Background technology
The shelf depreciation of transformer is the one of the main reasons causing Electric Power Equipment Insulation deterioration, discharges at every turn, the impact of high-energy electron or acceleration electronics, and particularly long-term shelf depreciation effect all can cause physical influence and the chemical reaction of various ways.During as charging point shock bubble outer wall, just may interrupt the chemical bond of medium, destroy the molecular structure of medium, cause insulation degradation, accelerate insulation breakdown process, likely cause equipment failure time serious, even affect the normal operation of electrical network.Therefore, transformer, as one of the visual plant of electric system, is necessary to monitor it.
Transformer reaches the object of insulation, arc extinguishing, cooling by mineral oil simultaneously, in the course of the work, due to the reason such as overheated, electric discharge, arcing, will form splitting action to mineral oil, produces the fault characteristic gases such as carbon monoxide, hydrogen, acetylene.Therefore, by monitoring the information such as concentration, variation tendency of these fault characteristic gases, can assess the duty of relevant device.In prior art, transformer needs to get oil and monitoring shelf depreciation situation by two complete equipments, and existing get oily device get hydraulic fluid port generally higher than partial discharge monitoring device, this makes the high-land of getting hydraulic fluid port, the oil dissolved gas situation of taking out can not reflect the duty of transformer exactly, and making the monitoring cost needed for transformer high, consumes resources is large.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of cost low, can get simultaneously oil and Real-Time Monitoring partial discharge of transformer situation there is the transformer partial discharge on-Line Monitor Device of getting functional oil.
For this reason, the technical solution of the utility model is: have the transformer partial discharge on-Line Monitor Device of getting functional oil, it is characterized in that: sensor is put in its office of comprising, data processing unit and oil chromatography device are put in sensor connecting piece, ejector sleeve, oil-release valve, oil return valve, office; Described oil-release valve is arranged on below transformer body, and oil-release valve outer end has the first flange-interface, and centre has the cylindrical port connected with the port in transformer body; Described office puts transducer tip and has wire, and wire end has conducting wire connector; Described conducting wire connector lower end has concentric cable access port, and conducting wire connector puts data processing unit by the concentric cable office of being connected to; The described ejector sleeve office of being enclosed within puts on the wire of sensor, and sensor is put in ejector sleeve front end connection office, and end connects conducting wire connector; Described sensor connecting piece is enclosed within ejector sleeve, and sensor connecting piece front end has the second flange-interface; Described office puts sensor and stretches in transformer body port by the cylindrical port of oil-release valve, and the first flange-interface on the second flange-interface of sensor connecting piece front end and oil-release valve is bolted; Described sensor connecting piece lower end has one and gets oily interface, gets oily interface and connects oil chromatography device by getting oil pipe; Described oil return valve is arranged in transformer body, is positioned at above oil-release valve; Described oil return valve has an oil return interface, oil return interface connects oil chromatography device by scavenge pipe.
During utility model works, office is put sensor and put in the cylindrical port of oil-release valve, be enclosed within by sensor connecting piece on ejector sleeve, sensor connecting piece can slide along ejector sleeve; The second flange-interface on sensor connecting piece and the first flange-interface on oil-release valve are bolted; Promote ejector sleeve, make the office of ejector sleeve front end put sensor and be deep in the port of transformer body along the cylindrical port of oil-release valve.The information that sensor will receive in transformer body is put in office, and the concentric cable office of being sent to connected by conducting wire connector puts in data processing unit, carries out information processing.Oily interface of getting simultaneously on sensor connecting piece is connected with oil chromatography device by getting oil pipe, mineral oil in transformer body can be transported in oil chromatography device and carry out gas-oil separation process, and the mineral oil after gas-oil separation is got back in transformer body by the oil return interface of scavenge pipe from oil return valve.The utility model, by increasing oil-out on partial discharge monitoring device, makes it to have the function of getting oily device concurrently simultaneously, reduces the production cost of transformer monitoring device.Meanwhile, the physical features of oil-release valve is low, and the oil pressure of oil-out is high, and oil dissolved gas is more true, can reflect the duty of transformer exactly.
