The embodiment of the invention provides a state detection method and device for a dragging system. The method comprises the steps; acquiring operation information of a dragging system after a detection signal is injected; obtaining the state characteristic value of the dragging system according to the operation information; and determining the current state of the dragging system according to the state characteristic value and a preset reference value. According to the state detection method and device for the dragging system provided by the embodiment of the invention, the operation information of the dragging system in the operation working process after the detection signal is injected is obtained, and the operation information is analyzed and processed to obtain the state characteristic value, so that the current state of the dragging system is determined according to the state characteristic value and the preset reference value, rapid definition of the working state of the dragging system is achieved, and the safety generation detection requirement is better met.
Description
technical field [0001] The invention relates to the technical field of electrical field, in particular to a method and device for detecting the state of a drag system. Background technique [0002] In industrial electrical equipment, the drive system mainly refers to the motor and frequency converter, and the combined application of motor and frequency converter has been widely used as an effective method of industrial energy saving. With the promotion of high-voltage motors, frequency converters have also been widely used in metallurgy, petroleum and petrochemical industries. As the most commonly used driving method for fan and pump motors, the safety, testing, and fault warning of frequency converters have been extensively studied, especially in special processes such as petrochemical industry, the monitoring of frequency converters is more important . At present, effective active monitoring and detection methods are lacking in the drive system for motors and frequency c...
