The invention relates to a series-parallel circuit switching device, which comprises a series starting switch S1, a C relay with a normally-open switch, M-1 KB relays with a normally-closed switch and a KHM relay with a normally-closed switch, M-1 KH relays with a normally-open switch and a normally-closed switch, and M-2 series-parallel number selection switches, and is characterized in that coils of all of the relays are in parallel connection, the relay coils are connected in parallel and are then connected with two ends of a power supply through connecting the series starting switch S1 in series; the normally-open switches and the normally-closed switches of the relays form a logic parallel circuit, complete series connection can be realized as long as the starting switch S1 is closed, and the required circuit group number is realized through the series-parallel number selection switches. The device provided by the invention realizes non-dismounting type switching of series-parallel circuits, and is convenient and efficient. The specification of the series-parallel circuit switching device can be determined according to the maximum number M of components required to be switched, and the switchable number of components ranges from 2 to M, thereby enabling the device to have more use values.
Description
technical field [0001] The invention relates to a conversion circuit, in particular to a series-parallel circuit conversion device. Background technique [0002] Series and parallel circuits are widely used in daily life and industrial production. However, some equipment and components may need to use two different connection methods in series and parallel during use. When the number of equipment is small and the working environment is suitable , It is acceptable to manually convert the series-parallel circuit, but for the large quantity, high conversion frequency, and harsh working environment, it is no longer suitable for manual conversion. The series-parallel circuit conversion is mostly used in lead-acid battery packs. Because of its cheap price, simple production process, and high-current discharge capability, lead-acid batteries are used as energy storage devices and Backup power is used on a large scale. However, due to the limited voltage and capacity of a single b...
