Overhaul power box with energy managing function

Abstract

The invention provides an overhaul power box with an energy managing function. The overhaul power box includes a three-phase five-wire circuit, an industrial controller, a contactor and a current transformer. The industrial controller is accessed in a phase wire and a neutral wire of the three-phase five-wire circuit; the contactor is accessed in a phase wire and a neutral wire of the three-phase five-wire circuit, and a switch of the contactor is accessed in three phase wires of the three-phase five-wire circuit; an intermediate relay is connected with the industrial controller, and a switch of the intermediate relay is in series with the contactor; and the current transformer is connected with the industrial controller and accessed in the three-phase five-wire circuit in a single-phase wiring mode. According to the overhaul power box with the energy managing function, a plurality of function apparatuses needed to be arranged respectively are integrated in the industrial controller, individually arrangement is avoided, the arrangement space of the overhaul power box is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an overhaul power box with energy management functions. Background technique [0002] Maintenance power box is widely used in iron and steel metallurgy, electric power, chemical industry, pulp, building materials and other industries to provide temporary power supply and maintenance power supply for production equipment. [0003] At present, the concept of energy saving, emission reduction and information management has been accepted by more and more enterprises. However, the existing overhaul power supply box was designed in the last century. Although it has been continuously improved, it mainly focuses on the use environment such as materials and appearance. [0004] At present, enterprises mainly rely on setting strict rules and regulations to manage the use and maintenance of power boxes, which brings various inconveniences to enterprises. At the same time, the maintenan...

Problems solved by technology

However, the existing overhaul power box was designed in the last century. Although it has been continuously improved, it mainly focuses on the use environment such as materials and appearance.

[0004] At present, enterprises mainly rely on strict rules and regulations to manage the use and maintenance of power boxes, which brings various inconveniences to enterprises.

At the same time, the maintenance power supply box is mostly arranged in an open environment, which easily leads to loss of control in power supply use and management

At present, the use and management of maintenance power boxes are mainly manual, which can no longer meet the requirements of modern enterprises for energy saving, efficiency enhancement, refined management and information management.
