Abstract
The utility model provides a sulfur hexafluoride online monitoring and alarming system. The sulfur hexafluoride online monitoring and alarming system comprises a system host and a sampling module, and is characterized in that the host is an integrated host, the host is additionally connected with a fan controller, a fan, an audible and visual alarm and an infrared sensor; the fan is connected with the host by the fan controller; the sampling module consists of a gas sensor and a temperature/humidity sensor. With the adoption of the structure, the temperature, the humidity, the oxygen density and the sulfur hexafluoride gas density data of an environment can be detected in real time; the system automatically starts the functions of voice prompt, fan ventilation, audible and visual alarm, fault event storage and the like when the indoor oxygen is less than a set value, and starts the fan to ventilate when the sulfur hexafluoride gas concentration exceeds the set value. The system provided by the utility model is simple and applied, the function configuration is optimized, the production cost is reduced, and the practicability, the convenience and the safety are improved.
Description
Technical field
The utility model relates to a kind of SF that is used in electric system GIS chamber
6The sulfur hexafluoride gas leakage monitoring warning system of the equipment such as isolating switch, AIS1, particularly a kind of Novel humanized are carried out the system that intelligent online detects the monitoring sulfur hexafluoride gas.
Background technology
The indoor SF of electric system GIS
6Sulfur hexafluoride in the breaker (is called for short SF
6) Leakage Gas, monitor improper or detect inaccurately, be easy to occur staff's safety problem or health problem.
The monitoring system of using at present mainly is the sonde-type system.System's composition can be divided into main frame and probe two parts consist of system.Host function: if realize each sampled point real-time communication, the data of each sampled point are sent to central processing unit process; Probe function: data sampling module mainly is to be responsible for the indoor SF of GIS
6Density and temperature acquisition carry out the A/D conversion, by the RS-485 communication, send data to main frame.The data that detect only have two data, and an oxygen (is called for short O
2) density and sulfur hexafluoride (be called for short SF
6) density of gas, the function singleness of realization lacks integrated effective efficiency.Can not effectively use, security is not high.
Summary of the invention
For improving sulfur hexafluoride on-line monitoring system function, improve Security of the system and effective usability, the utility model provides a kind of sulfur hexafluoride online monitoring alarm system, comprise system host and sampling module, it is characterized in that: described main frame is a kind of integrated host, described main frame is connected with controller of fan, blower fan, audible-visual annunciator, infrared inductor in addition, and described blower fan is to be connected with main frame by controller of fan; Described sampling module is made of gas sensor and temperature/humidity sensor.
The sampling module that described main frame connects is minimum to be one, mostly is 20 most.
The blower fan that described controller of fan output connects is minimum to be one, mostly is 21 most, and each loop load electric current is less than 3.5A.
