Problems solved by technology

[0003] The commonly used AC contactors are usually opaque or poorly transparent, and it is inconvenient to observe the internal structure. When the contact fails, it is difficult to find the fault point through naked eye observation. It is necessary to use a multimeter and other equipment to detect it, which is inconvenient for maintenance. , so that the cost of maintenance time is greatly increased, which is not conducive to saving manpower and material resources

Abstract

The invention discloses an AC contactor with fault display, which includes an AC contactor body, a controller, and an indicator light; the invention uses the controller to collect pulse signals generated when each contact is powered on and off, and the controller uses the pulse signal to Judging whether each contact is faulty, and according to the judgment result, control the indicator light to indicate whether each contact is faulty or not. The invention has a simple structure, and the staff can intuitively judge the faulty contacts, which greatly saves fault detection time and manpower and material resources.

Description

technical field [0001] The invention belongs to the field of electrical low-voltage complete sets of electrical equipment, in particular to an AC contactor with fault display. Background technique [0002] With the rapid advancement of my country's economy and technology, infrastructure such as building construction and fire protection systems have developed in an all-round way, and the demand has increased year by year. The low-voltage switchgear plays the role of control, protection, measurement conversion and distribution of electric energy in the low-voltage power supply and distribution system. With the continuous development of power distribution technology, low-voltage component technology and automation technology, the complete set of switchgear has also developed from traditional power distribution to intelligent development, and has entered a new stage of development. [0003] The commonly used AC contactors are usually opaque or poorly transparent, and it is inco...
