Embodiment Construction

[0019] In order to make the present invention more obvious and comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0020] The invention provides a maintenance-free modular low-voltage switch cabinet, which adopts a modular installation method, is convenient for disassembly and assembly, does not need maintenance, and is convenient and quick to repair. like figure 1 , figure 2 As shown, it includes the following modules: switch unit 3 , bus bar room 1 , instrument room 2 . The busbar room 1, the instrument room 2, and the switch unit 3 are all independent modular structures, and the busbar room 1, the instrument room 2, and the switch unit 3 are connected by plugging. The busbar room 1, the instrument room 2, and the switch unit 3 are all closed structures. A bushing 5 is provided between the busbar compartment 1 and the switch unit 3 . There is a busbar in the busbar compartment 1, the busbar enters from the t...

Abstract

The invention discloses a maintenance-free modular low-voltage switch cabinet which is characterized by comprising a bus chamber, an instrument chamber and a switch unit, the bus chamber, the instrument chamber and the switch unit are all of independent modular structures, and the bus chamber, the instrument chamber and the switch unit are connected in a pluggable mode. A modular installation modeis adopted, the disassembly and assembly are convenient, the maintenance is not needed, and the overhauling is convenient and rapid.

Description

technical field [0001] The invention relates to a maintenance-free modular low-voltage switch cabinet, belonging to the technical field of electrical equipment. Background technique [0002] Low-voltage switchgear is a kind of electrical equipment used for the transmission and control of electrical energy, which can ensure the safety of electrical equipment and personnel. With the rapid economic development, all sectors of society have put forward higher requirements for the reliability of power supply. Research on new low-voltage switchgear is an important indicator to improve the reliability of power supply. When maintenance and repair of existing low-voltage switchgear is carried out, it is inconvenient to disassemble and assemble, which takes a long time and reduces the reliability of power supply. The specific disadvantages are as follows: [0003] 1. The existing low-voltage switchgear has a relatively simple power supply mode, and the power outage and maintenance ti...
