Abstract

The invention discloses a gas relay leakproofness detection device. The gas relay leakproofness detection device comprises a detection platform, a support is mounted on the detection platform, a clamping component for clamping a to-be-detected gas relay is mounted on the support, an oil filling component is mounted on the detection platform, connected with an oil filling port of the gas relay and used for filling the gas relay with oil and pressurizing the gas relay for leakproofness detection. The gas relay leakproofness detection device has the advantages of simple structure, small size, simplicity in operation and high detection efficiency.

Description

Technical field [0001] The present invention mainly relates to the technical field of power equipment measurement, in particular to a detection device for the tightness of a gas relay. Background technique [0002] The current method of verifying the airtightness of the Buchholz relay and the light gas setting is to use the Buchholz relay calibration platform, which has a large volume and weight and is only suitable for calibration in a laboratory. Although there are also portable Buchholz relays on the market, some of the devices are still too bulky, have motors, and are heavy. Some devices can only verify a certain type of Buchholz relay, which is not very applicable. During on-site maintenance, there may be time constraints or emergency troubleshooting, and the calibration of the Buchholz relay needs to be completed as soon as possible. Therefore, there is an urgent need for devices that can be used on-site for the maintenance team to improve the efficiency of maintenance. Su...
