The Function Of Composite Surge Protector - These 3 Points Need To Be Known

So far, the current development trend of the world is economic integration. Under this situation, my country's economy is also developing rapidly, and its power system and electrical engineering are gradually becoming integrated in the direction of industry and automation. So in the field of our lightning protection warning system, can the composite surge protector effectively protect against lightning? So what is the actual role of the composite surge protector, and can it achieve the expected effect? ​​Let's discuss it together.

1. What is a composite surge protective device?

To know the role of the composite surge protector, we must first understand what a composite surge protector is, right? Other types of surge protectors include voltage switching SPD and voltage limiting SPD. Here we will first introduce the composite surge protector!

Composite SPD combination SPD is also called a composite integrated full-protection surge protector. The appearance design adopts a box-type structure. It is an SPD composed of voltage switching components and voltage limiting components. Its characteristics can be expressed as voltage switching type, voltage limiting type or both according to the characteristics of the applied voltage. It can make full use of the advantages of different components and play its role. There are a series of other advantages below ↓, which represent the high performance and high protection of the composite surge protector.

2. Let's take a formal look at the role of the composite surge protection device?

The role of the composite surge protector is to limit transient overvoltage and discharge surge current. These overvoltages may come from the occurrence of natural lightning, or from our own activities, such as the start-up of large equipment, etc. Accidents such as the damage of electrical equipment may occur at any time. Adding a surge protector to the equipment can basically prevent the overvoltage inside the building from harming our other electrical equipment.

Its connection method is generally connected in parallel to the main circuit. It usually has a high impedance property. When TOV appears in the circuit, it will conduct and discharge surge current. At this time, it is in the conduction mode and can be regarded as a directly grounded wire, which can discharge the surge current in the main circuit to the ground wire. The surge protector can be compared to the "guardian god" of products in the electrical system or communication system, protecting the safety of circuits and equipment during lightning strikes and overvoltage.
