　　　　According to temperature, it can be divided into: 73 degrees 99 degrees 77 degrees 94 degrees 113 degrees 121 degrees 133 degrees 142 degrees 157 degrees 172 degrees 192 degrees 216 degrees 227 degrees 240 degrees 70 degrees 77 degrees 84 degrees 92 degrees 95 degrees 105 degrees 110 degrees 115 degrees 121 degrees 128 degrees 130 degrees 139 degrees 141 degrees 144 degrees 152 degrees 157 degrees 169 degrees 184 degrees 185 degrees 192 degrees 216 degrees 227 degrees 228 degrees 240 degrees 250 degrees 280 degrees 320 degrees　　Due to the certain overload capacity of various electrical equipment, it is allowed to operate for a long time under certain conditions; When the load exceeds the allowable value, it is required to protect the melt from melting within a certain period of time. Some devices have a high starting current but a short starting time, so it is required that the protective characteristics of these devices should meet the needs of equipment operation. It is required

The Protection Application of Self Recovery Fuses in Sweepers.mini cooper fuse box symbols meaning

　　　　With the rapid development of modern technology, a large number of products can only be integrated into our daily lives, and the broom is one of them. As a smart home product, floor sweepers are not uncommon in first tier cities in China. The working principle of a floor sweeper is not too difficult to understand, mainly relying on the drive of internal small motors to provide power. Due to unstable voltage or jamming during operation, the motor may encounter problems such as rotor blockage, overload, or even burning out. So the internal motor must be designed with corresponding protection circuits to ensure its reliability and stability of operation.　　There are many types of protection methods for small motors inside the sweeping machine. Previously, bimetallic temperature controllers were commonly used. When the motor was working, if the coil temperature increased, the circuit would be disconnected, and after the temperature decreased, it would be connected again. However, this m

Fuse melt rating.motor blows fuse on startup

　　　　The rated current of the melt is not equal to the rated current of the fuse. The rated current of the melt is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the melt and determined in conjunction with the main electrical appliance.　　The fuse is mainly composed of three parts: the melt, the shell, and the support, among which the melt is a key component that controls the fusing characteristics. The material, size, and shape of the melt determine the fusing characteristics. Melt materials are divided into two categories: low melting point and high melting point. Low melting point materials such as lead and lead alloys have a low melting point and are prone to melting. Due to their high electrical resistivity, the cross-sectional size of the melt produced is larger, and the metal vapor generated during melting is more. They are only suitable for fuses with low breaking capacity. High melting poin

Wiring method of fuse holder

　　　　The wiring methods of fuse holders mainly include plug-in wiring and threaded wiring. Plug and play wiring refers to inserting wires into the socket inside the fuse holder and clamping them with spring plates to achieve wiring; Screw type wiring is the process of threading wires into threaded holes in the fuse holder and connecting them through the frictional force of the threads. Below, we will introduce these two wiring methods separately.　　Plug and drop wiring is a common fuse holder wiring method. It has the advantages of simple wiring and convenient installation, and is suitable for application scenarios with smaller wire sizes. The spring plate of plug-in wiring needs to ensure sufficient force and reliability when clamping the wire. According to statistics, fuse holders with plug-in connections have a slightly higher electrical failure rate than fuse holders with threaded connections, but their prices are cheaper. The plug-in fuse holder is suitable for low voltage and low c

tv fuse replacement cost.Basic Knowledge of Chip Fuses

　　　　Firstly, understand the function of fuses: Place the circuit fuse correctly. Then, the fuse will rise to a certain height and after a certain period of time, the fuse will cut off the current, thus protecting the operation of the circuit. The principle of patch fuses is the same, but the style is different. Below, we will have a detailed understanding:　　Chip fuses are mainly used in electronic products such as digital cameras, laptops, and smartphones. Due to differences in product technology, the selection focus varies from traditional glass tube fuses to micro fuses and chip fuses. The selection of chip fuses involves the following factors:　　The normal operating current of the circuit. The working current through the fuse should not exceed 70% of the rated current of the fuse.　　Pulse, surge current, surge current, starting current, and circuit transient. Chip fuses pay special attention to the following facts: due to the small process size, the impact resistance of chip fuses is
