A temperature fuse is a circuit breaker that uses the heat generated by itself to melt the melt after the current exceeds a specified value for a period of time, thereby causing the circuit to disconnect; A current protector made using this principle. Fuses are widely used in high and low voltage distribution systems, control systems, and electrical equipment. As short circuit and overcurrent protectors, they are one of the most commonly used protective devices. A fuse is an overcurrent protector. The fuse mainly consists of parts such as melt, melt tube, and external filler. When in use, the fuse is connected in series to the protected circuit. When the current of the protected circuit exceeds the specified value and after a certain period of time, the heat generated by the melt itself fuses the melt, causing the circuit to disconnect, thus playing a protective role. Electrical appliances that use metal conductors as the melt to break the circuit are connected in series in the ci
Plug-in fuse The plug-in fuse can be divided into: ultra small plug-in fuse, small car fuse, medium car fuse, and large car fuse. The rated current ranges from 1-40 amperes (A) to larger sizes of 30-120 amperes (A), and the rated voltage is 32 volts (V). Fork bolt fuse The fork bolt type fuse can be divided into: small fork bolt type fuse and large fork bolt type fuse. The rated current ranges from 30-150 amperes (A) to large sizes of 40-800 amperes (A), and the rated voltage is 32/125 volts (V). Car glass tube fuse Car glass tube fuse can be divided into: 6.35 × 30mm glass tube fuse, 6.35 × 31.75mm glass tube fuse, 10 × 38mm glass tube fuse. The rated current ranges from 0.5 to 20 amperes (A) to 10 × 38mm20-80 amperes (A), rated voltage 32 volts (V).
If any electrical equipment does not work during the use of the car, it may be caused by a burnt fuse and needs to be replaced in a timely manner. The method is: 1. Turn off the ignition switch and open the fuse box cover. 2. Replace the fuse. Precautions: (1) Replace the fuse according to the rated current value indicated on the fuse box cover, and do not use a fuse with a higher rated current. (2) If the new fuse immediately blows again, it indicates that there may be a malfunction in the circuit system and should be repaired as soon as possible. (3) In the absence of backup fuses. In case of emergency, fuses on other equipment that have no impact on driving and safety can be replaced. (4) If a fuse with the same current load cannot be found, a lower rated current than the original fuse can be used instead.
1. When operating at a normal operating current of 25 ℃, the current rating of the fuse should usually be reduced by 25% to avoid harmful blowing. Most traditional fuses use materials with lower melting temperatures. Therefore, this type of fuse is relatively sensitive to changes in ambient temperature. For example, a fuse with a current rating of 10A is usually not recommended to operate at an ambient temperature of 25 ℃ and a current greater than 7-5A. 2. The voltage rating of the fuse must be equal to or greater than the effective circuit voltage. The general standard voltage rating series are 32V, 125V, 250V, and 600V. 3. The resistance of a resistor fuse is not important in the entire circuit. Since the resistance of a fuse with an amperage less than 1 is only a few ohms, this problem should be considered when using a fuse in a low-voltage circuit. Most fuses are made of materials with a positive temperature coefficient, so there are two types of resistors: cold resistance a
(Thermal Links), also known as: Temperature Control; It is a disposable element connected to the circuit with a very accurate and reliable temperature protection circuit. When the working environment temperature exceeds the rated temperature of the Thermal cutoff, the chemical heat sensitive bean in it will generate high temperature and quickly interrupt the circuit, avoiding the harm caused by overheating. After the temperature control fuse blows, it is necessary to manually replace it with a new one to restore normal operation of the circuit. Temperature control fuses are widely used in: microwave ovens, Water dispenser, disinfection cabinets, electric irons, toasters, barbecue machines, coffee makers, kettles, dryers, refrigerators, electric water heaters and other electrical equipment. The Thermal cutoff has the function of detecting abnormal temperature and cutting off the circuit. It can detect abnormal temperature rise of household or industrial electrical products and qui
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. If there are severe burns, the fuse tube should be replac
