Description

Technical Field

[0001] This utility model relates to the field of high and low voltage switchgear technology, and more specifically, to a high and low voltage switchgear for a combined transformer. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are few circuits; motor control centers are used in situations where the load is concentrated and there are many circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] When installing high and low voltage equipment or other switching equipment, most existing distribution cabinets use a snap-fit ​​connection with the mounting bracket inside the cabinet. However, since the mounting bracket for installing high and low voltage or switching equipment is threaded to the cabinet, and the volume and size of the high and low voltage or switching equipment on the mounting bracket are different, the vertical distance also needs to be adjusted. During the adjustment process, tools are needed to replace the equipment, and the frequent use of screws will reduce their lifespan and cause stripping.

[0004] Therefore, we have made improvements to this and proposed a combined high and low voltage switchgear for transformers. Utility Model Content

[0005] The purpose of this utility model is to address the issue that the mounting bracket for installing high and low voltage or switchgear is connected to the cabinet by threads. The high and low voltage or switchgear on the mounting bracket have different volumes and sizes, and the vertical distance also needs to be adjusted. During the adjustment process, tools are required for replacement. At the same time, the frequent use of screws will reduce their lifespan and cause problems such as stripping.

[0043] A partition chamber 18 is provided between the ventilated panel 16 and the rear surface of the cabinet 1. The rear sealing door 17 is placed in the slot in the partition chamber 18 on the rear surface of the cabinet 1. The heat dissipation component is located on the top side of the partition chamber 18, the first mounting chamber 13, and the second mounting chamber 14. A through groove 24 is provided between the top of the cabinet 1 and the second mounting chamber 14, the first mounting chamber 13, and the partition chamber 18.
