Detection method and system of wire connection of single-phase air-conditioner

Abstract

The invention discloses a detection method and system of wire connection of a single-phase air-conditioner. The detection method comprises steps of turning on a power supply of a to-be-detected single-phase air conditioner, disconnecting a ground wire, adjusting a universal meter to an alternating-current voltage shift, connecting a black meter pen with the ground wire of the alternating current power supply connected with the single-phase air conditioner, connecting a red meter pen with a metal housing of the to-be-detected single-phase air conditioner and acquiring voltage reading; judging whether the acquired voltage reading meets requirements, and if the detected voltage reading is not higher than 36V, determining that the live line and the null line of the to-be-detected single-phase air conditioner are correctly connected; and if the detected voltage reading is higher than 36V, determining that the live line and the null line of the to-be-detected single-phase air conditioner are reversely connected. According to the invention, whether wires are correctly connected can be finished only by use of a universal meter in the whole detection processes without turning on an electric control box of the air conditioner; two meter pens of the universal meter are successively connected with the metal housing of the air conditioner and the ground wire of a power supply; whether wires are correctly connected can be judged through the size relation between the potential difference between the housing of the air conditioner and the ground wire, and the safe voltage; and the detection method is simple and feasible.

Description

technical field [0001] The invention relates to the technical field of air conditioner detection, and more specifically, to a single-phase air conditioner connection detection method, and also to a single-phase air conditioner connection detection system. Background technique [0002] With the development of science and technology and the improvement of material living standards, people pay more and more attention to the safety of daily household appliances. For the field of air conditioning equipment, especially for single-phase air conditioners, when the ground wire of the equipment is in poor contact or the leakage protection device fails, if the neutral and live wires of the air conditioner are reversed, the chassis will have more than 100 volts to the ground in the off state. The induced voltage may easily cause maintenance personnel or users to be shocked. [0003] The current single-phase air-conditioning power line wiring is correct manually. The reverse connection ...
