摘要： A motor control center includes an enclosure comprising an isolation switch, a main contactor device, and a ground switch device. The isolation switch is selectively manually operable between a connected state and a disconnected state. In the connected state the isolation switch is adapted to conduct electrical power from an associated power source to the main contactor device and wherein the isolation switch in the disconnected state interrupts conduction of electrical power from the associated power source to the main contactor device. The main contactor device is selectively operable between a conductive state and a non-conductive state, wherein the main contactor device is adapted to electrically connect the isolation switch to the ground switch device and to an associated electrical load when the main contactor device is in its conductive state and wherein the main contactor device disconnects said isolation switch from the ground switch device and the associated electrical load when the main contactor device is in its non-conductive state. The ground switch device is manually operable from an open, ungrounded state in which the main contactor device is electrically disconnected from a ground path to a closed, grounded state in which the main contactor device is electrically connected to the ground path. The motor control center further includes an interlock device operably connected between the isolation switch and the ground switch device, wherein the interlock device prevents movement of the isolation switch from the disconnected state to the connected state when the ground switch device is in the grounded state.

摘要： An apparatus includes an enclosure, a power switch, an absence of voltage detector controller, and an absence of voltage detector. The power switch is mounted inside the enclosure and configured to switch electrical power from a line-side power line to a load-side power line. The load-side power line is configured to transfer the electrical power outside of the enclosure to an industrial control panel. The absence of voltage detector controller is configured to determine a presence and an absence of each of a plurality of phases of the electric power on the load-side power line inside the enclosure. The absence of voltage detector is visible from external to the enclosure, has a switch, and is configured to illuminate one or more lamps indicating the absence of the electrical power on a corresponding one or more of the plurality of phases in response to a pressing of the switch.

摘要： The present invention discloses a dual-power overlapped closing operation mechanism, relating to the field of dual-power switches. The dual-power overlapped closing operation mechanism comprises a first contact, a second contact, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, a seventh connecting rod, a first auxiliary shaft, a second auxiliary shaft and a third auxiliary shaft. The fourth connecting rod rotates anticlockwise to push, via the fifth connecting rod and the seventh connecting rod, the second contact to make electrical contact with the second fixed contact, and at the same time the first contact is first tightly pressed via the second connecting rod and the third connecting rod until the dead point is passed, and then the first contact is gradually opened clockwise. The result of the fourth connecting rod rotating clockwise is similar, in which the second contact is first tightly pressed until the dead point is passed, and then the second contact is gradually opened clockwise. With the present invention, the neutral line overlapping has an extended duration and is maintained by means of a mechanical structure so as to effectively avoid the occurrence of a zero line break.

摘要： Implementations of the subject matter described herein provide a switching apparatus including an energy storage changement mechanism that can realize the main shaft energy storage and direction changement by using only one solenoid. Furthermore, the switching apparatus can be adopted in both two position ATS and three position ATS to satisfy different application scenarios or different market requirements. In addition, all transfers can be achieved by independent manual and electric operation, and each transfer action only requires powering a single solenoid.
