Title:
OVERCURRENT PROTECTION APPARATUS, AND EXPLOSION-PROOF SOLENOID VALVE ON WHICH OVERCURRENT PROTECTION APPARATUS IS INTEGRATED
Document Type and Number:
WIPO Patent Application WO/2023/134760
Kind Code:
A1
Abstract:
Provided in the present disclosure are an overcurrent protection apparatus for an electromagnetic actuation device, and an explosion-proof solenoid valve on which said overcurrent protection apparatus is integrated. The overcurrent protection apparatus for an electromagnetic actuation device according to the present disclosure comprises: at least one discharge circuit level, which is configured to be connected in parallel between a current input port and a current output port of an electromagnetic actuation device, and is used for releasing overcurrent; at least one limiting circuit level, which is configured to be connected in parallel between the current input port and the current output port, and is used for limiting a voltage between the current input port and the current output port and releasing overcurrent; and at least one attenuation circuit level, which is configured to be connected in series in a current path between the current input port and the current output port of the electromagnetic actuation device, and is used for attenuating overcurrent in the current path, wherein the limiting circuit level is closer to the electromagnetic actuation device than the attenuation circuit level and the discharge circuit level.
