High current jump temperature controller is a temperature control device for controlling high current load.
First, the working principle
It usually uses a bimetal sheet as a temperature sensing element. When the temperature of the controlled object rises, the bimetallic sheet is deformed by heat. When the temperature reaches the set value, the degree of deformation of the bimetal sheet reaches a certain degree, and the trigger mechanism makes the contact quickly disconnected, cutting off the power supply of the large current load, so as to achieve temperature control. When the temperature drops, the bimetal sheet gradually restores to its original state, and the contact will automatically close at a certain temperature to restore the power supply to the load.
Ii. Characteristics
High current carrying capacity: can withstand large current, suitable for high power equipment temperature control, such as electric heating equipment, industrial oven and so on.
Fast action: When the temperature reaches the set value, the circuit can be quickly disconnected, the response time is short, and the temperature is too high to effectively prevent damage to the equipment.
Temperature accuracy: It has a certain temperature control accuracy and can be adjusted according to different application requirements.
High reliability: Due to the use of mechanical structure, relatively stable and reliable, not easily affected by external interference.
Easy installation: usually has a standard installation size and interface, easy to install in a variety of equipment.
3. Application fields
Industrial heating equipment: such as ovens, furnaces, heat treatment equipment, etc., used to control the temperature during the heating process to ensure the safe operation of the equipment.
Household appliances: such as electric water heaters, heaters, rice cookers, etc., to prevent excessive temperature from causing safety accidents.
Motor protection: During the operation of the motor, if the temperature is too high, the jump thermostat can cut off the power supply and protect the motor from damage.
New energy field: such as the temperature control of electric vehicle battery packs to prevent battery overheating affecting performance and safety.
