Description
Technical field
The utility model relates to a kind of contactor, particularly a kind of two-way high-voltage DC contactor in parallel.
Background technology
The contactor of automobile refers to and utilizes coil to flow through current induced magnetic field, makes contact closure, realizes effective transmission of power.Conventional contactor is by electromagnetic system (dynamic unshakable in one's determination, fixed core, solenoid), contact system and arc-control device composition.After the solenoid energising of contactor, very strong magnetic field can be produced, make fixed core produce electromagnetic attraction and attract dynamic unshakable in one's determination, and drive contact action: contact closure; When the coil is de-energized, electromagnetic attraction disappears, and dynamic iron core discharges under the effect of retracting spring, and contact is restored: contact disconnects.
Contact can produce electric arc in make and break process, the high temperature that electric arc produces can make contact burn black, burn, singe and produce metallic particles, directly affect the useful life of contactor.General high-voltage DC contactor is commonly used to new energy motor, the field such as inverter, charging/discharging apparatus, direct current can reach 200A or higher, and voltage is then between 500V-900V, when voltage is more and more higher, the problem of electric arc also becomes more and more serious.Solving one of method of electric arc is the magnetic quenching adopting sealing means, the magnetic field that usual two magnetic conductive boards (permanent magnet) produce is vertical with the line direction of two contacts, adopt sealing technology be isolated from the outside by arc control device and be filled with insulation arc extinguishing gases, to reach good arc quenching effect simultaneously.
Current direct current two-way contactor, generally can get two groups with three of an A.C. contactor group interchange contact and use as direct current, need derate to use, and there is potential faults because arc quenching principle is different.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of two-way high-voltage DC contactor in parallel, solves the problems referred to above, facilitates wiring and installation.
The technical scheme in the invention for solving the above technical problem is:
A kind of two-way high-voltage DC contactor in parallel, comprise 2 groups of contactors, control line and shell, is characterized in that: described shell is divided into two cavitys cut off, and each inside cavity can put into 1 group of contactor; Shell is drilled with the circular hole can deriving control line.
Described outer casing bottom has fixing hole, and fixing hole and base are 45° angle, and two adjacent fixing holes are symmetrical along axis.
Described contactor comprises stem, fixed contact, moving contact, iron core, moving axis and return spring.Iron core is fixed on moving axis lower end, and return spring is fixed in the middle part of moving axis, and moving contact is arranged on moving axis top; Stem and fixed contact are fixed into an entirety, are in directly over moving contact, two fixed contacts corresponding two moving contact contacts respectively.
Described circular hole is positioned at the same side place on face length limit, shell upper end.
The technique effect of the utility model employing achieved by technique scheme is:
The utility model overcomes to need derate to use and the drawback substantive cannot avoiding arc-suppression function hidden danger under conventional AC contactor is used in two-way direct current controlled condition, the function that one group of control line controls the break-make of two groups of main contacts simultaneously can be met, and be packaged into a two-way high-voltage DC contactor, facilitate wiring and installation.
