Equipment having live line water washing and deicing operation functions for power transmission system and application method of equipment

Abstract

The invention discloses equipment having live line water washing and deicing operation functions for a power transmission system and an application method of the equipment. The equipment comprises a crawler chassis, a rotary support, a horizontal rotary table, an insulation operation arm and a washing device; the horizontal rotary table is fixed to the crawler chassis through the rotary support; the insulation operation arm comprises an insulation large arm and an insulation small arm that are hinged mutually; one side of the horizontal rotary table is connected with a rotary disc arranged in the vertical direction; the outer side of the rotary disc is connected with a mounting seat; a large arm driving gear motor and a small arm driving gear motor are arranged on the mounting seat; the lower end of the insulation large arm is hinged to an output shaft of the large arm driving gear motor; the insulation small arm is hinged to an output shaft of the small arm driving motor through a drag link mechanism; a rotary disc driving device is arranged on the horizontal rotary table; and the washing device is connected with the upper end of the insulation operation arm and carries out close range washing on insulators. The horizontal rotary table, the rotary disc and the two driving gear motors are matched for use, so that the equipment has the advantages of position adjustment accuracy, high cleaning efficiency, a good cleaning effect and low water consumption.

Description

technical field [0001] The invention relates to an operation equipment for a power transmission system, in particular to a washing and deicing operation equipment for a power transmission system with electrified water. Background technique [0002] The substation is an outdoor equipment. During long-term operation, dust and air pollutants are easy to deposit on the surface of its post insulators, which will affect the insulation effect of the post insulators and easily generate high-voltage discharges. Therefore, it needs to be cleaned regularly. In addition, in winter, the insulators of the substation pillars are easily covered with ice, which will not only cause the switchgear of the substation to refuse to move due to freezing, but also cause the insulation performance of the insulators to decrease, the insulation equipment to be strongly arced, and even flashover occurs. [0003] The live water washing operation has been gradually carried out in the domestic power system...

AI Technical Summary

Problems solved by technology

[0005] 1. For high-pressure water cleaning operations that require large caliber and long range, due to the reverse thrust of high-pressure water, it is very easy for the high-pressure water column to deviate from the equipment that needs to be rinsed, which reduces the impact of charged water rinse. efficiency of work;

[0006] 2. During flushing, the labor intensity of the operators is high, they are prone to fatigue, the flushing efficiency and effect are not easy to control, and the synchronization requirements for multiple flushing operators are relatively high;

[0007] 3. If the dirt has strong adhesion, water flushing alone cannot fully achieve the desired decontamination effect;

[0008] 4. If the room temperature is lower than zero, the conventional water truck cannot work, the ultrapure water cannot be produced, and the charged water washing work will not be carried out;

[0009] 5. Even if the water-making equipment can heat the ultra-pure water during the water-making process, due to the long distance when washing with a hand-held water gun, the heat of the water will be lost quickly, and the temperature of the washing water will drop quickly, making it difficult to achieve the desired deicing effect ;

[0010] 6. Since the operator is working on the ground, the spray height is limited, and the requirements for water volume and nozzle diameter are relatively high;

[0011] 7. Since the operators are working in the high-voltage electric field, the requirements for the psychological quality of the personnel are relatively high;

[0012] 8. Due to the large water consumption during flushing, single-stage heating cannot meet the water temperature requirements during deicing
