Description
Technical field
The utility model belongs to power equipment monitoring technical field, more particularly to a kind of current transformer oil level monitoring dress
Put.
Background technology
Current domestic 110kV, 35kV current transformer is mostly inverted electric capacity filling type, is set on its expander outer cover
Oil level glass is mostly organic material manufacture, on the one hand, is irradiated for a long time through daylight easy to aging；On the other hand, because being needed during clear wipe
Power failure operation, therefore often can not wipe clearly, the permanent unclear easy laying dust of wiping, cause observation window oil level not see；Furthermore transformer is seen
Examine window and arrange that operating personnel observes oil level by visual observation in the prior art to be high-order, visual difference be present, observation difficulty is big；With
It is inaccurate that upper reason causes current transformer oil level to read, and easily causes the mistake evaluation to transformer state, therefore, needs one kind badly
Current transformer oil level monitoring device, accurate measurements are carried out to the oil level of current transformer.
The content of the invention
For solve in the prior art current transformer because oil level glass is easy to aging, laying dust and observation difficulty it is big caused by oil
Position can not accurate measurements technical problem, the utility model provides a kind of current transformer oil level monitoring device, to realize to electricity
The accurate measurements of current transformer oil level, and monitoring difficulty is reduced, monitoring cost is saved, improves monitoring efficiency.
In order to solve the above technical problems, the utility model provides a kind of current transformer oil level monitoring device, including：Oil level
Detection sensor, battery and signal receive display；Wherein, oil level detection sensor and battery are fixedly installed on current transformer
Top on the inside of outer cover, battery are fixedly connected with oil level detection sensor, and battery uses high-capacity lithium battery, are sensed to oil level detection
Device is powered；Signal receives display and is connected with oil level detection sensor wireless, and signal, which receives, sets switch on display.Signal connects
Receipts display is hand-held.
It is preferred that oil level detection sensor, including：Displacement transducer and signal projector；The output end of displacement transducer
It is connected with the input of signal projector；Displacement transducer is infrared radio formula.
Signal receives display, including：Signal receiver, analog-digital converter, database comparator and display connect successively
Connect；The input of signal receiver and the output end wireless connection of signal projector.Signal receiver receives to be sent out from signal
This simulation displacement signal is converted to digital displacement signal, database comparator by the simulation displacement signal of emitter, analog-digital converter
In store corresponding data between displacement and temperature between current transformer top and expander top, pass through database ratio
Compared with device, digital displacement signal is converted into temperature value, final output is shown over the display.
When current transformer oil level is normal, certain distance be present between top and expander top on the inside of outer cover, due to temperature
Expanded with heat and contract with cold caused by degree change, the oil level scale being carved with outer cover under different temperatures.When oily total amount is constant, oil level can indicate
In current environmental temperature value, when oil mass increases and decreases, it can make expander that harmomegathus change highly occur, oil level instruction, which can deviate, works as
Respective change, the change of the distance can also occur for the distance between top on the inside of preceding ambient temperature value, expander top and outer cover
With oil level height direct correlation, therefore, this can be drawn by measuring the distance between top on the inside of expander top and outer cover
The actual oil level change of equipment.
In use, oil level detection sensor and corresponding current transformer can be numbered, a signal receives display
Device can correspond to multiple oil level detection sensors and be operated.
The utility model beneficial effect includes：
With in the prior art directly by way of the oil level glass of current transformer carries out oil level monitoring compared with, use
The utility model carries out oil level monitoring, reduces monitoring difficulty, has saved monitoring cost, improves monitoring efficiency.
