The action principle of the DC contactor is similar to that of the AC contactor, but the magnetic field energy stored by the inductive load is released instantaneously when the DC is disconnected, and a high-energy arc is generated at the breaking point. Therefore, the DC contactor is required to have a certain arc extinguishing function. Medium/large-capacity DC contactors often adopt a single-break point planar layout overall structure, which is characterized by a long arc distance during breaking, and the arc extinguishing cover contains an arc extinguishing grid. The small-capacity DC contactor adopts a three-dimensional arrangement structure with double break points. Pay attention to the following points when choosing a contactor. 1. The rated voltage of the main contact ≥ the rated voltage of the load. 2. The rated current of the main contact is ≥1.3 times the rated current of the load. 3. The rated voltage of the coil. When the circuit is simple and uses less electrical appliances, you can choose 220V or 380V; when the circuit is complex, use more electrical appliances or where it is not safe, you can choose 36V, 110V or 127V. 4. The number and type of contacts of the contactor should meet the requirements of the control circuit. 5. Operating frequency (number of contacts on and off per hour). When the on-off current is large and the on-off frequency exceeds the specified value, the contactor model with the rated current one level higher should be selected. Otherwise, the contacts will be severely heated, or even welded together, causing the motor and other loads to run without phase.inverter reference on | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
