Description
Technical field
The utility model relates to two gap determinators between the face, particularly adopts the measurement mechanism of laser measurement transformer neutral point gap size.
Background technology
The transformer neutral point gap size is confirmed according to the transformer neutral point dielectric level.For operating transformer, safety explicitly calls for neutral point to be regarded as charging equipment.If the incomplete in-site measurement neutral point clearance distance that needs of source book then is difficult in direct measurement in service, generally can only combines main transformer to have a power failure and carry out.
The utility model content
The purpose of the utility model provides a kind of transformer neutral point gap of directly measuring that can be in operation and checks device.
This novel purpose is achieved in that a kind of transformer neutral point gap check device; Comprise first, second generating laser, four legs are installed under the base plate, putting on the base plate has vertical equity appearance and lateral level; Left and right support is fixed on plate upper surface; The cross section is that the guide rail of rectangle is installed in rotation on respectively on the left and right support through the left and right end axle on the guide rail, and guide rail is provided with scale, and the guide rail end face is parallel with plate upper surface; Clamping screw is screwed on the left socle, and the screw-threaded engagement on clamping screw and the guide rail left end shaft or clamping screw be crimped on guide rail left end shaft on; Said first generating laser is installed on the left part end face of guide rail, and said second generating laser is installed on the slide block end face, and slide block is linked on the guide rail slidably.
The structure of above-mentioned four legs is: base is welded on the plectane by the internal thread tube coupling and constitutes, and screw rod is screwed on the internal thread tube coupling of base.
The principle of work of the utility model is: adjust surveying instrument to horizontality through vertical, lateral level, adjustment instrumental azimuth and guide rail are restrainted laser until two of two generating lasers and are impinged upon simultaneously on the rod of neutral point gap; Turn clamping screw fixed guide, sliding slider is slided on the rod of neutral point gap by the laser beam that the generating laser that is fixed on the slide block is launched; When laser beam breaks away from the gap rod; Read measurer numerical value, once more along the equidirectional sliding slider, when laser beam impinges upon on the rod of gap once more; Reading numerical values once more; The principle of utilizing parallel four limit row opposite side to equate can get, and the difference of the number that reads for twice is the neutral point gap length, and satisfies power transformer neutral point device measuring error requirements.
Guide rail and neutral point gap copper rod that device is checked in the neutral point gap form two parallel lines, and the generating laser vertical fixing is on the guide rail end face, and the transmitter emitted laser is perpendicular to neutral point gap copper rod place straight line.Generating laser is the distance that laser is walked in the distance of sliding on the guide rail on the straight line of neutral point gap copper rod place, calculate laser in the neutral point gap during two copper rod end points the difference of gauge reading be neutral point clearance measurement value.
The beneficial effect of the utility model is:
1, novel, practical, solved the problem of transformer neutral point clearance measurement.
Therefore 2, this device can be in operation the transformer neutral point gap is measured, and need not contact any position of transformer, does not need transformer to have a power failure, and can measure at any time to check gap size and whether satisfy configuration requirement, helps the safe operation of transformer.
