[0003] In the prior art, the power supply of the ship's emergency escape guide light belt is obtained by transforming the 220V voltage of the ship's power system to 36V through the isolation transformer in the collector box, but in case of emergency or due to work needs, disconnect the collector box When the power is turned on, the emergency escape guide light strips will all lose power, unable to illuminate and guide the escape passage, which seriously affects the emergency escape of the ship
[0004] Because there is no such 36V low-voltage emergency power supply equipment on the market, it is urgent to develop a low-voltage emergency power supply that can still normally supply power to the escape guide light belt when the ship is powered off, so as to ensure the normal operation of the ship's emergency escape guide light belt. run

The invention relates to the technical field of ships, and specifically relates to a marine emergency escape guide lamp strip power supply system including a low-voltage alternating-current power supply provided by the ship electrical system, the voltage output terminal of the low-voltage alternating current power supply is connected with a first power supply loop which directly supplies power tothe emergency escape guiding lamp of the ship, the voltage output terminal of the low-voltage alternating current power supply is respectively connected with a second power supply circuit and an alternating current contactor KM, the second power supply circuit comprises a T1 transformer connected in sequence from a voltage output terminal of the low-voltage AC power supply to a load terminal, a charger, a battery pack, an air switch, an emergency escape guiding lamp band, and the AC contactor KM is provided with a normally-open contact and a normally-closed contact, wherein the normally-open contact is connected in a first power supply circuit, and the normally-closed contact is connected in a second power supply circuit. The invention can ensure that the ship normally supplies power to the escape guiding lamp belt under the power-off condition, thereby improving the emergency treatment level of the ship.
Description
Technical field [0001] The invention relates to the technical field of ships, in particular to a power supply system for a ship's emergency escape guide light. Background technique [0002] Ship emergency escape guide light strips are used to illuminate the escape route of ships in emergency situations. [0003] In the prior art, the power supply of the ship’s emergency escape guide light belt is obtained by transforming the 220V voltage of the ship’s power system into 36V through an isolation transformer in the collection box, but the collection box is disconnected in an emergency or due to work. When the power is supplied, the emergency escape guidance light strip will all lose power, and it will not be possible to illuminate and guide the escape passage, which seriously affects the emergency escape of the ship. [0004] Since there is no such 36V low-voltage emergency power supply equipment in the market, there is an urgent need to develop a low-voltage emergency power supply tha...
