Abstract
The invention discloses an insulating gas density relay verification method, device and equipment and a storage medium. Real-time contact signal data of all preset contacts are acquired to acquire real-time on-off states of all the preset contacts; increasing the pressure of the insulating gas from the zero-position pressure value to a first target pressure value according to the first pressure change rate; according to the real-time on-off states of all the preset contacts, the preset contacts with the first on-off state switching are determined as working contacts, and first contact pressure values when the working contacts are subjected to the first on-off state switching are obtained; and recovering the pressure of the insulating gas to a zero-position pressure value, and sequentially executing a boosting verification process and a depressurization verification process on the insulating gas density relay by referring to the first contact pressure value of each working contact, so as to complete the verification of the contact pressure value of the insulating gas density relay. Therefore, the automatic scanning of the contact and the self-adaptive verification of the pressure value of the contact are realized, and the verification efficiency is improved.
