DC storage battery power supply system with on-line monitoring function for transformer station

Abstract

The invention discloses a DC storage battery power supply system with an on-line monitoring function for a transformer station, and the system comprises a power supply device, a monitoring alarm device and a storage battery online monitoring device. The power supply device is used for converting an alternating current into a direct current for charging a storage battery and supplying power to a DCload. The alarm monitoring device is used for monitoring the power supply device, and the storage battery online monitoring device is used for monitoring the working state of the storage battery in real time. The system achieves the integration of the charging of a DC system and the online monitoring of the storage battery, and the power supply for the charging of the DC system is flexible, wherein the capacitor of a charger can be adjusted flexibly. The system is provided with the reasonable monitoring alarm device, achieves the online monitoring of the condition of the storage battery, is more accurate and timely in data measurement, can achieve the advanced early warning, and reduces the manual maintenance burden. In addition, the storage battery online monitoring device achieves the online maintenance of the storage battery, and achieves the monitoring of the working environment of the storage battery.

Description

technical field [0001] The invention relates to the technical field of substation storage battery monitoring systems, in particular to a substation DC storage battery power supply system with an online monitoring function. Background technique [0002] The substation DC system is a very important secondary equipment in the substation. Its main task is to provide DC operating power for relay protection, switch opening, closing and control. Its normal operation or not is related to relay protection and Whether the switch can correctly remove the fault will also affect the normal operation of the whole station and even the upper substation. However, as the operating life of the DC system of the substation becomes longer and the equipment ages, the reliability of the DC power supply of the substation will be seriously affected. Therefore, the old DC system must be transformed. Due to the lack of ideal special equipment in the market during the replacement and transformation of ...

Problems solved by technology

This kind of degraded battery has great potential safety hazards, but the users and management units often only pay attention to the maintenance and management of the equipment part of the backup power supply, while ignoring the maintenance and monitoring of the battery. Little do they know that the danger of power failure is very large The above is due to the decline of the battery, because the battery is more likely to cause serious accidents such as fire and explosion after the battery declines.
