Abstract
The invention provides a composite insulator live-line detector of a power transmission line. The composite insulator live-line detector comprises a probe (1), an insulating rack (2) provided with the probe (1) and a connecting handle (3) for fixing the insulating rack (2), wherein the probe (1) is an electric field detection probe, and comprises a communication interface and a liquid crystal display panel which are connected in series, the probe (1) is in a flat structure, and the insulating rack (2) is in a trapezoid-structure. Compared with the prior art, the composite insulator live-line detector of the power transmission line has the beneficial effects of small volume, convenience in detection, accuracy in judgment, wide application range and low cost.
Description
Technical field
The present invention relates to electronic applications, relate in particular to a kind of pick-up unit, specifically the charged detector of a kind of transmission line composite insulator.
Background technology
Detect the domestic method that mostly adopts at present range estimation for composite insulator, but when having had obvious defective, the composite insulator outside surface that the method for this range estimation only has just can observe, but be difficult for being found for the defective of composite insulator inside owing to reason generations such as wearing out, and insulation mandrel is the core component of composite insulator, insulating effect in rising, be used for guaranteeing machinery, the electrical specification of composite insulator, if insulation mandrel goes wrong, then may cause wire to land, thereby produce great potential safety hazard.
Therefore, how when going wrong in inside, composite insulator can be detected as timely and effectively the technical matters of being badly in need of solution for one.
Summary of the invention
The technical problem to be solved in the present invention is for the existing deficiency of prior art, provides that a kind of volume is little, easy to detect, accuracy of judgement, the charged detector of transmission line composite insulator applied widely and lower-cost.
Technical scheme of the present invention is, the charged detector of a kind of transmission line composite insulator, comprise probe, the insulator support that probe is installed and the connection handle of fixed insulation carriage, described probe is the electric field detection probe and comprises serial communication interface and display panels.
As preferably, described probe is the flat structure.
As preferably, described insulator support is trapezium structure.
As preferably, described connection handle is the metal connecting link.
As preferably, also be provided with the angle adjustable mechanism between described connection handle and the insulator support.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because the present invention has adopted the electric field detection probe of autonomous Design making as main detection module, utilize the characteristic that the electric field of composite insulator rejected region can distorted to come composite insulator is detected, compare by the Electric Field Characteristics curve to normal composite insulator and can obtain that position of composite insulator and problem occurred.In addition, the present invention adopts the sonde-type structure and adopts carriage to be connected with connection handle, structure is very simple, reduced volume, in addition, reflection type photoelectricity triggering technique, diode level conversion technology, half-wave integration technology, voltage-frequency switch technology, average noise-removed technology and whole hardware filtering technology have also comprehensively been adopted in probe inside, thereby so that the formation of metering circuit is exquisite compact, sliding speed is on the impact of measurement result when having reduced probe and sliding, thereby so that the stability that detects greatly improve; Also have probe to adopt the flat structure, longitudinal size is little, the area of electrode is large, reduced the change of probe to former longitudinal electric field, thereby improved the degree of accuracy of measurement and the sensitivity that defects of insulator detects, realized digital proof, the charged detector of transmission line composite insulator of the present invention can detect the long defective of insulator high-pressure side 7cm, the defective of middle part 15cm can also detect the long defective of high-pressure side 5cm under the individual cases; Moreover, but the angle adjusting mechanism detector that insulator support of the present invention and connection handle are provided with is applicable to the various shaft towers that diameter is 100mm～200mm, the composite insulator of various setting angles; The present invention also is provided with serial communication interface and is convenient to reading of data.
