Background technology
Transformer is directly connected to safe operation and the serviceable life of electrical equipment by the quality of insulating oil performance.And the sulfide in insulating oil for transformer can form cuprous sulfide copper coil is produced to corrosive attack in transformer operational process on insulating paper.First this sulfide can make the insulating property of insulating paper reduce, and cause the insulating paper of transformer breakdown, thereby it is damaged to cause transformer.So, strengthen the supervision of active sulfur in insulating oil to detect outstanding aobvious necessary.But, up to the present, in insulating oil the detection of active sulfur still adopt traditional ASTM D (wherein " ASTM " be English full name is the abbreviation of " American Society for Testing and Materials ", and its Chinese translation is " American Society Testing and Materials "; " D " is Sort Code, mean and comprise petroleum products, and fuel, low strong plastics are at the code of interior material.) 1275 quilitative methods, or IEC (English full name is the abbreviation of " International Electro technical Commission ", and its Chinese translation is " International Electrotechnical Commission ".) (German full name is the abbreviation of " Deutsches Institut f ü r Normung e.V. ", and its Chinese translation is " meeting of DIN chemistry " for 62535 quilitative methods, DIN.) (wherein " GB " is the abbreviation of Chinese pinyin " GUO JIA BIAO ZHUN ", and its Chinese is " national standard ", and " T " represents to recommend for 51353 quilitative methods, GB/T.) 25961 quilitative methods.Above-mentioned these traditional quilitative method ubiquities length consuming time, inefficient defect.For example the judgement of test findings is mainly relied on to the intuitive judgment to color, therefore cannot give quantificational description to the corrosive nature of oil product.For insulating oil corrosion condition being carried out to the accurate judgement that quantizes, be extremely necessary to design as early as possible a kind of device and the using method thereof of transformer with active sulfur content in insulating oil that detect, to provide safeguard for the safe operation of electrical equipment.
Utility model content
The technical problems to be solved in the utility model is, the defect existing for prior art, provides a kind of active sulfur content detection device, and this device is applicable to the quantitative detection with active sulfur content in insulating oil to transformer, and simple in structure, easy to carry.
The technical solution of the utility model is that described active sulfur content detection device, referring to Fig. 1, includes a rectangular box 2 with draft tube 1 and escape pipe 5, and an oscillator 6 with frequency counter.In wherein said casing 2, be also provided with a thermal detector 3, well heater 4 and a sensor stand 8.Described thermal detector 3 and well heater 4 install respectively in the upper bottom surface both sides of casing 2 inner chambers, and described sensor stand 8 is placed on the bottom surface of casing 2 inner chambers.A slice quartz crystal resonance piece 7 is installed in this sensor stand 8, and this quartz crystal resonance piece 7 is connected with the wire of output terminal of the above-mentioned oscillator 6 with frequency counter.In addition, above-mentioned escape pipe 5 connects and is connected with casing 2 upper ends; Above-mentioned draft tube 1 connects and is connected with casing 2 lower ends.
, get and entrust transformer insulating oil sample application used on quartz crystal resonance piece 7 for detection of in transformer oil when active sulfur content by the active sulfur content detection device of the present utility model forming with upper member.This quartz crystal resonance piece 7 is inserted on the sensor stand 8 in casing 2, be connected with peripheral hardware electrochemical quartz crystal microbalance testing workstation by wire.Open draft tube 1 and escape pipe 5, input nitrogen through draft tube 1, after closing draft tube 1 and escape pipe 5 after being full of, the oscillator 6 of startup with frequency counter records frequency f 1 and the interior temperature of casing 2 of quartz crystal resonance piece 7, heater 4 keeps the interior temperature of casing 2 0.5~10h between 90~150oC, then close well heater 4, when the temperature that recorded, record the frequency f 2 of quartz crystal resonance piece 7 before the interior temperature of casing 2 drops to heater 4; Conventional method calculates the frequency change Δ f of test front and back quartz crystal resonance piece.Conventional method calculates the mass change Δ m of test front and back quartz crystal resonance piece again, can draw the content of entrusting active sulfur in transformer insulating oil used.
The beneficial effects of the utility model are, use this device can easily and accurately quantitatively detect the content of transformer with active sulfur in insulating oil, device is simple, easy to operate, is of great significance for latency fault and the repair based on condition of component tool of carrying out transformer of diagnosis transformer.
