The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0024] For the current fault detection of electrical cabinets, temperature monitoring devices are usually installed at fixed points of the electrical cabinets, which can only achieve fixed-point temperature monitoring, but cannot dynamically monitor the operating state of the electrical cabinets at multiple points.

[0025] Therefore, the utility model provides a power supply system, including: a distribution box, a slide rail, a sliding contact wire, a current collector, and a mobile device. The distribution box is provided with a switching power supply for converting an AC power supply into a DC power supply. The mobile device is linked to the current collector, the current collector is slidably linked to the sliding contact wire arranged on the slide rail, and the switching power supply is electrically connected to the mobile device.

[0026] As Figure 1As shown in the figure, there is a distribution box layout diagram. The mobile device is connected to a DC power supply through the sliding contact wire and the current collector, and the DC power supply is a low-voltage DC power supply.

[0027] In the distribution box 100, there are a terminal block 10 and a circuit breaker 12. One end of the terminal block is connected to the sliding contact wire, and the other end of the terminal block is connected to the switching power supply 11; one end of the circuit breaker is connected to the switching power supply, and the other end of the circuit breaker is connected to an external power supply, and the external power supply is an AC power supply.

[0028] One end of the terminal block is connected to the sliding contact wire, and the other end of the terminal block is connected to the switching power supply; one end of the terminal block is connected to a power switch (the terminal block is connected to the switching power supply for distributing the low-voltage DC power supply), and the other end of the terminal block is used to connect to the power supply terminal of the sliding contact wire to supply power to the sliding contact wire. One end of the circuit breaker is connected to the switching power supply, and the other end of the circuit breaker is connected to an external power supply. When maintaining the equipment, the external 220V power supply can be disconnected by the circuit breaker, which is convenient for maintenance.

[0029] As Figure 2 shown in the figure, a schematic diagram of the sliding contact wire and the current collector. Inside the current collector 21, there is a conductive contact 23. The sliding contact wire 20 is provided with a copper bar 22 (the copper bar has positive and negative poles), the contact touches the copper bar, and the contact slides along the copper bar in contact. The contact has a conductive function and can be connected to the mobile device to play the role of energization; the contact of the current collector is in close contact with the copper bar of the sliding contact wire and can move.

The slide rail is provided with a groove with a certain depth. When the current collector and the mobile device move along the trolley wire, they will not touch the bolts or screws, preventing electric shock and short circuit. The electric rail clips are fixed in the groove with screws and / or bolts.
