Abstract

The invention provides an LCI valve group device, and belongs to the technical field of motor starting. In order to solve the problems of large occupied space, high cost, heavy weight, poor ventilation and heat dissipation effects and the like of an existing auxiliary device for variable-frequency soft start of a middle-high voltage synchronous motor, the invention further provides the LCI valve group device. The device comprises an insulating shell, a disc spring device, a cooling fin group, a capacitor, a metal cabinet body assembly and a trigger plate. The LCI valve group device is small and exquisite in boundary dimension, more convenient to transport, low in production cost, more convenient to install and debug on site, good in heat dissipation and ventilation effect when the whole cabinet body operates, diversified in power utilization installation grade of the cabinet body and capable of better adapting to the installation environment on site.

Description

technical field [0001] The invention belongs to the technical field of motor starting, and in particular relates to an auxiliary device for variable frequency soft starting of a medium-high voltage synchronous motor, in particular to an LCI valve group device. Background technique [0002] With the increase of the country's investment in industrial development and the rapid development of industry, electrical equipment is being updated day by day. The existing cabinet type medium and high voltage synchronous motor frequency conversion soft start device has the following characteristics: large floor area, heavy cabinet weight, and high cost , Poor ventilation and cooling effect. [0003] Therefore, in order to adapt to market demand and product upgrading, it is necessary to do: whether the cabinet-type medium and high-voltage synchronous motor frequency conversion soft start device, especially the LCI valve group device, is small in size, whether it is convenient to transport...
