How to protect explosion-proof electric hoist power components

The motor is one of the important power components in explosion-proof electric holes. The use of the motor determines the life of explosion-proof electric hoist. Therefore, there is usually a protective device for the motor portion. Due to the continuous development of insulation technology, it is necessary to increase the design of the motor. The output needs to be reduced, so the thermal capacity of the new explosion-proof electric gourd motor is getting smaller and weaker, and the load capacity is getting weaker, and due to the improvement of production automation, it is often necessary to frequent motor operation in start, braking, commutation and variable load. In various methods, a higher requirement for motor protection devices.

The traditional explosion-proof electric hoist motor protection device is mainly a "hot relay", but the thermal relay is low, the error is large, the stability is poor, and the protection is unreliable. The phenomenon that the motor is damaged and affecting normal production is still very common. The ideal motor protector is not more functional, nor a better motor, but should meet the actual needs of the scene and achieve unified economic and reliability. Value for money.

According to the actual situation of the site, the type of explosion-proof electric hoist motor protector is selected and considers the installation, adjustment, and convenience of use of the protector. At the same time, if you want explosion-proof electric hoists better, safer, more reliable, must always have more explosion-proof electric hoists to maintain maintenance and maintenance to ensure longer motor life and more flexible use!
