Description
Technical field
The utility model relates to a kind of industry monitoring device, especially relates to a kind of online SF
6the quantitative warning system of Leakage Gas.
Background technology
SF
6synthetic in 1900 by two french chemist Moissan and Lebeau.From the sixties, SF
6be widely used in the primary cut-out and converting equipment in bulk of worldwide electricity industry as extremely superior insulation, arc-extinguishing medium.In today, SF
6gas almost becomes insulation unique in high pressure, extra high voltage circuit breaker and GIS and arc-extinguishing medium.
Pure SF
6gas is colourless, tasteless, do not fire, and chemical property is stable especially at normal temperatures, is more than 5 times of air specific weight.But in electric system, due to SF
6gas mainly serves as insulation and arc-extinguishing medium, under the factor impacts such as electric arc and shelf depreciation, high temperature, and SF
6gas can decompose.Its analyte generates corrosivity electrolyte after meeting moisture content, and especially some high toxicity analyte as SF4, S2F2, SOF2, HF, SO2 etc., causes dizziness and pulmonary edema as a large amount of suction people know from experience, even stupor and dead.
At present, indoor what relatively seal, due to sluggish in air circulation, SF
6and analyte indoor because many reasons may deposit, add SF
6gas is colourless, tasteless, thereby tour, maintainer are produced to great harm.When SF is housed
6the electrical room of equipment as GIS produce leak after, SF
6gas accumulates in the low sheaf space in terrace top, when reaching after finite concentration, indoor if staff enters, and can cause large cerebral anoxia, people is suffocated and cause a serious accident hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of online SF
6the quantitative warning system of Leakage Gas, solves SF is housed
6after the electrical room of equipment produces and leaks, be difficult for finding in time and people is suffocated, and then the problem of the hidden danger that causes a serious accident.
To achieve these goals, the utility model provides a kind of online SF
6the quantitative warning system of Leakage Gas, SF in testing environment air
6gas content and oxygen content, comprise SF
6and O
2two gas collecting devices, system host, controller of fan, blower fan and centralized control center, SF
6and O
2two gas collecting devices are by RS485 fieldbus and system host communication, and system host is leaded up to controller of fan control blower fan, separately lead up to RS485 communication and centralized control center's communication.
Also comprise humiture collection device, humiture collection device is also by RS485 fieldbus and system host communication.
1 SF of every 30-50 square metre spatial placement
6and O
2two gas collecting devices.
Centralized control center is upper PC.
The beneficial effects of the utility model are can be accurately, SF in the real time measure environment
6humiture in gas, oxygen and environment, real-time diagnosis warning and the automatic exhausting function of removing a hidden danger.
Brief description of the drawings
Fig. 1 is system architecture schematic diagram of the present utility model.
Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing:
As shown in Figure 1, the present embodiment provides a kind of online SF to embodiment
6the quantitative warning system of Leakage Gas, SF in testing environment air
6gas content and oxygen content, comprise SF
6and O
2two gas collecting devices, humiture collection device, system host, controller of fan, blower fan and centralized control center, centralized control center is upper PC, SF
6and O
2two gas collecting devices are by RS485 fieldbus and system host communication, system host is leaded up to controller of fan control blower fan, separately lead up to RS485 communication and centralized control center's communication, humiture collection device is also by RS485 fieldbus and system host communication.
1 SF of every 30 square metres of spatial placements
6and O
2two gas collecting devices.
The present embodiment is the situation of emphasizing safety in production according to current power system, is the intelligent on-line detecting system that provides health of human body safeguard protection to design, develop the staff of electrical room that SF6 equipment is installed; SF in the main testing environment air of system
6gas content and oxygen content, as SF in environment
6gas content exceeds standard or anoxic, can report to the police in real time, automatically opens ventilation blower simultaneously and ventilates, and have many functions of enriching such as humiture detection, duty voice message, teletransmission warning, the inquiry of historical data.
The present embodiment adopts the ultrasound wave method principle that tests the speed, can be in real time, quantitative measurment SF
6concentration, even at SF
6concentration also can detect effectively at 50ppm.Not only can reach the object guaranteeing personal safety, and can also guarantee that equipment normally moves; The ultrasonic sensor of imported with original packaging high stable and lambda sensor, can provide more one deck reliably protectings for field personnel.
