110V系统直流屏电池数量计算说明
因采用镉镍电池标称电压是1.2V,正常浮充电压为1.42~1.45V,合同要求92只，如果按1.42V计算正常浮充电压为92*1.42=130.V。
正常主充电压为1.55~1.65V, 合同要求92只，如果按1.55V计算正常主充电压为92*1.55=142.6V。
因正常使用母线电压130.＞110V*1.15=126.5。
建议采用85~87只使用，按87只计算，浮充电压为87*1.42=123.54，
主充电压为：87*1.55=134.85V.
正常使用母线电压为123.54＜110V*1.15=126.5
(注：主充尽可能不要高于母线正常运行电压太高)
Translation：
1. Nominal Voltage : Un=1.2V,
Floating Charge Voltage : Uf=1.42~1.45V.
Quick Charge Voltage : Uq=1.55~1.65V.
Quantity of Battery=92(nos)
According to above,
Floating Charge Voltage and Quick Charge Voltage For all the Battery should be as follow:Uf=(1.42~1.45)*92=130.~133.4(V)
Uq=(1.55~1.65)*92=142.6~151.8(V)
But the Voltage of Busbar which can be operated normally should be as follow:Um=110*1.15=126.5(V)﹤Ufmin=130.V﹤Uqmin=142.6V
So，it will affect the normal operation of all the DC equipment.
2. Nominal Voltage : Un=1.2V,
Floating Charge Voltage : Uf=1.42~1.45V.
Quick Charge Voltage : Uq=1.55~1.65V.
Quantity of Battery=85~87(nos), Calculated by 87 nos.
According to above,
Floating Charge Voltage and Quick Charge Voltage For all the Battery should be as follow:Uf=(1.42~1.45)*87=123.54~126.15(V)
Uq=(1.55~1.65)*87=134.85~143.55(V)
But the Voltage of Busbar which can be operated normally should be as follow:Um=110*1.15=126.5(V)﹥Ufmax=126.15V
So,it can be in normal operation.
