Description of the development:
()
The receiver is used: to determine the electroacoustic method of damage to underground power cables during a spark breakdown of the veins on the shell (MP to determine the electroacoustic method of damage to underground power cables for a deaf single-phase closure of the cable core to the sheath (type of IP); MP of the type of GOZ); for solving electro-acoustic method of selecting a specific cable from a bundle of open cables; the locations of poor contact between the shell and the cable clutch; determining the cable route and finding the fault location by induction method; determining the depth of the cable; the location of the leak in the insulation of the cable jacket made of cross-linked polyethylene or gas pipeline by a potential method on a constant and alternating voltage; Determination of the leakage location in the insulation of the low-voltage cable veins on the ground potential method. The receiver is designed to work in the mobile electrotechnical laboratories, which include the generator of electroacoustic shock waves (GAUV) with the following parameters: capacity of the drive to determine the location of damage of the type GOZ-300-400 mkF with charging voltage (5-10) kV; the pulse frequency is 0.2-1 Hz. This version of the GCSE is suitable for searching for damage of the type of GOZ. To determine the damage of the type of IP - the storage capacity can be reduced to 1-5 mkF. In addition, an audio frequency generator with a power of at least 20 W with a frequency of 160 to 11000 Hz (for example, the GZCH-2500 generator) is required to determine the cable routing route on the terrain. To locate faults in interphase-type cables, an audio frequency generator (frequency 160-11000 Hz) with a power of 100 W (for example, GZCH-2500) is required.
