Description

Technical Field

[0001] The invention relates to the technical field of monitoring alarm devices, and in particular to a monitoring alarm device for motor current. Background Art

[0002] A motor refers to an electromagnetic device that realizes electrical energy conversion or transmission according to the law of electromagnetic induction, including electric motors and generators. When a motor is started for the first time, it will generate a large current. In actual operation, as the load increases, the current passing through the motor will be even larger. When the current is too large, it will cause an overload, affecting the normal operation of the motor. In order to ensure the stable operation of the motor, it is necessary to monitor the load and current of the motor when the motor is running, and generate an alarm signal when the current is too large, so that the operator can obtain the motor overcurrent signal and better ensure the normal operation of the motor. However, as far as the existing motor current monitoring and alarm devices are concerned, when in use, the monitoring and alarm devices are generally fixed. It is fixedly installed on the distribution cabinet. By patrolling the distribution cabinet, the instantaneous current and alarm information of the motor during operation can be obtained. If the monitoring alarm device is damaged, it needs to be disassembled and generally mailed back to the manufacturer for repair. However, the monitoring alarm device cannot be installed quickly during replacement to avoid affecting the monitoring function of the motor current. The operation is not convenient enough. When the existing monitoring alarm device is in use, the monitoring alarm device is connected to the background through a network line, so that the current and alarm information can be conveniently viewed through the background. However, when in use, the network line often generates a disconnection signal, which affects the monitoring effect of the background, and the network line and the monitoring alarm device cannot be connected to each other more stably.
