Reference Standard: GB1984-2003, DL / T846.3-2004 Introduction isolation switch is the power system most widely used in the largest amount of high-voltage switchgear range of applications. As the outdoor isolation switch is the only fully exposed to work in the atmosphere, by environmental climatic conditions affect the most direct and serious electrical equipment, its operating conditions are relatively poor, prone to mechanical or electrical failure. Especially susceptible to finger contact parts invasion rain, dust and harmful gases generated due to poor contact with heat, providing a spring finger pressure due to the pressure to reduce fever and annealing, which is more heat leads to a vicious cycle of finger eventually burn out finger causing the accident. When maintenance is often only pay attention to replacing the obvious failures and broken spring, but for those who can not judge the spring pressure reduction and replacement, so the run again, each finger current distribution varies due to the pressure, the greater the difference between the current The more uneven distribution occurs after a long run of poor contact and overheating. Finger would be a vicious cycle of fever, a finger contact, it might spread throughout the contact is bad. At the same time there are a lot of finger pressure isolation switch is adjustable, if you adjust the pressure is not enough or adjust the pressure of each finger of a difference in the maintenance of the same phenomenon occurs. For the current status of power generation and supply system overhaul, the company has developed its own DBM-8100 high-voltage isolation switch finger pressure tester, it is as long as the test clamp analog sensors in each pair of contacts finger contact position open look, you can display At this point the finger contact pressure and memory. Effective solution to the measurement of finger pressure is a major problem. DBM-8100 high-voltage isolation switch finger pressure tester can also be used to isolate the switch manufacturer of finger pressure test; changing the shape of the pressure sensor can measure the contact breaker finger pressure.
