Abstract
Description
Technical Field
[0001] This application relates to the field of power switchboard technology, and in particular to a high-voltage load switchboard. Background Technology
[0002] A high-voltage load cell is a device used to test and simulate high-voltage power supply loads, enabling the testing of the power supply's performance and stability. By simulating various high-voltage load conditions, the load cell helps evaluate the output capability and stability of the high-voltage power supply under different loads, and tests various performance parameters, such as voltage, current, and power factor.
[0003] The common installation method for high-voltage load switchgear is as follows: First, multiple series resistors are fixed to insulating brackets. Then, the insulating brackets for mounting the resistors are installed inside an epoxy material enclosure. This completes the construction of the high-voltage load switchgear.
[0004] To meet the R&D needs of different high-voltage power supply models, high-voltage load cabinets with varying resistance values are required. However, due to the large size of these load cabinets and the opaque casings of commercially available products, traditional high-voltage load cabinets suffer from problems such as non-adjustable resistance values and the inability to directly observe current changes.
[0005] There is currently no effective solution to the technical problems existing in the prior art, namely that the resistance of the high-voltage load cabinet cannot be adjusted and the current change of the high-voltage load cabinet cannot be directly observed. Utility Model Content
[0006] This invention provides a high-voltage load cabinet to at least solve the technical problems existing in the prior art, such as the inability to adjust the resistance value of the high-voltage load cabinet and the inability to directly observe the current changes of the high-voltage load cabinet.
[0007] According to one aspect of this application, a high-voltage load cabinet is provided, comprising: a cabinet body, a plurality of resistor components, and an ammeter, wherein the plurality of resistor components are disposed inside the cabinet body; the resistor components include a plurality of adjustment components, and the series or parallel connection relationship between the resistor components is changed through the plurality of adjustment components; and the plurality of resistor components are connected in series with the ammeter, and the ammeter displays the current value corresponding to the plurality of resistor components.
[0008] Optionally, the cabinet body can be made of acrylic sheet.
[0009] Optionally, the resistor assembly further includes: a resistor, and a plurality of adjustment components including: a first adjustment component and a second adjustment component, wherein the first adjustment component is mounted on a first end of the resistor, and the second adjustment component is mounted on a second end of the resistor.
[0010] Optionally, the adjustment component includes: a banana plug and a terminal block, wherein the banana plug is connected to the terminal block; and the terminal block is connected to a resistor.
[0011] Optionally, the resistor assembly also includes a resistor bracket, and the cabinet body has a support plate arranged at preset intervals inside, wherein the resistor is mounted on the resistor bracket; and the resistor bracket is arranged on the support plate at preset intervals.
[0012] Optionally, multiple casters are installed on the bottom outer side of the cabinet body.
[0013] Optionally, the cabinet body includes: a cabinet body and a cabinet door, wherein one side of the cabinet door is rotatably connected to the cabinet body.
[0014] This application provides a high-voltage load cabinet. Because the high-voltage load cabinet of this application contains multiple resistor components, and each resistor component includes multiple adjustment components, the series or parallel connection relationship between the resistor components can be changed through these adjustment components. That is, by changing the connection relationship between the multiple adjustment components in each resistor component, the resistor components can be changed from a series connection to a parallel connection, or vice versa. This achieves the technical effect of changing the resistance value of the high-voltage load cabinet.
[0015] Furthermore, since an ammeter is installed inside the high-voltage load cabinet, and multiple resistor components are connected in series with the ammeter, the ammeter can display the current value corresponding to each resistor component. That is, regardless of whether the resistor components inside the high-voltage load cabinet are connected in series or parallel, the ammeter will display the corresponding current value. This allows operators to directly observe the current changes in the high-voltage load cabinet through the ammeter.
[0016] This solves the technical problems existing in the technology where the resistance of the high-voltage load cabinet is not adjustable and the current change of the high-voltage load cabinet cannot be directly observed.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0026] Figure 1 This is a three-dimensional structural diagram of the high-voltage load cabinet according to the embodiments of this application. Figure 2 This is a front view of the high-voltage load cabinet according to an embodiment of this application. (Reference) Figure 1 and Figure 2As shown, a high-voltage load cabinet includes: a cabinet body 10, multiple resistor assemblies 20, and an ammeter 30, wherein the multiple resistor assemblies 20 are disposed inside the cabinet body 10; each resistor assembly 20 includes multiple adjusting components 210, and the series or parallel connection relationship between the resistor assemblies 20 is changed through the multiple adjusting components 210; and
[0027] Multiple resistor components 20 are connected in series with an ammeter 30, and the current value corresponding to the multiple resistor components 20 is displayed.
[0028] As described in the background section, the common installation method for high-voltage load switchgear is as follows: First, multiple series resistors are fixed to insulating brackets. Then, the insulating brackets for mounting the resistors are installed inside an epoxy-coated enclosure. This ultimately constructs the high-voltage load switchgear.
[0029] To meet the R&D needs of different high-voltage power supply models, high-voltage load cabinets with varying resistance values are required. Furthermore, these high-voltage load cabinets are quite bulky, and the casings of commercially available load cabinets are typically opaque. Consequently, traditional high-voltage load cabinets suffer from problems such as non-adjustable resistance values and the inability to directly observe current changes.
