Abstract

The invention relates to the technical field of power supply and distribution, communication and automatic control, in particular to a dual-voltage continuous acquisition combined feed switch which comprises a box body shell and cable connectors. The interior of the box body shell is divided into a 1140V isolation switch cavity, a 1140V / 400A driving unit cavity, a 660V isolation switch cavity, a 660V driving unit cavity, a low-voltage cavity, an explosion-proof wiring cavity and an intrinsic safety wiring cavity; the cable connectors comprise a 1140V input side cable connector, a 1140V outputside cable connector, a 660V input side cable connector and a 660V output side cable connector. According to the invention, the design of 1140V and 660V double voltages is provided, the double voltageclasses do not interfere with each other, the 1140V and 660V voltage explosion-proof structures are processed in a cavity division manner, the cable connectors at the input side and the output side cannot be universally used and interchanged, the equipment safety and stability are high, and the automation program is high.

Description

technical field [0001] The invention relates to the technical fields of power supply and distribution, communication and automatic control, in particular to a dual-voltage continuous mining combined feed switch. Background technique [0002] At present, most of the low-voltage feed switches used in domestic coal mines are single feed switches, which are used to feed continuous miners, bolters, feed crushers, shuttle cars, bolt and cable machines, electric welding machines, water pumps, and lighting. and other load power supply and provide protection. The current existing feed switch has the following deficiencies: [0003] 1. The existing feeder switches are mainly single feeder switches. There are many equipments in the continuous excavation working face of coal mines. It uses more cable connectors and the cost is higher; [0004] 2. The existing continuous excavation working face has limited space for equipment trains, and the existing installation and matching methods ...
