Description

Technical Field

[0001] The invention belongs to the technical field of insulation testing, and in particular relates to an electrical insulation testing device and a use method thereof. Background Art

[0002] Electrical equipment usually uses non-conductive insulating fiber products, mica, insulating oil, asphalt, glass, ceramics, polymer materials, etc. as insulating materials, but all insulating materials will have physical properties such as polarization, conductivity, loss, and breakdown under the action of external electric fields, thus showing conductivity. In other words, the insulation of insulating materials is relative. The insulation usually mentioned is not complete electrical isolation, but the situation where the conductor is limited to the allowable value. The concept of insulation resistance is introduced to measure the limiting ability of insulating materials to conduction. The basic principle of the insulation resistance meter test is to add the test voltage between the independent circuits to be tested and then detect the leakage current of the circuit to obtain the insulation resistance value. There are many specific measurement methods for insulation resistance, each with its own characteristics. The more typical ones are series method, parallel method, voltage comparison method, capacitor charging method and bridge method. The resistance value of insulation resistance is affected by many factors. For example, increased temperature, increased humidity, and poor cleanliness will reduce the insulation resistance. In addition, insulation resistance is divided into benign insulation resistance and defective insulation resistance. The so-called benign insulation resistance refers to the insulation resistance whose resistance value does not change significantly with the change of the test voltage; while the defective insulation resistance will react with the change of the test voltage. The insulation resistance test is a routine test of electrical equipment. It is one of the methods used to check the insulation defects of electrical equipment based on national measurement standards. The measurement of cable insulation resistance is to check whether the cable insulation is damp, dirty or has local defects. If the cable is damp or has local defects, its insulation resistance will be significantly reduced. At the same time, before testing the electrical insulation resistance, the power supply of the device under test must be disconnected from all aspects and the device under test must be discharged to the ground. The measurement personnel must maintain a sufficient safe distance from the live parts. The working environment of electrical equipment and facilities is very poor, and they often deal with water and mud. Due to untimely maintenance, damage and aging, the insulation performance of electrical equipment and facilities has decreased. On-site electricians cannot regularly perform insulation resistance tests on these electrical equipment and facilities.
