摘要： An automatic transfer switch (10) and a contact system (100) for automatic transfer switch are disclosed. The contact system includes a first stationary contact (150), a second stationary contact (180) and a movable contact (120). The movable contact is movable between a first contact position and a second contact position, in the first contact position of the movable contact, the movable contact is in contact with the stationary contact engagement part of the first stationary contact, and, in the second contact position of the movable contact, the movable contact is in contact with the stationary contact engagement part of the second stationary contact. At least one stationary contact of the first stationary contact and the second stationary contact includes: a first part (162), extending in a vertical direction and including a first vertical end and a second vertical end; and a second part (164), extending in a horizontal direction and including a first horizontal end and a second horizontal end, the first vertical end of the first part meets the first horizontal end of the second part, and a chamfered corner is formed at a joint position of the first part and the second part of the at least one stationary contact. The automatic transfer switch includes one or more contact systems.

摘要： Disclosed are an electromagnet driving mechanism 100, an electromagnet driving assembly and a dual power automatic transfer switch. The electromagnet driving mechanism comprises: a mechanism frame 140; a stationary core 130; a movable core 120, including a moving stroke between a first position away from the stationary core and a second position in contact with the stationary core, the moving stroke including an approaching stroke section; a coil, configured to generate a magnetic attraction force between the stationary core and the movable core upon being energized to drive the movable core to move towards the second position; a reset spring member 112; and a reset auxiliary assembly 150, including a push member 152 and a reset auxiliary spring 154. The reset auxiliary assembly applies a reset auxiliary spring force to the movable core in the approaching stroke section through the push member. The dual power automatic transfer switch includes: an electromagnet driving mechanism assembly; a first stationary contact and a second stationary contact; a movable contact; the electromagnet driving mechanism assembly drives the movable contact to move among a first contact position, a double-separation position and a second contact position.

摘要： A clutch mechanism for automatic transfer switching equipment includes a main switch spindle, a manual operating mechanism spindle, and a separation actuation component. The main switch spindle includes a first moving component. The manual operating mechanism spindle includes a second moving component. When the first moving component of the main switch spindle engages the manual operating mechanism spindle, the manual operating mechanism spindle rotates with the main switch spindle. When the separation actuation component actuates the second moving component to separate the first moving component from the manual operating mechanism spindle, the manual operating mechanism spindle disengages from the main switch spindle, and the manual operating mechanism spindle and the main switch spindle rotate freely relative to each other. An automatic transfer switching equipment including the clutch mechanism is also provided.
