Graphite furnace and transformers used in graphite furnace

摘要

PROBLEM TO BE SOLVED: To provide a stable operation method of a transformer used in an atomic absorption spectrophotometer. The present invention relates to a graphite furnace and a transformer used in the graphite furnace, the graphite furnace includes a transformer and a temperature monitoring unit 6, and the transformer includes a primary coil and a secondary coil of the transformer. A heat conducting member disposed between the heat conducting member and a temperature sensor assembly 3 connected to the heat conducting member for detecting a temperature conducted from the heat conducting member to obtain a temperature measurement value. The temperature monitoring unit 6 is preset with a first threshold value, receives the temperature measurement value from the temperature sensor assembly 3 and, if the temperature measurement value is greater than the first threshold value, the transformer. Instruct to stop the operation of. [Selection diagram] Fig. 5
