Method for implementing middle phase zero division zero sum by control protection switch
ActiveCN101505052AReduce bouncingReduce the chance of stickingEmergency protective circuit arrangementsOvervoltageElectricity
The invention relates to the technical field of motor control, in particular to a method for realizing medium phase zero-breaking and zero-closing by a control protection switch. The control protection switch is a carrier to realize the method, and comprises a central processing module and a contactor module. The method is characterized by comprising the following steps that: a main CPU singlechip of the central processing module acquires a voltage signal through a voltage signal acquisition circuit, and acquires a current signal through a current signal acquisition circuit; then a three-phase electricity zero-crossing point period is compared with electrified closing mechanical time and power off breaking mechanical time of the contactor module; and a closing or breaking signal after judgment is sent so as to close or break the contactor module of the control protection switch on the medium phase zero point of the three-phase electricity. The method is a simple and effective method for relieving the overvoltage and overcurrent impact, improves service life of the switch body, reduces abrasion of a contactor material, and reduces consumption of noble metal resources.
