TET14-20C 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. 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," meaning 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: they "pass low frequencies and block high frequencies." High-frequency signals encounter significant resistance when passing through an inductor coil and struggle to pass through; whereas the resistance presented to low-frequency signals is relatively small, allowing them to pass through more easily. The resistance of an inductor coil to direct current is nearly zero. Resistance, capacitance, and inductance all present certain resistance to the flow of electrical signals in a circuit; this resistance is referred to as "impedance." The impedance presented by an inductor coil 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 an inductor coil, the number of turns wound is generally referred to as the "number of turns" of the coil.

TET14-20C Electrical Component Composition

1. Generally, a fuse consists of three parts: First is the fusible element, which is the core of the fuse and serves to cut off the current when it melts. For fuses of the same type and specification, the fusible elements must have the same material, identical geometric dimensions, minimal and consistent resistance values, and most importantly, consistent fusing characteristics. Household fuses are commonly made of lead-antimony alloy. Second is the electrode part, typically consisting of two electrodes, which are important components connecting the fusible element to the circuit. They must have good conductivity and should not produce significant installation contact resistance. Third is the support part. Since the fusible element of a fuse is generally thin and soft, the support's role is to fix the fusible element and make the three parts a rigid whole for easy installation and use. It must have good mechanical strength, insulation, heat resistance, and flame retardancy, and should not exhibit phenomena such as breakage, deformation, combustion, or short circuits during use. 2. Arc extinguishing device: Fuses used in power circuits and high-power equipment not only have the three general parts of a fuse but also include an arc extinguishing device. This is because the circuits protected by such fuses not only have larger operating currents, but also have very high voltages across the ends when the fusible element melts. Often, the fusible element may have melted (fused) or even vaporized, but the current has not been cut off. The reason is that at the moment of fusing, arcing occurs between the two electrodes of the fuse under the action of voltage and current. This arc extinguishing device must have strong insulation and good thermal conductivity, and exhibit negative electronegativity. Quartz sand is a commonly used arc extinguishing material. 11. Fusing indication device: Some fuses have a fusing indication device. Its function is to cause a certain visual change in the fuse itself after it operates (fuses), making it easy for maintenance personnel to detect, such as emitting light, changing color, or popping out a solid indicator.

TET14-20C Electrical Component Functions

The main purposes of disconnect switches (knife switches) are: 1, to isolate the power supply, disconnecting high-voltage maintenance equipment from live equipment, creating a clearly visible break point between them. 2, disconnect switches cooperate with circuit breakers to perform switching operations according to system operation requirements, thereby changing the system wiring configuration. 3, to connect or disconnect low-current circuits. Disconnect switches can perform the following operations: pulling and closing bypass currents of loop switches; pulling and closing grounding wires at transformer neutral points, but if an arc suppression coil is connected to the neutral point, operation is only permitted when the system is fault-free; pulling and closing voltage transformers and surge arresters; pulling and closing capacitive currents of busbars and equipment directly connected to the busbars; pulling and closing no-load lines with capacitive currents not exceeding 5 amperes; triple-pole disconnect switches can pull and close loads with voltages at or below 10 kilovolts and currents below 16 amperes. When operating disconnect switches, note that when energizing a line, first close the busbar-side disconnect switch, then the line-side disconnect switch, and finally the circuit breaker. When de-energizing a line, first open the circuit breaker, then open the disconnect switch. Do not pull or close high-voltage disconnect switches under load.

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 into a single unit through reasonable arrangement, bundling them 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 magnitude of the load current. For electrical equipment operating for extended periods, select 60% of the wire's actual current-carrying capacity; for short-term operation, use 60% to 103% of the wire's actual current-carrying capacity. ② Selection of wire color codes: To facilitate identification and maintenance, wires in the harness are differentiated by color. For ease of annotation in circuit diagrams, wire colors are represented by letters, with corresponding color explanations provided in each wiring diagram.
