Description
Technical field
The utility model relates to contactor, particularly relates to D.C. contactor.
Background technology
D.C. contactor is the important control element in the electric transmission control system of oil-well rig and offshore drilling platforms.The most build of this series products used was large in the past, and outward appearance is coarse, anti-vibration ability, and performance is stable not.Along with industrial development, production environment and production equipment environment for use are greatly improved, and are badly in need of a kind of type little, and capacity is large, and stable performance, the new science and technology product that fail safe is good adapts to market demand.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rotation-type DC contact.
For solving the problems of the technologies described above, the technical solution of the utility model is: comprise contact system, electromagnetic system, arc quenching system and auxiliary contact system, described contact system is main, arcing contact compound connection structure, main contact is made up of moving contact and fixed contact, fixed contact is connected with quiet junction block, and arcing contact is made up of moving arcing contact and static arc contact; Described electromagnetic system comprises electromagnetic attraction coil, yoke, iron core and armature; Described arc quenching system contains arc-extinguish chamber, arc control device and electromagnetism blow-out coil; Described yoke is made U-shaped by electrical pure iron plate, and described electromagnetic attraction coil, iron core are arranged in described U-shaped yoke by screw.
Described fixed contact is provided with groove, and the cramp in described arc-extinguish chamber is buckled on this groove, and the Flexible Connector simultaneously in described arc-extinguish chamber and support interlock, and this arc-extinguish chamber is fixed.
The beneficial effects of the utility model are, described yoke is made U-shaped by electrical pure iron plate, electromagnetic attraction coil, iron core are arranged in U-shaped yoke by screw, electromagnetic attraction coil and iron core can be installed from yoke separately, directly, dismounting, do not need to install, dismantle other parts, keep in repair very convenient; Cramp in arc-extinguish chamber is buckled on groove, and the Flexible Connector simultaneously in arc-extinguish chamber and support interlock, and arc-extinguish chamber is fixed, owing to not adopting screw to connect, structure is simplified more compact, volume reduces, install simultaneously, dismantle, safeguard convenient, improve Total Product performance.

Accompanying drawing is the structural representation of rotation-type DC contact.
In figure: 1-arc-extinguish chamber; 2-arc control device; 3-Flexible Connector; 4-reaction spring; 5-auxiliary contact; 6-support; 7-armature; 8-iron core; 9-electromagnetic attraction coil; 10-moves junction block; 11-yoke; 12-base; The quiet junction block of 13-; 14-cramp; 15-fixed contact; 16-electromagnetism blow-out coil; 17-static arc contact; 18-moving contact; 19-contact supporter; 20-moving arcing contact.
Embodiment
As shown in drawings, this rotation-type DC contact comprises contact system, electromagnetic system, arc quenching system and auxiliary contact system, contact system is main, arcing contact compound connection structure, main contact is made up of moving contact 18 and fixed contact 15, fixed contact 15 is connected with quiet junction block 13, and arcing contact is made up of moving arcing contact 20 and static arc contact 17; Electromagnetic system comprises electromagnetic attraction coil 9, yoke 11, iron core 8 and armature 7, and yoke 11 is made U-shaped by electrical pure iron plate, and electromagnetic attraction coil 9, iron core 8 are arranged in U-shaped yoke 11 by screw; Arc quenching system contains arc-extinguish chamber 1, arc control device 2 and electromagnetism blow-out coil 16, electromagnetism blow-out coil 16 is in parallel with major loop, and fixed contact 15 is provided with groove, and the cramp 14 in arc-extinguish chamber 1 is buckled on this groove, Flexible Connector 3 simultaneously in arc-extinguish chamber 1 interlocks with support 6, and arc-extinguish chamber 1 is fixed; Auxiliary contact 5 is assembled in above support 6.
Operation principle: after electromagnetic attraction coil 9 is powered, electromagnetic system sets up electromagnetic field, iron core 8 pairs of armature 7 produce suction, armature 7 moves downward, drive moving arcing contact 20, moving contact 18 move downward, moving arcing contact 20 first contacts with static arc contact 17, and moving contact 18 contacts with after fixed contact 15, and D.C. contactor major loop closes.During 9 power-off of electromagnetic attraction coil, the electromagnetic field that electromagnetic system is set up disappears, iron core 8 pairs of armature 7 lose suction, under the effect of reaction spring 4, armature 8 moves upward, and drive moving arcing contact 20, moving contact 18 move upward, and moving contact 18 is first separated with fixed contact 15, moving arcing contact 20 is separated with after static arc contact 17, and D.C. contactor major loop disconnects.
The utility model is a kind of light task Special contactor, is applicable to the load scenarios of no-load deciliter character, also can be used for transshipping in right amount in short-term the control of DC motor or the joint weldment of other DC circuit, but be not suitable for the electric current under disjunction malfunction.
Because product structure is simply compact, current capacity is large and volume is little, easy for installation, stable performance, and has very high mechanical endurance and excellent anti-seismic performance, is the preferred product of oil-well rig and offshore drilling platforms.
