Abstract

The invention relates to a main transformer air cooling control system potential fault active processing method. According to the method, corresponding cooling unit modules are designed and set according to the number, operation parameters and conventional operation loads of motor groups in a main transformer air cooling system; in conventional operation, the operation parameters of corresponding motors such as voltage, current, phase sequence and the like are monitored in real time through independent monitoring channels; a daily operation baseline indicator is set for each motor, and a signal processing unit divides operation data into a "normal" data group, an "attention" data group, an "abnormal" data group and a "fault" data group, and "attention" and "abnormal" alarm is defined according to the indicator; and when the operating indicator of a monitored motor exceeds a corresponding alarm indicator, namely, when alarm information is triggered, the information is comprehensively judged through a programmable logic device, and is outputted to a man-machine interface, a remote transmission channel or a corresponding execution device so as to be processed.

Description

A kind of active air-cooled control system incipient fault initiatively method of disposal
Technical field
The present invention relates to air cooler control system, especially relate to a kind of active air-cooled control system incipient fault initiatively method of disposal.
Background technology
Known active air-cooled cooling unit does not have early warning mechanism, at blower fan group run duration, is only divided into " normally ", " fault " two states, and when cooling unit and occurring catastrophic failure, whole blower fan group enters immediately cuts state entirely, very affects production.If at blower fan group run duration; can provide can the method for early warning mechanism, to go wrong hidden danger in blower fan group, but does not also affect blower fan group when running well; enable staff's Timeliness coverage, before catastrophic failure (motor protecter action) occurs, processing motor runs hidden danger in time.Avoid occurring real catastrophic failure when high load capacity arrives, impact is produced.This type of early warning mechanism is also there is not in currently available technology.
Summary of the invention
In order to overcome the deficiency in background technology, the invention discloses a kind of active air-cooled control system incipient fault pre-judging method.
In order to realize described goal of the invention, the present invention adopts following technical scheme: a kind of active air-cooled control system incipient fault is method of disposal initiatively, and the method comprises following operation steps:
A) on the monitoring unit of original active air-cooled control system, add real time data monitoring modular, according to air cooling system motor number, carry out the Real-Time Monitoring of man-to-man three-phase alternating voltage, electric current, fluctuation amplitude parameter;
B) in software systems, real-time reception real time data monitoring modular sends real time data, and by data record in memory;
C) according to the recent service data of the concrete motor of air cooling system, determine the normal operation baseline index of active air-cooled control system motor, two-stage Alert Standard is set, by signal processing unit, service data is divided into " normally ", " attention ", "abnormal", " fault " four groups;
D) real time data received and daily Data Comparison are judged the operation conditions of active air-cooled control system, when the state of monitored motor emerged in operation reservation " attention " baseline criteria, will corresponding early warning mechanism be triggered; When real time data "abnormal" state, there is "abnormal" warning message in specific works unit motor, and when there being unit for subsequent use, initiatively quit work unit;
E) after the unit action that initiatively quits work described in step d) during "abnormal" state completes, initiatively start the unit for subsequent use identical with inactive unit quantity and put into operation.
Real time data monitoring modular in step a) of the present invention, adopts intelligent sensor each motor to ventilated machine system to carry out real-time measurement and the record of electricity.
Alert Standard in step c) of the present invention is realized by programming device and software kit.
Owing to have employed technique scheme, the present invention has following beneficial effect: according to group of motors quantity in main transfer wind cooling system and operational factor and conventional operation load, designs and arrange to cool set modules accordingly; During conventional operation, by the corresponding motor operating parameter (voltage, electric current, phase sequence etc.) of independently monitoring channel Real-Time Monitoring; For each motor arranges day-to-day operation baseline index, by signal processing unit, service data is divided into " normally ", " attention ", "abnormal", " fault " four groups, reports to the police according to this index definition " attention ", "abnormal"; When monitored motor operating index exceedes corresponding alarming index and trigger alert information, this information will carry out comprehensive descision by programmable logic device and output to man-machine interface, the actuating equipment of teletransmission passage or correspondence processes.
Adopt active air-cooled control system in this way; the real time execution parameter of each motor will be provided; and day-to-day operation baseline index; there is provided system cloud gray model quality evaluation in time and the incipient fault of prediction existence, make staff's timely precognition motor running quality trend before catastrophic failure (motor protecter action) occurs.Thus reduce classification maintenance rank.Described Alert Standard is realized by programmable device and software kit; can Multi-level Evaluation motor running quality; supplement the non-logical namely disconnected simple evaluate logic of motor protecter that traditional air cooling system adopts; before true fault appears in ventilated machine, timely anticipation is reported to the police; and provide specific aim to overhaul reference, at utmost reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of active air-cooled control system incipient fault of the present invention active method of disposal.
Fig. 2 is the schematic flow sheet of active air-cooled control system incipient fault of the present invention active method of disposal.
Embodiment
By explanation the present invention that the following examples can be detailed, disclose object of the present invention and be intended to protect all technological improvements in the scope of the invention.
Embodiment
A) on the monitoring unit of original active air-cooled control system, add real time data monitoring modular, according to air cooling system motor number, carry out the Real-Time Monitoring of man-to-man three-phase alternating voltage, electric current, fluctuation amplitude parameter.
B) in software systems, real-time reception real time data monitoring modular sends real time data, and by data record in memory.
C) according to the recent service data of the concrete motor of air cooling system, determine the normal operation baseline index of active air-cooled control system motor, two-stage Alert Standard is set, by signal processing unit, service data is divided into " normally ", " attention ", "abnormal", " fault " four groups; Described Alert Standard is mechanical erection position according to concrete motor reality, degree of aging and install the concrete operating mode comprehensive assessments such as ground environmental quality (as every daily mean temperature actual curve) and obtain, and flexible configuration, can be compatible strong, strong adaptability.
D) real time data received and daily Data Comparison are judged the operation conditions of active air-cooled control system, when the state of monitored motor emerged in operation reservation " attention " baseline criteria, by triggering corresponding early warning mechanism, motor associated components is carried out " maintenance of D level "; When real time data "abnormal" state, there is "abnormal" warning message in specific works unit motor, and when there being unit for subsequent use, initiatively quit work unit, carries out " maintenance of C level " work unit.
