Water heater temperature fuse failure

The temperature fuse of the water heater is a very important part, it can ensure that the temperature of the water heater is within a safe range, and avoid safety problems caused by excessive temperature. However, there is also the possibility of failure in the fuse, and the failure of the temperature fuse of the water heater will have a certain impact on the normal use of the water heater. First, the reasons for the failure of the water heater temperature fuse: 1. Overload work: During long-term work, if the working current of the water heater exceeds the carrying capacity of the fuse, the fuse will be damaged. 2. The temperature is too high: If the temperature of the water heater is too high, it may also cause damage to the fuse. 3. Expiration of service life: The temperature fuse of the water heater also has a service life. When it is used for too long, the fuse will lose its effect and malfunction. Second, the performance of the water heater temperature fuse failure 1. The water heater cannot heat normally: If the fuse fails, the water heater cannot heat normally, or even fail to work. 2. The temperature of the water heater is too high or too low: After the fuse fails, the temperature of the water heater cannot be controlled, and the temperature may be too high or too low. 3. Short circuit of the water heater: If the fuse is short circuited, it will cause a short circuit of the electrical appliances, which may cause fire and other dangers. Third, the treatment method of the temperature fuse of the water heater 1. Replace the fuse: If the fuse fails, you need to replace it with a new one. Pay attention to choosing the fuse that suits your water heater.

What are the types of thermal fuses? How to use the thermal fuse correctly

The main function of the thermal fuse is to protect the circuit. Once the temperature of the electrical equipment exceeds the rated temperature of the fuse itself, it will automatically melt and rupture, thus effectively preventing the danger caused by overheating. The following editor will introduce you to the types of thermal fuses and their correct usage. 1. Organic type thermal fuses are mainly composed of movable contacts, fusible and springs. 2. Porcelain tube type thermal fuse is mainly made of insulating porcelain tube. Square-case thermal cutoffs, resin-wrapped fusible alloy wires, then connected to the fuse current. 1. The thermal fuse must be used reasonably within the specified parameters and must meet the specifications of the fuse type itself. 2. In the actual installation process, in order to avoid transferring the stress to the fuse, please be sure to pay attention to the displacement and vibration of other accessories. 3. After the fuse is installed, make sure that the ambient temperature will not exceed its maximum operating temperature after the fuse blows.

What is the principle of thermal fuse

Thermal fuse principle The thermal fuse is an electrical safety protection device, which is an automatic disconnect circuit protector. Its principle is: when the temperature in the circuit exceeds a certain value, the internal structure of the thermal fuse will change, making The current in the circuit is interrupted, thereby protecting the circuit from damage.
