Embodiment Construction
[0036] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0037] Such as Figure 1 to Figure 6 As shown, a protection method for an asynchronous motor, the method includes the following steps:
[0038] Step 1: Disconnect the power supply of the asynchronous motor;
[0039] Step 2: Select a high-voltage circuit protector and connect it in series to the high-voltage circuit to check whether the high-voltage circuit protector is operating normally;
[0040] Step 3: Connect the asynchronous motor de-energized in step 1 to the high-voltage circuit protector after the switch in series;
[0041] Step 4: Fix the high voltage circuit protector in a ventilated and waterproof place;
[0042] Step 5: Power on the asynchronous motor with the high-voltage circuit protector placed in step 3;
[0043] Wherein, the h...
