Motor protector of CD1 electric hoist
The CD1 electric hoist motor protector has the mechanical development of the past for electronic and intelligent, can directly display the parameters of motor current, voltage, temperature, sensitivity, high reliability, multiple functions, convenient debugging, protection fault type of stick out a mile, which reduces the motor is damaged, and greatly facilitate the fault judgment, is conducive to the production site of fault processing and shorten the recovery time of production.
Due to the continuous development of insulation technology, not only to increase the output of the motor design, and reduce the volume, heat capacity of the new CD1 electric hoist motor is more and more small, load capacity is more and more weak; due to the improvement of production automation, the motor always runs in frequent starting, braking, reverse and variable load and so on many kinds of ways, put forward higher request to the motor protection device.
CD1 electric hoist motor protection device of traditional dominated by thermal relay thermal relay, but low sensitivity, large error, poor stability, protection is not reliable. Indeed, although many of the equipment installed in the thermal relay, but motor damage and affect the normal production of the phenomenon is still exist.
The ideal CD1 electric hoist motor protector is not the most functional, not the so-called advanced, but should meet the actual needs, to achieve unity of economy and reliability, high ratio of performance to price. Reasonable selection of protection device type, function according to the actual situation, considering the protector installation, adjustment, simple and convenient to use, it is more important to choose the protector of high quality.
