Abstract
The utility model discloses an intelligent multi-power supply switch which comprises a multipath bidirectional controllable silicon changeover switch circuit; wherein, one input end of the multipath bidirectional controllable silicon changeover switch circuit is electrically connected with an external power supply jack; the other input ends are respectively and electrically connected with an external UPS power supply jack; the output ends of the multipath bidirectional controllable silicon changeover switch circuit share one power supply output terminal; the bidirectional controllable silicon control pole in each path is electrically connected with a drive control circuit through a separation drive circuit. The intelligent multi-power supply switch has the advantages that as bidirectional controllable silicon is adopted for switching power supply, the service life and switching speed are greatly improved so that the intelligent multi-power supply switch is applicable to situations requiring high switching speed; meanwhile, no sparkle exists during switching process and the influence on external environment is greatly reduced. When in operation, the drive control circuit analyzes the bidirectional controllable silicon changeover switch circuit signal in each path and then sends the control signal to the separation drive circuit for controlling the on and off states of the bidirectional controllable silicon.
Description
Technical field
The utility model relates to power transfer device, especially relates to multiple power supplies intelligence switch.
Background technology
Along with the development of society, a lot of communication apparatus require working power not to be interrupted, so uninterrupted power supply (ups power) arises at the historic moment.In order to guarantee the equipment reliability service, when civil power is normal, directly export to power devices by civil power, when civil power occurs when unusual, system breaks the power supply of civil power automatically, simultaneously ups power is outputted to power consumption equipment.Present employed ups power switch adopts relay to switch more, and noise was big when the deficiency of its existence was switch operating, speed is slow, and easily to produce spark, useful life short in the contact; Therefore for requiring switch speed height or explosion-proof occasion just to seem inapplicable.
The utility model content
The utility model purpose is to provide fast, the safe and reliable multiple power supplies of a kind of switch speed intelligent switch.
For achieving the above object, the utility model can be taked following technical proposals:
Multiple power supplies intelligence switch described in the utility model, it comprises multichannel bidirectional triode thyristor switching switch circuit; Wherein one road input in the described multichannel bidirectional triode thyristor switching switch circuit is electrically connected with external power supply socket, and all the other each road inputs are electrically connected with external ups power socket respectively; The public power output terminal of described multichannel bidirectional triode thyristor switching switch circuit output; The bidirectional triode thyristor control utmost point in every road is electrically connected with Drive and Control Circuit by isolated drive circuit respectively.
The utility model advantage is to adopt bidirectional triode thyristor to carry out the power supply switching, therefore useful life and switch speed (Millisecond) have been improved greatly, thereby satisfied the switch speed requirement than higher occasion, and when switching, do not had spark, reduced interference to external world greatly.During work, Drive and Control Circuit is analyzed each road bidirectional triode thyristor switching switch circuit signal, then control signal is delivered to isolated drive circuit, in order to the on off operating mode of control bidirectional triode thyristor.The utility model is in light weight simultaneously, the reliability height, and noise and external interference are little.
