Description
Technical field
The utility model discloses a kind of dual power supply system of isolating, belong to storage battery isolation technology field based on storage battery.
Background technology
At present, the normal single power supply that adopts on the engineering machinery, the battery terminal negative bonding is controlled positive pole through power supply relay.But along with system becomes increasingly complex, power consumption equipment increases gradually, and often the consumption excessively of electric energy can cause machine not start.Generator can not be controlled the charging of storage battery; Mainly be the generating voltage of comparison generator and the voltage of storage battery; As long as the charging repeatedly that the voltage of storage battery will not stop less than the voltage of generator always; And in charging process, also have the influence of peak voltage, seriously shortened the useful life of storage battery.
Summary of the invention
In order to solve the problem that exists in the above-mentioned technology, the utility model discloses a kind of dual power supply system of isolating based on storage battery, can keep apart charging system and storage battery, reduce discharging and recharging number of times, improve the useful life of storage battery.
In order to achieve the above object; The utility model provides following technical scheme: a kind of dual power supply system of isolating based on storage battery, comprise main battery, boosting battery, generator and power supply relay, and main battery is parallelly connected with boosting battery; The two minus earth; Also comprise the storage battery isolation controller, storage battery isolation controller one end and main battery and boosting battery positive pole are electrically connected, and the other end and generator and power supply relay are electrically connected;
As preferably, the end points 87 or 30 of storage battery isolation controller and power supply relay is electrically connected.
Operation principle: adopt the storage battery isolation controller to isolate duplicate supply, when consumed power arrives set point, isolate main battery and boosting battery, just consume the electric energy of boosting battery, main battery has enough voltage when guaranteeing machine startup; When battery tension is reduced to set point, just charge, and main battery is preferential charging to have only main battery to be full of electricity, just comes in the boosting battery parallel connection to charge, when the charging system accumulators is full of electricity, can keep apart charging system and storage battery.
The beneficial effect of the utility model is: native system not only can provide enough starting resistors to system all the time, reduces to discharge and recharge number of times, can also prolong the useful life of storage battery.
Description of drawings
Fig. 1 is the utility model overall structure sketch map.
Among the figure: 1, main battery 2, boosting battery 3, storage battery isolation controller 4, power supply relay 5, key switch 6, starting relay 7, starter 8, generator.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, this is made up of main battery 1, boosting battery 2, storage battery isolation controller 3, power supply relay 4 and generator 8 based on the dual power supply system that storage battery is isolated; Main battery 1 has constituted duplicate supply with boosting battery 2, supplies power the two minus earth with parallel form; Positive pole all is electrically connected with storage battery isolation controller 3, has realized the isolation between main battery 1 and the boosting battery 2 like this, and the end points 87 of an other end of storage battery isolation controller 3 and generator 8 and power supply relay 4 is electrically connected simultaneously; Generator 8 other end ground connection, the coil end points 86 of power supply relay 4 is electrically connected coil end points 85 ground connection of power supply relay 4 with the terminal B R of key switch 5; Key switch 4 powers on; Coil gets electric, power supply relay 4 closures, and system gets.The end points 30 of power supply relay 4 is electrically connected with the end points 30 of starting relay 6; The end points 87 and the starter 7 of starting relay 6 are electrically connected, the other end ground connection of starter 7, and the coil end points 86 of starting relay 6 is electrically connected with the end points C of key switch 5; Another end points 85 ground connection of the coil of starting relay 6; When key switch 5 is got to end points C, main battery 1 power supply, starter 7 is accomplished and is started.Drive generator 8 and form electric power systems, earlier main battery 1 is charged, be full of electricity after, incorporate boosting battery 2 into system and charge.
