[0002] At present, the electrical components of medium and high frequency power cabinets produced by domestic manufacturers are all cooled by water. The cooling of the electrical components in the entire cabinet is composed of the water inlet main pipe, water inlet branch pipe, return water main pipe, and return water branch pipe. If the inlet and return water branch pipes are blocked, if they are not discovered in time, it will cause damage to the electrical components and the equipment cannot be produced normally, resulting in the consumption of manpower and material resources and the increase of production costs.
