Research on Preventing Overheating Measures of Dry Hollow Bridge Arm Reactor

Since the site is adjacent to residential areas, the reactor arrangement needs to consider the influence of reactor noise and thermal field, which is technically difficult. Moreover, the fault caused by overheating of dry hollow shunt reactors occurs from time to time. In order to solve the above problems, according to the service conditions of dry hollow bridge arm reactors, The relationship between the structure form, size, and shape of metal parts of bridge arm reactor and the influence of overheating is studied. According to the model size of typical steel beam structural parts in the valve hall, a simplified simulation model integrating reactor and steel beam structural parts was established, and thermal field simulation research was carried out to obtain the thermal field simulation results. The control scheme to control the temperature difference between the reactor body envelope and the measures to restrain the overheating of metal parts and prevent the overheating of steel beam structure near the reactor in the valve hall are put forward.
