Do You Know The Application Scenarios Of Thermal Relay?

As a temperature-sensitive electrical control element, the core function of thermal relay is to control and protect the circuit through temperature changes. It is widely used in many fields and plays a vital role. In the power system, thermal relay is a key component to protect circuits and electrical equipment from damage caused by overload, short circuit and other faults. It can quickly cut off the current when the equipment fails according to the set rated current and voltage values ??to ensure the safety of the equipment.

In addition, thermal relays also play an important role in the field of industrial automation control. It can set the working range according to the working environment and load conditions, maintain circuit stability, solve problems such as frequent equipment switching and voltage fluctuations, thereby effectively extending the service life of the equipment. At the same time, thermal relays are also used in the protection of household appliances, such as induction cookers, ovens, etc., as well as cooling systems, electrified railways, wind power generation and other fields, providing comprehensive circuit control and protection for various electrical equipment. Thermal relays play an indispensable protective role in many fields with their unique temperature control characteristics and wide applicability.

In the field of electrical heating, thermal relays are mainly used to control the temperature of the heater to prevent accidents caused by overheating. For example, in an electric kettle, a thermal relay can control the temperature of the heater to ensure that the water temperature is not too high, thereby avoiding dangerous situations such as water drying up or explosion. Similarly, thermal relays can also be used in appliances such as ovens and induction cookers to ensure the normal operation and safe use of appliances.

In the field of air conditioning and refrigeration, thermal relays are mainly used to control the start and stop and protection of the compressor. After the air conditioner has been used for a period of time, the compressor will overheat. If it is not shut down in time, it will cause damage to the compressor. At this time, the thermal relay can play a role. When the temperature exceeds the set value, the thermal relay will automatically cut off the power supply to protect the compressor from damage.

In the field of motors, thermal relays are mainly used to protect the motor from damage due to overload and short circuit. When the motor load is too large or a short circuit occurs, the motor will heat up. If it is not shut down in time, it will cause damage to the motor. At this time, the thermal relay can play a role. When the motor temperature exceeds the set value, the thermal relay will automatically cut off the power supply to protect the motor from damage due to overload and short circuit.
