Electrical equipment.
On boats with outboard motors that have no electric start, often the only source of electricity is magdino, which produces alternating current, 12 V power from 30. It allows you to feed the signal lights and headlight motor boats, and includes all current users at the same time, or turns one, but absorbs at least 2 / 3 power coming from the generator coils magdino. Otherwise, due to overexertion thin bulb lights, lights, and so n can be damaged. Meals onboard network via a simple rectifier. By this rectifier can be connected for charging on the go boat battery, which provides electricity to customers in the parking lot. Bridge rectifier provides a charging current to 4 A simple diode - to 1.5 A.
When installing batteries on boats and yachts often prefer to use 12 V, which makes it possible to use standard lighting equipment and appliances, manufactured for automobiles. At this voltage is calculated as many portable radios, instruments, and so n. On small vessels without engine with electric start, prefer to maintain alkaline batteries, including a pair of identical sequence 6voltovyh batteries. Note that the operating conditions the battery on the boat is quite different from conditions in the car. The boat used in the battery discharge regime for quite some time, battery chargers when not working. By car battery as the main purpose - to provide short-term, but a strong current to the starter and the rest of the battery is not used or operates in charge.
For vessels without a stationary engines, such as sailing boats, where there is no possibility of an autonomous periodic recharging, battery capacity is chosen from the condition of maintenance of navigation lights and lighting at the minimum period between calls at the ports, which can be recharged from a coastal network. For this table is made of energy, which account for power users and the duration of their use during the day.
To make better use of starter battery acid batteries, which provide large inrush currents. For boats with engines converted from passenger cars use batteries with a capacity of 45-60 A. h. This is enough to scroll through the starter motor for up to 10 minutes. And when you consider that in the summer time the engine is started in seconds, for purposes of illumination can be used up to 50% capacity batteries. |
