Description
Technical field
Propaganda board field is the utility model is related to, more particularly to a kind of high-voltage DC contactor.
Background technology
Contactor is divided into A.C. contactor (voltage AC) and D.C. contactor (voltage DC), it be applied to electric power, distribution with
Electricity consumption occasion.Contactor broadly refers to flow through current induced magnetic field using coil in industrial electro, makes contact closure, to reach control
Make the electrical equipment of load.In electrotechnics, because fast shut-off exchange and direct current major loop and can be frequently switched on and high current
The device of (reaching 800A) circuit is controlled, also is used as controlling Gong Chang She Bei ﹑ as Kong Dui Xiang ﹐ so often applying to motor
The electrical load such as the hot device ﹑ machine-tools of electricity and various kinds electric power unit, contactor can not only be switched on and off circuit, but also have
Low-voltage release guard acts on.Contactor control capability is big, is automatic control system suitable for frequent operation and far distance controlled
In one of critical elements.At present due to contact resistance be present at contact, during normal work and breaking current, production
Raw localized hyperthermia, after long-term use of, contact surface oxidation.Above-mentioned reason is stepped up the contact resistance between contact, leads
Contact is caused to be unable to good contact, so as to influence contactor service life.
Utility model patent CN201420531217.0 discloses a kind of two-way high-voltage DC contactor in parallel, overcomes biography
System A.C. contactor be used under two-way direct current control condition need drop volume using and can not substance avoid arc-suppression function hidden danger
The drawbacks of, but the problem of service life is not long be present.
