1756-A7 Seven slot chassis

Physical structure:
Size: The physical size is 50.8×60.9×20.3 centimeters (20x24x8 inches), which is a relatively compact chassis that is easy to install and use in various space limited environments.
Weight: Approximately 1.10 kilograms (2.4 pounds), relatively lightweight, easy to handle and install.
Installation method: Install directly onto the sub panel of the cabinet using the four provided mounting tabs, with two mounting tabs at the top and two at the bottom. If SEM screws are not installed, in addition to two flat washers and two locking washers, two star washers are also required; If used together with SEM screws, only two cross screws are required.
Shell: Open shell, convenient for users to install and maintain internal modules, but also means it does not have an additional protective shell.
Power related:
Power slot: equipped with a power installation slot, located on the leftmost side of the chassis, supporting the installation of ultra-thin, standard, and power modules.
Power consumption: The power consumption is 4.5 watts, and in terms of backplane current supply, it can provide 1.5A@1.2Vdc The 4A@3.3Vdc The chassis/slot is 15A/ 6A@5.1Vdc And 2.8A/ 2.8A@24Vdc The current.
Work environment:
Temperature: The working temperature range is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit), and it is recommended to store within a temperature range of -40 to 85 degrees Celsius to adapt to a wide range of temperature environments. However, in practical applications, it should be ensured that it operates within the appropriate temperature range to ensure performance and stability.
Humidity: The compatible humidity type is non condensing, and the relative humidity level that the chassis can use is 5% to 95%, with good humidity resistance. However, it is still important to avoid prolonged use in high humidity environments where condensation may occur.
Impact level: The impact level of the chassis in working condition is 30g (acceleration), and in non working condition, the impact level is 50g (acceleration). It has a certain impact resistance and can work stably in some industrial environments with certain vibrations and impacts.
Grounding setting:
Equipped with functional grounding and protective grounding terminals. The recommended wire type and size for functional grounding is 8.3 square millimeters (8AWG) solid copper wire or stranded copper wire, with an insulation level of 90 ° C (194 ° F) or higher; For protective grounding terminals, the appropriate wire size is 2.1 square millimeters (14AWG) solid or stranded copper wire with an insulation level of 90 ° C (194 ° F) or higher.
The 1756-A7 chassis, as an important component of the ControlLogix Programmable Automation Controller (PAC) platform, provides backplane connections and installation space for various modules, and is widely used in industrial automation fields such as manufacturing, energy, and transportation. In practical applications, users can install corresponding modules on their slots according to specific control requirements, and build control systems that meet specific functional requirements.

As a pioneer in technology, ABB has received an order from Transpower New Zealand to upgrade its high-voltage direct current (HVDC) transmission lines, which interconnect the transmission networks of the North and South Islands.

It is reported that this high-voltage direct current transmission line connecting the North Island and South Island of New Zealand is an important component of the country’s power grid system and also the power balance system between South Africa. ABB’s Ability MACH control system, as the brain or nerve center of the link, will become a key component of the upgrade.

It is reported that the population of the North Island of New Zealand is more than three times that of the South Island, and in addition to its picturesque scenery, it also provides a large amount of hydroelectric power. Therefore, the demand for electricity in the North Island has greatly increased and relies on the power supply in the South Island. The north-south high-voltage direct current transmission interconnection line, which is over 600 kilometers long, can efficiently transmit clean electricity to high demand areas. The line also plays an important role in the New Zealand electricity market by allowing electricity trading between two islands.

ABB has a historic involvement in this project. The first New Zealand HVDC transmission system was built by ABB (formerly ASEA) in 1965, which was also one of the world’s first HVDC transmission systems at that time. It was originally a bipolar 600 megawatt (MW) link with a mercury arc valve, until 1992 when the original equipment was connected in parallel to a single pole and ABB collaborated with it to debug a new thyristor pole, increasing the capacity to 1040 MW.

It is reported that this upgrade includes the upgrade of Valve 2, which is composed of electrodes, optical fibers, and valve control units based on the latest ABB Ability MACH control system. The upgrade will be completed in 2020, and its implementation will minimize the impact on the power grid and electricity trading market.

This upgrade will improve the reliability and availability of the power grid, thereby enhancing power safety and bringing clean energy to consumers, “said Claudio Facchin, President of ABB’s Power Grid Division.” This project reaffirms our strategic focus on services and commitment to integrating renewable energy, as well as the role of digital technology based on ABB’s capabilities, and consolidates our leading position in HVDC technology, becoming the preferred partner for achieving a stronger, smarter, and more environmentally friendly power grid

ABB pioneered high-voltage direct current transmission technology 60 years ago and has obtained approximately 120 high-voltage direct current transmission projects with a total installed capacity of over 130000 megawatts, accounting for about half of the global installation base.
