Electrical wiring system for tidal current energy unit

Abstract

The invention discloses an electrical wiring system for a tidal current energy unit. The system comprises an electrical sealed cabin which is disposed on a floating type overwater platform and comprises a converter cabinet, a transformer cabinet, and a main control cabinet; the underwater tidal current energy generator set comprises a wiring terminal box, a generator, a gear box and a hub, and a main control cabinet is connected with the generator, the gear box and the hub through the wiring terminal box and is electrically controlled; the submarine cable protection pipe is arranged between the electrical sealed cabin and the tidal current energy generator set and comprises a first cable wiring bridge frame and a second cable wiring bridge frame, and power cables of the converter cabinet,the transformer cabinet and the main control cabinet are connected with a wiring terminal box in the tidal current energy generator set through the first cable wiring bridge frame; signal cables of the converter cabinet, the transformer cabinet and the main control cabinet are connected with the wiring terminal box through a second cable wiring bridge. The sealing performance of the tidal currentenergy generator set is ensured; the cable is prevented from being eroded by seawater; and the functions of power supply and communication with the underwater tidal current energy generator set are realized.

Description

technical field [0001] The invention relates to the field of tidal current energy generation, in particular to an electrical wiring system of a tidal current energy unit. Background technique [0002] At present, my country has been developing tidal current power generation devices for many years. Tidal current power generation units are generally composed of impeller systems, mechanical transmission systems, electrical systems, control systems, sealing systems, corrosion protection systems, and monitoring systems. Among them, the impeller system is composed of blades and hubs, which captures the kinetic energy of the ocean tide and converts it into mechanical energy; transmits energy through the transmission system composed of the main shaft, gearbox and coupling cabin; The connection of converters, transformers and control cabinets above the plane; the control system realizes the safe operation of the unit during start-up, power generation and shutdown; the sealing system ...

AI Technical Summary

Problems solved by technology

[0003] The tidal current energy generating set is located underwater. If the converter cabinet and the main control cabinet are placed inside the tidal current energy generating set and placed underwater together with the common wind power generating set, on the one hand, the electrical components in the cabinet are in a humid environment. It is easy to break down, and the tidal current energy generating set needs to be lifted above the sea surface for maintenance during maintenance and repair. The maintenance cost is high, and on the other hand, it is not conducive to the operation of the tidal energy generating set by human operation
