    Abstract: An aqueous fire extinguishing agent and a preparation method thereof are provided, which are used for making a throw-type fire extinguisher. The aqueous fire extinguishing agent is composed of two compositions of A and B. The composition A is a fortified water added with a flame retardant (e.g., one or more of ammonium chloride, diammonium hydrogen phosphate and ammonium polyphosphate), a wetting agent (e.g., alkyl polyglycoside) and a colloid (e.g., polyacrylamide solution). The composition B is a regulator. After the composition A and the composition B are mixed, a discharge rate/speed of fire extinguishing substances is increased, so that an escape passage/route can be opened up quickly.

  • Patent number: 9720027
    Abstract: The invention discloses a fault point locating method of hybrid lines based on analysis of comprehensive characteristics of single-end electric quantity and transient travelling waves, which mainly includes steps: phase-model transformation; looking up initial time of failure; extracting timing window data after the initial time; searching a reflected wave from the fault point and a reflected wave from a demarcation point in the timing window; and judging properties of the reflected waves. After failure of a hybrid line with cable and overhead line, by identifying and comparing comprehensive characteristics of the reflected wave from the fault point, primary and secondary reflected waves from the demarcation point in the single-end transient voltage and current travelling waves, it is rapidly judged whether the fault point is located in the overhead line segment or the cable segment, which is used to assist in switching decision for line reclosing.
