The utility model discloses a kind of Novel high-voltage cable terminal and joint on-line monitoring device, including stress cone, measure sensor and transmission signal optical cable, the core wherein measuring sensor and transmission signal optical cable is embedded in inside stress cone, measures sensor and is connected with Signal Terminal by transmission signal optical cable.Sensor is embedded in advance the inside of stress cone when factory manufactures stress cone, and stress cone uses silicone rubber or uses EPDM bullet to manufacture.This Novel high-voltage cable terminal and joint on-line monitoring device can measure the heat at stress cone position, the change of noise at minimum distance, have the sensitivity of excellence, accuracy, reliability, anti-interference relative to other measurement means.And this cable on-line monitoring device solves cannot the difficult problem of accurate on-line monitoring.
Description
Technical field
This utility model relates to power cable field, specifically a kind of Novel high-voltage cable terminal and joint on-line monitoring device.
Background technology
Existing on-line monitoring of cable uses distributed smooth pricker measuring method, this method be cable outer jacket colligation temperature-sensitive light unit signal acquisition and be transferred to a distant place measure, on-line measurement noise (shelf depreciation) is to meet the operational monitoring requirement of major part cable at it, but being placed in outside protective coverings of cable owing to measuring sensor, measured value is the most inaccurate obviously can not meet on-line monitoring requirement；On-line measurement noise (shelf depreciation) is to install on cable splice case and near the tail pipe of cable termination to measure sensor, and due to distance point of discharge (typically near stress cone and shielded-plate tube) 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 be to provide a kind of close-in measurement and have good measurement effect measure heat, noise change on-line measurement device can reflect the operating situation of cable exactly.
This utility model includes stress cone, measures sensor and transmission signal optical cable, and the core wherein measuring sensor and transmission signal optical cable is embedded in inside stress cone, measures sensor and is connected with Signal Terminal by transmission signal optical cable.
Improving further, the described core measuring sensor and transmission signal optical cable is embedded in inside stress cone in advance
Improving further, described stress cone 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 stress cone position, the change of noise at minimum distance, has the sensitivity of excellence, accuracy, reliability, anti-interference relative to other measurement means.And this cable on-line monitoring device solves 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 shown in Figure 1, including stress cone (1), measure sensor (2) and transmission signal optical cable (3), the core wherein measuring sensor (2) and transmission signal optical cable (3) is embedded in inside stress cone, measures sensor (2) and is connected with Signal Terminal by transmission signal optical cable (3).
Measurement sensor is embedded in advance the inside of stress cone when factory manufactures stress cone, and stress cone 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.
