Novel lightning protection box

Abstract

The invention relates to a novel lightning protection box, and belongs to an AC / DC power supply inductive thunder prevention lightning protection box. The novel lightning protection box mainly comprises an input terminal, an output terminal, an automatic switch, a first-stage protection zinc oxide module and inductor, a second-stage protection zinc oxide module and inductor, a third-stage protection transient suppression diode and detecting module, an information collecting module and an intelligent module, and further comprises a normal and accident display lamp and an additional resistor. By means of the novel lightning protection box, the problem of the power (energy) and respond speed of a protection device is solved; meanwhile, the detecting module, the information collecting module and the intelligent module are effectively matched, and therefore a user can obtain related information of lightning stroke and related information of a lightning protection element in time, grasp the running state of a system and eliminate the potential safety hazards.

Description

technical field [0001] The invention belongs to an AC and DC power supply induction lightning protection box. Background technique [0002] Lightning is a special weather phenomenon caused by the discharge of charged clouds in the air. Lightning threatens the safe and stable operation of equipment in various fields such as construction, railways, civil aviation, communications, industrial control, and military. Installing protective devices on metal lines such as power lines, signal lines, and control lines connected to equipment is one of the important measures for lightning protection. However, although lightning protection boxes currently on the market are installed on metal lines such as power lines, signal lines, and control lines connected to the equipment, the situation that the equipment is damaged occurs from time to time, and sometimes even the lightning protection box fails. The equipment that it protects is damaged when it is damaged. The reason is that lightni...

Problems solved by technology

Nowadays, the response time of zinc oxide lightning protection boxes on the market usually lags behind the response time of the equipment to be protected. After a lightning strike occurs, the lightning protection box is not damaged, but the protected equipment is damaged from time to time. , the occurrence of this situation has brought immeasurable losses

At the same time, the unknowability of the status of lightning protection devices has brought difficulties to the protection work and left hidden dangers for safety issues.

[0003] Regarding the patent document "Serial multi-level integrated power surge arrester" (authorized announcement number: CN1212686C), although the problem of the power and response speed of the protective device has been solved, the state of the lightning protection device and the protective circuit is not known.

And the relevant situation on the scene can only be understood after arriving at the scene, and the information obtained is also limited, which brings trouble to the staff, and there are also hidden dangers in safety
