To improve the service life of the voltage breakdown strength tester, it is necessary to comprehensively manage it from multiple aspects such as daily maintenance, operating standards, environmental management, accessory replacement, and professional maintenance. The specific measures are as follows:

1、 Daily maintenance and cleaning

1. Regularly clean the surface and interior of the equipment

Use a soft dry cloth to wipe the device casing, avoiding the use of corrosive cleaning agents or fabrics containing particles to prevent scratching the surface or damaging electrical components.

Regularly clean the dust and debris inside the equipment, especially key components such as high-voltage generators and electrodes, to prevent poor heat dissipation or electrical short circuits caused by dust accumulation.

2. Check and tighten the connecting components

Regularly check whether the power lines, signal lines, grounding wires, and other connections of the equipment are firmly connected to avoid heating or electric sparks caused by poor contact, which may damage the equipment.

Check whether the electrodes are loose or worn, adjust or replace them in a timely manner to ensure testing accuracy and equipment safety.

2、 Standard operating procedure for voltage breakdown strength tester

1. Strictly follow the operation manual

Before use, carefully read the equipment operation manual to understand the performance parameters, operating steps, and safety precautions of the equipment.

Follow the procedures specified in the manual for startup, testing, and shutdown to avoid equipment damage caused by misoperation.

2. Avoid overloading operation

Do not exceed the maximum test voltage and current range specified by the equipment to prevent internal components from burning out due to overload.

During the testing process, closely observe the operating status of the equipment. If any abnormalities are found (such as odor, abnormal noise, overheating, etc.), the testing should be stopped immediately and the cause should be checked.

3. Preheating and stabilization

Before formal testing, preheat the equipment for a period of time to stabilize the internal temperature, improve testing accuracy and equipment stability.

During the testing process, maintain a stable ambient temperature to avoid affecting equipment performance due to temperature fluctuations.

3、 Environmental management of voltage breakdown strength tester

1. Control environmental temperature and humidity

Store the equipment in a dry, ventilated, and non corrosive gas environment, with a recommended temperature range of 0-40 ℃ and humidity control of 20% -80%.

Avoid exposing equipment to high temperature, high humidity, or low temperature environments to prevent component aging, corrosion, or deformation.

2. Reduce vibration and impact

Place the device on a stable workbench, avoiding frequent movement or vibration, and preventing internal components from loosening or being damaged due to mechanical impact.

When transporting or handling equipment, use specialized packaging boxes and fixing devices to ensure equipment safety.

3. Avoid electromagnetic interference

Keep the equipment away from strong electromagnetic sources (such as large motors, transformers, etc.) to prevent electromagnetic interference from affecting the testing accuracy and stability of the equipment.

Use shielded cables to connect equipment and reduce interference during signal transmission.

4、 Accessory replacement and upgrade

1. Regularly replace vulnerable parts

According to the recommendations in the equipment manual, regularly replace vulnerable parts (such as electrodes, fuses, capacitors, etc.) to prevent equipment failure caused by component aging.

When replacing accessories, use original or compliant accessories to ensure equipment performance and safety.

2. Upgrade software and firmware

Pay attention to software updates and firmware upgrades released by device manufacturers, upgrade device software in a timely manner, fix known vulnerabilities, and improve device performance and stability.

Before upgrading, backup device data to prevent data loss due to upgrade failure.

5、 Professional maintenance and calibration of voltage breakdown strength tester

1. Regular professional maintenance

At least one professional maintenance should be carried out annually, with comprehensive inspection, cleaning, lubrication, and adjustment conducted by the equipment manufacturer or authorized repair organization to ensure that the equipment is in optimal working condition.

Professional maintenance includes checking the performance of key components such as high-voltage generators, electrode systems, and control systems, replacing aging components, and adjusting equipment parameters.

2. Regularly calibrate equipment

Regularly calibrate the testing parameters of the equipment (such as voltage, current, time, etc.) according to the frequency of use and accuracy requirements, to ensure the accuracy and reliability of the test results.

Calibration should be carried out by qualified metrology institutions and a calibration certificate should be issued as proof of equipment performance.
