Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0034] Please refer to Figure 1 to Figure 2 The embodiment of the present application provides a low-voltage grounding system that can be installed with power on. The low-voltage grounding system that can be installed with power on (hereinafter referred to as the low-voltage grounding system) includes a transformer control switch A08 and an electronic switch lock A04.

[0035] The transformer control switch A08 is used to connect the four-phase wires ABCN in a live state, and connect a wire through the connecting piece 500 as a ground wire; the electronic switch lock A04 is used to control the on and off of the four-phase wires ABCN and the ground wire through a paired electronic key. That is, the electronic switch lock A04 can control the on and off of the four-phase wires ABCN and the ground wire through the authorized electronic key A05.

[0036] Among them, the ABCN four-phase line is a three-input four-phase line.

[0037] refer to Figure 1 , providing an anatomical diagram of a live low-voltage grounding system, wherein the internal wiring layer includes a fixing area for electrical components and connecting wires, and the external operating layer is provided with an electronic switch lock A04, an indicator light A02, an electric test interface A01 with an insulating cover, and a first terminal 100 for introducing an ABCN four-phase line and a second terminal 300 for introducing a grounding wire. The first terminal 100 can introduce an ABCN four-phase line through a wiring clamp, and the second terminal 100 can introduce a grounding wire through a wiring clamp. A waterproof fixing device 101 is provided on the first terminal 100 for fixing the first terminal 100.

[0038] Specifically, Figure 2 As shown, the substation control switch A08 has multiple wiring ports 600 built in, through which the first wiring terminal 100 can be led out, and the ABCN four-phase line can be connected through the first wiring terminal 100, and the second wiring terminal 300 can be led out by connecting the connecting piece 500, and the grounding line can be connected through the second wiring terminal 300, so that after the electronic switch lock A04 is opened, the substation control switch A08 controls the internal switch 700 to achieve precise control of the disconnection and connection of the ABCN line and the grounding line. Exemplarily, when the electronic switch lock is opened, the substation control switch A08 is rotated to the left, and the switch 700 of the substation control switch A08 is opened, and the ABCN line and the grounding line are immediately disconnected; when the substation control switch A08 is rotated to the right, the switch 700 of the substation control switch A08 is closed, and the ABCN line and the grounding line are immediately connected. The connecting piece can be a copper sheet.

[0039] It should be noted that only authorized electronic keys can open the electronic switch lock, thus ensuring the safety of the low-voltage grounding system that can be installed with power. The authorized electronic key indicates that the electronic key is paired with the electronic switch lock. Through intelligent authorization control, it can effectively prevent misoperation and malicious operation, thereby ensuring the stable operation of the power system.

[0040] The electronic switch lock has hexadecimal code stored inside to ensure no duplicate numbering, and can achieve unique code representation, which is conducive to achieving greater safety and reliability in the process of mutual communication and verification with the authorized electronic key, greatly reducing the probability of the electronic switch lock not being opened and the probability of not being opened repeatedly, and effectively preventing misoperation. By eliminating the risks brought by misoperation and malicious operation, the present application can quickly realize the transfer and maintenance operation of the low-voltage line, without the need for high-risk climbing operations, thereby significantly reducing the operational risks. In addition, the present application ensures that only personnel with clear authorization can perform opening and closing operations on the low-voltage grounding system (i.e., ABCN lines and), improving operational safety. It is conducive to greatly improving work efficiency, reducing the workload of operation and maintenance personnel, and significantly shortening power outage time.

[0041] Optionally, the electronic switch lock is an intelligent passive electronic switch lock.

[0042] Alternatively, if Figure 3 As shown, the intelligent passive electronic switch lock is encapsulated inside the waterproof protection structure 200.

[0043] The waterproof protection structure 200 is fixed to a structure that needs to be grounded, such as a utility pole, through a box fixing assembly 400. The three-input four-phase line is connected to the first terminal 100, and the grounding line is connected to the second terminal 300.

[0044] Among them, the intelligent passive electronic switch lock is made of high-strength engineering plastic material (polyamide, polycarbonate, polyoxymethylene, modified polyphenylene ether and thermoplastic polyester), has a reasonable structural design, is installed inside a waterproof protective structure, and does not require power supply.

[0045] Specifically, Figure 3 As shown, the waterproof protection structure 200 can be a waterproof box. The waterproof protection structure has waterproof performance, and the compact structure is conducive to the use of the low-voltage grounding system in different environments, such as outdoor environments or indoor environments.

