Description

Technical Field

[0001] This application relates to the technical field of battery detection, and more particularly, to a voltage acquisition device applicable to a storage battery inspection instrument and a discharge instrument. Background Art

[0002] The quality of storage batteries in the substation field is related to the power supply safety of the power system. When a power failure occurs, the storage batteries serve as backup power sources to ensure the safe operation of power facilities. When the storage batteries in the substation are working properly, each storage battery needs to be connected to a battery inspection instrument to monitor its voltage.

[0003] When the existing discharge instrument conducts a discharge test, it is necessary to set each voltage acquisition module at both ends of each storage battery. The number of storage batteries in a typical substation is between 104 and 108. Therefore, there are problems such as a large amount of wiring work and easy wiring errors during the discharge test. Summary of the Invention

[0004] This part of the content of this application is used to briefly introduce concepts, which will be described in detail in the following detailed implementation part. This part of the content of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] To solve the technical problem of easy wiring errors, this application provides a voltage acquisition device applicable to a storage battery inspection instrument and a discharge instrument, including:

[0006] An information processing module provided with a plurality of positive input terminals and negative input terminals corresponding to the positive input terminals;

[0007] A plurality of positive connection lines, one end of each positive connection line is connected to a positive input terminal, and the other end is connected to the positive electrode of the storage battery;

[0008] A plurality of negative connection lines, one end of each negative connection line is connected to a negative input terminal, and the other end is connected to the negative electrode of the storage battery;

[0009] The connection ends of the positive connection lines are provided with positive connectors having the same structure, and the connection ends of the negative connection lines are provided with negative connectors having the same structure;

[0010] The negative connector is only adapted to the negative electrode of the storage battery, and the positive connector is only adapted to the positive electrode of the storage battery;

[0011] Wherein, the voltage acquisition device applicable to the storage battery inspection instrument and the discharge instrument further includes a first switch and a second switch. The first switch is used to connect the discharge instrument, and the second switch is used to connect the inspection instrument.

[0012] In the technical solution provided by this application, by making the negative connector only adapt to the negative electrode and the positive connector only adapt to the positive electrode, the wrong connection of the circuit during connection can be avoided. At the same time, in the technical solution provided by this application, since the storage battery is connected to the information processing module, when performing voltage detection, only the first switch needs to be turned on and the second switch needs to be turned off to perform voltage detection. When discharging, the second switch needs to be turned on and the first switch needs to be turned off to perform discharging. In this way, the number of wiring operations is reduced, and the workload during wiring is decreased.

[0013] Furthermore, the first switch and the second switch can be turned on simultaneously, and the information processing module simultaneously transmits the storage battery voltage to the inspection instrument module and the discharge instrument module.

[0014] In the technical solution provided by this application, the voltage acquisition device can communicate with the inspection instrument module and the discharge instrument module simultaneously by setting two switches, avoiding the situation that the user needs to connect the storage battery to the voltage acquisition device matching the discharge instrument during the discharge experiment, and then needs to connect the storage battery to the voltage acquisition device matching the inspection instrument during normal operation. The number of wiring operations by the user is reduced, the workload of wiring is decreased, and the safety of the storage battery system is improved.

[0015] Furthermore, the positive electrode connecting wire is provided with a red coating.

[0016] Furthermore, the negative electrode connecting wire is provided with a black coating.

[0017] In this solution, by setting the middle parts of the positive electrode connecting wire and the negative electrode connecting wire to be red and black respectively, the positive electrode connecting wire and the negative electrode connecting wire can be distinguished quickly.

[0018] Since there are many groups of storage batteries, it is difficult to distinguish them when multiple groups of connecting wires are used. To solve this problem, this application provides the following technical solution:

[0019] Furthermore, a plurality of color identification positions are provided on both the positive electrode connecting wire and the negative electrode connecting wire. The color identification positions are located in the vicinity of the ends of the positive electrode connecting wire and the negative electrode connecting wire.

[0020] Furthermore, the positive electrode connecting wire and the negative electrode connecting wire of the same group have the same color at each color identification position. By numbering the connecting wires through the color identification positions, the identification efficiency of the operator is improved.

[0021] To prevent the user from misreading the order of the color identifications, the width of the first color identification position is twice that of the widths of the remaining color identifications.

[0022] Furthermore, the connection ends of the positive electrode connecting wire and the negative electrode connecting wire are provided with a background color layer, the background color layer is white, and the color identification positions are annular color layers coated on the background color layer.

