Abstract
The invention proposes a fast electric fire monitoring system which relates to the computer control system and is based on self diagnosis, aiming to solve the problem of long-term safety of the equipment and the system. In the invention, the self diagnosis system is applied to the electric fire monitoring system, so that a performance passivation test and data correction can be carried out on detecting elements in the system; meanwhile, insulation deterioration process of an electric distribution system can be detected, safety assessment on insulation degree can be carried out on various electric equipment in the newly installed electric distribution system. In the technical proposal of the invention, the detecting element is provided with a self-checking diagnosis circuit. All detecting elements in the technical proposal are detected simultaneously with a comparison database.
Description
Technical field
The invention belongs to the low-voltage electrical apparatus field, relate to electric fire monitoring system, particularly relate to electric fire monitoring system based on self diagnosis.
Background technology
According to statistics, opening circuit in electrical fire on firely accounts for 60%, and in the tripping operation of opening circuit of isolating switch, the tripping operation that earth fault causes accounts for 90%.Cause is the fire that the overwhelming majority causes for earth fault electric arc.RCD (RCD) can detect fault current over the ground; but the single RCD that is provided with by dispersion in large and medium-sized buildings is inefficient; need a cover Electric Leakage Fire Alarm to monitor the fault and the abnormality of electric wiring; find the hidden danger of electrical fire timely, in time report to the police.State Bureau of Technical Supervision, the 9.5th requirement of the GB50045-95 of Ministry of Construction's " Code for fire protection design of high rise buildings " (2005 editions) are provided with Electric Leakage Fire Alarm under construction.
But distribution system electric leakage is a gradual change, long-term process, and existing Electric Leakage Fire Alarm is all constructed on RCD (RCD) threshold detection technique.The magnetic material of conventional residual current detection technique is a permalloy simultaneously, and the long-term work performance can be degenerated, and signal has passivation effect, so system can not fundamentally ensure long-term safety.
Summary of the invention
Technical matters of the present invention is: propose a kind of electric fire monitoring system based on self diagnosis when relating to computer based control system fast, the difficult problem of the medium-term and long-term safety of solution equipment and system.
Technical scheme of the present invention is: the appliance fire supervisory system of our company's development is employing system self diagnostic system, can carry out performance passivation test to intrasystem detecting element, and carry out the adjustment of data, can the insulation ag(e)ing process of distribution system be detected simultaneously, and various consumers in the new installation distribution system are made the safety evaluation of insulation degree.
The detecting element detecting element has a self-checking diagnosis circuit in the technical scheme of the present invention.
All detecting elements detect simultaneously in the technical scheme of the present invention, and comparison database is arranged
The invention has the advantages that the technical scheme of the self diagnosis that has adopted a kind of practicality, solved the difficult problem of the medium-term and long-term safeguard protection of equipment and system, thereby reached purpose of the present invention.
Major technique feature technology parameter or index:
Intrasystem detecting element performance passivation test: susceptibility 0.2%
Adjustment of data rate: 0.2%
The insulation ag(e)ing process of distribution system detects: the aging equivalent rate of change 0.2%/moon
The safety evaluation of consumer insulation degree: the expection insulation ag(e)ing phase (precision resolution: month)
Embodiment
Further specify technical scheme of the present invention and advantage below in conjunction with embodiment.
Embodiment:: the appliance fire supervisory system of our company's development is employing system self diagnostic system, can carry out performance passivation test to intrasystem detecting element, and carry out the adjustment of data, can the insulation ag(e)ing process of distribution system be detected simultaneously, and various consumers in the new installation distribution system are made the safety evaluation of insulation degree.
The detecting element detecting element has a self-checking diagnosis circuit in the technical scheme of the present invention.
All detecting elements detect simultaneously in the technical scheme of the present invention, and comparison database is arranged
The foregoing description provides to being familiar with the person in the art and realizes or use of the present invention; those skilled in the art can be under the situation that does not break away from invention thought of the present invention; the foregoing description is made various modifications or variation; thereby protection scope of the present invention do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
