Description of drawings

Fig. 1 is a structural schematic diagram of the utility model.

Among them: 1 cabinet, 2 cooling fan, 3 anti-theft alarm lock, 4 terminal block, 5 slot, 6 protective circuit board, 7 communication line input terminal, 8 communication line output terminal, 9 heat dissipation window, 10 solar battery plate.

Detailed ways

As shown in Figure 1, a kind of low-voltage comprehensive metering box of the present utility model comprises box body 1, box body 1

A protective circuit board 6 is arranged inside, and a slot 5 is arranged inside the box body 1 , and the protective circuit board 6 is inserted into the slot 5 . After the components and parts on the protective circuit board 6 are damaged, it is convenient to replace. The protective circuit board 6 is provided with a communication line input terminal 7 and a communication line output terminal 8, and an overvoltage protection module integrated on the protective circuit board 6 is connected in series between the communication line input terminal 7 and the communication line output terminal 8 , Overcurrent protection module and lightning protection module. When the communication line and the power line are short-circuited or the communication port is struck by lightning, the overvoltage and overcurrent module will play a buffer role, thus effectively avoiding the overvoltage and overcurrent damage of the terminal communication port caused by lightning strike. The box body 1 is provided with a connecting terminal row 4, and the connecting terminal row 4 is provided with a grounding terminal for the shielding layer of the communication line. It solves the problem that the shielding layer of the communication line is not easy to be grounded.

A solar battery panel 10 is arranged on the top of the box body 1 , and a temperature control device electrically connected to the solar battery panel 10 is arranged inside the box body 1 . The temperature control device includes a microprocessor, a temperature sensor connected to the microprocessor, and a heat dissipation fan 2. The heat dissipation fan 2 is arranged on the inner wall of one side of the box body 1, and a heat dissipation window 9 is arranged on the other side wall of the box body 1. When the temperature sensor detects that the temperature in the box 1 is high due to the heat dissipation of the equipment, the cooling fan 2 is controlled to turn on to reduce the temperature in the box 1 to ensure the normal operation of the electrical equipment. The solar panel 10 is used as a power supply to provide electric energy for the temperature control device, which effectively avoids the problem that the power consumption of the devices in the box body 1 affects the line loss. The box body 1 is made of aluminum foil heat-insulating coiled material, which has better heat dissipation effect.

Casing body 1 is provided with chamber door, and chamber door is provided with anti-theft alarm lock 3. Anti-theft alarm lock 3 is a new type of lock that perfectly combines electronic locks and mechanical locks and has strong anti-theft performance. It has successfully solved the two traditional problems that the mechanical lock is easy to be opened by thieves and the electronic lock is difficult to open once it fails. The anti-theft safety of the box body 1 is greatly improved.

The above description is only the preferred implementation mode of this patent. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of this patent, some improvements and replacements can also be made. These improvements and replacements It should also be regarded as the scope of protection of this patent.
