Problems solved by technology
In order to prevent dust from entering the existing ring network cabinet, the upper part of the ring network cabinet is mostly designed as a closed structure. As the hot air rises, the upper part of the ring network cabinet will accumulate heat, which reduces the heat dissipation of the ring network cabinet

The invention discloses a real-time on-line monitoring system for partial discharge and temperature of a ring network cabinet, which includes a chassis, an on-line monitoring system circuit board, a wireless signal transmitting module, and a rotary positioning device are installed inside the chassis, and a circulating temperature detection device is installed on the rotary positioning device. The rotary positioning device includes a rotary motor. The rotary positioning device of the present invention is combined with the circulation temperature detection device. The rotation positioning device can rotate the circulation temperature detection device at a specific angle, and the circulation temperature detection device can drive the first temperature sensor to adjust and rotate the positioning device. The distance, the combination of the rotation positioning device and the cycle temperature detection device can make the first temperature sensor reach any position of the circuit board of the online monitoring system through a simple structure, and the specific area of the circuit board of the online monitoring system can be adjusted according to the actual needs of the circuit board of the online monitoring system detection, so that the temperature detection value is more accurate.
Description
technical field [0001] The invention relates to an on-line detection device, more precisely a real-time on-line monitoring system for partial discharge and temperature of a ring network cabinet. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has a structure Simple, small size, low price, can improve power supply parameters and performance, and power supply security and other advantages. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. In order to prevent dust from entering the existing ring main unit, the upper part of the ring main unit is mostly designed as a closed struc...
