Problems solved by technology

At present, most of the permanent magnet operating mechanisms of foreign brands on the market are not equipped with emergency opening devices. Even those with emergency opening devices use levers for manual opening. Cause damage to circuit devices, and cause serious interference to the measurement and control circuit at the same time, poor safety and reliability

Embodiment Construction

[0012] As shown in the figure, the coils 5 are arranged correspondingly on both sides of the inner cavity of the housing 6, and the magnetic steel 4 is arranged between the two coils 5. The magnetic steel 4 is a continuous ring structure, or a strip-shaped ring structure at intervals. The shaft-connected magnetic core slider 20 connected to the main shaft 1 passes through the center of the coil 5 and the magnetic steel 4 , and the two ends of the main shaft 1 are slidably matched with the end cover 2 and the connecting cover 19 through the oil bearing 7 . The end cover 2 , the connection cover 19 and the housing 6 are fixedly connected by screws 3 . The opening housing 8 is fixedly connected with the connection cover 19 by the screw 3. The opening housing 8 is provided with a rotating thrust magnet 11 and a sliding thrust magnet 17. The rotating thrust magnet 11 and the sliding thrust magnet 17 are respectively composed of two It is composed of semi-circular magnetic steel and...

Abstract

The operating mechanism includes body case, end cover, connection cover, windings on two sides on cavity, steel magnet between windings, magnetic core slider with shaft passing through windings and center of steel magnet forms sliding fit to end cover and connection cover. Manual emergency switch opening device is fixed outside the connection cover. The switch-opening device is composed of shell body, rotational thrust magnet steel and slip thrust magnet steel, which is connected to main shaft fixedly. The disclosed mechanism through emergency switch opening device realizes emergency switch opening by manual operation without electricity supplied. Features are fast speed for opening switch, and good vacuum arc extinguishing performance.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a permanent magnet pulse electric operating mechanism with an emergency opening device. Background technique [0002] At present, the structural design of the electromagnetic drive mechanism of various high-voltage vacuum circuit breakers commonly used in transmission lines, especially high-voltage transmission lines, mostly adopts imported technology from abroad. For example, the existing Su-imitated electromagnetic drive mechanism mainly includes a passage coil, an iron core, a circuit breaker coil, and a ejector connected to the iron core. The ejector is driven by the movement of the iron core, and the ejector controls the mechanical transmission mechanism connected with it. The switch circuit is operated or disconnected by the mechanical transmission mechanism. The mechanical transmission mechanism is composed of a rotating rod, a release rod, a connecting rod, a ...
