LJC-20kv voltage breakdown tester

1、 Compliant with standards and applicable materials

satisfyGB1408-2006Test method for electrical strength of insulating materials,GB/T1695-2005Test for power frequency voltage breakdown strength and voltage resistance strength of vulcanized rubberGB/T3333Test method for power frequency voltage breakdown of cable paperHG/T 3330Determination method for breakdown strength of insulating paint filmGB12656Test method for power frequency voltage breakdown of capacitor paperASTM D149Standard requirements.Mainly suitable for testing the breakdown strength and withstand time of solid insulation materials such as plastics, films, resins, mica, ceramics, glass, insulation paints, etc. under power frequency voltage or DC voltage.

2、 Software program control function:

1During the testing process of this device, the test curve can be dynamically drawn, and the test curve can be overlaid and compared with multiple colors.

2Can edit and modify experimental data, flexible and applicable;

3The experimental conditions and test results can be automatically stored;

4The format of the test report is flexible and adaptable to meet the different requirements of different users.5The validity of curve data in a set of experiments can be manually selected.

6The experimental result data can be importedEXECL.

7The software equipment personnel management function allows test personnel to set their own test items and parameters, and after setting their own test content, others cannot enter.

Employee management function, where test personnel can set their own test items and parameters, and others cannot enter after setting their own test content.

3、 Equipment security protection function:

1The equipment should be equipped with a separate protective grounding wire, mainly to reduce the strong electromagnetic interference generated by the sample breakdown on the surrounding area. It can also prevent the computer from losing control.

2DC test discharge alarm function:When the device completes the DC test,When the test door is opened, the equipment will automatically sound an alarm,The alarm will automatically cancel after the discharge device on the equipment is used to discharge.(Note: Failure to discharge electricity after DC testing may pose a risk to personal safety,

Cannot directly take the electrode,Remind users to discharge to avoid personal injury).

3Add a manual discharge device for testing, which is integrated with the host. In the event of a sudden power outage during the DC test, a manual discharge rod can be used for discharge to ensure the personal safety of the testing personnel.

4The circuit of the test equipment is equipped with multiple protection measures, mainly including overcurrent protection, voltage loss protection, leakage protection, short circuit protection, DC test discharge protection, etc.
