Problems solved by technology

[0002] The battery is the core of the DC system. With the increase of the operating life, individual batteries will inevitably have faults such as leakage, high resistance, and zero value. Currently, the faulty battery is replaced under the 1+1 DC power supply mode, because there is no special equipment. It will inevitably cause the battery pack to run off-line with the charger and the load, and the DC bus of the substation DC system cannot be disconnected from the battery pack at any time (operation, maintenance, inspection, AC power failure or power loss)

Abstract

The invention relates to a storage battery online replacement device. The storage battery online replacement device comprises an air switch I, a rectifier element, an air switch II, an electric current meter and a direct-current fuse which are connected in sequence through wires, the air switch I and the direct-current fuse are connected with a connector terminal respectively, two voltmeters are connected in parallel, one end of the voltmeters is connected to the input end of the rectifier element, and the other end of the voltmeters is connected to the output end of the direct-current fuse. According to the storage battery online replacement device, the situation of replacing a storage battery under the condition of supplying the electricity uninterruptedly becomes possible, the work reliability of a direct current system is enhanced, and the direct current system accidents are avoided.

Description

technical field [0001] The invention relates to a special equipment for construction work, in particular to an online storage battery replacement device, which is mainly used in the task of replacing a single bottle in various storage battery groups. Background technique [0002] The battery is the core of the DC system. With the increase of the operating life, individual batteries will inevitably have faults such as leakage, high resistance, and zero value. Currently, the faulty battery is replaced under the 1+1 DC power supply mode, because there is no special equipment. It will inevitably cause the battery pack to run off-line with the charger and the load, and the DC bus of the substation DC system cannot be effectively disconnected from the battery pack at any time (operation, maintenance, inspection, AC power failure or power loss). Contents of the invention [0003] The present invention aims at the problems existing in the above-mentioned prior art, and provides an...
