Charged water washing dual-water column masing washing method and device

Abstract

The invention relates to a charged water washing dual-water column masing washing method and device, and the method comprises the following steps: (1) using two water guns for jetting out high-speed water flow beams respectively; (2) intersecting the two high-speed water flow beams by the included angle which is more than 0 degree and less than 180 degrees; and (3) transforming the beam-like water columns to radial water flow through mutual extrusion after the intersection point, and cleaning a charged device to be cleaned by using the radial water flow. The optimized scheme increases the step (4): changing the distance from the intersection point to the charged device according to the need of regulating the pressure of the water flow for cleaning the charged device. As for the used charged water washing dual-water column masing washing device, auxiliary arms, water gun supports at the tail ends of the auxiliary arms and water guns are arranged into two sets respectively. By adopting the method and the device, dead angles and dead zones can be prevented from generating, impact force can be controlled, harm to the charged device can be prevented, and the sputtering length and the region can be reduced; and the automatic control can be realized by using electrical power and hydraulic power driving elements, the operation precision can be ensured, and the operation safety can be improved.

Description

technical field [0001] The invention relates to charged water flushing operation, in particular to a method and device for charged water flushing with double water column lasing. Background technique [0002] At present, the electrified water washing operation has played a great role in preventing the flashover accident caused by the pollution of the power grid and improving the safe operation of the power grid. The live water flushing operation is to use a high resistance water column to flush the live equipment. During the operation, in order to ensure the insulation performance between the live equipment and the flushing equipment, and to ensure the safety of the operator and the flushing equipment, the length of the water column is required, and It is required that the water column should be in a straight column state within the specified length. This requires that the water column must have a relatively high pressure when it reaches the water outlet, and it has a stron...

Problems solved by technology

This makes the water column reach the charged equipment, the energy is concentrated and released in a point shape, resulting in a large impact on the live equipment and easy damage to the live equipment, especially the live equipment of non-plastic materials such as glass insulators and porcelain insulators. At the same time, due to the large impact force, its The sputtering length is large, the sputtering area is wide, and accidents such as splashing and flashing are prone to occur, especially in areas with small spaces such as substations

When flushing in a spot-like manner, it is also easy to produce dead spots, making it difficult to thoroughly clean live equipment
