Testing Instrument Transformer: Leakage Current Significance of Transformer Anti-electric Strength

Dielectric strength test is an important part of transformer insulation performance test. It is used to detect the damage ability of transformer insulation materials and product structures under the action of electric field, and to check the defects of insulation performance. In the test, in addition to the specified voltage resistance, there is also a leakage current requirement. From low-power to high-power power transformers, the specified leakage current range is 1mA to 10mA.

Inspection Instrument Transformer: Removal Steps of Transformer

The transformer manufacturer of the testing instrument recommends the disassembly steps of the transformer: when the small transformer (≤ 2kV · A) is short-circuited between the internal turns of the winding, internally disconnected but no broken ends can be found, and the windings are short-circuited or burned out, the old winding needs to be removed and rewound.

Water heater transformer: how to regulate the temperature of the transformer

Water heater transformers are widely used, but when the transformer works, it will produce different temperatures. Don't underestimate this temperature, it's exquisite. And with the daily work of the transformer, if the temperature is too high, it will be harmful to the transformer core, which will affect the combustion of the transformer core to a certain extent, but if the temperature is too low, the power output transformer will also show lower voltage. Therefore, everyone must control this temperature. How to control the temperature of the transformer?

Water heater transformer: What are the voltage regulation methods of high voltage transformer?

Water heater transformers are commonly used electronic devices in electronic products. It is an electromagnetic induction device used to convert low frequency and low voltage into low frequency and high voltage. When alternating current is passed through the primary winding, the transformer generates an alternating magnetic field. By inducing an alternating magnetic field, the secondary winding also generates an alternating magnetic field to generate an alternating electromotive force. The voltage level of the secondary winding is proportional to the number of turns of the secondary winding, I .e. the voltage is proportional to the number of turns. The main function of high pressure is to convert low pressure to the required high pressure. Insulation is especially important in the production process. The unqualified products of many manufacturers are mainly reflected in the insulation treatment. good

Rice cooker transformer: What is the main purpose of the transformer?

What is the main purpose of the recommended transformer for the fine rice cooker transformer? Isolation transformer: electrical isolation-in addition to maintaining mechanical equipment, it also maintains life safety! Protection against dangerous voltages. Prevention of some accidents. The output and input capacitive coupling of the isolation transformer is small, which can suppress the effects of lightning strikes, charging and discharging, grid conversion, motor starting, and other grid drying. From this point of view, the isolation transformer is a large number of maintenance machinery and equipment.

Water purifier transformer: force effect of transformer in short circuit

The current-carrying conductor of the water purifier transformer in the magnetic field will bear the action of mechanical force. Therefore, when the current passes through the transformer winding, due to the influence of the current and the leakage magnetic field, the electromagnetic mechanical force will be generated in the winding, and the electromagnetic force is determined. Since the flux density of the leakage magnetic field is multiplied by the line current, we all know that the separation direction is determined by the left hand.
