Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an uninterruptible power supply system includes a utility power supply, a first storage battery, a second storage battery, and a switching device. The commercial power is used for supplying power to a load; the first storage battery is used for supplying power to a load after the mains supply is powered off; the second storage battery is used for supplying power to the load after the mains supply is powered off; the switching device can switch a circuit in the system after the mains supply is cut off so that the first storage battery or the second storage battery supplies power to the load; the commercial power can charge the first storage battery and the second storage battery when normal so that the first storage battery and the second storage battery are kept in a full-charged state.
As shown in fig. 2, the switching device includes: commercial power contact 1, first contact 2 and second contact 3 and switching contact 4. The mains supply contact sheet 1 is connected with mains supply; the first contact piece 2 is connected with a first storage battery; the second contact piece 3 is connected with a second storage battery; the switching contact piece 4 makes the commercial power or the first storage battery or the second storage battery supply power for the load through contacting with the commercial power contact piece 1 or the first contact piece 2 or the second contact piece 3.
The middle part of switching contact 4 rotates to be connected on first branch 5, and the both ends of switching contact 4 are provided with left contact 6 and right contact 7 respectively, and the one side that lies in first branch 5 in the plane that switching contact 4 rotated is provided with first contact 2, and opposite fixity is provided with commercial power contact 1 and second contact 3 from top to bottom from the opposite side. First contact 2 middle part is rotated and is connected on second branch 9, second contact 3, the rotation tie point of switching contact 4 and first branch 5, commercial power contact 1 are in addition these four positions of the rotation tie point of first contact 2 and second branch 9 are arranged according to order from high to low in the direction of height, and the vertical distance between commercial power contact 1 and the second contact 3 is greater than the vertical distance that switches between contact 4 rotation tie point to the first contact 2 rotation tie point.
Commercial power supply enables the commercial power rotation source 10 to have a movement trend of driving the switching contact piece 4 to rotate so that the right contact 7 approaches the commercial power contact piece 1 and contacts with the commercial power contact piece 1. The commercial power rotation source 10 includes a first core 11 and a first coil 12. First iron core 11 is fixed to be set up in switching one side that is close to commercial power contact 1 in contact 4 below, and wherein, first coil 12 is around establishing in first iron core 11 outside, and first coil 12 can switch on by the commercial power supply, and when the commercial power circular telegram, the electric current in first coil 12 can form the magnetic field that can attract switching contact 4 at first iron core 11 tip, makes switching contact 4 rotate and makes right contact 7 and commercial power contact 1 contact.
The first reset piece 13 always has a movement trend of driving the switching contact piece 4 to rotate reversely so that the right contact 7 is contacted with the commercial power contact piece 1 to the second contact piece 3. The first reset piece 13 is a spring, the spring is arranged on one side, close to the first contact piece 2, below the switching contact piece 4, the spring always has a pulling force which is the same as the commercial power rotation source 10 in the direction of the suction force of the switching contact piece 4, and the suction force is larger than the pulling force.
As shown in fig. 3, when the mains supply is disconnected, the current in the first coil 12 disappears to make the end of the first iron core 11 have no attraction, and at this time, the first reset piece 13 drives the switching contact 4 to rotate reversely to move the right contact 7 from the contact with the mains supply contact 1 to the contact with the second contact 3.
When the right contact 7 of the switching contact piece 4 is at a certain position between the commercial power contact piece 1 and the second contact piece 3, the left contact 6 of the switching contact piece 4 is in contact with the first contact piece 2, and the switching contact piece 4 can be stopped to continue rotating under the action of the first storage battery rotating source 14 so as to prevent the right contact 7 from being in contact with the second contact piece 3, and only when the first storage battery is not charged, the contact between the left contact 6 and the first contact piece 2 is removed, and the switching contact piece 4 can continue rotating to enable the right contact 7 to be in contact with the second contact piece 3.
