Embodiment Construction
[0031] Now take the 220V DC system 2×1500AH lead-free battery complete set of DC panel as an example, and then describe the specific implementation and working principle in conjunction with accompanying drawings 1, 2, and 3. It is known that the constant load such as control signals is 65A, the accident load is 660A, the float charge voltage of each battery is 2.23V, the float charge current of each battery group is 1.5A at the initial stage, and the maximum at the later stage is 6A, and the DC bus voltage is 230V.
[0032] In Fig. 1, two DC busbars 1M and 2M are connected to control signal load 1N, closing load 2N, emergency lighting 3N, DC oil pump 4N and all normal and emergency DC loads. The anti-circulation channel is composed of 1D-4D4 diodes.
[0033] The pulsating DC 26.4V between the 5 and 6 terminals of the floating charger 1CDJ, the 6 and 7 terminals are connected, and the 229.7V pure DC voltage output between the 7 and 8 terminals is directly supplied to 1M and 2M ...
