Abstract

The invention discloses electric system repairing detecting equipment and in particular relates to a power-frequency high-voltage electroscope tester. The power-frequency high-voltage electroscope tester also comprises an adjusting and boosting circuit arranged in a box body; a power switch (2), a reminder lamp (3), an adjusting turntable (5), a voltage meter (6) and a metal clamp (7) are arranged on a face plate of the box body, wherein the power switch is used for controlling the on and the off of the adjusting and boosting circuit, the reminder lamp is formed by a light-emitting tube (Fg), the adjusting turntable is used for controlling the voltage of a self-coupling voltage adjustor (B1), the voltage meter is used for indicating the secondary side output voltage value of a transformer (B2), and the metal clamp is connected with a live wire connecting lead. The power-frequency high-voltage electroscope tester has the following functions that a power-frequency high-voltage electroscope is tested by the tester; the tester accords with the rule of determining the electroscope to be excellent by using a power-frequency high-voltage generator in a newly published safety rule and is capable of exactly detecting out whether the power-frequency high-voltage electroscope is normal or not, simple in structure and capable of finishing test by using 220V electric supply only; in addition, the entire testing process is very safe.

Description

technical field [0001] The invention relates to a power system maintenance and detection equipment, in particular to a power frequency high voltage electroscope tester. Background technique [0002] In the power system, when the power transmission line and electrical equipment are out of power for maintenance, the power test must be done first, and the specific work can only be carried out after confirming that there is no dangerous power supply. The high-voltage electroscope for detection must be pre-tested on the same level of electrified body before use. After confirming that the electroscope is normal, it can be transferred to the power-off body for testing experiments to determine whether there is still dangerous electricity in the power-off body. . [0003] However, in the field, when the front-end line is overhauled or tripped due to a fault, the follow-up circuit has no high voltage for testing, including some closed cables, and there is no exposed point for testing...
