Abstract
Description
Technical Field
[0001] The present application relates to the field of electronic technology, and in particular to a reactive power compensation control system and a capacitor cabinet. Background Art
[0002] The reactive power compensation controller is suitable for the field of reactive power compensation and can be widely used in power systems with low-voltage inductive loads, such as reactive power compensation of low-voltage distribution networks in urban power grids, rural power grids, civil buildings, shopping malls and supermarkets.
[0003] The reactive power compensation controller is used to control the on and off of the switching switches in the power system. The switching switches are electrically connected to the capacitors. When the capacity of the capacitors in the power system is insufficient, the number of capacitors or the capacity of the capacitors can be increased to meet the user's capacitance requirements.
[0004] When the number of capacitors in the power system increases, the number of corresponding switches increases, and the number of loops in the corresponding reactive power compensation controller needs to increase. Furthermore, the capacity of the reactive power compensation controller needs to be expanded.
[0005] Currently, expanding the capacity of reactive power compensation controllers can be done by replacing them with controllers with more circuits. However, if the number of controller circuits has reached the limit, adding more reactive power compensation controllers is necessary, which is costly and inconvenient. Utility Model Content

[0040] In this application, "at least one" refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a alone, b alone, or c alone can represent: a alone, b alone, c alone, a and b in combination, a and c in combination, b and c in combination, or a, b, and c in combination, where a, b, and c can be single or multiple. In addition, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.
[0041] The directions or positional relationships indicated by terms such as "center", "longitudinal", "lateral", "up", "down", "left", "right", "front", and "back" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present application.
[0042] The terms "connected" and "connect" should be interpreted broadly. For example, "connected" or "connected" in a circuit structure can refer not only to a physical connection, but also to an electrical connection or a signal connection. For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate component, as long as the circuit is interconnected. It can also refer to internal connectivity between two components. Signal connection can refer not only to signal connection through circuits but also to signal connection through media, such as radio waves. Those skilled in the art will understand the specific meanings of the above terms in this application on a case-by-case basis.
[0043] refer to Figure 1 , Figure 1 A circuit diagram of a reactive power compensation control system provided by the present application. A first aspect of the present application provides a reactive power compensation control system 1, which is electrically connected to a switching switch and includes: a control device 11 and at least one drive device 12;
[0044] The control device 11 is electrically connected to the first port J1 of the driving device 12;
[0045] The second port J2 of the driving device 12 is electrically connected to the switching switch;
[0046] The driving device 12 is used to drive the switching switch to different states based on the control signal sent by the control device 11.
[0047] In a first aspect, the present application provides a reactive power compensation control system 1. In the reactive power compensation control system 1, a driving device 12 controls a switching switch to be in different states based on a control signal sent by a control device 11 to control the switching on and off of a capacitor.
[0048] When controlling the switching on and off of capacitors based on the reactive power compensation control system 1, since the drive device 12 and the control device 11 are both separate devices, there is no need to change the controller. Instead, it is only necessary to add, reduce, or replace the drive device 12 to match the capacitor capacity change. This effectively achieves precise switching of capacitors.
[0049] Furthermore, when controlling the input and output of capacitors based on the reactive power compensation control system 1, there is no need to add control devices to the reactive power compensation control system. Instead, the drive device only needs to be adjusted to match the number of loops required by the reactive power compensation control system. This effectively reduces line losses and significantly increases energy consumption and efficiency.
[0050] Furthermore, the power factor can be improved, the grid voltage can be stabilized, and the power supply quality can be guaranteed. In addition, when the drive device 12 is replaced, the operation is simple, and the cost and time can be effectively saved.
[0051] refer to Figure 1 In the reactive power compensation control system 1 provided herein, the control device 11 generates a control signal based on the collected information and transmits the control signal to the drive device 12. Based on the control signal, the drive device 12 controls the state of the switching switch connected to the reactive power compensation control system 1, thereby controlling the switching on and off of the capacitor electrically connected to the switching switch. Furthermore, the control device 11 is configured to provide voltage to the drive device 12.
[0052] The switching switch can be in an on state or an off state. The switching switch can be an AC contactor or a compound switch.
[0053] The control signals transmitted by the control device 11 include: a serial input signal SDI, a data output clock signal RCLK, and a data input clock signal S-RCLK. The serial input signal SDI is a data signal. The data input clock signal S-RCLK is used to determine whether the serial input signal SDI is a valid signal when it is input. A first data signal is generated based on the valid signal when the serial input signal SDI is input. The data output clock signal RCLK is used to determine whether the first data signal is a valid signal when it is output. A second data signal is generated based on the valid signal when the first data signal is output.
[0054] Based on the above, it can be known that after receiving the control signal, the driving device 12 outputs the second data signal and inputs the second data signal into the switching switch to control the state of the switching switch.

