Abstract
The utility model discloses an apparatus for zinc oxide lightning arrester energized testing, and solves the problems that in present, for testing personnel, the labor intensity is high and the safety factor is low. A lightning arrester pedestal (2) is arranged on a cement pillar (3). The lightning arrester pedestal (2) is provided with a zinc oxide lightning arrester (1). The zinc oxide lightning arrester (1) is connected to a bus (13). The lightning arrester pedestal (2) is connected to a grounding bar (4) through an ammeter (12). A current signal end (8) of a zinc oxide lightning arrester measuring instrument (7) is connected to the two ends of the ammeter (12). The top end of a telescoping insulator spindle (5) is provided with a connecting rod (10). One end of the connecting rod (10) is connected with a magnet piece (11). The other end of the connecting rod (10) is connected with an inductive board (6). The inductive board (6) is connected to a voltage signal end (9) of the zinc oxide lightning arrester measuring instrument (7). The safety risks for the testing personnel are reduced.
Description
Technical field
The utility model relates to Zinc-Oxide Arrester live testing device in a kind of electric system, is used for total current and current in resistance property under the test Zinc-Oxide Arrester working voltage.
Background technology
In the electric system, Zinc-Oxide Arrester is a kind of very important overvoltage protection.Along with the lightning arrester growth of working time, its inner valve sheet resistance defective and internal fault such as can occur wearing out, make moist.For the ease of finding the Zinc-Oxide Arrester internal fault, utilizing lightning arrester live testing instrument measurement lightning arrester total current and current in resistance property under working voltage is a kind of very effective method.At present, lightning arrester live testing method mainly is divided into two kinds, i.e. PT secondary method and tablet method.Wherein, PT secondary method need be gathered its secondary voltage signal in the voltage transformer (VT) operation, for the equipment operation has brought risk, and the tablet method only need be placed on tablet near the lightning arrester base, with the voltage of sensing as the reference signal, so tablet method application safety, convenience are used also relatively extensively.But because lightning arrester base overhead has higher distance, therefore tablet to be placed near the lightning arrester base, sometimes need the tester to step down on ladder or the stool, so not only increased labour intensity, but also reduced people and the distance of charging equipment on every side, threaten tester's safety.
Summary of the invention
The utility model provides a kind of Zinc-Oxide Arrester live testing device, has solved existing the tester big and low problem of safety coefficient of labour intensity at work.
The utility model is to solve above technical matters by the following technical programs:
A kind of Zinc-Oxide Arrester live testing device, comprise the cement pillar, the cement pillar is provided with lightning arrester base, lightning arrester base is provided with Zinc-Oxide Arrester, Zinc-Oxide Arrester is connected on the bus, the Zinc-Oxide Arrester base is connected with ground connection row by reometer, the current signal end of Zinc-Oxide Arrester measuring instrument links to each other with the two ends of reometer, top at flexible insulating bar is provided with connecting link, one end of connecting link is connected with magnet piece, the other end of connecting link is connected with tablet, and tablet is connected with the voltage signal end of Zinc-Oxide Arrester measuring instrument.
The top of flexible insulating bar and connecting link are provided with insulating sheath by being threaded togather in the bottom of expansion link.
The utility model ground can easily be placed in lightning arrester live testing instrument tablet on the lightning arrester base or base under channel-section steel on, reduced labour intensity, reduced tester's potential safety hazard.
Description of drawings
Fig. 1 is structural representation of the present utility model.
