Problems solved by technology
When the traditional dry-type transformer temperature controller is in use, it is easy to enter the dust in the environment when it dissipates heat inside itself, causing internal dust collection. Too much dust collection will easily cause the internal circuit to age, and at the same time, the connection between the shell and the end cover is insufficient. question

The invention belongs to the technical field of temperature controllers, and particularly relates to a dry-type transformer temperature controller which comprises a shell and an end plate installed at the end of the shell, a ventilation window is formed in the surface of the shell, a fan cover is welded to the inner surface, close to the ventilation window, of the shell, and a fan is installed in the fan cover through bolts. A magnet ring is installed in the ventilation window, the magnet ring is wrapped with dust-proof gauze, a limiting rubber pad is arranged in a gap between the ventilation window and the magnet ring, and a connecting plate is welded to the end of the shell. A magnet ring and dust-proof gauze are mounted in the ventilation window, the magnet ring is wrapped with the dust-proof gauze, and the magnet ring is fixed in the ventilation window through magnetic force, so that the magnet ring can limit the dust-proof gauze conveniently, and the convenience of mounting the dust-proof gauze in the ventilation window is improved; and meanwhile, the limiting rubber pad is mounted between the ventilation window and the magnet ring, so that the limiting rubber pad can limit the magnet ring conveniently.
Description
technical field [0001] The invention belongs to the technical field of temperature controllers, and in particular relates to a dry-type transformer temperature controller. Background technique [0002] Dry-type transformer temperature controller is a new generation of multi-functional computer temperature controller designed for the reliable operation of air-cooled dry-type power transformers. Detect the temperature rise of the dry-type power transformer package, and automatically control the start and stop of the cooling fan according to the temperature rise, over-temperature alarm until the ultra-high temperature trip to ensure the safe operation of the dry-type power transformer. When the traditional dry-type transformer temperature controller is in use, it is easy to enter the dust in the environment when it dissipates heat inside itself, causing internal dust collection. Too much dust collection will easily cause the internal circuit to age, and at the same time, the co...
