Abstract

The invention discloses a rechargeable graphite furnace power supply which comprises a charging power supply, a charging controller, a first temperature rise controller, a main controller, a graphite furnace temperature sensor, a charging power supply voltage sensor and an external power supply voltage sensor, wherein the charging controller is used for switching on an external power supply to charge the charging power supply; the first temperature rise controller is used for switching on the charging power supply to supply power to a graphite furnace; the graphite furnace temperature sensor is used for detecting the temperature of the graphite furnace; the charging power supply voltage sensor is used for detecting the voltage of the charging power supply; the external power supply voltage sensor is used for detecting the voltage of the external power supply; and the main controller is used for controlling the charging controller and the first temperature rise controller. By using therechargeable graphite furnace power supply, the charging power supply can be used for individually supplying the power to the graphite furnace; and the external power supply and the charging power supply can also be simultaneously used for supplying the power to the graphite furnace for ensuring power supply stability, thereby ensuring the temperature rise rate of the graphite furnace.

Description

Technical field [0001] The invention relates to a graphite furnace power supply, in particular to a rechargeable graphite furnace power supply. Background technique [0002] Graphite furnace is the core part of instruments such as atomic absorption spectrophotometer, which is directly related to the grade index of the instrument. [0003] Among them, the heating rate is a key indicator of the graphite furnace system, and increasing the heating rate is also the goal pursued by the graphite furnace system. The stability of the power supply is the key to whether the heating rate can be increased, and a high-power power supply is usually used to power the graphite furnace. Due to the limited material quality of traditional transformer-type power supplies, it is difficult to improve the power supply capacity, which limits the increase in the heating rate of the graphite furnace system; moreover, the traditional power supply is easily affected by the grid environment and also affects th...
