Abstract
The utility model relates to the field of power transformer manufacture, and discloses a capsule type oil conservator suitable for a large transformer. An oil level indicator floater connected with an oil level gauge is arranged in the capsule type oil conservator and is a solid ball body. The capsule type oil conservator ensures that the floater is not deformed during the continuous vacuuming process, and therefore ensures that an oil level indicator of the oil conservator normally and reliably indicates the oil level of the transformer body after the transformer is manufactured.
Description
Technical field
The utility model relates to power transformer and makes field, particularly a kind of capsule type oil storage cabinet that is applicable to high-power transformer.
Technical background
In the transformer production process and during on-the-spot the installation, body oil conservator oil level indicator pointer usually can occur and be designated as zero situation.Thereby be forced to do over again, have influence on the normal production of transformer or installation progress, caused the waste of human and material resources.
Employed domestic oil level indicator float on the Domestic Transformers capsule type oil storage cabinet in the transformer vacuum, because the pressure variation is too fast, causes ball float to hit flat and connecting rod bending at present, has a strong impact on the manufacturing of transformer subsequent production and use.
Summary of the invention
The purpose of this utility model is to provide a kind of capsule type oil storage cabinet that is applicable to high-power transformer, can effectively save cost, reduces oil level indicator float repair rate, improves transformer oil level metering accuracy.
For reaching above purpose, the utility model takes following technical scheme to be achieved.
A kind of capsule type oil storage cabinet that is applicable to high-power transformer is provided with the oil level indicator float that is connected with oil level gauge in the described capsule type oil storage cabinet, this oil level indicator float is the filled circles spheroid.
Further improvement of the utility model and characteristics are:
Described oil level indicator float is the vinyon material, with transformer oil melt and dissolved reaction does not occur;
Described oil level indicator float is provided with the aluminium alloy screw nipple, is used for being connected of oil level indicator float and oil level gauge;
The aluminium alloy screw nipple that arranges on the described oil level indicator float is connected with oil level gauge by the oil level indicator connecting rod.
Compared with prior art, the utility model oil conservator has the following advantages: the utility model oil level indicator float is the filled circles sphere structure, in the process that vacuumizes, even it is too fast that pressure changes, the phenomenon that ball float hits flat and connecting rod bending does not occur yet, thereby guarantees the in working order normal liquid level of lower demonstration of oil conservator oil level gauge.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 is the structural representation of the utility model capsule type oil storage cabinet;
Fig. 2 is the structural representation of the utility model oil level indicator float.
Embodiment
With reference to Fig. 1, a kind of capsule type oil storage cabinet 1, be provided with oil level gauge 5, oil level indicator float 3, oil level indicator connecting rod 4 in the described capsule type oil storage cabinet, be provided with aluminium alloy screw nipple 31 on the described oil level indicator float, described aluminium alloy screw nipple 31 is connected with the oil level indicator connecting rod, and described oil level indicator connecting rod is connected with oil level gauge.Described oil level indicator float 3 adopts the vinyon material, with transformer oil melt and dissolved reaction does not occur, and form is the filled circles spheroid, in the process that vacuumizes continuously, can guarantee that float is indeformable.
During assembling, the aluminium alloy screw nipple on the utility model float and oil level indicator connecting rod are linked, be connected with oil level gauge again, be installed in the capsule type oil storage cabinet, by the transformer technological requirement capsule type oil storage cabinet is evacuated to negative pressure.
In the whole process that vacuumizes, with reference to the structure of Fig. 2, can guarantee that float is not affected by vacuum and produces distortion, thereby guaranteeing that the oil conservator oil level gauge is lower in working order shows normal liquid level.
Claims (4)
