Description
The application is application number：201310210844.4, the applying date：2013.5.31, title " loop resistance test lightweight
The divisional application of compound inslation bar ".
Technical field
The present invention relates to a kind of loop resistance to test lightweight compound inslation bar.
Background technology
High-potting is the important component of electrical test, and ensures the crucial portion that power system security is effectively run
Point.During high-potting, the safety for ensureing testing crew and equipment is top priority, particularly personal safety.Pass
Loop resistance test insulating bar of uniting uses the fit system of outside overlap joint with p-wire.In which, due to insulating bar and experiment
Line is heavier, p-wire tilts naturally etc. larger horizontal pull is produced to insulating bar, in addition, wind-force traction is to the steady of insulating bar
It is qualitative also to have considerable influence.The design of conventional circuit resistance test insulating bar and technologic imperfection cause during high-potting
Potential safety hazard be present, it is in recent years to have the personal flash burn accident for occurring thus to trigger more.In addition, in power system production scene
During actual use, the situation of the thicker oxide layer that needs to rub of altitude plant surface oxide layer often occurs, it is existing to use
Jointing clamp contact surface is smoother, friction is too small, in-convenience in use.At actual production scene, operating personnel also feel operation not side
Just, it is therefore necessary to which conventional circuit resistance test insulating bar is improved.
The content of the invention
It is an object of the invention to provide a kind of rational in infrastructure, good, the safe to use loop of the operational stability of insulating bar
Resistance test lightweight compound inslation bar.
The present invention technical solution be：
A kind of loop resistance tests lightweight compound inslation bar, it is characterized in that：Include the first segment containing jointing clamp, more piece successively
Middle node insulating bar, most minor details insulation bar and pigtail connection；Transit joint is set between first segment and middle node insulating bar；Survey
Electric current line on probation is directly cast in inside glass epoxy resin compound inslation bar, forms water conservancy diversion copper conductor, is often saved in insulating bar
Connected between water conservancy diversion copper conductor by the copper nipple at its both ends；Test pressure-wire passes through among insulating bar, electric current
Line is drawn and circuit resistance tester device at the top of head section insulating bars with wiring clipper joint, electric current line, pressure-wire from pigtail connection
Connection, and pressure-wire is pressed into from the side wire casing on pigtail connection.
Electric current line is connected by the transit joint provided with binding post with the terminals of jointing clamp, and transit joint is provided with electricity
Line ball passes through hole.
Minor details insulating bar bottom is provided with protective jacket.
The present invention it is rational in infrastructure, reduce insulating bar be put to the test line tractive force and wind-force effect influence.Test electricity consumption streamline
Directly it is cast in inside insulating bar, forms baffle；Test pressure-wire passes through among insulating bar, turns into same with insulating bar
To reducing p-wire to the influence of horizontal pull caused by insulating bar and wind-force to insulating bar stability；Alleviate insulation
The gross weight of bar and test wire.Because water conservancy diversion copper conductor is cast in inside insulating bar, water conservancy diversion copper conductor surface does not wrap up insulating barrier,
Insulating bar outer wall realizes External Insulation；P-wire is vertical, does not tilt, and experiment line length needed for test is reduced, so as to mitigate
The gross weight of insulating bar and test wire.
By the way that test wire is cast on insulating bar inwall, reduce the tractive force of test wire and wind-force to insulating bar, one
Determine to reduce the overall weight of insulating bar and test wire during experiment in degree, to improve the stability of insulating bar, ensure and use
The personal safety of person, meet high-voltage test on-site practical application request.
