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 time. Therefore, it is impossible to detect abnormalities in time, and it is impossible to remind operators to take safety precautions in time, and it is difficult to avoid potential safety hazards in line construction.

[0005] In addition, the on-site guardians are all monitoring remotely. According to the test data given by the operators, they can confirm with the guardians according to the operation steps and related matters before proceeding to the next step.

This means that the guardians cannot obtain the monitoring data and grasp the construction situation at the first time, so they cannot issue correct prompts in time, which increases the difficulty of guardianship

[0006] Therefore, the operator needs to keep a sufficient safety distance from the live body to ensure that the operation procedure is correct and the action is standardized during the operation, otherwise the personal safety of the operator and the reliable operation of the distribution network cannot be guaranteed, so higher requirements are put forward for the operator , which brings greater operating pressure to the operators, which is not conducive to safe production

On the other hand, because the clamps or joints in the prior art adopt an open clamping scheme, or simple clamping equipment, or remote manual operation (for example, an insulating operating rod is used to cooperate with a transmission mechanism with a screw), it causes its contact with the wire The reliability of the connection is often not guaranteed, and the manual operation often has uneven operating force and swaying operation direction. In addition, if some line contact is used instead of surface contact between the fixture or joint and the wire, it is easy to make the wire in the operation process. Or it will be damaged during repeated operations, which will increase the instability of distribution network operation
