Problems solved by technology

[0002] At present, there are the following problems in the power distribution of switching power supplies in communication offices: the DC load of the high-volume base station convergence point is basically greater than 100A, and two sets of 500AH batteries are configured according to the specifications. Five 50A rectifier modules are configured, and the active power will exceed 15KW; More than 200A, equipped with two sets of 1000AH batteries, equipped with 9 power modules according to the specifications, and the active power is nearly 30KW
This causes the following problems: (1) When the mains power fails, the 15KW mobile oil generator currently configured can only carry three 50A rectifier modules at most, and the maximum DC output is 150A, which cannot meet the requirements of the switching power supply to supply power to the load and The current demand for battery charging; (2) Larger capacity mobile generators need to be repurchased, which requires increased maintenance investment and increased operating costs, which is difficult to achieve under the current limited operating and maintenance costs; moreover, more Large-capacity mobile generators are larger in size and weight, and the current transportation tools cannot meet the requirements of mobile transportation; therefore, it is unrealistic to configure larger-capacity mobile generators; (3) The current switching power supply does not support multi-channel power generation machine power supply at the same time
[0003] Based on the above reasons, power generators generally use the rectifier module to limit the current or turn off part of the rectifier module for emergency power supply, resulting in a small charging current of the battery pack or continuous discharge, and the battery is insufficiently charged: the vulcanization of the battery plate is formed, which affects the life of the battery. Early scrapping requires more investment in replacement and update costs, resulting in a sharp increase in network operation and maintenance costs; at the same time, insufficient backup power supply capacity can easily lead to large-scale decommissioning of communication networks, which seriously affects operators' operating income and negatively impacts operators' business expansion social influence

Abstract

The invention relates to a power supply mode distribution system of a switch power supply generator set. The power supply mode distribution system comprises the generator set and a switch power supply rectifying module set, generators of the generator set correspond to switch power supply rectifying modules of the switch power supply rectifying module set one by one and are connected with them via generator input switches, connection switches are arranged between the switch power supply rectifying modules of the switch power supply rectifying module set, the connection switches are linked with a mains supply power switch to form a mains supply power switch group, the generator input switches are mutually linked to form a generator power supply switch group, the mains supply power switch group is mechanically interlocked with the generator power supply switch group, and each generator supplies power for the corresponding switch power supply rectifying module. By mechanical interlocking, mains supply and power generation are safely isolated; two generators supply power for two bus bars of the switch power supply rectifying module. The problem of parallel operation and synchronism is avoided, and equipment modification cost is very low.
