Abstract

The invention discloses an evaporative cooling medium leakage monitoring and treating system. The evaporative cooling medium leakage monitoring and treating system comprises a medium monitoring device and a medium treating device, wherein the medium monitoring device comprises an oxygen sampling box, a cooling medium sampling box, a sampling pipe and a monitoring controller, both the oxygen sampling box and the cooling medium sampling box are installed on the inner wall of a motor fan housing, and the cooling medium sampling box is located below the oxygen sampling box; the medium treating device comprises an air suction nozzle, a pipeline and a medium recovering processor, the air suction nozzle is installed inside the motor fan housing, the medium recovering processor is installed outside the motor fan housing, and the air suction nozzle is connected with the medium recovering processor through the pipeline; the monitoring controller and the medium recovering processor are connected through a cable, and the oxygen sampling box and the cooling medium sampling box are connected with the monitoring controller through the sampling pipe. According to the evaporative cooling medium leakage monitoring and treating system, redundant gas-state cooling media are sucked and treated through the medium treating device, in this way, the content of gas-state cooling media in the fan housing can be effectively controlled, and the personal safety of workers is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a monitoring and processing system when the cooling medium inside the stator bar of an evaporative cooling electric motor leaks into the wind cover of the electric motor. Background technique [0002] The stator winding of the motor is composed of several copper wire rods, and several wire rods are embedded in the slot of the stator core made of silicon steel sheets as a group. When the motor is running, both the stator winding and the iron core will generate heat, and the heat energy generated by the stator winding must be taken away by the cooling medium. The cooling method of the stator of the existing evaporative cooling motor is as follows: the liquid cooling medium is poured into the hollow conductor of the motor stator bar, and the motor stator is cooled by using the principle of the liquid cooling medium vaporizing and absorbing heat. [0003] The stator of the m...
