Description
Technical field
The utility model relates to the sampling instrument in the power domain, and especially a kind of silicon rubber external insulation electrical equipment migration of hydrophobicity detects charged sampling instrument.
Background technology
With RTV coating and silicon rubber compound inslation electrical equipment is that the silicon rubber external insulation of representative has excellent anti-pollution characteristic; Safe operation for a long time in heavy dirt, high humidity environment; It is in the widespread use of electric system; Effect in short-term, low reliability, expensive, big workload that the anti-pollution flashover work of power equipment external insulation is fallen behind by tradition have been promoted, to modern advanced long timeliness, high reliability, low cost, little workload direction fast transition.
Though a large amount of operating experiences have fully shown the silicon rubber external insulation and have had excellent anti-pollution characteristic, for a long time, the anti-pollution characteristic of silicon rubber external insulation is still rested on the perceptual knowledge level, reason and mechanism problem are not well illustrated.Therefore, in the application and overall process technical management of silicon rubber external insulation, still need carry out electric property to the silicone rubber coating of electrical equipment surface coverage and follow the tracks of.
At present electrical equipment surface silicon rubber coating being carried out the unique method that electric property follows the tracks of is that electrical equipment is had a power failure; The filth that its surface is accumulated is carried out migration of hydrophobicity and is detected, but the equipment that causes thus has a power failure, equipment availability reduces, the reduction of user dependability etc. has huge adverse effect to the highly reliable operation of electric system.
Summary of the invention
The purpose of the utility model is to provide a kind of reasonable in design, scientific structure, easy to manufacture, safe in utilization; Especially can under situation about not having a power failure, carry out sample analysis, confirm that the silicon rubber external insulation electrical equipment migration of hydrophobicity of the electric property of equipment surface coating detects charged sampling instrument.
The purpose of the utility model is achieved in that
A kind of silicon rubber external insulation electrical equipment migration of hydrophobicity detects charged sampling instrument, it is characterized in that: comprise insulating bar, whirligig and sampling subsides, and the coaxial leading section that is installed in insulating bar of whirligig, the outside surface that is installed in whirligig is pasted in sampling.
And described whirligig is an insulation bearing.
And, two geometrical clamps are installed on the described whirligig, the outside surface that is arranged on whirligig through these two geometrical clamps is pasted in sampling.
And described insulating bar is made up of the quarter butt of one group of coaxial engagement.
The advantage and the good effect of the utility model are:
1, this charged sampling instrument is pasted by insulating bar, whirligig and sampling and constitutes, the coaxial leading section that is installed in insulating bar of whirligig, and the outside surface that is arranged on whirligig is pasted in sampling.Move insulating bar; Sampling on it is pasted to glue and is got filthy sample; And the body of rod and whirligig all adopt insulating material to process, so this sampler can carry out sampling and testing under situation about not having a power failure, improved equipment available rate, ensured the reliability of user power utilization.
2, the sampling of this charged sampling instrument is pasted and is fixed by geometrical clamp, this fixed form simple and fast, and be convenient to the replacing of sampling and pasting.
3, the insulating bar of this charged sampling instrument is made up of the quarter butt of a plurality of coaxial engagements, can be different when taking a sample operation according to the electric pressure of measured equipment, and the quarter butt of choosing right quantity is assembled into different length and meets the insulating bar of safety requirements.
4, insulating bar is made up of the coaxial engagement of a plurality of quarter butts, and it is not only easy to assembly, use is flexible, and the transportation that is easy to carry, and uses when especially being fit to go out operation.
5, the utility model be a kind of reasonable in design, easy to use, can improve capacity utilization, ensure the charged sampling instrument of user power utilization reliability; Use this sampling instrument can be under situation about not having a power failure; Sample analysis is carried out in filth to accumulate on the silicone rubber coating surface of electrical equipment; Confirm the electric property of equipment surface coating, this sampling instrument apply the highly reliable operation that helps guaranteeing electric system.

Embodiment
Be described in detail the embodiment of the utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit the protection domain of the utility model with this.
A kind of silicon rubber external insulation electrical equipment migration of hydrophobicity detects charged sampling instrument, and its innovative point is: comprise insulating bar 3, whirligig 1 and sampling subsides 2, the coaxial leading section that is installed in insulating bar of whirligig.
The outside surface that is installed in whirligig is pasted in sampling, and its concrete structure is: two geometrical clamps 4 are installed on the whirligig, and the outside surface that is arranged on whirligig through these two geometrical clamps is pasted in sampling.Whirligig shown in the present embodiment is an insulation bearing.
Insulating bar is made up of the quarter butt of one group of coaxial engagement, can be different during practical operation according to the electric pressure of measured equipment, and the quarter butt of choosing right quantity is assembled into the insulating bar of different length.
The use step of the utility model:
The first step: according to the electric pressure of measured equipment, confirm that insulating bar uses length, effective length must not be less than length safe in utilization;
Second step: the filthy sampling subsides of neutrality neatly are fixed on the whirligig, use the geometrical clamp secure both ends;
The 3rd step: testing tool is rotated the position visit to institute sampling electrical equipment full skirt position, the sampling veneer is towards desiring sampling point;
The 4th step: slightly exert oneself downwards, make rotating head on full skirt, roll, must not move forward and backward therebetween;
The 5th step: after treating the sticking filth of gathering down, retraction tool;
The 6th step: will sample to paste and take off, keep, to be detected.
