Abstract

The invention discloses a medium-voltage narrow indoor armor moving open type alternating current metal closed switch cabinet used for KYN28-12. The medium-voltage narrow indoor armor moving open type alternating current metal closed switch cabinet comprises a cabinet body and a packaged metal sheet in front of the cabinet body. The packaged metal sheet comprises a first packaged metal sheet body, a second packaged metal sheet body and a third packaged metal sheet body sequentially from top to bottom, one end of the first packaged metal sheet body, one end of the second packaged metal sheet body and one end of the third packaged metal sheet body are fixed through hinge pieces, and the other end of the first packaged metal sheet body, the other end of the second packaged metal sheet body and the other end of the third packaged metal sheet body are fixed through buckling pieces. The parts of the closed switch cabinet are high in precision, and convenient to fast and accurately assembled, the protection level reaches IP4X, and the using condition of switch equipment is met.

Description

technical field [0001] The invention relates to a high and low voltage electrical switchgear, in particular to a medium-voltage narrow indoor armored removable AC metal-enclosed switchgear. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., and some also have high-voltage chambers and low-voltage chambers. [0003] The whole structure of the traditional switchgear is often produced in the same way, which is inconvenient to disassemble. When one of the electronic control units fails, it needs to be disassembled for maintenance, which is time-consuming and laborious. Moreover, the door of the switch cabinet adopts a bolt-fixed structure, which is inconvenient to switch. Contents of the invention ...
