Description

Technical Field

[0001] This utility model relates to the field of power, and in particular to a testing device for high and low temperature experiments on data acquisition terminals. Background Technology

[0002] During high and low temperature experiments, it is necessary to verify the data acquisition terminal's accuracy, uplink and downlink communication testing, status data acquisition, control output, and data collection functions. Setting up the experimental environment is complex; the data acquisition terminal inside the temperature chamber needs to be connected to external standard source platforms, pulse generators, loop detectors, meters, and other auxiliary testing equipment. Currently, multiple data acquisition terminals need to be tested simultaneously, connected via terminal blocks using screw crimping. This results in a large number of wires, many of which are intertwined, easily confusing different types of wires. This leads to low efficiency in reassembling and disconnecting the wires for each experiment and easily damages the contact points, causing poor contact and requiring frequent maintenance. Furthermore, setting up and disassembling the experimental environment requires constantly tightening and loosening screws with a screwdriver, and the exposed terminals pose a risk of accidental electric shock. In the power industry, to strengthen meter management, comprehensive high and low temperature experiments are necessary for the data acquisition terminals to ensure their adaptability, tolerance, accuracy, and stability under harsh temperature conditions meet application requirements. Currently, the lack of dedicated testing equipment during high and low temperature experiments causes inconvenience for the inspection of the data acquisition terminals. Currently, when manually verifying the functionality of high and low temperature data acquisition terminals, it is necessary to manually connect a large number of cables to auxiliary testing equipment such as standard source platforms. This process is inefficient, dangerous, and prone to errors.

[0003] In order to solve the above-mentioned technical problems, this utility model designs a testing device for high and low temperature experiments on data acquisition terminals. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and examples:

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1 and Figure 2As shown, a testing device for high and low temperature experiments on a data acquisition terminal is characterized by: a conversion device for high-voltage and low-voltage terminals of a platform, a conversion device for high-voltage and low-voltage terminals of a data acquisition terminal, and a connecting cable. Both ends of the connecting cable are provided with banana-shaped connectors. The conversion device for the high-voltage and low-voltage terminals of the platform includes a platform 1 and a platform conversion device 3 mounted on the platform 1. The platform conversion device 3 is provided with a platform conversion terminal 2. The conversion device for the low-voltage terminals includes a terminal fixing plate 6 and a terminal conversion device 8. A fixing base 5 is fixedly connected to the terminal fixing plate 6, and the fixing base 5 is used to fix the data acquisition terminal. The terminal conversion device 8 is provided with a data acquisition terminal conversion terminal 9. One end of the connecting cable is connected to the platform conversion terminal 2 via a banana-shaped connector, and the other end is connected to the conversion terminal 9 via a banana-shaped connector.

[0022] The banana-shaped connector is used to connect the platform 1 and the data acquisition terminal inside the incubator. The banana-shaped connector allows operators to quickly connect and disconnect the wires to and from the platform adapter terminal 2 and the data acquisition terminal adapter terminal 9 without the need for tools such as screwdrivers, improving the efficiency of experimental setup and disassembly. Traditional screw-on methods can easily lead to crossover and confusion of different types of wires, while using a banana-shaped connector ensures that each wire is correctly connected to its corresponding terminal, reducing the possibility of incorrect connections. Since frequent tightening and loosening of screws is not required, the risk of accidental electric shock due to exposed terminals is avoided, enhancing operational safety. Each plugging and unplugging does not damage the contact points, thus reducing the probability of connection damage and lowering long-term maintenance costs.

[0023] The platform 1 is connected to the copper post of the platform adapter 3 via an electrical probe 4 on the platform, and the electrical probe 7 on the terminal of the acquisition terminal is connected to the copper post of the adapter terminal 9. The connection between the copper post and the electrical probe provides a low-resistance conductive path, ensuring stable current transmission. This connection method can guarantee the quality of signal transmission and reduce signal loss or noise caused by poor contact. Compared with the traditional screw crimping method, the method of inserting the electrical probe into the copper post is more stable and less prone to loosening due to vibration or slight movement, thereby reducing maintenance needs and lowering the risk of data errors caused by unstable connection.

[0024] The platform adapter terminals 2 are arranged in two rows, with the upper row for high-voltage power supply terminals and the lower row for low-voltage control terminals. The high-voltage power supply terminals include voltage terminals 2-UA, 5-UB, 8-UC, and 10-UN, and current terminals 1-Ia+, 3-Ia-, 4-Ib+, 6-Ib-, 7-Ic+, and 9-Ic-. The low-voltage control terminals include 13~20-closing terminals 1~4, 21~22-door contacts, and pulse outputs: 23-positive active power, 24-positive reactive power, 25-second pulse, 26-COM, 27-CAN-H / RS485Ⅱ-A, 28-CAN-L / RS485Ⅱ-B, 29-RS485Ⅰ-A, and 30-RS485Ⅰ-B.

