Description

485 line fault finder

technical field

The utility model belongs to the technical field of power line fault finding tools, and relates to a 485-line fault finder.

Background technique

With the development of society, the use of the 485 line is becoming more and more perfect, which also increases the inspection and maintenance work in the later period.

The 485 line fault finder can simplify the on-site operation process, shorten the time used to detect the 485 bus fault of the electric energy meter during the construction and maintenance process, and automate the on-site operation. The detector has excellent performance, simple operation, easy to carry, intuitive LED light indication, and the detection result can be obtained directly with the state of the electric energy meter.

The 485-line fault finder of the prior art is provided with two detection lines, and the detection line is provided with two alligator clips with insulating sleeves, and the alligator clips are clamped on the line for detection. Although this device is widely used, there are many disadvantages: the test is a live test, although there is an insulating sleeve on the crocodile clip, but when connecting, the distance between the hand and the line is very close, and there is a possibility of electric shock due to static electricity and other reasons. The shell of the fault finder is provided with bolts, etc., which cannot be effectively insulated, and it is very dangerous to directly hold it by hand; during work, the alligator clips need to be clamped and removed back and forth, and some need to climb to work, which is very inconvenient.
