Motor Thermal Protector Supplier

Motor Thermal Protector<br />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.<br /> <br />What Is The Motor Thermal Protector<br />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-se, three-se, low -voltage motor, high-voltage motor.<br />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.<br />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.<br />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.<br /> <br />Example - Three-se Motor Overheat Orotection (6AP, 3MP, 5AP, 2MP, 17AM, 8AM)<br />Three - se motor thermal protection. Its advantage is that, it has a dual function of current overload protection and thermal protection.<br />When the motor winding coil current overload (large) exceeds the motor current rating multiple, thermal protection device can automatically disconnect the power circuit, thus protecting the motor safety.<br />17 AM, 6AP has a motor overload, lack of se, stall and other circuits play a protective role. The method can be applied to any connection form three-se motor, submersible pumps, etc., automatically disconnect the power circuitry within 4 to 10 seconds.<br />The thermal protector can be installed in the motor, can also be installed outside the motor, can also be installed on all machine control panels. Even can be installed on the wall of the power distribution board. It can replace the thermal relay and AC r used in conjunction with the motor protection device.<br />Yaxing thermal protector can be used in high pollution environment (This is because the AC r is not fully enclosed and its silver are particularly susceptible to damage in highly polluted environments, so AC rs can not be used in highly polluted environments). With energy saving, action sensitive, reliable, affordable and so on. Easy to use and install, there are obvious economic and social benefits. Now the world, there is no thermal protection device can be installed in the device control board, and can be wall- mounted distribution board. This is Ya Xun's patented product thermal protector advantage.<br />This thermal protection wide range of applications.
