Description

A kind of jointing clamp
Technical field
The utility model relates to power system device and detects power tool, particularly relates to a kind of jointing clamp.
Background technology
Power transformer is one of visual plant in electric system, we regularly must to have a power failure test to its various parts, with the requirement checking its properties whether to meet " power transmission and transformation equipment state overhauling testing regulations ", Timeliness coverage threatens the defect of safe operation.Shorten transformer field Diagnostic Time, in time for the formulation of Condition Maintenance Method of Transformer strategy provides data supporting.A current transformer interruption maintenance test period is about 9 hours, leave the transformer test time for and only have 6 hours, real transformer test period is about 7 hours, occupy the time that transformer cleaning checks, transformer cleaning is caused to check careful not, have impact on cleaning quality, too increase transformer power off time simultaneously, have impact on overhaul efficiency.
The statistics of each period of averaging time of 220kV transformer test work shows, the winding D.C. resistance test duration accounts for 35% of transformer test used time overall length, and the winding D.C. resistance test duration is long.And disconnect the direct resistance metering line time used and account for 60% of the main transformer winding D.C. resistance test duration.
Be described for a phase transformer winding D.C. resistance test.During measuring resistance, because transformer high-voltage bushing is at about 3 meters, need climbing bushing to carry out disconnecting line, some transformers sleeve pipe and level angle are comparatively large, not only climb difficulty but also there is induced electricity sometimes, having certain risk.If use high-altitude bucket arm vehicle can waste the more time.Use High-Voltage Insulation bar to carry out wiring, direct resistance metering line wire clamp is clipped on bar head, is connected to sleeve extracting end with High-Voltage Insulation bar.After High-Voltage Insulation bar altitude combination, length can reach sleeve pipe height, can reduce test period.But connecting test line is not firm like this, p-wire is little with equipment wire clamp surface of contact area, affects test result, is not easy operation in addition on ground.
Utility model content
The purpose of this utility model is exactly to solve the problem, and proposes a kind of jointing clamp.
To achieve these goals, the utility model adopts following technical scheme:
A kind of jointing clamp, comprise control lever and be arranged on the binding clip on control lever, described binding clip is provided with capable of opening and closing upper jaw and lower jaw, be provided with the self-locking device making binding clip self-locking in described control lever, upper jaw and lower jaw are connected to p-wire respectively, described binding clip is fixed with camera, the surrounding of camera is provided with multiple LED light source, described camera is connected with control device by transmission line, and described control device is connected with display, and described LED light source is also connected with control device.
Described upper jaw and lower jaw are provided with insulating material, make can not conduct electricity between upper jaw and lower jaw.
Described control device comprises the button for controlling camera switch and regulates the bright adjustment button secretly of LED light source.
Described camera and LED light source are arranged on binding clip by The Cloud Terrace, and described The Cloud Terrace is connected with described control device, and described The Cloud Terrace can be controlled to carry out rotating or moving by control device.The adjustment of camera can be controlled by controlling The Cloud Terrace easily, to adapt to the optional position of on-the-spot transformer, completing the test of Transformer Winding direct current resistance easily.
Also comprise one to mate work telepilot with control device, to control the motion of The Cloud Terrace.
Described control lever comprises interconnective fixed bar and expansion link, and described binding clip is fixed on fixed bar, and described self-locking device is arranged in fixed bar, realizes the clamping of upper jaw and lower jaw and open by self-locking device.
Described p-wire one is testing current line, and one is voltage tester line.
Described p-wire is fixedly located on upper jaw and lower jaw by screw bolt and nut, facilitates the fixing of p-wire and takes off.
The beneficial effects of the utility model are:
When carrying out winding D.C. resistance test, p-wire i.e. current/voltage line have been fixed on binding clip, fixing test line that need not be extra again, the binding clip of jointing clamp can be adjusted to the angle roughly the same with wiring position by live view easily that utilize camera to take, substantially increase accuracy rate, conveniently carry out next step operation, visualization is high.During hanging wire, jointing clamp is leaned against on wiring position gently, then pull joystick of slowly exerting oneself, under the effect of self-locking device, jaw is clamped.When taking off jointing clamp, only the direction of control lever to jointing clamp need be promoted, jaw can be opened.
The routine test time of 220kV transformer can be reduced by the utility model, so that the hidden danger that Timeliness coverage equipment exists, ensure that the normal operation of transformer, for the safe operation of electrical network is laid a good foundation.Further, the use of this jointing clamp avoids contact that is directly personal and operational outfit, has stopped the possibility of getting an electric shock, and clearly can also see the actual conditions in high-altitude.
