Abstract
The invention discloses a transformer on-load tap-changer real-time online oil purifier which is provided with an online oil purifier connected with an on-load tap-changer oil cavity through an oil inlet pipe and an oil outlet pipe. The transformer on-load tap-changer real-time online oil purifier further comprises a filter control device, a dielectric oil dielectric strength test system, a micro water sensor and an online monitoring and controlling device which is connected with a network system in a bus mode and matches with far-end monitoring software to achieve unmanned automatic operation. Dual functions of online oil purifying and real-time monitoring are achieved, the oil purifier is guaranteed to be effectively started in real time, not only is the service life of the oil purifier prolonged, but also clean of dielectric oil is guaranteed, and therefore safety and reliability of operation of an on-load tap-changer are effectively increased, times of blackout overhaul are reduced, overhaul period is prolonged, power supply quality is improved and economic benefit of enterprises is improved.
Description
Technical field
The invention belongs to the oil purifier technical field, be specifically related to a kind of on-load tap changers of transformers real-time online oil purifier, can be used for the on load tap changer of high-power transformer.
Background technology
In recent years, due to electrical network and power consumer more and more higher to the requirement of quality of voltage, in order to guarantee the stable of system power supply voltage, the action of on-load tap changers of transformers is obviously risen, the on load tap changer accident that thereupon occurs also rises year by year.At present, power supply unit is for guaranteeing the on-load tap changers of transformers safe operation, reduce equipment failure rate, regulation according to " DL/T 574-95 on load tap changer operating maintenance guide rule ", when one of following condition satisfies, change oil or oil strain: the every switching of ⒈ loaded switch 5000-10000 time; ⒉ moves 1-2; In ⒊ oil, puncture voltage is lower than 25kV.Power office is recondition expense nearly millions of units over a year, because of personnel not, can't in time overhaul without monitoring means, cause the indirect loss that power outage brings can't estimate especially.Therefore, effectively strengthen on load tap changer workplace safety and reliability, thereby reduce the interruption maintenance number of times, extend the time between overhauls(TBO), improve power supply quality, improve economic benefit and the modern management level of enterprise, low-carbon (LC), energy-saving and environmental protection etc. is had realistic meaning.
At present, the On-line oil filter of installing on the on load tap changer of high-power transformer, its purifier operation control method only has regularly, manually or with the tap changer action starts three kinds of modes, and concrete running time of the interval of On-line oil filter is be determined empirically or move with the random action of tap changer.Although use the effect of the purification insulating oil that this type of On-line oil filter also can reach, but due to running time the interval determine scientific and reasonable not or uncontrolled, On-line oil filter or action are too frequent, shortened the useful life of filter core, increased equipment energy consumption, or action frequency is very few, causes the insulating oil oil product to worsen, insulation property reduce, and cause that Circuits System breaks down.
Summary of the invention
The purpose of this invention is to provide a kind of insulating oil oil product Real-Time Monitoring and in-line purification of integrating, can carry out according to insulating oil oil product Real-Time Monitoring result the on-load tap changers of transformers real-time online oil purifier of On-line Control to the startup of purifier.
for achieving the above object, technical scheme provided by the present invention is: a kind of on-load tap changers of transformers real-time online oil purifier, has an On-line oil filter, On-line oil filter connects load tap changer oil chamber by the turnover oil pipe, it is characterized in that: also comprise and filter control device, dielectric oil dielectrical strength test macro, little water sensor and Online Monitoring Control device, described Online Monitoring Control device by holding wire and dielectric oil dielectrical strength test macro be connected the water sensor signal and be connected, dielectric oil dielectrical strength test macro and little water sensor detect insulating oil according to instruction, testing result feeds back to the Online Monitoring Control device by holding wire, the Online Monitoring Control device is connected with filtration control device signal by holding wire, filter control device and connect On-line oil filter by holding wire, described Online Monitoring Control device is by mode bus interconnection network system, coordinate remote monitoring software to realize the unattended operation automatic operation.
The flowline of described load tap changer oil chamber is provided with the gas air-release mechanism of online venting.
Described On-line oil filter is provided with the Fill valve of realizing online repairing.
Advantage of the present invention is that the purification insulating oil, little oil are monitored, the dielectric strength monitoring is integrated in one, the formation control system, realize the dual-use function of on-line oil cleaning and Real-Time Monitoring, guarantee that oil purifier starts timely and effectively, both improve the useful life of oil purifier, guaranteed again the cleaning of insulating oil.Thereby effectively increase on load tap changer workplace safety and reliability, reduce the interruption maintenance number of times, extend the time between overhauls(TBO), improve power supply quality, improve the economic benefit of enterprise.
The technical indicator that reaches by apparatus of the present invention:
Description of drawings
Fig. 1 is the principle schematic of on-load tap changers of transformers real-time online oil purifier of the present invention.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
As shown in Figure 1, be the principle schematic of a kind of on-load tap changers of transformers real-time online oil purifier provided by the invention, consisted of by On-line oil filter 1, filtration control device 2, dielectric oil dielectrical strength test macro 3, little water sensor 4, Online Monitoring Control device 5 and load tap changer oil chamber 11.described Online Monitoring Control device 5 sends to dielectric oil dielectrical strength test macro 3 and little oil sensor 4 command signal that detects by holding wire 9, 4 pairs of dielectric oil dielectrical strength test macro 3 and little oil sensors detect insulating oil according to instruction, and testing result is fed back to Online Monitoring Control device 5 by holding wire 9, Online Monitoring Control device 5 is connected with filtration control device 2 signals by holding wire, filter control device 2 and connect On-line oil filter 1 by holding wire 10, On-line oil filter 1 connects load tap changer oil chamber 11 by the turnover oil pipe, described Online Monitoring Control device is by mode bus interconnection network system, coordinate remote monitoring software to realize the unattended operation automatic operation.The flowline of described load tap changer oil chamber is provided with the gas air-release mechanism of online venting.Described On-line oil filter is provided with the Fill valve of realizing online repairing.
During use, send to dielectric oil dielectrical strength test macro 3 and little oil sensor 4 command signal that detects by holding wire 9 according to predefined monitoring frequency by Online Monitoring Control device 5; 4 pairs of dielectric oil dielectrical strength test macro 3 and little oil sensors detect insulating oil according to instruction, and testing result is fed back to Online Monitoring Control device 5 by holding wire 9; Online Monitoring Control device 5 judges according to feedack whether insulating oil satisfies instructions for use; If insulating oil does not satisfy instructions for use, send signal by holding wire 8 to filtering control device 2, illustrate that insulating oil does not satisfy instructions for use, need to filter; Filtering control device 2 starts by holding wire 10 instruction On-line oil filters 1, by oil inlet pipe 6, insulating oil is sucked On-line oil filter 1 from load tap changer oil chamber 11, after filtering and removing water treatment, then flow back to load tap changer oil chamber 11 by flowline 7; If insulating oil satisfies instructions for use, continue to wait for next group feedback signal.
