Description
Technical field
The utility model is related to power equipment monitoring technical field more particularly to a kind of transformer winding pressing force test systems
System.
Background technology
Power transformer is the hinge type key equipment of electric system power transmission and transformation network, is the key that transformation of electrical energy, in electricity
Play an important roll in net, reliability of operation is directly related to the safety and stablization of electric system.Transformer coil passes through
The pressure bowl in nail pressing and winding pressing plate on folder is compressed, pressing force not enough or unbalance stress, the former causes winding to loosen,
Vibration and noise aggravation, and cause nail pressing bowl floating potential discharge or even nail pressing occur after winding is by heavy current impact
Bowl comes off, and the latter causes winding to tilt, and winding deformation occurs after winding is by heavy current impact.
At present, for the test and monitoring of winding pressing force, effective method is there is no, can only be compressed simultaneously by hydraulic test
The pressure values of hydraulic test are converted into the pressing force of winding, there are error, and has a power failure and carries out the recovery or adjustment of pressing force,
It can lead to that power off time is long, and quantities is big, take time and effort consumption wealth.
Utility model content
The utility model provides a kind of transformer winding and compresses force test system, and can solve existing winding pressing force can not
Test and the technical barrier monitored in real time.
In order to achieve the above objectives, the embodiment of the utility model adopts the following technical scheme that：
A kind of transformer winding compresses force test system, it is characterised in that：Including pressure sensor, sensor adapter,
Signal processor and display screen, the pressure sensor, sensor adapter, signal processor and display screen are sequentially connected, institute
It states pressure sensor to be arranged between the nail pressing of transformer winding and pressure bowl, the output signal of the sensor adapter is by described
Signal processor receives and is converted into pressure value, and passes through the display screen and show.
Further, the pressure sensor is column weighting sensor, and cylindrical shape is conducive to reduce point discharge, together
When there is strong shock resistance, the features such as dynamic effect is good.
Further, the signal processor is the DSP or ARM or FPGA processor of integrated A/D converter, has volume
Function small, arithmetic speed is fast.
The beneficial effects of the utility model are：A kind of transformer winding provided by the utility model compresses force test system,
Nail pressing is detected by pressure sensor and the pressure between bowl is pressed to realize the measurement of transformer winding pressing force and monitor in real time,
To improving the manufacturing process of transformer, there is the ageing state for monitoring transformer winding pressing force state and solid insulation promotion to make
With.
