The utility model is provided with a bidirectional thyristor BCR and one electrode of the thyristor connects with a voltage coil L2. The utility model is provided with two diodes D1 and D2 connected end to end, one end of the diode D1 is a zero line output end (5), the output end (5) connects with a control pole of the thyristor, the other end of the diode D1 is a zero line input end (4) and the input end (4) connects with a capacitor (4) in series and then connects with the other electrode of the thyristor. The energy-saving device makes use of the forward voltage drop of the diodes to control the bidirectional thristor's conduction and cutoff.
Description
The utility model relates to a kind of energy-saving control device of family expenses watt-hour meter.
In the prior art, application number is that 922294917 utility model patent discloses a kind of " family expenses watt-hour meter energy-saving appliance ".This energy-saving appliance is made of a current sensor, two diodes, two stabilivolts, a controllable silicon and a resistance.When current sensor elementary had electric current to flow through, the voltage triggered controllable silicon conducting that its secondary generation is certain made the meter voltage coil operate as normal; If the current sensor no current passes through, its secondary no-voltage, controllable silicon ends, and so promptly reaches when watt-hour meter is empty to be cut the not energy-conservation purpose of consumed power.This energy-saving control device has following shortcoming: 1, used no part is more, and cost is higher; 2, the secondary coiling number of current sensor is more, and speed of production is too slow; 3, be difficult for reaching the measurement standard of watt-hour meter, when load hour, promptly the electric current by watt-hour meter hour because the shunting and the metering function of four diodes and a resistance, make the controllable silicon can not conducting or conducting fully, can shadow noon the measuring accuracy of watt-hour meter.
The purpose of this utility model is to provide a kind of lower-cost family expenses watt-hour meter energy-saving control device, and this device has tangible power savings, does not influence the measuring accuracy of watt-hour meter.
The purpose of utility model realizes by following mode.
The energy-conservation system device of family expenses watt-hour meter, a bidirectional triode thyristor BCR is arranged, electrode of this silicon controlled is connected with the potential winding of watt-hour meter, also have two end to end diode D1 and D2, the end of diode and D1 is the zero line output terminal, and this output terminal is connected with the control utmost point of controllable silicon BCR, and the other end of diode D1 is the zero line input end, this input end serial connection capacitor C 2 links to each other with another electrode of silicon controlled again.
When the current coil of load electricity consumption, watt-hour meter has electric current to flow through, the two ends of diode D1 and D2 just produce a pressure drop, this pressure drop can trigger the controllable silicon conducting, after the controllable silicon conducting, the two ends of meter voltage coil promptly produce normal voltage, watt-hour meter promptly begins to run well, when not electricity consumption of load, no current flows through in the meter current coil, diode D1 and D2 two ends do not have pressure drop, bidirectional triode thyristor ends because of triggerless voltage, and no current flows through in the potential winding, thereby has played watt-hour meter energy-conserving action of consumed power not when unloaded.
The family expenses watt-hour meter energy-saving control device that the utility model provides, be utilize diode forward voltage drop control bidirectional triode thyristor conducting with end, reach energy-conservation purpose.The forward voltage drop of two big electric current diodes is subjected to the influence of load current size hardly, and its trigger voltage is stable, and is highly sensitive, so this device does not influence the measuring accuracy of watt-hour meter.This device can bear bigger rush of current, even load short circuits, big electric current diode also can be to be burnt out.Because diode is reverse withstand voltage lower, in case one of them diode damages, another diode will be breakdown thereupon, thus can not damage because of one of them diode, and obtain dc pulse moving voltage at the load two ends.The power consumption of this device own is minimum, and its structure is very simple, and used element is seldom manufactured easily, and cost is very low, and power savings is remarkable.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1 be according to the family expenses watt-hour meter control device that provides of the present utility model and with the circuit diagram of family expenses watt-hour meter annexation, accompanying drawing 2 is scheme of installations of energy-saving control device.

Family expenses watt-hour meter energy-saving control device as shown in drawings, a bidirectional triode thyristor BCR is arranged, electrode of this silicon controlled (being control output end (6)) is connected (promptly being connected with the control input end (3) of watt-hour meter) with the potential winding L2 of watt-hour meter (7), also have two end to end diode D1 and D2, the end of diode D1 is zero line output terminal (5), output terminal (5) is connected with the silicon controlled control utmost point, the other end of diode D1 is zero line input end (4), input end (4) serial connection capacitor C 2 links to each other with another electrode of silicon controlled again.Diode D1 and D2 are big electric current diode.
As shown in Figure 1, diode D1 capacitor C 1 also in parallel.
As shown in Figure 2, energy-saving control device (8) is installed on the table tail (12) of watt-hour meter.The mode of connection of former table tail (12) turnover live wire is constant, with two original zero lines, receive respectively on two binding posts (9) and (10) of energy-saving controller, a wiring hole is arranged in the middle of the energy-saving controller housing, pass this hole with screw (11) control device is fixed on the table tail, an end of screw (11) is screwed on the screw hole of table tail, and screw is a metallic screw, playing the effect that is connected between energy-saving control device and the watt-hour meter, is the terminals of meter voltage coil.
