The invention provides a full-sealing oil sampling device and method for a transformer bushing. The full-sealing oil sampling device for the transformer bushing comprises a device body and a cone; a first oil port, a second oil port, a first gas port, a second gas port and a third gas port are formed in the device body; the first oil port extends into the transformer bushing, and the second oil port is connected with a sampling device; the first gas port leads to the inside of the transformer bushing, and the second gas port and the third gas port are connected with a vacuum pump and a nitrogen bottle respectively. In the oil sampling process, nitrogen is introduced into the transformer bushing, a certain positive pressure is formed in the bushing, and under the action of the positive pressure, an oil sample automatically flows into the sampling device; in the oil replenishing process, the transformer bushing is vacuumized, a certain negative pressure is formed in the bushing, and under the action of the negative pressure, oil automatically flows into the transformer bushing. Thus, the device ensures the sealing of the whole sampling process and realizes full-sealing sampling.

The present invention relates to an expansive cell composition for an electric rock destruction. The expansive cell composition is fabricated using metallic salt that is oxidation agent, metallic powder, and hydrocarbon compound. The composition is uniformly mixed at a certain composition ratio so that the composition is stably expanded by a high temperature heat and impact wave energy generated when a high current is fast discharged with respect to a metallic wire. A hybrid-oxidation and combustion reaction is obtained, in which a hybrid-oxidation and combustion reaction is performed, in which a flame oxidation reaction of metallic salt and metallic powder and a combustion oxidation reaction of a hydrocarbon compound by the flame oxidation reaction are mixed. The rocks are destructed by generating a vapor expansion force matching with a fracture ability class of rocks. Low noise and vibration are obtained when destructing rocks, and broken pieces of rocks do not fly away. Any change in quality does not occur in the composition according to the present invention.
