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: 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 power supply system includes a switch unit and an operating mechanism. The switch unit includes: an arc-extinguishing functional component, a fixed contact assembly, a moving contact, and a first magnet assembly. The arc-extinguishing functional component is located inside the arc-extinguishing functional component and can move relative to the fixed contact assembly. The operating mechanism controls the switch unit to be opened when receiving a switch-off signal, so that the moving contact is separated from the fixed contact assembly. An electric arc is formed between the moving contact and the fixed contact assembly in a separation process. Directions of at least some magnetic induction lines of the first magnet assembly intersect a current direction of the electric arc to drive the electric arc to move towards the arc-extinguishing functional component. The first magnet assembly includes a first magnet and a second magnet that are spaced apart.
