Description

Technical Field

[0001] This utility model relates to the field of voltage management, and in particular to a voltage compensation device for aquaculture areas. Background Technology

[0002] Aquaculture is an important means of income generation for villagers. Production equipment in fishponds, such as three-phase aerators, has characteristics of low load density and high reliability requirements. Once a power outage, phase loss, or voltage quality problem occurs, it often leads to equipment damage, mass fish deaths, and compensation disputes. Failure to promptly detect, protect against, disconnect, notify, and handle these problems can further damage electrical equipment and reduce the stability of the power grid, among other issues.

[0003] Most aquaculture areas are located in rural areas. Due to the actual situation of rural power grids, which are characterized by geographical dispersion and long power supply lines, there are often situations where the voltage is low, fluctuates greatly, and is severely unbalanced during peak electricity consumption. Furthermore, when the voltage is too low or unbalanced, a series of problems such as the inability of electrical equipment to work properly occur. Therefore, there is an urgent need to design a device that can detect and compensate for voltage to ensure the stability of the voltage input to production equipment such as three-phase aerators. Utility Model Content

[0004] The purpose of this invention is to provide a voltage compensation device for aquaculture areas. The device detects and evaluates the voltage before it is input to the load, and performs corresponding compensation based on the evaluation results. This ensures the stability of the voltage input to the load, thereby ensuring the stable operation of aquaculture equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a voltage compensation device for aquaculture areas, comprising a voltage compensator connected in a power transmission line, wherein the voltage compensator is connected in parallel with a first switch and a voltage sampler. The sampling information from the voltage sampler is transmitted to a controller and used to control the voltage compensation of the voltage compensator. By detecting and sampling the voltage before it is input to the load, and performing corresponding compensation based on the sampling results, the voltage input to the load can be stabilized, thereby ensuring the stable operation of the aquaculture equipment.

[0006] Preferably, the two ports of the voltage compensator connected to the line are respectively connected in series with a second switch and a third switch, and the voltage sampler and the first switch are connected in parallel with the voltage compensator, the second switch and the third switch.

[0007] Preferably, it also includes a base plate connected to the transmission line, the base plate having two rotary terminals electrically connected to the line, the two ports of the first switch and the voltage sampler being connected to the two rotary terminals respectively, and the first switch and the voltage sampler being fixed on the base plate, the voltage compensator, the second switch and the third switch being electrically connected to the two rotary terminals as a whole.

[0008] Preferably, the base plate is also provided with two compensation terminals, and the compensation terminals are electrically connected to the knob terminals on the same side. A second switch and a third switch are connected in series on the line connecting the compensation terminals and the knob terminals, and the second switch and the third switch are fixed on the base plate. The voltage compensator is electrically connected to the two compensation terminals.

[0009] Preferably, the base plate is provided with a positioning pin, the mounting plate of the voltage compensator is provided with a positioning hole, and the positioning pin passes through the positioning hole and is locked by a locking nut. The voltage compensator has two compensation wiring sleeves that are electrically connected to the compensation terminal and are sleeved together.

[0010] The technical effects of this utility model are as follows:

[0011] 1. Before the voltage is input to the load, the voltage is detected and measured, and appropriate compensation is made according to the measurement results. This can ensure the stability of the voltage input to the load, thereby ensuring the stable operation of the fishery equipment.

[0012] 2. The first switch allows the voltage compensator to be temporarily removed from the power grid for maintenance or repair without interrupting the main circuit. If the voltage stabilizing device malfunctions or needs replacement, the bypass switch can be used to bypass it, ensuring continuous power supply from the grid.

[0013] 3. The design of several sets of terminals, combined with the overall installation structure of the voltage compensator, allows the voltage compensator to be connected and disconnected from the terminals without contact, further ensuring the removal and installation of the voltage compensator without interrupting the main circuit.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0019] like Figure 1 As shown, this utility model discloses a voltage compensation device for aquaculture areas, including a voltage compensator 9 connected in a power transmission line, and the voltage compensator 9 is connected in parallel with a first switch 3 and a voltage sampler 4. The sampling information of the voltage sampler 4 is transmitted to the controller and used to control the voltage compensation of the voltage compensator 9.

[0020] The voltage sampler collects the voltage level of the power grid and transmits the collected information to the controller. The controller analyzes the data. If the voltage is within the normal range, no action is taken. If the voltage exceeds the normal range, a command is transmitted to the voltage compensator 9, which then operates to adjust the voltage range so that the input voltage to the fishery equipment remains at the normal value.

[0021] like Figure 1-3 As shown, the two ports of the voltage compensator 9 connected to the line are respectively connected in series with the second switch 5 and the third switch 7, and the voltage sampler 4 and the first switch 3 are connected in parallel with the voltage compensator 9, the second switch 5 and the third switch 7.

[0022] During use, voltage compensator 9 may age or malfunction, thus requiring maintenance. To ensure the safe removal of voltage compensator 9 and normal power transmission after removal, the above structure is designed. When removing voltage compensator 9, simply close the first switch 3, and then open the second switch 5 and the third switch 7. In this way, the current will be transmitted along the line of the first switch 3 to the device. After the installation of voltage compensator 9 is completed, close the second switch 5 and the third switch 7, and then open the first switch 3.

[0023] like Figure 2-3As shown, this application also designs a specific installation structure for the compensation device, including a base plate 1 connected to the transmission line. The base plate 1 has two rotary terminals 2 electrically connected to the line. The two ports of the first switch 3 and the voltage sampler 4 are respectively connected to the two rotary terminals 2, and the first switch 3 and the voltage sampler 4 are fixed to the base plate 1. The voltage compensator 9, the second switch 5, and the third switch 7 are also electrically connected to the two rotary terminals 2. The base plate 1 also has two compensation terminals 6, and the compensation terminals 6 are electrically connected to the rotary terminals 2 on the same side. The voltage compensator 9 is electrically connected to the two compensation terminals 6. A second switch 5 and a third switch 7 are connected in series on the circuit that connects the compensation terminal 6 and the knob terminal 2. The second switch 5 and the third switch 7 are fixed on the base plate 1. The voltage compensator 9 is electrically connected to the two compensation terminals 6. The base plate 1 is provided with a positioning plug 8. The mounting plate of the voltage compensator 9 is provided with a positioning hole. The positioning plug 8 passes through the positioning hole and is locked by a locking nut 10. The voltage compensator 9 is electrically connected to two compensation terminal sleeves 11 that are sleeved and connected to the compensation terminals 6.

[0024] The specific installation process is as follows: First, fix the base plate 1 and connect it to the power transmission line. Then, install the end interfaces of the first switch 3 and the voltage sampler 4 onto the knob terminal 2 and tighten them to ensure electrical connection between the end interfaces and the knob terminal 2. At this time, the first switch 3 is in the off state, and the second and third switches are also in the off state. Next, install the voltage compensator 9. First, the mounting plate of the voltage compensator 9 is passed through the positioning pin 8 to complete the positioning. Then, attach the voltage compensator 9 to the base plate 1 so that the compensation wiring sleeve 11 can be sleeved with the compensation terminal 6. Then, simply lock the mounting plate of the voltage compensator 9 onto the base plate 1 with the lock nut 10 to ensure a stable electrical connection between the compensation wiring sleeve 11 and the compensation terminal 6. This method of connecting the voltage compensator 9 without touching the wiring ensures that even if the operator forgets to disconnect the second and third switches when removing the voltage compensator 9, no serious safety accident will occur.
