Description

A kind of oil level gauge for transformer with warning function

Technical field

The utility model relates to device for transformer field, specifically, specially refers to a kind of oil level gauge for transformer with warning function.

Background technology

Be arranged at present on oil-immersed full-sealed transformer, the oil level indicator that shows its oil level mainly contains two kinds, the first oil level indicator is to have inspection hole on a metal tube, and sealing is equipped with the observation glass tube of oil level or the parts of glass plate on inspection hole, in metal tube, there is float more easy to identify, for example float is red color, and the position that float shows is the position of pasta.But inspection hole is higher than fuel tank cap upper surface, and when oil level approaches case lid position, float is shown as without oil, can not accurately show the minimum oil level of fuel tank internal upper part.

The second oil level indicator is on float, to be equipped with the mark part that shows oil level mark, has solved better the inaccurate problem of minimum oil level that shows fuel tank internal upper part.The second oil level indicator is equipped with valve part, also can exit, gather gas sample, earth pressure release etc.

Above-mentioned two kinds of oil level indicators can only observe the position of transformer oil, cannot Realtime Alerts.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.

Referring to Fig. 1, a kind of oil level gauge for transformer with warning function described in the utility model, comprises transformer-cabinet and detection components.

Described detection components comprises pedestal, inserting tube, suspension type sensor 110 and instrument 120; Described pedestal is installed on transformer-cabinet, the below of pedestal is stretched into by inserting tube on the transformer oil of transformer-cabinet inside, the bottom of described inserting tube has axial through hole, described suspension type sensor 110 is arranged in this through hole, described instrument 120 is installed on the surface of transformer-cabinet, and the input end of instrument 120 is electrically connected with the signal output part of suspension type sensor 110;

Also comprise alarm assemblies; Described alarm assemblies comprises comparer 130, gauge tap 140, acoustical generator 150 and warning lamp 160; The signal output part of described suspension type sensor 110 is connected with the signal input part of comparer 130, the output terminal of comparer 130 connects gauge tap 140, described acoustical generator 150 and warning lamp 160 are installed on the surface of transformer-cabinet, and described gauge tap 140 is installed on the power circuit of acoustical generator 150 and warning lamp 160.

Principle of work of the present utility model is as follows:

The suspension type sensor 110 that is positioned at inserting tube detects the position of transformer transformer oil in real time, and it is transferred to respectively to instrument 120 and comparer 130, wherein, instrument 120 shows the position of transformer oil intuitively, the position signalling of transformer oil is converted to analog voltage signal by comparer 130, and compare with the normal voltage of comparer 130 inside, if analog voltage signal is less than normal voltage, comparer 130 makes the power circuit of acoustical generator 150 and warning lamp 160 become path by gauge tap 140, sends warning light and alarming sound.

More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
