Beschreibung
Zusammenfassung:	The invention discloses a direct current, temperature and pressure monitoring device for electrical equipment. The direct current, temperature and pressure monitoring device comprises a data collecting and processing unit, a digitization output unit and a fiber bragg grating sensing unit. The fiber bragg grating sensing unit, the data collecting and processing unit and the digitization output unit are connected in sequence. The fiber bragg grating sensing unit at least comprises a temperature optical fiber sensing element, a current optical fiber sensing element and a pressure optical fiber sensing element, wherein the temperature optical fiber sensing element, a current optical fiber sensing element and the pressure optical fiber sensing element are used for collecting the temperature, the current and the pressure of a position to be measured of the electrical equipment respectively. The direct current, temperature and pressure monitoring device for the electrical equipment simultaneously monitors three diff
