阶梯值和阶梯区间阶梯电价方案的一种设置参数,阶梯值为D单位为kWh,阶梯区间是一个用电量的范围,单位为kWh。当阶梯值的数量为N时,可以将用电量范围划分为N+1个阶梯区间。2.阶梯电价管理方案阶梯电价管理方案包含确定阶梯值和对应的阶梯电价。例1:某阶梯电价方案确定3个阶梯值为D1、D2、和D3(单位为:kWh)。按照3个阶梯值划分的4个阶梯区间为W0、W1、W2、W3和确定对应的4个阶梯电价J0、J1、J2、J3,各阶梯区间的范围分别为:0≤W0≤D1、D1D3;阶梯电价单位为元,有两种表示方法:一种是直接的阶梯区间用电量的价格J0、J1、J2、J3,另一种是用阶梯电价与常规电价的差价表示方式:J'0、J'1、J'2和J'3,其中:J'0=0、J'1=J0-J1、J'2=J1-J2、J'3=J2-J3。阶梯电价与常规电价的差价表示方式用于阶梯费率电价管理比较方便。阶梯电价与常规电价的差价可以是正数、0或负数。1.功能用户持IC卡到供电部门交款购电,供电部门用售电管理机将购电量写入IC卡中,用户持IC卡在感应区刷非接触式IC卡(简称刷卡,下同),即可合闸供电,供电后将卡拿走。当表内剩余电量等于报警电量时,拉闸断电报警(或蜂鸣器报警),此时用户在感应区刷卡即可恢复正常,此时用户在感应区刷卡即可恢复供电。崇明区制造AD16系列蜂鸣器型号在陶瓷片的两面镀上银电极,经极化和老化处理后,再与黄铜片或不锈钢片粘在一起。
蜂鸣器 拔下电源线,用镊子短路三脚插头的两个供电插脚,测另一头三芯插孔的两个供电插孔间的电阻为零,拿开镊子时电阻变为无穷大,说明电源供电线完好,不存在开路和短路故障。测电脑电源各输出脚对地间的电压全部为0V,在紫线与黑线间测不到5V待机电压,绿线与黑线间电压也为0V。拆开电脑电源盒,测电源输入端正反向电阻均为无穷大,测TUBE6A保险丝烧断。测C121两端正向电阻为无穷大,反向电阻为487Ω。C122两端正反向电阻都为13Ω。沿电路找到并联在C121两端的压敏保护电阻RV121(TVR10241X)由黄色变为红色,并被烧缺一块。RV122(TVR10241X)直接被击穿为13Ω,但仍为黄色。测查所有晶体管和大功率管及输出电路的所有整流二极管和滤波电容,对可疑元件逐一拆下检测,未找到击穿、漏电或开路元件。由电路的连接方式可以推断出,TVR10241X的保护电压应该是MYC10K471保护电压的一半。用一个MYG10K471彩电整流滤波输出端的保护压敏电阻,一脚焊接到C121的正极,一脚焊接到C122的负极,将两个串联保护的压敏电阻改为一个,以提高保护的灵敏度和可靠性,更换保险。通电测C121和C122两端的电压分别依次为156V,MYG10K471两端的电压为313V,比彩电中该电阻两端电压298V高5V。
