FABER KABEL electrical components, German FABER KABEL models, FABER KABEL pricing

FABER KABEL electrical components are active-matrix liquid crystal displays driven by thin-film transistors. They primarily use current to stimulate liquid crystal molecules to generate points, lines, and planes, which combine with backlights to form images. IPS, TFT, and SLCD are all subclasses of LCD. Their operating principle involves changing the alignment of liquid crystal molecules under an electric field, thereby altering (modulating) the transmittance of external light sources to achieve electro-optical conversion. Then, using different excitations from the R, G, and B primary color signals, and passing through red, green, and blue primary color filter films, color reproduction in the time and spatial domains is completed.

FABER KABEL electrical component applications

The structure and characteristics of Schottky diodes make them suitable for high-frequency rectification in low-voltage, high-current output applications. At very high frequencies (such as the X band, C band, S band, and Ku band), they are used for detection and mixing, and as clamps in high-speed logic circuits. In addition to the characteristic parameters of ordinary PN junction diodes, the electrical parameters of Schottky diodes used for detection and mixing include intermediate frequency impedance, voltage standing wave ratio, and noise figure. The Schottky barrier diode is a low-power, ultra-high-speed semiconductor device. Its most significant feature is an extremely short reverse recovery time (as low as a few nanoseconds). It is commonly used as a high-frequency, low-voltage, high-current rectifier diode, freewheeling diode, and protection diode. It is also used as a rectifier diode and small-signal detector diode in microwave communication circuits. It is relatively common in communication power supplies and variable frequency drives. A typical application is in the switching circuit of a bipolar junction transistor (BJT), where a Shockley diode is connected to the BJT for clamping. This ensures that when the transistor is in the conducting state, it is actually close to the cutoff state, thereby increasing the switching speed of the transistor. The main feature of Schottky diodes is a lower forward voltage drop. For the same current, its forward voltage drop is significantly smaller. Additionally, its recovery time is short. It also has some disadvantages: relatively low voltage resistance and slightly higher leakage current. These factors must be comprehensively considered during selection.

FABER KABEL electrical component characteristics

The main characteristics of circuit breakers include: rated voltage; rated current; tripping current setting range for overload and short-circuit protection; rated short-circuit breaking current, etc. Rated ultimate short-circuit breaking capacity refers to the ability of a low-voltage circuit breaker to operate normally again and break this short-circuit current one more time after interrupting the maximum three-phase short-circuit current at its output terminals. The circuit breaker does not guarantee whether it can normally connect and disconnect thereafter. Rated service short-circuit breaking capacity refers to the ability of the circuit breaker to normally break the current multiple times when the maximum three-phase short-circuit current occurs at its output terminals. The rated service short-circuit breaking capacity is a breaking current value lower than the rated ultimate short-circuit breaking current. Generally, circuit breakers with three-stage protection functions (long-time delay for overload, short-time delay for short-circuit, and instantaneous action for short-circuit) can achieve selective protection. Most main lines (including the output terminals of transformers) use them as main protection switches. Circuit breakers without short-time delay for short-circuit protection (having only long-time delay for overload and instantaneous action for short-circuit) cannot provide selective protection and can only be used on branch circuits. "Marine Electrical Engineering" points out that for circuit breakers with three-stage protection, emphasis is placed on their service short-circuit breaking capacity value, while for circuit breakers used on branch lines, it is essential to ensure they have sufficient ultimate short-circuit breaking capacity values. A common bias is to prefer larger values rather than appropriately sized ones, believing that larger is safer. However, selecting excessively large values causes unnecessary waste. Therefore, there is no need to blindly pursue high service short-circuit breaking capacity indicators for circuit breakers on branch lines. For circuit breakers used on main lines, they must not only meet the requirements for rated ultimate short-circuit breaking capacity but also satisfy the requirements for rated service short-circuit breaking capacity. A circuit breaker is a basic low-voltage electrical appliance with overload, short-circuit, and undervoltage protection functions, capable of protecting lines and power sources. The main technical indicators are rated voltage and rated current. Circuit breakers have different functions depending on the application, with many varieties and specifications, and numerous specific technical indicators. Free tripping of circuit breakers: If the protection action closes the tripping circuit at any moment during the closing process of the circuit breaker, and the circuit breaker can reliably disconnect completely, this is called free tripping. Circuit breakers with free tripping ensure that if a short-circuit fault occurs during closing, they can disconnect quickly, preventing the expansion of the accident scope.

FABER KABEL electrical component principles

1. Gas thermometers: Hydrogen or helium is often used as the temperature-measuring substance because their liquefaction temperatures are very low, close to absolute zero, resulting in a wide measurement range. These thermometers offer high precision and are mostly used for precise measurements. 2. Resistance thermometers: Divided into metal resistance thermometers and semiconductor resistance thermometers, both are made based on the characteristic that resistance changes with temperature. Metal thermometers mainly use pure metals such as platinum, gold, copper, and nickel, as well as rhodium-iron and phosphor bronze alloys. Semiconductor thermometers mainly use carbon, germanium, etc. Resistance thermometers are convenient and reliable, and are widely used. 3. Thermocouple thermometers: These are widely used temperature-measuring instruments in industry. They are made using the thermoelectric effect. Two different metal wires are welded together to form the measuring junction, and the other ends are connected to measuring instruments to form a circuit. When the measuring junction is placed at the temperature to be measured, and there is a temperature difference between the measuring junction and the reference junction, an electromotive force is generated, causing current to flow through the circuit. By measuring electrical quantities and using the known temperature at one point, the temperature at another point can be determined. They are suitable for measuring large temperature differences between two substances and are mostly used for high-temperature and low-turbidity measurements. 4. Dial thermometers: These are dashboard-shaped thermometers, also known as room thermometers, used to measure room temperature. They are made using the principle of thermal expansion and contraction of metals. They use a bimetallic strip as the temperature-sensing element to control the pointer. The bimetallic strip is usually made by riveting a copper strip and an iron strip together, with the copper strip on the left and the iron strip on the right. Since the thermal expansion and contraction effect of copper is much more pronounced than that of iron, when the temperature rises, the copper strip pulls the iron strip to bend to the right, causing the pointer to deflect to the right (pointing to high temperature) under the drive of the bimetallic strip. Conversely, when the temperature drops, the pointer deflects to the left under the drive of the bimetallic strip. 5. Glass tube thermometers: Glass tube thermometers utilize the principle of thermal expansion and contraction to measure temperature. Due to the different expansion coefficients, boiling points, and freezing points of the temperature-measuring media, common glass tube thermometers mainly include kerosene thermometers, mercury thermometers, and red ink thermometers. Their advantages are simple structure, ease of use, relatively high measurement precision, and low price. The disadvantages are that the measurement limits and precision are limited by the quality of the glass and the properties of the temperature-measuring medium. They cannot transmit data remotely and are fragile. 6. Pressure thermometers: Pressure thermometers use the volume expansion or pressure change of liquid, gas, or saturated vapor in a closed container when heated as the measurement signal. Their basic structure consists of three parts: a bulb, a capillary tube, and an indicator gauge. The advantages of pressure thermometers are simple structure, high mechanical strength, and resistance to vibration. They are low-cost and do not require external power. The disadvantages are limited temperature measurement range, significant heat loss, and slow response time. 8. Mercury thermometers are a type of expansion thermometer and can only be used as local monitoring instruments. Using them to measure temperature is not only simple and intuitive but also avoids the errors associated with remote transmission thermometers.
