Embodiment Construction

[0015] Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of anti-vibration device of switch pendulum for sulfur hexafluoride gas density relay, comprises push rod 5, switch pendulum 2, one end of expansion tube 6 is connected on fixing base 3, the other end Connected to the connecting seat 1, a section of the ejector rod 5 is threaded, locked and installed on the connecting seat 1 through the nut 11, the switch swing rod 2 is installed on the micro switch 4 to drive the micro switch 4, and the micro switch 4 is installed on the mount 3. There is a groove 9 at the head of the push rod 5, and there is a long hole 7 on the switch swing rod 2. move, so that the head of the ejector rod and the switch swing rod can also be realized; a better embodiment is that there are cylindrical bosses 8 at both ends of the groove 9, and the cylindrical bosses 8 at the head of the ejector rod 5 are clamped Hold the switch swing rod 2 with the long hole 7; in this way, the displacement of the expans...

Abstract

This invention relates to a switch shockproof device used in an oil-free shockproof expansion tube sulfur fluoride gas density relay including a mandril and a switch sway bar, in which, one end of the expansion tube is connected on a fixed frame, the other end is connected on a connection base, the mandril is mounted on the connection base, the switch sway bar is installed on a microswitch set on the fixed base to drive it characterizing that the head of the mandril is opened with a groove, a long hole is set on the switch sway bar, the groove is inserted into the long hole to move along it to drive the sway bar.

Description

(1) Technical field [0001] The invention relates to a sulfur hexafluoride gas density relay, in particular to an oil-free anti-vibration expansion tube type sulfur hexafluoride gas density relay switch anti-vibration device. (2) Background technology [0002] The existing switch pendulum for expansion tube type sulfur hexafluoride gas density relay is directly driven by the ejector rod, one end of the expansion tube is fixedly connected to the fixed seat, the other end is connected to the connecting seat, and the ejector rod is installed on the connecting seat , the switch swing rod is installed on the micro switch to drive the micro switch, the micro switch is fixed on the fixed seat, the head of the ejector rod corresponds to the switch swing rod, and there is no direct constraint between the two. When encountering vibration, the displacement and separation between the push rod and the switch swing rod are likely to occur, causing the relay to fail and cause an accident. ...
