Abstract
The utility model relates to an automatic transfer switch, in particular to an automatic transfer switch for triple power supplies, belonging to the field of an electric switch. The automatic transferswitch comprises a base, a first execution circuit breaker, a second execution circuit breaker and a controller arranged on the base, and is characterized in that the base is also provided with two AC contactors which are in mechanical interlocking; control ends of the two AC contactors are both connected with the controller; and load ends of the two AC contactors are connected at the incoming end of the second execution circuit breaker in parallel. The utility model utilizes the AC contactor to replace the automatic transfer switch for dual power supplies in the other group, so that the automatic transfer function of the triple power supplies is realized, the volume of the product is greatly reduced, and the cost is greatly lowered.
Description
Technical field
The utility model relates to a kind of automatic change-over, and particularly a kind of three-way power automatic change-over is to belong to the appliance switch field.
Background technology
Along with fail safe and reliability requirement to electric power system are more and more higher, automatic change-over is used in electric power system, hospital, post and telecommunications, fire-fighting, hotel, bank, airport, harbour, residential quarters, skyscraper, TV station, military installations, market etc. more and more and does not allow the important place that has a power failure.Need realize the power supply in turn of load is changed between three-way power by suitable transfer switch equipment with the three-way power electric power system in some important events.
Existing power supply three-way power electric power system, the automatic conversion of adopting two double power supply automatic transfer switchs to make up usually to realize three-way power (as accompanying drawing 1), its priority is a power supply 1, power supply 2, power supply 3.This its structure of three-way power automatic change-over is huger relatively, so the cost height.
The utility model content
The purpose of this utility model is to solve the deficiency of existing three-way power automatic change-over, and a kind of compact conformation, three-way power automatic change-over with low cost are provided.
The purpose of this utility model is achieved by the following technical solution: a kind of three-way power automatic change-over, include base, base-mounted first carries out circuit breaker, second carries out circuit breaker and controller, it is characterized in that: also be provided with two A.C. contactors that become mechanical interlocking on the described base, the control end of two A.C. contactors all is connected with controller, and the load end of two A.C. contactors is connected in the incoming end of the second execution circuit breaker in parallel.
The utility model is owing to substitute the double power supply automatic transfer switch of another group with A.C. contactor, thereby the auto-conversion function of realization three-way power has greatly reduced the volume of product, and cost reduces greatly.
Description of drawings

Fig. 2 is the structural representation of the utility model three power supply automatic change-over embodiment
Fig. 3 is the fundamental diagram of the utility model three power supply automatic change-over embodiment
Embodiment
Now in conjunction with the accompanying drawings execution mode of the present utility model is further described:
As shown in the figure, a kind of three-way power automatic change-over of the utility model embodiment, include base 1, be contained in first on the base 1 and carry out circuit breaker 2, second carries out circuit breaker 3 and controller 5, also be provided with two A.C. contactors 4 (so-called mechanical interlocking A.C. contactor is meant that two A.C. contactors add that mechanical interlocks combines) that become mechanical interlocking on the described base 1, the output of two A.C. contactors 4 (load end) is connected in the incoming end of the second execution circuit breaker 3 in parallel, first input of carrying out circuit breaker 2 connects power supply commonly used, normally closed control end control connection first stand-by power supply of the one A.C. contactor 4 of mechanical interlocking, another A.C. contactor often drive control end control connection second stand-by power supply.If power supply commonly used is lower than a rational value, controller sends the normally closed control end adhesive that instruction makes mechanical interlocking A.C. contactor 4, automatically switches to first via stand-by power supply (being generally another road transformer frequency response); If the second the tunnel has fault, controller sends instruction, and the normally closed control end of mechanical interlocking A.C. contactor 4 discharges, and (starter-generator also loads automatically) switches to Third Road power supply (the second tunnel stand-by power supply, normally generating set) automatically.Power supply commonly used is being judged always, in case after recovering, will switch back power supply commonly used.
