[0002] New energy, also known as unconventional energy, refers to various forms of energy other than traditional energy. It refers to energy that has just begun to be developed or is being actively studied and is yet to be promoted. Among them, solar energy is one of the most mature new energy sources. New energy grid connection converts the received solar radiation energy into high-voltage direct current through photovoltaic arrays through high-frequency direct current conversion, and then outputs sinusoidal alternating current with the same frequency and phase as the grid voltage to the grid after inversion by the inverter.

[0003] In the existing renewable energy grid-connected power generation, in order to ensure the stability of the grid-connected power, the existing technology often uses a special detection device to detect the renewable energy grid-connected power. Among them, the power quality detector is a commonly used detection equipment, such as the online power quality detection device announced by the announcement number CN220271450U. The above-mentioned power quality detector generally connects the mounting plate to the front shell of the grid-connected cabinet by screws, so as to install the power quality detector on the grid-connected cabinet. However, the screw connection is troublesome for personnel to operate and is easy to slip. Moreover, tools are required for disassembly and installation during disassembly and maintenance, which is very inconvenient. In order to solve the above-mentioned problems, a new energy grid-connected status detection device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0020] The following will be combined Figure 1-Figure 6 A new energy grid-connected status detection device according to an embodiment of the utility model is described in detail.

[0021] Example:

[0022] The utility model provides a new energy grid-connected state detection device, referring to Figure 1 As shown, it includes a new energy grid-connected cabinet 1 and a power quality detector 2. The power quality detector 2 is installed on the front shell of the new energy grid-connected cabinet 1. In this structure, the power quality detector 2 is used to detect the quality of the new energy grid-connected power, so as to assist personnel in adjusting and optimizing the power quality.

[0023] It should be noted that the new energy grid-connected cabinet 1 and the power quality detector 2 are both existing equipment, and their internal electrical components have been disclosed. This application does not improve the internal structure of the new energy grid-connected cabinet 1 and the power quality detector 2, so they will not be introduced in detail here.

[0024] refer to Figure 3 As shown, the front side of the new energy grid-connected cabinet 1 is hinged with a protective cabinet door 15. This structure uses the protective cabinet door 15 to protect the electrical equipment at the front of the new energy grid-connected cabinet 1 and prevent people from accidentally touching the power quality detector 2.

[0025] refer to Figure 3 As shown, a transparent observation window 16 is provided on the protective cabinet door 15 , and a staff can observe the operating status of the power quality detector 2 and other electrical equipment in the front of the cabinet of the new energy grid-connected cabinet 1 through the transparent observation window 16 .

[0026] refer to Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, four mounting holes 3 are provided on the front shell of the new energy grid-connected cabinet 1, and mounting plates 4 are fixedly connected on both sides of the front of the power quality detector 2. Two waist-shaped holes 5 are provided on the mounting plates 4, and a front convex plate 6 is constructed in the middle of the two mounting plates 4. The front convex plate 6 is provided with a U-shaped groove 7, and a screw 8 is clamped in the U-shaped groove 7. A dovetail nut 9 is threadedly connected to the screw 8. One end of the screw 8 is rotatably connected to a connecting seat 10, and a baffle 11 is fixedly connected to the bottom of the connecting seat 10. Both sides of the baffle 11 are fixedly connected with a latch 12, which passes through the mounting hole 3 and the waist-shaped hole 5. The outer wall diameter of the latch 12 is adapted to the diameter of the mounting hole 3, and a locking groove 13 is clamped on the latch 12, which is locked with the inner side of the mounting hole 3. This structure is safe When installing the power quality detector 2, the personnel insert the two pins 12 on the baffle 11 into the waist-shaped hole 5 of the mounting plate 4 and the mounting hole 3 on the new energy grid-connected cabinet 1 in sequence, and then rotate the dovetail nut 9 on the connecting seat 10 to get it into the U-shaped groove 7 of the front convex plate 6, and then rotate the dovetail nut 9 on the screw 8, so that the locking groove 13 of the pin 12 is stuck at the inner side of the mounting hole 3, and continue to rotate the dovetail nut 9 until the locking groove 13 of the pin 12 tightly locks the mounting plate 4 on the front shell of the new energy grid-connected cabinet 1, thereby connecting the power quality detector 2 to the new energy grid-connected cabinet 1, and the reverse operation can be performed during later disassembly and assembly. Compared with the screw connection, the above-mentioned installation structure of the power quality detector 2 has high installation efficiency and is convenient for later disassembly and maintenance.

[0027] refer to Figure 5 As shown, the lock slot 13 is a trapezoidal structure. The lock slot 13 of this trapezoidal structure can realize the locking connection between the latch 12 and the shell of the new energy grid-connected cabinet 1, and can also realize the locking installation of the new energy grid-connected cabinet 1 with shells of different thicknesses.

[0028] refer to Figure 3 and Figure 4 As shown, a socket 14 adapted to the power quality detector 2 is provided on the front shell of the new energy grid-connected cabinet 1, and the power quality detector 2 is inserted into the socket 14. The socket 14 on the new energy grid-connected cabinet 1 with this structure facilitates the power quality detector 2 to be inserted into the front shell of the new energy grid-connected cabinet 1, and plays a role in positioning the installation position of the power quality detector 2.

[0029] It should be noted that the above-mentioned power quality detector 2 is applied to the detection of the grid-connected status of new energy power.

[0030] The implementation principle of a new energy grid-connected status detection device of an embodiment of the present application is as follows: when installing the power quality detector 2, the personnel insert the two pins 12 on the baffle 11 into the waist-shaped hole 5 of the mounting plate 4 and the mounting hole 3 on the new energy grid-connected cabinet 1 in sequence, and then the personnel rotate the dovetail nut 9 on the connecting seat 10 to snap into the U-shaped groove 7 of the front convex plate 6, and then the personnel rotate the dovetail nut 9 on the screw 8, so that the locking groove 13 of the pin 12 is stuck at the inner side edge of the mounting hole 3, and continue to rotate the dovetail nut 9 until the locking groove 13 of the pin 12 tightly locks the mounting plate 4 on the front shell of the new energy grid-connected cabinet 1, thereby realizing the connection between the power quality detector 2 and the new energy grid-connected cabinet 1, and the reverse operation can be performed during later disassembly and assembly. Compared with the screw connection, the above-mentioned installation structure of the power quality detector 2 has high installation efficiency and is convenient for later disassembly and maintenance.
