Modularized drawing type transformer for switch cabinet

Abstract

The invention provides a modularized drawing type transformer for a switch cabinet. The modularized drawing type transformer comprises a current transformer, the current transformer is fixedly connected with an insulating cover and is provided with a handcart frame, and the bottom of the handcart frame is provided with a plurality of pulleys. The pulleys are slidably connected to a sliding rail, the sliding rail is arranged in the switch cabinet, and the current transformer is further provided with a service transfer trolley used in cooperation with the current transformer, and the handcart frame is further connected with a handle. The current transformer is provided with a threaded hole, the threaded hole is used for being in threaded connection with the switch cabinet, the switch cabinet is provided with a fixed operation window, and the fixed operation window is used for connecting and fixing the current transformer and the switch cabinet together through threads. According to the present invention, assembly is completed outside the cabinet, the assembled modularized drawing type transformer handcart is pushed into the track in the cabinet through the special service trolley and then is connected with a busbar in the cabinet, so that the operation is safe, the installation is easy and convenient, and the maintenance and overhaul are humanized.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a modular pull-out transformer used for a switch cabinet. Background technique [0002] Most of the existing armored metal-enclosed switchgears are fixed-mounted except for the pull-out type of the handcart room. Refer to the armored AC metal-enclosed switchgear with the Chinese patent publication number CN202333588U , including a busbar room, a cable room, a relay instrument room, and a circuit breaker handcart room in the cabinet. The cable room and the circuit breaker handcart room are connected through the lower part of the cabinet. The rear upper part of the metal-enclosed switchgear, the relay instrument room is set above the busbar room. There is a metal partition between the busbar room, the circuit breaker room and the cable room, including a detachable partition fixed on the cabinet and a movable shutter-type partition. The busbar room is equipped with static con...
