Embodiment 1

[0073] Replace the damaged battery No. 3, whose circuit wiring is as follows Figure 4 shown.

[0074] Turn on the power switch of the meter before use, and connect the "+" and "-" terminals of the battery freewheel to the negative terminal of the upper adjacent battery 2-1 adjacent to the battery 3 to be replaced and the lower adjacent battery 2 respectively. -2 positive terminal, at this time, the aforementioned "the positive / negative electrode of the battery to be replaced and its adjacent battery" is the negative pole of the upper adjacent battery 2-1 connected to the battery 3 negative pole to be changed and the positive pole of the battery to be changed Connect the positive pole of the lower adjacent battery 2-2.

[0075] At this time, for the entire battery pack circuit, the battery freewheel connected in parallel is equivalent to an equivalent resistance of about 2 ohms connected in parallel, and the current flowing through the equivalent resistance can be read from th

Embodiment 2

[0079] Replace the battery connection bar 32 between the upper adjacent battery 2-1 and the lower adjacent battery 2-2 or repair / maintain the battery fastening screw 31, the circuit wiring of which is as follows Figure 4 shown.

[0080] Turn on the meter power switch before use, and connect the "+" and "-" terminals of the battery freewheel to the positive pole of the lower adjacent battery 2-2 and the negative pole of the upper adjacent battery 2-1 respectively. At this time, the aforementioned "The positive / negative electrodes of the battery to be replaced and its adjacent battery" are the negative pole of the upper adjacent battery 2-1 and the positive pole of the lower adjacent battery 2-2.

[0081] At this time, it is equivalent to adding a voltage of 4 volts to the connected battery freewheel, and the ammeter shows that the flowing current is 2 amperes.

[0082] When the storage battery connection bar 32 between the upper adjacent storage battery 2-1 and the lower adj

Abstract

The invention relates to a method and a device for preventing a direct-current system of a power transformation and distribution substation from powering off during storage battery maintenance, belonging to the field of direct-current power supplies. The method comprises the following steps of: connecting a storage battery current relay between the anode and the cathode of a storage battery adjacent to the storage battery to be replaced to structure a direct-current bypass loop; making the charging/discharging current of a storage battery pack of the direct-current system circulate in the storage battery to be replaced by using the storage battery current relay; replacing the storage battery to be replaced; and after finishing the maintaining work, removing the electrical connection between the storage battery current relay and the storage battery loop, thereby ensuring that the original circulating loop of the charging current or discharging current of the storage battery pack of the direct-current system of the power transformation and distribution substation is recovered. The method and the device ensure continuous power supply to a secondary loop system in the process of processing the defects of the storage battery, improve maintenance working efficiency, are also convenient for maintainers to timely master the working conditions of the direct-current system, and can be widely used in the overhauling/maintaining field of direct-current power supply devices in an electric transformation and distribution system.
