Problems solved by technology

The existing 1 / 2 drawer unit with maintenance in front of the screen and wiring on the screen side uses a distribution adapter to realize the on-off operation of the main circuit and the control circuit. This connection structure will appear a primary connector of the drawer body after a period of use. Unreliable contact with the distribution adapter, prone to serious consequences of burning a connector or electrical device
The carrying current capacity of each unit in the adapter can only reach 63A, which cannot meet the requirements of larger capacity starting units
In addition, due to the small space of the distribution adapter, there are many secondary transfer wires inside, the heat dissipation effect is not good, and there are certain potential safety hazards

Abstract

The invention discloses a 1 / 2 drawer unit of a drawer type power distribution cabinet. The 1 / 2 drawer unit comprises a drawer body and a plurality of primary movable inserts and secondary movable inserts. The drawer body comprises a drawer panel and drawer lateral boards on two sides. Every primary movable insert comprises an inserting type switch body, a switch base and a switch base installation frame, wherein the switch base installation base is arranged in the middle of a power distribution cabinet framework, and the bottom of the drawer body is supported on a separation board of a drawer layer through a plurality of guide rails. The secondary movable inserts are nine-needle connectors arranged in the inserting type switch bodies, primary plugs on the inserting type switch bodies are respectively inserted into corresponding sockets on the switch base, and inserting needles of the nine-needle connectors are inserted into corresponding jacks on the switch base. The maximum current capacity of the 1 / 2 drawer unit is improved to 250A, so that requirements for exchanging of the drawer type power distribution cabinet are met. The primary movable inserts and the secondary movable inserts of the inserting type switch body are reliable and accurate in contact, and the radiating effect is good.

Description

technical field [0001] The invention relates to a low-voltage power distribution device, in particular to a drawer unit of a low-voltage power distribution cabinet, and belongs to the technical field of low-voltage electrical equipment.
