Description
Technical field：
It the utility model is related to a kind of micro- water detection means of sulfur hexafluoride breaker.
Background technology：Moisture content overproof threatens the safe operation of equipment and power network in SF6 breakers, it is necessary to which it is carried out
Accurate measurement and strict control.
The content of the invention：
The purpose of this utility model is to provide a kind of micro- water detection means of sulfur hexafluoride breaker.
Above-mentioned purpose is realized by following technical scheme：
A kind of micro- water detection means of sulfur hexafluoride breaker, its composition include：SF6 breakers, described SF6 breakers point
Be not connected with operating mechanism and density monitor, one end of described SF6 breakers by threeway tracheae respectively with SF6 scavenging air valves
Door connects with automatic valve, and described automatic valve absorbs air chamber with sensor and is connected, and described sensor absorbs air chamber and inspection
Examining system is connected, and described detecting system is connected with host computer.
The micro- water detection means of described sulfur hexafluoride breaker, described sensor absorb air chamber have O-ring seal and
Fibre optical sensor, described O-ring seal are connected with filter lens and collimating mirror, are connected with the inside of described fibre optical sensor
Silica fibre.
The micro- water detection means of described sulfur hexafluoride breaker, described sensor, which absorbs air chamber, has air inlet and outlet
Mouthful.
The beneficial effects of the utility model：
1. the utility model SF6 gas micro water contents detecting system needs from scene extraction vapour concentration and is converted into telecommunications
Number, this characteristic signal is pre-processed, is transmitted, is calculated, judged and shown to complete whole monitoring process.
It is the very high air chamber of a sealing property that the utility model sensor, which absorbs air chamber, and it is attached directly to SF6 breaker gas
Room.Gas is extracted into every 48 hours by sensor by automatic valve and absorbs air chamber.Fibre optical sensor enters the signal of detection immediately
Row conversion and processing, and it is sent to host computer.Host computer judges whether SF6 breakers water content exceedes operation standard.Work as SF6
When the water content of breaker exceedes operation standard, detecting system will alarm, and staff is according to circumstances to the gas in SF6 breakers
Body is changed.In material selection, light source is mainly done using semiconductor laser.
The utility model application all optical fibre structure carries out Concentration Testing to micro- water in SF6 breakers.With measurement accuracy
Height, reaction speed is fast, the advantages that strong antijamming capability.To effectively improving SF6 breaker utilization rates, and reasonable arrangement work people
Member changes the foundation that gas provides strong guarantee and science.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation that sensor absorbs air chamber.
Embodiment：
Embodiment 1：
A kind of micro- water detection means of sulfur hexafluoride breaker, its composition include：SF6 breakers 1, described SF6 breakers
Be connected respectively with operating mechanism 2 and density monitor 3, one end of described SF6 breakers by three breather pipes 4 respectively with SF6
Ventilation valve 5 and automatic valve 6 connect, and described automatic valve absorbs air chamber 7 with sensor and is connected, and described sensor absorbs
Air chamber is connected with detecting system 8, and described detecting system is connected with host computer 9.
Embodiment 2：
The micro- water detection means of sulfur hexafluoride breaker according to embodiment 1, described sensor, which absorbs air chamber, has O
Type sealing ring 10 and fibre optical sensor 11, described O-ring seal are connected with filter lens and collimating mirror 12, and described optical fiber passes
Silica fibre 13 is connected with the inside of sensor.
Embodiment 3：
The micro- water detection means of sulfur hexafluoride breaker according to embodiment 1 or 2, described sensor absorb air chamber tool
There are air inlet and gas outlet.
Embodiment 4：
Spectrum Absorption Principle
The Infrared absorption spectrum of measurement gas molecule is the effective means for identifying gas molecule and measuring gas volume fraction.
Different gas has different FTIRs, the chemical constitution difference of gas molecule.
Embodiment 5：
The design of sensor
Optical fiber is only used as transmission medium in Infrared spectra adsorption type gas detecting system, and the sensing element of system is sensing
Device absorbs air chamber.Because the water content in SF6 breakers is smaller, and use the absorption air chamber of transmission-type.Transmission-type absorbs gas
Room is made up of filter lens, collimating mirror, silica fibre, makes the sensitivity of sensor strengthen.
