Abstract: A communication power supply system includes an alternating current power distribution module, a rectifier module, a monitoring module, a direct current power distribution module, and a signal-driven collection board. The monitoring module sends a control signal to the direct current power distribution module by using the signal-driven collection board, where the control signal is used to control the closing or opening of a circuit in the direct current power distribution module. The communication power supply system uses the monitoring module to control the direct current power distribution module, to control whether to power on the loads connected to the direct current power distribution module.

Abstract: A direct current contactor includes a case and two groups of contact components disposed in the case. Each group of contact components includes two moving contacts connected to each other and two fixed contacts. The direct current contactor further includes a drive system configured to drive the moving contacts to move in a direction close to or away from the fixed contacts, so that the moving contacts are connected to or disconnected from the fixed contacts. The case has an arc-extinguishing cavity. A first baffle in the arc-extinguishing cavity divides the arc-extinguishing cavity into a first arc-extinguishing chamber and a second arc-extinguishing chamber. The contact components are respectively located in the first arc-extinguishing chamber and the second arc-extinguishing chamber. In other words, the two groups of contact components are integrated into two arc-extinguishing chambers of one arc-extinguishing cavity and perform connection/disconnection drive by using a single drive system.

Abstract: An electromagnetic switch, including a driving apparatus and a contact apparatus. The contact apparatus includes a moving contact assembly, a chamber, and two spaced fixed contacts disposed on a top part of the chamber. The moving contact assembly includes an insulating part, a push rod, a moving contact, and an elastic part. One end of the push rod is mounted on the driving apparatus, and the other end of the push rod is mounted on the insulating part. The moving contact is mounted on one side that is of the insulating part and that is back to the push rod. The elastic part is clamped between the insulating part and the moving contact, so that the moving contact is in contact with or separated from the pair of fixed contacts under the action of the push rod.
