Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a remote monitoring device for a power intermediate frequency power supply. Background technique [0002] In current high-power medium-frequency induction heating systems, the rated junction temperature of high-current and high-voltage thyristors is mostly between 115°C and 125°C, and the turn-off time is affected by temperature. At present, the heat dissipation of high-power thyristors mainly depends on the circulating water cooling system, and the circulating water will block the circulating water channel with scale during long-term use. In the operation and maintenance of power equipment, it often happens that the filtered circulating water and the The phenomenon of related kits leads to the burning of thyristors and the shutdown of equipment. At present, the temperature protection of thyristor mainly relies on simple water pressure inspection and protection, which cannot...

At present, the heat dissipation of high-power thyristors mainly depends on the circulating water cooling system, and the circulating water will block the circulating water channel with scale during long-term use. In the operation and maintenance of power equipment, it often happens that the filtered circulating water and the The phenomenon of related kits leads to the burning of thyristors and the phenomenon of equipment shutdown

At present, the temperature protection of thyristor mainly relies on simple water pressure inspection and protection, which cannot effectively detect and reflect the heat dissipation performance of specific components, let alone provide effective alarm and protection. Therefore, an effective temperature monitoring device is urgently needed for intermediate frequency induction heating power supplies. The user has more powerful monitoring of the status of the core components of the equipment
