The low-voltage electrical disconnect switch, that is, the electrical disconnect switch with rated voltage less than 1000VAC, is often referred to as the electrical disconnect switch. It is a kind of electrical appliance used in low-voltage switchgear. Its working principle and structure are relatively simple, but it is reliable due to its large amount of use. The high requirements are high, and the impact on the design, establishment and safe operation of substations and power plants is large. The main feature of the electrical disconnect switch is that it has no arc extinguishing capability, and can only divide and close the circuit without load current.
