The invention discloses an auxiliary device for verifying a gas relay of a power system, and the device comprises two oil pipe supports, a substrate, and a gas lifting platform. The gas lifting platform is located between the two oil pipe supports. Each oil pipe support comprises a clamping ring, a support rod, and a support pedestal, wherein the clamping ring is connected with the top of the support rod, and the support pedestal is located at the bottom end of the support rod, and two ends of the support pedestal are each provided with a first through hole. The gas lifting platform comprisesa lifting platform pedestal, a lifting mechanism and a gas relay placement platform from the bottom to the top. The lifting platform pedestal is connected with the gas relay placement platform throughthe lifting mechanism, and the four corners of the lifting platform pedestal are each provided with a second through hole. The substrate comprises two pedestals and a sliding rail, and the sliding rail passes through the first through hole and the second through hole. The two pedestals are connected through the sliding rail, and the axis of each clamping ring is parallel to the sliding rail. According to the invention, the device can achieve the coaxial sealing connection of the oil pipes and the gas relay, is simple and convenient in operation, improves the verification efficiency of the gasrelay, and solves a problem of oil leakage caused by a condition that the gas relay is not in coaxial connection.
Description
technical field [0001] The present application relates to the technical field of electric power safety production test, and in particular to a power system gas relay verification auxiliary device. Background technique [0002] In the power system, the gas relay is one of the main protections of the transformer, and the correct action of the gas relay is related to the safety of the transformer operation. According to the relevant regulations such as the power equipment handover acceptance regulations, electrical equipment installation engineering electrical equipment handover test standards, etc., the gas relay needs to be inspected before the transformer is put into operation. [0003] The inspection of the gas relay needs to be set according to the capacity of the transformer it protects. After the setting is completed, it needs to be placed on the gas relay calibration table for calibration. The calibration table is connected to the gas relay through two oil pipes and a ...
