Motor Thermal Protector
Motor is a very wide range of mechanical and electrical equipment, work in all walks of life often used. If you do not take protective measures on the motor, it may cause a safety accident, motor-driven electrical hazards in use may present a risk of electric shock and a fire hazard.
What Is The Motor Thermal Protector
Motor thermal protector is a bimetallic superheat protector, is the thermal protection device for the normal operation of the motor. In Ya Xun, to provide a full range of motor thermal protection, such as: DC, single-phase, three-phase, low-voltage motor, high-voltage motor.
There are many reasons for motor overheating, such as running overload, selection is not appropriate, cooling failure, lack of monitoring and necessary maintenance leading to premature aging of insulation.
The motor in the run-time will produce losses, these losses on the one hand to reduce the efficiency of the motor, on the other hand the loss turns into a motor heating, so that the motor winding temperature increases.
The life of the winding insulation material is related to its operating temperature. The temperature is too high, the insulation material will accelerate aging, so that a significant reduction in insulation performance, significantly shorten the life of the motor, even the risk of fire and electric shock hazard. Therefore, the purpose of motor overheating protection, mainly in the design, manufacture, installation and use of motor protection measures, when the motor is operating under certain load and heat dissipation conditions, the temperature of the winding does not exceed the allowable value of the standard.

What Is A Fuse?
Fuses are also known as current fuses, and the IEC127 standard defines it as a "fuse body." It is primarily a function of current overload protection. When the circuit fails or abnormal, accompanied by rising current, and the rising current may damage some important devices in the circuit, it is possible to burn the circuit or even cause a fire.
If the circuit correctly install the fuse, then the fuse will rise in the current to a certain height and heat, when the fuse itself cut off the current, so as to protect the safe operation of the circuit.
Fuse Characteristics
Resistivity is large; low melting point.
Small size, easy to install
Disjunction capability precision, reliability
Different structural features, installation in various forms
Under normal conditions, the fuse has a long shelf life
Recoverable fuse, reset can be repeated use
Long life of the fuse, in case of fault-free circuit, synchronized with the life of the equipment
Thermal fuse manufacturing
The thermal fuse is a non-resettable, one-time overheat protection element, and the current fuse is a one-time overcurrent protection element. Series connection in a variety of electrical power input, when the use of household appliances in the abnormal temperature changes, or temperature out of control lead to excessive temperature rise, the thermal fuse can quickly cut off the circuit to avoid the occurrence of fire.
Commonly used in: hair dryer, iron, rice cookers, electric stoves, transformers, motors, drinking fountains, coffee pots and so on.

Structural Classification Of Thermal Fuse
organic type metal shell temperature fuse is a combination, the composition of the structure are:
1. Pin (A), 2. Sealed resin, 3. Insulating ceramic, 4. Fine spring, 5. Star reed, 6. Coarse spring, 7. wafer, 8. temperature sensing block, 9. The housing, 10 Pin (B).
When the temperature insurance is in normal operation, the current flows from the left lead to the sliding contact and flows through the metal housing to the right lead. When the external temperature reaches the predetermined temperature, organic matter can melt melt, the compression spring will become loose. That is, spring expansion, sliding contact (slidingcontact) and the left side of the separation. The circuit will cut off, the current between the sliding contact and the left lead is cut off. the temperature fuse will fail and can not be used again.
2, easy to melt alloy wire thermal fuse has ceramic shell and square shell, its temperature sensing element is a fusible gold.
Product structure: is the axis of the symmetrical lead, fusible alloy wire, and resin mixture and insulated porcelain tube, plastic shell.
When the temperature rise of the heating element is set to a temperature, the resin mixture begins to liquefy, when the melting point is reached, with the help of the resin mixture (increasing the surface tension of the melted alloy), has been molten alloy wire in the resin mixture under the action of tension, quickly to both ends of the wire as the center shrink into a spherical, and thus permanently cut off the circuit.
Technical Parameters And terminology Of Thermal Fuses
(1) Rated operating temperature (Tf):
The temperature fuse is tested according to the standard method to change the temperature of its conductive state. According to IEC6091 standards-based security provisions, the temperature fuse must be operated within the rated operating temperature + 0 / -10 C (the Japan Electrical Supplies Act provides a tolerance range of ± 7 C).
(2) Operating temperature Found:
The temperature fuse is heated in the silicone oil tank at a rate of 0.5-1 C per minute, detection current is less than the fusing temperature measured at 10mA condition. It is the actual operating temperature of the temperature fuse.
(3) Holding temperature (Th):
When the temperature fuse passes the rated current, can hold for 168 hours without changing the maximum temperature of its conductive state.
(4) limit temperature (Tm):
Temperature fuse can withstand the maximum temperature for 10 minutes reconnection phenomenon never occurs.
(5) Rated current (Ir):
The maximum current that the temperature fuse can carry.
(6) Rated voltage (Ur):
Temperature fuse maximum operating voltage.
