Abstract

The invention relates to the technical field of deep sea mobile grab bucket high-voltage power supply, and discloses a high-voltage power supply system of a deep-sea movable grab bucket; the system comprises a deck high-voltage cabinet unit, an underwater transformer unit and a rectification bin unit. The transmitting end of the deck high-voltage cabinet unit is in signal connection with the receiving end of the underwater transformer unit; the transmitting end of the underwater transformer unit is in signal connection with the receiving end of the rectification bin unit; the transmitting end of the deck high-voltage cabinet unit is in signal connection with a deck control cabinet unit and the receiving end of a deck boosting transformer unit. The transmitting end of the deck boosting transformer unit is in signal connection with a pilot control unit and the receiving end of a digital display unit. When the high-voltage power supply system for the deep-sea mobile grab bucket is used, the deck high-voltage cabinet unit enables 380VAC three-phase alternating currents for ship power to be high voltage of four voltage grades of 1500V, 2000V, 2800V and 3300V through the deck boosting transformer unit, and transmits the high voltage to the underwater transformer unit of the mobile platform remotely, so that stable power supply operation can be ensured through the high voltage.

Description

technical field [0001] The invention relates to the technical field of high-voltage power supply for deep-sea mobile grabs, in particular to a high-voltage power supply system for deep-sea mobile grabs. Background technique [0002] According to the bulk density of the material to be grabbed, the grab is divided into three categories: light (such as grabbing grain), medium (such as grabbing gravel) and heavy (such as grabbing iron ore); according to the number of jaws, it is divided into double jaws Grab and multi-jaw grab, the most commonly used is the double-jaw grab. For large ore, iron filings and scrap steel, it is advisable to use a multi-jaw grab bucket, because it has the characteristics of multiple claws and sharp incisions, and is easy to insert into the stockpile, which can obtain better grabbing results. There is also a scissor grab that imitates the structure principle of scissors. Its grabbing force can gradually increase with the closing of the jaw plate, and...
