Description
Technical Field
The invention relates to the technical field of lightning arrester tests, in particular to a zinc oxide lightning arrester multiple lightning stroke simulation test device and a test method.
Background
In real life, when lightning strikes an overhead power line or the earth near the line, overvoltages are generated on the power line, which are transmitted in the form of electromagnetic waves along the line to the transformer substation at the line terminal, endangering the equipment with weak insulation in the transformer substation, and an overvoltage protection device must be installed to protect the electrical equipment. The lightning arrester is used as important lightning protection equipment and plays a role in absorbing and releasing lightning impulse energy. At present, the high-voltage electrical equipment of the transformer substation adopts a metal oxide arrester as key equipment for lightning overvoltage protection and protective equipment for operating overvoltage, the metal oxide arrester is generally a zinc oxide arrester, and the zinc oxide arrester achieves a safety lightning protection function by utilizing good nonlinear volt-ampere characteristics of zinc oxide resistance sheets and is widely applied to overvoltage protection of the high-voltage electrical equipment of the transformer substation. The zinc oxide arrester is connected in parallel between the high-voltage end of the high-voltage equipment of the transformer substation and the ground, the arrester does not act when the high-voltage equipment of the transformer substation operates under normal operating voltage, the ground can be regarded as an open circuit, once high voltage exceeding the normal operating voltage occurs and the protected equipment is endangered to be insulated, the zinc oxide arrester can immediately act to guide high-voltage impact current to the ground to limit the voltage amplitude, the high-voltage equipment of the transformer substation is protected, and the zinc oxide arrester can quickly recover to be in an original state after the overvoltage disappears so that the high-voltage equipment of the transformer substation normally operates.
Before the lightning arrester is delivered from a factory or put into operation on site, the lightning arrester is required to be tested in a whole through flow mode, so that the use stability and safety of the lightning arrester are ensured. In the prior art, in order to simulate a waveform circuit formed by multiple lightning strokes, multiple lightning stroke simulation tests are carried out on the lightning arrester simultaneously or in batches, so that the voltage withstand performance of the lightning arrester is ensured to be good. When the lightning arrester is in through-flow detection, because whether the lightning arrester is intact or the performance is in an optimal state is unknown, the lightning arrester needs to be manually and repeatedly carried, assembled and wired, and when a large number of lightning arrester detection tests are carried out, the operation and use efficiency is low, and the loop contact resistance is changed when wiring each time, so that the deviation of the test is also caused. Therefore, the development of the automatic zinc oxide lightning arrester multiple lightning stroke simulation test device has practical application value for improving test precision and reducing operation difficulty of test personnel.
