Description

Technical Field

[0001] The utility model relates to the technical field of electrical control, in particular to a silicon chain voltage regulating device. Background Art

[0002] When the charging module is charging the battery, the output voltage may exceed the control bus voltage. At this point, the step-down silicon link plays a key role. Through automatic or manual adjustment, it reduces the excess voltage to a level that matches the control bus voltage, thereby maintaining voltage balance and normal operation across the entire system. In other words, the silicon link acts as a "voltage regulator" for the power system, ensuring voltage coordination between various components and making a significant contribution to the safety and efficiency of the power system.

[0003] With respect to the above-mentioned related technologies, the existing silicon chain voltage regulating device has the defect that the number of connected silicon chains is automatically controlled according to the size of the load. It is convenient to adjust by automation. However, this method is relatively sensitive. Slight load fluctuations can easily cause gear jumps, causing the number of connected silicon chains to change, which is not conducive to voltage stability. Therefore, the utility model provides a silicon chain voltage regulating device. Utility Model Content

[0004] The purpose of the present application is to provide a silicon chain voltage regulation device to solve the problem proposed in the above background technology of automatically controlling the number of connected silicon chains according to the size of the load. It is convenient to adjust by automation. However, this method is relatively sensitive to adjustment. Slight load fluctuations can easily cause gear jumps, causing the number of connected silicon chains to change, which is not conducive to voltage stability.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a silicon chain voltage regulation device, comprising a circuit board, a silicon chain for voltage regulation is provided on the outside of the circuit board, the silicon chain is composed of seven diodes connected in series, a plurality of relays are installed on the outside of the circuit board, an isolation diode is provided on the outside of the circuit board, the output end of the relay is connected to the output end of the diode, and an open circuit protection circuit connected to the silicon chain is provided on the outside of the circuit board.

[0006] Preferably, a circulating cooling pump is provided on the outside of the circuit board, and an output end of the circulating cooling pump is fixedly connected to a cooling pipe adapted to the outside of the diode.

[0007] Preferably, a return pipe is fixedly connected to the return end of the circulating cooling pump, and the return pipe is connected to the cooling pipe.

[0008] Preferably, a wiring box is provided on the outer side of the circuit board, and the outer side of the wiring box is coated with an epoxy resin coating.

[0009] Preferably, a plurality of mounting holes are provided on the outer side of the circuit board.

[0010] In summary, the technical effects and advantages of the utility model are:

[0011] In this utility model, the ultimate purpose of the silicon chain is to connect the control mother (supplying power to the operating circuit) and the closing mother (opening and closing the circuit breaker) to facilitate voltage regulation. When the silicon chain is operating normally, the "open circuit protection circuit" always monitors the status of the silicon chain. When an open circuit fault occurs in the silicon chain, the "open circuit protection circuit" immediately operates to short-circuit the open circuit part of the silicon chain. The remaining part of the silicon chain can still operate normally and still has the "manual" and "automatic" adjustment functions.

[0012] In the present invention, the alarm circuit is actuated to send out a silicon chain open circuit alarm signal (relay contact). There are two methods to achieve voltage reduction of the silicon chain. The first is to manually adjust it on site, directly letting the execution relay actuate and open and close the knife switch to adjust the actual length of the silicon chain. The second is to detect the voltage and compare it with the set voltage value through the logic control unit. When it is equal to or exceeds the set value, a high level (or low level) is output to make the drive circuit output an opening and closing signal, and then execute the relay action, which can also adjust the actual length of the silicon chain.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0021] Example: Reference Figure 1-4 The illustrated device includes a silicon chain voltage regulator, comprising a circuit board 1. An alarm circuit is provided on the outside of the circuit board 1. A silicon chain 9 for voltage regulation is provided on the outside of the circuit board 1. The silicon chain 9 is composed of seven diodes 4 connected in series. Multiple relays 2 are mounted on the outside of the circuit board 1. An isolation diode 5 is provided on the outside of the circuit board 1. The output end of the relay 2 is connected to the output end of the diode 4. An open-circuit protection circuit connected to the silicon chain 9 is provided on the outside of the circuit board 1. A circulating cooling pump 6 is provided on the outside of the circuit board 1. The output end of the circulating cooling pump 6 is fixedly connected to a cooling pipe 7 adapted to the outside of the diode 4. A return pipe 8 is fixedly connected to the return end of the circulating cooling pump 6. The return pipe 8 is connected to the cooling pipe 7. The circulating cooling pump 6 is controlled to direct condensate into the cooling pipe 7 to cool the diode 4, thereby preventing the diode 4 from continuously heating up during use and affecting normal use. A wiring box 3 is provided on the outside of the circuit board 1. The outside of the wiring box 3 is coated with an epoxy resin coating to improve the waterproof capability of the wiring box 3. A plurality of mounting holes 10 are provided on the outside of the circuit board 1.

[0022] In this embodiment, the input and output of the voltage-regulating silicon link in the DC panel are both DC. The silicon link is generally composed of seven diodes connected in series, with an isolation diode behind the silicon link. The ultimate purpose of the voltage-regulating silicon link is to connect the control bus (which supplies power to the operating circuit) and the closing bus (which opens and closes the circuit breaker) to facilitate voltage regulation. When the silicon link is operating normally, an "open circuit protection circuit" constantly monitors the silicon link's status. When an open circuit fault occurs in the silicon link, the "open circuit protection circuit" immediately activates, short-circuiting the open circuit portion of the silicon link. The remaining silicon link continues to operate normally, maintaining both "manual" and "automatic" regulation functions. Simultaneously, the alarm circuit activates, issuing a silicon link open circuit alarm signal (relay contact). There are two ways to reduce the voltage of the silicon link: the first is to manually adjust it locally, directly actuating the actuator relay to open and close the knife switch to adjust the actual length of the silicon link. The second is to detect the voltage and compare it with a set voltage value through a logic control unit. If it equals or exceeds the set value, a high (or low) level output causes the driver circuit to output an opening and closing signal, which then activates the relay, also achieving the actual adjustment of the silicon link length.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
