Description
Technical Field
The utility model relates to a three-phase alternating current motor technical field especially relates to a connector lug protection type three-phase alternating current motor.
Background
In the three-phase alternating current motor, a copper wire motor and an aluminum wire motor are arranged according to different materials of wire ends. In the production of three-phase alternating current motor companies adopting aluminum wire connectors, the connection of the wire ends basically adopts a terminal crimping process, so that the efficiency is high, and the connection is firm. For high-power motor wiring, in a terminal crimping process, when a plurality of strands of electromagnetic wires are connected together, an insulating layer of insulating paint of the electromagnetic wires needs to be removed by a paint remover, and then the electromagnetic wires are crimped together; when in compression joint, a section of length of the aluminum wire which is removed from the insulating protective layer is inevitably exposed outside the terminal, and after the section of aluminum wire copper wire joint or the aluminum wire joint which is exposed in the air meets water molecules in the air, the aluminum electromagnetic wire can be oxidized or electrochemically corroded; the resistance of the aluminum wire joint is increased, the actual wire diameter is thinned and gradually oxidized and disconnected; the service life of the electric appliances such as the motor is influenced, the motor is scrapped in advance, and the resource waste is caused.
At present, hot melt adhesive sealing joints, thermosetting adhesive sealing joints, hot shrinkage tube protection with adhesive and tin welding and casing protection are commonly used. The former two have the defects of high cost, environmental pollution and energy waste, and the latter protection is not thorough, so that the aluminum wire is easily oxidized, and the service life of the used electric appliance is further influenced.
At present, an insulating sleeve is adopted for a copper-aluminum wire (aluminum-aluminum wire) joint, no extra protective measures are taken at the joint, and in a paint dipping process of a motor, insulating paint is diluted and has low concentration; the joint can not well cover and protect the exposed aluminum wire and the joint by insulating paint due to the adoption of a section of sealing insulating cap.
The copper-aluminum wire (aluminum-aluminum wire) joint with the adhesive insulating sleeve is adopted, the joint is protected by the adhesive insulating sleeve, only the joint is partially protected, the joint cannot be completely protected, and the aluminum wire can be contacted with air and oxidized.
A copper-aluminum wire (aluminum-aluminum wire) joint of a hot melt adhesive and an insulating sleeve is adopted, the joint is protected by a hot melt adhesive, and then the insulating sleeve is sleeved for thermal shrinkage. Although the joint can be protected, the process is complicated and the cost is increased; energy is wasted because the heating is always needed during working; volatile matters generated by heating the hot melt adhesive pollute the environment and affect the health of people; manual operation is easy to cause untight sealing and cannot play a role.
The joint of the copper-aluminum wire (aluminum-aluminum wire) adopting thermosetting glue is protected by thermosetting glue and then sheathed with an insulating sleeve for thermal shrinkage. Although the joint can be protected, the process is complicated and the cost is increased; the thermosetting adhesive is easy to cure during working, so that waste is easily caused; in addition, volatile matters generated by the thermosetting adhesive pollute the environment and human bodies and affect the health of the human bodies.
