Title:
OPENING AND CLOSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/188287
Kind Code:
A1
Abstract:
This opening and closing device opens and closes a space between a first terminal (1a) and a second terminal (1b) that face each other, and comprises a first electrode (2a) provided in the first terminal, and a second electrode (3b) provided in the second terminal and driven to be able to come into contact with and separate from the first electrode. The first electrode and the second electrode come into contact with each other by attractive force between magnets (5a, 5b) disposed in the respective electrodes, and electric conduction therebetween is maintained. Since this opening and closing device is configured such that electric conduction between the electrodes is maintained by attractive force between magnets, and a magnetic field is formed around each of the electrodes, it is possible to stably supply an electric field required for arc extinguishing to an arc (10) generated by opening the space between the electrodes, and improve interruption performance.
