6ES7136-6RA00-0BF0 electrical components are Zener diodes manufactured to provide voltage regulation by utilizing the reverse breakdown state of a PN junction, where the current can vary over a wide range while the voltage remains essentially constant. This diode is a semiconductor device with very high resistance up to the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance drops to a very low value; in this low-resistance region, the current increases while the voltage remains constant. Zener diodes are graded according to their breakdown voltage. Due to this characteristic, Zener diodes are mainly used as voltage regulators or voltage reference elements. Zener diodes can be connected in series for use at higher voltages, allowing for higher stabilized voltages through series connection.

6ES7136-6RA00-0BF0 electrical component composition

1. The wiring harness is designed to facilitate installation and maintenance, ensuring that electrical equipment can operate under the most severe conditions. It integrates wires of different specifications and colors used by various electrical devices in the vehicle through reasonable arrangement, bundling them together with insulating materials to ensure completeness and reliability. 2. Proper selection of wire cross-sectional area and color codes: ① Correct selection of wire cross-sectional area: Electrical equipment on the vehicle selects the wire cross-sectional area based on the load current magnitude. For electrical equipment operating for extended periods, 60% of the wire's actual current-carrying capacity may be selected; for short-duration operation, 60%-109% of the wire's actual current-carrying capacity may be used. ② Selection of wire color codes: To facilitate identification and maintenance, wires in the harness use different colors. For ease of annotation in circuit diagrams, wire colors are represented by letters, with corresponding color explanations provided in each wiring diagram.

6ES7136-6RA00-0BF0 electrical component principle

The Hall voltage changes with the magnetic field strength: the stronger the magnetic field, the higher the voltage; the weaker the magnetic field, the lower the voltage. The Hall voltage value is very small, typically only a few millivolts, but after amplification by an amplifier in an integrated circuit, the voltage can be amplified sufficiently to output a stronger signal. To enable the Hall integrated circuit to function as a sensor, mechanical methods are used to change the magnetic field strength. A rotating impeller serves as a switch to control magnetic flux. When the impeller blades are in the air gap between the magnet and the Hall integrated circuit, the magnetic field is diverted away from the integrated chip, causing the Hall voltage to disappear. Thus, changes in the output voltage of the Hall integrated circuit indicate a specific position of the impeller drive shaft. Based on this working principle, the Hall integrated circuit chip can be used as an ignition timing sensor. Hall effect sensors are passive sensors that require an external power supply to operate, a feature that enables them to detect low-speed operation.

6ES7136-6RA00-0BF0 electrical component requirements

1. Copper and aluminum rods commonly used for power cables are passed through one or several drawing dies using a wire drawing machine at ambient temperature, reducing their cross-section, increasing their length, and improving their strength. Wire drawing is the first process in wire and cable manufacturing companies, and the key process parameter is die matching technology. 2. Copper and aluminum single wires are heated to a specific temperature to improve toughness and reduce strength through recrystallization, meeting the requirements for conductive cores in wires and cables. The key to the annealing process is to prevent oxidation of the copper wires. 3. To improve the flexibility of power cables for easier laying and installation, the conductive core is formed by stranding multiple single wires. Stranding methods are classified into regular stranding and irregular stranding. Irregular stranding includes bunch stranding, concentric composite stranding, and special stranding. To reduce the occupied area of the conductor and minimize the geometric dimensions of the power cable, compacted stranding is used during conductor stranding, transforming the standard circular shape into semi-circular, sectoral, tile-shaped, and compacted circular shapes. This type of conductor is primarily used in power cables. 4. Plastic power cables mainly adopt extruded solid insulation layers. The tolerance of the insulation thickness is a major indicator of the extrusion process quality. Most product structural dimensions and their tolerances are clearly specified in standards. The surface of the plastic insulation layer must be smooth, free from defects such as roughness, scorching, or impurities. The cross-section of the insulation layer must be dense and robust, with no visible pinholes or bubbles. 5. Multi-core power cables are generally stranded into a circular shape to ensure form stability and reduce the cable profile. The stranding mechanism is similar to conductor stranding, but due to the larger lay length, non-back-twist methods are mostly used. Technical requirements for cabling include: preventing twisting of the cable caused by flipping of shaped insulated cores, and avoiding damage to the insulation layer. During cabling, two additional processes are usually performed: filling, to ensure the roundness and stability of the cable after cabling, and binding, to keep the cable core tight. 6. To protect the insulated cores from damage by the armor, appropriate protection is applied to the insulation layer. Inner sheaths are classified into extruded inner sheaths (separation sleeves) and wrapped inner sheaths (cushioning layers). Wrapped cushioning layers replace binding tapes and are applied synchronously with the cabling process. 7. For power cables laid underground that may withstand certain positive pressure during operation, an internal steel tape armor structure can be selected. For power cables laid in environments subject to both positive pressure and tensile forces (such as in water, vertical shafts, or soil with significant elevation differences), a structure with internal steel wire armor should be selected. 13. The outer sheath is the structural component that protects the insulation layer of the power cable from environmental corrosion. The main functions of the outer sheath are to improve the mechanical strength of the power cable, resist chemical corrosion, prevent moisture absorption, prevent water ingress, and inhibit combustion. Depending on the specific requirements for the power cable, a plastic sheath is directly extruded using an extruder.
