Marine batteries include generator sets on board, signal light, emergency lighting, instrumentation, photovoltaic power reserves, no type of application range, different types of battery requirements, Belons has more than fifteen years, understand the daily life of the ship The battery power supply is required, and the price, installation, model, performance, technical agreement, etc. of the marine battery can be quickly available for different grades of applications.1. Type: The battery is also known as the secondary battery, and is an electrical device that stores the obtained electrical energy in the form of chemical energy and can convert chemical energy into electrical energy. The battery is different from the electrolyte, usually divided into an alkaline battery and an acid battery. In recent years, due to the high-speed development of transportation, communication, computer industry, its product range, product type, product performance have changed to meet the needs of different purposes.
The battery is mainly used in various vehicles, ships, airlines, other internal combustion engines, and lighting, ignition, energy storage, emergency power, telephone switches, uninterruptible power, mobile communication, computer, electronic, instrument, portable electric tool, electric toys, etc. In short, in national defense, industrial and agricultural production, transportation, electricity, electronics, communications, teaching, scientific research, medical and health, and people's daily life. With the rapid development of transportation, energy, communications, electronics and computer industries, China has developed rapidly, until the beginning of the 1990s, there are many companies engaged in battery production, including maintenance, valve-controlled lead-acid battery, metal The outlet of new storage batteries such as oxide nickel battery, lithium-ion battery has an upward trend.
Common vessel storage battery, cadmium-nickel battery, iron nickel battery, metal oxide storage battery, zinc silver battery, zinc nickel battery, hydrogen-nickel battery, lithium ion battery, etc.
1 lead-acid battery negative is lead, the positive electrode is a lead, the electrolyte is sulfuric acid, mainly a start type, fixed type, traction type, power type, and portable, most of which are open or anti-acid, small amounts of colloidal electrolyte batteries. In recent years, sealing lead acid and other types of battery products have replaced the original lead-acid batteries in many fields. The lead-acid battery has a low price, suitable for low temperature high magnification discharge, widely used. However, since the lead-acid battery is low, the production process is toxic, polluted environment, affects the scope of use.
2 Cadmadi-nickel battery negative is cadmium, positive extremely nickel oxide, and electrolyte is aqueous potassium hydroxide aqueous solution. Frequently in shape is square, fastening and cylindrical, three structures that are open, sealed and full sealing. The polar plate is also divided into a plate, sintered, compressed and pulp. The cadmium-nickel battery has the characteristics of high discharge magnification, good low temperature performance, long cycle life.
3 Metal hydride nickel battery is a new product developed in the 1980s. The negative is an absorbent hydrogen-hydrogen-free earth alloy. It is extremely nickel oxide. The electrolyte is potassium hydroxide, a lithium hydroxide solution, which is 1.5-2 times larger than cadmium nickel battery. Capacity, fast charge, excellent high-magnification discharge performance and low temperature discharge performance, cheap, non-polluting, called green environmentally friendly batteries.
4 iron nickel battery negative is iron powder, the positive electrodes are nickel oxide, and the electrolyte is a solution of potassium hydroxide or aqueous sodium hydroxide. It has the characteristics of strong structural strength, durability, long life, low specific energy, mostly used in the power supply of mine transport vehicles.
5 zinc silver battery negative is zinc, positive for silver oxide, electrolyte is aqueous potassium hydroxide aqueous solution, with high ratio energy, excellent high-magnification discharge performance, but high, mostly used for military industrial and weapon systems.
6 Zinc nickel battery negative is zinc, positive extremely nickel oxide, electrolyte is aqueous potassium hydroxide aqueous solution, with high ratio energy, low price, short life, has a relatively improvement of circulating life of zinc nickel battery in recent years, The increase in cycle life will be wider.
7 Lithium ion battery negatives are carbon (graphite), and the positive electrode is lithium oxide, and the organic electrolyte has a high voltage, high than energy, excellent circulating life, and has no pollution, referred to as a green power supply.
Marine batteries must meet the following points:
(1) Adapt to vibration and impact. Vibration can make the fixation or connecting components of the electrical equipment to make the component structure damage or fail. Therefore, there must be anti-loose measures, damping or vibration-enrichment measures, with rugged vibration and impact mechanical structures.
(2) Adapt to tilt and swing. Sustained tilt and swaying disrupt the balance of the normal stationary position, which generates an additional force to the moving parts, causing equipment failure or damage.
(3) Adapt to the ambient temperature. Ambient temperature has an important impact on the performance and service life of electrical equipment. The ambient temperature includes air temperature and seawater temperature.
(4) Adapt to the environment of moisture, salt fog, oil mist and mold. The humidity of the ambient air, the salt fog, oil mist and molds cause the electrical equipment insulation to reduce the insulation properties of the electrical equipment, so that the metal parts produce rust and corrosion. Wet salt fog forms a humid leakage film on the surface of the insulating material, secreting organic acids under wet heat conditions, exacerbated the humidity of the surface. Oil mist and dust are adhered to the surface of the surface to increase the leakage of the surface, and hinder heat dissipation makes the temperature rise. Wet water molecules are infiltrated into the cracks and capillary holes of the insulating material, resulting in increased leakage current, resulting in lower insulation resistance. Many electrical equipment damage is often caused by the thermal shot of the insulating material. Since the temperature exceeds a certain limit, the aging of the insulating material will be accelerated, and the insulation performance is lost. Therefore, the ship cable, wire, winding, etc. need to be highly heat-resistant, resistant to moisture resistance, anti-salt fog, anti-bacteria insulation, good flame retardancy, good mechanical strength and corrosion resistance.
(5) Adapt to changes in the voltage and frequency of the ship. Ship power systems are one independent limited grid. The voltage and frequency are affected by the load change, so the range of changes in voltage and frequency is specified, and it is possible to work within this range.
(6) Protection requirements. In order to avoid malfunction or damage to an electrical equipment from an external solid and liquid foreign matter, thereby causing fire hazards, and general electrical equipment should have a shell cover.
