Abstract

本实用新型公开了一种电度表,是以传统的感应式电度表为基表增加磁电式脉冲发生器制造而成的电度表,为了克服因转动部件抖动而产生的伪脉冲,电度表中的霍尔传感器采用锁定型霍尔器件,这样基本上可以保证在一定范围(角度)内的抖动不会产生伪脉冲,从而保证电度表中用电量与输出脉冲之间的关系的准确。

Description

电度表
本实用新型涉及一种电度表，是以传统的感应式电度表为基表增加磁电式脉冲发生器制造而成的电度表。
将霍尔器件装在感应式电度表中，做成按圆盘的转动成比例的产生脉冲信号的电度表，如果采用单极型的霍尔器件作为脉冲发生器，则装在转动部件上的采样磁钢转到霍尔器件附近，并且产生一定的抖动(来回摆动)时，可能会在霍尔传感器上产生一系列不与用电量成比例的脉冲(称之为伪脉冲)，这是不希望的，也是不允许的。
本实用新型的目的是克服因转动部件抖动而产生的伪脉冲。
本实用新型的目的是这样实现的：一种电度表由传统的感应式电度表和脉冲发生器组成，所述的脉冲发生器由霍尔传感器和采样磁钢组成，霍尔传感器采用锁定型霍尔器件。
采用这样的技术方案基本上可以保证在一定范围(角度)内的抖动不会产生伪脉冲，从而保证电度表中用电量与输出脉冲之间的关系的准确。
下面结合附图对本实用新型的特点作进一步的描述。
图1是本实用新型的转动部件和霍尔器件的结构示意图。
图2是本实用新型的采样磁钢的安装图。
圆盘主轴(1)、圆盘(2)和采样磁钢(5)构成电度表的转动部件，采样磁钢(5)和霍尔器件(6)组成传感器(3)，(4)是定脉宽输出电路，采样磁钢(5)由两块以上的偶数块磁钢组成，图2列举了一种有两块磁钢的采样磁钢，这些磁钢均匀地安装在磁钢保持夹(9)上的磁钢槽(10)内，和霍尔传感器感应面相对的相邻两块磁钢的N极(7)和S极(8)相间。霍尔器件(6)采用锁定型的，它具有必须交替由N极和S极磁钢去感应，霍尔效应管才能每感应两次输出一个同极性的脉冲，不管用N或S极单一磁极的磁钢去连续感应，在第一次可能产生一个脉冲输出后，就不会产生第二个脉冲，因此，采用这种技术当电度表转动部件产生不大于(360度/2×磁钢对数)角度范围的抖动，就确保不会产生伪脉冲。
