Wire rope hoist motor protection

  For now our case  Wire rope hoist  motor protector has been developed over the last mechanical electronic and intelligent, can directly display the motor current, voltage, temperature and other parameters, sensitivity, high reliability, multi-function, debugging is also convenient, species protection action after failure glance, reducing damage to the motor, but also greatly facilitates the fault judgment in favor of the production site production troubleshooting and shorten recovery time.
       As insulation technology continues to evolve, the design of the motor requires both increased output, but also reduce the volume required to make new  Wire rope hoist  motor is getting smaller and smaller thermal capacity, load capacity increasingly weak; longer because of production increased automation, often requires the motor to run in the frequent starting, braking, reversing and variable load a variety of ways, for motor protection devices put forward higher requirements.
       Traditional Wire rope hoist motor protection device for the thermal relay-based, but the thermal relay low sensitivity, error, poor stability, protection is not reliable.

Facts, too, though many devices installed thermal relay, but the motor damage and affect normal production of the phenomenon is still widespread.
       Ideal  rope hoist  motor protection function is not up, nor is the so-called advanced, but should meet the actual needs of the scene, so that the unity of economy and reliability with high performance and low cost. The actual situation at the scene reasonable choice protector types, functions, taking into account the protection installation, adjustment, easy to use, is more important to choose quality protector.
