　　1. Replace with a suitable fuse model

　　Don't rush when a fuse malfunctions. Disconnect the circuit first, eliminate the problem, and then replace it with a new one. The quality and model of the new fuse must meet the specified range of the circuit.

　　2. Perform an overload test on the fuse

　　Conducting overload testing on fuses can effectively detect the quality of the fuses and select appropriate fuse models. After being tested on the machine and found to be fine, they can be installed and used.

　　Can the fuse still be used after the circuit is overloaded?

　　Answer: Whether the fuse can still be used after the circuit is overloaded depends on the type of fuse you installed in the circuit. If a disposable fuse is used in the installation circuit and the fuse blows after the circuit is overloaded, a new fuse needs to be replaced. If a self restoring fuse is used, the fuse will automatically block excessive current in the event of overload. After troubleshooting, the fuse can automatically recover and connect the circuit after a period of time.

The Importance of Fuses.fast blow fuse characteristics

　　　　A fuse is an electrical component installed in a circuit to ensure safe operation of the circuit. When the circuit malfunctions or is abnormal, it may burn the circuit or even cause a fire. Some fuses have a blown indicator device, which is used to indicate that when the fuse is activated (blown), it undergoes a certain appearance change and is easily detected by maintenance personnel. So what are the components of a fuse?　　1. Electrode　　Usually, there are two important components that are connected between the melt and the circuit. They need to have good conductivity and should not generate significant installation contact resistance.　　2. Melt　　It is the core of a fuse and plays a role in cutting off the current when it is blown. Fuses of the same type and specification should have the same material, geometric dimensions, and resistance values as small and consistent as possible. It is important to have consistent fusing characteristics.　　3. Bracket　　The melt of a fuse is generall

　　　　Self recovery fuse is a type of overcurrent electronic protection component, which is made by mixing conductive particle materials with polymer organic polymers under high pressure, high temperature, and vulcanization reaction conditions, and processed through special processes. What are the standard requirements for self restoring fuse technology? 1. The rated zero power resistance PPTC thermistor should be packaged in different levels according to the zero power resistance, and the resistance range should be indicated on the outer packaging. After the withstand voltage and current resistance tests, the change rate of the resistance before each group of samples is extremely poor δ| After Ri - Before Ri - (After Rj - Before Rj)/Before Rj|　　2. The PTC effect refers to a material with a Positive Temperature Coefficient (PTC) effect, which means that the resistance of the material increases with increasing temperature. Most metal materials have the PTC effect. In these materials, the

　　　　1. When the melt melts, it is necessary to carefully analyze the reasons for the melting, which may include:　　(1) Normal fusing due to short circuit fault or overload operation;　　(2) If the melt is used for too long, it may break due to oxidation or high temperature during operation, resulting in changes in the characteristics of the melt;　　(3) There is mechanical damage during the installation of the melt, which reduces its cross-sectional area and causes accidental disconnection during operation.　　2. When replacing the melt, it is required to:　　(1) Before installing a new melt, it is necessary to identify the cause of melt melting. If the cause of melting is not determined, do not replace the melt for trial delivery;　　(2) When replacing a new melt, check whether the rated value of the melt matches the protected equipment;　　(3) When replacing a new melt, it is necessary to check the internal burn condition of the fuse tube.

tv fuse blows when plugged in.The impact of fuse aging on usage

　　　　After the fuse ages, there is no danger of generating the current that should be cut off and the fuse not blowing. The aging of a fuse is equivalent to a decrease in the rated value (current) rather than an increase, resulting in the circuit being cut off at a small overload current or pulse.　　The durability test in the IEC standard is the life test, which is conducted using a DC power supply at normal temperature:　　a. Measure the voltage drop until the temperature stabilizes;　　b. 1.2 times the rated current for 1 hour and cut off the current for 15 minutes. Cycle 100 times;　　c. Measure the voltage drop after powering on for 1.5 In for 1 hour;　　d. Measure the voltage drop using the same method as A.　　Requirement: The voltage drop change before and after the test should not exceed 10%, and the identification should still be clear and distinguishable. There should be no deterioration in the end cap solder joints.
