　　Fuses are mainly used as basic protective devices for preventing short circuit faults in household appliances. They are generally equipped and selected based on the current of the household appliance. This can be simply calculated by considering current=(power ÷ voltage)&TIMes; 1.5, for example, electrical equipment current=1 kW ÷ 220 V&TImes; 1.5=6.8A, you can choose fuses 6-8A.

　　The fusing current of a fuse is usually 1.5-2.0 times the rated current. If the total power of each household appliance exceeds 1100 watts during normal electricity use in a household, choose a 5-ampere fuse and use a No. 20 fuse with a diameter of 0.98 millimeters. When the current exceeds 7.5 amperes to 10 amperes, the fuse will automatically blow to achieve protection.

　　SMD fuses are made of lead antimony alloy with high resistivity and low melting point. Its function is to generate more heat when there is too much current in the circuit, causing its temperature to reach the melting point, thereby fusing and automatically cutting off the circuit, playing a safe role.

　　Functional parameters of plastic encapsulated patch varistors　　1. Rated voltage (Ur): refers to the highest voltage that PPTC can withstand, usually expressed in volts (V), such as Ur=24V.　　2. Power outage current (IH): refers to the current that cuts off the circuit when the temperature of the PPTC rises at rated voltage, usually expressed in amperes (A), such as IH=1A.　　3. Trigger current (IT): Refers to the current at which PPTC begins to respond, that is, when the current gradually increases to a certain value, PPTC will begin to reduce resistance, usually expressed in milliampere (mA), such as IT=100mA.　　4. Zero current resistance (Ro): refers to the resistance value of a circuit passing through PPTC when it is in a normal state, usually expressed in ohms (Ω), such as Ro=40 Ω.　　5. Maximum current (Imax): refers to the maximum current that PPTC can pass through, usually expressed in amperes (A), such as Imax=3A.　　6.

　　High voltage fuses　　High voltage fuses play a crucial protective role in high-voltage power systems.　　High voltage fuses are mainly used to protect high-voltage electrical equipment and lines, preventing equipment damage and power system accidents caused by overcurrent, short circuit and other faults. It is usually made of special materials that can withstand the impact of high voltage and high current.　　The working principle of high-voltage fuses is similar to that of ordinary fuses. When the current in the circuit exceeds its rated value, the fuse will melt and cut off the circuit. However, due to the particularity of high-voltage circuits, the design and manufacturing requirements for high-voltage fuses are higher. It needs to have good insulation performance, high melting point, high heat resistance, and high mechanical strength.　　The selection of high-voltage fuses is crucial in high-voltage power systems. Suitable fuses need to be selected based on parameters such as voltage le

air conditioner fuse box replacement.Is polymer PTC thermistor used for over temperature control?

　　Is polymer PTC thermistor used for over temperature control?　　Currently, polymer PTC thermistors are mainly used for overcurrent protection, and many polymer PTC thermistors have been successfully used for over temperature protection. This product allows battery pack designers to save some of the over temperature protection devices in their designs.　　Regarding the protection principle of polymer PTC thermistors, first we need to understand the materials used in their production and their composition.　　Polymer PTC thermistor is made of polymer material filled with carbon black particles. The characteristic of carbon black particles is that they have a conductive function, so they can pass the rated current.　　If the current flowing through a thermistor is too high during operation, its heating power will be greater than its heat dissipation power. At this time, the temperature of the thermistor will continue to rise, and at the same time, the collective in the thermistor will begin to

　　Working principle of fuse　　1、 Working principle of fuse　　When the fuse is powered on, the heat converted from electrical energy increases the temperature of the fusible item. When passing through normal operating current or allowable overload current, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat generated by convection, conduction, etc. gradually balances with the generated heat. If the generated heat is greater than the dissipated heat, the excess heat will gradually accumulate on the meltable object, causing its temperature to rise; When the temperature reaches and exceeds the melting point of the meltable material, it will melt, melt, and cut off the current, playing a role in protecting the circuit.　　2、 Terminology of fuses　　Rated current: The nominal operating current of the fuse tube (the maximum current that the fuse can maintain normal operation for a long time under normal conditions).　　Rated voltage: The nominal oper

　　How to Detect the Quality of SMD Fuses　　Detecting the quality of a surface mount device (SMD) fuse is crucial for ensuring the safety and proper functioning of electronic circuits. One common method is through visual inspection. Look for any signs of physical damage such as cracks, burns, or deformations on the body of the fuse. If the fuse casing appears damaged, it may have been subjected to excessive current or heat and is likely to be defective.　　Another way is to use a multimeter. Set the multimeter to the resistance measurement mode. A good SMD fuse should have a very low resistance value when in its normal state. If the measured resistance is extremely high or shows an open circuit, it indicates that the fuse has blown and is no longer conducting electricity as it should. However, if the resistance reading is within the acceptable range for that particular fuse type, it may still be in good working condition.　　It's also important to check the fuse's specifications and
