Current guiding device for live operation of distribution network with long-distance real-time monitor

Abstract

The invention relates to a mounting device for an overhead line or cable, in particular to a current guiding device for live operation of a distribution network with a long-distance real-time monitor, which is structurally characterized by comprising a pair of clamping devices, a high-voltage insulated connecting wire and a handheld monitor, wherein each clamping device comprises a movable jaw, a fixed jaw, a temperature sensor, a current sensor, a master control board and a current guiding connection device, each current guiding device is provided with the effective and reliable temperature sensor and current sensor for real-time collection of monitoring data, and the data are further wirelessly transmitted to the handheld monitor on the ground in a long-distance and real-time way within a controllable range for check of monitoring personnel, so that the monitoring personnel can promptly know the field construction situation, judgment can be made in a real-time way, correct prompts can be uttered in advance, the personal safety of operators can be guaranteed, the labor intensity can be lowered, the working pressure can be reduced, and the field construction safety of the live operation can be facilitated.

Description

technical field [0001] The invention relates to an installation device for overhead lines or cables, in particular to a drainage device for live work in a distribution network with remote real-time monitoring. Background technique [0002] In the existing technology, most projects of live work need to use line diversion technology, such as on-load breaking knife switch, on-load transfer line, on-load handling defects, etc., and there are two kinds of diversion technology solutions commonly used on-load and live electricity: one The first is a simple clamping device, which connects the two ends of the faulty line section and replaces the original wire for shunting, so that the faulty line can be cut off and the fault can be repaired. The line operation is safe and reliable, and it is suitable for single-point fault and short-distance line defect treatment. The other is the flexible cable system for bypass operation. The bypass operation system is a new type of distribution n...

Problems solved by technology

[0003] In the above technical solutions, no matter which one is used, it is necessary to operate the fixture or joint in close proximity, especially in the process of operation, before and after installing the drain wire, the operator needs to use a manual clamp ammeter to detect the fault of the circuit. The current data, before and after removing the lead wires, also need to be tested in the same way. In addition, when the staff moves and touches the installed lead wires, repeated detection should be carried out as needed. In this way, in a project, Multiple current detections are required, and the operation is very cumbersome for the operators. In the operation procedure, the operators are all close-up operations, and they must also visually observe the work of the drain wire that may be caused by poor contact, external voltage, and current abnormalities. Abnormal, in order to conduct on-site monitoring of the work of the drainage line

However, in order to ensure personal safety and connection reliability as much as possible, the part of the drain wire needs to be shielded with multiple insulations. Such shielding makes it difficult or even impossible for operators to perform visual inspection. In order to be able to monitor the work of the drain wire as much as possible, Operators need to be as close as possible to the installation point of the drainage line, which will cause safety hazards, lead to damage to tools or personnel to operate too close to cause personal safety accidents

[0004] In addition, the temperature parameters and current parameters in the working state of the drainage line are the main data for monitoring the operation of the drainage line. Under abnormal conditions, the above parameters will change greatly in an instant. Close-range detection of data is done regularly or according to needs, and cannot be detected in real tim
