目的研究新型气相防锈剂对电器设备的防护效果及电性能的影响,解决电器设备服役过程中的腐蚀防护问题。方法采用中性盐雾试验对新型气相防锈剂对电器设备的防护效果进行测试,并通过绝缘电阻、介电常数、电容、表面电阻、体积电阻、电阻、耐击穿电压等测试了新型气相防锈剂对电器元件、电器设备电性能的影响。结果中性盐雾试验240 h后,无新型气相防锈剂保护的电器设备锈蚀严重,有新型气相防锈剂保护的电器设备锈蚀相对微弱;电路板原材料环氧树脂板、安规电器元件、电器设备与气防锈发散体直接接触720 h后,各自的电性能基本上没有变化,同时电器设备的正常功能也不受影响。结论新型气相防锈剂对电器设备有较好的防护效果,且不影响其电性能,可将其应用到电器设备实际运行过程中,解决电器设备服役过程中的腐蚀防护问题。

Objective To Study the protective effect of a new vapor phase corrosion inhibitor and its influence on the performance of electrical equipment, and to solve the problem of corrosion protection in the service process of electrical equipment. Methods The protective effect of the new vapor phase corrosion inhibitor on electric equipment was analyzed by salt spray test technology. The influence of the new vapor phase corrosion inhibitor on the electrical performance of the equipment was tested by measuring the insulation resistance, dielectric constant, capacitance, surface and volume resistance, resistance and high breakdown voltage. Results After 240 h of neutral salt spray test, the electrical equipment without the protection of the new vapor phase corrosion inhibitor was seriously rusted, while the electrical equipment with the protection of the new vapor phase corrosion inhibitor showed relatively weak corrosion. After 720 h exposure to the new vapor phase corrosion inhibitor, the circuit board materials epoxy resin plate, electrical components and electrical equipment showed basically no change in their electrical performance. At the same time, the normal operation of the electrical equipment was not influenced. Conclusion The new vapor phase corrosion inhibitor had relatively good protective effect on the electrical equipment, meanwhile, it did not affect the performance of the electrical equipment. It can therefore be effectively applied to the electrical equipment in the process of actual operation to solve the problem of corrosion protection in the service process of electrical equipment.
