Description
Technical Field
The invention belongs to the technical field of power transformation operation and inspection, relates to a cleaning tool, and particularly relates to cleaning equipment for an electrified working condition of electrical equipment.
Background
In the running process of power plant power equipment in China, the problems of pollution flashover hidden danger and the like exist. The pollution flashover hidden trouble can cause serious threat to the operation of the power system, and equipment cleaning is required to be carried out regularly to eliminate the hidden trouble.
At present, when power grid equipment is cleaned in China, most cleaning modes belong to power failure cleaning modes, and the cleaning mode has the advantages of simplicity and easiness, but has some problems due to the influence of various factors. Firstly, the power failure time is uncertain, the equipment cleaning work is passive, and the dirty equipment cannot be cleaned effectively and timely. Secondly, technicians need to power off to overhaul the equipment, a post insulator may exist in the bus-side isolating switch, and the equipment is difficult to clean in a live manner, so that the cleaning work of the equipment is not thorough. Technicians stop power supply operation and safety measures in the process of overhauling equipment to cause obstacles to equipment cleaning work. The cleaning can be ensured at any time through the live cleaning, so that the safe operation of the equipment can be ensured.
At present, the electrified cleaning method in China mainly comprises the methods of electrified air blowing, electrified water washing, electrified mechanical cleaning and the like.
In the charged water rinsing process, the primary insulating material of operation is a water column. Because the water column has high flow velocity, the water column with high flow velocity can generate impact force to wash the dirt deposited on the surface of the insulator. However, the washing work is limited by factors such as the washing method and the used water quality, the installation position of equipment, the environment and the like, and the work has strong requirements on the operation technology. In the prior process of electrified water washing, flashover accidents frequently occur on adjacent equipment and washed equipment, so that the electrified water washing difficulty is high, and the electrified water washing is inconvenient to apply in a large quantity.
The surface of the insulator is swept by compressed air with air blowing sweeping, so that sweeping is more thorough. The power for the technician to clean the dirt is compressed air, and a part of the main insulation forming the cleaning operation is also compressed air. The air can raise the temperature after the compression, and the phenomenon of trachea wall condensation is very common in the process of passing through rubber insulation, so that the main insulation performance of cleaning equipment is reduced, and the phenomenon can have serious influence on the safety of live working. Meanwhile, the gas purging has a good effect on floating dust and dirt, and has a poor effect on some firm dirt, so that the method cannot be widely applied.
For the reasons, no cleaning equipment which is convenient to use, safe and efficient is available in the live cleaning operation of the electrical equipment.
