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 automatical
There are many types of fuses, including classification by protection form, scope of use, volume, rated voltage, breaking capacity, and fusing speed. Below is an introduction to the classification by type, which can be divided into: current fuses: patch fuses, miniature fuses, plug-in fuses, and tubular fuses; Temperature fuse: RH square type, RP resistance type, RY metal case; Self recovery fuse: plug-in, laminated, patch. 1、 Current fuse Chip fuse. There are specifications such as 0805 and 1206, which use thin film technology to accurately control electrical characteristics. Due to its small size, it is an ideal choice for providing secondary protection for circuits in space limited applications, such as handheld portable electronic devices and various instruments and meters. Insert a fuse. Commonly seen in automotive applications, sometimes also known as fork bolt fuses Tubular fuse. This is very common, especially in various power supply applications such as switching powe
If the fuse can be removed from the circuit, it can be a visual 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 the wires together, or seeing a 0 ohm reading. After confirming that the circuit power is turned off, place the leads at both ends of the fuse. If you hear the same beep and the resistance reading of the multimeter is very low, then the fuse will not blow. If you don't hear the beep and the meter reading is OL, the fuse will blow. Take reasonable preventive measures to stay away from dangerous voltages. Supply the power circuit and switch to the multimeter voltage measurement mode. Ensure that DC circuits are selected for DC and AC circuits are selected for AC Connect the multimeter leads on both sides of the fuse. If the indicated voltage is small or even not, the fuse is intact
In order to enable a broader participation of low-voltage electrical appliance professionals in standardization work, to understand standardization policies and trends, the National Low-Voltage Electrical Appliance Standards Committee is organizing a series of events for the 2023 Annual Standardization Conference and Low-Voltage Electrical Appliance Technology Conference from September 24th to 26th in XIAN. In 2023, under the leadership of the higher authorities and the joint efforts of various committee members, the National Low-Voltage Electrical Appliance Standards Committee actively organized and carried out various standardization activities, achieving fruitful results: earnestly implementing the National Standardization Development Outline, in accordance with the new version of the "National Standard Management Measures," focusing on the construction of the new standard system for distribution and utilization of electrical equipment and systems, and emphasizing the research
Self restoring fuses are a common circuit protection component in our daily lives. For commonly used air conditioners, there is a self recovery fuse used to control circuit board overcurrent, overload, and overheating protection. The self restoring fuse is composed of high-tech polymer resin and nano conductive grains through a special process. Under normal circumstances, conductive grains form a chain like conductive path with resin connections, and the self recovery fuse operates normally; When an abnormal current is generated due to a circuit malfunction, the conductive path is disconnected, and the PTC resistance rapidly increases to limit the abnormal current, thereby protecting the precision components in the circuit from damage; After troubleshooting, the PTC returns to a low resistance state without the need for manual replacement, and the circuit returns to normal operation. Due to its advantages such as long lifespan, sensitive response, small size, and simple installati
The fusing current of the fuse should be between the rated current of the teaching equipment and the high current, so as to ensure that the enterprise equipment can be managed and operated normally. Turn off when the power approaches high current in a timely manner. Rated current refers to the current that an electrical appliance operates at rated voltage, which refers to the large current that students are allowed to pass through for a long time under the development conditions of rated voltage management work under different temperatures of the reference environment, and the heating temperature does not exceed the allowable temperature for long-term heating of the enterprise. High current refers to a limit of current that can be sustained without affecting equipment safety. It is generally only allowed to occur for a short period of time, otherwise it may cause equipment damage. The operating current of the motor can operate for a long time, usually at most about times the rated
