The invention applies to the technical field of transformer maintenance, and provides an online parameter measurement system for transformer insulation oil. The system comprises an oil sample detector, two temperature sensors and at least one flexible tube connected to sampling joints of a transformer, wherein the two sensors are inserted into an upper sampling point and a lower sampling point of the transformer respectively and send received temperature data to the oil sample detector; a prefiltration device is arranged on each flexible tube; on-off valves are arranged on the sampling joints of the transformer; the oil sample detector comprises a casing and a panel covering the casing, and an oil storage bottle, a gas pump, an oil sample probe device, a main control panel and a power supply unit are arranged in the casing. An online measurement scheme for the transformer insulation oil is provided, so that main key indexes of the transformer oil can be measured in the field, the quality of the transformer oil is reflected truly, and the defect of measurement errors caused by environment and human factors is overcome; and further, by means of the system, the service life of the transformer can be prolonged, the reliability of the transformer is improved, and the operation cost is reduced.

The invention relates to a stable programmer with a temperature control function for software testing. The device comprises a main body and a programming card seat. The device further comprises at least two reinforcing mechanisms and at least two temperature control mechanisms. The reinforcing mechanism comprises a housing, a pressing plate, a lifting rod, a supporting sleeve, a spring, a suctioncup and two connecting assemblies. The temperature control mechanism comprises a top plate, a lifting sleeve, a fan, a driving assembly, at least two exhaust ports and at least two dustproof nets A programmer can be adsorbed on a desktop through the reinforcing mechanism. Therefore, the probability that the programmer falls off from the desktop is reduced. Compared with the prior art, the programmer has the advantages that the probability of damage to the programmer is reduced. The practicability of the programmer is improved, the temperature in the programmer can be adjusted through the temperature control mechanism. The programmer operates within the normal working temperature range, the working performance of the programmer is improved, and the practicability of the programmer is further improved.

The invention provides PCV2-PRV (porcine circovirus type 2-porcine pseudorabies virus) two-temperature type double PCR (polymerase chain reaction) detection primers and a diagnosis method thereof. The primers comprise a PCV2 primer pair and a PRV primer pair, wherein the PCV2 primer pair comprises an upstream primer PCV2-F1 and a downstream primer PCV2-F2; the PRV primer pair comprises an upstream primer PRV-F3 and a downstream primer PRV-F4. Key parameters of the two-temperature type PCR are explored, so that PCV2 and PRV can be detected synchronously, and the primers are simple to operate, low in technological requirement, low in cost, time-saving and labor-saving, have good specificity, sensitivity and stability and are suitable for clinical popularization and application.
