Description

Technical Field

[0001] The invention relates to the technical field of water-cooled compensators, and in particular to a two-end quick-change water-cooled compensator. Background Art

[0002] Water-cooled compensators are a type of equipment used in piping systems, mainly used to compensate for the thermal expansion and contraction of pipes due to temperature changes. Through effective design principles, it can absorb the stress of thermal expansion or contraction in the piping system, maintain the normal operation of the pipeline, and ensure the stability and safety of the pipeline. Water-cooled compensators are widely used in piping systems in industries such as petroleum, chemical, electric power, and steel, especially high-temperature pipelines and steam pipelines.

[0003] When designing the ladle refining furnace, the short-circuit system is the main equipment of the refining furnace. Its function is to transmit the secondary current generated by the transformer to the smelting station and deliver the main energy efficiency. The short-circuit mainly includes compensators, short-circuit copper tubes, water-cooled cables, short-circuit brackets and accessories. There are two types of compensators, one is a dry compensator and the other is a water-cooled compensator. The two ends of the traditional water-cooled compensator are connected to the transformer outlet and the short-circuit copper tube respectively by plug-in type. When the plug-in water-cooled compensator leaks or fails, the transformer needs to be withdrawn as a whole, and all compensators and terminal connections need to be stopped and dismantled, which is time-consuming and labor-intensive.

[0004] At the same time, the existing water-cooled compensator used in ladle refining furnaces mainly ensures the stability of the temperature in the ladle through water cooling technology to avoid overheating and damage to the equipment. A coating is used on this compensator to protect its surface to prevent corrosion by high-temperature molten metal. However, if the coating is broken, peeled or damaged, and it is not convenient to automatically check and repair it, the coating damage that is not repaired in time will cause the metal surface to be directly exposed to the harsh environment, and it is easy to be corroded by corrosive media such as molten metal and oxides, shortening the service life of the equipment.
