Leakage protector is a more effective means to prevent electric shock, can meet the needs of safe electricity, to ensure the normal operation of equipment, but at present, many factories will choose not to install because of the increase in the cost of installing leakage protector and the deterioration of the stability of the power supply. Here is a small series with Senli motor to understand aboutThree-phase asynchronous motorThe leakage protection.

       The purpose of the leakage protector is to ensure the safety of electricity, and the line will trip if there is a problem, resulting in no power. This we need to analyze according to the situation of the site, if the three-phase asynchronous motor operating environment site, does not belong to the dangerous wet environment, we can indeed choose not to install the leakage protector, but to ensure that the motor shell must protect the zero.

       The power supply side of the leakage protector is connected with a three-phase four-wire power supply, and the outlet line of the leakage protector is connectedThree-phase asynchronous motorNote that the input and output of the leakage protector should not be reversed, if the input and output of the leakage protector are reversed, the trip coil of the electronic leakage protector can not be cut off with the power supply, so that the power is burned for a long time.

       But for now, the general staff will not directly contact the equipment housing, and short circuit protection, overload protection and other safety measures are relatively complete, but there is really a leakage of this situation, the larger current will also make the overload protection action.
