Abstract
The utility model discloses an electromagnetic lock of a high and low voltage switch cabinet, which comprises a door lock with a lock bar and two to three mutual inductors, wherein one side of the mutual inductors is provided with three terminals for being respectively and correspondingly connected with a three-phase high-voltage leading-in busbar. The electromagnetic lock is characterized in that three leading-out terminals of loops on two sides of the mutual inductors are respectively and correspondingly connected with one connecting terminal of one or three electromagnets in the door lock, the other terminals of the electromagnets are connected with the null lines of the loops on the two sides, and when the electromagnets are electrified, the cores of the electromagnets and the lock bar in a locking state form one or three interlocking mechanisms for locking the lock bar. According to the utility model, the two sides of the mutual inductors of the switch cabinet are utilized for providing power for the electromagnetic lock so as to lock the switch cabinet door, and the cabinet door of the high and low voltage switch cabinet cannot be opened so long as the high-voltage power supply is electrified, so that casualties caused by entering an electrification chamber or touching an electrified body accidently are avoided.
Description
Technical field
The utility model relates to a kind of lockset, and more particularly, it relates to a kind of electromagnetic lock of high and low voltage switch cabinet.
Background technology
