Description
Technical field
The utility model relates to one and automatically identifies supply voltage, automatically accesses the twin voltage high efficiency single-phase asynchronous motor of different electromagnetic parameter according to voltage levels.
Background technology
Monopole asynchronous motor because be not received by the market by three phase mains restriction very much.By normal rule, general motor is all according to normal supply power voltage standard design electromagnetic parameter, usually require when voltage fluctuation positive and negative 10%, enough torques can be ensured.
Along with the development of society, consuming device constantly increases, and power supply capacity does not often catch up with the speed of the increase of power consumption, thus causes supply voltage on the low side, and then causes generation motor operation properties to reduce the phenomenon even can not normally run.
Summary of the invention
The purpose of this utility model, is to provide one and automatically identifies supply voltage, automatically accesses the twin voltage high efficiency single-phase asynchronous motor of different electromagnetic parameter according to voltage levels.
Realize the technical solution of the utility model as shown in Figure 1, the main winding designed by normal voltage [LZ] is drawn tap [B], by driving the changeover contact of relay [J] by power supply voltage monitoring switching circuit [DK], access whole main winding (high pressure A ~ C) when supply voltage is normal; When supply voltage is on the low side, the coil sections (low pressure B ~ C) of conversion access main winding.
About the monitoring switch circuit of supply voltage, there are many common prior aries at will to select, as long as according to supply voltage height, determine whether to drive the actuating of relay, select which kind of circuit all among the rights protection scope of the technical program.
The utility model is particularly suitable for the occasion in power supply capacity relative deficiency, and the larger capacity motor of use reliably can start normal operation under very low voltage.
accompanying drawing explanation:
Fig. 1 is the circuit diagram of the twin voltage high efficiency single-phase asynchronous motor automatically accessing different electromagnetic parameter according to voltage levels.
Fig. 2 is the complete circuit of a specific embodiment.
Each map logo is unitedly described as follows:
LZ is main winding, and wherein A and C is respectively its two-end-point, and B is middle tap; LF is auxiliary winding; QC is start-up capacitance; YC is running capacitor; LK is centrifugal switch; J is relay; DK in square frame represents the assembly of supply voltage monitoring switch circuit; ~ be power supply symbol; R1, R2 are divider resistance; ZQ1, ZQ2 are the rectifier bridge be made up of rectifying tube; WY is voltage-stabiliser tube; RS and CS forms rc-delay circuit; GO is photoelectronic coupler.
embodiment:
A kind of monitoring switch circuit specific embodiment of supply voltage is introduced below in conjunction with Fig. 2:
Monitored supply voltage is after resistance R1, R2 dividing potential drop, by the direct voltage of ZQ1 rectification, one tunnel is supplied to 8 pin of 555 circuit by the voltage that voltage-stabiliser tube WY is stable, another road feeding 2 and 6 pin point in parallel, 2,6 pin voltages higher than 8 pin voltages 2/3 time, 3 pin output low levels, relay J is failure to actuate, whole coils (A ~ C point) of plant-grid connection motor main winding LZ; 2,6 pin voltages lower than 8 pin voltages 1/3 time, 3 pin export high level, through the action of light even GO isolation drive relay J, power supply accesses motor main winding through tap (B), because the main winding reactance decreasing the number of turns reduces, ensure that the current values under low-voltage, the power of low-voltage is guaranteed.
Due to the effect of rc-delay circuit RS, CS, do not work immediately when power supply has just started place in circuit, terminate just to enter monitoring translation function after 4 pin level raise in time delay, its role is to the start-up course avoiding motor.
