Abstract

The invention relates to the technical field of electrical power systems, in particular to a current data collecting device for an electric transmission line to achieve the technical purpose of monitoring the electric transmission line. The current data collecting device comprises an insulator, a protection cover, a caliper type current transformer and two waterproof blocks. The insulator is an insulating cylindrical bottle. The caliper type current transformer is inserted in a bottle cavity of the insulator in a movable fit mode. A caliper mouth and an operating handle of the caliper type current transformer upwards extend out of the bottle opening of the insulator. The protection cover is detachably installed in the bottle opening of the insulator and covers the caliper type current transformer, and the protection cover is provided with a left wiring opening and a right wiring opening communicated with each other. The two waterproof blocks are arranged on the left side and the right side of a cable base respectively and cover the two wiring openings of the protection cover respectively. The centers of the waterproof blocks are provided with wiring holes for a cable to pass through, and the wiring holes are communicated with each other left and right. The current data collecting device is suitable for collecting current data of the electric transmission line, and capable of being used in the open air for a long time.

Description

technical field [0001] The invention relates to power system technology, in particular to a technology of a transmission line current data acquisition device. Background technique [0002] In the power system, when the transmission line fails, it is necessary to find out the fault point and repair the fault line in time to restore the normal power supply. Since the transmission lines are exposed to the outdoor environment and have been exposed to the sun and rain for a long time, the relevant monitoring devices for monitoring the working conditions of the transmission lines need to have strong waterproof performance, and the existing current and voltage acquisition devices are not suitable for long-term use in the field . [0003] The existing transmission line fault monitoring method is: set a monitoring node every certain distance on the transmission line, and install a fault indicating device on each monitoring node, an indicator is arranged on the fault indicating devic...
