Abstract
The invention relates to the technical field of transformers, in particular to a transformer oil sample collection device. The transformer oil sample collection device comprises an oil sample valve, wherein the oil sample valve is welded to a steel plate with a hole in the center, the steel plate is welded to a steel tube, the steel tube is welded to a flange with holes in four corners, and the flange is fixed to a blind hole of an adjusting flange through bolts. The oil sample valve plays the role of a switch, controls and adjusts the outflow size of a transformer oil sample and provides a connecting port for a dedicated sample storage device. The applied adjusting connecting port multi-portion transformer oil sample collection device can be connected with the valve closest to a fault point. No matter how large the valve is, the device can be connected with the valve by being connected with one or more adjusting flanges in a combined mode. The applied adjusting connecting port multi-portion transformer oil sample collection device can immediately collect transformer oil samples nearby the fault point and save 4-8 hours of time cost every time.
Description
Technical field
The present invention relates to transformer technology field, specifically relate to a kind of transformer oil sample harvester.
Background technology
Transformer oil is the primary insulation medium in Large and Medium-sized Power Transformer, and transformer oil has the function of transmission of information in transformer.After discharge fault appears in inside transformer, the transformer oil near trouble spot can be decomposed and produce the information of fault characteristic gases acetylene and supplemental characteristic gas hydrogen, methane, ethene, ethane.The one-tenth grading information detecting its failure gas is carried out, immediate analysis and tracing trouble character by the oil sample gathering transformer oil near trouble spot in time.
At present, the same upper lateral part on the same long axis direction of middle-sized transformer, middle part, bottom are fixed welding and are arranged that three transformer oil samples gather valves, are used for carrying out the collection of transformer oil sample.General about 5m × 2m × 2m to the 10m × 5m × 5m of the volume length of big-and-middle-sized transformer × not etc., existing transformer oil sample valve arranges it is to gather other position transformer oil sample of transformer in time like this, especially, when breaking down in the position far away apart from transformer oil sample valve, the oil of abort situation after 4 to 8 hours be waited just to be diffused near oil sample valve.This gives the very large puzzlement and waste of producing normally and bringing.Directly open the sampling method that the nearest valve sampling in trouble spot does not meet again the enclosed sampling process that national standard requires, and oil spout pollutes and wastes.
Summary of the invention
For the technical matters existed in prior art, the object of the present invention is to provide a kind of transformer oil sample harvester, the feature of various (conventional Ф 50mm, Ф 80mm, Ф 100mm, Ф 150mm tetra-kinds) specification valve is arranged according to transformer surrounding, design and produce the transformer oil sample harvester be connected with various valve, collect the transformer oil sample at each position to greatest extent in time.
To achieve these goals, the technical solution adopted in the present invention is: a kind of transformer oil sample harvester, comprise oil sample valve, oil sample valve is welded on the steel plate of center drilling, Plate Welding is on steel pipe, steel-pipe welding is on the flange of corner perforate, and flange is bolted in the blind hole of regulating flange; Oil sample valve, plays the effect of switch, controls and regulates transformer oil sample to flow out uninterrupted, and providing the interface with Special sample storer.
The central punch of steel plate is communicated with oil sample valve and coordinates, and steel plate external diameter 60mm welds with steel pipe is concentric; Thickness is 6mm; It is 20mm that center turns bore dia, welds with oil sample valve is concentric.
The internal diameter of steel pipe is 50mm, and thickness is 3mm, is highly 50mm, welds with flange is concentric.
The steel plate thickness of flange is 8mm, and surfacing meets seal request, the square in length of side 125mm, and the diameter of center drilling a is 50mm, corner opening diameter 14mm, and same lateral opening distance is 88mm; Flange is directly connected with the valve of Ф 50mm; Can be bolted with one or more regulating flange, be applied on the valve of other more large gauge.
The steel plate thickness of regulating flange is 20mm, the length of side matches with the butterfly valve that will be connected, the diameter of center drilling b is 50mm, the diameter of corner perforate is 20mm, the same lateral opening distance of corner perforate and the valve bolt-center that will be connected are apart from matching, the seal groove that one side has 2mm dark places sealing strip, and with oil sample valve Flange joint, one side is that plane is connected with transformer side valve.
Transformer oil sample harvester of the present invention, its beneficial effect shows:
1. application regulates interface multiple location transformer oil sample harvester, and valve that can be nearest with trouble spot is connected.No matter valve specification is much, can be attached thereto by one or more regulating flange that is connected.
2. application regulates interface multiple location transformer oil sample harvester, and the transformer oil sample near instantaneous acquiring to trouble spot, saves the time cost of 4 ~ 8 hours at every turn.
3. application regulates interface multiple location transformer oil sample harvester, sampling process, oil sample completely and external environment isolate, meet the sampling requirement of national standard completely.
4. application regulates interface multiple location transformer oil sample harvester, the oil spout caused owing to directly opening valve can be avoided to waste and pollute, saved production cost.
