Abstract
The utility model discloses a novel high tension cable connects on -line monitoring device, including the splice box, the inside shielded -plate tube that is equipped with of splice box, inside the inlaying of shielded -plate tube has passive antenna measuring transducer, the splice box is outside to be connected with the transmission signal optical cable through wireless receiver. This kind of novel high tension cable connects on -line monitoring device can be in the heat at nearest distance measurement stress cone position, the change of noise, through the radio signal transmission to connecting the wireless receiver on the shell, the rethread optical cable conveys measuring instrument. Have excellent sensitiveness, accuracy, reliability, interference immunity for other measuring means. And this kind of cable on - line monitoring device has solved unable accurate on -line monitoring's a difficult problem.
Description
Technical field
This utility model relates to power cable field, specifically a kind of Novel high-voltage cable joint on-line monitoring device.
Background technology
Existing high-voltage cable joint on-line monitoring uses distributed smooth pricker measuring method, this method is colligation temperature-sensitive light unit, noise (shelf depreciation) detector unit on cable splice case, the signal captured is transferred to a distant place measure, although it can meet the operational monitoring requirement of a part of cable connector, but being placed in outside cable jacket owing to measuring sensor, measured value is the most inaccurate obviously can not meet on-line monitoring requirement；And on-line measurement noise (shelf depreciation), due to distance point of discharge farther out, on-the-spot High-frequency Interference is relatively big, is difficult to obtain promising result.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of close-in measurement and has the measurement heat of good measurement effect, the Novel high-voltage cable joint on-line measurement device of noise change, can reflect the operating situation of cable connector exactly.
This utility model includes connector box, equipped with shielded-plate tube inside connector box, is inlaid with passive and wireless and measures sensor inside shielded-plate tube；Connector box is outside to be connected with transmission signal optical cable by wireless receiver.
Improving further, passive and wireless is measured when sensor manufactures and is embedded in advance inside shielded-plate tube.
Improving further, described shielded-plate tube uses silicone rubber or ethylene propylene diene monomer (EPDM) material.
The beneficial effects of the utility model:
This utility model can measure the heat at shielded-plate tube position, the change of noise at minimum distance, relative to other measurement means, there is the sensitivity of excellence, accuracy, reliability, anti-interference, and this cable connector on-line monitoring device solves cannot install measurement apparatus in cable connector, and cannot the difficult problem of accurate on-line monitoring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
This utility model structure is as it is shown in figure 1, include connector box, and equipped with shielded-plate tube 1 inside connector box, the internal passive and wireless that is inlaid with of shielded-plate tube 1 measures sensor 2；Connector box is outside to be connected with transmission signal optical cable 4 by wireless receiver 3.
Sensor is embedded in advance the inside of shielded-plate tube when factory manufactures shielded-plate tube, and shielded-plate tube uses silicone rubber or uses EPDM bullet to manufacture.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement, these improvement also should be regarded as protection domain of the present utility model.
