Power saving type active electric energy meter

Abstract

The present invention discloses an electricity-saving type active kilowatt-hour meter device. It can be directly mounted on the front end of user's incoming line, and includes power factor compensation unit, voltage regulation unit and main control unit containing regulation drive circuit. Said invention also provides the concrete function of every unit and its concrete structure, and provides their connection mode.

Description

technical field [0001] The invention relates to an electromechanical device for measuring the time integral of electric power or current, in particular to a power-saving active electric energy metering device. Background technique [0002] Most of the existing active energy meters only have a single measurement function, and do not have the functions of saving electricity and protecting electrical equipment. On the other hand, the more popular energy-saving motors, air conditioners, and refrigerators in the existing market are generally relatively expensive, the power-saving effect is greatly affected by the actual use environment, and users cannot obtain obvious power-saving benefits in a short period of time. In addition, the existing power supply voltage is generally high, and most of the time exceeds the design working voltage of electrical equipment. Long-term operation of electrical equipment at high voltage will easily lead to accelerated aging of electronic component...

[0002] Most of the existing active energy meters only have a single measurement function, and do not have the functions of saving electricity and protecting electrical equipment

On the other hand, the more popular energy-saving motors, air conditioners, and refrigerators in the existing market generally have the disadvantages that they are relatively expensive, the power-saving effect is greatly affected by the actual use environment, and users cannot obtain obvious power-saving benefits in a short period of time.

In addition, the existing power supply voltage is generally high, and most of the time exceeds the design working voltage of electrical equipment. Long-term operation of electrical equipment at high voltage will easily lead to accelerated aging of electronic components and insulation in the equipment, shortening the use of equipment life, and may cause safety accidents

In particular, some users have many types of electrical appliances with varying capacities. Each type of electrical appliance uses power-saving protection products, which is inconvenient to use and higher investment costs
