I. Overview

Because of the extreme complexity of the power cable laying environment,

pinpointing points has always been a critical step in cable fault testing. Even with an

accurate rough side distance, it is difficult for us to locate quickly and accurately due to the

influence of the external environment. The HZ-B cable fault precise locating instrument is

a portable, ultra-quiet, visual impact discharge receiving precise locating instrument. It is

specially used in conjunction with a high-voltage impact generator. It adopts leading

background intelligent noise reduction and sound tracking new technologies to achieve

Continuous optimization, perfect sound effect, record the characteristic sound of impact

discharge and the signal that will be picked up at the scene to achieve comparison.

When HZ-B uses continuous impulse discharge at the front end, the impulse

discharge sound of the fault point within the distance of the thick side propagates on the

ground above the cable and is recorded by the ground-penetrating sensor on the ground.

The distance between the detection point and the real fault point of the cable can be

obtained by the method of impact discharge noise volume.

II. Technical characteristics

Ultra-quiet noise reduction processing, excellent sound quality of discharge sound, the

background is quieter, monitor earphones are used to quickly and reliably locate the fault

location.

Using ultra-quiet technology and BNR intelligent background noise reduction

technology, you can adjust the impact discharge volume.

Molded design of a special self-falling ground sensor, and equipped with a soft

pavement, hardened pavement, lawn sensor joint.

Reliable imported connectors are selected to ensure the purity of the sound, and the

height-adjustable probe handle is humanized, which is very suitable.

III. Technical parameter:

Sensor dynamic range: sound channel> 104dB.
