High-tension cable on high pressrue connection box and the high-tension cable volume car can adopt conventional fast-assembling safety electric wire connecting junction, to reduce the setting up time that wiring working strength and boats and ships reach port, increases work efficiency.
The removable use of high-tension cable volume car, safe and reliable, the folding and unfolding cable is quick and easy.Can be designed to electrical interlock between fast-assembling safety electric wire connecting junction and the boat-carrying transformer station, before wiring is accomplished and in the wiring process, the power supply of can not closing a floodgate of boat-carrying transformer station; If boat-carrying transformer station has been in power supply state, can not opens the junction box and carry out the wiring operation; All power supply outlet sides all adopt breaker protection, guarantee safety in utilization.
Consistent with the phase sequence of Ship Power Station to the power phase that boats and ships provide in order to guarantee boat-carrying transformer station, boat-carrying transformer station preferably is equipped with phase-sequence indicator, is used for detecting and the indication power phase, guarantees that marine electrical equipment normally moves.
Use shore electric power in order to satisfy large ship handling goods state, boat-carrying transformer station is designed to the use of can being incorporated into the power networks.The bank electricity access screen of Ship Power Station is connected with boat-carrying transformer station; Boat-carrying transformer station is to the sampling of Ship Power Station electrical network and compare calculating; The frequency of adjusting device power supply, voltage and phase angle are set up and spoke spare, realize boat-carrying transformer station and Ship Power Station parallel running, load transfer; Close marine generator then, realize supplying power to full ship free of discontinuities by boat-carrying transformer station.The change over switch that is incorporated into the power networks and is not incorporated into the power networks can also be set in the boat-carrying transformer station; When selecting not to be incorporated into the power networks; Realize and Ship Power Station electrical network interlocking; Guaranteeing could be by boat-carrying transformer station to ship power supply after the generation outage of Ship Power Station, and this working method is consistent with traditional shore connection box working method, and compatibility does not have bank electricity access screen or do not have the ship shore electric case of transformation to connect the use of bank electricity.
In order to overcome the utility grid supply variation; Overcome the electric power pressure drop that filter, transformer and supply line cause; Overcome the electric power pressure drop that the heavy load behaviour in service causes, guarantee the stable of supply power voltage, the utility model system can take multiple voltage stabilizing and indemnifying measure.Carry out voltage sampling from filter output, feed back to PLC and carry out the closed loop Voltage Stability Control; The PLC of high-pressure frequency-conversion supply unit sets up load through software setting---the voltage compensation curve model, guarantee the power supply compliant requirement of arrived ship electrical appliance.
Use the condition of the utility model system about boats and ships.Present most of boats and ships have possessed the condition that connects the bank electricity.General boats and ships; One or more boat-carrying transformer stations (shore connection box) have been installed; Can directly connect the bank electric system during boats and ships landing pier, electric power delivered to main distribution board carry out distribution, be provided with the attached cable of enough capacity between boat-carrying transformer station to the main distribution board.Have the stube cable of enough capacity and sufficient length between shore connection box to the shore electric power equipment; These cables generally are wound on the high-tension cable winch when ship's navigation; Can directly connect the bank electric system during boats and ships landing pier; Close marine generator, the power devices that replaces harbor generator to berth and use to boats and ships by the bank electric system through boat-carrying transformer station; Large ship has been installed boat-carrying transformer station (the bank electricity inserts screen); Perhaps increase boat-carrying transformer station through repacking; Can directly connect the bank electric system during boats and ships landing pier, realize and car, load transfer, close marine generator, supply power to full ship by the bank electric system through boat-carrying transformer station.
