Off-line installation system and off-line wiring method for secondary summary terminals of low-voltage cabinets

Abstract

The invention relates to an installation system in a low-voltage cabinet and a wiring method, in particular to an off-line installation system of a low-voltage cabinet secondary-summarizing terminal and an off-line wiring method and belongs to the technical field of power distribution equipment. The off-line installation system can complete secondary terminal installation and summarizing without waiting for cabinet body size confirmation of a drawing, and secondary terminal installation positions and secondary wire length are fixed and are not influenced by cabinet width / depth. After wire length fixing, a secondary-summarizing wire can achieve off-line operation, and the production efficiency is improved by more than two times. In addition, vertical row cover plates are unified to have unique size, and the standardization level is high. After secondary terminal summarizing and fixing, the wire length can be shortened for 1 meter compared with an original one, and the lead wire consumption is greatly reduced. The user-side wiring space is increased through primary, secondary and tertiary wire separated layout, and the safety performance is improved.

Description

technical field [0001] The invention relates to an installation system and a wiring method in a low-voltage cabinet, in particular to an offline installation system and an offline wiring method for a secondary summarization terminal of a low-voltage cabinet, and belongs to the technical field of power distribution equipment. Background technique [0002] The main function of the low-voltage cabinet is to switch, control and protect electrical equipment during the process of power transmission and distribution and power conversion in the power system. It can be used in power plants, substations, rail transit, data centers, petrochemicals, factories and mines. , Residential districts and other different occasions. The components inside the cabinet are composed of circuit breakers, disconnectors, load switches, transformers and various protection devices. According to the type of low-voltage cabinets, it can be divided into drawer cabinets, fixed cabinets, fixed partition cabi...

AI Technical Summary

Problems solved by technology

In all the current low-voltage cabinets in China, the installation position of the secondary terminal summary of the drawer cabinet is generally located on the left rear side of the cabinet, close to the door of the cabinet. And the summary wiring harness cannot achieve standardized offline operation. The workshop workers must get the engineering drawings and confirm the size of the cabinet before making the wiring harness.

Unable to work in advance, low production efficiency

In addition, since the primary terminal is also on the left rear side of the cabinet, when there are many circuits in the drawer cabinet, it is easy to cause insufficient wiring space for the primary line and the secondary line, and the safety performance is low.
