Description

TECHNICAL FIELD

[0001] The utility model belongs to communication technical field relates to a quick access's continuation flow communication power module. BACKGROUND

[0002] DC24V / 80A direct current power module as the key component of railway signal power supply screen, plays the role of providing stable DC24V power supply for important facilities such as relay, ZPW-2000A station internal coding system and interval frequency shift track equipment. These power modules are usually designed into "N+1" or "N+M" parallel current-sharing redundant standby working mode, wherein "N" represents the minimum module quantity actually required, and "+1" or "+M" represents the additional backup module, to ensure that the system can seamlessly switch to the standby module when the main module fails, so as to maintain the continuity and stability of power supply. According to the scale, layout of railway station and the specific needs of signal equipment, the configuration number of power module and the number of output beams will be different to meet the complex and variable needs of railway signal control.

[0003] However, in actual application, these power modules often need to run in outdoor harsh environment for a long time, facing high temperature, humidity, dust and extreme weather and other unfavorable factors. This long-term exposure to harsh environment undoubtedly increases the risk of power module failure. Once the power module fails or the power supply line is accidentally cut off, it will directly cause the railway signal lamp to lose power supply, and then the signal lamp cannot work normally or display the correct signal state. This situation not only brings great safety hazards to train operation, but also may cause the railway traffic system to be in chaos, seriously affecting the normal operation of the railway and the travel experience of passengers. More seriously, since the existing power monitoring and fault warning system may not be perfect, when the power module fails, it often cannot send out an alarm in time and take corresponding emergency measures. This further aggravates the impact of the failure on the railway operation, making the fault diagnosis and repair work more difficult and time-consuming. Therefore, how to improve the reliability and stability of the power module, and perfect the fault warning and emergency response mechanism, has become an important problem to be solved in the current railway signal power system.
