Novel simple bus duct power supply unit

Abstract

The invention provides a novel simple bus duct power supply unit, which comprises a unit shell, a conduction device and an input bus, wherein the input bus penetrates through the inner part of the unit shell; the end part of the input bus is communicated with the conduction device; the conduction device fixedly penetrates through the bottom of the unit shell and is conducted with an electric conduction copper bar in the bus duct; the unit shell comprises an upper cover plate, a middle shell and a lower cover plate; and the upper cover plate and the lower cover plate are independently fixed onthe end parts of the upper side and the lower side of a middle shell. By use of the power supply unit, the unit shell is designed into a split type structure, and the unit shell can be separably installed when the internal conduction device and the input bus are wired. Through the arrangement, the restriction of the own internal space of a box body can be broken through, and therefore, the internal structure is convenient in installation and connection. Meanwhile, since the middle shell is provided with a maintenance door, when the internal part of the box body needs to be checked and repairedin fixed time, only the maintenance door needs to be opened to troubleshoot and overhaul simple faults, a maintenance workload is reduced, and working difficulty is lowered.

Description

technical field [0001] The invention relates to the field of bus duct power supply equipment, in particular to a novel and simple bus duct power supply unit. Background technique [0002] The power supply unit is also called the bus trunk feeder unit, referred to as the feeder power supply unit, which is used for the connection of the total input cable of the main road. The feeder power supply unit can also monitor the voltage, current, frequency and apparent power of each phase of the main road. , Active power, reactive power, power factor, power consumption, load percentage, switch status, temperature and other electrical parameters. Existing power supply units usually have a large space due to the need to install various modules inside, which cannot be installed and used in a small installation space. Due to the structural design of the box body, the small power supply unit needs to be installed in the small space inside the box body for internal wiring, which is not eas...

Problems solved by technology

Existing power supply units usually have a large space due to the need to install various modules inside, which cannot be installed and used in a small installation space. Due to the structural design of the box, the small power supply unit needs to be installed in the small space inside the box for internal wiring and installation, which is not easy to operate
