The utility model discloses on instruction of current oil level and pressure relief valve basis, increase oil level and temperature sensing function, be electric output with oil level and temperature transducer for transformer oil position, temperature, pressure sensor integration had both had traditional oil level instruction function, pressure release function, had oil level, temperature and pressure sensing function again, simple to operate.
Description
Technical field
This utility model is related to oil-filled transformer field, more particularly, to a kind of oil-filled transformer oil level temperature, pressure one
Body formula sensor.
Background technology
At present, people are during using oil-immersed type transformer, when transformer station high-voltage side bus for a period of time after, the immersion oil amount of transformator
Will reduce, if the immersion oil amount of transformator is very few, the iron core of transformator and coil will be overheated, and then affect transformator
Normal operation, even results in transformator and burns.For this reason, people are in order to be able to know the immersion oil amount of transformator in time, often using oil
Position meter, to measure the immersion oil amount in oil-immersed type transformer, oil level indicator is installed to inside transformer, when immersion oil amount is very few, oil level indicator
Buoy will decline, the instruction on body also accordingly reduces buoy instruction device immediately, people be available for buoy instruction dress
Put the immersion oil amount knowing inside transformer, to point out staff to add oil mass in time.
The product sensor of existing oil-filled transformer has oil level display transformer and the temperature transmitter of independent function, main
It is used for more than 2500 kilovolt-amperes transformators, composite price is high, transformator needs individually designed mounting interface and position.To 1500
Oil-immersed distributing transformer below kilovolt-ampere, the oil level display transformer product being no suitable for.
Utility model content
The purpose of this utility model is to provide a kind of oil-filled transformer oil level temperature, pressure integral sensor, to solve
Certainly above-mentioned technical problem.
Technical problem to be solved in the utility model employs the following technical solutions to realize：
A kind of oil-filled transformer oil level temperature, pressure integral sensor it is characterised in that：Including cylindrical shell
Body, is coaxially arranged with glass tubing inside shell body, glass tubing has been inserted into aluminum pipe, and aluminum pipe upper end connects buoy instruction device, institute
State aluminum pipe lower end and connect floating cylinder, the upper end of floating cylinder is fixed with magnet ring, described shell body upper end setting pressure relief valve is described
Watch window is provided with shell body, described shell body is also cased with the outer sensor housing of annular, outer sensor housing is opened
It is provided with through hole, be provided with pressure transducer and temperature sensor in described sensor outer housing body, in the circumferential wall of described shell body
It is additionally provided with seven core aviation sockets.
Pass through ring-shaped rubber flat gasket between described shell body upper end and pressure relief valve.
It is covered with support, pedestal upper end is connected with shell body lower end outside described floating cylinder.
Described buoy instruction device adopts color instruction, pointer instruction or graduation indication.
On shell body, the watch window of setting and glass tubing are combined into window, are easy to observe buoy instruction device, thus
Oil level can intuitively be judged.
Floating cylinder under buoyancy, and according to oil level change carry out under fluctuate, and by buoy instruction device show
Show that oil level changes, pressure relief valve is arranged on shell body upper end, pressure release, replacing are convenient.
The beneficial effects of the utility model are：
This utility model, on the basis of the instruction of existing oil level and pressure relief valve, increases oil level and temperature sensing function, will
Oil level and temperature transition be electric signal output so that transformer oil level, temperature, pressure sensor integrated, both there are traditional oils
Position instruction function, pressure relief function, have oil level, temperature and pressure sensing function again, easy for installation.
It is applied to less than 1500 kilovolt-amperes oil-immersed distributing transformers.