[0046] In the process of encapsulating the intelligent passive electronic switch lock in the waterproof protection structure, two sets of upper and lower wiring interfaces are provided on the waterproof protection structure, which are the first wiring terminal and the second wiring terminal respectively. That is, in one embodiment, the waterproof protection structure is provided with the first wiring terminal and the second wiring terminal, the first wiring terminal is used to introduce the ABCN four-phase line, and the second wiring terminal is used to introduce the ground wire.

[0047] Optionally, the waterproof protection structure adopts a double-layer design, with the interior being a fixed installation area for electrical components and connecting wires, and the exterior being a display area for an electrical test interface and indicator lights.

[0048] like Figure 4 As shown, the waterproof protection structure 200 includes an internal wiring layer and an external operation layer, and the external operation layer is provided with an external power test interface A01, an indicator light A02, and an electronic switch lock A03, etc. The internal wiring layer is used as a fixed installation area for electrical components and connecting wires. The external operation layer is a display area for the power test interface, the indicator light, and the electronic switch lock, etc. The upper end of the waterproof protection structure 200 is provided with a hole for passing the first terminal 100, and the lower end of the waterproof protection structure 200 is provided with a hole for passing the second terminal 300.

[0049] In this embodiment, through the double-layer design, the internal structure is fixed and installed conveniently, and the waterproof protection structure can be prevented from being damaged, thereby improving the safety and reliability of the energized low-voltage grounding system, and making the operation of low-voltage grounding operations more convenient and efficient.

[0050] In one embodiment, if Figure 4 As shown, the indicator light A02 uses different colors to correspond to the phase sequence grounding conditions, that is, when the power is on, the light is off, otherwise, the light is on. The power test interface A01 is provided with an insulating cover. When power test is required (that is, before low-voltage grounding operation is required), the insulating cover is opened and the power test interface A01 is tested by the tester.

[0051] Optionally, the electronic key has buzzing and indicator light flashing prompt functions.

[0052] Optionally, the housing of the electronic key is provided with an anti-slip hole (not shown) to facilitate inspection work of different types of work, and at the same time has protection measures such as overvoltage protection, overcurrent protection, lightning protection, and anti-static protection, which is conducive to improving the intelligence level of the low-voltage grounding system.

[0053] In this embodiment, when the low-voltage grounding system is working, it has the dual functions of buzzing and indicator light flashing, which subverts the style of traditional box locks.

[0054] refer to Figure 4-Figure 5 Optionally, the system further comprises:

[0055] The intelligent authorization management platform A06 communicates with the electronic switch lock A03 and the electronic key A05 to manage and control the electronic switch lock A03 and the electronic key A05.

[0056] Among them, the intelligent authorization management platform has a parametrically designed human-computer interaction interface, which is used to represent the subordinate relationship between the working area and the staff and the relationship between the low-voltage grounding system and the staff.

[0057] Optionally, the relationship between the low-voltage grounding system and the staff is represented by a tree structure, which is conducive to intelligent query of operation logs according to time and realizes the traceability of each low-voltage grounding operation.

[0058] When low-voltage grounding operations are required, the electronic key can be authorized through the intelligent authorization management platform. After the electronic key is successfully authorized, the authorized electronic key can be used to unlock or lock the electronic switch lock. In addition, the intelligent authorization platform has strong compatibility and can support the installation of multiple operating systems, which facilitates the implementation of low-voltage grounding operations.

[0059] In order to improve the data security of the low-voltage grounding system, the intelligent authorization platform adopts two-level permissions of administrator and operator to realize authorization and authorization. That is, in one embodiment, the intelligent authorization management platform has two-level permission management functions of administrator and operator.

[0060] like Figure 6As shown, the relationship between the intelligent authorization platform, the electronic switch lock and the electronic key is demonstrated. Specifically, the administrator authorizes the electronic key held by the operator of the subordinate through the human-computer interaction interface of the intelligent authorization management platform. The operator uses the authorized electronic key to open the electronic switch lock and realizes the grounding opening and closing (i.e., the on-off between the ABCN four-phase line and the grounding wire) by controlling the substation control switch on the electronic switch lock. In this embodiment, by introducing the intelligent authorization control mechanism and the substation control switch mode, the safety and ease of operation of the low-voltage grounding system are effectively improved. The waterproof intelligent passive electronic switch lock ensures that only authorized electronic keys can operate the low-voltage grounding system, greatly reducing the risk of misoperation. At the same time, the waterproof protection structure and double-layer structure design of the device improve its environmental adaptability and the protection of internal components. It can be seen that the low-voltage grounding system provided by the present application has been significantly improved in terms of safety, efficiency and reliability, providing strong technical support for the maintenance of the power system.

