Description
The utility model relates to the power supply source technical field of electricity, relates to a kind of alternating current steady voltage plug particularly and discerns load, on-off system automatically.
In the prior art, people are bigger for overcoming mains fluctuations, and the shortcoming of many household electrical appliance cisco unity malfunctions adopts miniwatt (100W-2000W) fully automatic pressure-stabilizing source usually.Though there is following shortcoming simultaneously in simple in structure, convenient feasible advantage that it has: the one, its open circuit loss is big, the waste power resource; The 2nd, it does not possess the function of automatic identification load, break-make, brings inconvenience etc. for people's use.Along with improving constantly and social development of living standard, people thirst for that appearing on the market of a kind of novel voltage stabilizing power supply can be arranged, to satisfy the demand of its life.
The purpose of this utility model provides a kind of alternating current steady voltage plug and discerns load, on-off system automatically, and it did not both waste, and saves energy has easy to usely again, saves time, to satisfy people's life requirement.
The purpose of this utility model is by the structural design scheme of automatic identification load, on-off system is realized.Its device is by diode D

1Three terminal circuits that series connection back three's parallel connection and bidirectional triode thyristor BCR constitute are so it has structural design novelty, reasonable and simple; Simultaneously because it is highly sensitive, safe and reliable, thus its both loss-free, saves energy resource, remarkable in economical benefits; Easy to use again, save time.Be its wide adaptability again, it adopts in the circuit of single-circuit transformer output voltage formula applicable to all.Be a kind of comparatively desirable novel voltage stabilizing power supply, satisfy people's living needs, improved its quality of life; Market potential is big, is suitable for the whole society and popularizes.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the fundamental diagram of the automatic identification load that the utility model proposes, on-off system (in the frame of broken lines).
Describe in detail according to the automatic identification load that the utility model proposes, the details and the working condition of on-off system below in conjunction with accompanying drawing 1.
This device is connected in the input supply terminal point 1 of mu balanced circuit, between the elementary winding of out-put supply end points 3 and transformer.The parameter stable voltage source for TV output power of each element in its circuit and deciding.In the present embodiment, the output power of stabilized voltage supply is 300W, D

4Be 2A commutator tube, resistance R
1Be 30-100 Ω, capacitor C is 0.66uf, and bidirectional triode thyristor BCR is 2A.When in the circuit when three terminal A, B, C short circuit, be a kind of common mu balanced circuit that uses in the market product.Its course of work is as follows:
When the output terminal 3,4 of stabilized voltage supply, when not connecing load, though its input end 1,2 has 220 volts of alternating voltage inputs, BCR ends because of controllable silicon, and electric current does not have the loop, and power supply is not worked.After when output terminal 3,4 connects load, the alternating current of input end is by diode D

4Through load and relay contact JK
1And transformer portion winding formation current return, and at 2 generations of A, B sampled voltage more than 1 volt, this voltage is through resistance R
1The current limliting lotus root is closed, and triggers controllable silicon BCR conducting, makes power supply enter normal voltage stabilizing duty.
When input voltage was low, transformer T secondary winding voltage was lower, relay J
