Abstract
The utility model relates to a metal bellow type oil conservator for a transformer. An oil conservator shell and metal bellows form a hermetical oil chamber of the oil conservator; the metal bellow type oil conservator for the transformer is characterized in that 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; the pointer of the pointer oil level gauge is arranged at the centre of a circle; the oil chamber in the shell is provided with an displacement transfer structure with 90 degrees of mechanical turning: a teeth bar is arranged in the bellows and connected with the bellows; the horizontally displaced flexible teeth bar drives a spur gear, and a bevel gear coaxial with the spur gear to be meshed with a bevel gear coaxial with an oil gauge pointer, so that the displacement of the flexible teeth bar is converted to the movement of the oil gauge pointer on the dial; an electronic displacement inducting member is arranged at a driving wheel on the teeth bar; and the displacement of the bellows is converted to 4-20mA of analog quantity through the arranged circuit to output. The metal bellow type oil conservator for the transformer has advantages that the oil level displacements influenced by temperature are gathered and transferred by mechanical structure, simultaneously, intuitively represented by the pointer corresponding to the displacement and temperature at the shell surface; the super large dial gauge is convenient for distant surveillance; an electronic display unit and a long distance transmission electronic unit are provided to realize the purpose of displaying the oil level, and temperature at the external of the oil conservator body and in the monitor of remote control room, which is more convenient for remote control and uniform supervision of a plurality of oil conservators.
Description
Technical field
The utility model relates to the loaded switch oil conservator of power transformating and supplying facility, transformer wavy metal formula oil conservator.
Background technology
Transformer is the conventional products of widespread usage in power transmission and transformation system with wavy metal formula oil conservator, the pressure test that regulation oil conservator cabinet should be able to bear 50kPa in the national sector standard " JB/T6484-2005 ", and lasting 30min answers ne-leakage; The oil conservator core body should be able to bear the leakage test that vacuum degree is not more than 50Pa, continues 30min, seepage must not be arranged and permanent deformation takes place; The demonstration of oil level gauge is wanted accurately, and oil level gauge is oil-tight, water-tight.That the useful box chi of oil conservator oil level gauge on the present market is changed a social system, useful common pointer oil level gauge.More than the oil level gauge of two kinds of forms all exist useful life short, oil level shows problems such as inaccurate.
Along with the development of power transmission and transformation industry, requirements at the higher level are proposed for the useful life of transformer oil conservator, the configuration of oil conservator, the accuracy of oil conservator oil level demonstration and the distant place transfer function of oil level signal.
Summary of the invention
The purpose of this utility model provides a kind of transformer wavy metal formula oil conservator, and the accuracy that oil level shows is higher, distant place transmission more convenient collection and the control to oil level signal of oil level signal.
A kind of transformer wavy metal formula oil conservator, oil conservator housing and metal bellows constitute hermetic oil conservator grease chamber, it is characterized in that housing one end has super large indication dial plate, the dial plate circumference indicates temperature symbol and oil level scale, and the pointer of pointer oil level gauge 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 bellows, the flexible strip cingulum of horizontal displacement move spur gear, with coaxial bevel gear of spur gear and the bevel gear engagement coaxial with the oil meter pointer, the displacement of flexible strip tooth is converted to oil meter pointer moving on dial plate; And the initiating wheel place on the bar tooth settles the electron displacement induction pieces, by set circuit the displacement of bellows is converted to the output of 4～20mA analog quantity.
The design's transformer wavy metal formula oil conservator, have 4～20mA teletransmission function, the demonstration of band temperature, be with high low oil level to report to the police and super large indication dial plate and pointer, outstanding contributions are that oil level displacement with cabinet internal cause variations in temperature is with mechanical structure collection and transmission, the soft copy that to dispose displacement simultaneously combines with mechanical structure, make both unanimities, 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.Also dispose the remote transmission electronic building brick simultaneously, in the control room, dispose electronic display, circuit is provided with the compensation debugging functions, be implemented in oil level, the corresponding consistent demonstration of temperature in the monitor of the outer and remote control room of cabinet, the unified of more convenient Long-distance Control and heavy wool cabinet supervised.

Fig. 2 is the oil conservator end view that the design's super large indication dial plate is arranged;
Embodiment
A kind of transformer wavy metal formula oil conservator, oil conservator housing 1 and metal bellows 2 constitutes hermetic oil conservator grease chamber, cover plate for manhole 4 is arranged in an end of bellows 2, be useful in the bottom of oil conservator the dirty feculence box 6 of collection with the pipe joint 7 that is used to annotate, drain the oil, be used for the square steel that the cabinet pin 8 that is connected with transformer and valve 9, the lateral middle in the cabinet both sides have been useful on booster action; It is characterized in that housing 1 other end has super large disk indication dial plate 5, the dial plate circumference indicates each section temperature symbol-30 ℃-+90 ℃ and oil level scale, and the pointer of oil level gauge places the center of circle; Establish 90 ° of displacement transferring structures of mechanical steering in the housing in the grease chamber: the bar tooth is placed in bellows interior and links to each other in bellows, spur gear is placed on the bar tooth, the flexible strip cingulum of horizontal displacement move spur gear, with coaxial bevel gear of spur gear and the bevel gear engagement coaxial with the oil meter pointer, the displacement of flexible strip tooth is converted to oil meter pointer moving on dial plate; And the initiating wheel place on the bar tooth settles the electron displacement induction pieces, by set circuit the displacement of bellows is converted to the output of 4～20mA analog quantity.
Be used to exit a, bleeder pipe 3 under can drawing is arranged at the oil conservator top.
