EXSYS Vertriebs electrical components Germany EXSYS Vertriebs model EXSYS Vertriebs price

EXSYS Vertriebs electrical components consist of wire wound turn by turn around an insulating tube. The wires are mutually insulated, and the insulating tube can be hollow or contain an iron core or magnetic powder core. Inductor coils are devices that operate based on the principle of electromagnetic induction. When current flows through a wire, it generates an electromagnetic field around the wire, and this electromagnetic field induces effects on the wire itself within the field range. The effect on the wire generating the electromagnetic field is called 'self-inductance', i.e., the changing current produced by the wire itself generates a changing magnetic field, which further affects the current in the wire; the effect on other wires within this electromagnetic field range is called 'mutual inductance'. The electrical characteristics of inductor coils are opposite to those of capacitors: 'passing low frequencies and blocking high frequencies'. High-frequency signals encounter significant resistance when passing through inductor coils and struggle to pass through, whereas low-frequency signals face less resistance and can pass through more easily. The resistance of inductor coils to direct current is almost zero. Resistance, capacitance, and inductance all present certain resistance to the flow of electrical signals in circuits, which we call 'impedance'. The impedance presented by inductor coils to current signals utilizes the self-inductance of the coil. Inductor coils are sometimes abbreviated as 'inductance' or 'coil', represented by the letter 'L'. When winding inductor coils, the number of turns is generally referred to as the 'number of turns' of the coil.

EXSYS Vertriebs electrical component applications

Dedicated solid-state relays can feature short-circuit protection, overload protection, and overtemperature protection. When combined with hardwired logic in a fixed package, they can form intelligent modules tailored to user requirements for direct use in control systems. Solid-state relays are widely used in computer peripheral interface equipment, constant-temperature systems, temperature regulation, electric furnace heating control, motor control, CNC machinery, remote control systems, and industrial automation devices; signal lights, dimming, flashers, stage lighting control systems; instruments and meters, medical devices, copiers, automatic washing machines; automatic fire protection and security systems, as well as switching switches for power capacitors used in grid power factor compensation. Additionally, they are extensively used in chemical, coal mining, and other environments requiring explosion-proof, moisture-proof, and corrosion-resistant characteristics.

EXSYS Vertriebs electrical component principles

When high-frequency current flows through a conductor, it generates an electric field and magnetic field in the surrounding space. Based on the spatial distribution characteristics of the electromagnetic field, it can be divided into near zone, intermediate zone, and far zone. Let R be the distance from a point in space to the conductor. In the region where R ﹤﹤ λ/2π, it is called the near zone, where the electromagnetic field has a close relationship with the current and voltage in the conductor. In the region where R﹥﹥λ/2π, it is called the far zone, where the electromagnetic field can propagate away from the conductor into space. Its changes lag behind the current and voltage on the conductor, and the propagated electromagnetic waves no longer have a direct connection with the current and voltage on the wire. This region's electromagnetic field is called the radiation field. It must be pointed out that when the length of the wire L is much smaller than the wavelength λ, the radiation is very weak; when the length of the wire L increases to be comparable to the wavelength, the current on the wire will increase significantly, thus forming stronger radiation. Transmitting antennas utilize this property of the radiation field, allowing transmitted signals to radiate fully into space after passing through the transmitting antenna. How to make a conductor an effective radiating system? First, let us analyze the situation on transmission lines. On parallel two-wire transmission lines, to ensure only energy transfer without radiation, the structure of the two wires must be symmetrical, with corresponding points having equal but opposite currents, and the distance between the two wires<π. To effectively radiate the electromagnetic field, the symmetry of the transmission line must be disrupted, such as separating the two conductors at a certain angle or removing one side, etc., which breaks the symmetry and produces radiation. Separating open-ended transmission lines or conductors at a distance of π/4 from the terminal results in the current at the terminal being in phase rather than out of phase, causing the radiation fields at spatial points to add up in phase, forming an effective radiation system. This is the simplest and most basic unit antenna, known as a half-wave dipole antenna, with a characteristic impedance of 79Ω. After electromagnetic waves are radiated from the transmitting antenna, they propagate in all directions. If a symmetric dipole is placed in the direction of propagation, an induced electromotive force will be generated on the antenna dipole under the influence of the electromagnetic wave. If the antenna is connected to receiving equipment at this time, high-frequency current will be generated at the input end of the receiving equipment. Thus, the antenna serves as a receiver, converting electromagnetic waves into high-frequency current, meaning it acts as a receiving antenna. The quality of reception depends not only on the strength of the radio waves but also on the antenna's directivity and the matching between the half-wave dipole and the receiving equipment.

EXSYS Vertriebs electrical component usage

1, apply moderate force when tightening connections to prevent stripping bolts and nuts due to excessive force. Replace stripped bolts and nuts promptly and do not continue working with damaged parts. 2, when using a screwdriver to tighten or loosen screws, ensure the screwdriver fits snugly against the screw before applying force to prevent slipping and damaging the screw, especially for common circuit breakers inside cabinets. 3, if you encounter bolts or nuts that are difficult to remove, do not act rashly to avoid deformation, which makes removal even harder. Instead, tap gently or apply a screw loosening agent or dilute hydrochloric acid before attempting removal again. 4, do not use pliers to tighten or loosen bolts and nuts to prevent damage. When using an adjustable wrench, adjust the opening properly to avoid deforming the bolt or nut, making it difficult to disassemble. 5, a single terminal block allows a maximum of two wires of the same type and specification to be connected. 6, for terminals prone to loosening or poor contact, wire connectors must be secured in a "?" shape to increase contact area and prevent loosening. 7, when connecting wire joints or lugs, non-copper or poorly conductive washers are strictly prohibited in between. 8, when connecting wire joints, the contact surface must be smooth and free of oxidation. When connecting lugs or copper bars, clean the contact surface and apply conductive paste before tightening. 9, when connecting temporary wires, fold single-strand soft wires once before connecting to the lower terminal of the circuit breaker; single-core hard wires should be connected in a "?" shape to the lower terminal of the circuit breaker. 10, for high-voltage motor wiring, no poorly conductive washers, such as galvanized nuts, flat washers, or spring washers, are allowed between the motor output and the cable connecting the motor. 12, when wrapping cables or other equipment requiring insulation protection with insulating tape, wrap the insulation layer from one end to the other with overlapping layers, ensuring at least one complete back-and-forth wrap.
