltage live equipment during construction, and even personal casualties, which have a great impact on people's lives and social activities. The reasons for such accidents include, apart from the negligence of the crane operators, whether the high-voltage equipment is charged, whether the construction equipment enters the high field strength area, and whether it is close t...
