Description

Technical Field

[0001] The utility model belongs to the technical field of lightning arrester testing devices, and in particular relates to a distribution network lightning arrester testing tool. Background Art

[0002] Lightning arresters are used to protect the lines and electrical equipment in the distribution network system from the hazards of high transient overvoltage, operating overvoltage, and power frequency transient overvoltage during lightning strikes, and to limit the follow-up time, and often limit the follow-up value. Lightning arresters are sometimes also called overvoltage protectors or overvoltage limiters. Lightning arresters are connected between the cable and the ground, usually in parallel with the protected equipment, and can effectively protect electrical equipment. When the electrical equipment is operating at normal operating voltage, the lightning arrester will not take effect and is considered to be a short circuit to the ground; when high voltage appears and endangers the insulation of the protected equipment, the lightning arrester will immediately act to direct the high voltage impact current to the ground, thereby limiting the voltage amplitude and protecting the power lines and equipment; when the overvoltage disappears, the lightning arrester quickly returns to its original state, allowing the electrical equipment to work normally.

[0003] During the production process, distribution network arresters need to undergo high voltage testing to check whether their quality is up to standard. The existing distribution network arrester test fixture has a relatively simple structure and can only test arresters of a single size. At the same time, the existing test fixture cannot meet the testing requirements for arresters with gaps. It can be seen that the application scope of the existing test fixture is very limited and cannot meet the needs of production enterprises. Utility Model Content
