Abstract

The invention discloses a novel on-line monitoring device for a high-voltage cable connector. The novel on-line monitoring device comprises a connector box, a screening tube is installed inside the connector box, and a passive wireless measurement sensor is embedded into the screening tube; the external portion of the connector box is connected with a transmission signal optical cable through a wireless receiver. The novel on-line monitoring device for the high-voltage cable connector can measure the heat and noise changes of a stress cone portion within the closest distance and transmit the changes to the wireless receiver on a shell of the connector through wireless signals and then transmits the changes to a measurement instrument through an optical cable. Compared with other measurement means, the novel on-line monitoring device has excellent sensitivity, accuracy, reliability and anti-interference, and the on-line monitoring device for the cable solves the problem that on-line monitoring can not be performed accurately.

Description

A kind of Novel high-voltage cable joint on-line monitoring device
Technical field
The present invention 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) detecting unit on cable splice case, the Signal transmissions captured is measured to a distant place, although it can meet the operational monitoring requirement of a part of cable splice, but because survey sensor is placed in outside cable jacket, measured value is often extremely inaccurate obviously can not meet on-line monitoring requirement; And on-line measurement noise (shelf depreciation), because distance point of discharge is comparatively far away, on-the-spot high frequency interference is comparatively large, is difficult to obtain promising result.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of close-in measurement and has the Novel high-voltage cable joint on-line measurement device of the measurement heat of good measurement effect, noise change, can reflect the operating situation of cable splice exactly.
The present invention includes connector box, shielded-plate tube is equipped with in connector box inside, and shielded-plate tube inside is inlaid with passive and wireless survey sensor; Connector box outside is connected with signal transmission optical cable by wireless receiver.
Further improvement, is embedded in shielded-plate tube inside when passive and wireless survey sensor manufactures in advance.
Further improvement, described shielded-plate tube adopts silicon rubber or ethylene propylene diene monomer (EPDM) material.
Beneficial effect of the present invention:
The present invention can measure the heat at shielded-plate tube position, the change of noise at minimum distance, relative to other measurement means, there is excellent susceptibility, accuracy, reliability, anti-interference, and this cable splice on-line monitoring device solves in cable splice and cannot install and measure device, and cannot the difficult problem of accurate on-line monitoring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Structure of the present invention as shown in Figure 1, comprises connector box, and shielded-plate tube 1 is equipped with in connector box inside, and shielded-plate tube 1 inside is inlaid with passive and wireless survey sensor 2; Connector box outside is connected with signal transmission optical cable 4 by wireless receiver 3.
When factory manufactures shielded-plate tube, sensor is embedded in advance the inside of shielded-plate tube, shielded-plate tube adopts silicon rubber or adopts the manufacture of Ethylene Propylene Terpolymer bullet.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