A first storage battery rotation source 14 and a second reset piece 15 are respectively arranged on two sides of the second support rod 9 in the plane where the first contact piece 2 rotates. The first battery energizing force causes the first battery rotation source 14 to have a tendency to drive the first contact 2 to rotate so that the right end is closer to the switching contact 4 and contacts the left contact 6, and the second reset element 15 has a tendency to drive the first contact 2 to rotate in the opposite direction so that the right end of the first contact 2 is farther from the path of rotation of the left contact 6 of the switching contact 4.
The first battery rotation source 14 includes a second core 16 and a second coil 17. The second iron core 16 is fixedly arranged on one side, far away from the switching contact 4, below the first contact 2; the second coil 17 is wound outside the second iron core 16, the second coil 17 is powered and conducted by the first storage battery, and when the first storage battery is electrified, the current in the second coil 17 forms a magnetic field capable of attracting the first contact piece 2 at the end part of the second iron core 16. The second piece that resets 15 is the spring, and the spring setting is in the one side that first contact 2 below is close to switching contact 4, and the spring has the pulling force the same with first battery rotation source 14 to first contact 2 suction direction all the time to first contact 2, and the suction is greater than the pulling force.
When the first storage battery is electrified, the first storage battery rotation source 14 and the second reset piece 15 work together to enable the right end of the first contact piece 2 to be on the rotation path of the left contact 6 of the switching contact piece 4. When the mains supply is cut off, the switching contact piece 4 rotates reversely to enable the right contact 7 to contact with the right end of the first contact piece 2 from the contact with the mains supply contact piece 1 to move towards the contact direction with the second contact piece 3, and therefore the first storage battery supplies power for the load.
When the first battery is also de-energized, as shown in fig. 4, and the current in the second coil 17 disappears to make the end of the second core 16 have no attraction force, the second reset piece 15 drives the first contact piece 2 to rotate reversely to move the right end from contacting the switching contact piece 4 to a direction away from the left contact 6 of the switching contact piece 4.
At this time, the left contact 6 of the switching contact 4 continues to rotate without the obstruction of the first contact 2, so that the right contact 7 moves towards the direction of contacting with the second contact 3 until contacting with the left end of the second contact 3, and thus the second storage battery supplies power for the load.
The suction force of the commercial power rotating source 10 to the switching contact 4 is greater than the sum of the suction force of the first storage battery rotating source 14 to the first contact 2 and the suction force of the first resetting piece 13 to the switching contact 4. That is, when the first battery supplies power to the load, if the mains supply is restored to power on, the switching contact piece 4 resists the upward jacking force of the first contact piece 2 on the left contact 6 under the action of the suction force of the mains supply rotation source 10, so that the right end point of the switching contact piece 4 rotates downward to be in contact with the mains supply contact piece 1, and the power supply of the mains supply to the load is restored.
Through the arrangement of the switching device, the system can be switched among three power supplies uninterruptedly, and accidents or property loss caused by the fact that the mains supply is cut off and the power supply cannot be supplemented immediately can be prevented.
As shown in fig. 1, the first storage battery and the second storage battery are further connected to a periodic discharging device, respectively, and the periodic discharging device can periodically and alternately discharge the first storage battery and the second storage battery. The periodic discharge device comprises a periodic device and a discharge device. The time for requiring the storage battery to discharge periodically is preset in the periodic device; the discharging device is used for consuming electric energy in the storage battery to discharge the storage battery.
If the mains supply is not stopped for a long time, the system actively and automatically discharges the batteries properly at intervals, which is beneficial to activating the storage batteries, so that the service life of the batteries can be prolonged; in addition, the two storage batteries are used for alternately discharging, so that the mains supply is prevented from being suddenly cut off when the storage batteries are discharged, and the uninterruptible power supply system is prevented from being powered off.
As shown in fig. 1, when the switching device switches to enable the first storage battery or the second storage battery to supply power to the load, the alarm device gives an alarm to prompt timely charging, and the alarm device is arranged in a circuit for supplying power to the load by the first storage battery and the second storage battery.
