1. Measure the DC resistance, measure the DC resistance of each phase of the high and low voltage windings with a bridge, and see if the resistance between the phases is balanced, whether it is consistent with the factory data of the manufacturer. If the phase resistance cannot be measured, the line resistance can be measured. The DC resistance value can be judged whether the winding is complete, whether there is a short circuit or a judgment condition, and whether the contact resistance of the tap changer is normal. If the DC resistance changes after switching the tap changer, the problem is at the tap contact point. Above, rather than in the winding itself, the above test can also check the bushing guides and leads, and the connection between the leads and the windings is good. The present invention provides a method for controlling the temperature of a flue-cured electronic cigarette and a flue-cured electronic cigarette. The flue-cured electronic cigarette includes an N-section heating body, where N is an integer greater than 1, and the heating body is used for heating tobacco. The method for controlling the temperature of the flue-cured electronic cigarette includes: the flue-cured electronic cigarette heats the i-th heating body, and i is an integer greater than 0 and less than N; after the first preset time, the flue-cured electronic cigarette pairs the i+ The first stage heating body is heated; after the second preset time, the flue-cured electronic cigarette stops heating the i-th stage heating body, and continues to heat the i+1th stage heating body. The technical solution solves the problem of unbalanced smoke output of flue-cured electronic cigarettes during multi-stage heating.The present invention provides a method for controlling the temperature of a flue-cured electronic cigarette and a flue-cured electronic cigarette.

2. Measure the insulation resistance. Use Megohmmeter to measure the insulation resistance value between each winding and winding to ground and R60/R15. The measured data value of the base can judge whether the insulation of each side winding is damp or not, and whether there is no impact between batches and ground. Wear and flash.
3. Measure the dielectric loss by tgQ. The GY-type Xilin bridge is used to measure the dielectric loss factor tgq between windings and windings to the ground. Based on the test results, it can be judged whether the insulation of each side winding is damp and whether there is overall deterioration.
4. The insulating oil sample is used for simplified testing. Use a flash point meter to measure whether the flash point of the insulating oil is lowered, whether the insulating oil has carbon particles or paper scraps, and pay attention to the smell of the oil sample. If there is a gas chromatograph analyzer, the gas content in the oil can be measured. Use the above method to judge the type of fault and its nature.
5. No-load test, carry out no-load test on the toilet, measure the three-phase no-load current and no-load loss value, to judge whether there is any fault between the core silicon steel sheets of the transformer, whether the magnetic circuit has short circuit, and the short circuit of the coil. phenomenon.
