This outdoor looped netowrk cabinet includes the cabinet body and sets up in the internal power supply box of cabinet, and the power supply box includes box 1 and sets up power module 2, monitoring module 3, terminal row 4 and circuit breaker 5 in box 1.
The inner cavity of the box body 1 comprises an upper cavity and a lower cavity, and the upper cavity comprises a first cavity and a second cavity which are arranged side by side. The power supply module 2 is disposed in the lower chamber and includes a storage battery 21 and a charging unit. The monitoring module 3 is disposed in the first chamber of the upper chamber, and is configured to control the charging unit to charge the storage battery 21, so that the storage battery 21 maintains a sufficient electric quantity, and normal operation of the power box is maintained. The terminal block 4 and the circuit breaker 5 are arranged side by side in the second chamber. The storage battery 21 is electrically connected with the electric elements in the cabinet body through the terminal strip 4 to supply power, and the circuit breaker 5 can control the on-off of the circuit in the power box to ensure the safe operation of the power box. The case 1 includes a main case 11, a front panel 12, and an upper cover 13. The front panel 12 is rotatably connected to the main box 11, and the box body 1 can be opened by rotating the front panel 12 so as to view the power supply module 2 and the monitoring module 3 above the power supply module 2. The upper cover plate 13 is detachably connected to the upper port of the main box 11, and the monitoring module 3, the terminal block 4 and the circuit breaker 5 of the upper chamber can be viewed after the upper cover plate 13 is detached, so that each component in the power box can be periodically overhauled. The structure of the power box and the arrangement of all parts are reasonable, so that the power box has a proper height-width ratio, and the internal space of the power box can be fully utilized. In addition, the power box is arranged inside the cabinet body instead of the distribution network power cabinet which is arranged outside the cabinet body and is parallel to the cabinet body, so that the occupied area can be effectively reduced, and the land resources are saved.

This embodiment provides an outdoor looped netowrk cabinet, its difference with embodiment one lies in: the power box is also provided with a communication module and a remote control module. The communication module comprises a communication interface and a network interface. When the diagnosis module automatically diagnoses circuit faults or abnormal operation states, the diagnosis module can send signals to the communication interface, and after the communication interface receives the fault signals, the fault signals are transmitted to a background of the distribution network automation system in the form of hard contacts and messages through the network interface. The information that obtains through the backstage is so that inform the maintainer to go to the place of failure, and the maintainer and then through warning lamp and the outdoor looped netowrk cabinet that the warning bell locking broke down, opens the cabinet door and can maintain its inside power supply box.
Further, the maintenance personnel can send an instruction to the monitoring module 3 of the power box through the remote control module to control the charging state of the storage battery 21, so as to ensure that the storage battery 21 has enough capacity all the time while ensuring that the storage battery 21 is not overcharged or overdischarged, so as to continuously and reliably supply power to the electrical elements in the cabinet body. Can send the instruction to the power supply box fast through setting up remote control module, need not to catch up to the scene, improve intelligent management level.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations, and substitutions will occur to those skilled in the art without departing from the scope of the present invention. This need not be, nor should it be exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
