TRAFBER electrical components Germany TRAFBER model TRAFBER price

TRAFBER electrical components refer to an electrical device that disconnects the circuit by melting the fusible element with the heat generated by itself when the current exceeds a specified value. A fuse is a current protection device made based on the principle that when the current exceeds the specified value for a period of time, the heat generated by itself melts the fusible element, thereby disconnecting the circuit. Fuses are widely used in high and low voltage distribution systems, control systems, and electrical equipment as short-circuit and overcurrent protectors, and are one of the most commonly used protective devices. It uses a metal conductor as the fusible element connected in series in the circuit. When overload or short-circuit current passes through the fusible element, it melts due to its own heating, thereby breaking the circuit. The fuse has a simple structure and is easy to use. It is widely used in power systems, various electrical equipment, and household appliances as a protective device.

TRAFBER electrical component structure

The structure of the power cord is not very complex, but it cannot be simply understood from the surface. If you study the power cord carefully, some aspects require professional understanding of the power cord structure. The structure of the power cord mainly consists of an outer sheath, an inner sheath, and conductors. Common transmission conductors include copper and aluminum metal wires. (1) The outer sheath, also known as the protective sheath, is the outermost layer of the power cord. This outer sheath protects the power cord. The outer sheath has strong characteristics, such as high temperature resistance, low temperature resistance, resistance to natural light interference, good flexibility, long service life, and environmentally friendly materials. (2) The inner sheath, also known as the insulating sheath, is an indispensable intermediate structural part of the power cord. As the name suggests, the main function of the insulating sheath is insulation, ensuring the electrical safety of the power cord, preventing any leakage between the copper wires and the air. The material of the insulating sheath must be soft to ensure it fits well in the middle layer. (3) Copper wire is the core part of the power cord. Copper wire is mainly the carrier of current and voltage. The density of the copper wire directly affects the quality of the power cord. The material of the power cord is also an important factor in quality control. The quantity and flexibility of the copper wire are also factors to consider. (4) The inner sheath is a layer of material wrapped between the shielding layer and the wire core of the cable, generally made of polyvinyl chloride (PVC) plastic or polyethylene (PE) plastic. Low-smoke zero-halogen materials are also available. Used in accordance with process regulations to prevent the insulation layer from coming into contact with water, air, or other objects, avoiding moisture absorption and mechanical damage to the insulation layer.

A thermopile is a pyroelectric infrared sensor, a device composed of thermocouples. It is widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It is composed of two or more thermocouples connected in series, and the thermoelectric potentials output by each thermocouple are superimposed on each other. Used to measure small temperature differences or average temperatures. Structure of a thermopile: The radiation receiving surface is divided into several sections, each connected to a thermocouple. Connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made into fine-wire and thin-film types, as well as multi-channel and array devices.

TRAFBER electrical component features

LED lamp is a light-emitting diode (LED), which uses solid semiconductor chips as the light-emitting material. Compared with traditional lamps, LED lamps are energy-saving, environmentally friendly, and have good color rendering and response speed. (1) Energy saving is the most prominent feature of LED lamps in terms of energy consumption. The energy consumption of LED lamps is one-tenth that of incandescent lamps and one-quarter that of energy-saving lamps. This is the biggest feature of LED lamps. People now advocate energy conservation and environmental protection. It is precisely because of this energy-saving feature that LED lamps have a wide range of applications and are very popular. (2) Can operate in high-speed switching states. When we walk on the street, we find that every screen or image composed of LED is unpredictable. This indicates that LED lamps can perform high-speed switching operations. However, the incandescent lamps we usually use cannot achieve this working state. In daily life, if the switch is turned on and off too many times, it will directly lead to the breakage of the incandescent lamp filament. This is also an important reason why LED lamps are popular. (3) Environmental protection: LED lamps do not contain any heavy metal materials such as mercury, whereas fluorescent lamps do. This reflects the environmental protection feature of LED lamps. People now attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lamps. (4) Fast response speed is another prominent feature of LED lamps, meaning the reaction speed is relatively fast. As soon as the power is connected, the LED lamp lights up immediately. Compared with the energy-saving lamps we usually use, its response speed is faster. When turning on traditional bulbs, it often takes a long time to illuminate the room, and they only light up after the bulb has completely heated up. (5) Compared with other light sources, LED lamps are "cleaner". The so-called "cleanliness" does not refer to the cleanliness of the lamp surface and interior, but rather that this lamp is a cold light source, does not generate excessive heat, and does not attract insects that like light and heat. Especially in summer, there are many insects in rural areas. Some insects are naturally heat-loving. Incandescent lamps and energy-saving lamps generate heat after being used for a period of time. This heat is exactly what insects like, making it easy to attract them. This will undoubtedly bring many pollutants to the lamp surface, and insect excrement will make the indoor environment very dirty. However, LED lamps are cold light sources and do not attract insects, thus avoiding insect excrement. Therefore, LED lamps are "cleaner". Semiconductor light-emitting diodes have a wide range of applications, low power consumption, long service life, and are low-carbon and environmentally friendly. The application of semiconductor light-emitting diodes in China is very extensive. Many lighting devices in residential homes use semiconductor light-emitting diodes. Most street lights also use semiconductor light-emitting diode street lights as lighting sources. Some road lighting fixtures also combine solar technology, which can save a large amount of electrical energy. Photodiodes can be divided into gallium aluminum arsenide photodiodes, aluminum gallium phosphide arsenide photodiodes, gallium phosphide photodiodes, and aluminum arsenide photodiodes, depending on the material.
