slow blow fuse vs fast blow fuse.The difference and function of fuses and relays

　　　　A relay is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic regulation, safety protection, and conversion circuits in the circuit.　　The function of a fuse is to: when a circuit malfunctions or is abnormal, the current continuously increases, and the increased current may damage some important or valuable components in the circuit, or burn the circuit or even cause a fire. If the fuse is correctly installed in the circuit, the fuse will fuse and cut off the current when the current abnormally rises to a certain height and time, thereby protecting the safe operation of the circuit.　　The relay can be 'off' or 'on' through current control, that is, it can be reconnected after being disconnected, while the Shenzhen fuse needs to be replaced after being disconnected, and programs cannot be used to reconnect it.

The Application of Self Recovery Fuses in Disinfection Cupboards.30 amp screw in resettable fuse

　　　　Disinfection cabinets have been applied in public places such as hotels, restaurants, industrial canteens, Chinese and Western restaurants, and canteens of enterprises and institutions, and have gradually entered modern homes. Disinfection cabinets have gradually become an essential disinfection tool in daily life. While people value its practicality, its safety, reliability, and stability are also issues of concern.　　The disinfection methods for cupboards are mostly thermal infrared or ultraviolet. By driving infrared or ultraviolet emission tubes with high frequency and high voltage, this high-frequency and high voltage driving circuit is prone to burning out the driving transistor due to high current and temperature. This puts forward high requirements for the design of engineers. To ensure the reliability and safety of the circuit, it is necessary to design overcurrent and overheating protection circuits. Especially when there is no installed infrared emission tube or ultraviol

Definition of high-voltage fuse.mini cooper fuse box

　　　　ISO-8820 and QC/T420-2004 standards define it as a fused protective device connected to a circuit that disconnects the circuit when the current exceeds the specified value and time. A fuse is a thermal response device, and the fuse or fuse in the fuse is made of a fusible alloy with high resistivity or a good conductor with a smaller cross-sectional area. In order to protect the wiring harness and other equipment, it is intentionally designed and manufactured as the weakest part of the circuit. Under normal working conditions, the fuse or fuse in the fuse will not blow; When a short circuit or severe overload occurs in the system, the fuse or fuse will immediately melt, thus protecting the circuit and electrical equipment　　In order to ensure the safe operation of the vehicle's electrical appliances and ensure the proper function of the fuse, it is particularly important to choose the appropriate type and specification. The selection of fuses involves the following factors: current

waterproof fuse block.Why do fuses have high resistivity

　　　　A fuse is a wire made of lead antimony alloy with a lower melting point and a lower resistivity. The more voltage constant resistance can be compared, the more it can detect micro current resistance that exceeds the working range. A high current is required to fuse the resistance, which can burn out the electrical appliance and prevent it from melting. Some principles use the current thermal effect fuse to control the current flow and allow the current to flow. According to the formula Q=IRT, the resistance produces more heat and is easier to fuse for safety and protection. It has a certain relationship with Joule's law, but things in life are not so simple. Fuses cannot be too large or small. If they are too large, they can easily burn down household wires and even cause fires. If they are too small, they can easily fuse and cause unnecessary trouble.　　A fuse can directly see the principle of a wire. The rated current of a fuse is the same as that of a wire. Even if it can be seen

Working principle of fuses

　　　　When current flows through a conductor, it will generate heat due to the presence of a certain resistance in the conductor. And the calorific value follows this formula: Q=0.24I2RT; Where Q is the heat generated, 0.24 is a constant, I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time for the current to flow through the conductor; Based on this formula, we can easily see the simple working principle of a fuse. When the material and shape of the fuse are determined, its resistance R is relatively determined (without considering its resistance temperature coefficient). When an electric current flows through it, it generates heat, and as time increases, its heat also increases. The magnitude of current and resistance determines the rate of heat generation, while the construction and installation of a fuse determine the rate of heat dissipation. If the rate of heat generation is less than the rate of heat dissipation, the fuse will not
