Description
Technical field
The present invention relates to electric line on-line monitoring equipment more particularly to a kind of fault detectors.
Background technique
As the Main physical equipment of grid power transmission link, transmission line of electricity is the most huge component part of electric system,
Running environment is severe, with a varied topography, maintenance is difficult, there is important influence to the safety and reliability of electric system.Therefore, exist
In looped network distribution system, in especially a large amount of systems using ring net load switch, if sent out in next stage distribution network system
Short trouble or ground fault are given birth to, the power supply system of upper level must carry out disjunction before the deadline, to prevent
Major accident.
Fault detector be for detect and recognize power circuit whether the equipment of failure, its working principle is that working as power line
When the failures such as short circuit, ground connection occurs in road, since electric parameter is mutated in route, magnetic field and electric field are generated around power circuit
Change, the control route inside electric power line fault indicator detects automatically and judge malfunction, determines fault section, branch
And fault point, and then alarm signal driving display portion work is exported, and alarm indication is red, to reach instruction fault wire
The purpose on road, in order to line walking, staff performs overhauling and maintenance route.
Existing fault detector is suspended on outdoor aerial high-voltage conducting wire by wire clipping component, and wire clipping component is basic
The crimping spring being hingedly mounted in lower case by two forms, and crimping spring is arranged in lower case two sides and to lower case upper end
Center rotatably compresses conducting wire, and electric field induction signal is exported by crimping spring, articulated shaft and electric field lead-out wire from electrical connector, from
And complete the sampling of fault detector.By long-term using practice, it has been found that the clamp group of above-mentioned existing fault detector
Part has the disadvantage in that
One, crimping spring is the pinching action realized using flexible deformation, and after long-term use, flexible deformation can be by
The failure of step causes the clamping force of crimping spring smaller and smaller, and pressure spring cannot compress conducting wire, gently move then body,
It rocks, it is heavy then body is made directly to fall breakage from high-voltage conducting wires, in some instances it may even be possible to falling object from high altitude occur and pound the safe thing that people damages object
Therefore.
Two, to prevent housing conductive from leaking electricity, cause people safe, the shell of fault detector is all by nonconducting plastics material
Matter is made, and is directly born against high-voltage conducting wires on shell using the deformation force of crimping spring, whether in the hinge with crimping spring
Place is met, also at the stress of high-voltage conducting wires, the stress cracking problem occurred because local pressure is too quickly can all occur sooner or later in shell,
The sealing performance of shell is caused to fail, product water inlet influences service life.
In consideration of it, overcoming the above defect in the prior art, it is urgently to be resolved as this field to provide new fault detector
The technical issues of.
Summary of the invention
The purpose of the present invention is to solve the shortcomings of the prior art place, provide a kind of upper shell component and lower shell component not by
Chucking power, fastening assembly clamp strong and long-acting fault detector.
This fault detector provided by the invention, including upper shell component, lower shell component, fastening assembly and take can set of samples
Part, upper shell component are articulated on lower shell component, and fastening assembly includes upper fastening block, lower fastening block, screw rod and u-bracket, U-shaped branch
Frame is mounted in lower shell component, and screw flight is connected in u-bracket, and screw rod bottom gap is through lower shell component, top under
Fastening block is rotatably connected, and upper fastening block is articulated in u-bracket and is fixed in upper shell component, and sense is equipped on upper fastening block
Warm probe hole and electric field screw hole, upper shell component drive upper fastening block to overturn in u-bracket in the overturning of lower shell component, upper fastening block
With u-bracket by snap lock, upper shell component and lower shell component by snap lock, screw rod rotation drives lower fastening block in U
It is moved up and down in type bracket, lower fastening block, which is moved up, clamps conducting wire with upper fastening block.
For convenient for operation, fastening assembly further includes the handle affixed with screw rod bottom.
Upper shell component includes upper housing and the upper cover for being removably connected to upper housing top open part, under lower shell component includes
Shell and the lower cover being removably connected at lower case bottom opening, upper housing are articulated in lower case, set in upper housing one end
There is the upper lock chamber for installing fastening block, is equipped with the lower lock chamber for placing u-bracket in lower case corresponding position.
Taking energy sampling component includes being mounted on the intracorporal upper core component of upper casing and upper Rogowski coil, being mounted on lower case pair
The lower core component and lower Rogowski coil that should locate, are covered with upper shielding case in upper Rogowski coil, in the case where lower Rogowski coil is covered with
Shielding case, upper core component are detachably connected by several screws being arranged symmetrically with upper housing, above and below upper housing and lower case
It is in a closed ring shape that docking drives upper core component and lower core component to dock up and down.
Linked clamping plate is equipped with above upper core component, screw passes through linked clamping plate and is threadedly coupled with upper housing, upper core
Component is installed between linked clamping plate and upper housing.
