Underwater non-contact type separable transformer for electric energy transmission based on butterfly magnetic core

Abstract

The invention relates to an underwater non-contact type separable transformer for electric energy transmission based on a butterfly magnetic core, which comprises an upper moving magnetic core mechanism and a lower fixed magnetic core mechanism, wherein the upper moving magnetic core mechanism comprises an upper tray which is fixed into a whole with the upper moving magnetic core mechanism, a first ferrite magnetic core, a striker and a secondary winding; the lower fixed magnetic core mechanism comprises a lower tray which is fixed into a whole with the lower fixed magnetic core mechanism, a second ferrite magnetic core, a cylinder and a primary winding, and the inner bottom surface of the cylinder is provided with a cushion pad. The invention adopts an electromagnetic coupling structure to realize the non-contact transmission of underwater electric energy so as to avoid the physical contact and the electrical connection of an electricity transmission interface and guarantees that theprimary winding and the secondary winding of the separable transformer can also maintain better electromagnetic coupling under the condition of a larger gap through the butterfly magnetic core with acentral post. The invention has simple structure, pressure resistance, good air tightness, high reliability and convenient maintenance and effectively overcomes the defects of low safety and high manufacturing cost of the underwater electricity transmission interface.

Description

technical field [0001] The invention relates to a separable transformer used in an underwater environment and capable of transmitting electric energy in a wide working gap. Background technique [0002] Underwater mobile devices are usually powered by electricity, but water is usually a good conductor of electricity in the environment. If the underwater power transmission adopts the exposed conductor contact method like the land power transmission, it will be difficult to seal and easy to leak. In order to enable underwater mobile equipment to move freely without the power transmission device after being charged, the current method that is widely used is to provide power to mobile equipment underwater through wet plug connectors, but the price of such connectors is as high as more than 100,000 yuan. Promotional applications are very limited. The non-contact power transmission method transmits power through the separable transformer with the primary side and the secondary s...

Problems solved by technology

However, the underwater environment is complex and changeable, and debris, underwater organisms, etc. often fall and adhere to the surface of the equipment, which limits the application of separable transformers with small working gaps. Therefore, a transformer that can transmit electric energy in a wide working gap is needed. separable transformer
