怀化Does the PTC electric heater need to be equipped with a safety device

The characteristics and main parameters of the PTC electric heater fuse are the rated current and rated current, which refers to the larger working voltage that the fuse can withstand after being disconnected. When the fuse is connected, the working voltage borne by both parties is much lower than its rated current. There are many types of fuse tubes. Common fuse tubes are mainly divided into three types: glass tube fuses with lower recognition ability, ceramic tube fuses (with high recognition ability), and polymer self-healing fuses (made of PPTC plastic polymer). There is no need for professional temperature controllers and humidity sensors such as thermal resistance platinum thermal resistance for temperature evaluation, You can perform temperature control operation on the electric heater,

Its temperature control adjustment relies on its own raw material characteristics, and the tooling manufacturer makes the product have much higher identification working voltage characteristics than other fuse tubes. Generally, it is stipulated that the rated current of the fuse tube when used exceeds the reasonable working voltage of the power circuit. During long-term operation, the rated voltage of the fuse is a large current flow rate. Assuming the maintenance current is the current Ir, the rated voltage of the fuse that should be used can reduce the voltage of the standard fuse. The higher the operating temperature, the higher the temperature of the fuse during operation, and the shorter its service life. The main point here is that the temperature of the gas around the safety tube should not be confused with the room temperature. PTC ceramic heaters save costs and have a long service life.
