Description

Technical Field

[0001] This utility model relates to the field of lightning protection device testing technology, and in particular to a testing device for building lightning protection devices. Background Technology

[0002] In existing technology, lightning protection devices consist of three parts: an air terminal, a down conductor, and a grounding electrode. Their function is to prevent direct lightning strikes or to conduct lightning current into the ground, ensuring the safety of people and buildings. Lightning protection devices for buildings are generally divided into two categories: external lightning protection devices and internal lightning protection devices. External lightning protection devices consist of an air terminal, a down conductor, and a grounding electrode; this is the traditional lightning protection device. An equipotential bonding tester can measure the voltage difference between different points in an electrical system to ensure that the voltages at these points are at the same level, preventing electric shock, equipment damage, or other safety problems. It is a commonly used testing device for lightning protection devices.

[0003] A search revealed that Chinese patent application number 202323505185.5 discloses an equipotential testing instrument, comprising a testing instrument body and a protective cleaning mechanism. The protective cleaning mechanism is provided on the outer side of the testing instrument body. The protective cleaning mechanism includes a fixing component, a protective component, a sliding component, a cleaning component, a flow guiding component, and a blowing component. The fixing component is provided on the outer side of the testing instrument body, the protective component is provided at the upper end of the fixing component, and the sliding component is provided on the inner side of the protective component.

[0004] The aforementioned patent has the following shortcomings: Most existing equipotential testing instruments have a box-type flip-top structure, which can provide comprehensive protection for the display screen and other structures when not in use. However, when in use, the wiring sockets and display screen pockets are easily affected by the external environment, especially in windy conditions, where dust in the air can easily invade the wiring sockets, affecting the use of the overall device.
