[0002] The substation situation awareness analyzer adopts an aluminum alloy portable integrated box design with good mechanical properties and corrosion resistance. The whole machine is light in weight and the terminal can be placed in the host box, which is very suitable for on-site carrying and use. Both the terminal and the host use large-screen dot matrix LCD displays, all displayed in simplified Chinese, intuitive operation and with background lights, convenient for use in dark places, the terminal and the host are flexibly configured, there is no binding relationship, and no reset is required during configuration. The host number can be flexibly changed through the keyboard, thereby realizing user identification of multiple distribution transformer power supply areas under complex conditions. The host has a real power supply anti-misconnection protection function, and the substation identification instrument will quickly and automatically cut off the circuit to protect the safety of the instrument and the operator. The terminal has a countdown prompt function and sound prompts when waiting.

[0003] The existing portable substation situation awareness analyzer adopts a combined assembly structure of two main housings. When the interface on the shell structure moves after the plug-in, it causes difficulties in installation and construction, which directly affects most of the meter box main switches that are directly connected to the cable branch box or the distribution room outlet switch, resulting in power quality problems. There is voltage instability in the low-voltage substation, and high and low voltage periods occur. The power plug of the substation situation awareness analyzer is easy to fold and break when used portablely. There is voltage instability in the low-voltage substation, and high and low voltage periods occur, three-phase imbalance, high loss, harmonic problems, etc. Utility Model Content
