introduction：The cutting mode of the cutter is related to the fiber direction of the stalk。The direction of the fibers of the stalk is parallel to its axis，Therefore, the direction of cutting into the stalk is closely related to cutting resistance and power consumption。The so-called cutting method mainly refers to the direction of the cutter into the material，To sum up, there are two basic methods: tangent and slide cutting。

introduction：What makes an electric motor different from other electric loads is when it starts，The starting current is rated5-7times，The peak value of starting current is the peak value of rated current10-12times。Therefore, the protection of the circuit breaker used in the motor circuit should be able to avoid the starting current

introduction：When partial discharge occurs inside the switchgear，The electromagnetic waves generated by the discharge are mostly shielded by the metal housing of the switchgear，Small parts pass through the joints of the metal box，At the same time, a transient voltage to ground is generated。The degree of partial discharge inside the switch cabinet can be reflected by measuring the instantaneous potential change on the outer surface of the metal box with the test probe。

introduction：As long as the internal structure of the transformer is opened, you can see the complex and diverse circuit board and circuit design，intricate，Circuits and wires are criss-crossed，But the wiring of the transformer is not just to say that it can be connected，It is generally thought that the wiring of the transformer is to pay attention to the correctness and direction of the line，One wrong press will burn the voltmeter and the ammeter，In severe cases, it loses its effect。The coil of the transformer is also wound in a variety of ways，It usually starts from the positive terminal of the power supply，Go through the transformer to the negative terminal of the power supply，The direction of the voltage and current of the coil should also be noted，Is generally divided into4Rent for connection，The connection method can be different kinds of connection，The way is different, so to speak，But make sure its connected correctly。
