三、表损电能表也是一个用电器,只要接入电路就要消耗电量.电能表本身消耗的电量我们叫表损.当一个总表后面有许多分表时,总表的读数总是比所有分表读数的和还要大.根据电能表标准规定,我们日常使用的单相电能表每月平均消耗电量为0.74kw·h左右.所以,有的地方规定,一只单相电能表每个月可加表损比1kW·h(加线损的,不得同时再加表损).线损、变损、表损是客观存在的,它们的存在提高了电的价格.但是,我们可以采取各种措施来减少这些损耗,节约能源,降低电价.第二章 电能计量第一节 电能计量几种形式电能表是电力部门的“称杆子”,也是用户用电计
Third, the loss meter is also a use of electrical appliances, as long as the access circuit will consume electricity. Electricity meter itself consumes electricity, we call the table loss. When a total table behind many sub-tables, the total table reading is always better than all The reading of the submeters is even larger. According to the standard of the electric energy meter, the average monthly electricity consumption of the single-phase electricity meters we use every day is about 0.74kw·h. Therefore, in some places, a single-phase energy meter is required. Month can be added to the surface damage ratio of 1kW · h (plus line damage, not at the same time plus surface damage). Line loss, damage, surface damage is an objective reality, their presence increases the price of electricity. However, we can take Various measures to reduce these losses, save energy, and reduce the price of electricity. Chapter II Energy Metering Section 1 Energy Metering Several forms of energy meters are the “power levers” of the power sector, and are also power meters for users.
