Chinese patent publication number CN101256880A in open day on September 3rd, 2008, discloses a kind of transformer oil conservator, especially a kind of no signal of telecommunication contact finger pin type oil level gauge oil conservator.It has cabinet wall, base plate, cover plate, oil filler plug, oil sample valve, dehydrating breather, dehydrating breather couplet pipe and tube connector etc., has mainly used pointer type fuel level indicator, and pointer type fuel level indicator is installed on the cover board, and the fly rod of pointer type fuel level indicator extend into the inside of oil conservator.But this technical scheme still exists the open type oil conservator to observe in the erecting bed of transformer, can't transmit the real-time change of oil level at a distance, lacks the problem of remote observation.
Summary of the invention
The purpose of the utility model is to solve prior art and can only observes in the erecting bed, can't transmit the problem of the real-time change of oil level at a distance, the open type oil conservator that provides a kind of long-range oil level to show in real time.
The utility model solves the technical scheme that its technical problem adopted: the open type oil conservator that a kind of long-range oil level shows in real time; The cabinet that comprises oil storage; The open type oil conservator that described long-range oil level shows in real time comprises that also digital fuel level sensor, mounting flange and the numeral of the oil level that detects the oil storage in the cabinet show controller; Described digital fuel level sensor is fixedly connected with described cabinet through mounting flange, and the output of said digital fuel level sensor shows that with said numeral the controller communication is connected.This technical scheme is through introducing digital fuel level sensor, and digital fuel level sensor adopts layer scanning technology, the various parameters of dynamic analysis transducer in transformer oil based on the measuring principle of radio frequency electric capacity; Anti-extension oil, anti-oil adhere to, and carry out fine compensation automatically, and precision reaches 0.5%, and oil level is accurately measured; Power consumption is ultralow, is merely 60 milliwatts, changes through transmitter; The control signal of output 4 ~ 20mA and 0 ~ 5V, its teletransmission distance can reach thousands of rice, has reached the needs that remote live shows.
As preferably, the open type oil conservator that described long-range oil level shows in real time also comprises the plane formula oil level indicator, offers on the side of said cabinet to detect mouthful, and said detections mouthful is provided with the plane formula oil level indicator.The setting of plane formula oil level indicator, can the handled easily personnel at the scene the direct labor observe oil conservator, guaranteed field control accurately.
As preferably, described numeral shows that controller is provided with parameter panel is set.Parameter is provided with the setting of panel, can set to report to the police and reminder-data, and operating personnel can show that the indication of controller selects whether carry out follow-up operation, also can carry out the switching displayed of percentage and actual height according to numeral.
As preferably, described numeral shows that controller is provided with the RS485 communication interface.The numeral that is provided with like this shows that controller has telecommunications functions, through RS485 interface and computer carry out at a high speed, bidirectional data exchange efficiently, realize controlling automatically.
As preferably, described numeral shows that controller is provided with and shows the light beam device of oil level actual height and the numeric display unit that shows oil level percentage in real time simultaneously in real time.Be provided with like this, can be user-friendly for real-time monitored.
As preferably, described numeral shows that controller is provided with acoustic-optic alarm.The setting of sound and light alarm can further indicate operating personnel to carry out the subsequent control operation.
The beneficial effect of the utility model is: the utility model reasonable in design; Can show actual height and percentage that oil level changes in real time, can also highly report to the police that operating personnel just can observe the accurate position of oil level intuitively in remote control room in some that set; Can judge that also oil level is whether in prescribed limit; Guaranteed the safe operation of power equipment, it can link to each other with computer through the RS485 interface, realizes control automatically.
