Remote-control type air-conditioning three-phase circuit adjusting system

Abstract

The invention provides a remote-control type air-conditioning three-phase circuit adjusting system, and the system comprises a three-phase relay I and a three-phase relay II in parallel connection with the three-phase relay I. The wire incoming ports A1, B1 and C1 of the three-phase relay I are electrically connected with an external three-phase power supply, and the wire outgoing ports A2, B2 and C2 of the three-phase relay I are respectively connected with the wire incoming ports A, B and C of an air conditioning phase sequence detection circuit board. The wire incoming ports A1, B1 and C1 of the three-phase relay II are respectively connected with the wire incoming ports A1, C1 and B1 of the three-phase relay I, and the wire outgoing ports A2, B2 and C2 of the three-phase relay II are respectively connected with the wire outgoing ports A2, B2 and C2 of the three-phase relay I. The three-phase relay I and the three-phase relay II are respectively connected with a relay control unit through a voltage relay I and a voltage relay II. The system adjusts the three-phase electric connection of an air conditioner simply and conveniently through the relay control unit, enables the air conditioner to work normally, prevents an installation worker from carrying out disassembly and new installation and connection, effectively reduces the unnecessary operation of the installation worker, and is safe in operation.

Description

technical field [0001] The invention belongs to an air conditioner control circuit, in particular to a remote control air conditioner three-phase circuit inverter system. Background technique [0002] With the improvement of people's living standards, various household appliances are gradually entering people's lives. Among them, air conditioners, as an electrical appliance that improves people's living environment, are gradually entering thousands of households. However, most of the air conditioners are connected in three phases, and there is no obvious distinction between the three phase lines. During the installation process, connection errors are prone to occur, causing the air conditioner to fail to operate normally. At this time, the connection relationship between the three phases needs to be readjusted; Implementing regional management, the staff may change the three-phase connection during the usual maintenance process, and the air conditioner that is working normal...
