The utility model discloses an asymmetric cooperative control three-phase balance motor soft starter, comprising a three-phase AC power supply input end, a power adjusting unit, an output end connected to a three-phase asynchronous motor, and a main controller which are connected in sequence. The power adjusting unit comprises an A-phase control module which is internally provided with a first thyristor at least controlled by a main controller; the B-phase control module is internally provided with a pair of antiparallel second thyristors controlled by the main controller; and the C-phase control module is internally provided with a pair of third thyristors which are controlled by the main controller and are reversely connected in parallel. The main controller cooperatively controls the conduction angles of the first thyristor, the second thyristor pair and the third thyristor pair in the starting process of the motor by outputting a control signal so as to adjust the voltage applied to the motor and improve the balance of the three-phase output voltage. According to the utility model, the three phases are controlled, so that the three-phase balance during starting is effectively improved, and the vibration and noise of the motor are reduced.

The invention provides a split type electromagnetic voltage regulation soft starting cabinet, and relates to the field of motor soft starters. The split type electromagnetic voltage regulation soft start cabinet comprises an inner structural beam, an outer water curtain cabinet and a liquid reactor assembly, the liquid reactor assembly is installed in the inner structural beam and comprises a sealed cabinet body, an inner structural frame and a reactor, the reactor is installed in the inner structural frame, the inner structural frame is installed in the sealed cabinet body, and the outer water curtain cabinet is installed in the sealed cabinet body. Cooling oil is arranged in the sealed cabinet body, and the reactor is soaked in the cooling oil. According to the split type electromagnetic voltage regulation soft start cabinet, the liquid reactor assembly is arranged, vibration generated when a reactor is started can be filtered by rubber columns and springs, the reactor is soaked in cooling liquid, frequency vibration cannot be completely transmitted outwards, and huge noise cannot be generated during operation; cooling oil of the liquid reactor assembly can be circularly sprayed on the heat dissipation aluminum back plate to form an oil curtain, and a noise isolation layer is formed.

The invention relates to the technical field of motor soft starters, and discloses a motor soft starter which comprises a soft starter body and a mounting plate, mounting strips are slidably connected to the top end and the bottom end of the mounting plate, a limiting mechanism used for adjusting the position of the mounting plate is arranged between the mounting strips and the mounting plate, and a supporting plate is mounted on the front face of the mounting plate. The soft starter comprises a soft starter body, a supporting plate is arranged on the soft starter body, a dismounting mechanism used for mounting the soft starter body is arranged on the supporting plate, the soft starter body is sleeved with a protective cover, and a connecting mechanism is arranged between the protective cover and the soft starter body. The position of the soft starter can be conveniently and directly adjusted by a worker, so that the worker can conveniently connect a wire to the soft starter according to an installation environment, the worker does not need to disassemble and assemble the soft starter again, and the flexibility of the soft starter during installation and use is greatly improved.