Port 1 is also electrically connected to a first end of a capacitor C, and port 5 is also electrically connected to a second end of the capacitor C. Capacitor C is an electrolytic capacitor.
[0056] The second port J2 of the driving device 12 includes port 1, port 2, port 3, port 4, port 5, port 6, port 7, port 8, and port 9. Port 1 and port 2 of the second port J2 of the driving device 12 are both used to receive a first voltage. Port 3, port 4, port 5, port 6, port 7, port 8, and port 9 of the second port J2 of the driving device 12 are respectively electrically connected to corresponding devices in the driving device 12.
[0057] The first voltage is a power supply voltage provided by the controller to the driving device 12 .
[0058] In the reactive power compensation control system 1 of the present application, the number of the driving devices 12 can be determined based on user needs and application scenarios of the reactive power compensation control system 1 .

[0062] refer to Figure 1 In a possible design of the present application, the driving device 12 includes: a first chip 121 and a second chip 122. The first chip 121 needs to meet the principle of serial parallel operation.
[0063] refer to Figure 1 In the driving device 12, since the second port of the first chip 121 cannot be directly electrically connected to the switching switch based on the second port J2 of the driving device 12, the first chip 121 needs to be electrically connected to the switching switch based on the second chip 122 and the second port J2 of the driving device 12.
[0064] refer to Figure 1 The second ports of the first chip 121 include port 1, port 2, port 3, port 4, port 5, port 6, port 7, and port 8. Port 1, port 2, port 3, port 4, port 5, port 6, and port 7 of the second ports of the first chip 121 are electrically connected to corresponding ports of the second chip 122. Port 8 of the first ports of the second chip 121 is grounded.
[0065] refer to Figure 1 The first ports of the first chip 121 include: port 9, port 10, port 11, port 12, port 13, port 14, port 15, and port 16. Among the first ports of the first chip 121, port 9 is left floating, port 10 is connected to the second voltage, port 11 is used to input the data output clock signal RCLK, port 12 is used to input the data input clock signal S-RCLK, port 13 is grounded, port 14 is used to input the serial input signal SDI, port 15 is left floating, and port 16 is connected to the second voltage.
[0066] In this application, the first chip 121 is described by taking 7-way output as an example. If more than 7 output terminals are required, the port 15 can be used as an output terminal.
[0067] The second voltage is a voltage adapted to the first chip 121 and is an operating voltage of the second chip 122 .
[0068] refer to Figure 1The first ports of the second chip 122 include port 1, port 2, port 3, port 4, port 5, port 6, port 7, and port 8. Port 1, port 2, port 3, port 4, port 5, port 6, and port 7 of the first ports of the second chip 122 are electrically connected to port 1, port 2, port 3, port 4, port 5, port 6, and port 7 of the first ports of the first chip 121, respectively. Port 8 of the first ports of the second chip 122 is grounded.
[0069] refer to Figure 1 The second ports of the second chip 122 include port 9, port 10, port 11, port 12, port 13, port 14, port 15, and port 16. Port 9, port 10, port 11, port 12, port 13, port 14, and port 15 of the second ports of the second chip 122 are electrically connected to port 3, port 4, port 5, port 6, port 7, port 8, and port 9 of the second port J2 of the driving device 12, respectively.
[0070] In addition, in the driving device 12 , the number of the first chips 121 may be determined based on the number of switching switches electrically connected to the reactive power compensation control system 1 .
[0071] refer to Figure 1 In a possible design, in the driving device 12 , the number of the first chips 121 is the same as the number of the second chips 122 .
[0072] In the driver device 12, the first chip 121 must be electrically connected to the second port J2 of the driver device 12 based on the second chip 122. Since one first chip 121 is electrically connected to the first port of one second chip 122, the number of first chips 121 and second chips 122 in the driver device 12 must be equal. This effectively ensures that the first chip 121 can drive the switching switch to different states.
