Shakeproof type sulfur hexafluoride gas density relay

Abstract

This invention discloses one anti-vibartion sulfur hexafluoride gas intensity relay, which comprises the following structure: the control part and display part are designed separately; the control part comprises c shape tube, temperature compensation slice, beam, the display part comprises c shape tube, temperature compensation slice, beam and two c shape tubes on the basic socket with other end connected to compensation slice and with other end connected to beam.

Description

technical field [0001] The invention relates to a relay, more specifically to an anti-vibration sulfur hexafluoride gas density relay, which is used in sulfur hexafluoride electrical equipment. Background technique [0002] Sulfur hexafluoride (SF 6 ) Electrical products have been widely used in the power sector, industrial and mining enterprises, and promoted the rapid development of the power industry. Guaranteed SF 6 The reliable and safe operation of electrical products has become one of the important tasks of the power sector. SF 6 The arc extinguishing medium and insulating medium of electrical products are SF 6 Gas, no air leakage can occur, if there is an air leakage, the SF cannot be guaranteed 6 Electrical products operate reliably and safely. So monitor SF 6 Sulfur hexafluoride gas density value for electrical products is very necessary. Traditionally used to monitor the gas density of sulfur hexafluoride, a mechanical pointer density relay is generally us...

Problems solved by technology

However, the control part and the display part of the relay of this structure share a C-type tube 6 and a temperature compensation sheet 7, and the display part and the control part restrict and influence each other when working and selecting parameters. In places where the temperature is high, in order to protect the micro switch and the crossbar from being crushed and deformed, and to maintain reliable operation of the entire system, it is necessary to limit the C-shaped tube 6 to a certain range, and the display accuracy is limited and cannot be achieved. -0.1~0.9Mpa, in addition, the resistance of the micro switch in the control part will also affect the display value of the display part, so the micro switch with strong action force cannot be selected, which limits the further improvement of the anti-vibration performance of the relay; because the display part The structure is not separated from the control part, and the vibration of the pointer of the display part affects the action of the micro switch 91 of the control part; in addition, the temperature compensation sheet 7 cannot account for the difference between the density of the display part and the contact action value of the control part To choose the most suitable temperature compensation sheet
