This article will introduce in detail a new type of circuit protection component - self recovering fuse. By analyzing its working principle, characteristics, and application areas, we aim to provide you with a comprehensive understanding of this innovative fuse. 1. Principle and characteristics of self recovering fuses Self recovery fuse is a type of fuse with overload protection function, whose main principle is to quickly cut off the current when it exceeds the rated value to prevent equipment from overheating or damage. After the current returns to normal, the self recovering fuse will automatically return to its normal working state without manual intervention. Compared with traditional fuses, self-healing fuses have the following characteristics: a. Self recovery function: Onc
The selection of self recovery fuses should pay attention to the following parameters 1. Rated zero power resistor: PPTC thermistors should be packaged in stages according to zero power resistors, and the resistance range should be indicated on the outer packaging. After the withstand voltage and current capacity tests, the range of resistance change rate in each group of samples before themselves, δ | Ri after - Ri before/Ri before - (Rj after - Rj before)/Rj before |, is ≤ 100%. 2. PTC effect: PTC effect refers to the fact that the resistance of certain materials increases with temperature. In self-healing fuses, PTC effect can improve the protection capability of the circuit. 3.

A considerable number of types of conductive polymers will exhibit this e
How to correctly select self recovering fuses to ensure optimal protection for circuits When choosing a self recovery fuse, the following parameters need to be considered: maximum operating environment temperature, standard operating current, maximum operating voltage, and maximum fault current. To adapt to the maximum ambient temperature and standard operating current of the circuit, a temperature reduction meter can be used to select the most suitable component. At the same time, it is necessary to compare the maximum electrical rating of the selected component with the maximum operating voltage and fault current of the circuit to ensure that it can withstand the maximum operating voltage and fault current of the circuit. In addition, determining the action time of the self-healing fuse is also very important. Action time refers to the amount of time it takes to switch the component to a high resistance state when a fault current occurs throughout the entire device. In order to p
Classification of fuses There are various ways to classify fuses, and the following are common classifications: Classified by structural form Plug in fuse: This type of fuse has a simple structure and is usually composed of a porcelain base and a plug. There is a fuse installed on the plugin, and when the fuse is blown, the plugin can be easily removed for replacement. It is mainly used in circuits with low current and low voltage, such as home lighting circuits. Spiral fuse: It consists of a ceramic cap, fuse tube, and base. The melting tube is equipped with a fuse, which can be installed on or removed from the base by rotating the ceramic cap. The advantage of this type of fuse is that it is relatively easy to replace the fuse, and after the fuse inside the fuse tube is blown, there will be a clear indication, which is convenient for detecting faults. It is suitable for small and medium-sized circuits, such as control circuits for electric motors. Enclosed fuse: The fuse of th
Fuse resistance In addition to protecting the circuit, fuses themselves also have a certain resistance in the circuit. From the essence of resistance, the resistance of a fuse is determined by factors such as the conductivity, length, and cross-sectional area of its material. Generally speaking, the resistance of a fuse is relatively small, so that when normal current passes through, the voltage drop generated at both ends is small and will not have a significant impact on the normal operation of the circuit. In terms of materials, the resistivity of different materials varies. For example, the resistivity of materials such as lead tin alloys mentioned earlier determines the size of the fuse resistance. If it is a material with high electrical resistivity, the resistance of the fuse will be higher at the same length and cross-sectional area. From the perspective of length factor analysis, according to the law of resistance, under the same material and cross-sectional area, the lo
Is the fuse made of aluminum Fuses are not necessarily made of aluminum. The material selection of fuses depends on various factors, including their role in the circuit, required melting characteristics, and cost. Although aluminum is a common metal material, it is not commonly used in the manufacture of fuses. Aluminum has some characteristics, such as good conductivity and relatively low cost. However, aluminum also has some shortcomings, making it less suitable as the main material for fuses. Firstly, the melting point of aluminum is relatively high, around 660 ℃. This means that when overcurrent occurs in the circuit, aluminum fuses may take a long time to melt, making it difficult to protect the circuit and equipment in a timely and effective manner. Secondly, aluminum may generate large arcs during the melting process, which may cause damage to surrounding circuit components. In addition, aluminum has a fast oxidation rate and is prone to forming an oxide film on its surface
How to measure the quality of a fuse Judging the quality of a fuse is an important step in ensuring the normal operation of a circuit. Here are several common methods for detecting the quality of fuses. 1、 Visual inspection method Firstly, the quality of the fuse can be preliminarily judged by visually inspecting its appearance. Observe whether there are any signs of breakage or burning on the glass or ceramic tube of the fuse. If the outer shell of the fuse is damaged, it may indicate that the internal metal wire has blown or been damaged. At the same time, check whether the two ends of the fuse are firmly connected, whether there is any looseness or oxidation phenomenon. If the connection is poor, it may also affect the normal operation of the fuse. 2、 Resistance measurement method The resistance range of a multimeter can be used to measure the resistance value of a fuse. For a normal fuse, its resistance value should be very small, close to zero. If the measured resistance va
What metal is a fuse A fuse is an important component that plays a protective role in a circuit, usually made of a specific metal or alloy. Common fuse materials mainly include low melting point metals such as lead tin alloy and zinc. Lead tin alloy is a widely used fuse material with a low melting point, generally between 183 ℃ and 232 ℃. When the current in the circuit exceeds the rated current of the fuse, the fuse will melt due to temperature rise, thereby cutting off the circuit and protecting electrical equipment and circuits from damage caused by excessive current. The advantages of lead tin alloy are its relatively stable melting point and low cost. At the same time, its conductivity is also good, allowing current to pass through under normal working conditions and quickly melting under abnormal conditions. In addition to lead tin alloy, zinc is also a commonly used fuse material. The melting point of zinc is about 419.5 ℃, which is relatively high. But in specific circuit