[0023] In the technical solution provided by this application, by setting a number of color identification positions on the positive connection line and the negative connection line, it is possible to use different color combinations to identify each connection line, avoiding the problem that it is difficult to identify the connection lines due to the large number of connection lines.

[0036] Embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not used to limit the protection scope of the present application.

[0037] In addition, it should be noted that for ease of description, only parts related to the relevant invention are shown in the drawings. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0038] The present application will be described in detail below with reference to the drawings and in combination with embodiments.

[0039] Embodiment 1: Referring to Figure 1 , a voltage acquisition device applicable to a battery inspection instrument and a discharge instrument includes an information processing module 1, a positive connection line 3, and a negative connection line 4. Among them, the information processing module 1 is provided with a plurality of positive input terminals and negative input terminals corresponding to the positive input terminals.

[0040] The information processing module 1 is internally provided with a plurality of connection detection units, each connection detection unit has a corresponding positive input terminal and negative input terminal, and the positive input terminal and negative input terminal of each connection detection unit are a group.

[0041] The information processing module 1 is provided with a first switch and a second switch, and both the first switch and the second switch are connected to each detection unit. Furthermore, the inspection instrument is connected to the first switch, and the discharge instrument is connected to the second switch. When the first switch is closed, the inspection instrument can detect the voltage of the battery connected to the information processing module 1. When the second switch is closed, the discharge instrument can detect the voltage of the battery connected to the information processing module 1. Among them, the discharge instrument detects the voltage during discharge, and the inspection instrument detects the voltage during operation.

[0042] Furthermore, the first switch and the second switch can be opened simultaneously, and the information processing module simultaneously transmits the battery voltage to the inspection instrument module and the discharge instrument module.

[0043] Each connection detection unit in the information processing module 1 is equivalent to a controllable logic switch. When it is necessary to connect the battery to the discharge instrument or the inspection instrument, the corresponding connection detection unit is closed, and then the battery is connected to the corresponding discharge instrument or inspection instrument. The specific circuit structure in the information processing module 1 is also the prior art, and further explanation is not required when its specific function is known.

[0044] The positive connection line 3 and the negative connection line 4 are used to connect the information processing module 1 and the battery 2 to be measured. Among them, one end of the positive connection line 3 is fixedly connected to the positive input terminal, and the other end is connected to the positive electrode 21 of the battery 2. Multiple positive connection lines 3 are provided. The negative connection line 4 is provided with multiple ones. One end of the negative connection line 4 is fixedly connected to the negative input terminal, and the other end is connected to the negative electrode 22 of the battery 2. Thus, by adopting the technical solution provided by this application, the voltages of multiple batteries 2 can be measured at one time.

[0045] Reference Figure 2 , Further, the connection end of the positive connection line 3 is provided with a positive connector 31 with the same structure, and the connection end of the negative connection line 4 is provided with a negative connector 41 with the same structure; the said connection end is the end where the positive connection line 3 and the negative connection line 4 need to be connected to the battery. Among them, the positive connector 31 and the negative connector 41 are respectively the connection heads of the connection ends of the positive connection line 3 and the negative connection line 4, playing a role in connection. In this solution, the positive connector 31 and the negative connector 41 are two different-shaped structures, so the positive connector 31 can be connected to the positive electrode 21 of the battery 2 and cannot be connected to the negative connector 41. Conversely, the negative connector 41 cannot be connected to the positive electrode 21 of the battery 2 either. Based on this, this application provides the following solution:

[0046] Reference Figure 3 , Embodiment 1: The positive connection line 3 and the positive electrode of the battery 2 are in plug-in connection, and the negative connection line 4 and the negative electrode of the battery 2 are in plug-in connection. The positive electrode 21 of the battery is constructed as a columnar structure, and the conductive surface of the positive electrode 21 of the battery is arranged on the outer side of the columnar structure. The negative electrode 22 of the battery is constructed as a jack, and the conductive surface of the negative electrode 22 of the battery is arranged on the inner wall of the jack.

[0047] Specifically, the positive electrode 21 of the battery includes a fixed column 211, and the outer side surface of the fixed column 211 is the conductive surface. Correspondingly, the positive connector 31 is constructed as a cylindrical structure, the inner diameter of the positive connector 31 is adapted to the outer diameter of the fixed column 111, and the inner wall of the positive connector 31 is provided with a conductive surface. Therefore, when the positive connector 31 is sleeved on the positive electrode 21 of the battery, the two are electrically connected.

