Embodiment
[0029] Such as Figure 1-2 As shown, a gas analysis device based on different altitudes includes a main control board, an oxygen sensor, an operational amplifier circuit, a pressure sensor, and a sulfur hexafluoride sensor. It also includes an air pump, which is connected with a solenoid valve, and the solenoid valve is used to control the suction volume of the air pump; the solenoid valve is electrically connected to the main control board, and the main control board controls the opening and closing of the solenoid valve, thereby controlling the working time t of the air pump, so as to To control the amount of gas drawn, the outlet of the air pump is connected to an air chamber, and the main control board is located in the air chamber.
[0030] In this example, if figure 2 As shown, the output end of the oxygen sensor is electrically connected to the operational amplifier circuit, the output end of the operational amplifier circuit is electrically connected to the input end...

The invention discloses a gas analysis device based on different altitudes. The gas analysis device comprises a main control board, an oxygen sensor, an operational amplifier circuit, a pressure sensor and a sulfur hexafluoride sensor. By arranging the pressure sensor, the device can adapt to working environments at different altitudes, and calibration in other modes is not needed; the working duration of an air pump is adjusted according to the air pressure conditions at different altitudes in combination with the working flow of the air pump at different air pressures, so that quantitative air is accurately extracted, and the precision, intelligence and stability of the whole system are improved; and because the numerical value change of the air pressure sensor in the air exhaust processis larger than the numerical value change when air is not exhausted, the numerical value can also be used as an auxiliary tool to judge whether the system is in a normal working state or not.
Description
technical field [0001] The invention relates to gas collection and analysis, in particular to a gas analysis device based on different altitudes. Background technique [0002] With the extensive use of power equipment, sulfur hexafluoride gas is relatively common in power equipment; sulfur hexafluoride gas itself is not toxic, but the gas in the equipment and the high-voltage arc will produce toxic substances, and with the operation and aging of the equipment , the sulfur hexafluoride gas in the tank will leak into the air, causing harm to the environment and the human body. Contents of the invention [0003] In order to solve the above-mentioned defects in the prior art, the present invention provides a gas analysis device based on different altitudes. The present invention can perform accurate measurement and analysis of sulfur hexafluoride at each monitoring point at different altitudes, with stable performance , high precision and low cost. [0004] In order to achie...
