Large-scale fan, high voltage motor operation monitoring system of large-scale fan and monitoring method of monitoring system

Abstract

The invention discloses a large-scale fan and a high voltage motor operation monitoring system of the large-scale fan. The high voltage motor operation monitoring system is used for monitoring a motor (6) and the fan (7). The motor (6) has access to a power supply (2) through a breaker (3). The monitoring system is provided with motor data collecting equipment (4) and is connected with a PLC (8) through a ModBus (9), and the PLC (8) is connected with a network user (12) through a server (10) and an interchanger (11). The invention further discloses a monitoring method of the monitoring system. By means of the technical scheme, real-time monitoring, detail data analysis, history parameter comparison and the like are achieved. The monitoring system is convenient to use, completely solves the problem that the motor and the fan are difficult to monitor and enables station operators and managers to conveniently know the operation situations of core equipment.

Description

technical field [0001] The invention belongs to the technical field of large-scale high-voltage motors and fan units, and relates to their operation control technology. More specifically, the invention relates to a large-scale fan and its high-voltage motor operation monitoring system. In addition, the present invention also relates to the monitoring method adopted by the above monitoring system. Background technique [0002] At present, in the domestic heavy industry enterprises, the protection equipment for large high-voltage motors and fan units is complete. However, there has never been a centralized monitoring system in the real-time operation of the equipment, which has resulted in some important core equipment not being properly monitored or inspected by humans, or in some emergencies, when there are abnormal signs, they cannot be controlled in time, which leads to Major failure and loss of equipment. [0003] Such as figure 1 As shown, in the operation monitoring ...

AI Technical Summary

Problems solved by technology

This monitoring method is not only passive, but also has poor real-time performance, slow response and is very dependent on the sense of responsibility of the post workers. When encountering special circumstances (incomplete inspection), the motor 6 (or fan 7) is in a state of "out of control". Management positions cannot keep abreast of the operation of core equipment, and cannot take corresponding preventive measures for abnormal signs of equipment.
