6the reliability service of electrical equipment, improves the continuous reliability service ability of electric system, realizes presence and detects, monitors and failure prediction, become SF to its performance
6important research direction in electrical equipment application.SF
6the effect of gas in high-voltage electric switch unit is arc extinguishing and insulation, SF
6sF in electrical equipment
6if the micro-water content of gas exceeds standard will have a strong impact on SF
6the safe operation of electrical equipment.SF
6electrical equipment in use, its inner SF
6gas can cause gaseous tension to reduce due to the reason such as loss or leakage, works as SF
6when gaseous tension reduces to a certain extent, can due to insulate not or when device interior discharge, Arcing fault time arc extinguishing ability inadequate and major accident occurs, the SF therefore in use
6electrical equipment needs SF therein
6gaseous tension should carry out tonifying Qi time not enough in time.
In order to prevent that SF occurs
6the accident that electrical equipment Leakage Gas causes, except needs monitoring SF
6the SF of inside electric appliance
6gaseous tension, also needs monitoring to place SF
6sF in the environment of electrical equipment
6whether gas exceeds standard, and avoids bringing danger to operating personnel.
Existing SF

6the monitoring system of gas is separately independent setting, and two systems are in the duty of unlatching all always, do not integrate according to these two systems technology relevances.In this programme, according to the relevance of two systems, effectively integrate, monitoring resource can be optimized further.This programme according to actual conditions needs, for monitoring SF
6sF in electrical equipment
6the monitoring of equipment module of gas is in the duty of unlatching always, SF in the equipment that central processing unit detects according to the pressure transducer of monitoring of equipment module
6gaseous tension judges, if the pressure in equipment does not reduce, or when the pressure reduced is very little, and SF
6gas can not occur to leak, now, to this SF of placement
6sF in the environment of electrical equipment
6gas carries out the SF monitored
6gas monitoring system, without the need to opening, can be closed.Only can reduce by the pressure in checkout equipment in monitoring of equipment module, or when the pressure reduced exceedes setting value, SF
6gas just likely leaks, and now, needs to open SF
6gas monitoring system detects places this SF
6sF in the environment of electrical equipment
6gas content.According to actual needs, can not need to be closed when starting in indoor monitoring module, opened when needs use, optimize monitoring resource further like this.The improvement of this programme is mainly that carrying out integration to two system hardware modules improves, SF in the equipment that central processing unit detects according to the pressure transducer of monitoring of equipment module
6gaseous tension judges, by unlatching or the closedown of monitoring modular in gauge tap pulpit, this is that those skilled in the art are easy to namely by hardware implementing according to chip controls principle, or is realized by programmable chip, does not belong to the improvement for software.
Further, described monitoring of equipment module also comprises for SO in checkout equipment
