Description

Technical Field

[0001] This invention relates to the field of power cabinet technology, and in particular to an auxiliary operating device for a 10kV ring main unit. Background Technology

[0002] 10kV ring main units have advantages such as small footprint, high operational reliability, and convenient operation. They are key electrical equipment to ensure reliable operation of lines and are therefore widely used in 10kV distribution networks. However, there are two disadvantages in the operation and maintenance of 10kV ring main units on site: (1) According to the standardized technical specifications (general part), there are clear requirements for the height of the equipment. The height of the cabinet is 2.2 meters, while the operation button for opening and closing the switch is located above the cabinet, 2 meters above the ground. However, because the button is high above the ground, the staff must expose their whole body in front of the 10kV equipment in operation to operate the button. If the switch body is faulty and explodes, it will directly threaten life; (2) Since the ring main unit integrates primary and secondary equipment, 2-3 people are needed to cooperate in the operation and maintenance of the equipment (such as multimeter, battery internal resistance detector, phase comparison device, etc.), resulting in low on-site work efficiency.

[0003] Currently, remote, contactless operation robots are being used to address the shortcomings of 10kV ring main units during on-site operation, maintenance, and maintenance.

[0004] However, this auxiliary operation robot has shortcomings, namely: (1) Strict usage conditions: It must be installed in an indoor switch station and requires auxiliary equipment such as lighting, ventilation, and heat dissipation, but it cannot be widely used in outdoor switch boxes; (2) High cost and single function: It cannot assist staff in the operation and maintenance of primary and secondary equipment, and also requires additional operation and maintenance of the robot itself, which increases labor costs instead of reducing them.

[0005] Therefore, it is necessary to provide a new auxiliary operating device suitable for 10kV ring main units, which can solve the problems of harsh operating conditions, high cost and limited functionality of traditional auxiliary operating robots. Summary of the Invention

[0006] The technical problem to be solved by the embodiments of the present invention is to provide a 10kV ring main unit auxiliary operation device, which can solve the problems of harsh operating conditions, high cost and single function of traditional auxiliary operation robots.

[0007] To address the aforementioned technical problems, this invention provides an auxiliary operating device for a 10kV ring main unit, which works in conjunction with a remote wireless controller. The device includes a housing; the housing is a closed structure formed by a top plate, a bottom plate, and multiple side walls located between the top plate and the bottom plate; wherein...

[0008] The top plate has a data display screen and multiple wiring holes mounted on its end face away from the bottom plate;

[0009] The base plate has a cylinder and four telescopic feet driven by the cylinder mounted on its end face away from the top plate. The cylinder's output shaft is connected to four sub-shafts via a control module, with each sub-shaft extending towards a corresponding corner of the base plate at its end away from the cylinder. Each telescopic foot includes a main arm and an extension arm movably connected to the main arm. The main arm is fixed to a corresponding corner of the base plate and has a magnet at its end away from the extension arm for fixing to the 10kV ring main unit. One end of the extension arm is embedded in the main arm, and the other end has contacts that cooperate with pre-installed opening and closing buttons on the 10kV ring main unit. The middle portion between the two ends is connected to a corresponding sub-shaft of the cylinder.

[0010] A transceiver antenna is provided on one of the plurality of sidewalls;

[0011] The housing integrates a circuit board, which is connected to the data display screen and the plurality of wiring holes to perform voltage, current, and phase comparison testing. The circuit board is also connected to a cylinder to operate the circuit breaker button by driving the four telescopic feet through the cylinder. The circuit board is connected to a transceiver antenna and establishes communication with a remote wireless controller to perform command transmission and reception. The circuit board is used to control the cylinder to extend one or more telescopic feet from their initial state outwards according to a first command from the wireless controller, so that the contacts on the extended telescopic feet can press against the circuit breaker button or the circuit breaker button, thereby operating the circuit breaker button or the circuit breaker button; or, according to a second command from the wireless controller, control the cylinder to retract each extended telescopic foot inwards to its initial state; or, when test leads are selected from the plurality of wiring holes for voltage, current, or phase comparison testing, the measured voltage, current, or phase comparison information is pushed to the data display screen for real-time display.

