Description
Technical Field
The utility model relates to a battery monitoring field, concretely relates to battery trouble on-line monitoring system.
Background
A dc system of a substation is a power supply device for supplying a dc power supply to the operation and operation of various devices, is an indispensable part in the construction of the substation, and is mainly used for emergency lighting, automation devices, signal devices, switch control, system monitoring, and the like. Since the dc system of the substation is a power supply existing as a backup system, the operation mode of the substation power supply system does not affect the dc system. In a transformer substation, an alternating current power supply system is mainly used as a daily power supply network, the direct current power supply system can provide an important operating power supply and a standby power supply for the transformer substation, and if the transformer substation has a fault problem, the direct current power supply system becomes an important guarantee for the operation of the transformer substation and is the second heart of the transformer substation. Therefore, the detection and online monitoring of the substation battery is extremely important.
When the storage battery enters a high-voltage charging area when the charge capacity of the storage battery reaches about 80%, oxygen is firstly separated out on the positive plate and reaches the negative electrode through the holes in the partition plate, oxygen revival reaction is carried out on the negative plate, and heat can be generated in the reaction process. When the charge capacity reaches 90%, the generation rate of oxygen increases, and the negative electrode starts to generate hydrogen. The increase of a large amount of gas enables the internal pressure of the storage battery to exceed the valve opening pressure, the safety valve is opened, the gas escapes, and finally water loss is shown. After dehydration, the superfine glass fiber separator in the storage battery shrinks to cause the adhesive force between the superfine glass fiber separator and positive and negative plates to be poor, the internal resistance is increased, the heat productivity is increased in the charging and discharging process, when the heat dissipation capacity of the battery is smaller than the heat productivity, the temperature will rise, and finally the thermal runaway phenomenon is formed to cause deformation, the deformation of the battery is not completely caused by the internal chemical change, the battery can also be deformed due to the interference of some external force, and the judgment of a worker on the battery fault is easily confused.
The traditional battery fault monitoring system usually adopts an internal resistance testing method, a plurality of storage batteries are often used in a group in industry, when the internal resistance of the whole storage battery is monitored, the position of the fault storage battery cannot be directly determined, and when all the storage batteries are monitored one by one, more monitoring devices are needed, so that the cost is increased.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
The embodiment of the utility model provides a:
as shown in fig. 1-2, an online battery fault monitoring system includes a battery fixing plate 1, an infrared distance and temperature measuring module 20, an adjusting device 2, an internal resistance monitoring system, a background data processing control system, and an alarm device, where the alarm device includes a buzzer, the buzzer is installed on the battery fixing plate 1 corresponding to each battery position, and the infrared distance and temperature measuring module 20 includes an infrared temperature detector and an infrared distance meter.
The battery fixing plate 1 is used for fixing the monitored battery 10, the plurality of batteries 10 are arranged on the battery fixing plate 1 at intervals along one direction, the arrangement of the batteries 10 must be ensured to be orderly, and otherwise, the measurement accuracy of the infrared distance measurement and temperature measurement module 20 is affected. Two adjacent batteries 10 are connected in series, and the batteries 10 at two ends are respectively connected with an internal resistance monitoring system, so that the internal resistance change of the batteries 10 can be monitored.
The left end of the battery fixing plate 1 is provided with an adjusting device 2, the infrared distance measurement and temperature measurement module 20 is installed on the adjusting device 2, the infrared distance measurement and temperature measurement module 20 and the internal resistance monitoring system are respectively electrically connected with the background data processing control system, and the background data processing control system is electrically connected with the alarm device.
In the installation, infrared range finding temperature measurement module 20 is installed on adjusting device 2, and adjusting device 2 can carry out regulation about from top to bottom to infrared range finding temperature measurement module 20, and the infrared laser is not sheltered from before the assurance work, avoids causing the interference.
The working principle is as follows: firstly, the infrared distance measurement and temperature measurement module 20 is installed, and the adjustment device 2 is adjusted to ensure that the infrared laser emitted by the infrared distance measurement and temperature measurement module 20 is tightly attached to the surface of one side of the battery but is not blocked by the surface of the battery, and then the system is started to carry out real-time monitoring.
When the laser emission signal received by the infrared distance meter is the same as the initial value and the internal resistance monitoring system does not monitor the internal resistance change of the battery 10, the background data processing control system monitors the normal state and does not give an alarm; when a certain battery 10 deforms, an infrared laser reflection signal received by the infrared distance meter deviates from an initial value, and after the background data processing control system receives information fed back by the infrared distance meter and performs analysis processing, the alarm device is controlled to give an alarm. Because the distance from each battery 10 to the infrared distance measurement and temperature measurement module 20 on the battery fixing plate 1 is different, the background data processing and control system can calculate the position of a specific deformed battery according to a signal fed back by the infrared distance meter, meanwhile, the deformed battery buzzes corresponding to the buzzer, and a worker determines the replacement and maintenance of the battery 10 by synthesizing the feedback information of the infrared temperature detector and the internal resistance monitoring system, if all the feedback information of the infrared temperature detector and the internal resistance monitoring system is normal, the deformation of the battery 10 is not caused by the internal reasons of the battery, and if the feedback information of the infrared temperature detector and the internal resistance monitoring system indicates that the temperature of the deformed battery rises and the internal resistance becomes large, the internal part of the deformed battery is damaged and needs to be replaced.
