Bimetallic thermal protection switch for motors
st01, 17am, TB02, KSD9700 bimetal thermal protection switch is used for: electric motor, single phase motor, three phase motor overload, dc motor, motor winding thermal overload protector.
A thermostat using a bimetallic sheet as a temperature sensing element.
The motor thermal protector product is a thermostat that uses a bimetallic sheet as the temperature sensing element. When the electrical appliance is working normally, the bimetallic sheet is in a free state and the contacts are in a closed/open state. When the temperature rises to the action temperature value When the bimetallic element is heated, it generates internal stress and acts quickly, opening/closing the contacts, cutting off/connecting the circuit, thereby playing a thermal protection role.
The utility model provides a motor thermal protector testing device, which includes a temperature control device, a power supply circuit and several test circuits connected in parallel with the power supply circuit. The temperature control device is used to simulate the working environment temperature of the motor thermal protector and the power circuit. The test circuit forms a series path with the motor thermal protector to be tested by connecting the circuit. The utility model simulates the working environment temperature of the motor thermal protector through a temperature control device. Use a simple test circuit to replace household appliances. After powering on, the motor thermal protector is heated, kept warm, and cooled down. The on-off status of the motor thermal protector can be judged based on the light bulb in the test circuit being on or off, which can meet the requirements of testing multiple products at the same time, which is simple and efficient.
The motor thermal protector series product is a thermostat that uses a bimetallic sheet as a temperature sensing element. When the motor is working normally, the bimetallic piece is in a free state and the contacts are in a closed/open state. When the temperature rises to the operating temperature value, the bimetallic element is heated and generates internal stress to act quickly, opening/closing the contacts, cutting off/connecting the circuit, thereby playing a thermal protection role. When the temperature drops to the reset temperature, the contacts automatically close/open and return to normal working conditions. Widely used in household appliance motors and electrical equipment, such as washing machine motors, air conditioning fan motors, transformers, ballasts, electric heating appliances, etc.
Precautions
1. When using contact temperature-sensing installation, the product should be close to the installation surface of the controlled appliance.
2. Do not collapse or deform the plastic or metal casing during installation to avoid affecting performance.
3. For metal-cased products with an insulating jacket, do not remove the insulating jacket or crush it during installation to avoid leakage and ensure safe use.
4. When the product is used in a circuit with a current of no more than 5A, a conductor with a copper core cross-section of 0.4-0.75㎜2 should be selected to connect it.
5. The product should be stored in a ventilated, clean, dry, and non-corrosive gas-free place with a relative humidity of less than 90% and an ambient temperature of less than 40°C.
