Automatic Safety Device For Busbar Processing Machine

The busbar processing machine is a supporting equipment designed based on advanced foreign products and combined with domestic reality to improve work efficiency and ensure job safety. In order to facilitate further understanding of the busbar processing machine, the following editor will introduce the safety automatic device of the busbar processing machine:

When the short circuit fault occurs in the power distribution system of the bus processing machine, there will be Voltage sag, surge or system asymmetry, which may lead to the interruption of production or other processes, resulting in huge losses. In order to avoid such incidents, the requirements for power supply quality of power enterprises continue to increase, and the power industry is undergoing significant changes as a result.

The insulating material used for the Bus duct of the CNC bus processing machine is the material with a working temperature of 105 ℃. Radiation cross-linked flame retardant winding tape and radiation cross-linked polyhydrocarbon heat shrinkable tube with a working temperature of 140 ℃ or above have been developed. However, the normal working temperature of the insulating material used for the cable is 95 ℃ and 105 ℃, so the overload capacity of the Bus duct is far greater than that of the cable.

The automatic devices of CNC bus processing machines include differential protection for transformers, high-frequency protection for transmission lines, distance protection, zero sequence current protection, etc. Backup protection is a protection that operates when the main protection or circuit breaker of the protected electrical equipment, transmission line fails, such as overcurrent protection for transformers and transmission lines. Automatic safety devices such as transmission line automatic reclosing device, auxiliary power backup power automatic switching device, Electrical substation bus or sectionalized bus backup power automatic switching device, automatic load shedding device according to frequency, electric braking and automatic switching device, etc.
