[0002] As an important part of the power grid, overhead lines play an important role in the power grid system. Among them, low-voltage overhead lines are common distribution lines in life, which are generally laid on poles or towers. According to safety regulations, such lines need to perform power outages, power testing, discharge, grounding and other operations during operation and maintenance.

[0003] For overhead line grounding operations, since the height of electric poles and iron towers is generally not less than 8m, according to the regulations for high-altitude operations, workers need to wear safety belts, foot buckles and other safety protection tools to climb the poles. The process of workers climbing the poles and towers is labor-intensive, time-consuming and labor-intensive, and high-altitude operations are difficult and dangerous. In addition, the grounding wires must be hung in strict accordance with the order of "first low and then high, from near to far". There are generally control cables and communication cables on low-voltage poles and towers. The partition cables greatly increase the difficulty of the operation, resulting in low operation efficiency.

[0004] In recent years, with the continuous improvement of residents' living standards, citizens have put forward higher requirements for the stability and reliability of power supply quality. As one of the effective means to ensure the quality of power supply, non-stop operation technology has developed rapidly. At present, most of the non-stop operation technology means are to use generator trucks to temporarily supply power to ensure the normal operation of the line. However, some areas do not have the conditions for the passage of large vehicles such as generator trucks, which makes it difficult to operate in some areas. Summary of the invention

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0033] Example 1

[0034] Reference Figure 1, which is the first embodiment of the present invention, and this embodiment provides a grounding device that can transfer power. The grounding device that can transfer power includes a grounding component 100 and a transfer power component 200. The one-button grounding function is realized by the grounding component 100, and the transfer power function is realized by the transfer power component 200.

[0035] Specifically, the grounding assembly 100 includes a switch 101 and a copper busbar 102 disposed inside the box 300. The outgoing line side of the switch 101 connects four phases through the copper busbar 102.

[0036] Preferably, the power supply assembly 200 includes a circuit breaker 201 and a quick plug 202, and the incoming line side of the circuit breaker 201 is connected to the ground wire through a wiring copper bar 102.

[0037] When in use, the wire enters from the side of the box 300 and is connected to the incoming line side of the knife switch 101 in sequence according to the phase sequence. The outgoing line side of the four phases is connected to the grounding wire. When the line needs to be grounded, the switch of the knife switch 101 is closed to directly conduct the current to the ground, realizing the rapid grounding function;

[0038] The load is connected to the current side of the circuit breaker 201, and the incoming line side at the top of the circuit breaker is connected to the knife switch through the copper bar. When temporary power transfer is required, the wire is drawn from the live side and connected to the copper bar, and then supplied to the load in the power outage area through the circuit breaker, thereby realizing the power transfer function. However, before using this function, the knife switch 101 must be turned to the open position.

[0039] Example 2

[0040] Reference Figures 1 to 5 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, the overhead line is connected to the grounding device through a conductor, and is connected to the wiring copper bus 102 inside the grounding device in sequence according to phase sequence.

[0042] Preferably, a monitoring unit 301, a display screen 302, an indicator light 303, an electromagnetic lock 304, a fuse 305 and an electromagnetic relay 306 are provided in the box 300, wherein the electric cabinet box 300 is welded together as a whole, the cabinet door and the box 300 are connected by a movable hinge, and the remaining accessories are connected by bolts.

[0043] Preferably, the initial state: the switch 101 is separated, and the circuit breaker 201 is disconnected.

[0044] Preferably, in the grounding state, the switch 101 is closed and the circuit breaker 201 is disconnected.

[0045] Preferably, the power supply state is changed: the switch 101 is separated and the circuit breaker 201 is closed.

[0046] When in use, the system can be used to process work tickets online, simplify the approval process, and improve work efficiency. In addition, the display screen 302 can observe the voltage, current and other information of the product in real time, and can grasp the product status in time.

[0047] Example 3

[0048] Reference Figures 5 to 7 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0049] Specifically, the switch 101 is closed, and the switch 201 is separated to achieve the grounding state;

[0050] The switch of knife switch 101 is separated, and the switch of circuit breaker 201 is closed to realize the power supply state.

[0051] Preferably, after the switch 101 is closed, the current is introduced into the ground through the switch 101, and the line connected to the circuit breaker 201 on the other side is disconnected.

[0052] Preferably, to realize the power transfer function, the knife switch 101 must be in the open state.

[0053] When using, Figure 5 As shown, the overhead line is connected to the device through a wire, which enters the electric cabinet from the side of the device and is connected to the copper busbar inside the device in sequence according to the phase sequence. When in use, a specific function is achieved by closing the corresponding switch.

[0054] like Figure 6 The figure shows the wiring diagram for realizing the one-button grounding function. After connecting to the overhead line, when the line needs to be grounded, the line grounding and maintenance can be realized by directly closing the switch 101. The operation is simple, convenient and fast. After the switch 101 is closed, the current is introduced into the ground through the switch 101, and the line connected to the circuit breaker 201 on the other side is disconnected.

[0055] like Figure 7 The figure shows the wiring diagram for realizing the power transfer function. After the line is connected, when other loads need to be powered temporarily, the load line can be connected by directly closing the circuit breaker 201 switch to complete the power transfer operation. The current flows to the equipment that needs power through the circuit breaker. Note: To realize the power transfer function, the knife 101 switch must be in the open state.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
