Abstract
The invention discloses a novel high voltage cable terminal and joint on-line monitoring device. The novel high voltage cable terminal and joint on-line monitoring device includes a stress cone, a measurement sensor, and a transmission signal optical cable, wherein the measurement sensor and a core of the transmission signal optical cable is inlayed in the stress cone; and the measurement sensor is connected to the signal terminal through transmission signal optical cable. The sensor is inlayed in the stress cone in advance when the stress cone is produced in a factory. The stress cone is made of a silicone rubber or ethylene propylene diene monomer elastic rubber. The novel high voltage cable terminal and joint on-line monitoring device can measure the change of the heat and the noise at the stress cone position in the closest distance, and has excellent sensitivity, accuracy, reliability and anti-interference performance relative to other measure means. The cable on-line monitoring device solves the problem that the accurate on-line monitoring can not be performed.
Description
Technical field
The present invention 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 often extremely 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 (being 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。
Summary of the invention
The technical problem to be solved 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。
