Title:
CONTACT ROTATING SHAFT SYSTEM AND LOW-VOLTAGE SWITCH
Document Type and Number:
WIPO Patent Application WO/2017/133317
Kind Code:
A1
Abstract:
Disclosed are a contact rotating shaft system (1) and a low-voltage switch having the contact rotating shaft system (1). The contact rotating shaft system (1) comprises movable contacts (20a, 20b), rotating shafts (30a, 30b), and springs (18a, 18b) and spring through-shafts (16a, 16b). The movable contacts (20a, 20b) can rotate in cavities (308a, 308b) of the rotating shafts (30a, 30b), and the springs (18a, 18b), the spring through-shafts (16a, 16b) and bearing shafts (14a, 14b) of the movable contacts (20a, 20b) are used to lock the movable contacts (20a, 20b) with the rotating shafts (30a, 30b) so as to enable the movable contacts (20a, 20b) and the rotating shafts (30a, 30b) to form the contact rotating shaft system (1). The contact rotating shaft system (1) is configured to have a first stable position when the movable contacts (20a, 20b) and the rotating shafts (30a, 30b) are attached and a second stable position when the movable contacts (20a, 20b) and the rotating shafts (30a, 30b) are separated. The contact rotating shaft system (1) enables the movable contacts (20a, 20b) to have an anti-drop function during a separation process, thereby reducing the number and frequency of vibrations of the movable contacts (20a, 20b), reducing the heat damage to the contact rotating shaft system (1) caused by frequent contact, separation and re-contact of the movable contacts (208a, 208b) with stationary contacts in a breaking process, while also reducing short-circuit breaking time.
