Abstract
The utility model provides an energy-saving electric meter which comprises a voltage coil, an iron core, a current coil, an iron core, a braking permanent magnet and an aluminium disk, wherein, a bidirectional thyristor is connected with the voltage coil in series, and the current coil is connected with a current mutual inductor which can trigger the bidirectional thyristor in series. The utility model has the advantages of novel structure and energy saving, and besides, the voltage coil does consume electricity at the time of no load.
Description
The utility model relates to a kind of watt-hour meter, particularly be a kind of energy-saving kilowatt-hour meter.
The watt-hour meter of China's use at present mainly comprises potential winding and iron core, current coil and iron core, braking permanent magnet, counter, aluminium disk.No matter whether this watt-hour meter user power utilization, potential winding is connected in the power circuit all the time.If user's electricity consumption every day 8 hours just has unloaded power consumption in 16 hours, waste is big.
The purpose of this utility model is for a kind of energy-saving kilowatt-hour meter of not power consumption of potential winding when non-loaded is provided.
The utility model is to be in series with bidirectional triode thyristor on the basis of former watt-hour meter on potential winding, and series connection can trigger the current transformer (referring to Fig. 1, Fig. 2) of bidirectional triode thyristor in current coil.
The utility model novel structure, not power consumption of potential winding, energy-conservation when non-loaded, long service life.
Below in conjunction with description of drawings embodiment of the present utility model:
Fig. 1: the utility model structural representation
Fig. 2: the utility model circuit diagram
The utility model is made up of potential winding and iron core 1, current coil and iron core 2, braking permanent magnet 3, counter 4, aluminium disk 5, the bidirectional triode thyristor 6 of connecting with potential winding and iron core 1, the current transformer 7 of connecting with current coil and iron core 2, the resistance 8 that is connected on 7 of bidirectional triode thyristor 6 and current transformers.Bidirectional triode thyristor 6 is optional to be that 1 peace, voltage be 400 volts, trigger current less than 3 milliamperes, trigger voltage are 330 ohm high sensitivity bidirectional triode thyristor less than 2 volts of resistance with electric current.Primary winding in the current transformer 7 forms around 100 circles with 1 millimeter enameled wire of Φ, and secondary coil adopts Φ 0.08-0.1 millimeter enameled wire to form around the coiling of 100-150 circle, and iron core is selected the iron core of the transformer shape of the mouth as one speaks below 1 watt for use.
When load is opened, exchange current arrives load 9 through current coil 2 to current transformer 7 primary winding, in current transformer 7 secondary coils, produce the interchange trigger pip identical with supply frequency, add to bidirectional triode thyristor 6 controls through current-limiting resistance and trigger bidirectional triode thyristor 6 conductings, potential winding 1 is charged, the utility model work, this moment, duty and common electrical kilsyth basalt were identical, and household electrical appliance are had no effect.
When load 9 was closed, no current passed through on load 9 and the current transformer 7, and current transformer 7 Triggerless produce, bidirectional triode thyristor 7 Triggerless and turn-offing, and potential winding breaks away from power supply, has eliminated the unloaded power consumption of potential winding.
