Corrosion inhibitor for hollow copper conductor of phase modifier cooling water system

The invention discloses a corrosion inhibitor for a hollow copper wire of a phase modifier cooling water system. According to the corrosion inhibitor disclosed by the invention, 1.2. 4-triazole and a nonionic surfactant are used as effective corrosion inhibition components, and the nonionic surfactant is an organic phenol polyoxyethylene ether compound. The corrosion inhibitor is good in product solubility and good in corrosion inhibition effect on copper, corrosion of a phase modifier copper wire coil is inhibited, and the requirement for operation safety of a high-voltage direct-current power transmission system is met; and the water quality condition of the cooling system cannot be influenced by low-dosage dosing. 本发明公开了一种调相机冷却水系统空芯铜导线的缓蚀剂。本发明的缓蚀剂，其采用1.2.4-三唑和一种非离子表面活性剂作为有效缓蚀成分，所述的非离子表面活性剂为有机酚聚氧乙烯醚化合物。本发明的缓蚀剂产品溶解度好，对铜的缓蚀效果好，抑制调相机铜导线线圈的腐蚀，满足高压直流输电系统的运行安全；低剂量加药不会对冷却系统水质条件造成影响。
