Abstract

The invention relates to a PMU device for a power distribution network. The PMU device includes a casing and an electronic circuit board built in the casing. A cavity is arranged in the casing. The casing includes an upper casing and a lower casing that can be separated from each other. The cavity comprises a first cavity and the second cavity that are arranged opposite to each other in the uppercasing and the lower casing in a separate manner. The first cavity and the second cavity are respectively provided with an upper semi-cylinder groove and a lower semi-cylinder groove. The first cavityand the second cavity are further provided with current transformers; the PMU device further includes an open-close locking mechanism. By twisting an open-close screw rod, the device disclosed in theinvention can be rapidly opened and closed in stalling and dismounting processes; by operating a special purpose insulating operation rod, the PMU device can be quickly installed on a 380V-35kV powerline in an electrified and equipotential manner.

Description

technical field [0001] The invention relates to a distribution network PMU device. Background technique [0002] The existing medium and low voltage power distribution overhead lines (380V-35kV) are fault-prone lines, and a large number of sensing devices are required to monitor the lines and locate faults. Due to issues such as power grid operation costs and grid operation safety, it is necessary for the sensing device to be installed safely, conveniently and quickly at the measurement position required by the power line, and to ensure that locking the power line will not cause accidents such as rotation, sideslip, or even falling of the device itself. . In the vast majority of installation situations, it is required that the sensing device can be installed or disassembled without power failure of the power grid, which requires the sensing device to be able to safely and quickly realize the opening and hooking of the power line from the device by using an insulated operati...