[0061] See also Figure 7 , the task is assigned to the operator through the management center (i.e., the authorization management platform), and the operator takes out the electronic key. If the task is a temporary task, the electronic switch lock is opened by the authorized electronic key to perform equipment maintenance (low-voltage grounding operation). At the same time, the low-voltage grounding system records the control time and the name of the power equipment. After the equipment maintenance is completed, the electronic switch lock is closed by the authorized electronic key. At the same time, the low-voltage grounding system records the recovery time and the name of the power equipment. The operator returns the key, and the low-voltage grounding system uploads the control time and the name of the power equipment and the recovery time and the name of the power equipment to the authorization management center for query and statistics. If the task is a temporary task, the electronic key can be remotely authorized by a mobile electronic device through Bluetooth or other means, and the log data is recorded and uploaded to the authorization management platform. Then, the electronic switch lock is opened by the authorized electronic key to perform equipment maintenance (low-voltage grounding operation). After the equipment maintenance is completed, the electronic switch lock is closed by the remotely authorized electronic key, and the log data is recorded and uploaded to the authorization management platform. The operator returns the key, and the authorization management platform is used to query and / or count the log data.

[0062] Optionally, the intelligent authorization management platform can be managed in three levels, that is, different work areas are divided and managed by different operators; the upper-level management operator can start and stop all electronic switch locks at the level below him (that is, authorize and cancel authorization); operators at the same level cannot start and stop each other's electronic switch locks, that is, operators at the same level cannot authorize or cancel each other's electronic switch locks.

[0063] The switch control method of the low voltage grounding system provided by the embodiment of the present invention can be applied in the following aspects: Figure 5In the application environment. The intelligent authorization platform A06 can set the pairing relationship between the electronic switch lock and the electronic key; based on the pairing relationship, the electronic key is authorized so that when performing low-voltage grounding operations, the switch of the electronic switch lock is controlled by the authorized electronic key, and after the electronic switch lock is opened, the on-off of the ABCN four-phase line and the grounding line is controlled by the electronic switch lock. In the present invention, the electronic switch lock is opened by the paired electronic key, and then the opening and closing of the substation control switch is controlled by the electronic switch lock to control the on-off of the ABCN four-phase line and the grounding line, which greatly reduces the probability that the electronic switch lock is not opened and the probability that it is not opened repeatedly, effectively prevents misoperation, and by reducing the risks brought by misoperation and malicious operation, it can quickly realize the transfer and maintenance operation of the low-voltage line, without the need for high-risk climbing operations, thereby significantly reducing the operation risk. In addition, the present application ensures that only authorized electronic keys can perform opening and closing operations on the low-voltage grounding system (i.e., the on-off of the ABCN line and the grounding line), improves the safety of the operation, is conducive to greatly improving work efficiency, reducing the workload of operation and maintenance personnel, and significantly shortening the power outage time.

[0064] See also Figure 8 As shown, Figure 8 A flow chart of a switch control method for a low-voltage grounding system provided in an embodiment of the present invention is provided. The method can be applied to the authorization management platform A06. This embodiment is illustrated by applying to the authorization management platform A06. The switch control method for the low-voltage grounding system includes the following steps:

[0065] 101: Set the pairing relationship between the electronic switch lock and the electronic key.

[0066] The pairing relationship may be represented by the same unique code granted by the authorization management platform to the electronic switch lock and the electronic key respectively.

[0067] 102: Authorize the electronic key based on the pairing relationship so that when performing low-voltage grounding operations, the electronic switch lock can be controlled by the authorized electronic key, and after the electronic switch lock is turned on, the on and off of the ABCN four-phase lines and the grounding line can be controlled by the electronic switch lock.

[0068] Among them, the electronic key is authorized by a unique code so that when performing low-voltage grounding operations, the switch of the electronic switch lock is controlled by the authorized electronic key, and after the electronic switch lock is turned on, the on and off of the ABCN four-phase line and the grounding line are controlled by the electronic switch lock.

[0069] In the embodiment of the present application, by setting the pairing relationship between the electronic switch lock and the electronic key, and controlling the switch of the electronic switch lock by the authorized electronic key, the intelligent management of the key can be realized, and the on and off of the ABCN four-phase line and the grounding line can be controlled by the transformer control switch on the electronic switch lock, which effectively improves the safety and operation convenience of the low-voltage grounding system, ensures that only authorized personnel can operate the device, and greatly reduces the risk of misoperation.
