Specific embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of electricity consumption maximum demand automatic monitoring device, by electric current relay KA, time relay KT, in
Between relay KM cooperation measure and control device and protective relaying device composition.The automatic monitoring and control to electricity consumption maximum demand may be implemented
System.Apparatus structure is simple, and low manufacture cost, the period is short, easy to maintain, is not take up additional installation site, and stable and reliable operation is led to
It is strong with property.
Measure and control device is electrically connected with electric current relay KA, electric current relay KA respectively with time relay KT and intermediate relay
Device KM connection, time relay KT is in parallel with intermediate relay KM, and intermediate relay KM is connected with warning device, the time relay
The extraneous power load circuit of KT connection.
Warning device includes electric bell DL and signal lamp: green light HG, red light HR connect with intermediate relay KM, work as electricity consumption
