The invention discloses a simple system for monitoring the operation state of power equipment. The system comprises a data acquisition module, a central processing module, a storage module and a display module, wherein the data acquisition module acquires voltage and current during the operation of power equipment and the temperature of the equipment and transmits the voltage and current and the temperature to the central processing module; the central processing module calculates a voltage effective value, a current effective value, active power, reactive power and apparent power according tothe received voltage and current measurement values; a voltage measurement value, a current measurement value, a temperature measurement value and a calculation result of the central processing unitare stored in the storage module; and the display module is connected with the central processing module and the storage module and can display corresponding data according to user requirements. By using the system provided by the invention, the operation state of the power equipment can be monitored and recorded in real time, so that accidents can be judged and prevented through real-time monitoring data, or reasons of the accidents can be analyzed by calling historical data after the accidents occur.
Description
technical field [0001] The invention relates to the technical field of electric equipment safety, in particular to a simple system for monitoring the operating state of electric equipment. Background technique [0002] Power equipment such as transformers, condensers, reactors, circuit breakers, and switches are commonly used in industry and are important power equipment for stable power supply and product production. Power equipment may cause failures, explosions, fires and other safety accidents due to various factors such as neglect of maintenance, equipment failure, overvoltage, overload, etc., which will lead to interruption of product production and economic losses. In order to reduce this kind of damage, it is necessary to confirm the operating status of the power equipment and the state of the power equipment by regularly detecting, storing, recording and analyzing the voltage, current, temperature, etc. of the power equipment, so as to prevent accidents. In additio...
