Abstract
The utility model relates to an oil level gauge for a transformer oil conservator. An oil conservator is provided with a cylindrical shell and arranged horizontally; the oil level gauge for the transformer oil conservator is characterized in that the center of one end of the shell is provided with a super large dial gauge, and the circumference of the dial gauge is marked with temperature symbols and oil level scales, and the pointer of the oil level gauge is arranged at the circular centre; an oil chamber in the shell is internally provided with a displacement transfer structure with 90 degrees of mechanical turning: a teeth bar is arranged in the bellows and connected with the bellows; and a spur gear (4) is arranged on the teeth bar (3), and a bevel gear (5) coaxial with the spur gear (4) is meshed with a bevel gear (5') coaxial with the oil gauge pointer (2), and the horizontally-displacing flexible teeth bar (3) drives the spur gear (4) to rotate and changes the direction through a pair of bevel gears, so that the displacement of the flexible teeth bar (3) is converted into the movement of the oil gauge pointer (2) on the dial (1), and an electronic element connected with a displacement converting circuit (9) is respectively arranged on the spur gear (4) and the bevel gear (5'), and the displacements of the bellows and the teeth bar (3) are converted into 4-20mA of analog quantity through the circuit (9) to output and transfer to a remote monitoring device and a display. The rotation of the gear is converted into the swinging of the pointer on the dial gauge through the coaxial pointer, meanwhile the circuit processing displacement distance is combined with a mechanical structure to enable the analog quantity to be consistent with the mechanically transferred distance and visually displayed on the surface of the shell by using the pointer corresponding to displacement and temperature. The super large dial gauge is convenient for distant surveillance.
Description
Technical field
The utility model 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 utility model provides a kind of oil level gauge for transformer oil storage cabinet, and 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.