[0030] In view of this, this application provides a high-voltage load cabinet. The high-voltage load cabinet includes a cabinet body 10, multiple resistor components 20, and an ammeter 30. The multiple resistor components 20 are disposed inside the cabinet body 10, and each resistor component 20 includes multiple adjustment components 210. The adjustment components 20 are used to adjust the series and parallel connections between the resistor components 20. That is, by changing the connection relationship between the adjustment components 210 of each resistor component 20, the resistor components 20 can be changed from a series connection to a parallel connection, or vice versa. Therefore, since the high-voltage load cabinet of this embodiment can change the resistance value, it can simulate high-voltage load conditions and help evaluate the output capability and stability of the high-voltage power supply under different loads.
[0031] Furthermore, since multiple resistor components 20 are connected in series with the ammeter 30, the ammeter 30 will display the corresponding current value regardless of whether the resistor components 20 are connected in series or in parallel. Thus, the operator can assess the current changes of the high-voltage power supply by using the current value displayed by the ammeter 30.
[0032] Furthermore, since the ammeter 30 can display the current changes corresponding to the multiple resistor components 20, the operator can calculate the actual voltage and power of the high-voltage power supply based on the values displayed by the ammeter 30 and the resistance values corresponding to the multiple resistor components 20. This allows the operator to adjust the series and parallel connections between the various resistor components 20 according to the current values displayed by the ammeter 30.
[0033] This solves the technical problems existing in the prior art, such as the inability to adjust the resistance of the load cabinet and the inability to directly observe the current changes of the high-voltage power supply load.
[0034] Optionally, the cabinet body 10 is made of acrylic sheet. Because acrylic sheet is transparent, operators can observe the changes in current value of the ammeter 30 inside the cabinet body 10, as well as the ignition point. This achieves the technical effect of facilitating operator observation of the ignition point and current value changes.
[0035] Optionally, the resistor assembly 20 further includes a resistor 220, and a plurality of adjustment assemblies 210 including a first adjustment assembly 211 and a second adjustment assembly 212, wherein the first adjustment assembly 211 is mounted on a first end of the resistor 220, and the second adjustment assembly 212 is mounted on a second end of the resistor 220.
[0036] Specifically, Figure 3 This is a schematic diagram of the resistor assembly according to an embodiment of this application. (Reference) Figure 3 As shown, the resistor assembly 20 includes a resistor 220, and a first adjustment component 211 and a second adjustment component 212 are respectively provided at both ends of the resistor 220. Thus, by changing the connection relationship between the first adjustment component 211 and the second adjustment component 212 between two adjacent resistor assemblies 20, the connection relationship (i.e., series-parallel relationship) between each resistor assembly 20 can be changed.
[0037] Optionally, the adjustment assembly 210 includes: a banana plug 213 and a terminal block 214, wherein the banana plug 213 is connected to the terminal block 214; and the terminal block 214 is connected to the resistor 220.
[0038] Specifically, refer to Figure 3 As shown, the plurality of adjustment components 210 include a first adjustment component 211 and a second adjustment component 212. Both the first adjustment component 211 and the second adjustment component 212 include a banana plug 213 and a terminal block 214. The banana plug 213 is electrically connected to the terminal block 214. The terminal block 214 is electrically connected to a resistor 220.
[0039] Therefore, the embodiments of this application can adjust the resistance values of multiple resistor components 20 through a reliable plug jumper, thereby simulating different types of high-voltage power supplies and contributing to the development of different types of high-voltage power supplies.
[0040] Optionally, the resistor assembly 20 also includes a resistor bracket 230, and a support plate 110 is provided inside the cabinet body 10 at preset intervals, wherein the resistor 220 is mounted on the resistor bracket 230; and the resistor bracket 230 is provided on the support plate 110 at preset intervals.
[0041] Specifically, refer to Figure 1 , Figure 2 and Figure 3 As shown, the resistor assembly 20 includes a resistor bracket 230, and the resistor 220 is mounted on the resistor bracket 230. Furthermore, the cabinet body 10 has support plates 110 arranged at preset intervals inside, and the resistor brackets 230 are sequentially arranged on the support plates 110.
[0042] Therefore, since the high-voltage load cabinet in this embodiment adopts a vertically arranged multi-layer structure, with 6 to 7 resistor supports 230 arranged on each layer, and a high-power high-voltage resistor 220 installed on each resistor support 230, it can achieve the technical effect of installing multiple resistors 220 and improving the application range of the high-voltage load cabinet.
[0043] Optionally, multiple casters 40 are installed on the outer bottom of the cabinet body 10. This achieves the technical effect of facilitating the movement of the high-voltage load cabinet by operators and eliminating the positional limitations of the high-voltage load cabinet. Further optionally, the cabinet body 10 includes a cabinet 120 and a cabinet door 130, wherein one side of the cabinet door 130 is rotatably connected to the cabinet body 120.
[0044] Because the high-voltage load cabinet in this application contains multiple resistor components, and each resistor component includes multiple adjustment components, the series or parallel connection relationship between the resistor components can be changed through these adjustment components. That is, by changing the connection relationship between the multiple adjustment components in each resistor component, the resistor components can be changed from a series connection to a parallel connection, or vice versa. This achieves the technical effect of changing the resistance value of the high-voltage load cabinet.
[0045] Furthermore, since an ammeter is installed inside the high-voltage load cabinet, and multiple resistor components are connected in series with the ammeter, the ammeter can display the current value corresponding to each resistor component. That is, regardless of whether the resistor components inside the high-voltage load cabinet are connected in series or parallel, the ammeter will display the corresponding current value. This allows operators to directly observe the current changes of the high-voltage power supply through the ammeter.
