Abstract

The invention relates to an electromagnetic lock for a manual operation mechanism of a disconnecting switch. The electromagnetic lock comprises a sealing box composed of a base plate and a stainless steel cover and is characterized in that a lock plunger mechanism, a contactor and a manual unlocking mechanism are respectively arranged in the sealing box, wherein the lock plunger mechanism is locked or unlocked by the contactor in order to operate the manual operation mechanism. The contactor has the advantages of long service life, reliable performance and greatly reduces the failure rate; and when the lock plunger mechanism is unlocked without being powered in emergencies, non-power installation and maintenance, the lock plunger mechanism can be unlocked by the manual unlocking mechanism.

Description

technical field [0001] The invention relates to an electromagnetic lock for an isolating switch operating mechanism, in particular to an electromagnetic lock for an isolating switch operating mechanism which is safe and reliable and can be manually unlocked under emergency and no-electricity installation conditions. Background technique [0002] The manual operating mechanism of the isolating switch is used to manually open and close the isolating switch knife switch. In order to prevent human misoperation, an electromagnetic lock for locking is usually set on the manual operating mechanism. The general electromagnetic lock with manual operating mechanism includes a locking mechanism for locking the operating mechanism and an electromagnetic device for controlling the locking mechanism. Poor, the internal parts are easily corroded, causing the lock bolt to fail to move, which affects the use, and must be powered on to unlock, and cannot be moved during emergency, no-power in...
