摘要： A feed line switching circuit includes a relay connected between feed lines, a normally close contact of the relay, and a resistor that constitutes a series circuit with the normally close contact, which series circuit is connected in parallel with the relay. The resistance of the coil of the relay and the resistance of the resistor are determined to satisfy the condition that the current flowing through the relay after energizing the relay can prevent the chattering of the relay. Thus, the feed line switching circuit can positively carry out the feed line switching.

摘要： The present invention discloses a submarine observation system in which a plurality of carrier lights assigned to each submarine observation equipment is transmitted from a land terminal apparatus to an optical submarine cable (down-going) by using a WDM transmission. In the submarine observation equipment, only a prescribed carrier light is demultiplexed by an optical demultiplexer, an observation signal indicating an observation result is generated by an observation device, intensity of the carrier light demultiplexed by the optical demultiplexer is modulated by an optical amplifier based on an observation signal, and the modulated carrier light is multiplexed by an optical multiplexer. The multiplexed carrier light is output to the optical submarine cable (up-going) to be returned to the land terminal apparatus being the transmission station. The land terminal apparatus is able to obtain an observation signal of each observation point by separating carrier lights based on each wavelength and receiving a separated carrier light of each wavelength. Accordingly, the system can be structured with one optical fiber and can be extendable by increasing or decreasing carrier lights, and either one of the land terminal apparatuses can receive an observation signal even when the optical submarine cable is cut off.

摘要： A submarine power feeding branching device comprises a constant current-constant current converter which isolates an input side for a trunk submarine cable from an output side for a branch submarine cable. The converter receives a first constant current and produces a second constant current by using the first constant current. The second constant current is supplied to the output side while the first constant current is returned to the input side. Because the input side and the output side are isolated, it is easy to add/remove the device to/from a submarine power feeding system. Intensity of the second constant current can be controlled by controlling duty ratios of switches included in the converter. Thus, it is possible that the intensity of the second constant current is equal to that of the first constant current. Therefore, a submarine repeater can be provided along either the trunk cable or the branch cable.
摘要翻译：潜艇供电分支装置包括恒流恒流转换器，其将用于干线海底电缆的输入侧与分支海底电缆的输出侧隔离。转换器接收第一恒定电流并通过使用第一恒定电流产生第二恒定电流。第二恒定电流被提供给输出侧，而第一恒定电流返回到输入侧。因为输入侧和输出端是隔离的，所以很容易将设备添加到/从海底供电系统中去除。可以通过控制转换器中包括的开关的占空比来控制第二恒定电流的强度。因此，可以使第二恒定电流的强度等于第一恒定电流的强度。因此，可以沿着中继电缆或分支电缆提供潜艇中继器。
