Preferably, the first pulse detection bar and the junction of the second pulse detection bar and installing plate are all provided with absolutely Edge set.

Preferably, the outer surface set rubber sleeve of the handle.

Preferably, audible-visual annunciator is installed on the A-T impact types pulse instrument.

Preferably, the middle position of the chamber door is provided with observation window.

Compared with prior art, the beneficial effects of the utility model are：

(1) the power cable fault prior-warning device uses A-T impact type pulse instruments, can realize electromagnetic pulse failure automatically Positioning, light emitting diode indicator show failure orientation, also have defect center instruction, allow to " can also see " electricity in the dark Magnetic field impulse involves its direction, convenient observation and detection.

(2) the power cable fault prior-warning device impact type pulse signal is gone out in the form of the bargraphs of readability now Existing, allowing you, this just simplifies, accelerates fault location, and super orientation sound wave detector passes no matter can easily interpret blueprints day and night The information of more abort situation is sent, accelerates the speed of detection.

(3) the power cable fault prior-warning device overall structure is simple, it is possible to achieve the power cable to being embedded in underground It is detected, improves the practicality of device.

(4) the power cable fault prior-warning device is easy to use, and device need to be only fixed on the upper of power cable by when use Detection can be achieved between the soil of side, easy to promote the use of.
