Description

Technical Field

[0001] This invention relates to a bottom cable extension box for an E-House high-voltage switchboard. Background Technology

[0002] FPSO is a key piece of equipment in the offshore oil and gas industry. The stability of its power system directly affects operational safety and efficiency. As the core of FPSO power control, the reliability of the high-voltage switchboard cable entry in the E-House is crucial. Traditional bottom-entry cable entry methods for high-voltage switchboards suffer from limited wiring space, messy cable layout, and insufficient sealing performance. Therefore, researching a better E-House high-voltage switchboard cable entry extension box is of great significance. Summary of the Invention

[0003] The purpose of this invention is to provide a bottom cable extension box for E-House high-voltage electrical panel that allows for the orderly laying and layout of multiple cables.

[0004] The technical solution adopted by the present invention to achieve the above objectives is: an E-House high voltage power panel bottom cable extension box, including a box body (1), a steel sleeve (2), a circular MCT sleeve (3) and rubber insulation (4). The box body (1) is installed below the deck (5), the steel sleeve (2) is installed at the bottom of the box body (1), the circular MCT sleeve (3) is installed at the top of the steel sleeve (2), and the rubber insulation (4) is filled in the lower part of the steel sleeve (2).

[0005] The box (1) is made of steel plate.

[0006] The steel sleeve (2) is a galvanized steel sleeve.

[0007] The circular MCT sleeve (3) is provided with a circular hole for threading the cable (6).

[0008] This invention relates to a bottom-entry cable extension box for E-House high-voltage electrical panels. It features a simple structure and can be designed and constructed simultaneously during the ship's design phase. This effectively increases the wiring space at the bottom of the high-voltage electrical panel, solving the problem of insufficient space and facilitating on-site construction. The use of a circular MCT (Mechanical Control Unit) and galvanized steel conduit allows for the orderly installation and layout of multiple cables, simplifying future maintenance and repair, reducing electromagnetic interference, reliably improving sealing and insulation performance, and enhancing equipment lifespan and electrical safety.

[0015] like Figures 1 to 6 As shown, the E-House high-voltage switchboard bottom cable extension box includes a box body 1, a steel sleeve 2, a circular MCT sleeve 3, and rubber insulation 4. The box body 1 is installed below the deck 5, the steel sleeve 2 is installed at the bottom of the box body 1, the circular MCT sleeve 3 is installed at the top of the steel sleeve 2, and the rubber insulation 4 fills the lower part of the steel sleeve 2. The box body 1 is made of steel plate, the steel sleeve 2 is made of galvanized steel, and the circular MCT sleeve 3 has a circular hole for passing through the cable 6. The box body 1 is set under the deck 5 at the bottom of the high-voltage switchboard. The height of the box body is 450mm, and the width is the same as the width of the high-voltage switchboard to meet the requirements of the high-voltage switchboard cable inlet hole. It uses steel plate of the same material as the hull structure and is designed as an integral part of the hull structure. The hull deck is hollowed out between the bottom of the high-voltage switchboard and the extension box, so that the inside of the equipment and the extension box form an integral whole, effectively increasing the wiring space at the bottom of the high-voltage switchboard. The galvanized carbon steel sleeve 2 is compatible with the circular MCT sleeve 3 and is installed at the bottom of the extension box box body 1. The length of the steel sleeve 2 is... The 150mm diameter ensures that the cable enters the enclosure vertically. A circular MCT sleeve 3 is installed on top of the galvanized carbon steel sleeve. Several circular MCT sleeves 3 are used to thread cables 6, achieving an orderly layout of multiple cables and avoiding cable clutter and interference. Multiple cables can be neatly arranged inside the circular MCT sleeve 3, facilitating quick identification and operation during later maintenance and repair. The lower part of the galvanized carbon steel sleeve 2 is filled with rubber insulation 4, which not only provides insulation but also buffers the friction between the cable and the steel sleeve, further improving sealing performance and preventing moisture from entering the enclosure. The circular MCT sleeve can be selected for single or multiple cables as needed, making cable arrangement more convenient. This invention, the bottom-entry cable extension box of the E-House high-voltage electrical panel, has a simple design and structure, effectively solving the problems of limited wiring space and cluttered cable layout at the bottom of the E-House high-voltage electrical panel. It also further improves sealing performance, facilitating both on-site construction and later maintenance and repair, thus improving work efficiency.
