| Abstract: | Mainly introduces the composition and operating principle of the on-line monitoring device of the dry-type transformer,analyses the temperature controller hardware circuit and processing software with ADuC812 as the core.The temperature controller can detect four temperature signals simultaneously,conduct temperature display,heat dissipation motor drive,over temperature alarm,fault trip,analog signal output,achieve centralized monitoring with upper computer communication through RS-485.The experiment shows that the measuring error of temperature controller is less than ±5℃,whilst the maxim error of contact movement is 0.6℃,which can meet all the experimental demands of electromagnetic interference. |
