Abstract
The utility model discloses a transformer oil level indicator, which comprises an oil level indicator casing, wherein a pointer is arranged in the oil level indicator casing in a sealing mode, a floater which is connected on the pointer through a connecting rod is arranged on the outside of the oil level indicator casing, and the oil level indicator casing is fixedly connected with a transformer oil tank through an installing plate. According to the transformer oil level indicator, the size is small, the structure is simple, due to the fact that the oil level indicator casing is connected with the transformer oil tank, the assembling, disassembling and maintenance are convenient, besides, the sealing effect is good, and the reliability of the oil level indicator is improved.
Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of transformer oil level meter.
Background technology
Transformer oil level indicating device is widely used on the large-scale oil tank for oil immersion type transformer, in order to show the variation of fuel tank internal oil level.
At present, the most widely used transformer pointer type fuel level indicator of China is closed by ball float, fork, gear drive, magnetic misfortune and parts such as housing are formed.When liquid level in the oil conservater is being expanded with heat and contract with cold or after reason such as leakage changed, ball float was followed liquid level and moved up and down.Moving up and down through gear train drive pointer of ball float forwards on the different positions, makes the interior oil level of fuel tank change and can on the dial plate of oil level indicator, accurately show.Wherein the housing of oil level indicator is an aluminum casting; Two groups of magnet are housed in the chamber of housing; Ball float rotates one group of magnet through fork driven gear mechanism, and closes principle through the magnetic misfortune and drive another group magnet and rotate, and the indicator that this group magnet connects oil level indicator rotates pointer to carry out the oil level demonstration.But in long-term application process, find; There is defective in the mechanism of the transformer oil level meter of said structure: the housing of existing transformer oil level meter is by the Birmasil moulding; This molding mode is prone to make aluminum casting to have defectives such as pore, sand holes, shrinkage cavity, to the sealing effectiveness formation potential threat of product.
The utility model content
The technical matters that the utility model mainly solves provide a kind of simple in structure, volume is little, the transformer oil level meter of easy installation and removal, good sealing effect.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of transformer oil level meter is provided; Comprise the oil level indicator housing; Sealing is provided with pointer in the said oil level indicator housing, and the oil level indicator housing is outside equipped with through connecting rod and is connected the float on the pointer, and said oil level indicator housing is fixedly connected with oil tank of transformer through installing plate.
In preferred embodiment of the utility model, be fixedly connected through some register pins between said oil level indicator housing and the installing plate.
In preferred embodiment of the utility model, be provided with O-ring seal between said oil level indicator housing and the installing plate.
In preferred embodiment of the utility model, said oil level indicator housing is the square casing that aluminium alloy is processed.
In preferred embodiment of the utility model, said installing plate is an aluminium alloy plate, and is identical with the oil level indicator shell dimension.
The beneficial effect of the utility model is: the utility model transformer oil level meter volume is little, simple in structure; The oil level indicator housing is connected with oil tank of transformer through installing plate, and installation and removal are very convenient, are beneficial to maintenance; And good sealing effect has improved the reliability of oil level indicator.
Description of drawings
Fig. 1 is the perspective view of the utility model transformer oil level meter one preferred embodiment;
Fig. 2 be shown in the front view of transformer oil level meter;
The mark of each parts is following in the accompanying drawing: 1, oil level indicator housing, 2, pointer, 3, connecting rod, 4, float, 5, installing plate, 6, register pin, 7, O-ring seal, 8, oil tank of transformer.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of transformer oil level meter; Comprise oil level indicator housing 1; Sealing is provided with pointer 2 in the said oil level indicator housing 1, and oil level indicator housing 1 is outside equipped with through connecting rod 3 and is connected the float 4 on the pointer 2, and said oil level indicator housing 1 is fixedly connected with oil tank of transformer 8 through installing plate 5.
Be fixedly connected fixation, easy installation and removal through some register pins 6 between said oil level indicator housing 1 and the installing plate 5.
Be provided with O-ring seal 7 between said oil level indicator housing 1 and the installing plate 5, make and defectives such as pore, sand holes, shrinkage cavity, good sealing effect can not take place between installing plate 5 and the oil level indicator.
The square casing that said oil level indicator housing 1 is processed for aluminium alloy, said installing plate 5 is an aluminium alloy plate, and installing plate 5 is measure-alike with oil level indicator housing 1, and material price is cheap, and installing/dismounting is simple.
During work, the oil level in oil tank of transformer 8 is owing to temperature or other reason raises or reduction, and the float 4 of oil level indicator raises synchronously along with pasta or reduces, because the motion of float 4,2 rotations of drive pointer, the height of indication oil level.
Compared with prior art, the utility model transformer oil level meter volume is little, simple in structure, and oil level indicator housing 1 is connected with oil tank of transformer 8 through installing plate 5, and installation and removal are very convenient, are beneficial to maintenance, and good sealing effect, improved the reliability of oil level indicator.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
