The invention discloses a medium-voltage switchgear state monitoring device, comprising a single-chip microcomputer, a frequency detection component, a voltage detection component, a current detection component, a first signal conditioning component, a temperature sensor, a second signal conditioning component, a display alarm component, and a keyboard component and a power supply part, the single-chip microcomputer is connected with a frequency detection part, a display alarm part, a keyboard part and a power supply part, the voltage detection part and the current detection part are connected with the frequency detection part, and are connected with the single-chip microcomputer through the first signal conditioning part, so The temperature sensor is connected with the single-chip microcomputer through the second signal conditioning component. The invention realizes the online detection of the important state quantities voltage, current, frequency, power and temperature of the medium-voltage switchgear, and solves the problems of safe isolation from high-voltage electrical appliances and heat exchange with the measured target through infrared temperature measurement. It has the advantages of large temperature measurement range and fast speed.
Description
technical field [0001] The invention relates to a monitoring device, in particular to a state monitoring device for a medium-voltage switchgear. Background technique [0002] In my country's power system, medium-voltage switchgear refers to medium-voltage complete switchgear with a voltage level of 3.6-40.5kV, referred to as medium-voltage switchgear. With the promotion of substation unmanned management mode and comprehensive automation in the power system, the safe operation of switchgear has become particularly important. If the switchgear fails during operation, it will bring extremely serious consequences. First of all, the failure of the switchgear will directly endanger the protected lines and may damage various electrical equipment; secondly, it may cause large-scale power outages and seriously interfere with normal production and living order. [0003] The modern power system puts forward high requirements on the reliability of the safe operation of the switchgear,...
