1. The test equipment (resonant reactor, voltage divider, excitation transformer, etc.) should be placed as close as possible to the tested cable head to reduce the length of the test grounding wire, that is, to reduce the inductance of the grounding wire.
2. приемете специално проектирана група за заземяване на заземяване на една точка . Специално внимание трябва да се обърне за поддържане на тестовия заземен проводник възможно най -кратко и не е произволно разширяване на дължината на заземяващия проводник .
3.During the experiment, the operator should not touch the metal casing of the control box except for the tuning and voltage regulating insulation knobs, otherwise there may be a slight stinging sensation when it is pierced or discharged on the high-voltage side. When conditions permit, it is recommended that operators work standing on rubber insulation pads.
4. The test transformer has three terminals: 800V, 1000V, and 1500V. When the required high voltage of the system is less than 15kV, the 800V terminal is selected. When the required high voltage of the system is greater than 15kV and less than 60kV, the 1000V terminal is selected. When the required high Напрежението на системата е по -голямо от 60kV, 1500V терминалът е избран .
Трансформатор, GIS система, SF6 превключвател CT/PT, изолатори, шини, кабели, ръкави и друго капацитивно оборудване са най -често срещаните електрически устройства в подстанции . According to the requirements of the voltage withstand test regulations for primary electrical equipment in substations of 220V and below, the corresponding AC/DC voltage withstand test equipment must meet both high voltage and low current test conditions, as well as low voltage and high current test conditions. It is required to have a wide range of applicability and adopt the principle of series resonance. The main equipment consists of a variable frequency power supply control box (console), an excitation transformer, a reactor, and a capacitive voltage divider. The DC voltage withstand test can be completed by connecting a rectifier silicon stack and a microampere meter to the capacitive voltage divider. Due to its excellent filtering characteristics after resonance, the DC voltage produced by the system is superior to the DC voltage rectified by ordinary test transformers. It is an ideal high-voltage testing equipment for local, municipal, and county-level high-voltage testing departments, as well as power installation, repair, and testing engineering units.