[0025] The adapter terminal 9 consists of two rows: the upper row is for low-voltage control terminals, and the lower row is for high-voltage power supply terminals. The low-voltage control terminals include 13~20 (closing 1~4), 21~22 (door contacts), and pulse outputs: 23 (positive active power), 24 (positive reactive power), 25 (second pulse), 26 (COM), 27 (CAN-H / RS485Ⅱ-A), 28 (CAN-L / RS485Ⅱ-B), 29 (RS485Ⅰ-A), and 30 (RS485Ⅰ-B). The lower row of high-voltage power supply terminals includes voltage terminals 2-UA, 5-UB, 8-UC, and 10-UN, and current terminals 1-Ia+, 3-Ia-, 4-Ib+, 6-Ib-, 7-Ic+, and 9-Ic-.

[0026] The low-voltage control terminals and the high-voltage power supply terminals are on different planes, such as... Figure 4 As shown.

[0027] Low-voltage control terminals require longer leads or connectors to accommodate different connection needs, such as connecting to thin wires or providing better contact stability. These terminals are designed with longer leads or pins to ensure reliable electrical connections under various conditions. In contrast, high-voltage power supply terminals do not require such long leads because they are primarily used to connect thicker power lines. These thicker wires have better mechanical strength, so the length requirement for the terminals is not high. Furthermore, to reduce space occupation and avoid unnecessary exposure, high-voltage terminals are often designed to be more compact, i.e., relatively short.

[0028] The reason why the strong and weak terminals of adapter terminal 9 and adapter terminal 2 are opposite is that when the power pin 7 on the terminal is connected to the copper post of adapter terminal 9, the long and short pins of the power pin 7 need to be connected to the weak current control terminal and the strong current power supply terminal respectively. If the weak current control terminal is longer and is located below, it will block the strong current power supply terminal and cause interference.

[0029] Traditional wiring methods involve screwing screws onto each wire terminal individually, resulting in messy wiring. To solve this problem, all terminals of the terminal need to be brought out and then connected to the test device via banana plugs.

[0030] like Figure 3 As shown, the device also includes a converter for the auxiliary terminal of the acquisition terminal connected to the terminal converter 8. The converter for the auxiliary terminal of the acquisition terminal includes a green terminal converter 10 for the left module of the acquisition terminal and a green terminal converter 11 for the right module of the acquisition terminal.

[0031] The left module green terminal adapter 10 of the acquisition terminal is provided with a left module adapter terminal, and the left module green terminal adapter 10 is connected to the terminal upper electrode 7 and the left module adapter terminal through an internal copper post; the right module green terminal adapter 11 of the acquisition terminal is provided with a right module adapter terminal, and the right module adapter 11 is connected to the terminal upper electrode 7 and the right module adapter terminal through an internal copper post.

[0032] The left module adapter terminals include 31~38 - trip 1~trip 4, 39~40 - alarm, which can be led out through a connecting cable with a banana terminal according to the test requirements.

[0033] The right module adapter terminals include pulse inputs: 41~42 - Pulse 1, 43~44 - Pulse, and remote signaling inputs: 45 - YX1, 46 - YX2, 47 - YXG, 48 - YX3, 49 - YX4, 50 - YXG, which can be led out through connecting cables with banana terminals according to testing requirements.

[0034] Both the left and right module adapter terminals are equipped with lead wires. Banana connectors are provided at both ends of the lead wires.

[0035] By pre-leading out all terminals of the acquisition terminal, connections can be made directly using quick connectors such as banana plugs, eliminating the need to reconnect wires or tighten screws for each experiment. This significantly improves the speed of experiment preparation and disassembly.

[0036] The terminal adapter 8 is equipped with a slide rail, on which the green terminal adapter 10 for the left module of the acquisition terminal and the green terminal adapter 11 for the right module of the acquisition terminal are slidably connected. When testing is not required, the adapters for the auxiliary terminals of the acquisition terminal can be removed.

[0037] Alternatively, the adapter for the auxiliary terminal of the acquisition terminal is snapped onto the terminal adapter 8.

[0038] like Figure 4 As shown, the height of the adapter terminal 9 is less than the height of the adapter device of the data acquisition terminal auxiliary terminal. Figure 4This is a schematic diagram showing the data acquisition terminal fixed on the mounting base 5.

[0039] When wiring, first connect adapter terminal 9, then connect the green terminal adapter 10 on the left module of the acquisition terminal and the green terminal adapter 11 on the right module of the acquisition terminal. The two rows of terminals are not on the same plane, preventing the wires from becoming tangled and facilitating plugging and unplugging. By arranging different types of terminals in layers, the connecting wires do not become tangled or cross each other, maintaining a neat and orderly wiring. This is not only aesthetically pleasing, but more importantly, it reduces the risk of incorrect connections caused by messy cables.

[0040] The connection between the data acquisition terminal and the standard source platform is achieved through adapters connecting the high-voltage and low-voltage terminals of the platform and the data acquisition terminal. Depending on the testing requirements, after extending the data acquisition terminal using an adapter connected to the auxiliary terminals, it can be connected to auxiliary testing equipment such as pulse generators, loop detectors, and meters for testing.

[0041] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
