　　Basic knowledge and common fuse specifications of fuse wire base fuses

　　In many electronic devices, fuses are indispensable. Since Edison invented the

　　After the first plug-in fuse with a thin wire enclosed in the lamp holder, there are more and more types of fuses and their applications are becoming more and more widespread. Here are some common knowledge on fuse parameters, selection, and application.

　　The rated values and performance indicators of fuses are determined based on laboratory conditions and acceptance specifications. There are multiple authoritative testing and appraisal institutions internationally, such as UL certification from Underwriters Laboratories in the United States, CSA certification from the Canadian Standards Association, MTTI certification from the Japan Department of International Trade and Industry, and ICE certification from the International Electrotechnical Commission. The selection of fuses involves the following factors: 1. Normal operating current.home energy storage system battery

　　2. The applied voltage applied to the fuse.

　　3. Abnormal current that requires the fuse to be disconnected.

　　4. Short and long periods of abnormal current are allowed.

　　5. The ambient temperature of the fuse.

　　6. Pulse, impulse current, surge current, starting current, and circuit transient values.

　　7. Are there any special requirements that exceed the fuse specifications.

　　8. Dimensional limitations for installation structures.

　　9. Required certification body.

　　10. Fuse holder components: fuse clip, installation box, panel installation, etc. Below are some explanations of common parameters and terminology in fuse selection.

outboard motor thermostat stuck open.What is the overcurrent protection principle of self restoring fuse PTC?

　　　　Due to the characteristic of instantaneous resistance jump, this type of PTC is often used for overcurrent protection in electrical products. We know that for a conductor, its resistance value is R. When the current flowing through the conductor is I and the duration is t, the heat generated by the conductor Q can be calculated using Joule's law: Q=I ^ 2 * R * t. It can be seen that the heat generated by the conductor is proportional to the square of the current flowing through the conductor I, that is, as long as the current increases a little, the heat generated Q will sharply increase. During normal operation, due to the small working current IH, the heat generated by the current flowing through PTC is not sufficient to reach the Curie point. PTC has always shown a zero power resistance Rmin at the factory, usually at the milliohm level (specific data varies depending on the PTC series), which is equivalent to the closed state of a switch. Once the current flowing through PTC It

plug in mcb for old fuse box.Working principle of self recovery fuse

　　　　The polymer overcurrent protection element is made of polymer materials with conductive particles added. The basic principle is an energy balance: when the current flows through the component, heat is generated due to the power consumption of the current, and some of the generated heat is dispersed and sent to the environment, while others increase the temperature of the polymer material. At the corresponding working current, the heat generated by the component and the heat dissipated reach a balance, and the current can pass through normally. When excessive current is generated, the component rapidly generates heat that cannot be dissipated in a timely manner, resulting in an increase in the temperature of the polymer material inside the component. When the temperature reaches the crystallization and melting temperature of the material, the polymer material rapidly expands, blocking the conductive path composed of conductive particles, resulting in a rapid increase in electrical r

　　The protective effect of PPTC mainly relies on the following aspects　　1. Material characteristics: The material used in PPTC is a polymer composite material that has a certain degree of conductivity and can normally allow current to pass through. However, when overheating occurs, the volume of the material rapidly expands, causing the polymer to melt and interact with the conductive filler, resulting in instantaneous high resistance. This feature enables PPTC to quickly cut off current and provide protection.　　2. Thermal sensitivity: The material of PPTC has thermal sensitivity, and when current passes through PPTC, the material will generate heat due to resistance. When the current is too high, the temperature of the material will increase. When it reaches a certain threshold, the material will undergo a change in phase transition properties, which will quickly cause an increase in resistance. This thermal sensitive characteristic enables PPTC to respond promptly and quickly cut off

　　Four elements to avoid when using self recovering fuses (PPTC)　　One: Avoid the significant mechanical stress of self recovering fuse chips　　Fuses will undergo thermal expansion of the polymer itself during operation. If under certain mounting conditions, the two ends of the device chip are subjected to significant pressure, compression, distortion, bending, etc., the thermal expansion phenomenon will be limited, thereby affecting the electrical function of the device, which will cause the protective device to be unable to operate under fault conditions.　　Secondly, to avoid short circuits in non packaged devices　　Is there any conductive object contamination between the edge of the self-healing fuse device and the bracket when using a non encapsulated PPTC device. This non encapsulated conductive object pollutant can cause faults such as oxidation and combustion.　　Thirdly, several points to pay attention to when soldering components　　When wave soldering or reflow soldering is required,

It adopts a square shell design and triggers the cut-off of current through temperature changes. Its innovative shape makes it more convenient to apply in compact spaces.　　2、 Advantages of Square Temperature Fuses　　Innovative design: The square temperature fuse adopts a square shell design, which is more compact than traditional cylindrical fuses and can save valuable circuit board space.　　High temperature triggering: Square temperature fuses have sensitive temperature triggering characteristics.
