A system and a method for an integrated test on a primary-secondary pole-mounted breaker. The method includes: establishing an electrical connection between the system and the primary-secondary pole-mounted breaker; establishing a communication connection between the system and the primary-secondary pole-mounted breaker; applying, by the system, a voltage signal and a current signal to the primary-secondary pole-mounted breaker through the electrical connection, to generate a voltage and a current on the primary-secondary pole-mounted breaker; collecting, by the system, signals of the voltage and the current fed back from the primary-secondary pole-mounted breaker through the communication connection; performing, by the system, an integrated accuracy test and an integrated protection test; outputting a test result of the accuracy test and a test result of the integrated protection test to the industrial control machine, to generate the test report. A blind zone in quality control of primary-secondary pole-mounted breakers is eliminated. Efficiency is improved in testing primary-secondary pole-mounted breakers.

System and method for integrated test on primary-secondary pole-mounted breaker

The present invention provides a reagent mixing device, which comprises a driving device, a transport device and a rotating part, wherein the transport device comprises a conveying mechanism for conveying a reagent kit and a mixing mechanism for mixing a reagent; the conveying mechanism is driven by the driving device to move relative to the mixing mechanism; the rotating part and mixing mechanism are in transmission matching; the conveying mechanism and the mixing mechanism are sleeved with each other to form a bearing structure. The present invention further provides a reagent mixing method. The reagent mixing device is small in size, smart in structure, easy to assemble and low in manufacturing cost. The reagent mixing method provided by the present invention is simple and reliable, high in overall operation reliability, and has very high application values in such analysis and test fields as full-automatic chemiluminescence immunoassay analyzers and biochemical analyzers.

The present invention relates to a heat preservation shell () for an analyzer. At least one liquid passage () for conveying the liquid is embedded in a shell wall of the heat preservation shell. The liquid passage () is embedded in the shell wall of the heat preservation shell (), on one hand, the liquid transported or preserved in the liquid passage is subjected to the heat preservation function of the heat preservation shell, so that the liquid transported or preserved in the liquid passage () maintains the preset temperature, thereby avoiding the influence of the external environment temperature on the transported liquid; and on the other hand, the space of the shell wall of the heat preservation shell is effectively utilized, the situation that various liquid pipelines are intricately distributed inside or outside the heat preservation shell () is avoided, thereby increasing the space utilization rate.

Provided is a container autorotation device and method. The container autorotation device comprises a conveying rack used for conveying a plurality of containers, at least one container base connected therewith and comprising a container clamping end and a driving end, and a driving component used for driving the container base to autorotate and comprising a motor and a clamping part driven by the motor. A slot matched with the driving end is formed in the clamping part such that when the driving end moves into the slot and stay, the driving end is driven by the clamping part to rotate. The slot in the clamping part is designed so that the driving end is pushed against the slot when entering the slot and rotating in the slot. Autorotation is achieved with mutual cooperation between the clamping part and the driving end.
