The vibration of the signal-string is converted into a change in the magnetic field, which in turn is converted into an electrical signal for amplification. Since the pickup can accurately pick up the frequency, amplitude and weak high harmonic of the string vibration and convert it into an electric signal, and then amplify it by the amplifier, it is finally expanded by the speaker of the speaker, and the volume is not only increased. And more pleasing to the ear.
High Voltage Main Power Transformer
The main transformer, which is the main step-down transformer used for power transmission and transformation in a unit or substation, is also the core part of the substation.
The main transformer is composed of the following aspects:
1. Body: The body directly converts electromagnetic energy, which is composed of iron core, coil, lead wire, insulation, etc.
2. Oil tank and cover: mainly composed of box, cover, bottom and accessories (such as 50 valve, oil sample valve, oil drain plug, grounding bolt, etc.).
3. Protection device: mainly composed of oil conservator, oil meter, oil purifier, gas relay, Moisture Absorber, thermometer, Pressure Relief Valve, etc.
4. Cooling mode: oil immersed self cooling, oil immersed air cooling, strong oil water cooling, strong oil air cooling.
5. Outgoing line bushing: It is composed of 25/300 cable bushing and BF-6/2000, BF-1/1000, BF - l/600 and BF-1/300 bushings.
6. 25 # or 45 # transformer oil is used as transformer oil to increase insulation strength and cool down the transformer;
