Counter of multifunctional electric energy meter

Abstract

The invention discloses a counter of a multifunctional electric energy meter. The counter comprises three-phase six-wire wheels, a three-phase six-wire toothed shaft, number wheels, a number wheel shaft, a support, a motor and a gear groove. A bracket for supporting the three-phase six-wire toothed shaft is arranged at the bottom of the support. A sliding gear is arranged in the gear groove. A stop gear is arranged on a dust cover. A fixing lug is arranged on the support. By arranging the bracket for supporting the three-phase six-wire toothed shaft at the bottom of the support, no matter how great the impact or shock is, the situation that the number wheels are dislocated is avoided; and by arranging the sliding gear in the gear groove and arranging the stop gear on the dust cover, the goal of preventing the counter from rotating reversely can be achieved, the behaviors of stealing electricity are effectively prevented, the structure is simple, the cost is low and the counter can be widely used by power supply departments and is worthy of being popularized.

Description

1. Technical field: [0001] The invention relates to a counter, in particular to a counter for a multi-functional electric energy meter which can prevent the counter from being reversed and the character wheel from being dislocated. 2. Background technology: [0002] With the development of the national economy, the field of residential electricity consumption continues to expand. Various electronic energy meters operating in the current grid have gradually eliminated mechanical energy meters due to their advantages such as large capacity and high sensitivity. However, during operation, a large number of Electricity theft cases, that is, using the magnetic force generated by the external strong magnetic coil, the electric energy meter can be stopped or even reversed without turning on the electric energy meter. With the continuous development of science and technology, the means are becoming more sophisticated and Concealment has caused certain losses to the country and t...

[0002] With the development of the national economy, the field of residential electricity consumption continues to expand. Various electronic energy meters operating in the current grid have gradually eliminated mechanical energy meters due to their advantages such as large capacity and high sensitivity. However, during operation, a large number of Electricity theft cases, that is, using the magnetic force generated by the external strong magnetic coil, the electric energy meter can be stopped or even reversed without opening the electric energy meter. With the continuous development of science and technology, the means are becoming more sophisticated and more Concealment, causing the country and the collective to suffer certain losses

At present, there are various types of anti-stealing watt-hour meters at home and abroad, because of their poor anti-stealing effect, inconvenient operation, inaccurate judgment, inability to automatically reset, and large spans of three and six tooth shafts can easily lead to word wheel misalignment. and other reasons, so it has not been widely adopted by the power supply department
