The base comprises a positioning disc and a triangular positioning frame arranged at the bottom of the positioning disc. The supporting rod is installed on the base. The top suspension arm arranged at the top of the supporting rod is in the form of a capped u-shaped rod. Compared with the prior art, the general insulating bracket has the advantages of good insulating property, strong versatility, convenient usage and the like.
Description
Technical field
The utility model relates to a kind of insulating support, especially relates to the general insulating support of a kind of cable variable-frequency series-resonance test.
Background technology
Existing 110kV and above high-voltage cross-linking polythene cable completion test adopt the variable-frequency series-resonance test usually, need use equipment such as reactor, excitation change when using this technological means, because these equipment volume are big, Heavy Weight, be difficult to settle in the general transformer station, so need select spacious zone, region to settle at the trial, therefore when testing, need finish being connected of tested cable and testing equipment by the lead-in wire of long distance.In installing lead-in wire process, can face the puzzlement of problems such as long distance, many landform, many corners, often expend too much time and manpower.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of cable variable-frequency series-resonance test general insulating support for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: the general insulating support of cable variable-frequency series-resonance test, it is characterized in that, comprise base, support bar, top suspension arm, described base comprises the triangle locating rack that positioning disc and positioning disc bottom arrange, described support bar is installed on the base, described top suspension arm is installed in support bar top, and described top suspension arm is adds a cover U-shaped shape.
Positioning disc center stationary magazine creel on the described base, the support bar bottom is inserted in the stationary magazine creel fixing.
The triangle locating rack is 120 degree by three channel-section steels and distributes and to be welded on the described base, and each channel-section steel top is provided with two relative legs, and each leg is provided with fixed orifice.
Described support bar is multi-joint telescoping formula support bar, and each saves stationary positioned cover between the support bar.
Described support bar is provided with for folder and establishes the position, hole that printed line is used.
Described support bar top is provided with draw-in groove and the fixed orifice of fixed top suspension arm.
Described top suspension arm comprises the U-shaped arm that crossbeam and crossbeam are divided into, described crossbeam one end is provided with fixture block, fixture block is provided with screw, and described fixture block inserts in the support bar top draw-in groove, and passes screw on the fixture block and the fixed orifice on the support bar is fixed by bolt.
Compared with prior art, the utility model need possess following major function:
1) insulating property: satisfy 220kV and 110kV alternating voltage minimum safe distance.
2) versatility: be suitable for all kinds of transformer stations topographic features, (the 110kV test lead adopts two bare copper wire (sound equipment line) 5mm can to hang (support) all size test lead and corrugated tube
2, wire length is generally less than 30m; 35mm is adopted in 220kV test lead maximum cross-section
2Bare copper wire, wire length is generally less than 45m; Abominable as environmental baseline, or cooperation office knocks off when doing, at 35mm
2It is that 250mm aluminium foil corrugated tube uses as shielding that bare copper wire needs to install additional diameter outward).
3) portability: support should be designed to detachably, assemble style, and single-piece length should be controlled in 2m, and the single-piece width should not surpass 0.25m.
4) support will be controlled being suitable for of metalwork, is particularly hanging (support) test lead place, unsuitable suitable metal material, and the floating potential that produces when withstand voltage to reduce influences the trial target prime factor.
