JSZV18-10_6BR voltage transformer

structural features ：                                                                                                                                                                                             

The transformer is one of import electrical appliances in electric system. It’s similar to power transformer and also used to transformer voltage or current in the circuit. However, transforming voltage and current by power transformer aims at transferring electric energy while transforming voltage and current by transformer aims at measuring and monitoring voltage or current in the circuit. Generally, power transformer owns large capacity as well as large change difference of voltage or current. While transformer owns small capacity as well as smaller change difference of voltage or current. In measuring circuit. The transformer that transforms current and supplies electricity for current meter and relay is called current transformer. The transformer that transforms voltage and supplies electricity for voltage meter and relay is called voltage transformer.

There is no gas, steam, chemical sediment, dust or other explosive and corrosive media that seriously affect the transformer.
                                                                                                                                                                                                                                     

No serious vibrations or bumps. anyone.

Precaution：

When the primary current passes through the current transformer, the secondary winding is not allowed to open circuit,
Otherwise, high pressure will be generated, which will affect the performance of the product.

The secondary winding of the voltage transformer is not allowed to be short-circuited. Otherwise it will burn the transformer.

The repeated power frequency withstand voltage test of the primary winding shall be performed at the specified test voltage.
