Description

Technical Field

[0001] The utility model relates to the technical field of special transformer acquisition terminals, in particular to a power supply of a special transformer acquisition terminal. Background Art

[0002] In the operation and management of smart grids, the online rate of equipment such as dedicated transformer acquisition terminals or concentrators is an important assessment indicator. When electricity users report to stop using electricity due to special reasons, such as temporary electricity use during the farming season in remote mountainous areas, or corporate users report to stop using electricity, the dedicated transformer acquisition terminals or concentrators cannot work normally during the power outage, resulting in the online rate indicator of the dedicated transformer acquisition terminals or concentrators failing to meet the assessment requirements.

[0003] The existing dual power switching power supply system (announcement number: CN218040900U) has the following defects: the above-mentioned device can realize the instantaneous power switching function when the municipal power grid is cut off, so as to ensure the normal and continuous operation of the special transformer acquisition terminal or concentrator and other equipment, but due to the small size of the special transformer acquisition terminal, it is impossible to install a large-capacity battery. The maximum power consumption of the special transformer acquisition terminal can reach 10w, which means that the 100wh battery can only maintain a maximum battery life of 10 hours. In some special cases, the power outage period may reach more than 20 hours, and the battery cannot be replaced during this period, otherwise the special transformer acquisition terminal will lose power immediately, which leads to the risk of the special transformer acquisition terminal still losing power. For this reason, the utility model is proposed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to the attached Figure 1 -Attached Figure 4 A power supply for a dedicated acquisition terminal includes an acquisition terminal body 1, a power switching component is arranged inside the acquisition terminal body 1, and the power switching component includes a terminal controller 2 arranged inside the acquisition terminal body 1, a battery compartment 101 is fixed on one side of the acquisition terminal body 1, two cavities 102 are arranged inside the battery compartment 101, a battery socket 103 is fixed on the inner bottom surface of the cavity 102, a temporary battery 104 is inserted into the battery socket 103 close to the top surface of the battery compartment 101, and a backup battery 105 is inserted into the top surface of the other battery socket 103.

[0022] In the embodiment, the terminal controller 2 is integrated with a DC voltage regulating module 201, a three-power switching unit 202, a charging module 302 and a rectifier circuit 203. The terminal controller 2 also includes a main control chip and auxiliary circuits for controlling the acquisition terminal body 1, which are all prior arts and are not described here. The temporary battery 104 and the backup battery 105 are both electrically connected to the DC voltage regulating module 201, and the municipal power grid is electrically connected to the DC voltage regulating module 201 through the rectifier circuit 203. The DC voltage regulating module 201 divides the temporary battery 104, the backup battery 105 and the municipal power grid into three routes and connects them to the three input ends of the three-power switching unit 202.

[0023] In the embodiment, a solar panel 3 is fixed to the top surface of the acquisition terminal body 1 , the solar panel 3 is electrically connected to the charging module 302 , and the backup battery 105 is also electrically connected to the charging module 302 .

[0024] In an embodiment, the municipal power grid is 220V AC power, which is converted into DC power through a rectifier circuit 203. The backup battery 105 has a DC power capacity of 80wh and a voltage of 14.8V. The temporary battery 104 has a DC power capacity of 15wh and a voltage of 3.7v. The DC voltage regulator module 201 can convert both the backup battery 105 and the temporary battery 104 into 12v DC power.

[0025] In an embodiment, a protective cover 106 is connected to one side of the battery compartment 101 via bolts.

[0026] In the embodiment, two spring sheets 4 are fixed to the inner top surface of the cavity 102 , and the two spring sheets 4 are respectively attached to the top surfaces of the temporary battery 104 and the backup battery 105 .

[0027] Working principle: When in use, when the municipal power grid loses power supply to the acquisition terminal body 1 due to a power outage, the three-power switching unit 202 responds immediately and switches the power supply to the backup battery 105, and the backup battery 105 continues to power the acquisition terminal body 1. When the backup battery 105 runs out of power and the municipal power grid still has not restored power, the three-power switching unit 202 responds immediately and switches the power supply to the temporary battery 104. At this time, the staff removes the protective cover 106 from the acquisition terminal body 1, and then buckles the backup battery 105. At this time, the shrapnel 4 rebounds, and then one end of the fully charged backup battery 105 is plugged into the battery socket 103, and the other end of the backup battery 105 is also pressed into the cavity 10 2, the spring 4 is compressed and exerts elastic force to push the backup battery 105 to be tightly plugged into the battery socket 103.
