The difference between dual power automatic transfer switch and isolation switch

1. The amount of current disconnected by the two is different

Since the isolating switch does not have a magnetic blowing device, it is only suitable to disconnect the unloaded current, but cannot disconnect the load current and short-circuit capacity. Therefore, the isolating switch household appliances can only be safe when the power circuit is safely disconnected. The operation is carried out carefully, and the operation with load is careful and meticulous, so as to prevent safety production accidents.

Due to the magnetic blowing device, the dual power automatic transfer switch can disconnect the load current and its rated load current, but the same can not disconnect the short-circuit capacity.

2. The dual power automatic switch has a magnetic blowing device, while the isolation switch does not have such a device

So what’s the difference if you have this magnetic blowing device? To put it bluntly, the magnetic blowing equipment is to better assist in the breaking and closing of electrical switches, and can also reasonably limit the electric isolation to help the electric isolation be extinguished. There is such a magnetic blowing device, which is safer for electrical switches. Therefore, most of the electrical switches are all equipped with magnetic blowing equipment. It is an electrical switch for home use.

3. The functions of the dual power automatic transfer switch and the isolation switch are different

Because the isolation switch has no magnetic blowing equipment, it is generally used in the part of the high-voltage power supply circuit equipment that must be energized and the part that must be powered off to carry out an isolation function, so as to ensure the maintenance of the high-voltage power supply circuit by the staff. and inspections to ensure the safety of staff.

The dual power automatic transfer switch is used in mobile high-voltage equipment, which can disconnect the common fault current in the high-voltage equipment and its rated current, so the functions of the two are different, but the two are completely It is used in high pressure equipment. Naturally, in low-voltage electrical, there are also related isolating switches and dual-power automatic switching switches.
