Output end.
As a preference, further include adjusting knob, the corresponding resistance value for adjusting the adjustable resistance of the adjusting knob.
As a preference, the lead-in clamp and output wiring terminal are equipped with the red blue mark for indicating positive and negative anodes
Know.
The beneficial effects of the utility model are:
1, the quick connection and replacement of storage batteries of transformer substation are realized.The battery of the auxiliary device never failure directly takes
Electricity is forwarded to the battery both ends of failure.The quick connection for realizing power supply device and battery, quickly replaces unqualified electric power storage
Pond.
2, input voltage is adjustable, suitable for taking electricity from the battery of different number or specification.
3, output voltage is adjustable.Equipped with multiple output gears, plural number battery can be replaced simultaneously.
4, it improves efficiency, it is easy to carry, it is easy to operate, save manpower.Only need a people that the operation of replacement battery can be realized,
And heavy reserve battery is not needed to carry, effectively increase working efficiency.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But a kind of change of the utility model
Battery replacement auxiliary device in power station is not limited to the embodiment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment:
Shown in Figure 1, the technical solution of the utility model is specific as follows:
Battery replaces the external structure of auxiliary device as shown in Figure 1, specifically including such as lower component: (1) lead-in clamp 3
With output wiring terminal 4；(2) DC/AC power supply；(3) display screen 6；(4) air switch 5；(5) voltmeter 2；(6) adjustable resistance；(7)
AC/DC converter.
Internal circuit configuration is as follows:
The output end of the DC/AC power supply is electrically connected with the AC/DC converter, the output end of the AC/DC converter
It altogether include tri- gears of 6.9V, 9.2V and 12.5V；The input terminal of the adjustable resistance, the air switch and DC/AC power supply is mutual
Mutually it is connected in series, the input voltage of the voltmeter detection display DC/AC power supply.The DC/AC power supply and AC/DC converter are realized
The power supply situation conversion of DC/AC/DC, while the DC circuit of input terminal and output end is mutually isolated, will not be because of taking
The position of electricity is formed into a loop with power output end and causes to be shorted.
This project purpose is to provide unqualified battery replacement auxiliary device in a kind of auxiliary substation, is used to replace completely
The function of standby battery.The power supply device is the device of a DC/DC (DC to DC), and existing storage battery in transformer substation group has
103 or 104 batteries, when unqualified battery is a certain section in No. 1-52, then the power supply device from the anodes of No. 53 batteries with
Power supply (voltage about 110V) is taken between the cathode of No. 104 batteries；When unqualified battery is a certain section in No. 53-104, then should
Power supply device takes power supply (voltage about 110V) between the anode of No. 1 battery and the cathode of No. 52 batteries.Power supply device it is defeated
Voltage is adjustable out, and total voltage when being connected in series with three sections, four sections or five section standby batteries is close.The power supply device is defeated
Entering power supply and out-put supply using transformer isolation, then output end can be parallel at two batteries of front and back of unqualified battery, into
The replacement of row unqualified battery.The power supply device passes through the design of internal power electronic control circuit, is about 110V input
Direct current be converted into three kinds of optional direct currents that voltage is about 6.9V, 9.2V or 12.5V, centre realize input power with
The isolation of out-put supply.
The replacement power accessories have following functions:
