Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] see Figure 1-4 , the downcutting switchgear of the present invention comprises an upper cabinet body and a lower cabinet body, a plurality of downcutting switches 1 are installed in an array on the front of the upper cabinet body, and a plurality of downcutting switches 1 are installed on the front side of the lower cabinet body, respectively electrically connected to each downcutting switch 1 A wiring terminal 2. The cabinet door of the upper cabinet body is a glass door, and two locks are installed on the glass door. The operation and wiring of the cabinet are all done on the front, no rear maintenance is required, and the size of the cabinet is small, so it can be installed against the wall or in a corner. It can well solve the problem that there is no extra space in the existing equipment room to install large-size cabinets. Since the operation and wiring are ...

Abstract

The invention discloses a reverse-switching switch cabinet which comprises an upper cabinet body and a lower cabinet body. A plurality of reverse-switching switches are installed on the front face of the upper cabinet body in an array mode, and a plurality of wiring terminals electrically connected with the reverse-switching switches are installed on the front face of the lower cabinet body. The reverse-switching switches are provided with three gears. The reverse-switching switch cabinet is space-saving and convenient to operate, and reduces the influence on the existing system.

Description

technical field [0001] The present invention relates to an undercut switchgear. Background technique [0002] In recent years, more and more subway projects have entered the stage of overhaul and renovation. In order to ensure that the normal operation will not be affected during the renovation and the smooth transition between the old and new systems, the upside-down cabinet has played an important role in it. At present, the inverted cutting cabinets on the market have many shortcomings in practical applications, such as: too large volume, too much space requirements; inconvenient construction; too few alarm information / prompt information; no safe operation mechanism; no fast fault handling mechanism Wait. It is increasingly incompatible with the requirements of construction and transformation. Contents of the invention [0003] The object of the present invention is to provide an undercut switchgear, which saves space, is convenient to operate and reduces the influenc...
