Abstract
The invention relates to an oil level gauge of a transformer oil conservator, comprising a shell which is a circular cylinder oil conservator and is arranged horizontally. The oil level gauge is characterized in that center of one end of the shell is provided with an extra-large dial gage, temperature signs and oil level scales are marked at the periphery of the dial gage, a pointer of the oil level gauge is arranged at the center of the circle; a 90-degree mechanical steering displacement-conveying mechanism is arranged in an oil chamber of the shell; a rack is arranged in a bellows and is connected with the bellows, a straight gear (4) is arranged on a rack (3), a bevel gear (5) coaxial with the straight gear (4) is meshed with a bevel gear (5') coaxial with an oil meter pointer (2), a flexible rack (3) of horizontal displacement drives the straight gear (4) to rotate and changes directions by the two bevel gears, displacement distance of the flexible rack (3) is converted to movement of the oil meter pointer (2) on the dial gage (1); an electronic element is respectively arranged on the straight gear (4) and the bevel gear (5') to be connected with a displacement converting circuit (9), the displacement distance of rack (3) and the bellows is converted to 4-20mA analog quantity by the circuit (9) and the analog quantity is output and transmitted to a remote monitoring device and a monitor. Rotation of the gear is converted into swing of the gear by coaxial pointers on the dial gage, and circuits and mechanical structures for disposing the displacement distance are combined, so that analog quantity is consistent with mechanical conveying distance; on the surface of the shell, the pointer corresponding to displacement and temperature is used for visual display, and the extra-large dial gage facilitates long-distance observation.
Description
Technical field
The present invention relates to power transformating and supplying facility, a kind of oil level gage that is used on the transformer oil conservater.
Background technology
Oil level gauge for transformer oil storage cabinet is the conventional products of widespread usage in power transmission and transformation system, and the demonstration of regulation oil level gage is wanted accurately in the national sector standard " JB/T10692-2007 ", and oil level gage is oil-tight, water-tight.That the useful box chi of oil level gage on the present market is changed a social system, useful common pointer oil level gage.More than the oil level gage of two kinds of forms all exist serviceable life short, oil level shows problems such as inaccurate.
Along with the development of power transmission and transformation industry, the serviceable life of oil level gauge for transformer oil storage cabinet, the accuracy of oil level demonstration and the requirement of other function have all been improved greatly.As the serviceable life of the oil level gage that transformer is shielded, the accuracy of oil level demonstration and the distant place transfer function of oil level signal is the problem that needs solution.
Summary of the invention
The purpose of this invention is to provide a kind of oil level gauge for transformer oil storage cabinet, the pointer oil level gage of super large indication dial plate has temperature demonstration, the warning of high low oil level and remote monitoring function.
Oil level gauge for transformer oil storage cabinet, housing are tubular oil conservater horizontal positioned, it is characterized in that there is super large indication dial plate at housing one end center, and the dial plate circumference indicates each section temperature symbol and oil level scale, and the pointer of oil level gage places the center of circle; Establish 90 ° of displacement transferring structures of mechanical steering in the grease chamber in the housing: the bar tooth is placed in bellows interior and links to each other with corrugated tube, on the bar tooth spur gear is set, the conical gear and with oil meter pointer coaxial conical gear engagement coaxial with spur gear, the moving spur gear of the flexible strip cingulum of horizontal shift rotates, and by the conical gear conversion direction, the shift length of flexible strip tooth is converted to oil meter pointer moving on dial plate; And on spur gear and umbrella tooth, all settle the electron displacement induction pieces, the displacement of corrugated tube and bar tooth is converted to the output of 4～20mA analog quantity and passes to long-distance monitorng device, display by set analog conversion circuit.
The design's transformer wavy metal formula oil conservater, have 4～20mA teletransmission function, the band temperature shows, be with high low oil level to report to the police and super large indication dial plate and pointer, outstanding contributions move the motive power that is converted to initial wheel with (level) about producing because of the temperature variation bellows expansion, and on dial plate, the rotation of gear is transferred to the swing of pointer by coaxial pointer, the circuit that to dispose shift length simultaneously combines with physical construction, make the consistent of analog quantity and mechanical transfer apart from both, show intuitively with the displacement pointer corresponding that at surface of shell super large indication dial plate makes things convenient for distant surveillance with temperature.In the pulpit, dispose electronic display, circuit is provided with the compensation debugging functions, be implemented in that oil level in the monitor of the outer and remote control room of cabinet, temperature are corresponding consistent shown constantly and calculate innage in the oil conservater, made things convenient for like this measurement of transformer motion state and the unified supervision of Long-distance Control of heavy wool cabinet; And longer service life.
