Description

Technical Field

[0001] The present invention relates to the technical field of remote control, and in particular to a field remote control opening and closing device for a KK switch rotating circuit breaker. Background Art

[0002] For the opening and closing operations of high-voltage switch cabinets, remote control must be adopted, and on-site live operation is not allowed. However, the circuit of the high-voltage switch cabinet is complex. After a remote control operation fails, only manual operation can be carried out: first, disconnect the upper-level power supply, isolate the power supply after power outage, and then rotate the KK switch on the high-voltage switch cabinet. This process will expand the power outage scope, increase the power outage time, and cause a large loss of load.

[0003] Therefore, at present, a technical solution is needed to solve the technical problem that when manually operating the KK switch on a high-voltage switch cabinet, it is necessary to disconnect the upper-level power supply, resulting in an expanded power outage scope, an extended power outage time, and a large loss of load. Summary of the Invention

[0004] The invention purpose of the present invention is: aiming at the technical problem in the prior art that when manually operating the KK switch on a high-voltage switch cabinet, it is necessary to disconnect the upper-level power supply, resulting in an expanded power outage scope, an extended power outage time, and a large loss of load, to provide a field remote control opening and closing device for a KK switch rotating circuit breaker.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is:

[0006] A field remote control opening and closing device for a KK switch rotating circuit breaker includes a remote control module, a processing and control component, and an actuating component. The remote control module is electrically connected to the processing and control component, and the processing and control component is electrically connected to the actuating component. The actuating component is used to be arranged on a high-voltage switch cabinet. The remote control module is used to send a control signal to the processing and control component. The processing and control component is used to receive the control signal and send an electrical signal to the actuating component. The actuating component is used to receive the electrical signal and toggle the KK switch on the high-voltage switch cabinet.

[0007] For the field remote control opening and closing device for a KK switch rotating circuit breaker of the present invention, by sending an instruction through the remote control module, the processing and control component analyzes the instruction and sends an action command to the actuating component, causing the actuating component to move and toggle the KK switch on the high-voltage switch cabinet, thereby realizing the opening and closing operations of the KK switch, avoiding on-site operation by staff and not requiring truncating the upper-level power supply, reducing the power outage scope, and improving the efficiency of troubleshooting.

[0008] As a preferred embodiment of the present invention, the remote control module includes a signal transmitting component and a signal receiving component.

[0030] In order to make the purpose, 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 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Embodiment 1

[0032] As Figures 1 - 3 shown, the on-site remote control opening and closing device of the KK switch rotary circuit breaker includes a remote control module 1, a processing and control component 2 and an actuating component 3. The remote control module 1 is electrically connected to the processing and control component 2, and the processing and control component 2 is electrically connected to the actuating component 3. The actuating component 3 is used to be arranged on the high-voltage switchgear 6.

[0033] The remote control module 1 is used to send a control signal to the processing and control component 2.

[0034] The processing and control component 2 is used to receive the control signal and send an electrical signal to the actuating component.

[0035] The actuating component 3 is used to receive the electrical signal and toggle the KK switch 61 on the high-voltage switchgear 6.

[0036] Specifically, the remote control module 1 includes a signal transmitting component 11 and a signal receiving component 12. The signal transmitting component 11 is in wireless communication connection with the signal receiving component 12, and the signal receiving component 12 is electrically connected to the processing and control component 2. The signal transmitting component 11 is the remote controller. The staff can send instructions to the signal receiving component 12 by operating the signal transmitting component 11. The signal receiving component 12 conveys the instructions to the processing and control component 2. The processing and control component 2 can be a CPU processor. After analyzing the instructions, the processing and control component 2 controls the action component 3 to perform opening and closing operations.

[0037] Specifically, the action component 3 includes a rotating component 31, and a clamping component 32 is arranged on the rotating component 31. The rotating component (31) is used to drive the clamping component (32) to rotate, and the clamping component 32 is used to clamp on the KK switch 61 to drive the KK switch 61 to rotate. The action component 3 adopts a rotating component 31 with a rotating function. By driving the clamping component 32 through the rotating component 31, the KK switch 61 is driven to rotate, so as to realize the opening and closing operations of the KK switch 61.

