It is dangerous to open the cover of electronic instruments with high voltage transformers or capacitors.

All high-voltage transformers and the like are dangerous. The voltage of common high-voltage transformers is above 10kV, and the power supply voltage fluctuates to some extent. During off-peak hours, the supply voltage may be much higher and the capacitor may break down at any time. Therefore, the withstand voltage of the capacitor shall not be less than 1.4 times of the power supply voltage. The voltage on the capacitor provided by electricity is usually not greater than the voltage. If it does happen, it is greater than the supply voltage, and the capacitor will discharge the power supply.

Power transformers are sensitive to temperature, and the test results brought by different ambient temperatures are bound to be different, especially the specific materials that make up power transformers, and the influence of temperature is more prominent. During the test, with the increase of temperature, the insulation resistance of high voltage transformer will decrease, which will have a great impact and threat on the test results. Therefore, when the power transformer is suddenly turned on, there will be fluctuations, which will lead to arc and affect life safety.

The purpose of transformer

High-voltage transformer is a common electronic device in electronic products, and it is an electromagnetic induction device. It is used to convert low-frequency and low-voltage into low-frequency and high-voltage when alternating current passes through the primary winding, and the transformer generates an alternating magnetic field. Through the induction of the alternating magnetic field, the secondary winding correspondingly generates an alternating magnetic field and generates an alternating electromotive force. The voltage of the secondary winding is related to the turns ratio of the secondary winding, that is, the voltage is proportional to the turns.

The main function of high pressure is to convert low pressure into required high pressure. Insulation is particularly important in the production process. The unqualified products of many manufacturers are mainly reflected in insulation treatment, and insulation is the most important thing in the production of high-voltage transformers. The fields where electronic products need high-voltage transformers are divided into the following categories: medical devices such as X-ray machines, high-potential therapeutic devices, printing, electrostatic treatment, electrostatic removal by microelectronics, air purification, oil smoke and waste gas treatment, etc.
