High Voltage Isolation Switch Contact Pressure Tester
WA1401
Wuhan Sangao Electrical Test Installations Limit Co.
Isolation switch is the high voltage switch equipment, it was large and frequently use in power system . The outdoor isolating switch is the only completely exposed in the atmospheric environment electrical equipment, It is also a electrical equipment affected by climatic conditions influence the most direct and most serious. The operating conditions is relatively poor, It is easy to generate fault of mechanical or electrical. Especially the finger contact part is easy to be affected by rain, dust and harmful gas invasion, resulting in poor contact caused fever, provide the spring with contact pressure due to heating and annealing for reducing the pressure, so that more cause finger heat form vicious spiral eventually burn out finger accident. In maintenance often only pay attention to replace the obvious failure and fracture of spring, but spring to reduce the pressure can not judge and replacement, so again in the operation, each finger current distribution by the pressure difference, The greater the difference between the current distribution is not uniform, long-term operation will occur is bad and the overheating. Fever finger will be vicious spiral, a finger contact bad will spread over the entire bad contact. At the same time, there are a lot of isolating switch contact pressure can be adjusted, if in maintenance adjustment pressure is not enough or each finger to adjust the pressure difference will also appear afore-mentioned phenomena.
