The good price and quality 1500V DC Contactor is generally used to control the on-off of larger currents. Therefore, when the 1500V DC Contactor is suddenly disconnected from the connected state, that is, at the moment when the two moving contacts of the High voltage DC Contactor are separated from the two static contacts, arcs will be generated respectively.
Since the instantaneous temperature of the arc of the good price and quality 1500V DC Contactor can reach more than a thousand degrees Celsius, it is easy to cause damage to the internal parts of the 1500V DC Contactor. The temperature of the 1500V DC Contactor arc can burn out the inner wall of the arc extinguishing chamber, and even the static contact of the 1500V DC Contactor. The head or moving contact head is burnt out, etc., which affects the service life of the DC contactor.
The high voltage 1500V DC Contactor controls the on-off of High voltage DC Contactor, that is to say, the good price and quality 1500V DC Contactor cannot use the AC contactor to avoid the arc phenomenon generated inside it. Therefore, how to reduce the arc in the 1500V DC Contactor It is also a difficult problem that needs to be studied and improved.
