Abstract

The invention discloses a gas density relay with a simulation verification function and a simulation verification method thereof. The gas density relay comprises a gas density relay body, a simulationreference signal unit, a simulation verification signal unit, a driving contact action mechanism and an intelligent control unit. The intelligent control unit is used for acquiring a current workingstate of a monitoring part according to verification of a simulation verification signal generated by the simulation reference signal unit to the simulation verification signal unit so that precisionof the gas density relay can be quantitatively and accurately monitored; and the driving contact actuating mechanism is arranged so that the gas density relay body gives an alarm and / or locks the contact action, and the contact actuating mechanism and the contact of the gas density relay body are normal. The gas density relay and the method are used for monitoring the gas density of gas-insulatedor arc-extinguished electrical equipment and completing online simulation or virtual verification of the gas density relay at the same time, working efficiency is improved, operation and maintenance cost is reduced, and safe operation of a power grid is guaranteed.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a gas density relay with a simulation verification function applied to high-voltage and medium-voltage electrical equipment and a simulation verification method thereof. Background technique [0002] At present, SF6 (sulfur hexafluoride) electrical equipment has been widely used in the power sector and industrial and mining enterprises, which has promoted the rapid development of the power industry. In recent years, with the rapid economic development, the capacity of my country's power system has expanded rapidly, and the amount of SF6 electrical equipment has increased. The role of SF6 gas in high-voltage electrical equipment is arc extinguishing and insulation. If the density of SF6 gas in high-voltage electrical equipment decreases and the micro-water content exceeds the standard, it will seriously affect the safe operation of SF6 high-voltage electrical equipment: th...
