The first brand of copper braided wire [Yajie, Gu Xiaoxia, 3] is customer-centric, adhering to the corporate spirit of self-improvement and pursuit of excellence, and insisting on efficient, pragmatic, rigorous and dedicated work style and standardized service work methods, aiming to provide customers with high-quality products and services
The main transformer of the six-thousand-volt workshop substation for copper braided wires is usually equipped with time-limited overcurrent protection. Generally, a current protection device will be installed to protect it normally. If the overcurrent protection action time is greater than..., a current quick-break protection should also be installed.
The current quick-breaking protection copper braided wire is matched with the gas protection copper braided wire, and the gas protection capacity is . Oil-immersed transformers and above should be equipped with gas protection as the main protection against internal faults and oil level drops in the transformer tank. The copper braided wire can quickly remove various faults on the high-voltage side of the transformer and within it, and is the main protection of the transformer. Overcurrent protection is a relay protection device installed to prevent overcurrent caused by external short circuit of the transformer and as a backup protection for the main protection of the transformer.
In fact, copper strips can also play the same role. When the current passes through the conductor, the current in the center of the conductor is zero, which means that the current is transmitted through the surface of the conductor. In soft connections, the large surface area of the copper strips has relatively large impedance. It is relatively low, so copper tape should be used as much as possible when connecting power.
When it comes to non-powered connections, because the impedance of braided wires is relatively large and the load-bearing capacity is relatively weak, try to choose non-powered connections. And for cost considerations, most generally choose copper tape instead of braided wires. Braided wire is only used in certain environments and work requirements.
The temperature protection is used as a protection device to protect the transformer oil temperature from rising and the cooling system from malfunctioning. Single-phase ground fault protection consists of a zero-sequence current transformer and a current relay connected to it. As a protection against single-phase ground fault on the high voltage side of the transformer.
Copper soft connections for mining explosion-proof electrical appliances_Suzhou environmental protection mining explosion-proof electrical appliances copper soft connections_Tangshan environmental protection mining explosion-proof electrical appliances copper soft connections are generally single hard copper wires and multiple strands are soft copper wires. Soft and hard are relative. People call copper wires that are harder and not easy to bend when pinched by hand, and conversely, copper wires that are easy to change shape are called soft
