Abstract: A method for fault location to single-terminal traveling wave includes steps as follows. Step (a): recording a waveform of a traveling wave signal of disturbance by a traveling wave device when a line disturbance occurs. Step (b): performing a phase mode transformation on the waveform recorded by the step (a), so as to obtain components of line mode and zero mode of a fault initial traveling wave, and performing a wavelet transform to decompose the components of the line mode to obtain singularities in the waveform of the traveling wave. Step (c): calculating a wavefront slope k of the components of the line mode of the fault initial traveling wave.

Abstract: An electromagnetic clutch of a brushless control-by-wire centrifugal ball arm engagement device includes a brushless electromagnet, a thrust pressing disc, a driven inner-spline hub, a control-by-wire drive disc, a centrifugal ball arm hollow disc, centrifugal ball arm pins, centrifugal ball arms, centrifugal balls, a magnetic conductive force transmitting disk, a drive shaft; once the brushless electromagnet is energized, the centrifugal ball arms and the centrifugal balls each make a circular motion around the centrifugal ball arm pin outwardly along the smooth surface of the thrust pressing disc by the action of centrifugal force produced by them when rotating with high speed. The component of the centrifugal force in the direction of the central axis of the centrifugal ball arm hollow disc drives the thrust pressing disc to compress the outer-spline-groove steel sheets and the inner-spline-groove friction discs with each other, which makes the clutch engaged.

Abstract: The present invention relates to a method for automatic identification of an application network topology for power distribution network control which belongs to the field of electric power automation. The method comprises the following steps: 1. statically configuring attributes of a switch; 2. determining, by a power distribution network intelligent terminal STU, whether a query trigger condition is satisfied; 3. sending, by an inquirer, a query command to initiate the query into an application network topology; 4. replying to the query command; 5. receiving the query command; 6. checking the integrity of the switch attribute information; and 7. forming an application network topology. The present method for automatic identification of an application network topology for a power distribution network control has few calculations and can be executed with high speed, ensures the integrity and reliability of information, and is particularly suitable for distributed intelligent control of the power distribution network. The establishment of the application network topology is distributed to each power distribution network intelligent terminal STU, thus reducing heavy calculation, and is suitable for applications having relatively few embedded system software and hardware resources.

Abstract: An automatic uncoupled charging device includes a control system, a power system, a charging system, and an auxiliary system. The control system is equipped with a programmable circuit to control a screw speed. Explosives are charged into a container through manual handling or flowing from a mixed explosive vehicle. Explosive bags with different diameters are installed at the bottom of a discharge port. The device is set to start with one click, and the screw drives the explosive into the bag, achieving uncoupled charging. An automatic uncoupled charging method applying to the automatic uncoupled charging device not only reduces labor intensity, achieves fast charging, improves labor efficiency, but also achieves the goal of “mechanization reducing personnel”, further advancing towards the essential safety of blasting construction.
