Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of contactors, in particular to a high-current battery short-circuit test contactor. Background Art
[0002] Contactor is a widely used switch electrical appliance. It uses electromagnetic, pneumatic or hydraulic principles to realize the on and off of the main circuit through the control circuit. Contactor has the advantages of strong current breaking capacity, rapid action, safe operation, frequent operation and remote control, but it cannot cut off the short-circuit current. Therefore, contactor usually needs to be used in conjunction with fuse. The main control object of contactor is motor, and it can also control other power loads, such as welding machine, electric furnace, etc.
[0003] During the use of the existing contactor, when the contactor coil is energized, the coil current will generate a magnetic field. The generated magnetic field causes the static iron core to generate electromagnetic attraction to attract the moving iron core, and drive the AC contactor point to move, the normally closed contact is disconnected, and the normally open contact is closed. The two are linked. When the coil is de-energized, the electromagnetic attraction disappears, and the armature is released under the action of the release spring, so that the contacts are restored, the normally open contact is disconnected, and the normally closed contact is closed. Since the connecting wires cannot be fixed, they are affected by external factors during use. For example, when the staff is checking the connecting wires, they may accidentally touch other connecting wires due to combing the connecting wires, which may cause the other connecting wires to fall off. At the same time, the connection points of the connecting wires cannot be effectively dustproof, and the floating dust in the air can easily enter the contacts of the adsorption connection. Over time, the sensitivity of the contacts is affected, which brings trouble to the staff. For this reason, we propose a high-current battery short-circuit test contactor. Utility Model Content
