gc2 series switch capacitor contactor-ag凯发k8国际
an overview of the
gc2 series switch capacitor contactor(hereinafter referred to as the contactor)mainly applied to ac 50 hz,rated voltage 380 v electric power capacitor compensation loop through and breaking,to adjust the power factor of power system,contactor suppress flow ability,make through to the peak flow is not more than 20 times the rated working current,working conditions are the same as the gc1 series contactor shall apply。
gc2 series switch capacitor contactor,because it is on the b series ac contactor products derived form,so the technical performance indicators in addition to the mechanical and electrical life life,the rest of the technical performance and b series ac contactor same current specifications of the products is the same。this product adopts the two groups on either side of the assembly in the contactor special auxiliary contacts and current limiting and forced a discharge resistor,when the input capacitors,first by the string of limited flow resistance of the auxiliary contact closure,the capacitor charging into the current limit within the capacitor rated current ie 20 times,then,closed contact the main contact,to appear the second time of surge current also limits within 20 times。this structure than the original contactor + current-limiting reactor,omit a set of contactor and reactor,investment costs have bigger savings。the species overcoming cj16 contactor、no discharge resistance cj19 series contactor,the second input to a capacitor residual voltage is too high,so that the contactor to burn resistor,even contact welding defects,with a discharge resistor,when the contactor will run capacitor after cut away from the grid,special auxiliary contactor contact closed normally closed contacts,by forcing the capacitor discharge resistor nipple discharge,in order to make sure the capacitor in the second to drop its remaining voltage less than 50 v,meet the requirements of technical conditions,to avoid the current limiting resistor burning and welding contact the main contact。gc2 series 5 current specifications of the switch capacitor contactor,advanced design is novel, high operating reliability,high technical and economic indicators,compensation capacitor is an indispensable component in the cupboard。
conform to the standard:
