Dec 07, 2016

Hand cart / drawer: the hand cart and the drawer are respectively a part of a high voltage switch cabinet and a low voltage switch cabinet, respectively installation of high voltage circuit breakers and low-voltage circuit breakers and relays and other components, thus divide into hand cart type switch cabinet (high voltage) and drawer type switch cabinet (low voltage), the function basically the same as the fixed switch cabinet. The main difference is convenient for maintenance and repair (handcart and drawers can be operated by mechanical mechanism to push and pull out by handle). The handcart and the drawer generally have three position statuses: working (normal operation), test (put into operation test and site test) and exit (maintenance and repair).