[0012] The top plate is further equipped with a remote control display screen on its end face away from the bottom plate; wherein,

[0013] The remote control display screen is connected to the circuit board to display the instruction information issued by the wireless controller when controlling the extension and retraction of the four telescopic feet; the remote control display screen is used to display the first instruction when the cylinder drives one or more of the telescopic feet to extend outward from the initial state; or, when the cylinder drives each extended telescopic foot to retract inward to the initial state, to display the second instruction.

[0014] The first instruction and the second instruction are displayed on the remote control display screen using directional arrows or text.

[0015] The cylinder is fixed to the base plate by a movable bracket.

[0016] The top plate has a transparent viewing window, and the bottom plate has another transparent viewing window located opposite the top plate.

[0017] The cylinder is fixed to the observation window of the base plate by a movable bracket.

[0018] Each of the aforementioned observation windows is made of acrylic material.

[0019] The data display screen is a liquid crystal display screen.

[0020] After the four telescopic feet are fixed to the 10kV ring main unit by magnets, a certain gap is reserved between the cylinder and the 10kV ring main unit.

[0021] The outer shell is made of hard plastic.

[0022] Implementing the embodiments of the present invention has the following beneficial effects:

[0023] 1. The auxiliary operation device of the present invention can realize the functions of testing voltage, current and phase comparison, as well as command transmission and reception. It can also realize the risk-free operation of the opening and closing buttons through remote control. Because it integrates multiple operation and maintenance functions, it effectively increases the work efficiency of operation and maintenance personnel, thereby solving the problems of harsh use conditions and single function of traditional auxiliary operation robots.

[0024] 2. The auxiliary operation device of the present invention can be repeatedly and easily installed and used, greatly reducing costs, thereby solving the problems of harsh operating conditions and high costs of traditional auxiliary operation robots. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 4 As shown in the figure, an auxiliary operation device for a 10kV ring main unit is proposed in an embodiment of the present invention. It works in conjunction with a remote wireless controller (not shown) and includes a housing 1 made of hard plastic. The housing 1 is a closed structure formed by a top plate 11, a bottom plate 12, and multiple side walls 13 located between the top plate 11 and the bottom plate 12.

[0032] The top plate 11 has a data display screen 2 (such as an LCD screen) and multiple wiring holes 3 mounted on the end face away from the bottom plate 12. It should be noted that the wiring holes 3 are configured according to the functions of the multimeter and can be used to insert test leads to perform voltage, current and phase comparison tests.

[0033] A cylinder 3 and four telescopic feet 5 driven by a cylinder 4 are mounted on the end face of the base plate 12 away from the top plate 11. The cylinder 4 is fixed to the base plate 12 via a movable bracket 9. Four branch shafts (not shown) are connected to the output shaft of the cylinder 4 via a control module (not shown), and each branch shaft extends towards a corresponding corner of the base plate 12 at its end away from the cylinder 4. Each telescopic foot 5 includes a main arm 51 and an extension arm 52 movably connected to the main arm 51. The main arm 51 is fixed to a corresponding corner of the base plate 12, and a magnet 511 for fixing to a 10kV ring main unit is provided at its end away from the extension arm 52. One end of the extension arm 52 is embedded in... In the main arm 51, the other end is provided with a contact 521 that cooperates with the pre-installed trip button (not shown) and closing button (not shown) on the 10kV ring main unit. The middle part between the two ends is connected to a corresponding branch shaft of the cylinder 4. It should be noted that the output shaft of the cylinder 4 can selectively control one or more branch shafts to extend and retract through the control module. At this time, the control module can be flexibly designed using gear sets or other combinations commonly used by those skilled in the art, which will not be elaborated here. At the same time, after the four telescopic feet 5 are fixed to the 10kV ring main unit by magnets 511, a certain gap is reserved between the cylinder 4 and the 10kV ring main unit, which is conducive to the telescopic movement of the cylinder 4.

[0034] A transceiver antenna 6 is provided on one of the multiple sidewalls 13 (such as the sidewall 13 directly below);

[0035] The outer casing 1 integrates a circuit board 7. The circuit board 7 is connected to the data display screen 2 and multiple wiring holes 3 to perform voltage, current, and phase comparison testing (equivalent to a multimeter function). Based on its control circuitry, the circuit board 7 is connected to a cylinder 4 to drive four telescopic feet 5 to operate the opening and closing buttons. The circuit board 7 is connected to a transceiver antenna 6 and establishes communication with a remote wireless controller to achieve command transmission and reception. The circuit board is used to respond to the first command (such as an extension command) issued by the wireless controller. The control cylinder 4 drives one or more telescopic feet 5 to extend outward from the initial state, so that the contact 521 on the extended telescopic foot 5 can press against the opening or closing button, thereby realizing the operation of the opening or closing button; or, according to the second instruction (such as the retraction instruction) issued by the wireless controller, the control cylinder 4 drives each extended telescopic foot 5 to retract inward to the initial state; or, when test leads are selected from multiple wiring holes 3 to perform voltage, current or phase comparison functions, the measured voltage, current or phase comparison information is pushed to the data display screen 2 for real-time display.

