Abstract

The invention discloses a device for replacing a single storage battery in a direct current system. The device comprises a diode, a fuse, a positive terminal, a negative terminal, a first iron clamp and a second iron clamp. The cathode of the diode is connected with the first iron clamp through the negative terminal, the anode of the diode is connected to the first end of the fuse, and the second end of the fuse is connected with the second iron clamp through the positive terminal; when the positive electrode of the fault storage battery is connected to the negative electrode of the first storage battery, the first iron clamp is connected to the negative electrode of the first storage battery; when the negative electrode of the fault storage battery is connected to the positive electrode of the second storage battery, the second iron clamp is connected to the positive electrode of the second storage battery. The applicant finds that the voltage change between the first storage battery and the second storage battery has directivity before and after the faulty storage battery is dismounted, so that the single faulty storage battery is replaced by utilizing the unidirectional conduction characteristic of the diode without exiting the whole group of storage batteries from the direct current system; therefore, the technical problems of high operation cost and low working efficiency in the prior art are solved.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a device for replacing a single storage battery in a DC system. Background technique [0002] In power plants and substations, the DC system provides reliable DC power for control signals, relay protection, automatic devices, and circuit breaker tripping and closing operation circuits. The DC system is generally composed of charging equipment, battery packs, and DC screen insulation monitoring devices. . Affected by factors such as materials, structure, and operating environment, the capacity of the battery will decrease after a period of operation and cannot be recovered or even malfunction, which seriously threatens the safe and reliable operation of the DC system and even the substation. According to the relevant regulations of the national electric power industry standard, at this time, a single battery or a whole group of batteries must be replaced without...
