Abstract
The utility model relates to a direct current UPS (uninterrupted power supply), which includes a battery charger and a chargeable battery; one end of the battery charger is connected with a power gird, the other end is connected with the chargeable battery at a node a, which is connected with a generator control system, and a convertor is arranged between the node a and the generator control system. The utility model solves the technical problem that the DC power supply of the existing generator is easy to damage the generator control system, and provides a direct current UPS that can not only charge the chargeable battery but also can guarantee the rated voltage of an electric motor, and the service life of the chargeable battery in the power supply is prolonged.
Description
Technical field
The utility model relates to a kind of power supply, especially a kind of DC UPS that is applied to generator powered.
Background technology
The power supply of existing generator is generally by the battery charger that is connected with electrical network, rechargeable battery and D.C. regulated power supply constitute, when electrical network has electric power, power to motor by D.C. regulated power supply by electrical network, when the electrical network unregulated power, power to motor by the contact of battery charger and rechargeable battery by rechargeable battery, because the power supply rated voltage of motor is generally 24V, and battery charger is when charging to rechargeable battery, for guaranteeing that rechargeable battery can be full of, the voltage (generally about 29-30V) that need be higher than 24V charges, if but adopt high-voltage charging, then when electrical network has electric power, become electrical network to power to motor by the contact of battery charger and rechargeable battery, this moment, voltage was higher than 24V, damaged generator control system easily, if and only charge to rechargeable battery with the voltage of 24V, then battery is in the underfill state for a long time, and rechargeable battery is scrapped easily, can reduce the useful life of rechargeable battery.
The utility model content
The utility model can be full of electricity for the above-mentioned technical problem that the DC power supply that solves the generator in the background technology exists to rechargeable battery and provide a kind of, can guarantee the DC UPS of the rated voltage of motor power supply again.
Technical solution of the present utility model is: the utility model is a kind of DC UPS, comprise battery charger, rechargeable battery, battery charger one end is connected with electrical network, the other end is connected to node a mutually with rechargeable battery, node a and generator control system join, and its special character is: be connected to transducer between described node a and the generator control system.
Above-mentioned DC UPS also comprises D.C. regulated power supply, and D.C. regulated power supply one terminates on the electrical network, and the other end is connected to node b mutually with generator control system, and transducer is connected between node a and the node b.
Above-mentioned D.C. regulated power supply parallel connection is two.
Above-mentioned D.C. regulated power supply joins by unilateral diode and generator control system.
Above-mentioned transducer joins by unilateral diode and generator control system.
Above-mentioned transducer is the DC/DC transducer.
The utility model is at the contact of battery charger and the rechargeable battery DC/DC transducer of connecting with the contact between stabilized voltage power supply and the generator control system, utilize the characteristics of DC/DC transducer: input voltage is in the excursion of regulation, output voltage maintains high-precision rated voltage output, can guarantee that like this battery charger can charge to rechargeable battery by high pressure, whether can detect the rechargeable battery state is full of, in the time of also can guaranteeing that electrical network has electric power, only power to generator control system by D.C. regulated power supply, guarantee the rated voltage of generator control system power supply by electrical network; Also guaranteed the requirement of the voltage stabilizing power supply that generator control system starts when electrical network and generator all do not have electricity, simultaneously the utility model on the basis of existing traditional D.C. regulated power supply multi-parallel one road D.C. regulated power supply, to guarantee under the situation that certain road D.C. regulated power supply damages, can replace working on by another road, be equivalent to back up one road D.C. regulated power supply more, further guarantee the stability of power supply power supply.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model DC/DC transducer 5 of between the contact b between the contact a of battery charger 1 and rechargeable battery 4 and D.C. regulated power supply 2 and the generator control system 3, connecting, utilize the characteristics of DC/DC transducer 5: input voltage is in the excursion of regulation, output voltage maintains high-precision rated voltage output, make the input voltage of DC/DC transducer 5 can reach 35V, be stabilized in 24V and will export electricity, can guarantee that like this battery charger 1 can be higher than the charging curve of 24V voltage to rechargeable battery 4 chargings, whether can detect the rechargeable battery state is full of, and be full of the back charger and stop charging automatically, in the time of also can guaranteeing that electrical network has electric power, only give generator control system 3 power supplies by D.C. regulated power supply 2 by electrical network, guarantee the rated voltage of generator control system 3 power supplies, and D.C. regulated power supply 2 joins by unilateral diode 7 and generator control system 3, transducer 5 joins by unilateral diode 6 and motor, to guarantee D.C. regulated power supply 2 and transducer 5 forward conductions, oppositely not conducting; Simultaneously the utility model on the basis of existing traditional D.C. regulated power supply multi-parallel one road D.C. regulated power supply, to guarantee under the situation that certain road D.C. regulated power supply damages, can replace working on by another road, be equivalent to back up one road D.C. regulated power supply more, further guarantee the stability of power supply power supply.When the electrical network unregulated power, the contact a by battery charger 1 and rechargeable battery 4 powers to generator control system 3 by rechargeable battery 4.
