Abstract
The invention discloses a GIS (Geographic Information System) equipment SF6 gas leakage monitoring automatic venting device, comprising an SF6 gas monitor and an alternating current contactor, an alarm signal output terminal of the SF6 gas monitor is connected with a monitoring background by virtue of an alarm output circuit, wherein a coil of the alternating current contactor is connected with the alarm signal output terminal of the SF6 gas monitor, thus the alternating current contactor and the alarm output circuit are connected in parallel, and a normally opened contact of the alternating current contactor is used for controlling starting and stopping of an exhaust fan. In the invention, the alternating current contactor is connected in the alarm output circuit of the gas monitor in series, the normally opened contact of the alternating current contactor is used for controlling starting and stopping of the exhaust fan, when gas leaks, the exhaust fan of a GIS equipment room can be automatically opened, and personal safety of personnel working in the GIS equipment room can be guaranteed.
Description
Technical field
The invention belongs to GIS equipment SF6 gas leakage detection equipment technical field, particularly a kind of GIS equipment SF6 gas leaks keeps watch on automatic exhaust device.
Background technology
At present, in electric system, GIS equipment is used widely because maintenance workload is little, floor area reaches advantages such as reliable less more and more.Be flooded with a large amount of SF6 gas in the GIS equipment as insulating medium, install in the general GIS canyon by the SF6 gas monitoring instrument, the warning output loop of SF6 gas monitoring instrument connects the monitoring backstage; But if when having the people in the GIS canyon, to work; Longer when monitoring backstage time that signal notifies the staff then to waste again that receives the report for police service, and SF6 gas is in case leak, with producing poisonous low fluorine compounds; Human body can cause poisoning after sucking, threat to life when serious.
Summary of the invention
The present invention provides a kind of GIS equipment SF6 gas to leak and keeps watch on automatic exhaust device, uses this equipment can in time get rid of the harmful gas SF6 of GIS equipment, and the assurance staff's is healthy.
A kind of GIS equipment SF6 gas leaks keeps watch on automatic exhaust device; Comprise SF6 gas monitoring instrument, A.C. contactor; The alarm signal output ends of SF6 gas monitoring instrument connects the monitoring backstage through the warning output loop; Wherein the coil of A.C. contactor connects the alarm signal output ends of SF6 gas monitoring instrument, makes A.C. contactor parallelly connected with the warning output loop, and the normally opened contact of A.C. contactor is used for controlling the start and stop of air exhauster.
Said GIS equipment SF6 gas leaks the supervision automatic exhaust device and is arranged on indoor lower.
The present invention is through being connected in series A.C. contactor in the warning output loop of gas monitoring instrument; Control the start and stop of extraction fan with the normally opened contact of A.C. contactor; When gas takes place to leak; Can open the extraction fan of GIS canyon automatically, the personal safety of assurance personnel when GIS equipment office work.SF6 gas monitor is installed on lower in the GIS canyon, and is quite sensitive for the SF6 gas-monitoring that leaks, and when the SF6 gas in the room air exceeded standard value, this monitor will send alerting signal to the monitoring background computer; A.C. contactor also receives signal and gets electric adhesive simultaneously, and its normally opened contact closure is opened the extraction fan of GIS canyon automatically, to outdoor exhaust, and also can be when reaching warning from the purpose of the outdoor exhaust of trend; When SF6 gas is lower than standard value, when alerting signal stops to export, the coil losing electricity of A.C. contactor then, its normally opened contact breaks off the extraction fan of closing the GIS canyon automatically.
As shown in Figure 1; A kind of GIS equipment of the present invention SF6 gas leaks keeps watch on automatic exhaust device; Comprise SF6 gas monitoring instrument, A.C. contactor, the alarm signal output ends of SF6 gas monitoring instrument connects the monitoring backstage through the warning output loop, and wherein the coil of A.C. contactor connects the alarm signal output ends of SF6 gas monitoring instrument; Make A.C. contactor parallelly connected with the warning output loop, the normally opened contact of A.C. contactor is used for controlling the start and stop of air exhauster.SF6 gas monitor is installed on lower in the GIS canyon, and is quite sensitive for the SF6 gas-monitoring that leaks, and when the SF6 gas in the room air exceeded standard value, this monitor will send alerting signal to the monitoring background computer; A.C. contactor also receives signal and gets electric adhesive simultaneously, and its normally opened contact closure is opened the extraction fan of GIS canyon automatically, to outdoor exhaust, and also can be when reaching warning from the purpose of the outdoor exhaust of trend; When SF6 gas is lower than standard value, when alerting signal stops to export, the coil losing electricity of A.C. contactor then, its normally opened contact breaks off the extraction fan of closing the GIS canyon automatically.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is the theory diagram that the present invention keeps watch on automatic exhaust device.
Embodiment
As shown in Figure 1: as shown in Figure 1; A kind of GIS equipment of the present invention SF6 gas leaks keeps watch on automatic exhaust device; Comprise SF6 gas monitoring instrument, A.C. contactor, the alarm signal output ends of SF6 gas monitoring instrument connects the monitoring backstage through the warning output loop, and wherein the coil of A.C. contactor connects the alarm signal output ends of SF6 gas monitoring instrument; Make A.C. contactor parallelly connected with the warning output loop, the normally opened contact of A.C. contactor is used for controlling the start and stop of air exhauster.SF6 gas monitor is installed on lower in the GIS canyon, and is quite sensitive for the SF6 gas-monitoring that leaks, and when the SF6 gas in the room air exceeded standard value, this monitor will send alerting signal to the monitoring background computer; A.C. contactor also receives signal and gets electric adhesive simultaneously, and its normally opened contact closure is opened the extraction fan of GIS canyon automatically, to outdoor exhaust, and also can be when reaching warning from the purpose of the outdoor exhaust of trend; When SF6 gas is lower than standard value, when alerting signal stops to export, the coil losing electricity of A.C. contactor then, its normally opened contact breaks off the extraction fan of closing the GIS canyon automatically.