[0038] Among them, the rotating component 31 is a servo motor, and the rotating shaft of the servo motor is connected to the clamping component 32. The KK switch 61 has four operation positions, including opening, remote, local and closing operations. As Figure 3 shown, the change in the angle of the rotating shaft of the servo motor is proportional to the received pulse width. It can be seen from this that by sending pulses with different widths from the processing and control component 2 to the servo motor, the rotating shaft of the servo motor can be rotated by different angles, corresponding to the four operation positions of the KK switch 61, so as to realize the transformation of different operation positions of the KK switch 61.

[0039] Among them, a U-shaped card slot 321 is arranged on the clamping component 32. The clamping component 321 is clamped on the KK switch 61 through the U-shaped card slot 321.

By setting the U-shaped card slot 321 on the clamping component 32, not only can the clamping component 321 be clamped on the KK switch 61, and the KK switch 61 be driven to rotate by rotating the clamping component 321, but also the U-shaped card slot 321 has a simple structure and is very convenient for installation and disassembly on the KK switch 61.

Furthermore, when the action component 3 moves, the KK switch 61 can be driven to rotate.

[0041] Specifically, the support mechanism 4 includes a shell 41 with an opening at one end, the open side of the shell 41 is connected to the high-voltage switch cabinet 6, the KK switch 61 is located in the shell 41, and the clamping component 32 is arranged in the shell 41, so that the installation of the clamping component 32 is realized. When the shell 41 is covered on the high-voltage switch cabinet 6, the clamping component 32 is clamped on the KK switch 61, and the opening and closing operations of the KK switch 61 are realized by the rotation of the clamping component 32;

[0042] Furthermore, a mounting plate 42 is provided on the housing 41, and the signal receiving component 12 and the processing and control component 2 are both arranged on the mounting plate 42. By adding the mounting plate 42 to the housing 41, the integrated installation of the signal receiving component 12 and the processing and control component 2 is realized, so that the whole device is divided into two parts, one is the remote control part, including the signal transmitting component 11, and the other is the execution part, including the signal receiving component 12, the processing and control component 2 and the action component 3, so that the components of the execution part are assembled, the device structure is simplified, and the installation and disassembly of the device on the high-voltage switch cabinet 6 is facilitated, and the transportation and storage of the device are convenient;

[0043] Furthermore, a connecting piece 421 is provided on the support mechanism 4, and the support mechanism 4 is detachably connected to the high-voltage switch cabinet 6 through the connecting piece 421, which facilitates the disassembly and installation of the shell 41, the signal receiving component 12, the processing and control component 2 and the action component 3 on the high-voltage switch cabinet 6, and is also convenient for the maintenance of the high-voltage switch cabinet 6. Specifically, the connecting piece 421 includes a magnet, and the magnet is arranged on the side of the support device 4 connected to the high-voltage switch cabinet 6. The shell 41 and the high-voltage switch cabinet 6 can be detachably connected by adsorption of the magnet and the high-voltage switch cabinet 6. The connection and disassembly methods are very simple, which improves the working efficiency.

[0044] Furthermore, it also includes a power supply component 5, which is electrically connected to the remote control module 1, the processing control component 2 and the action component 3 respectively. The power supply component 5 is configured to provide independent power supply for each component to avoid the problem that the action component 3 cannot be started smoothly in the event of a circuit failure in the high-voltage switch cabinet 6.

[0045] The on-site remote control opening and closing device of the KK switch rotary circuit breaker of the present invention sends instructions through the remote control module 1, and the processing control component 2 analyzes the instructions and sends an action command to the action component 3, so that the action component 3 moves, and the KK switch 61 on the high-voltage switch cabinet 6 is turned to realize the opening and closing operations of the KK switch 61, avoiding the staff from performing on-site operations, and there is no need to cut off the upper-level power supply, thereby reducing the scope of power outages and improving the efficiency of troubleshooting.