[0048] Correspondingly, the negative electrode 22 of the storage battery includes a fixed cylinder 221. An insertion hole 2211 with an open upper end is provided on the fixed cylinder 221. The cross-section of the insertion hole is circular, and a conductive surface is provided on the inner wall of the insertion hole. The negative connector 41 includes a connecting portion 411 and a blocking portion 412. Among them, the connecting portion 411 is a columnar structure, the blocking portion 412 is arranged at the end of the connecting portion 411, the blocking portion 412 is an annular structure, the outer diameter of the connecting portion 411 is the same as the inner diameter of the insertion hole, the first end of the connecting portion 411 is inserted into the insertion hole, and the outer diameter of the blocking portion 412 is larger than the outer diameter of the connecting portion 411. The outer wall of the connecting portion 411 and the inner wall of the insertion hole are both conductive surfaces, so that after the two are plugged, electrical connection can be achieved.

[0049] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that the positive electrode 21 of the storage battery and the positive electrode connecting wire 3 are in threaded connection, and the negative electrode 22 of the storage battery and the negative electrode connecting wire 4 are in threaded connection. In this way, on the basis of Embodiment 1, threads are provided on the outer wall of the positive electrode 21 of the storage battery, that is, threads are provided on the outer wall of the fixed column 211. Correspondingly, threads are also provided on the inner wall of the cylindrical structure of the positive connector 31. Furthermore, the positive electrode 21 of the storage battery and the positive connector 31 can be connected by threads. Threads are provided on the inner wall of the insertion hole, and threads are also provided on the outer wall of the connecting portion 411. Therefore, the negative electrode 22 of the storage battery and the negative electrode connecting wire 4 can be connected by threads.

[0050] Reference Figures 3 to 4 , Example 2: The difference between Example 2 and Example 1 lies in the color difference between the positive electrode connecting wire and the negative electrode connecting wire.

[0051] The positive electrode connecting wire 3 is provided with a red coating 3a, and the negative electrode connecting wire 4 is provided with a black coating 4a. In this way, in a positive electrode connecting wire 3, the surface of the outer insulating part of the positive electrode connecting wire 3 is red, which can facilitate the distinction between the positive electrode connecting wire and the negative electrode connecting wire.

[0052] Example 3: The difference between Example 3 and Example 2 is that when the number of storage batteries is too large, a plurality of color identification positions 1b are provided on the positive electrode connecting wire 3 and the negative electrode connecting wire 4 to distinguish different groups of positive electrode connecting wires 3 and negative electrode connecting wires 4.

[0053] Furthermore, a plurality of color identification positions 1b are provided on both the positive electrode connecting wire 3 and the negative electrode connecting wire 4. The color identification positions 1b are arranged on one side of the connection ends of the positive electrode connecting wire and the negative electrode connecting wire, near the connection ends; the colors of the positive electrode connecting wire and the negative electrode connecting wire in the same group are the same at each color identification position.

[0054] Specifically, a plurality of annular color representation bits 1b are provided at the ends of the positive connection line and the negative connection line to identify the serial numbers of the respective positive connection lines and negative connection lines. For example, the colors orange, orange-yellow, yellow, yellow-green, green, blue-green, blue, purple, purple-red, and blue-violet are selected to represent 0 to 9 respectively. If it is necessary to represent the positive connection line with a value of 101, it is only necessary to apply orange-yellow, orange, and orange-yellow on the 3 color representation bits of the positive connection line respectively.

[0055] To prevent users from misreading the order of the color identifications, the width of the first color identification bit 1b is 2 times that of the remaining color identifications. In practice, it can also be set to 3 times or 1.5 times. It is only necessary that there is an obvious difference between the width of the first color identification bit 1b and the width of the remaining color identification bits.

[0056] Example 4: The difference between Example 4 and Example 3 is that in the solution of Example 4, a corresponding background color is set to facilitate the distinction of the color identification bits.

[0057] Specifically, a background color layer 1a is provided at the connection terminals of the positive connection line 3 and the negative connection line 4. The background color layer 1a is white, and the color identification bit is an annular color layer coated on the background color layer. The background color layer 1a is located at the end position of the positive connection line 3 or the negative connection line 4, and the covering position of the background color layer 1a is the annular color layer.

[0058] The above description is only some preferred embodiments of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the embodiments of the present application.
