SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a safe and reliable and simple structure's direct current network deployment system based on lithium cell.
The utility model adopts the technical proposal that: the utility model discloses a plurality of lithium cell groups, direct current distribution board, propulsion motor and output transformer, be provided with the direct current on the direct current distribution board and arrange female, a plurality of the lithium cell group all through the direct current converter and the first direct current circuit breaker that connect gradually with the female electricity of arranging of direct current is connected, propulsion motor through the first dc-to-ac converter and the second direct current circuit breaker that connect gradually with the female electricity of arranging of direct current is connected, output transformer pass through second dc-to-ac converter and third direct current circuit breaker with the female electricity of arranging of direct current is connected.
According to the scheme, a plurality of lithium battery packs are used for providing electric energy for a power grid. The direct current distribution board is arranged to provide integration of conversion elements, so that the elements are centralized and convenient to produce and assemble. The direct-current busbar is used for conducting the lithium battery packs and loads. The voltage output by the lithium battery pack is converted by the direct current converter, and the first direct current circuit breaker, the second direct current circuit breaker and the third direct current circuit breaker are used for controlling the on-off of the circuit and protecting the circuit. The first inverter and the second inverter are used for converting direct current output by the lithium battery pack into alternating current and supplying the alternating current to the propulsion motor and the output transformer. The output transformer is used for outputting electric energy to a load on the ship.
According to a preferred scheme, a fourth direct-current breaker and a third inverter which are connected in sequence are arranged on the direct-current busbar, and the third inverter is connected with an external charging head in a matched mode.
According to the scheme, the third inverter is matched with an external charging head to charge the lithium battery packs, and alternating current is converted into direct current through the third inverter and is transmitted to the lithium battery packs. And the fourth direct current breaker is used for controlling the on-off of the charging circuit and the protection of the circuit.
The number of the propulsion motors and the number of the output transformers are two groups, an isolation circuit breaker is arranged on the direct current busbar, the propulsion motors are arranged on two sides of the isolation circuit breaker respectively, and the output transformers are arranged on two sides of the isolation circuit breaker respectively.
According to the scheme, the isolation circuit breaker is arranged to divide the direct-current busbar into two independent sections, so that two groups of electric loads can operate independently.
