Abstract: A method for determining a consistency coefficient of a power-law cement grout includes: determining a water-cement ratio of the power-law cement grout; according to engineering practice requirements, determining a time required to determine the consistency coefficient of the power-law cement grout; and obtaining the consistency coefficient of the power-law cement grout. The method is accurate and reliable, requires less calculation, etc.; and has very high practical value and popularization value in environmental protection and ecological restoration.

Abstract: An exemplary automatic hi-pot test apparatus (20) includes a high voltage supply (21), a transmission device configured for transmitting an electronic device (26) to be tested, a connecting device electrically connected to the high voltage supply and configured for moving and electrically connecting with or electrically disconnecting from the electronic device, a controller (28) for controlling the connecting device and the transmission device, and a detector (27) for detecting the presence of the electronic device. When the detector detects the presence of the electronic device, the detector sends a corresponding detecting signal to the controller, such that the controller stops the electronic device and drives the connecting device to electrically connect with the electronic device whereby a hi-pot test can be performed.

Abstract: An exemplary testing apparatus (200) for testing electronic device (280) includes a workbench (210), a conveyance board (221) for supporting the electronic device to be tested and a testing device (270). The conveyance board is slidably positioned on the workbench. The testing apparatus further includes an automatic detection device (250), a high voltage connector (241) and an automatic controller (290). The automatic controller receives a signal sent by the automatic detection device and sends an instruction to control the operation of the high voltage connector to connect a plurality of signal channels. The testing apparatus is safe and can reduce the cost.

Abstract: An exemplary hi-pot testing device (2) includes a testing table (20), a transfer table (21) movably supported on the testing table and configured to support a product (200) to be tested, and a hi-pot testing signal generator (27) under the testing table. The transfer table includes a top surface and a bottom surface, a first current input portion (23) at the bottom surface (202), a first power connector (234) embedded at the top surface, and electrically connecting to the first current input portion, and a first signal cable connector (25) arranged on the top surface. The first signal cable connector is grounded and configured to enable the product to be grounded. The hi-pot testing signal generator is configured to electrically connect with and electrically disconnect from the first current input portion of the transfer table.

Abstract: An automatic transmission apparatus (200) includes a transmission floor (210), at least one board (220), a first stopping unit (230), a second stopping unit (240), a plurality of inspecting units (250, 251, 252), and a controlling unit (260). The transmission floor has a plurality of rollers positioned at two long sides thereof. The at least one board is positioned on the rollers. The first and seccond stopping units are positioned along a path of movement of the at least one board along the transmission floor. The second stopping unit is along a predetermined distance from the first stopping unit. The inspecting units generate a plurality of inspecting signals according to a current position of the board. The controlling unit receives the inspecting signals and controls the first and second stopping units according to the inspecting signals. The first and second stopping units stop the at least one board from moving.
