Low voltage draw out type switch cabinet

Abstract

The invention relates to a low-voltage withdrawable switch cabinet, which belongs to the field of electrical equipment. The invention comprises a cabinet body, which is a frame structure, and is divided into a busbar compartment at the rear of the cabinet, a functional unit compartment at the left side of the front part of the cabinet, a cable compartment at the right side of the front part of the cabinet, the busbar compartment and the functional unit The compartments are separated by multifunctional partitions, the cable compartments are separated from the busbar compartments, and the functional unit compartments are separated by steel plates. The functional unit compartments are provided with at least one movable drawer. The present invention addresses the shortcomings of existing equipment , in view of the problem that the heat of the joint is not easily monitored by early warning and dust prevention when the equipment in the switch cabinet is running, effective monitoring of the heat fault of the joint in the switch cabinet can monitor the temperature of the joint in the switch cabinet in real time, and play a role in preventing joint accidents At the same time, this system effectively prevents the entry of dust and ensures the safety of system operation. It has a simple structure and strong reliability, and is suitable for promotion and use.

Description

technical field [0001] The invention relates to a low-voltage withdrawable switch cabinet, which belongs to the field of electrical equipment. Background technique [0002] With the rapid growth of the national economy in recent years, the development of the power grid has also ushered in new historical opportunities. The MNS low-voltage withdrawable switchgear is suitable for power plants, substations, petrochemicals, metallurgical rolling steel, light industry and textiles and other factories and mines and residential quarters. In high-rise buildings and other places, it is used for power conversion, distribution and control of power distribution equipment for power systems with AC 50~60Hz and rated working voltage 660V and below. [0003] However, in practical applications, some shortcomings of the switchgear itself also appear, such as the low-voltage incoming switchgear of the main transformer is prone to overheating, and the temperature monitoring system is lacking i...
