Abstract

The invention provides a low-voltage switchgear and a box-type substation, relating to the technical field of power distribution cabinets, including a cabinet body and an installation part; the cabinet body is provided with a first installation space for installing a main circuit breaker, and a rear panel There is an installation opening communicating with the first installation space; the installation part is hinged with the cabinet body, and the installation part, the cabinet body and the cabinet door are surrounded to form a second installation space that communicates with the first installation space. In order to allow the operator's arm to extend into the first installation space through the second installation space and touch the installation position of the copper wire bar on the main circuit breaker when turning away from the cabinet door. Compared with the installation method in which two people stand in the transformer compartment at the same time, the movable space of the two operators is larger, which is more convenient for the installation of the copper wire row; and only one operator's arm is required to pass through the installation opening on the back panel , The mounting opening on the rear panel can be made smaller, which improves the protection level of the switchgear.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a low-voltage switch cabinet and a box-type substation. Background technique [0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a kind of substation equipment integrating high-voltage power distribution device, transformer and low-voltage power distribution device. Usually, in order to meet the protection level, the outer box of the box-type substation is separated into three independent compartments by partitions or partition walls. The high-voltage power distribution device, transformer and low-voltage power distribution device are respectively arranged in the three compartments. The high voltage input by the power distribution device is output to the low-voltage power distribution device through the transformation function of the transformer. [0003] The low-voltage power distribution device is mostly inte...
