Low-voltage combined switch cabinet

Abstract

The invention discloses a low-voltage combined switch cabinet, which comprises a cabinet body and a framework. Separator plates are arranged in the cabinet body to divide the interior of the cabinet body into a bus chamber, an instrument chamber, a cable chamber, a switch chamber and a function unit chamber. The switch chamber is defined is composed of a stationary unit, a mobile unit, a plug-in unit and a drawer-type unit. Each chamber is provided with a cabinet door. Each cabinet door is rotationally connected with the framework via a zinc-plated rotation shaft type hinge. Each cabinet door is provided with a mechanical interlocking means. The folding edge of each cabinet door is provided with is additionally provided with a rubber sealing strip. Compared with the prior art, the above low-voltage combined switch cabinet can be applied in the fields of power plants, petrochemical industry, metallurgy, power supply for high-rise buildings and the like. The low-voltage combined switch cabinet serves as a power supply system, wherein the three-phase alternating current frequency thereof is 50 Hz / 60 Hz, and the rated operating voltage thereof is 380 V / 660 V. the low-voltage combined switch cabinet is high in breaking capacity, good in dynamic thermal stability, flexible in electrical solution, convenient in combination, strong in seriation and practicality, novel in structure, and high in protection level.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a low-voltage combined switch cabinet. Background technique [0002] At present, all kinds of low-voltage switchgears on the market generally have the following shortcomings: relatively loose structure, weak series versatility, low breaking capacity, relatively poor dynamic and thermal stability; the distribution circuit layout is not economical and reasonable, Various program units cannot be combined arbitrarily according to the needs of users. In terms of electrical components, domestic or imported components cannot be selected arbitrarily according to the needs of users. Contents of the invention [0003] The object of the present invention is to provide a low-voltage combined switchgear that solves the above problems. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a low-voltage combined switchgear, including a cabinet body and ...
