Description

Technical Field

[0001] The present invention relates to the technical field of line protection, and in particular to a distribution network line protection device. Background Art

[0002] In places where thunderstorms are frequent, communication lines are often damaged by lightning strikes, mainly because some components of the communication system are exposed outdoors and are easily damaged by lightning strikes. When the power grid has non-grounding faults such as line break, non-full phase, capacitive coupling of the same pole line, etc., the asymmetric voltage of the power grid increases, which may cause the automatic adjustment controller of the arc suppression coil to misjudge that the power grid has grounded. At this time, a very high neutral point displacement voltage will be generated in the power grid, causing one or two phases of the system to increase the voltage a lot, so that other equipment in the power grid is damaged.

[0003] Usually a grounding wire is used to reduce the danger. However, if the wires are connected to the ground directly on the utility pole, the wires will be suspended in the air.

The fastener 102 is arranged on the container 101. The initial installation of the device can be achieved through the mutual cooperation of the container 101 and the fastener 102.

[0043] Specifically, the accommodating member 101 includes an electric pole 101a, a rectangular rod 101b is fixedly installed on the top side of the electric pole 101a, a plurality of insulators 101c are fixedly installed on the top of the rectangular rod 101b, a plurality of first fixing rings 101d are sleeved on the electric pole 101a, a second fixing ring 101e is hingedly installed on one side of the first fixing ring 101d, a first rubber gasket 101f is fixedly installed on the opposite side of the first fixing ring 101d and the second fixing ring 101e, and the first fixing ring 101d and the second fixing ring 101e are connected to each other to fit on the electric pole 101a, and the first rubber gasket 101f can be used to achieve insulation and increase the safety of operation.

[0044] Further, the fastener 102 includes a first rectangular groove 102a, the first rectangular groove 102a is arranged on the first fixing ring 101d, the second fixing ring 101e is provided with a second rectangular groove 102b, a threaded rod 102c is rotatably installed in the first rectangular groove 102a, one side of the threaded rod 102c passes through the second rectangular groove 102b, a nut 102d is threadedly installed on one side of the threaded rod 102c and located on one side of the second rectangular groove 102b, and the nut 102d is fixedly installed with a second rubber gasket 102e on the side of the nut 102d that is biased toward the second rectangular groove 102b.