[0036] Understandably, the auxiliary operating device also includes a battery S, which powers all modules. This is a standard design and will not be elaborated upon here.

[0037] In this embodiment of the invention, in order to facilitate the understanding of the instruction information issued by the remote wireless controller, a remote control display screen 8 is also installed on the end face of the top plate 11 away from the bottom plate 12. The remote control display screen 8 is connected to the circuit board 7 to display the instruction information issued by the wireless controller when controlling the extension and retraction of the four telescopic legs 5. At this time, the remote control display screen 8 is used to display the first instruction by a directional arrow (upward arrow) or text ("extend") when the cylinder 4 drives one or more telescopic legs 5 to extend outward from the initial state; or, when the cylinder 4 drives each extended telescopic leg 5 to retract inward to the initial state, the second instruction is displayed by a directional arrow (downward arrow) or text ("retract").

[0038] In this embodiment of the invention, in order to facilitate observation of the movement and emptying of the cylinder 4, a transparent and visible observation window 10 is provided on the top plate 11, and another transparent and visible observation window 10 is provided on the bottom plate 12 at a position opposite to the observation window 10 on the top plate 11; wherein, each observation window 10 is made of acrylic material, and the cylinder 4 is fixed to the observation window 10 on the bottom plate 12 by a movable bracket 9.

[0039] The working principle of a 10kV ring main unit auxiliary operation device in this embodiment of the invention is as follows:

[0040] First, before the operation and maintenance work begins, the auxiliary operation device is fixed to the 10kV ring main unit to be operated by the magnets 511 of the four telescopic feet 5, and the distance from the trip button or the closing button to one or more telescopic feet 5 after they are extended is reserved.

[0041] Secondly, if on-site maintenance is required, test leads can be selected from multiple wiring terminals 3 to test voltage, current, or phase comparison functions. This allows the data display screen 2 to display the measured voltage, current, or phase comparison information in real time, effectively increasing the work efficiency of maintenance personnel. Alternatively,

[0042] If operation of the opening and closing buttons is required, the operator can move away from the 10kV ring main unit to be operated. A first command (such as an extension command) issued by the wireless controller controls the cylinder 4 to drive one or more telescopic legs 5 to extend outward from their initial state, allowing the contacts 521 on the extended telescopic legs 5 to press against the opening or closing button, thus enabling operation of the opening or closing button. Simultaneously, during the movement of the cylinder 4, the movement can be observed in real-time through the observation window 10 on the top plate 11, and the relevant information and accuracy of the first command issued by the wireless controller can be displayed on the remote control display screen 8. After the button operation is completed, a second command (such as a retraction command) issued by the wireless controller controls the cylinder 4 to drive each extended telescopic leg 5 to retract inward to its initial state. Simultaneously, during the movement of the cylinder 4, the movement can be observed in real-time through the observation window 10 on the top plate 11, and the relevant information and accuracy of the second command issued by the wireless controller can be displayed on the remote control display screen 8.

[0043] Finally, once the maintenance work is completed, the auxiliary operating device can be removed directly.

[0044] Implementing the embodiments of the present invention has the following beneficial effects:

[0045] 1. The auxiliary operation device of the present invention can realize the functions of testing voltage, current and phase comparison, as well as command transmission and reception. It can also realize the risk-free operation of the opening and closing buttons through remote control. Because it integrates multiple operation and maintenance functions, it effectively increases the work efficiency of operation and maintenance personnel, thereby solving the problems of harsh use conditions and single function of traditional auxiliary operation robots.

[0046] 2. The auxiliary operation device of the present invention can be repeatedly and easily installed and used, greatly reducing costs, thereby solving the problems of harsh operating conditions and high costs of traditional auxiliary operation robots.

[0047] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
