Schoenbuch electrical components Germany Schoenbuch model Schoenbuch price

Schoenbuch electrical components are devices that use the principle of electromagnetic induction to change AC voltage. The main components are the primary winding, secondary winding, and iron core (magnetic core). Main functions include: voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). Transformers can be classified by application into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformers, test transformers, phase-shifting transformers, high-current transformers, excitation transformers, etc.

Schoenbuch electrical components composition

1. Wiring harnesses are designed to facilitate installation and maintenance, ensuring that electrical equipment can operate under the harshest conditions. Wires of different specifications and colors used by various electrical devices in the vehicle are logically arranged and bundled together with insulating material, making them complete and reliable. 2. Normal selection of wire cross-sectional area and color codes: (1) Correct selection of wire cross-sectional area; electrical equipment in the vehicle selects the wire cross-sectional area based on the load current magnitude. Electrical equipment operating for long durations can use wires with an actual current carrying capacity of 60%; electrical equipment operating for short durations can use wires with an actual current carrying capacity of 60%-101%. (2) Selection of wire color codes; to facilitate identification and maintenance, wires in the harness use different colors. For easy annotation in circuit diagrams, wire colors are represented by letters, with the corresponding colors noted in each circuit diagram.

Schoenbuch electrical components structure

The basic structure of a voltage transformer is very similar to that of a transformer; it also has two windings, one called the primary winding and the other called the secondary winding. Both windings are mounted on or wound around the iron core. There is insulation between the two windings and between the windings and the iron core, providing electrical isolation between the two windings and between the windings and the iron core. During operation, the primary winding N1 is connected in parallel to the line, and the secondary winding N11 is connected in parallel to instruments or relays. Therefore, when measuring voltage on high-voltage lines, although the primary voltage is high, the secondary voltage is low, ensuring the safety of operators and instruments.

Schoenbuch electrical components classification

1. By application: pressure-sensitive and force-sensitive sensors, position sensors, level sensors, energy consumption sensors, speed sensors, acceleration sensors, radiation sensors, thermal sensors. 2. By principle: vibration sensors, humidity-sensitive sensors, magnetic-sensitive sensors, gas-sensitive sensors, vacuum degree sensors, biosensors, etc. 3. By output signal: (1) Analog sensors convert the measured non-electrical quantity into an analog electrical signal. (2) Digital sensors: convert the measured non-electrical quantity into a digital output signal (including direct and indirect conversion). (3) Pseudo-digital sensors: convert the measured signal quantity into a frequency signal or short-period signal output (including direct or indirect conversion). (4) Switch sensors: when a measured signal reaches a specific threshold, the sensor outputs a set low-level or high-level signal accordingly. 4. By manufacturing process: Integrated sensors are manufactured using standard production processes for silicon-based semiconductor integrated circuits. Usually, part of the circuit for preliminary processing of the measured signal is also integrated on the same chip. Thin-film sensors are formed by depositing thin films of corresponding sensitive materials on a dielectric substrate (base plate). When using hybrid processes, part of the circuit can also be fabricated on this substrate. Thick-film sensors are made by coating slurry of corresponding materials onto ceramic substrates, typically made of alumina, followed by heat treatment to form the thick film. Ceramic sensors are produced using standard ceramic processes or their variants (sol-gel, etc.). After appropriate preparatory operations, the formed elements are sintered at high temperatures. There are many common characteristics between thick-film and ceramic sensor processes; in some aspects, thick-film technology can be considered a variant of ceramic technology. Each process technology has its own advantages and disadvantages. Due to lower capital investment required for research, development, and production, as well as the high stability of sensor parameters, it is more reasonable to adopt ceramic and thick-film sensors. 5. By measurement purpose: Physical sensors are made using the characteristic that certain physical properties of the measured substance undergo significant changes. Chemical sensors are made using sensitive elements that can convert chemical quantities such as the composition and concentration of chemical substances into electrical quantities. Biological sensors are made using various biological or biomaterial characteristics to detect and identify chemical components in living organisms. 6. By composition: (1) Basic sensors are the most fundamental single transduction devices. (2) Combined sensors are sensors composed of different single transduction devices. (3) Application-specific sensors are sensors composed of basic or combined sensors combined with other mechanisms. 16. By mode of action: They can be divided into active and passive sensors. Active sensors include action-type and reaction-type. Such sensors can emit a certain detection signal to the measured object, detect changes produced by the detection signal in the measured object, or form a signal by generating an effect in the measured object. Those detecting changes in the detection signal are called action-type, while those detecting responses to form signals are called reaction-type. Radar and radio frequency range detectors are examples of action-type, while photoacoustic effect analysis devices and laser analyzers are examples of reaction-type. Passive sensors only receive signals generated by the measured object itself, such as infrared radiation thermometers and infrared imaging devices.
