What are the components of the phase comparison impedance relay?

The phase comparison impedance relay consists of a moving contact, a stationary contact, a square rotating shaft, a handle, a positioning mechanism and a shell. Its moving and static contacts are stacked in several layers of insulating pads, forming a double-breakpoint bridge structure. The movable contact piece is sleeved on an insulated square shaft with a handle, and the square shaft rotates with the handle. Therefore, the position of each layer of moving contact changes with the rotation of the square shaft, thus breaking and contacting with the static contact. The top cover of the combination switch consists of a cam, a spring and a handle. This mechanism uses spring to store energy, so that the switch can be closed and opened quickly. The opening and closing speed of the combined switch has nothing to do with the speed of the handle, which is beneficial to arc extinguishing.
