Fuses, also known as current fuses, are defined as "fuse links" in the IEC127 standard. It mainly serves as overload protection. If the fuse is correctly placed in the circuit, the Shenzhen fuse will fuse and cut off the current when the current abnormally rises to a certain height and heat, protecting the safe operation of the circuit. More than a hundred years ago, the fuse invented by Edison was used to protect expensive incandescent lamps at that time. With the development of the times, the fuse protected electrical equipment from overheating and prevented serious damage caused by internal faults in electronic equipment.
First, you need to understand the working principle of silk preservation. After being powered on, the heat converted from electrical energy causes the temperature of the soluble substance to rise. normal When the working current or the allowable current passes through me. The heat generated is related to the radiation, convection, and conduction of the melt and shell through the surrounding environment Gradually balance the heat generated and dissipated. When working abnormally, the heat generated is greater than the heat dissipated, and the excess heat will Gradually gathering on the melt, when the temperature reaches or exceeds the melting point of the melt, it will cause the melt to melt, cut off the current, and The function of the safety protection circuit. To purchase alkali resistant silk, it is necessary to understand some parameters of alkali resistant silk: 1. Constant current - In: The rated current of a fuse is the maximum current value that a circuit can operate.
In fact, a fuse is called a fuse. It can be said that a fuse is a fuse, and a fuse may not necessarily be equivalent to a fuse. A fuse is a finished electronic component, but a fuse can be a semi-finished product, that is, an electronic component that has not been formed. Therefore, I usually label the reason for the fuse on the product catalog instead of the fuse. Fuses represent a smaller range, while fuses represent a larger range. There are many types of fuses, but fuses are a single material. There are currently two types of Shenzhen fuses on the market. One is through overcurrent protection circuit, and the other is through temperature protection circuit. Either way, it can cut off the power supply in a timely manner to protect our equipment in case of circuit failure. A fuse is a fuse, commonly known as a fuse, and a fuse is a standard name. Glass tubes or flexible wires are commonly referred to as fuses, but fuses are more complex in structure than fuses. If there is an i
A fuse refers to a self destructing fuse that experiences significant surges or other current exceeding limits in a circuit; In order to protect the components of other parts of the circuit where the fuse is located and the equipment is normal, the cost of replacing the fuse can be ignored compared to replacing the entire circuit that may be damaged. Due to the fact that fuses are a common element that needs to be replaced, we will introduce two basic concepts and provide a more in-depth introduction to fusion applications and testing and diagnostic methods. Please refer to the relevant articles on the website. Common Sense 1: Determine if the fuse is burning (fuse)? If the fuse can be removed from the circuit, it can be a visual Shenzhen fuse to determine whether it has burned out; The simplest method to determine whether a fuse is a continuity test is to blow other materials. Quickly test with a multimeter to determine if it is working properly, by hearing a beep and touching t
1、 The function of a fuse: 1. Under normal circumstances, fuses play a connecting role in the circuit. 2. Under abnormal (overload) conditions, the fuse serves as a safety protection component in the circuit, which can safely cut off and protect the circuit through its own fusing. 2、 The working principle of a fuse: When a fuse is energized, the heat converted from electrical energy causes the temperature of the melt to rise. Normal working current or allowable When a certain overload current passes through, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat dissipated through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the melt temperature can increase; When the temperature reaches or exceeds the melting point of the melt, the melt melts, fuses, and cuts off the current, playing a role in safety protection of the circu
1. Rated current: The working current of a fuse (the maximum current that a fuse can maintain normal operation for a long time under normal conditions). 2. Rated voltage: The working voltage of the fuse (the maximum voltage that the fuse can safely withstand at the moment of disconnection). When selecting a fuse, the rated voltage should be greater than the input voltage of the protected circuit. 3. Breaking capacity: When a large overload current (such as a strong short circuit) occurs in a circuit, the fuse can safely cut off (break) the maximum current of the circuit. It is an important safety indicator for fuses. Safe breaking refers to the phenomenon of avoiding splashing, burning, explosion, and other hazards to surrounding components, components, and even personal safety in the breaking circuit. 4. Overload capacity (carrying capacity): The maximum overload current that a fuse can maintain for a specified period of time. UL standard stipulates that the maximum non fusing c
