Embodiment Construction
[0027] The embodiment of the present invention provides a DC charger ripple monitoring device, which is used to solve the aging of the traditional DC charger. The output ripple coefficient exceeds the specified limit, and the staff cannot find out in time, which leads to the excessive ripple coefficient of the charger. The technical problems caused by the deterioration of battery performance and shortened service life.
[0028] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinar...

The invention provides a direct current charger ripple monitoring device. The direct current charger ripple monitoring device comprises a direct current charger, a direct current ripple sensor, and an alarming module. The direct current ripple sensor is connected with the output end of the direct current charger, and the alarming module is connected with the direct current ripple sensor. The direct current charger ripple monitoring device is advantageous in that the output end of the direct current charger is provided with the direct current ripple sensor, and the ripple coefficient of the output end is measured in a real-time manner; when the ripple coefficient exceeds a limit value required by a regulation, a signal is sent to prompt a worker to carry out inspection processing; and the inspection can be carried out without waiting for the regular inspection of the direct current system, and therefore performance degradation and shortening of service lifetime of a storage battery caused by the overlarge ripple coefficient of the charger are prevented.
Description
Technical field [0001] The invention relates to the technical field of DC charger ripple monitoring, in particular to a DC charger ripple monitoring device. Background technique [0002] At present, the power system promotes unattended substations. Although the dispatch center can obtain real-time information on the operation of the substation through the remote control channel, only a small amount of important information can be obtained for the DC part. For the charger, its performance indicators such as ripple coefficient, voltage stabilization accuracy, current stabilization accuracy and current sharing characteristics, etc., due to the lack of corresponding online test equipment, it is difficult to confirm whether the requirements are met, and the problems cannot be found in time. The consequence is premature failure or damage of the battery, which directly threatens the safe operation of the power grid. In the early days, the technical indicators reached by the charger wer...
