Abstract

The invention relates to a shockproof dial SF6 gas density relay which comprises a base, a cross beam, at least one regulating lever, the micro switches which are set in pairs with the regulating levers and various operating arms which are installed on various micro switches. The invention is characterized in that the invention also comprises a reinforcing mechanism which reinforces the micro switches, namely, reinforces the housing for the micro switches, or a reinforcing mechanism which limits the operating arm of the micro switches and the regulating levers while the reinforcing mechanism reinforces the housing of the micro switches. The reinforcement mechanism is installed in the housing and comprises at least a reinforcing part which is fixed in the housing of a selected micro switch. The micro switches and the base are installed on both sides of the cross beam and the micro switches are installed on top of the corresponding regulating levers. The invention has completely eliminated the oil leakage problem and needs not fill silicon oil and has the advantage of shock resistance. The invention can be well applied to the SF6 electric devices.

Description

technical field

[0001] The invention relates to a relay, in particular to a relay used in SF 6 (Sulfur hexafluoride) Anti-vibration pointer type SF on electrical equipment 6 Gas density relay. Background technique

[0002] 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.

[0003] SF 6 The arc extinguishing medium and insulating medium of electrical products are SF 6 Gas, no gas leakage can occur. In the event of an air leak, SF cannot be guaranteed 6 Electrical products operate reliably and safely. So monitor SF 6 SF for electrical products 6 The density value is very necessary.

[0004] At present, a mechanical pointer SF is generally used. 6 Gas density relay to monitor SF 6 Density, that is, when SF 6 When an electrical product leaks, the relay can alarm and lock, and at the same time display the on-site density value.

[0005] The density relay ge...
