Abstract
The utility model discloses an automatic change-over switch for double-power which principally comprises an electro-magnetism control system, a machinery cut-over system and a drive shaft. Wherein, the electro-magnetism control system is provided with an intermediate relay and a shunt relay, and the both ends of each group of coils of the electro-magnetism control system are provided with a successor stream device. Based on the structure, the utility model can send the electrical signals to B power trip coils and A power closing coils simultaneously when the A power is switched on as well as send electrical signals to A power trip coils and B power closing coils when the B power is switched on via relays in the electro-magnetism control system without additional relays from the user. Moreover, the utility model has the advantages of reliable movement and small shock to the electric network, besides, the arrangement of successor stream device at the both ends of the coils further guarantees the dependability of action and reduces the back blast to the current converter, and the connection of the wire is simple for the user, the utility model can work only when the wire is connected.
Description
Technical field
The utility model relates to a kind of mains switch, refers to a kind of double power supply automatic transfer switch especially.
Background technology
Present used double power supply automatic transfer switch, its circuit as shown in Figure 1, it mainly comprises electromagnetic control system 1, machinery switched system 2, electromagnetic control system comprises control switch 11,12,15, the a-power supply side drops into terminal 13, a-power supply side tripping operation terminal 14, the B-source side drops into terminal 16, B-source side tripping operation terminal 17, auxiliary switch 21, during use, it can be by certain requirement (voltage, electric current, time, parameters such as frequency) at a-power supply, conversion back and forth between the B-source two-way power supply, this conversion is that (note is made A1 by a-power supply side input terminal 13, A2), (note is made BT1 to B-source side tripping operation terminal 17, BT2), the B-source side drops into terminal 16, and (note is made B1, B2), (note is made AT1 to a-power supply side tripping operation terminal 14, AT2) the energising that cooperatively interacts is finished, when a-power supply closes a floodgate, should give B-source side tripping operation terminal 17 signals earlier, finishing B-source threads off, drop into terminal 13 signals for again the a-power supply side, finish a-power supply and close a floodgate, finish whole translation function then; When B-source closes a floodgate, should give a-power supply side tripping operation terminal 14 signals earlier, finish a-power supply and thread off, drop into terminal 16 signals for again the B-source side, finish B-source and close a floodgate, finish whole translation function then; This change over switch, its switching time is longer; Complex circuit is out of order easily; In addition, the time of instant cut-off is longer; Moreover, if the product action is unreliable, then easily current converter is produced reverse impact, and change over switch generally all is applied in the place of outbalances such as building, hospital and airport radar tower, if the problems referred to above take place when switching, then consequence is hardly imaginable.
The utility model content
