Description

A modular chassis for street lamp equipment

Technical Field

The utility model relates to the technical field of modular chassis, in particular to a modular chassis for street lamp equipment.

Background Art

Modular chassis refers to modular integration of equipment such as UPS, power supply, cabinet, monitoring, and control that need to be arranged in the traditional computer room into an overall cabinet system. It has the advantages of centralized equipment and modular management. At present, the modular chassis of street lights are equipped with various electrical control components required for smart street lights, such as: disconnectors, molded case circuit breakers, AC transformers, contactors, electric meters, street light controllers, 3P circuit breakers, fuses, etc.

The 3P circuit breakers in the existing modular chassis of street lamps are basically connected side by side on the same mounting rail. Three short and thick wires are installed between the fuse below and the fuse. When the 3P circuit breaker is damaged, the staff needs to replace it. During the replacement, in order not to affect the use of the street lamp, it is generally operated with power on. First, turn off the 3P circuit breaker, and then loosen the clamping screw. Since the top wires generally have a large margin for easy extraction, the top wires can be directly extracted with pliers, while the short and thick wires at the bottom are basically close to a straight line. When removing the 3P circuit breaker, you need to clamp the wire with pliers, and then use great force to bend it to pull it out. Finally, use a flat head screwdriver to push down the 3P circuit breaker card to complete the disassembly. When installing, in order to avoid electric shock, you need to first install the 3P circuit breaker on the mounting rail, and then install the top wires and the short and thick wires at the bottom. The top wires are easier to install, while the short and thick wires at the bottom must be clamped with pliers, then bent with great force, and then inserted into the mounting hole. Due to the narrow space, it sometimes takes multiple attempts to succeed, which is very laborious.
