Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic treatment, and particularly relates to an electrostatic elimination structure for a substation area energy storage device. Background Technique

The energy storage cabinet is internally provided with a lithium-ion battery, a battery management system, an energy storage bidirectional converter, a monitoring system, a distribution box, etc., so as to collect the operation information of the battery management system, the energy storage bidirectional converter, the load, etc. in real time, so that the energy storage bidirectional converter can control the charging operation or discharging operation of the distribution substation area energy storage cabinet, improving the reliability of power supply and power quality of the distribution substation area.

[0003] However, due to the relatively scattered layout of the substation area energy storage, and most of them are placed in the open air environment, and even some locations are relatively remote, the operation and maintenance are relatively difficult, and potential safety hazards are likely to occur. During the long-term operation of the substation area energy storage, a large amount of static electricity will accumulate. If it is not eliminated in time, it is likely to pose a great safety hazard to the electrical components of the substation area energy storage. Moreover, the traditional grounding wire method is likely to fail to ensure the effect of static electricity elimination in time due to poor connection of the grounding wire, too large grounding wire resistance, or electromagnetic interference on the grounding wire, etc. There is a lack of an electrostatic elimination structure for intelligent and active elimination of static electricity, resulting in relatively general reliability of static electricity elimination of the substation area energy storage equipment, and thus a relatively large potential safety hazard of static electricity accumulation in the substation area energy storage equipment. Summary of the Invention

[0004] The utility model provides an electrostatic elimination structure for a substation area energy storage device to solve the problem of relatively large potential safety hazard of static electricity accumulation in the substation area energy storage equipment proposed in the above background technique, and reduce the safety risk during the long-term operation of the substation area energy storage.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0030] Embodiment 1

[0031] Referring to Figure 1 and Figure 2 , an electrostatic elimination structure of a substation energy storage device includes a box body 1, an intelligent electrostatic elimination mechanism 3 and an energy storage main body 13. The box body 1 is a conductor. The energy storage main body 13 and the intelligent electrostatic elimination mechanism 3 are installed in the box body 1. The box body 1 of the box body is mainly used to carry the intelligent electrostatic elimination mechanism and the energy storage main body, and provide support and protection for the energy storage main body and the intelligent electrostatic elimination mechanism. The energy storage main body 13 includes energy storage elements and auxiliary devices. The energy storage elements are energy storage devices such as batteries or capacitors, and the auxiliary devices are battery management systems, fire protection systems, etc.

[0032] The box body 1 includes a top surface, a bottom plate, and a first side wall, a second side wall, and a third side wall that are connected in sequence. A protective door 2 is movably hinged to the sides of the first side wall and the third side wall. Two connecting supports 8 are fixedly connected to the front surface of one of the protective doors 2, and two perforated lock blocks 9 are fixedly connected to the front surface of the other protective door 2. A limiting plate 10 is rotatably hinged to the inner wall of the connecting support 8. By providing the limiting plate 10, it can rotate relative to the inner wall of the connecting support 8 and then sleeve on the perforated lock block 9. Then, after inserting a lock structure on the perforated lock block 9, the two protective doors 2 can be conveniently locked. Through the connecting support 8, a rotating base surface can be provided for the limiting plate 10, thereby increasing the flexibility of use of the limiting plate 10. By providing the perforated lock block 9, it can cooperate with the limiting plate 10 to insert a lock structure, thereby conveniently locking the two protective doors 2.

[0033] Referring to Figure 2 , the intelligent static eliminator mechanism 3 includes a carrier box 301, a backup battery 302, a key controller 303, a mounting bracket 304, a static eliminator 306, a static sensor 307, a conductive frame 308, a conductive rod 309, and a conductive ring 310. The energy storage body 13, the carrier box 301, the backup battery 302, the key controller 303, the mounting bracket 304, the static eliminator 306, the static sensor 307, the conductive rod 309, and the conductive ring 310 are all located in the area enclosed by the conductive frame 308 and the bottom plate of the box body 1.

[0034] Referring to Figure 3 , the conductive frame 308 is U-shaped and includes a first mesh plate, a second mesh plate, and a third mesh plate that are connected in sequence. The first mesh plate and the third mesh plate are both perpendicular to the second mesh plate, and the first mesh plate, the second mesh plate, and the third mesh plate are all metal woven meshes.

[0035] Referring to Figure 4 , a backup battery 302 is fixedly connected to the inner bottom wall of the carrier box 301, and a key controller 303 and a mounting bracket 304 are fixedly connected to the upper surface of the carrier box 301. The lower surface of the mounting bracket 304 and the upper surface of the carrier box 301 are connected by four fastening bolts 305 to fix the mounting bracket 304 above the carrier box 301. A static sensor 307 and a static eliminator 306 are fixedly installed on the mounting bracket 304. The energy storage body 13, the backup battery 302, the static sensor 307, and the static eliminator 306 are all electrically connected to the key controller 303 through wires.

[0036] The inner side wall and the inner top wall of the box body 1 are fixedly connected together with a conductive frame 308. On the inner side wall of the conductive frame 308, two columns of conductive rods are fixedly connected vertically. Each column of conductive rods includes several identical conductive rods 309. The conductive metal surfaces of the static electricity sensor 307 and the static electricity eliminator 306 are in contact with the inner wall of the conductive frame 308. Among them, the model of the static electricity sensor can be selected as the KESD KSD-15CH type static electricity sensor, and the static electricity eliminator can be selected as the SJ-L005F type static electricity eliminator of Keyence.

