The vending machine accessories are connected to the longitudinal extension of the bridge, and the crossbar is used when the bridge is hoisted. Lifting brackets are used in this case. The lifting bracket is composed of a boom and a crossbar, the shape is U-shaped, the upper end of the boom is fixed on the roof plate and other supports, and the lower end is installed with a crossbar, which is used to support the weight of the bridge.

The crossbar refers to a component of the bridge hanger; Staggered wiring, indicating that the high voltage is D (delta) connection. If this transformer does not have this staggered wiring, but the upper part is still the socket, and the lower X, Y, Z terminals are connected together, then the high voltage is Y (star) connection. This is the mold of the manufacturer in order to unify the high voltage coil.

In other words, regardless of whether the high-voltage coil is connected to D or Y, the same outlet (terminal) is arranged. Adjust its control switch directly. The second is non-excitation voltage regulation, dry-type transformer non-excitation voltage regulation is through the adjustment of the transformer itself, the layout of the connecting piece is also two, there are two upper and lower rows, three contacts above, three contacts below, and the other is arranged left and right, three on the left and right.
