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 ring main unit partial discharge and temperature real-time online monitoring system. The system comprises a case. An on-line monitoring system circuit board, a wireless signal transmitting module and a rotary positioning device are installed inside the case. A cyclic temperature detection device is installed on the rotary positioning device. The rotary positioning device includes a rotary motor. According to the invention, the rotary positioning device and the cyclic temperature detection device are combined, the rotary positioning device can enable the cyclic temperature detection device to rotate a specific angle, and the cyclic temperature detection device can drive a first temperature sensor to adjust the distance from the rotary positioning device. By combining the rotary positioning device and the cyclic temperature detection device, the first temperature sensor can reach any position of the on-line monitoring system circuit board through a simple structure, and a specific area of the on-line monitoring system circuit board can be detected according to the actual need of the on-line monitoring system circuit board. Thus, 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...
