Description

Technical Field

[0001] This utility model relates to an energy storage power analysis and testing cabinet, and more particularly to a dual-row protected energy storage power analysis and testing cabinet. Background Technology

[0002] Current energy storage testing generally uses a two-battery-compartment towing test method, with the two battery compartments connected to a test cabinet. Due to the large size of the battery compartments, transportation is inconvenient. In order to meet the versatility of the cables, it is often necessary to reserve a long cable from the battery compartment to the test cabinet. Cable wiring is quite difficult, and long-distance cable layout affects the turnover of other products and electrical safety.

[0003] As the capacity of energy storage products in the market increases, the system voltage also rises. The PCS (Power Conversion System) used for testing, i.e. the energy storage converter, will generate short-term peak harmonic voltage during the initial startup. When the peak harmonic voltage exceeds a certain value, it will cause the surge protector to trip or even explode, and in severe cases, it will cause short circuits in electrical components.

[0004] Existing test cabinets and their systems typically read voltage and current parameters through a BMS (Battery Management System) to calculate parameters such as power and efficiency. However, BMS accumulates and calculates data for each cluster and has low sampling accuracy, often resulting in inaccurate data. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a dual-row protected energy storage power analysis and testing cabinet.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a double-row protective energy storage power analysis test cabinet, including a first test cabinet and a second test cabinet arranged in pairs. Each of the first and second test cabinets is equipped with a Hall sensor, a positive copper busbar connected to the Hall sensor, a positive cable connected to the positive copper busbar, a negative copper busbar, a negative cable connected to the negative copper busbar, and an auxiliary power switch.

[0007] A power analyzer is installed inside the first test cabinet;

[0008] The second test cabinet is equipped with a switching power supply.

[0009] Furthermore, both the first and second test cabinets are vertical structures;

[0010] The first test cabinet is divided into an upper partition and a lower partition.

[0011] The second test cabinet is divided into upper and lower sections, with an upper section for the second test cabinet and a lower section for the second test cabinet.

[0012] Furthermore, the auxiliary power switch and power analyzer of the first test cabinet are installed in the interval on the first test cabinet.

[0013] Furthermore, the Hall sensor, positive copper busbar, positive cable, negative copper busbar, and negative cable of the first test cabinet are installed in the lower compartment of the first test cabinet.

[0014] Furthermore, the auxiliary power switch and switching power supply of the second test cabinet are located within the interval on the second test cabinet.

[0015] Furthermore, the Hall sensor, positive copper busbar, positive cable, negative copper busbar, and negative cable of the second test cabinet are installed in the lower compartment of the second test cabinet.

[0016] Furthermore, the positive copper busbar runs through the Hall sensor from top to bottom.

[0017] Furthermore, the negative cable is connected to the lower end of the negative copper busbar.

[0018] A dual-row protected energy storage power analysis and testing cabinet has the following advantages:

[0019] 1. The design adopts a dual-row configuration, which means that two separate test cabinets are used. Each test cabinet can be transported to a suitable location around each battery compartment, allowing for flexible arrangement, reducing the length of the main cable, and optimizing the layout to minimize the impact on the turnover of other products and electrical safety.

[0020] 2. It can detect the system voltage. When the voltage exceeds the set threshold and continues for a certain period of time, the power analyzer in the test cabinet outputs a signal, the main circuit breaker disconnects, and the electrical system is safe.

[0021] 3. Employing a large-range Hall sensor in conjunction with a multi-functional power analyzer ensures measurement accuracy. It can accurately measure voltage, current, and power parameters of multi-phase voltage and current, and supports sampling waveform display, spectrum analysis, and harmonic flicker analysis functions.

[0028] The first test cabinet 1 forms an upper partition 11 and a lower partition 12 of the first test cabinet, which are divided into upper and lower sections; the second test cabinet 2 forms an upper partition 13 and a lower partition 14 of the second test cabinet, which are divided into upper and lower sections.

[0029] Preferably, the auxiliary power switch 9 and the power analyzer 3 of the first test cabinet 1 are arranged within a space 11 on the first test cabinet.

[0030] Furthermore, the Hall sensor 4, positive copper busbar 5, positive cable 6, negative copper busbar 7, and negative cable 8 of the first test cabinet 1 are arranged in the lower interval 12 of the first test cabinet.

The power analyzer 3 can accurately measure voltage parameters, current parameters, and power parameters, including voltage and current. It also supports functions including sampling waveform display, spectrum analysis, and harmonic flicker analysis.

[0038] The switching power supply 10 is used to provide low-voltage DC power to the power analyzer 3, and the auxiliary power switch 9 is used to control the switching power supply 10 to switch on and off.
