Abstract

The invention discloses a modularized medium-voltage solid soft starter cabinet, which comprises a removable type hypobaric chamber arranged on the upper part of a cabinet body, a hyperbaric chamber arranged at the back part of the removable type hypobaric chamber, and a cable chamber arranged below the cabinet body, wherein a hypobaric chamber door is arranged on the front part of the removable type hypobaric chamber, one side of the hypobaric chamber is locked by using a bolt, and the other side of the hypobaric chamber is provided with a hinge; the front part of the cable chamber is provided with a cable chamber door, one side of the cable chamber door is fixed on a bending angle at one side of the cabinet body by adopting a screw lock; the cable chamber door can be opened by only dismantling the screw lock; the other side of the cable chamber door is provided with a hinge; an incoming wire and a outgoing wire of the soft starter cabinet are connected in the cable chamber; a fuse module is arranged in the cable chamber, the fuse module is connected with a rear copper bar by using a cable; and the fuse module can be installed or dismantled at any time according to the requirement of a user. Due to the adoption of a modular structure, the modularized medium-voltage solid soft starter cabinet has the advantages of convenience for transportation and maintenance and flexibility in installation.

Description

technical field [0001] The invention belongs to the field of motor control, in particular to a modular medium-voltage solid-state soft starter cabinet. technical background [0002] A soft starter is a novel motor control device that integrates motor soft start, soft stop, light-load energy saving and multiple protection functions. It is a three-phase parallel connection between the power supply and the controlled motor. Brake tube and its electronic control circuit. [0003] However, due to the low-voltage control system, medium-voltage contactor, fuse and other equipment installed in the existing soft starter cabinet, the cabinet body is large in size and heavy in weight, which is inconvenient for installation, maintenance, and safety interlocking. Therefore, the soft starter cabinet needs to be improved in terms of equipment installation, maintenance, and modular design. This is the technical problem that the existing soft starter cabinet needs to solve. Contents of t...
