Abstract
The utility model relates to an intelligent type dual-power automatic change-over switch characterized in that: a leading-out end of a common-used power supply is connected with a motor and a first breaker, a leading-out end of a stand-by power supply is connected with the motor and a second breaker; a display panel is arranged between a relay and the motor; leading-out ends of the first breaker and the second breaker are connected with a load; the relay is arranged between the common-used power supply and the stand-by power supply; an interlocking device is arranged between the first breaker and the second breaker; and the interlocking device comprises a mechanical interlocking device and an electrical interlocking device. Compared with the prior art, the intelligent type dual-power automatic change-over switch of the utility model can set parameters externally, may have lower energy consumption, and adopts a dual interlocking protection, thus the intelligent type dual-power automatic change-over switch can be safer and more reliable, and has a good implementation effect.
Description
Technical field
The utility model relates to a kind of change over switch, particularly a kind of intelligent duplicate power supply automatic change-over.
Background technology
Existing dual-power transfer switch is made up of one or more change over switches and other essential electrical equipment, is used to detect power circuit, and with the automatic transfer equipment of one or more load circuits from power source conversion to another power supply.When having the situation of power supply commonly used and two power supplys of stand-by power supply; Switch should be specified a position of source commonly used; Its operation sequence is made up of two automatic transfer processes, if power supply commonly used is detected when deviation or fault occurring, then automatically with load from power source conversion commonly used to stand-by power supply.Existing double-power supply switching device, it is easy to generate misoperation, and it is unreliable to interlock, and energy consumption is big, can not satisfy actual needs.
Summary of the invention
The deficiency that the utility model exists to prior art just provides a kind of intelligent duplicate power supply automatic change-over.The described intelligent duplicate power supply automatic change-over of the utility model; The exit of power supply commonly used is connected with the motor and first circuit breaker; The exit of stand-by power supply is connected with the motor and second circuit breaker, between relay and motor, is provided with display floater, and the exit of first circuit breaker and second circuit breaker is connected with load; Be provided with relay between described power supply commonly used and the stand-by power supply, between first circuit breaker and second circuit breaker, be provided with interlock.
Described interlock comprises mechanical interlocks and electric interlocking installation.
The described intelligent duplicate power supply automatic change-over of the utility model, compared with prior art, its parameter can externally be set, and energy consumption is lower, and takes the dual interlock protection, and more safe and reliable, implementation result is good.
Description of drawings
Fig. 1 is the described intelligent duplicate power supply automatic change-over of a utility model mounting structure sketch map;
Wherein:
1-power supply commonly used, 2-stand-by power supply, 3-relay, 4-motor, 5-interlock, 6-the first circuit breaker, 7-the second circuit breaker, 8-load, 9-display floater.
Embodiment
To combine concrete embodiment that the content of the utility model is described below.
As shown in Figure 1, be the described intelligent duplicate power supply automatic change-over of the utility model mounting structure sketch map.Be provided with relay 3 between power supply 1 commonly used and the stand-by power supply 2.The exit of power supply 1 commonly used is connected with the motor 4 and first circuit breaker 6.The exit of stand-by power supply 2 is connected with the motor 4 and second circuit breaker 7.Between relay 3 and motor 4, be provided with display floater 9.Between first circuit breaker 6 and second circuit breaker 7, be provided with interlock 5.The exit of first circuit breaker 6 and second circuit breaker 7 is connected with load 8.
The described interlock 5 of the utility model comprises mechanical interlocks and electrical equipment interlock, and wherein electrical interlock is the intelligent electric interlocking of core by the MOTOROLA single-chip microcomputer, and duplicate protection is provided like this, and is more safe and reliable.
During operate as normal, by power supply 1 normal power supply commonly used, this moment first circuit breaker 6 closures, second circuit breaker 7 breaks off, display floater 9 demonstrates corresponding state, supplies power for load 8 by power supply 1 commonly used like this.When power supply 1 commonly used breaks down, as producing overvoltage, under-voltage, phase shortage etc. when unusual, judge by relay 3 samplings, relay 3 action triggers motor 4 runnings in setting-up time, and then drive interlock 5 state variation.This moment first, circuit breaker 6 broke off, and second circuit breaker, 7 closures give load 8 power supplies by stand-by power supply 2, and the related work state shows on display floater 9.
The described intelligent duplicate power supply automatic change-over of the utility model, compared with prior art, its parameter can externally be set, and energy consumption is lower, and takes the dual interlock protection, and more safe and reliable, implementation result is good.
