Embodiment 1

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] figure 1 It is a partial cross-sectional schematic diagram of a high-vibration-resistant gas density relay according to Embodiment 1 of the present invention, as figure 1 As shown, the high-vibration-resistant gas density relay of Embodiment 1 of the present invention includes: a sealed air chamber surrounded by a housing 10, a watch...

Embodiment 2

[0050] figure 2 It is a partial cross-sectional schematic diagram of the high anti-vibration gas density relay of the second embodiment of the present invention, as figure 2 As shown, the main difference between the high anti-vibration gas density relay of the second embodiment of the present invention and the first embodiment is that the joint 2 is fixed at the eccentric position of the chassis 8, and the base 16 is sealed and fixed on the transition piece 11, and the transition piece 11 Sealed and fixed on the chassis 8, the chassis 8 is provided with a vent 41, and the joint 2 is sealed on the chassis 8 corresponding to the vent 41. The base 16, the transition piece 11, the bellows 9 and the joint 2 are shown to communicate with each other, so that the density relay communicates with the electrical equipment on the gas path.

[0051] In the high anti-vibration gas density relay of the present invention, the sealing gas chamber is filled with compensation gas, or the bel...

Abstract

The invention discloses a highly-shake-resisting gas density relay. The highly-shake-resisting gas density relay comprises a sealed gas chamber, a signal mechanism and an indicating value display mechanism. The signal mechanism and the indicating value display mechanism are located in the sealed gas chamber. The signal mechanism comprises a corrugated tube and a microswitch. The microswitch is controlled to be turned on or off by the corrugated tube. The indicating value display mechanism comprises a display terminal base, a display bourdon tube, a core, a pointer and a dial. One end of the display bourdon tube is connected with the display terminal base. The core, driven by the display bourdon tube of the indicating value display mechanism, is mounted on a base plate. The pointer is located on the core. The highly-shake-resisting gas density relay has the advantages that compensation gases are arranged in the sealed gas chamber and play a role in temperature compensation and shake resistance, the accuracy of the gas density relay is improved, and production cost and product weight are reduced.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a high anti-vibration gas density relay, in particular to an absolute pressure high anti-vibration gas density relay. Background technique [0002] Electrical products have been widely used in the power sector, industrial and mining enterprises, and promoted the rapid development of the power industry. The arc extinguishing medium and insulating medium of electrical products are gases, which are prone to gas leakage. After gas leakage, the reliable and safe operation of electrical products cannot be guaranteed. Therefore, how to ensure the reliable and safe operation of electrical products has become one of the important tasks of the power sector . [0003] At present, the signal mechanism (signal control part) of the sulfur hexafluoride gas density relay used to monitor the density of sulfur hexafluoride gas in medium-voltage sulfur hexafluoride electrical equipment gen...
