LOW-VOLTAGE POWER DISTRIBUTION SYSTEM AND MULTI-FUNCTION INSTRUMENT FOR THE LOW-VOLTAGE POWER DISTRIBUTION SYSTEM

摘要

A low-voltage power distribution system and a multi-function instrument for the low-voltage power distribution system. The multi-function instrument comprises: an instrument body (100); a current collector (10) arranged in the instrument body (100), wherein the current collector (10) is connected to a low-voltage power distribution loop, so as to collect a current of the low-voltage power distribution loop in real time; a register (20) arranged in the instrument body (100), wherein the register (20) is connected to the current collector (10), so as to record the maximum current collected by the current collector (10) in a current scanning period; and a communication unit (30) arranged in the instrument body (100), wherein the communication unit (30) is connected to the register (20), so as to send, after establishing a communication connection with an upper-layer control system (200), the maximum current collected by the current collector (10) in the current scanning period to the upper-layer control system (200). The multi-function instrument can ensure that an upper-layer control system (200) collects, in each scanning period, the maximum current appearing in a low-voltage power distribution loop, so as to facilitate the upper-layer control system (200) in issuing a corresponding control command, thereby ensuring the secure and reliable operation of the power distribution system.
