Embodiment Construction
[0032] Please check figure 1 , figure 2 and image 3 , a GPRS-based moisture-proof temperature control system for ring main units, including a monitoring terminal 1, a data concentrator 2 and a monitoring center 3. The ring network cabinet is equipped with tide-removing equipment, which includes a heating unit, an exhaust fan and a semiconductor refrigeration device. According to needs, only a heating unit can also be provided.
[0033] The monitoring terminal 1 is installed in the ring network cabinet, and includes a first controller 11, a first power supply 12, a temperature and humidity sensor 13, a relay drive circuit 15, a first ZigBeeRF module 18, a digital tube display module 16 and a limit sensor 14. The first controller 11 is connected to the temperature and humidity sensor 13 , the relay drive circuit 15 , the first ZigBeeRF module 18 , the nixie tube display module 16 and the limit sensor 14 . Among the present embodiment, this first controller adopts the PIC24...

The invention discloses a ring main unit damp-proof temperature control system and method based on the GPRS. The ring main unit damp-proof temperature control system comprises a monitoring terminal, the monitoring terminal is installed on a ring main unit, can at least obtain temperature and humidity information and can generate driving instructions according to the temperature and humidity information and preset valve conditions, and the driving instructions can control a damp removing device of the ring main unit. The ring main unit damp-proof temperature control system further comprises a data concentrator and a monitoring center, the data concentrator can be in wireless communication connection with the monitoring terminal, the data concentrator and the monitoring center can be in communication connection through the GPRS so that the data concentrator can periodically obtain the temperature and humidity information of the ring main unit, send obtained data to the monitoring center according to instructions of the monitoring center and transfer the instructions sent by the monitoring center to the monitoring terminal, and the monitoring terminal carries out the instructions. A wireless communication technology and GPRS communication means are adopted to monitor the running environment of the outdoor ring main unit in real time, no person needs to be specially assigned for regular inspection of the ring main unit, the workload is reduced, the automation level is improved, potential safety hazards are reduced, and a device can run safely and stably.
Description
technical field [0001] The invention relates to the field of electric power distribution network, in particular to an on-line monitoring and remote control system and method for moisture-proof and temperature control of ring network cabinets based on GPRS. Background technique [0002] The distribution network ring main unit is an important equipment of the power system, which ensures the reliability of the power supply of the power system. In southern China, the rainy season is longer, with more rainfall and higher humidity. In addition, the bottom of the ring network cabinet is not sealed tightly. When the temperature difference between day and night is large, the humidity in the cabinet is relatively high, and there are terminal row corrosion and water droplets. form. Once the ring network cabinet is seriously damp, it will cause the insulation resistance of the AC and DC circuits to the ground to decrease, or be grounded or short-circuited, causing false alarms, malfunc...
