CSFELEKTRO electrical components refer to mechanical equipment that converts mechanical energy into electrical energy. It is driven by hydraulic turbines, steam turbines, diesel engines, or other prime movers, converting the energy from water flow, air flow, fuel combustion, or nuclear fission into mechanical energy transmitted to the generator, which then converts it into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. There are many types of generators, but their operating principles are all based on the laws of electromagnetic induction and electromagnetic force. Therefore, the general principle of their construction is to use appropriate magnetic and conductive materials to form magnetic circuits and circuits that undergo mutual electromagnetic induction, thereby generating electromagnetic power to achieve the purpose of energy conversion.

CSFELEKTRO electrical component structure

The main purpose of fiber optic connectors is to achieve fiber splicing. Fiber optic connectors, which are widely used in fiber optic communication systems, come in many types with different structures. However, upon closer examination, the basic structure of various types of fiber optic connectors is consistent: most fiber optic connectors generally use high-precision components (consisting of two ferrules and one coupling tube, totaling three parts) to achieve aligned connection of the fibers. This method involves inserting and fixing the fiber into the ferrule, polishing the ferrule surface, and achieving alignment within the coupling tube. The outer component of the ferrule is made of metal or non-metallic materials. The mating end of the ferrule must be polished, while the other end typically uses a strain relief member to support the fiber or fiber optic cable to release stress. The coupling tube is generally made of two halves synthesized from ceramic, bronze, or other materials, forming a tight cylindrical component, often equipped with metal or plastic flanges to facilitate the installation and fixation of the connector. To align the fibers as precisely as possible, the machining precision requirements for the ferrule and coupling tube are very high.

CSFELEKTRO electrical component principle

A DC power supply has two electrodes, positive and negative. The positive electrode has a higher potential, and the negative electrode has a lower potential. When the two electrodes are connected to the circuit, they maintain a constant potential difference between the two ends of the circuit, thereby forming a current from the positive electrode to the negative electrode in the external circuit. Relying solely on the difference in water levels cannot maintain a steady water flow; however, using a water pump to continuously move water from a lower level to a higher level can maintain a certain water level difference, forming a steady water flow. Similarly, relying solely on the electrostatic field generated by electric charges cannot maintain a steady current. With the help of a DC power supply, non-electrostatic actions (referred to as "non-electrostatic forces") can be used to return positive charges from the negative electrode with lower potential through the interior of the power supply to the positive electrode with higher potential, thereby maintaining the potential difference between the two electrodes and forming a steady current. Therefore, a DC power supply is an energy conversion device that converts other forms of energy into electrical energy to supply the circuit, maintaining the steady flow of current.

CSFELEKTRO electrical component applications

The most basic application of ordinary thyristors is controlled rectification. The diode rectifier circuit, which is familiar to everyone, belongs to uncontrolled rectifier circuits. If the diodes are replaced with thyristors, a controlled rectifier circuit can be formed. Taking the simplest single-phase half-wave controlled rectifier circuit as an example, during the positive half-cycle of the sinusoidal AC voltage U2, if the gate of VS does not receive a trigger pulse Ug, VS will still not conduct. Only when U2 is in the positive half-cycle and a trigger pulse Ug is applied to the gate externally will the thyristor be triggered into conduction. Drawing its waveforms (c) and (d), voltage UL appears across the load RL only when the trigger pulse Ug arrives. If Ug arrives earlier, the thyristor conducts earlier; if Ug arrives later, the thyristor conducts later. By changing the arrival time of the trigger pulse Ug at the gate, the average value of the output voltage UL across the load can be adjusted. In electrical engineering technology, half a cycle of AC electricity is often defined as 180°, called the electrical angle. Thus, in each positive half-cycle of U2, the electrical angle experienced from the zero value to the instant the trigger pulse arrives is called the control angle α; the electrical angle during which the thyristor conducts in each positive half-cycle is called the conduction angle θ. Clearly, both α and θ are used to indicate the conduction or blocking range of the thyristor during the half-cycle where it withstands forward voltage. By changing the control angle α or the conduction angle θ, the average value of the pulsed DC voltage UL across the load is changed, achieving controlled rectification. Low-power plastic-sealed bidirectional triacs are typically used in sound and light control lighting systems. The rated current is less than 5A. Large and medium-power plastic-sealed and iron-sealed thyristors are typically used in power-type controlled voltage regulation circuits, such as adjustable output DC power supplies. High-power high-frequency thyristors are typically used in industry, such as in high-frequency melting furnaces.
