Embodiment Construction

[0012] figure 1 It is an exploded perspective view of the duplex disc 10 , the duplex disc 10 includes a driving disc 12 and a driven disc 14 , the driven disc 14 includes a plurality of cavities 16 , and the size of the cavities 16 is such that it can accommodate a plurality of elastic members 18 . The driving disc 12 includes a first centering finger 20, and when the duplex disc 10 is assembled, the first centering finger 20 is placed between the first elastic member 24 and the second elastic member 26. within the gap 22. The driving disc 12 also includes a second centering finger (not shown) facing the first centering finger, which is placed between the third elastic member 28 and the fourth elastic member 30 in the second gap (not shown).

[0013] The driven plate 14 also includes a plurality of slots 32 for receiving conductors 34 having a plurality of contacts 36 mounted thereon. Each groove 32 can communicate with each other through a plurality of arc-shaped passages...

Abstract

A method for locking contacts in an automatic transfer switch is provided. The automatic transfer switch includes a plurality of pole units including a plurality of contact pairs. The method includes mounting an interior locking device in at least one pole unit and locking at least one contact pair individually with the interior locking device housed in that contact pair's pole unit.

Description

technical field [0001] This invention relates generally to electrical switches, and more particularly to automatic transfer switches. Background technique [0002] Many businesses use transfer switches to automatically switch power within second-tier operations, such as from utility power to dedicated second-tier power. Critical load units such as hospitals, airport radar towers, and high-capacity data centers rely on automatic transfer switches to provide continuous power. Typically transfer switches use multiple contacts that can be opened or closed. [0003] It is generally desirable for a transfer switch to remain closed during a fault or overcurrent condition. In a fault condition, the large and rapid influx of electrical energy results in a blow-off force between the contacts. Therefore, if not locked together, the contacts will interfere with upstream protective devices (ie, circuit breakers) and disrupt coordination between the devices. Known transfer switches in...
