Abstract

The invention relates to a comprehensive electric energy detector for direct-current power supplies. The detector comprises a measuring host for measuring electric energy, a remote signaling host for detecting the states of fuse wires, and a display and communication host, wherein the measuring host and the remote signaling host are connected with the display and communication host by communication cables; the measuring host samples voltage and current values on an input loop and an output loop and calculates power and electric energy data; the remote signaling host detects the states (whether broken or not) of the fuse wires on the input loop and the output loop; and the display and communication host reads various parameter values acquired by the measuring host and the states of the fuse wires acquired by the remote signaling host through the communication cables, correspondingly displays the data and triggers alarms. The comprehensive electric energy detector for the direct-current power supplies can display voltage, current, power and electric energy parameters, has rich alarm types, can realize the alarms for a plurality of electricity utilization situations such as overvoltage and undervoltage alarms, a current early alarm, the alarms for the upper and lower limits of the current, a fuse wire breakage alarm and the like, and meets requirements on internet data center (IDC) machine room power supply management.

Description

technical field [0001] The invention relates to an electric energy detection device, in particular to a DC power supply comprehensive electric energy detector capable of measuring multi-circuit voltage, current, power and electric energy and having multiple types of alarm functions. Background technique [0002] The IDC computer room (Internet Data Center, Internet Data Center) mainly provides server hosting, firewall and other services, and mainly serves the server hosting of various websites, ISP / ICP, SP / CP, and the power supply is the heart of these communication networks, and is the core of the entire communication network. The source of power for the safe and reliable operation of the Internet. [0003] The existing DC power distribution cabinet in the IDC machine room can be equipped with working voltage and current parameter display, with overvoltage and undervoltage alarm functions, and can set and control alarm bells, etc., but lacks the display of parameters such ...
