Description
Technical field
The utility model relates to a kind of control cabinet, especially a kind of central air-conditioning unit control cabinet.
Background technology
Central air-conditioning unit control cabinet is the device of equipment work such as a kind of compressor of controlling the central air-conditioning unit, fan, water pump, magnetic valve, heater.This device is made up of microcomputer controller, A.C. contactor, overcurrent protection, auxiliary reclay, leader cable terminals, control appliance terminals, sensor terminals, wire casing and control casing etc.Electric current is big during the work of central air-conditioning unit, temperature is high, and requires little, the compact conformation of control cabinet volume.The central air-conditioning unit control cabinet of manufacturer production existed the electrical equipment layout unreasonable in the past, caused the interference of big electric current to microcomputer controller easily, and engineering wiring inconvenience expends defectives such as power wire rod.
Summary of the invention
The purpose of this utility model is to provide a kind of central air-conditioning unit control cabinet, and this central air-conditioning unit control cabinet can reduce the interference to microcomputer controller, is convenient to the engineering wiring, and saving power cable, have compact conformation simultaneously, electrical equipment is arranged neat appearance, clear layer.
The technical solution of the utility model is: a kind of central air-conditioning unit control cabinet, this central air-conditioning unit control cabinet are arranged the electrical equipment of control cabinet and be divided into three physical areas: the light current control zone comprises microcomputer controller, signal output interface, signal input interface; The control output area comprises by fan pump motor overcurrent protection, fan pump motor A.C. contactor, heater magnetic valve auxiliary reclay and output row; Heavy current output area III comprises leader cable terminals, compressor electric motor A.C. contactor, compressor electric motor overcurrent protection; Heavy current output area III is positioned at the control cabinet bottom; the light current control zone is positioned at control cabinet top; the fan water pump A.C. contactor of control output area; the signal output interface of overcurrent protection and light current control zone successively decreases successively by the electromagnetism energy level and arranges; between light current control zone and control output area and heavy current output area and the both sides of casing separate with wire casing; leader cable entrance hole and compressor electric motor cable outlet hole are arranged at the control cabinet bottom; leader cable is connected on the leader cable terminals after penetrating control cabinet by the leader cable entrance hole; the cable of compressor electric motor is drawn after wire hole passes control cabinet by the compressor electric motor A.C. contactor and is connected with compressor electric motor; there are equipment wire hole and signal input hole in the side of control cabinet; sensor signal is connected on the input signal interface after penetrating control cabinet by the hole; fan; pump motor; magnetic valve; the output of heater device passes control cabinet by end row through wire hole, divides the fan that is clipped to unit then; water pump; heater; on the equipment such as magnetic valve.
Advantage of the present utility model is: the heavy current output area is positioned at the control cabinet bottom, is convenient to the access of engineering medium power cable and picking out of compressor electric motor cable, and has shortened the length of cable, has saved material.And the microcomputer controller in the light current control zone is positioned at control cabinet top, away from high-current device the work electromagnetic interference and the thermal source that the time are produced.Simultaneously; the device that electric currents such as the fan of control output area, water pump A.C. contactor, overcurrent protection are less and the devices such as signal output interface of light current control zone are arranged by electromagnetism energy level production decline law successively; to heavy current produce electromagnetic interference certain isolation and buffering effect are arranged; thereby can reduce the interference effect of big electric current greatly, improve the reliability of controller microcomputer controller.From integral layout, because congener device permutation and combination in an orderly manner can reach attractive in appearance neat, well-bedded effect.
