Main technical parameters of YC1-12 series transformer handcart



Main structure and working principle of the product
1. Working principle
The handcart is floor standing. When entering the cabinet, align the wheels with the guide rails on the bottom plate of the cabinet and directly push it into the cabinet. During the pushing process, the left and right bending plates on the handcart lift the valve, and the moving contact is inserted into the stationary contact. When the moving contact is in place, the positioning pin on the handcart automatically inserts into the positioning hole of the cabinet, completing the handcart entering the cabinet. When the handcart needs to be pushed out of the cabinet, first step on the foot pedal, release the positioning, pull out the handcart, and at the same time, the valve on the cabinet is closed, completing the handcart exiting.
