[0002] The contactless quick-connect device for power grid line fault detection is a device used for power grid maintenance and fault detection. Its key feature is the ability to quickly and effectively detect and diagnose faults without direct contact with the power lines.

[0023] See also Figures 1 to 4 In an embodiment of the utility model, a contactless quick connection device for detecting power grid line faults includes: a clamp ammeter 1, a conductive member 2 is connected to the clamp ammeter 1, a traction member 3 is connected to the conductive member 2, and the bottom of the clamp ammeter 1 is threadedly connected to one end of a telescopic member 4.

[0024] In this embodiment, first, when the circuit is overhauled, the two handles 101 on the clamp-on ammeter 1 are pinched by the operator, so that the jaws of the clamp-on ammeter 1 are opened, so that the jaws surround the circuit, and the current and voltage of the circuit are detected without contact, which can realize convenient detection effect, and when the operator is not convenient to reach a long distance, and the circuit is soft and not convenient to use the existing clamp-on ammeter for clamping detection, the conductor 2 is installed on the back of the clamp-on ammeter 1, the first conducting column 201 is screwed into the first connecting hole 102, the second conducting column 202 is screwed into the second connecting hole 103, the rotating ring 302 is sleeved on the first conducting column 201 at this time, the bifurcated part of the traction rope 301 is conducted on the second conducting column 202, and then the threaded head 402 is screwed into the connecting seat 105 part, and the stretching and contracting of the stretching rod 401 is adjusted, and the grip handle 403 part is gripped, so that the clamp-on ammeter 1 is sent to a long distance or a place where the operator is not convenient to reach to detect the current and voltage of the circuit, and when the pull rod 303 is pulled, the traction rope 301 is pulled, and the Y-shaped bifurcated end of the traction rope 301 is conducted on the second conducting column 202, and the rotating ring 302 is rotated on the first conducting column 201.

[0025] When the traction rope 301 is pulled, the distance between the two ends of the Y-shaped bifurcation is reduced, so that the distance between the two first conducting columns 201 is reduced, and the two handles 101 are rotated and folded, so that the jaws of the clamp-on ammeter 1 are opened, and the clamp-on ammeter 1 can be sent to a long distance to detect the circuit, and the jaws can normally surround the circuit for detection, first, the non-contact rapid connection detection effect of the circuit, the overall length of the traction rope 301 and the stretching length of the stretching rod 401 are the same, which can ensure that the traction rope 301 can be normally pulled and used after the stretching rod 401 is adjusted, and the use effect is ensured, and the clamp-on ammeter 1 is an existing public technical means, which will not be described in detail here.

[0026] As a further scheme of the utility model, the first connecting hole 102 is formed in the handle 101 symmetrically arranged on both sides of the clamp-on ammeter 1, the second connecting hole 103 is symmetrically formed in the back of the clamp-on ammeter 1, the arc-shaped sliding groove 104 is symmetrically formed in the back of the clamp-on ammeter 1, and the connecting seat 105 is arranged at the center position of the bottom of the clamp-on ammeter 1.

[0027] In this embodiment, the handles 101 on both sides of the clamp ammeter 1 are used for pinching and adjusting so that the jaws of the clamp ammeter 1 can be opened and adjusted. The first connecting hole 102 and the second connecting hole 103 are used for threaded connection with the first conductive column 201 and the second conductive column 202 respectively. When the traction member 3 is not in use, the conductive member 2 can be disassembled to separate the clamp ammeter 1 from the traction member 3, thereby achieving the effect of convenient storage and use.

[0028] As a further solution of the present invention, the conductive member 2 includes a first conductive column 201 and a second conductive column 202. The first conductive column 201 and the second conductive column 202 are symmetrically arranged. The two first conductive columns 201 are respectively threadedly connected to the two first connecting holes 102, and the two second conductive columns 202 are respectively threadedly connected to the second connecting holes 103. The first conductive column 201 is slidably connected to the sliding groove 104.

[0029] In this embodiment, the first conductive column 201 and the second conductive column 202 are used to be threadedly connected to the first connecting hole 102 and the second connecting hole 103 on the back of the clamp ammeter 1, so that the traction member 3 can adjust and control the opening and closing of the jaws of the clamp ammeter 1. The first conductive column 201 slides in the sliding groove 104. When the distance between the two handles 101 is reduced and adjusted, the first conductive column 201 can slide in the sliding groove 104 to meet the requirements of the movement path.

The two rotating rings 302 are respectively rotatably connected to the two first conduction columns 201, and the traction ropes 301 at both ends of the fork are conducted on the second conduction column 202.

[0031] In this embodiment, the traction rope 301 is rotatably connected to the first conductive column 201. When the traction rope 301 is pulled toward one end of the pull rod 303, the traction rope 301 at the Y-shaped fork will be conducted on the second conductive column 202, thereby reducing the distance between the traction ropes 301 at both ends of the Y-shaped fork. The rotating ring 302 will rotate on the first conductive column 201. After the distance between the two first conductive columns 201 is reduced, the distance between the two handles 101 can be reduced, thereby opening the jaws of the clamp ammeter 1, which is convenient for enclosing and contactless detection of the circuit.