[0037] The intelligent static electricity elimination mechanism 3 is used to actively and intelligently eliminate the static electricity on the energy storage body, while improving the reliability of static electricity elimination, avoiding the situation that due to the lack of the function of actively eliminating static electricity, the static electricity of the substation area energy storage equipment cannot be eliminated in time, resulting in an increase in the safety hazard of static electricity accumulation, leading to equipment failures or even fires.

[0038] One end of each conductive rod 309 away from the conductive frame 308 is fixedly connected with a conductive ring 310. Each conductive ring 310 is electrically connected to the energy storage body 13 through a wire. A conductive block 11 is fixedly connected to the second side wall of the box body 1. The conductive block 11 passes through the second side wall, and the protruding part of the conductive block 11 is fixedly connected with a static electricity guiding cable 12. The conductive block 11 is electrically connected to the energy storage body 13 through a wire. By setting the conductive block 11 and the static electricity guiding cable 12, the conductive block 11 can be electrically connected to the box body 1 and the energy storage body 13, so that after the static electricity guiding cable 12 is buried underground, it is convenient to increase the static electricity elimination channels of the entire energy storage body 13. The energy storage body 13 mainly realizes the functions of storing and supplying electricity in the substation area, and the static electricity on the energy storage body 13 can be connected to the conductive frame 308, and then cooperate with the various structures of the intelligent static electricity elimination mechanism, increasing the static electricity elimination effect of the energy storage body and enhancing its safety performance.

[0039] Connecting frames 4 are fixedly connected to the upper parts of the first side wall and the third side wall of the box body 1. A suspension rod 5 is fixedly connected to the inner wall of each connecting frame 4. By setting the connecting frame 4, the suspension rod 5 and the box body 1 can be connected. By setting the suspension rod 5, it is convenient for the lifting structure to hook and carry the entire box body 1 and its internal structure.

[0040] Refer to Figure 5 , an installation plate 6 is fixedly connected to the outer surface of the box body 1. The installation plate 6 is fixed to the lower parts of the first side wall, the second side wall and the third side wall. A number of identical installation holes 7 are opened on the installation plate 6. By setting the installation holes 7, it is possible to cooperate with external bolt structures to fixedly install the installation plate 6 at the required position, and then facilitate the fixation of the entire box body 1 and its internal structure.

[0041] The working principle of the present utility model is as follows: When in use, first electrically connect the key parts of the energy storage body 13 that are prone to accumulating static electricity to each conductive ring 310 through wires, so that the static electricity on the energy storage body 13 can be conducted to the conductive frame 308. And use the fastening bolt 305 to tightly install the mounting frame 304 and the bearing box 301, and finally make the metal conductive surfaces of the static eliminator 306 and the static sensor 307 closely adhere to the inner wall of the conductive frame 308. When the static sensor 307 detects that the amount of static electricity accumulated on the conductive frame 308 reaches the set threshold of the key controller 303, the key controller 303 acts, and the energy storage body 13 supplies power to the static eliminator 306. The static electricity accumulated on the energy storage body 13 is conducted to the static eliminator 306, and the static eliminator 306 timely eliminates the static electricity on the conductive frame 308 and the energy storage body 13. When the energy storage body 13 loses the power supply ability to the intelligent static elimination mechanism 3 due to power failure or other reasons, the key controller 303 will enable the backup battery 302 to supply power to the intelligent static elimination mechanism 3 instead of the energy storage body 13, ensuring that the static elimination mechanism 3 will not lose power and increasing the reliability of static electricity elimination.

[0042] This process is realized by the logical control method of "AND-OR-NOT gate" in the key controller.

[0043] The specific implementation method is as follows: The energy storage body 13 and the backup battery 302 are connected to the static elimination mechanism by the logical method of "AND-OR-NOT gate" in the key controller. Specifically:

[0044] The signal of the power supply of the energy storage body 13 is passed through a "NOT gate" to obtain its inverted signal, and then this inverted signal and the signal of the power supply of the backup battery 302 are input into an "AND gate", and the obtained result is output through an "OR gate" together with the signal of the power supply of the energy storage body 13. When the power supply of the energy storage body 13 is normal (high level), the output through the "OR gate" is the power supply of the energy storage body 13; when the energy storage body 13 does not supply power (low level), it becomes high level after passing through the "NOT gate", and then passes through the "AND gate" and the "OR gate" together with the signal of the power supply of the backup battery 302, and the output is the power supply of the backup battery 302. The design of the static electricity elimination structure of the entire substation area energy storage device effectively solves the problems of incomplete and untimely static electricity elimination and poor grounding risk of the current substation area energy storage device, and enhances the reliability of static electricity elimination.

[0045] Embodiment 2

[0046] The difference between this embodiment and Example 1 is that in this embodiment, the first side wall of the box body 1 is movably hinged to the first end of the protection door 2. Connecting pieces are installed on both the protection door 2 and the third side wall of the box body 1, and connection holes are opened on the connecting pieces. When it is necessary to keep the protection door in a closed state, insert a bolt or other connecting pieces into the two connection holes, or insert the locking rod of the U-shaped lock into the connection hole to lock the protection door 2.
