CARBOGNIN electrical components Germany CARBOGNIN model CARBOGNIN price

CARBOGNIN electrical components are current fuses that provide overload protection. When a circuit fault or abnormality occurs, the current continuously rises. This elevated current may damage certain important components in the circuit, burn out the circuit, or even cause a fire. If a fuse is correctly installed in the circuit, it will melt and cut off the current when the current abnormally rises to a certain level and temperature, thereby protecting the safe operation of the circuit. With the fuse correctly installed in the circuit, the fuse will melt and cut off the current when the current abnormally rises to a certain level and temperature, protecting the safe operation of the circuit. The fuse invented by Edison was used to protect expensive incandescent lamps at the time. With the development of the times, fuses protect electrical equipment from damage due to overcurrent and overheating, avoiding serious damage to electronic equipment caused by internal faults.

CARBOGNIN electrical component principle

The basic principle of a multimeter is to use a sensitive moving-coil DC ammeter (microammeter) as the meter head. When a small current passes through the meter head, there will be a current indication. However, the meter head cannot handle large currents, so resistors must be connected in parallel and series with the meter head to shunt or reduce voltage, thereby measuring the current, voltage, and resistance in the circuit. The measurement process of a digital multimeter converts the measured quantity into a DC voltage signal via a conversion circuit, then converts the analog voltage into a digital quantity via an analog-to-digital (A/D) converter, counts it using an electronic counter, and finally displays the measurement result directly as numbers on the display screen. The functions of measuring voltage, current, and resistance with a multimeter are implemented through the conversion circuit part, and the measurements of current and resistance are based on voltage measurement. In other words, a digital multimeter is an extension based on a digital DC voltmeter. The digital DC voltmeter's A/D converter transforms the analog voltage, which changes continuously over time, into a digital quantity. The electronic counter then counts the digital quantity to obtain the measurement result, which is displayed by the decoding display circuit. The logic control circuit coordinates the operation of the circuits, completing the entire measurement process sequentially under the action of the clock.

CARBOGNIN electrical component principle

In addition to the function of converting optical signals into electrical signals like a photodiode, a phototransistor also has the function of amplifying electrical signals. The appearance of a phototransistor is not much different from that of a general transistor. Generally, a phototransistor only leads out two terminals—the emitter and the collector—while the base is not led out. The casing also has a window to allow light to enter. To increase light exposure, the base region area is made very large, while the emitter region is smaller, so that incident light is mainly absorbed by the base region. During operation, the collector junction is reverse-biased, and the emitter junction is forward-biased. In the absence of light, the current flowing through the tube is the dark current Iceo = (1 + β) Icbo (very small), which is smaller than the penetration current of a general transistor; when there is light illumination, a large number of electron-hole pairs are excited, causing the base current Ib to increase. At this moment, the current flowing through the tube is called the photocurrent, and the emitter current Ie = (5 + β) Ib. It can be seen that a phototransistor has higher sensitivity than a photodiode.

CARBOGNIN electrical component structure

A generator is usually composed of components such as the stator, rotor, end covers, and bearings. The stator consists of the stator core, winding coils, frame, and other structural parts that fix these components. The rotor consists of the rotor core (or magnetic poles, yoke), windings, retaining rings, centering rings, slip rings, fan, and shaft. The bearings and end covers connect and assemble the stator and rotor of the generator, allowing the rotor to rotate within the stator and cut magnetic flux lines, thereby generating induced electromotive force. This is led out through terminal blocks and connected to the circuit, producing current.
