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 achi...

Abstract

The invention relates to a 10KV step-down starting cabinet, characterized in that the 10KV step-down starter cabinet comprises a control part and an action part; the control part is used for driving the action part; the control part comprises a magnetoreactor and a silicon controlled rectifier assembly; the magnetoreactor is connected with the silicon controlled rectifier assembly; and the siliconcontrolled rectifier assembly is used for driving the action part. The invention has the advantages of stable operation, reduced starting current and small impact force on the equipment, convenient maintenance, low noise, and safer operation, providing a powerful guarantee for the safe operation of electric power.

Description

Technical field: [0001] The invention relates to a 10KV step-down starting cabinet, which belongs to the field of mining equipment. Background technique: [0002] The reactor in the step-down starter cabinet for mine motors is generally an open structure, with a large starting current, a large impact on the equipment, and it is easy to be affected by moisture and dust. Often, short-circuit tripping occurs during the start-up process, which breaks through the electric panel door, endangers the safe operation of operators, high-voltage equipment, and lines, and hinders production. Invention content: [0003] The present invention provides a 10KV step-down starting cabinet that can overcome the above-mentioned defects, and is used to control mine motors. [0004] The 10KV step-down starting cabinet provided by the present invention 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 inclu...
