Closed busbars must meet relevant regulations when designing and manufacturing them before they can be used out of the factory. So what kind of regulations need to be met when designing a closed busbar? What conditions must its various components meet?
First, the closed type can have the characteristics of voltage resistance. Generally, when designing the busbar, it is required to be able to withstand 3000V50Hz AC power within one minute, and no breakdown or flashover occurs during this period. This is considered qualified.
Second, the connector contact. When designing the connector of the bus duct, double-sided connection technology must be used, so that the total cross-sectional area of its conductor can be appropriately larger, which can enhance its horizontal strength. The current carrying capacity of the cross-sectional area.
Third, when designing the plug interface, you need to pay attention to the fact that its conductor parts need to be silver-plated, so as to ensure that its plug box connection has low impedance characteristics and will not change due to temperature rise.
Fourth, the closed busbar needs interlocking protection to prevent the plug-in box door from being suddenly opened when power is on.It is important to know that the bus duct plug-in box cannot be closed unless it is securely connected to the plug-in box.
Fifth, the busbar must also have a plug-in box to protect against electric shock. It is charged inside. Therefore, in order to avoid the risk of electric shock to the human body during installation, it is required to be equipped with a transparent protective partition to ensure that people safety.
