Description

Electrostatic field tester

technical field

The utility model relates to the technical field of testers, in particular to an electrostatic field tester.

Background technique

Due to the friction, extrusion, induction, etc. between the objects, the surface area of the objects has charges of different natures. When these charge circles reach a certain level, electrostatic adsorption and discharge phenomena will occur. The accumulation and discharge of static charges will have a great impact and damage on industrial production. Therefore, detection equipment is required to detect the electric fields of these electrostatic charges.

Existing electrostatic detection devices are generally installed directly on equipment, and only perform electrostatic detection operations on specific equipment.

Therefore, based on the defects of the above-mentioned existing electrostatic field detection equipment, it is necessary to improve the existing electrostatic field detection equipment.

Utility model content

The purpose of the utility model is to provide an electrostatic field tester for the deficiencies of the prior art, which solves the existing defects of the existing electrostatic field testing equipment: inconvenient movement and inconvenient detection.

In order to achieve the above object, the utility model is achieved through the following technical solutions: the electrostatic field tester includes a main body, a corona discharge device, a probe and a detection system are provided in the main body, and buttons and a display screen are provided on the surface of the main body.

The side of the main body has a ground wire socket.

The bottom of the main body is inserted with a movable ion balance board, and the side of the main body has buckles, and the buckles are movably engaged with the ion balance board.

The beneficial effect of the utility model is that: using a given high-voltage electric field, the tested sample is regularly discharged to induce static electricity in the sample, so as to detect the size of the static electricity, the half-life of the static voltage, and the residual amount of static electricity to determine the value of the tested sample. Electrostatic performance, easy to hold and move, very convenient to use.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

See Fig. 1, the electrostatic field tester of the present utility model comprises: main body 11, has corona discharge device, probe and detection system in main body 11, and the surface of main body 11 has button 12, display screen 13, and the side of main body 11 has ground wire plug hole 14.

A movable ion balance plate 16 is inserted at the bottom of the main body 11 , and a buckle 15 is provided on the side of the main body 11 , and the buckle 15 is movably engaged with the ion balance plate 16 .

The utility model uses a given high-voltage electric field to regularly discharge the tested sample to induce static electricity in the sample, thereby detecting the magnitude of the static electricity, the half-life of the static voltage, and the residual amount of static electricity to determine the electrostatic performance of the tested sample.

When measuring static electricity, press and hold the buckle 15, take out the ion balance board 16 for measurement; when measuring some residual voltage, insert the ion balance board 16 to reset.

Certainly, the embodiment described above is only a preferred example of the utility model, and does not limit the scope of implementation of the utility model, so all equivalent changes made according to the structure, features and principles described in the utility model patent scope Or modification, all should be included in the utility model patent scope.
