Cooling device for photoelectric conversion module of online monitoring equipment for dissolved gas in insulating oil

Abstract

The invention relates to a cooling device of a photoelectric conversion module of online monitoring equipment for dissolved gas in insulating oil. The cooling device comprises a refrigerating system,a heat dissipation system and a temperature control system. The refrigerating system comprises a refrigeration module arranged on the outer surface of the photoelectric conversion module, and the refrigeration unit is a semiconductor refrigeration sheet. The heat dissipation system comprises at least one fan arranged on the outer side of the semiconductor chilling plate. The temperature control system is arranged close to the photoelectric conversion module and comprises a temperature sensor and a controller. The temperature sensor is connected to the input end of the controller, the semiconductor chilling plate and the fan are connected to the output end of the controller, and the preset temperature of the controller ranges from 20 DEG C to 40 DEG C. The semiconductor refrigeration systemis applied to the rapid and efficient heat dissipation requirement of the photoelectric conversion module for the first time, and reliable guarantee is provided for the safe and stable communicationmode of the online monitoring device for the dissolved gas in the oil.

Description

technical field [0001] The application relates to the technical field of on-line monitoring operation and maintenance of insulating oil, in particular to a cooling device for a photoelectric conversion module of an online monitoring device for dissolved gas in insulating oil. Background technique [0002] The on-line monitoring device for dissolved gas in oil mainly realizes on-line monitoring of the internal operating status of oil-filled electrical equipment such as large transformers and reactors by measuring and analyzing dissolved gas in insulating oil. It can detect and diagnose its internal faults in time, grasp the operating status of the equipment at any time, provide technical support for ensuring the safe and economical operation of oil-filled electrical equipment such as transformers, and is an important means to ensure the safe and economical operation of oil-filled electrical equipment and power grid systems. [0003] The communication method of the traditional...

AI Technical Summary

Problems solved by technology

After the communication mode was upgraded and operated, because only the communication part of the online monitoring device for dissolved gas in oil was upgraded, the heat dissipation capacity of the online monitoring device could no longer meet the fast and efficient heat dissipation requirements of the photoelectric conversion module in the IEC61850 communication mode. The photoelectric conversion module heats up seriously, which makes the communication operation unstable and leads to communication interruption, data loss and other problems

The final performance is that the online monitoring device has a high disconnection rate, and the online monitoring and protection function of the transformer and reactor is lost, which seriously affects the safe and stable operation of the equipment.
