An electrical safety testing method for photovoltaic air conditioners

Abstract

The invention discloses an electric safety test method of a photovoltaic air conditioner. The electric safety test method of the photovoltaic air conditioner includes the steps that a draught fan, a compressor, a photovoltaic module and an alternating current module of the photovoltaic air conditioner are connected with a terminal integrator; an electric safety tester is connected with the terminal integrator; voltage is synchronously loaded at the input and output ends of a rectifying plate and the input and output ends of an inversion plate, and data of the electric safety tester is read. Byadopting the electric safety test method of the photovoltaic air conditioner, one-time wiring electrification is conducted to complete electric safety tests on the photovoltaic module and the alternating current module of the photovoltaic air conditioner, one-time electrification and electric safety tests on the compressor are completed at the same time, mainboard breakdown potential hazards caused by voltage differences are eliminated, the safe and efficient electric safety tests are achieved, control parameters are more accurate and rapider, the troubleshooting efficiency is high, the outgoing quality of the photovoltaic air conditioner is improved, wiring error hidden hazards brought by double-module single detection are solved, production operation is convenient and rapid to conduct,the universality is high, and after debugging, the electric safety test method of the photovoltaic air conditioner can be applied to rapid detection of the photovoltaic module and the alternating current module.

[0002] Photovoltaic air conditioners are green and environmentally friendly, in line with the country's development strategy for clean energy, and have attracted more and more attention from customers. The safety of photovoltaic air conditioners is one of the key issues that both customers and manufacturers are concerned about. The electrical safety operation specification for air conditioners is blank, and it is urgent to develop a method to realize the electrical safety detection of photovoltaic air conditioners, so as to realize the rapid and comprehensive detection of electrical safety of photovoltaic air conditioners, especially the photovoltaic multi-connected air conditioner controller includes two major components: photovoltaic modules and AC modules. module, a method is needed to detect the electrical safety of the two modules at the same time, shorten the electrical safety inspection cycle, and improve production efficiency. The current test method repeats the unwiring and wiring actions, and the probability of wrong wiring caused by multiple unwiring is high. The operation method of medium and light photovoltaic units is not universal enough, and the electrical components of the unit cannot be effectively protected while completing the inspection
