Advantages of working principle of power frequency Delta UPS power supply

Power frequency Delta UPS power supply uses digital signal processing technology to ensure fast and flexible measurement data, thereby generating fast control variables and ensuring real-time control of chargers and inverters.

Power frequency UPS power supplies have stronger short-circuit protection capabilities and stronger overload capabilities than high-frequency UPS power supplies.

Due to the extremely unstable urban electricity environment in China and its vulnerability to external conditions, the requirements for short circuit capacity and overload capacity are also higher. Using a power frequency UPS power supply will greatly improve the safety and stability of the load equipment.

??蓄电池的构造是什么?

1.极板
? ? ? ? ? 根据蓄电池容量选择适当规格极板及数量组合而成。于充放电时,两极活性物质随着体积的变化而反复膨胀与收缩。两极活性物质中，阴极板之海绵状铅的结合力较强，而阳极板之过氧化铅的结合力弱，因而在充放电之际，会徐徐脱落，此即为铅蓄电池寿命受到限制的原因。期使蓄电池使用期限延长，能耐震并耐冲击，则阳极板的改良即成当急要务。

玻璃纤维管式的阳极板: 此乃以玻璃纤维制的软管接在铅合金制的栉状格子(蕊金)上，在软管和蕊金间充填铅粉之后，将软管密封，使其发生变化，产生活性化物质，由于活性化物质不会脱落，与电解液接触亦良好,是一种非常好的极板材料。使用具有这种极板的蓄电池是电动车的选择。编织式软管乃以9microm(μ)的玻璃纤维编成管袋状，弹性好，可耐膨胀或收缩，而且对电解液的渗透度也非常良好，此软管乃是佳产品，以来，实用绩效良好。

糊状式极板: 就是将稀硫酸炼制之糊状铅粉涂覆在铅合金制的格子上，俟其 干燥后所形成之活性物质。这种方式一直被采用在铅蓄电池的阴极板上，同时亦使用在汽车，小货车的蓄电池阳极板上。

2.隔离板

能防止阴、阳极板间产生短路，但不会妨碍两极间离子的流通。而且经长时间使用，也不会劣化，或释放杂质。铅蓄电池一般都使用胶质隔离板。

3.电池外壳

耐酸性强，兼具机械性强度。电动车用的蓄电池外壳乃使用材质强韧之合成树脂经特殊处理制成，其机械性强度特别强，上盖亦使用相同材质，以热熔接着。

4.电解液

电解液比重以20℃的值为标准，电动车用的蓄电池完全充电时之电解液标准比重为1.280。

5.液口栓

液口栓的功能为排出充电时所产生的气体及补充纯水，测定比重。

What is the construction of the battery?

1. Plate

It is formed by selecting appropriate specifications and number of plates according to the battery capacity. During charging and discharging, the bipolar active material repeatedly expands and contracts with changes in volume. Among the bipolar active materials, the sponge like lead of the cathode plate has a strong binding force, while the lead peroxide of the anode plate has a weak binding force, which can slowly fall off during charging and discharging. This is the reason for the limited life of lead batteries. "In order to extend the battery life and to withstand shock and impact, the improvement of the anode plate becomes an urgent task.".

Glass fiber tubular anode plate: This is a flexible tube made of glass fiber connected to a conductive grid (core gold) made of lead alloy. After filling the hose and core gold with lead powder, the hose is sealed to make it change, producing an active substance. As the active substance does not fall off and has good contact with the electrolyte, it is a very good electrode plate material. Using batteries with such plates is the only option for electric vehicles. The braided hose is made of 9 microns（ μ) "Made of glass fiber woven into a tubular bag, it has good elasticity, is resistant to expansion or contraction, and has excellent permeability to electrolyte. This hose is the best product, with good practical performance f
