A split-type device for measuring rock mass deformation under high hydraulic pressure and a construction method and use thereof. Main components of the device include a metal measuring rod, a magnetic iron core, a shell, a waterproof coil framework, a coil, a tail accessory, a cable clamp, a cable, a signal processing bin, etc. Main electronic components are treated by adopting the all-metal shell and a vacuum particle sealing double-layer sealing process, and have hydraulic pressure resistance of 5 MPa or above. Measurement signals feature centralized processing, digitization and dual utilization of signals, i.e., after data of a plurality of sensors is processed in an electronic bin and then digitized signals are connected to an independent reader outside the bin or a centralized acquisition device for in-situ tests.

Split-type device for measuring rock mass deformation under high hydraulic pressure and construction method and use thereof

A device for simulating intermittent arc grounding faults in a power distribution network includes a sliding rail, a first and a second support frames, an insulated electrode disk, and an electrode disk motor. The first support frame is fixed on the left side of the slide rail, and the position of the second support frame relative to the first support frame can be adjusted through the sliding rail. The second support frame is provided with an electrode disk motor for driving the insulated electrode disk to rotate. An upper and a lower conductive bars are installed on the first support frame, their adjacent ends provided with an upper and a lower arc-shaped conductor sheets, and the insulated electrode disk having two circles of conductive pillars is located between the conductor sheets. The conductor sheets are respectively installed on the side of the conductive bars close to the conductive pillar.
