Example Embodiment

[0011] Such as figure 1 The 10KV step-down starter cabinet shown is characterized in that it includes a control part and an action part. The control part is used to drive the action part. The control part includes a magnetic reactor and a thyristor component, and the magnetic reactor is connected to the thyristor Components, SCR components are used to drive the action part.

[0012] The said action part includes a high-voltage starting cabinet and an asynchronous motor, the thyristor component controls the high-voltage starting cabinet, and the high-voltage starting cabinet controls the asynchronous motor.

[0013] The asynchronous motor is a high-voltage squirrel-cage asynchronous motor.

[0014] The magnetic reactor plus the SCR components form a closed structure outside the cabinet to adjust the magnetic field gap to control the starting current. During the starting process, only the control circuit breaker is closed. After a delay, the bypass circuit breaker is turned on to achieve a smooth start; , The order is reversed. The drive start mode of the high-voltage reactor is solved, and the personal safety of the operator and the safe operation of the equipment are guaranteed to a certain extent.

[0015] The above-mentioned implementation cases are only examples for clarifying the present invention, and are not intended to limit the implementation of the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
