Gear reducer daily maintenance protection measures
Under normal circumstances, in order to prevent the gear reducer from malfunctioning during operation and use, we take the measures of short-circuit protection, overload protection and phase loss protection to carry out routine maintenance and protection measures for the gear reducer.
First, short circuit protection
Short-circuit protection means that the low-voltage gear reducer below 7:500v is protected by the electromagnetic instantaneous release of the fuse or circuit breaker, so that the short-circuit fault of the gear reducer can be cut off in a timely and reliable manner. The power supply of the gear reducer avoids the loss of the gear reducer and its wiring and other electrical equipment due to the strong short-circuit current, which in turn causes significant losses.
Second, overload protection
We know that the overload current of the gear reducer does not necessarily melt. Therefore, we need to use the thermal release of the thermal relay or circuit breaker for overload protection, which can protect the overload current of the gear reducer. effect.
Third, lack of phase protection
In order to prevent the gear reducer from running out of phase, different phase loss protection methods are selected depending on the situation. Commonly, there are thermal relay protection, undercurrent relay protection, zero sequence voltage relay protection, and voltage loss and under voltage. (low voltage) protection.
The above three methods are the daily maintenance and protection measures of the gear reducer, and are also the necessary maintenance and protection measures for the gear reducer. If not considered, it may have a certain degree of influence on the service life and safety of the gear reducer.
