Patent JP-H0313873-A (JP)
Title: Apparatus for detecting accident occurrence point
Inventor: FUTAJIMA HIDEAKI
IPC: G01R31/08
Filed: 1989-06-12
Abstract: PURPOSE:To calculate the accident occurrence point of an object spreading on a surface at a short distance by catching the electromagnetic wave and a sound wave generated from the power equipment in a substation at the times of earth and short-circuit by one antenna and three or more microphones and measuring the propagation times of both of them. CONSTITUTION:When an accident occurs, an electromagnetic wave and a sonic wave are simultaneously generated at an accident occurrence point. When one electromagnetic wave detecting antenna AT and three microphones M1 - M3 are arranged at a certain interval, the sonic wave generated at the accident occurrence point is detected with time differences T1 - T3. Since the electromag netic wave is extremely faster than the sonic wave in propagation velocity, the time from the occurrence of the accident to the detection of the electromag netic wave may be considered to be zero. The aforementioned time differences are measured by a time difference detection circuit and the accident occurrence point is calculated by a processing apparatus (computer). The accident occur rence point is calculated from formulae (1), (2) (wherein U is sonic velocity and T1, T2 and T3 are the arrival times of sound from an accident occurrence point to respective microphones M1, M2, M3).
