It is mainly used in the bypass circulation filtering system of OLTC. It can timely filter oil while the transformer operates normally, or it can automatically filter the oil after switching of the OLTC. The equipment can efficiently discord the impurities like dissociated carbon, water and oxides in the filtering cycles to ensure the quality of oil, thus it can guarantee the oil insulation, increasing the switching times, postponing the repairing period, decreasing the power cut off times, assuring the voltage quantity and improving the safety and reliability of the OLTC.
BYL is usually installed near the OLTC permanently (the hanging installation or fixed installation beside). There are many kinds of flow rate and accessories with different functions choosed.
Standard control box
Remote control system: Filter element display of machine operation
Positive and negative direction control of the motor, protection of over-load of motor start and phase-lacking.
Humidity relay, 50%-100% adjustable.
Automatically run the filter equipment once after the operation of OLTC, start up the operation time can be set according to requirement from 0-99 hours, but it is usually set with 30 minutes. Another way is to filter every day at the fixed time lasting two hours. The two methods can be chosen accordingly.
