Product description

S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer is also to test a variety of data, S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer measurement data in the process is S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer various physical quantities are constantly tested, in fact, S22-630KVA/35KV/10KV/ The performance of 0.4KV oil-immersed transformer is understood through testing. How much do you know about the common measurement methods and key measurement contents of S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer? Let’s learn more about it with the editor of S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer manufacturers

Power-off measurement: S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer is generally composed of 2 or more sets of coils. In general, the wire diameter of each group of coils is the same, so the advantages and disadvantages can be determined by measuring the DC resistance of each winding. The higher the power, the smaller the resistance, and the smaller the power, the greater the resistance;

If the DC resistance value of the winding is significantly lower than the resistance provided by the manufacturer, it means that the winding has a short circuit or misuse of enameled wire specifications.

Power-on measurement: after power-on, the S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer has no obvious abnormal sound and no obvious increase in surface temperature, and then the AC file of the multimeter is used to detect whether the output voltage of each winding resistance meets the required output no-load voltage, on the contrary, it is judged that the S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer has some shortcomings.

The above are the important methods and key measurement contents of the common S22-630KVA/35KV/10KV/0.4KV oil-immersed transformer for your reference.
