Description

Device for magnetic suction voltage measurement

technical field

The utility model relates to the field of equipment for measuring electric power parameters, in particular to a magnetic suction type voltage measuring device.

Background technique

During the voltage measurement work, the staff holds the alligator clip in contact with the voltage point to be measured. When the measurement time is long, the stability of the hand-held alligator clip will deteriorate, resulting in a decrease in the contact stability between the alligator clip and the point to be measured, which will affect the measurement. Result accuracy. Faced with this problem, our company has made a patent application with the patent number "201120332250.7". Although the technical solution disclosed in this patent can greatly improve the stability of the contact between the measuring end and the point to be measured, In order to ensure the effective contact between the measuring end and the point to be measured, it is still necessary for the staff to manually control the gripper, so after a long time, not only the staff will feel fatigued, but also indirectly affect the stability and stability of the measurement. degree of accuracy.

Utility model content

The technical task of the utility model is to provide a magnetic suction type voltage measuring device for the above-mentioned technical deficiencies.

The technical solution adopted by the utility model to solve the technical problem is: a magnetic suction type voltage measuring device, including a wire and two circular frustum-shaped insulating shells connected by threads, and the front end of the wire passes through the two insulating shells and is fixedly connected with a front A metal joint, the end of the front metal joint close to the wire is covered with a ring-shaped magnet, the ring-shaped magnet is fixedly connected to the insulating shell close to the front metal joint, the rear end of the wire is fixedly connected to the rear metal joint, and The rear metal joint is sheathed with an insulating outer cover.

A fuse is provided on the wire.

The beneficial effects that the utility model can bring are:

1. The measurement work becomes easier and faster;

Second, the accuracy and stability of the measurement results are better.

Fig. 1, the overall structure schematic diagram of the utility model.

Detailed ways

As shown in Figure 1, the magnetic suction type voltage measurement device disclosed by the utility model includes a wire 1 and two circular frustum-shaped insulating shells 2 connected by threads, and the front end of the wire 1 passes through the two insulating shells 2 and is fixed. A front metal joint 3 for contacting with the point to be measured is connected.

One end of the front metal joint 3 close to the wire 1 is covered with a circular magnet 4, which is fixedly connected with the insulating shell 2 close to the front metal joint 3, and the use of the magnet 4 can ensure that the front metal joint 3 The tightness and continuity of contact with the point to be measured.

The rear end of the wire 1 is fixedly connected with a rear metal connector 5 for connecting to an alligator clip, and the rear metal connector 5 is covered with an insulating cover 6 .

In addition, the wire 1 is provided with a fuse 7 to ensure safe operation of the circuit.

To sum up, the utility model avoids the work fatigue caused by manually supporting the holder for a long time under the technical solutions disclosed in the existing patents, as well as the influence on the stability and accuracy of the measurement results. Make voltage measurement work easier, faster, more stable and more accurate.
