Housing structure of DPMU distribution network synchronous phasor measuring device

Abstract

The invention discloses a housing structure of a DPMU distribution network synchronous phasor measuring device. The housing structure comprises an upper housing assembly, a lower housing assembly, anda measuring housing assembly. The upper housing assembly includes a first latch, a second latch, two bolt rings, an upper housing waterproof sheet, an upper housing rubber gasket, and an upper housing adhesive piece. The lower housing assembly includes a lower housing, a lower housing adhesive piece, and a lower housing rubber gasket. The measuring housing assembly is connected with the lower housing assembly by a bolt. One end, fitting the lower housing assembly, of the upper housing assembly is fixed by the first latch to form a movably opening-closing integrated part; and the other end ofthe upper housing assembly passes through latch rings of two bolt rings by the second latch. After the bolt rings rotate downwardly at an angle of 180 degrees, screwing rings of the bolt rings block the edge of the lower housing; the screwing rings are rotated clockwise and thus semi-circular wire slots of the upper housing and the lower housing form a concentric circle; the rubber gaskets are closed up and down to clamp the wire and the wire is separated from the housing. The housing structure is suitable for installation of wires with various diameter specifications at a 10-kV overhead line.

Description

technical field [0001] The invention relates to a 10kV overhead line power grid fault monitoring system, in particular to a shell structure of a DPMU distribution network synchronized phasor measuring device. Background technique [0002] In view of the fact that our company has developed a DPMU distribution network synchrophasor measurement device, in order to reduce production costs, improve production efficiency, and improve installation and maintenance efficiency, we have developed a shell structure for the DPMU distribution network synchrophasor measurement device. [0003] At present, the distribution network fault detection device generally adopts an all-plastic shell, and uses spring clips and spring pressing pieces to compress the wires inside. The plastic casing has been exposed to high-intensity ultraviolet rays outdoors and corroded by rain for a long time. After two to three years, the casing will crack or even break, causing the device to fall. [0004] The fa...

The plastic casing has been exposed to high-intensity ultraviolet rays outdoors and corroded by rain for a long time. After two to three years, the casing will crack or even break, causing the device to fall

[0004] The fault detection device uses spring clips and spring sheets to clamp the wires. Relying on the spring clips and spring sheets alone is easy to cause loosening, and the equipment will move under the force of the wind. The spring clips and spring sheets are always stressed. Fatigue effect will be produced under the pressure, which will reduce the clamping force and cause the device and wire to loosen
