Embodiment 1

[0027] according to figure 1 A 485-line fault finder, including a finder 11 and a wire clip 3; the finder 11 is provided with a running light 13, a sending light 14, a receiving light 15, and a 645 receiving light 16, and a charging jack is provided at the back 12. There are two detection wires 5 connected by 485 adapters 9 on the front; a tapered wire hanging groove 8 is provided on the wire hanging clip 3; metal sheets are respectively arranged on both sides of the tapered wire hanging groove 8 2 and arc-shaped sheet 7; the other end of the arc-shaped sheet 7 is provided with an elastically connected spring 6; the metal sheet 2 is provided with an indicator light 1 connected by a wire; the wire hanging clip is provided with an insulating rod 4; The detection wire 5 passes through the insulating rod 4 and is connected to the metal sheet 2 in the wire clip 3 .

[0028] The insulating rod has a length of 50 cm and is hollow.

[0029] An insulating sheath is arranged around th...

Embodiment 2

[0039]485 detection LED light indication:

[0040] Running light: red, always on after pressing the switch;

[0041] Sending light: red, the LED light flashes quickly when sending a message;

[0042] Receive light: green, the LED light flashes when a message is received, and a byte flashes once;

[0043] 645 receiving light: green, the LED light is always on after receiving the standard 645 message, and it will be off when it is sent next time.

[0044] After the finder is correctly wired and powered on, it will automatically work within the effective working time. The operator judges whether there is a fault on the 485 bus according to the indicator light (or indication status) on the finder and the electric energy meter.

[0045] If the receiving light flashes, it means that there is an electric energy meter under the bus, which may be multi-meter;

[0046] If the communication light on the energy meter terminal is on or the communication sign appears on the screen, it me...

Abstract

The invention belongs to the technical field of fault finding tools of power lines and discloses a 485 line fault finder. The 485 line fault finder includes a finder and a wire hooking wire. An operation lamp, a transmission lamp, a receiving lamp and a 645 receiving lamp are arranged on the finder. The rear face of the finder is provided with a charge jack while the front face of the finder is provided with two detection leads connected through 485 adaptors. The wire hooking wire is provided with a conical wire hooking groove. Two sides of the conical wire hooking groove are provided with a metal sheet and an arc-shaped sheet respectively. The other end of the arc-shaped sheet is provided with a spring in elastic connection. The metal sheet is provided with an indication lamp connected through a lead. The wire hooking clamp is provided with an insulation rod. The detection lead penetrates through the insulation rod so as to connect with the metal sheet in the wire hooking clamp. According to the invention, an alligator wire clip is changed to the wire hooking clamp, and a handheld insulation rod can be hooked on a to-be-detected wire directly, so that technical problems of high risks and detection inconvenience in the prior art are solved effectively.

Description

technical field [0001] The invention belongs to the technical field of power line fault finding tools, and relates to a 485-line fault finder. Background technique [0002] 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. [0003] 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. [0004] 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...
